The problem is when I draw in the DGN. It always draws in the first opened instance of MicroStation

You're using COM to start an executable (MicroStation).  One of the drawbacks of COM (20^th century technology) is that it can't differentiate between running executables.  You must find another way to identify each instance of MicroStation.   As a Windows programmer you can use system features of C++ (Win32) or .NET. As I advised already, consult Microsoft web sites to find how to get a reference to a specific instance of a running process.

Don't use COM, because it leads to the problem you describe.  Instead, design an in-process app or macro that you can invoke with a MicroStation key-in (e.g. macro run HarpreetVba or mdl load HarpreetSingh).  Then you can invoke the appropriate key-in from each MicroStation process.

Thanks Jon,

This is what I wanted to understand. I understood it is a limitation and I need to find out some other solution.

Thanks
