QBConnector Component

Properties Methods Events Config Settings Errors

The QBCONNECTOR component is a utility that allows you to connect your QuickBooks Integrator applications to remote QuickBooks instances.

Syntax

TiqbQBConnector

Remarks

The QBConnector component is a lightweight web server which listens for HTTP requests originating from the QuickBooks Integrator components. Each request sent to the QBConnector by a QuickBooks Integrator component contains the XML data to be communicated to QuickBooks as well as configuration settings specifying how the connection is to be opened. The QBConnector then communicates with QuickBooks via COM, and returns the QuickBooks response (or an error message) in the HTTP reply.

Using the QBConnector component is easy. Simply set Listening to True, and the component will begin listening for incoming messages on the specified LocalPort. The messages will be processed by the QuickBooks application that is running on the same machine as the QBConnector, and the results will automatically be returned to the requesting client.

Basic authentication is enabled by default, meaning the connecting clients must present a user name and password in the QBConnectionString of the component they're using. The supplied user name and password are checked against the list of AuthorizedUsers. If no user in the list matches the supplied credentials, the Authorization event will fire with the Accept parameter set to false. If the user was found in the list of AuthorizedUsers then the parameter will be set to True. You may override this functionality by setting the Accept parameter inside the Authorization event manually. If no "Authorization" header supplied in the request, the Authorization event will fire with blank User and Password parameters.

Note that the AuthorizedUserQBConnectionString will be used to make the connection to QuickBooks for a user found in the AuthorizedUsers collection.

Any of the QuickBooks Integrator components can connect to the QBConnector using the QBConnectionString property of any of the components. For instance, an example using the Invoice component follows: Invoice.QBConnectionString = "URL='http://www.foo.com:2080'" User='Foo' Password='Bar'";

Using SSL along with a digital certificate greatly increases the security of the Remote Connector. SSL will encrypt all data transmitted across the network, ensuring that only the Connector can read incoming requests, and that only the requesting client can read the QuickBooks responses. This prevents unauthorized parties from accessing your QuickBooks data. You should use a full digital certificate on the server (Connector) side, and this will contain a public key and a private key. This version of your certificate should be kept private. You may export a version of the certificate containing the public key only, and distribute this to all clients that need to communicate with the Connector.

To use this functionality, set the SSLCert with a valid certificate and then change the SSLStartMode to sslImplicit. Now all clients must post to the QBConnector using HTTPS. eg: Invoice.QBConnectionString = "URL='https://www.foo.com:2080' User='Foo' Password='Bar'"; // https instead of http

The client (in these examples Invoice) has an SSLServerAuthentication event that will fire when the server presents its certificate. If the public key presented by the QBConnector is trusted by the system, the Accept parameter will be True. If it is not trusted by the system (Accept is False), you should inspect the certificate and if valid, override by setting Accept to True.

Default Value

false

Remarks

You may use this property to determine whether the component is currently connected to QuickBooks.

This property is read-only and not available at design time.

Data Type

Boolean

EnableSSL Property (QBConnector Component)

Indicates whether server starts in SSL-mode.

Syntax

__property bool EnableSSL = { read=FEnableSSL, write=FSetEnableSSL };

Default Value

false

Remarks

This property must be set before setting Listening to True. When EnableSSL is True, plaintext connections to the component will be rejected.

This property is not available at design time.

Data Type

Boolean

Listening Property (QBConnector Component)

If set to True, the component accepts incoming connections on LocalPort.

Syntax

__property bool Listening = { read=FListening, write=FSetListening };

Default Value

False

Remarks

This property indicates whether the component is listening for connections on the port specified by the LocalPort property.

Note: Use the StartListening and StopListening methods to control whether the component is listening.

This property is not available at design time.

Data Type

Boolean

LocalHost Property (QBConnector Component)

The name of the local host or user-assigned IP interface through which connections are initiated or accepted.

Syntax

__property String LocalHost = { read=FLocalHost, write=FSetLocalHost };

Default Value

Remarks

The LocalHost property contains the name of the local host as obtained by the gethostname() system call, or if the user has assigned an IP address, the value of that address.

In multi-homed hosts (machines with more than one IP interface) setting LocalHost to the value of an interface will make the component initiate connections (or accept in the case of server components) only through that interface.

