How to know if a window handle created by procees

I am creating a process using CreateProcess method.
How can i know if it creates a window handle or not?

Man! This problem was discussed yesterday in your previous thread :eek:

Please dont misunderstand me.....

When we create a process, we may open an application which might have a handle and which might not have a handle also.
My question is how to know if the created application has a window or not

I don't know any way other than enumerating all windows and check the process ID they were created by.

Like Victor said, use EnumThreadWindows().
