This feature is useful for debugging Plugins and ActiveX components.

Ensure the COM component is built with debug information.


Create a Script for the Package.


In the 'Debug | Platform' page, you can select to either attach to an unmanaged process or specify the path to an unmanaged application to call your managed code.


Add breakpoints in the source code to debug.

Attach to an Unmanaged Process

If you are using:

  • An In-Process COM server, attach to the client process
  • A Local COM Server, attach to the server process

Click on the Debug window Run button (or press F6) to display a list of processes from which you can choose.