If the component is connected, the LocalHost property shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multi-homed hosts (machines with more than one IP interface).

NOTE: LocalHost is not persistent. You must always set it in code, and never in the property window.

Data Type

String

LocalPort Property (QBConnector Component)

The TCP port in the local host where the component listens.

Syntax

__property int LocalPort = { read=FLocalPort, write=FSetLocalPort };

Default Value

2080

Remarks

The LocalPort property must be set before QBConnector starts listening. If its value is 0, then the TCP/IP subsystem picks a port number at random. The port number can be found by checking the value of the LocalPort property after Listening is set to True.

The service port is not shared among servers (i.e. there can be only one QBConnector 'listening' on a particular port at one time).

The default value for LocalPort is 2080.

Data Type

Integer

SSLAuthenticateClients Property (QBConnector Component)

If set to True, the server asks the client(s) for a certificate.

Syntax

__property bool SSLAuthenticateClients = { read=FSSLAuthenticateClients, write=FSetSSLAuthenticateClients };

Default Value

false

Remarks

This property is used in conjunction with the SSLClientAuthentication event. Please refer to the documentation of the SSLClientAuthentication event for details.

Data Type

Boolean

SSLCertEncoded Property (QBConnector Component)

This is the certificate (PEM/base64 encoded).

Syntax

__property String SSLCertEncoded = { read=FSSLCertEncoded, write=FSetSSLCertEncoded };
__property DynamicArray<Byte> SSLCertEncodedB = { read=FSSLCertEncodedB, write=FSetSSLCertEncodedB };

Default Value

Remarks

This is the certificate (PEM/base64 encoded). This property is used to assign a specific certificate. The SSLCertStore and SSLCertSubject properties also may be used to specify a certificate.

When SSLCertEncoded is set, a search is initiated in the current SSLCertStore for the private key of the certificate. If the key is found, SSLCertSubject is updated to reflect the full subject of the selected certificate; otherwise, SSLCertSubject is set to an empty string.

This property is not available at design time.

Data Type

Byte Array

SSLCertStore Property (QBConnector Component)

This is the name of the certificate store for the client certificate.

Syntax

__property String SSLCertStore = { read=FSSLCertStore, write=FSetSSLCertStore };
__property DynamicArray<Byte> SSLCertStoreB = { read=FSSLCertStoreB, write=FSetSSLCertStoreB };

Default Value

"MY"

Remarks

This is the name of the certificate store for the client certificate.

The SSLCertStoreType property denotes the type of the certificate store specified by SSLCertStore. If the store is password protected, specify the password in SSLCertStorePassword.

SSLCertStore is used in conjunction with the SSLCertSubject property to specify client certificates. If SSLCertStore has a value, and SSLCertSubject or SSLCertEncoded is set, a search for a certificate is initiated. Please see the SSLCertSubject property for details.

Designations of certificate stores are platform-dependent.

The following are designations of the most common User and Machine certificate stores in Windows:


MY	A certificate store holding personal certificates with their associated private keys.
CA	Certifying authority certificates.
ROOT	Root certificates.

When the certificate store type is PFXFile, this property must be set to the name of the file. When the type is PFXBlob, the property must be set to the binary contents of a PFX file (i.e. PKCS12 certificate store).

Data Type

Byte Array

SSLCertStorePassword Property (QBConnector Component)

If the type of certificate store requires a password, this property is used to specify the password needed to open the certificate store.

Syntax

__property String SSLCertStorePassword = { read=FSSLCertStorePassword, write=FSetSSLCertStorePassword };

  cstBCFKSBlob=22,
  cstPKCS11=23,
  cstAuto=99
};

Default Value

cstUser

Remarks

This is the type of certificate store for this certificate.

