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?
Yes. I can get PIDs of all running instances with
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.
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?
