I need to do the following: Application AppA is run by user UserA Now

  • 0

I need to do the following:

  • Application “AppA” is run by user “UserA”
  • Now AppA starts AppB using the runas-command (it is started as UserB)

Is it now possible to let AppA control AppB via COM? While everything works fine without the different user accounts, I can’t seem to get the COM object in the case mentioned above.

By the way: I use Runtime.InteropServices.Marshal.GetActiveObject to get the COM object of AppB.

Any ideas?
Thanks!

    I think you need to set the DCOM Security on the called COM Object. There is an example here:

    1. Given the ProgId
    2. Find the DCOM Configuration in Component Services and get to the properties
    3. Find the Security Tab and set the Launch and Activation Permissions, and give the caller the rights to do this.