The component supports both public and private keys in a variety of formats. When the cstAuto value is used the component will automatically determine the type. This property can take one of the following values:


0 (cstUser - default)	For Windows, this specifies that the certificate store is a certificate store owned by the current user. Note: this store type is not available in Java.
1 (cstMachine)	For Windows, this specifies that the certificate store is a machine store. Note: this store type is not available in Java.
2 (cstPFXFile)	The certificate store is the name of a PFX (PKCS12) file containing certificates.
3 (cstPFXBlob)	The certificate store is a string (binary or base64-encoded) representing a certificate store in PFX (PKCS12) format.
4 (cstJKSFile)	The certificate store is the name of a Java Key Store (JKS) file containing certificates. Note: this store type is only available in Java.
5 (cstJKSBlob)	The certificate store is a string (binary or base64-encoded) representing a certificate store in Java Key Store (JKS) format. Note: this store type is only available in Java.
6 (cstPEMKeyFile)	The certificate store is the name of a PEM-encoded file that contains a private key and an optional certificate.
7 (cstPEMKeyBlob)	The certificate store is a string (binary or base64-encoded) that contains a private key and an optional certificate.
8 (cstPublicKeyFile)	The certificate store is the name of a file that contains a PEM- or DER-encoded public key certificate.
9 (cstPublicKeyBlob)	The certificate store is a string (binary or base64-encoded) that contains a PEM- or DER-encoded public key certificate.
10 (cstSSHPublicKeyBlob)	The certificate store is a string (binary or base64-encoded) that contains an SSH-style public key.
11 (cstP7BFile)	The certificate store is the name of a PKCS7 file containing certificates.
12 (cstP7BBlob)	The certificate store is a string (binary) representing a certificate store in PKCS7 format.
13 (cstSSHPublicKeyFile)	The certificate store is the name of a file that contains an SSH-style public key.
14 (cstPPKFile)	The certificate store is the name of a file that contains a PPK (PuTTY Private Key).
15 (cstPPKBlob)	The certificate store is a string (binary) that contains a PPK (PuTTY Private Key).

22 (cstBCFKSBlob)	The certificate store is a string (binary or base64-encoded) representing a certificate store in BCFKS (Bouncy Castle FIPS Key Store) format. Note: this store type is only available in Java and .NET.
23 (cstPKCS11)	The certificate is present on a physical security key accessible via a PKCS11 interface. To use a security key the necessary data must first be collected using the CertMgr component. The ListStoreCertificates method may be called after setting CertStoreType to `cstPKCS11`, CertStorePassword to the PIN, and CertStore to the full path of the PKCS11 dll. The certificate information returned in the CertList event's `CertEncoded` parameter may be saved for later use. When using a certificate, pass the previously saved security key information as the SSLCertStore and set SSLCertStorePassword to the PIN. Code Example: SSH Authentication with Security Key `certmgr.CertStoreType = CertStoreTypes.cstPKCS11; certmgr.OnCertList += (s, e) => { secKeyBlob = e.CertEncoded; }; certmgr.CertStore = @"C:\Program Files\OpenSC Project\OpenSC\pkcs11\opensc-pkcs11.dll"; certmgr.CertStorePassword = "123456"; //PIN certmgr.ListStoreCertificates(); sftp.SSHCert = new Certificate(CertStoreTypes.cstPKCS11, secKeyBlob, "123456", "*"); sftp.SSHUser = "test"; sftp.SSHLogon("myhost", 22);`

Remarks

This is the subject of the certificate used for client authentication.

This property must be set after all other certificate properites are set. When this property is set, a search is performed in the current certificate store certificate with matching subject.

If a matching certificate is found, the property is set to the full subject of the matching certificate.

If an exact match is not found, the store is searched for subjects containing the value of the property.

If a match is still not found, the property is set to an empty string, and no certificate is selected.

The special value "*" picks a random certificate in the certificate store.

The certificate subject is a comma separated list of distinguished name fields and values. For instance "CN=www.server.com, OU=test, C=US, E=support@nsoftware.com". Common fields and their meanings are displayed below.


Field	Meaning
CN	Common Name. This is commonly a host name like www.server.com.
O	Organization

__property TiqbQBConnectorSSLProviders SSLProvider = { read=FSSLProvider, write=FSetSSLProvider };

enum TiqbQBConnectorSSLProviders {
  sslpAutomatic=0,
  sslpPlatform=1,
  sslpInternal=2
};

Default Value

sslpAutomatic

Remarks

This property specifies the SSL/TLS implementation to use. In most cases the default value of 0 (Automatic) is recommended and should not be changed. When set to 0 (Automatic) the component will select whether to use the platform implementation or the internal implementation depending on the operating system as well as the TLS version being used.

