Suspend/Pause Application

I have a vb6 app that needs to suspend/pause another application currently running. Is there a way to handle this using the windows api or other method?

Thanks in advance for the assistance.

I am not sure if you can pause an application process because it consists of several threads, but you can pause a thread, and resume it. I suppose you need to do following:

1. Enumerate running processes to find process you are looking for by its name
2. Find process ID of that process
3. Enumerate all threads related to that process ID
- Open threads to obtain thread handle
- You must open thread with specific access rights that allow you to pause it
4. Pause threads one by one
5. Resume paused threads
6. Close all open handles :)

You could start with examining this:

Here is some explanation how to enumerate threads:
