Method Detail
Function | CCpfcAsyncConnection.Connect | (Display as String [optional], UserID as String [optional], TextPath as String [optional], TimeoutSec as Long [optional]) as IpfcAsyncConnection |
Causes the application to connect to an existing Creo Parametric process running on a host using a specified display. It is intended for use in simple and full asynchronous modes.
If the method locates more than one Creo Parametric session with the appropriate characteristics, it will throw an IpfcXToolkitAmbiguous exception.
If you want to connect or reconnect to a specific Creo Parametric session, use the method IpfcAsyncConnection.ConnectById()
The application may only connect to one Creo Parametric session at any time.
Parameters:
Display
The name of the display Creo Parametric is using. If this is null, match any display. If this is an empty string, assume the local host.
UserID
The name of the user running the Creo Parametric to connect to. If this is null, match any user. If this is an empty string, assume the current user.
TextPath
The path under which the message and menu files are held. If no external messaging or menus are needed pass null.
TimeoutSec
The time, in seconds, to wait for Creo Parametric to respond to the connection request. Pass null to use the default connection timeout.
Returns:
Object representing the asynchronous connection.
Function | CCpfcAsyncConnection.ConnectById | (Id as IpfcConnectionId, TextPath as String [optional], TimeoutSec as Long [optional]) as IpfcAsyncConnection |
Connects to a specific Creo Parametric session by passing the identification string.
The ID string for a given session can be obtained from IpfcAsyncConnection.GetConnectionId().
The application may only connect to one Creo Parametric session at any time.
Parameters:
Id
The connection id string previously obtained for the Creo Parametric session you wish to connect to.
TextPath
The path under which the message and menu files are held. If no external messaging or menus are needed pass null.
TimeoutSec
The time, in seconds, to wait for Creo Parametric to respond to the connection request. Pass null to use the default timeout.
Returns:
Object representing the asynchronous connection.
Function | CCpfcAsyncConnection.ConnectWS | (Display as String [optional], UserID as String [optional], WSName as String [optional], TextPath as String [optional], TimeoutSec as Long [optional]) as IpfcAsyncConnection |
Causes the application to connect to an existing Creo Parametric process and to an existing Pro/INTRALINK worksapce running on a host using a specified display. For use in simple and full asynchronous modes.
NOTE: This method is deprecated. Pro/INTRALINK 3.4 is not supported. Please use IpfcAsyncConnection.Connect() to connect to an existing Creo Parametric process that has a Pro/INTRALINK 10.0 server registered.
If the method locates more than one Creo Parametric session with the appropriate characteristics, it will throw an IpfcXToolkitAmbiguous exception.
If you want to connect or reconnect to a specific Creo Parametric session, use the method IpfcAsyncConnection.ConnectById()
The application may only connect to one Creo Parametric session at any time.
Parameters:
Display
The name of the display Creo Parametric is using. If this is null, match any display. If this is an empty string, assume the local host.
UserID
The name of the user running the Creo Parametric to connect to. If this is NULL, match any user. If this is an empty string, assume the current user.
WSName
The name of the workspace Creo Parametric should use. If this is NULL, match any available workspace.
TextPath
The path under which the message and menu files are held. If no external messaging or menus are needed pass null.
TimeoutSec
The time, in seconds, to wait for Creo Parametric to respond to the connection request.
Returns:
Object representing the asynchronous connection.
Sub | Disconnect | (TimeoutSec as Long [optional]) |
Disconnects the application from the current Creo Parametric process. Creo Parametric will still be running after this call.
For J-Link only: In order to clear allocated Creo Parametric memory owned by the application, PTC recommends forcing garbage collection (using Java's System.gc()) before disconnecting from Creo Parametric.
Exceptions thrown (but not limited to):
IpfcXToolkitUnsupported - Connection is not Obtained
<reference to unknown entity pfcExceptions::XProeWasNotConnected> - Handle not initialized
Parameters:
TimeoutSec
The time, in seconds, to wait for Creo Parametric to respond to the disconnect request.
User Guide References:
Sub | End | () |
Terminates and disconnects from the current Creo Parametric process.
Sub | EventProcess | () |
Enables your process to respond to listener calls from Creo Parametric. You must call this function within your control loop in order that your application will be able to respond to listener calls. Creo Parametric will be blocked until the application responds to a registered listener.
Exceptions thrown (but not limited to):
IpfcXToolkitGeneralError - Creo Session has already terminated.
Function | ExecuteAsyncJavaMethod | (Class as String, Method as String, InputArguments as IpfcArguments, ClassForUnlock as String) as Boolean |
This is the "JOTK sandbox" to execute methods with full OTK Asynchronous Java access. Can be used only in Java language binding.
Before executing the supplied Java method, the sandbox checks that the application is unlocked. It performs no execution and returns false if this check fails, which may happen because either the application is not unlocked (and overriding developer licenses are not present), or the application jar was not found (for instance, due to a wrong ClassForUnlock argument).
Parameters:
Class
Method's class. Full class name including the package, in Java syntax.
Method
Method's name.
InputArguments
Method's input arguments.
ClassForUnlock
The class used for unlocking this Java application. Full class name including the package, in Java syntax.
Returns:
False if the check for unlocking failed.
Function | CCpfcAsyncConnection.GetActiveConnection |
Connection established between your application and Creo Parametric. If your application is connected with Creo Parametric, call this function to get the connection object.
Returns:
Object representing the asynchronous connection.
Function | GetConnectionId | () as IpfcConnectionId |
Extracts the identification handle of the current Creo Parametric process.
Format of identification string is the following.
"host:H:address_version:A:address_type:T:rpcnum:R:rpcversion:V:netaddr:N"
where H - host name where Creo Parametric runs A - address version T - address type R - RPC number V - RPC version N - net address. The identification string can be used in subsequent attmepts to connect to this Creo Parametric session by this application or any other Creo Parametric TOOLKIT or PFC-based application.
Exceptions thrown (but not limited to):
IpfcXToolkitUnsupported - Connection is not Obtained
Returns:
The connection identifier handle.

Sub | InterruptEventProcessing | () |
Call this function from within a Creo Parametric callback function to halt a loop currently running in IpfcAsyncConnection.WaitForEvents().
Function | IsRunning | () as Boolean |
Determines whether you are currently connected to an actively responding Creo Parametric session.
Returns:
true if communications with Creo Parametric are possible false otherwise.
User Guide References:
Function | CCpfcAsyncConnection.Start | (CmdLine as String, TextPath as String [optional]) as IpfcAsyncConnection |
Causes the application to spawn and connect to a new Creo Parametric session. For use in simple and full asynchronous modes.
Parameters:
CmdLine
The full path to the startup command, batch file or script file used to start Creo Parametric.
TextPath
The path under which the message and menu files are held. If no external messaging or menus are needed pass null.
Returns:
Object representing the asynchronous connection.
Sub | WaitForEvents | () |
Initiates an event loop which will call event processing periodically to handle events returned from Creo Parametric. Applicable only for full asynchronous applications which are not supposed to carry out any tasks while waiting for Creo Parametric events.
This function will not return until interrupted by IpfcAsyncConnection.InterruptEventProcessing() or an error. No separate application processing is possible until that time, except within Creo Parametric event callbacks.