Possible values are:


0 (sslpAutomatic - default)	Automatically selects the appropriate implementation.
1 (sslpPlatform)	Uses the platform/system implementation.
2 (sslpInternal)	Uses the internal implementation.

Additional Notes

In most cases using the default value (Automatic) is recommended. The component will select a provider depending on the current platform.

When Automatic is selected the platform implementation is used by default. When TLS 1.3 is enabled via SSLEnabledProtocols the internal implementation is used.

Data Type

Integer

Timeout Property (QBConnector Component)

An initial timeout value to be used by incoming connections.

Syntax

__property int Timeout = { read=FTimeout, write=FSetTimeout };

Default Value

Remarks

Timeout is used by the component to set the operational timeout value of all inbound connections once they are established.

The default value is 30 seconds.

Data Type

Integer

AddUser Method (QBConnector Component)

Adds a new user to the AuthorizedUsers collection.

Syntax

void __fastcall AddUser(String User, String Password, String QBConnectionString, int AuthMode);

Remarks

Please refer to the AuthorizedUsers collection for more information.

User specifies the user which will be allowed to connect.

Password specifies the password of the user. This is not applicable when AuthMode is set to 1 (amWindows).

QBConnectionString sets the connection properties for the user. See AuthorizedUserQBConnectionString for details.

AuthMode defines how the user will be authenticated. There are two ways that the user may be authorized, against the user list defined in the component, or as a Windows user. From the client side the process of connecting is exactly the same no matter which option you choose. Possible values are:


0 (amNormal - default)	The user is authenticated against the user list defined in the component.
1 (amWindows)	The user is authenticated as a Windows user.

When using the amNormal AuthMode (default) the user's password will be checked against the Password property.

When using the amWindows AuthMode the component will validate the user's credentials with Windows. When calling AddUser the Password parameter should be set to empty string.

Config Method (QBConnector Component)

Sets or retrieves a configuration setting.

Syntax

String __fastcall Config(String ConfigurationString);

Remarks

Config is a generic method available in every component. It is used to set and retrieve configuration settings for the component.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the component, access to these internal properties is provided through the Config method.

To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.

DoEvents Method (QBConnector Component)

Processes events from the internal message queue.

Syntax

void __fastcall DoEvents();

Remarks

When DoEvents is called, the component processes any available events. If no events are available, it waits for a preset period of time, and then returns.

Reset Method (QBConnector Component)

Clears all properties to their default values.

Syntax

void __fastcall Reset();

Remarks

This method clears all properties to their default values.

Shutdown Method (QBConnector Component)

Shutdown the server.

Syntax

void __fastcall Shutdown();

Remarks

When this method is called, the component will stop Listening, break all active connections, and disconnect from QuickBooks.

Authorization Event (QBConnector Component)

Fired when the client presents its credentials to the server.

Syntax

typedef struct {
  int ConnectionId;
  int UserIndex;
  String User;
  String Password;
  bool Accept;
} TiqbQBConnectorAuthorizationEventParams;
typedef void __fastcall (__closure *TiqbQBConnectorAuthorizationEvent)(System::TObject* Sender, TiqbQBConnectorAuthorizationEventParams *e);
__property TiqbQBConnectorAuthorizationEvent OnAuthorization = { read=FOnAuthorization, write=FOnAuthorization };

Remarks

This is where the server can decide whether to continue or not, based on the supplied User and Password.

To accept or reject a connection set Accept to True of False.

The Accept parameter defaults to True if User is found in the AuthorizedUsers collection and Password matches, and False otherwise. The UserIndex parameter indicates the index at which the authorized user was found in the collection.

A UserIndex of -1 means that no matching credentials were found in the AuthorizedUsers collection.

Connected Event (QBConnector Component)

This event is fired immediately after a connection completes (or fails).

Syntax

typedef struct {
  int ConnectionId;
  int StatusCode;
  String Description;
} TiqbQBConnectorConnectedEventParams;
typedef void __fastcall (__closure *TiqbQBConnectorConnectedEvent)(System::TObject* Sender, TiqbQBConnectorConnectedEventParams *e);
__property TiqbQBConnectorConnectedEvent OnConnected = { read=FOnConnected, write=FOnConnected };

Remarks

If the connection is made normally, StatusCode is 0, and Description is "OK".

