Connecting to different instances of Mathcad prime 4

[pklemm-2]

I am using Mathcad Prime SDK 3.1 for Mathcad Prime 4 to automate some time consuming calculations and worksheet management. As described in SDK, the communication is done over an

ApplicationCreatorClass() call. This works more ore less fine but I cannot control to which running Mathcad instance the link will be performed. My question is: Is there any way to establish connections to different  Mathcad instances running on the same computer?

Is there any way you can get the process ID number (PID) of the application instance that you are connecting/ connected to?

Yes. I can get PIDs of all running instances with

System.Diagnostics.Process.GetProcesses().

I tried another way with OLE32.dll:

Reading out the ROT (running object table) with the IMoniker interface, as it is described for EXCEL connection. After getting a running COM object instance the .Net interface or class must be known like here:

if (lComObject is Microsoft.Office.Interop.Excel.Workbook)

{

Microsoft.Office.Interop.Excel.Workbook lExcelWorkbook = (Microsoft.Office.Interop.Excel.Workbook)lComObject;

...

}

I tried to substitude "Microsoft.Office.Interop.Excel.Workbook" with the automation interface class of Mathcad and also with its Application class but there was no match.

Hello LucMeekes,

excuse me that I ask you directly, but there is nobody here who has experiences in that except You.

I am always looking for the solution of connecting to different instances of mathcad.
Do you have any more suggestions for me?