If the connection fails, StatusCode has the error code returned by the system. Description contains a description of this code. The value of StatusCode is equal to the value of the system error.

Please refer to the Error Codes section for more information.

ConnectionRequest Event (QBConnector Component)

This event is fired when a request for connection comes from a remote host.

Syntax

typedef struct {
  String Address;
  int Port;
  bool Accept;
} TiqbQBConnectorConnectionRequestEventParams;
typedef void __fastcall (__closure *TiqbQBConnectorConnectionRequestEvent)(System::TObject* Sender, TiqbQBConnectorConnectionRequestEventParams *e);
__property TiqbQBConnectorConnectionRequestEvent OnConnectionRequest = { read=FOnConnectionRequest, write=FOnConnectionRequest };

Remarks

This event indicates an incoming connection. The connection is accepted by default. Address and Port will contain information about the remote host requesting the inbound connection. If you want to refuse it, you can set the Accept parameter to False.

Disconnected Event (QBConnector Component)

This event is fired when a connection is closed.

Syntax

typedef struct {
  int ConnectionId;
  int StatusCode;
  String Description;
} TiqbQBConnectorDisconnectedEventParams;
typedef void __fastcall (__closure *TiqbQBConnectorDisconnectedEvent)(System::TObject* Sender, TiqbQBConnectorDisconnectedEventParams *e);
__property TiqbQBConnectorDisconnectedEvent OnDisconnected = { read=FOnDisconnected, write=FOnDisconnected };

Remarks

If the connection is broken normally, StatusCode is 0, and Description is "OK".

If the connection is broken for any other reason, StatusCode has the error code returned by the system. Description contains a description of this code. The value of StatusCode is equal to the value of the system error.

Please refer to the Error Codes section for more information.

Error Event (QBConnector Component)

This event fires information about errors during data delivery.

Syntax

typedef struct {
  int ConnectionId;
  int ErrorCode;
  String Description;
} TiqbQBConnectorErrorEventParams;
typedef void __fastcall (__closure *TiqbQBConnectorErrorEvent)(System::TObject* Sender, TiqbQBConnectorErrorEventParams *e);
__property TiqbQBConnectorErrorEvent OnError = { read=FOnError, write=FOnError };

Remarks

The Error event is fired in case of exceptional conditions during message processing. Normally, the component raises an exception.

ErrorCode contains an error code and Description contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the Error Codes section.

ConnectionId indicates the connection for which the error is applicable.

Header Event (QBConnector Component)

HTTP headers sent by the client.

Syntax

typedef struct {
  int ConnectionId;
  String Header;
  String Value;
} TiqbQBConnectorHeaderEventParams;
typedef void __fastcall (__closure *TiqbQBConnectorHeaderEvent)(System::TObject* Sender, TiqbQBConnectorHeaderEventParams *e);
__property TiqbQBConnectorHeaderEvent OnHeader = { read=FOnHeader, write=FOnHeader };

Remarks

When a client connects, this event will fire for each HTTP header received.

Request Event (QBConnector Component)

Fired when a client sends a request to the component.

Syntax

typedef struct {
  int ConnectionId;
  int UserIndex;
  String Request;
} TiqbQBConnectorRequestEventParams;
typedef void __fastcall (__closure *TiqbQBConnectorRequestEvent)(System::TObject* Sender, TiqbQBConnectorRequestEventParams *e);
__property TiqbQBConnectorRequestEvent OnRequest = { read=FOnRequest, write=FOnRequest };

Remarks

This event will fire with the raw XML data received from the client, which is to be processed by QuickBooks.

The ConnectionId indicates which client connection this Request event is firing for. The UserIndex is the index of the user in the AuthorizedUser array property. Request is the QBXML Request sent from the client.

A UserIndex of -1 means that no matching credentials were found in the AuthorizedUsers collection.

Response Event (QBConnector Component)

Fired when the component sends a response to the client.

Syntax

typedef struct {
  int ConnectionId;
  int UserIndex;
  String Response;
} TiqbQBConnectorResponseEventParams;
typedef void __fastcall (__closure *TiqbQBConnectorResponseEvent)(System::TObject* Sender, TiqbQBConnectorResponseEventParams *e);
__property TiqbQBConnectorResponseEvent OnResponse = { read=FOnResponse, write=FOnResponse };

Remarks

This event will fire with the raw XML retrieved from QuickBooks and sent to the client.

The ConnectionId indicates which client connection this Request event is firing for. The UserIndex is the index of the user in the AuthorizedUser array property. Response is the QBXML Response from QuickBooks, which is being transmitted back to the client.

A UserIndex of -1 means that no matching credentials were found in the AuthorizedUsers collection.

SSLClientAuthentication Event (QBConnector Component)

This event is fired when the client presents its credentials to the server.

Syntax

typedef struct {
  int ConnectionId;
  String CertEncoded;
  DynamicArray<Byte> CertEncodedB;
  String CertSubject;
  String CertIssuer;
  String Status;
  bool Accept;
} TiqbQBConnectorSSLClientAuthenticationEventParams;
typedef void __fastcall (__closure *TiqbQBConnectorSSLClientAuthenticationEvent)(System::TObject* Sender, TiqbQBConnectorSSLClientAuthenticationEventParams *e);
__property TiqbQBConnectorSSLClientAuthenticationEvent OnSSLClientAuthentication = { read=FOnSSLClientAuthentication, write=FOnSSLClientAuthentication };

Remarks

This event enables the server to decide whether or not to continue. The Accept parameter is a recommendation on whether to continue or to close the connection. This is just a suggestion: application software must use its own logic to determine whether or not to continue.

When Accept is False, Status shows why the verification failed (otherwise, Status contains the string "OK").

SSLConnectionRequest Event (QBConnector Component)

This event fires when a Secure Sockets Layer (SSL) connection is requested.

Syntax

typedef struct {
  int ConnectionId;
  String SupportedCipherSuites;
  String SupportedSignatureAlgs;
  int CertStoreType;
  String CertStore;
  String CertPassword;
  String CertSubject;
} TiqbQBConnectorSSLConnectionRequestEventParams;
typedef void __fastcall (__closure *TiqbQBConnectorSSLConnectionRequestEvent)(System::TObject* Sender, TiqbQBConnectorSSLConnectionRequestEventParams *e);
__property TiqbQBConnectorSSLConnectionRequestEvent OnSSLConnectionRequest = { read=FOnSSLConnectionRequest, write=FOnSSLConnectionRequest };

Remarks

This event fires when an SSL connection is requested and SSLProvider is set to Internal. This event provides an opportunity to select an alternative certificate to the connecting client. This event does not fire when SSLProvider is set to Platform.

This event allows the component to be configured to use both RSA and ECDSA certificates depending on the connecting client's capabilities.

ConnectionId is the connection Id of the client requesting the connection.

SupportedCipherSuites is a comma-separated list of cipher suites that the client supports.

SupportedSignatureAlgs is a comma-separated list of certificate signature algorithms that the client supports.

CertStoreType is the store type of the alternate certificate to use for this connection. The component supports both public and private keys in a variety of formats. When the cstAuto value is used the component will automatically determine the type. This property can take one of the following values:


0 (cstUser - default)	For Windows, this specifies that the certificate store is a certificate store owned by the current user. Note: this store type is not available in Java.
1 (cstMachine)	For Windows, this specifies that the certificate store is a machine store. Note: this store type is not available in Java.
2 (cstPFXFile)	The certificate store is the name of a PFX (PKCS12) file containing certificates.
3 (cstPFXBlob)	The certificate store is a string (binary or base64-encoded) representing a certificate store in PFX (PKCS12) format.
4 (cstJKSFile)	The certificate store is the name of a Java Key Store (JKS) file containing certificates. Note: this store type is only available in Java.
5 (cstJKSBlob)	The certificate store is a string (binary or base64-encoded) representing a certificate store in Java Key Store (JKS) format. Note: this store type is only available in Java.
6 (cstPEMKeyFile)	The certificate store is the name of a PEM-encoded file that contains a private key and an optional certificate.
7 (cstPEMKeyBlob)	The certificate store is a string (binary or base64-encoded) that contains a private key and an optional certificate.
8 (cstPublicKeyFile)	The certificate store is the name of a file that contains a PEM- or DER-encoded public key certificate.
9 (cstPublicKeyBlob)	The certificate store is a string (binary or base64-encoded) that contains a PEM- or DER-encoded public key certificate.
10 (cstSSHPublicKeyBlob)	The certificate store is a string (binary or base64-encoded) that contains an SSH-style public key.
11 (cstP7BFile)	The certificate store is the name of a PKCS7 file containing certificates.
12 (cstP7BBlob)	The certificate store is a string (binary) representing a certificate store in PKCS7 format.
13 (cstSSHPublicKeyFile)	The certificate store is the name of a file that contains an SSH-style public key.
14 (cstPPKFile)	The certificate store is the name of a file that contains a PPK (PuTTY Private Key).
15 (cstPPKBlob)	The certificate store is a string (binary) that contains a PPK (PuTTY Private Key).
16 (cstXMLFile)	The certificate store is the name of a file that contains a certificate in XML format.
17 (cstXMLBlob)	The certificate store is a string that contains a certificate in XML format.
18 (cstJWKFile)	The certificate store is the name of a file that contains a JWK (JSON Web Key).
19 (cstJWKBlob)	The certificate store is a string that contains a JWK (JSON Web Key).
21 (cstBCFKSFile)	The certificate store is the name of a file that contains a BCFKS (Bouncy Castle FIPS Key Store). Note: this store type is only available in Java and .NET.
22 (cstBCFKSBlob)	The certificate store is a string (binary or base64-encoded) representing a certificate store in BCFKS (Bouncy Castle FIPS Key Store) format. Note: this store type is only available in Java and .NET.
23 (cstPKCS11)	The certificate is present on a physical security key accessible via a PKCS11 interface. To use a security key the necessary data must first be collected using the CertMgr component. The ListStoreCertificates method may be called after setting CertStoreType to `cstPKCS11`, CertStorePassword to the PIN, and CertStore to the full path of the PKCS11 dll. The certificate information returned in the CertList event's `CertEncoded` parameter may be saved for later use. When using a certificate, pass the previously saved security key information as the and set to the PIN. Code Example: SSH Authentication with Security Key `certmgr.CertStoreType = CertStoreTypes.cstPKCS11; certmgr.OnCertList += (s, e) => { secKeyBlob = e.CertEncoded; }; certmgr.CertStore = @"C:\Program Files\OpenSC Project\OpenSC\pkcs11\opensc-pkcs11.dll"; certmgr.CertStorePassword = "123456"; //PIN certmgr.ListStoreCertificates(); sftp.SSHCert = new Certificate(CertStoreTypes.cstPKCS11, secKeyBlob, "123456", "*"); sftp.SSHUser = "test"; sftp.SSHLogon("myhost", 22);`
99 (cstAuto)	The store type is automatically detected from the input data. This setting may be used with both public and private keys and can detect any of the supported formats automatically.

CertStore is the store name or location of the alternate certificate to use for this connection.

Designations of certificate stores are platform-dependent.

The following are designations of the most common User and Machine certificate stores in Windows:


MY	A certificate store holding personal certificates with their associated private keys.
CA	Certifying authority certificates.
ROOT	Root certificates.

CertPassword is the password of the certificate store containing the alternate certificate to use for this connection.

CertSubject is the subject of the alternate certificate to use for this connection.

The special value * matches any subject and will select the first certificate in the store. The certificate subject is a comma separated list of distinguished name fields and values. For instance "CN=www.server.com, OU=test, C=US, E=support@nsoftware.com". Common fields and their meanings are displayed below.


Field	Meaning
CN	Common Name. This is commonly a host name like www.server.com.
O	Organization
OU	Organizational Unit
L	Locality
S	State
C	Country
E	Email Address

If a field value contains a comma it must be quoted.

SSLStatus Event (QBConnector Component)

This event is fired to show the progress of the secure connection.

Syntax

typedef struct {
  int ConnectionId;
  String Message;
} TiqbQBConnectorSSLStatusEventParams;
typedef void __fastcall (__closure *TiqbQBConnectorSSLStatusEvent)(System::TObject* Sender, TiqbQBConnectorSSLStatusEventParams *e);
__property TiqbQBConnectorSSLStatusEvent OnSSLStatus = { read=FOnSSLStatus, write=FOnSSLStatus };

Remarks

The event is fired for informational and logging purposes only. It is used to track the progress of the connection.

Status Event (QBConnector Component)

Shows the status of the server as clients connect and transactions are made.

Syntax

typedef struct {
  int ConnectionId;
  String Message;
} TiqbQBConnectorStatusEventParams;
typedef void __fastcall (__closure *TiqbQBConnectorStatusEvent)(System::TObject* Sender, TiqbQBConnectorStatusEventParams *e);
__property TiqbQBConnectorStatusEvent OnStatus = { read=FOnStatus, write=FOnStatus };

Remarks

The event is fired for informational and logging purposes only.

Config Settings (QBConnector Component)

The component accepts one or more of the following configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the component, access to these internal properties is provided through the Config method.

QBConnector Config Settings

AuthFlags: Auth Flags to use when connecting to QuickBooks.

This configuration setting controls what auth flags are sent to QuickBooks. The default value is 0 (no auth flags set).

ConnectedToQB: Used to connect or disconnect from QuickBooks.

This setting allows you to connect and disconnect to the QuickBooks request processor which resides on the server machine. Calling Config with ConnectedToQB=False will immediately disconnect from QuickBooks. ConnectedToQB=True, however, will use the DefaultConnectionString (if present) to open a persistent connection to QuickBooks. Note that if the component is already connected to QuickBooks, setting ConnectedToQB to True will cause the component to raises an exception. Connecting in this manner is only useful if there are no connection strings specified in any AuthorizedUsers, as in that case the component will disconnect from QuickBooks and reconnect with the credentials specified for that individual user. However, it is not necessary to use this configuration setting to connect to QuickBooks. If no connection strings are specified in the AuthorizedUsers and the component is not currently connected to QuickBooks, a new connection will be made using the DefaultConnectionString.

DefaultConnectionString: Default connection string to use for users not in the AuthorizedUsers collection.

If a user connects to the component who is not in the AuthorizedUsers collection, and you set the Accept parameter in the Authorization event to True anyways, the component will use this connection string to open a connection with QuickBooks. This is blank by default.

ReadOnly[i]: Whether a user is restricted to read-only access.

This setting specifies whether a user is limited to read-only access. The index should be the of the user in the AuthorizedUsers collection. For instance: QBConnector1.Config("ReadOnly[0]=True"); This indicates that the first user is limited to read-only access. The default value is False (full access).

UseInteractiveLogon: Whether interactive or network logon is used when AuthMode is set to Windows.

This setting only applies when the AuthorizedAuthMode is set to 1 (amWindows). When performing windows authentication a regular network logon is attempted by default. When this setting is set to true an interactive logon is performed instead. This setting may be required in certain circumstances, such as using a domain account and the domain controller is Samba.

Base Config Settings

BuildInfo: Information about the product's build.

When queried, this setting will return a string containing information about the product's build.

CodePage: The system code page used for Unicode to Multibyte translations.

The default code page is Unicode UTF-8 (65001).

LicenseInfo: Information about the current license.

When queried, this setting will return a string containing information about the license this instance of a component is using. It will return the following information:

Product: The product the license is for.
Product Key: The key the license was generated from.
License Source: Where the license was found (e.g., RuntimeLicense, License File).
License Type: The type of license installed (e.g., Royalty Free, Single Server).
Last Valid Build: The last valid build number for which the license will work.

MaskSensitive: Whether sensitive data is masked in log messages.

In certain circumstances it may be beneficial to mask sensitive data, like passwords, in log messages. Set this to true to mask sensitive data. The default is true.

This setting only works on these components: AS3Receiver, AS3Sender, Atom, Client(3DS), FTP, FTPServer, IMAP, OFTPClient, SSHClient, SCP, Server(3DS), Sexec, SFTP, SFTPServer, SSHServer, TCPClient, TCPServer.

UseInternalSecurityAPI: Tells the component whether or not to use the system security libraries or an internal implementation.

When set to false, the component will use the system security libraries by default to perform cryptographic functions where applicable.

Setting this setting to true tells the component to use the internal implementation instead of using the system security libraries.

This setting is set to false by default on all platforms.
