You can use AfxGetThread()->m_nThreadID. You MUST make the call to AfxGetThread() from the thread whose ID you want.

Well, that one returns the thread and process IDs and not handles. Handles are not the same as IDs. Not sure what the user intends to do ...

Hi,


I am not using MFC in my application. And more over GetWindowThreadProcessId() function will return only the Thread ID and Process ID but I need to get the handle of the thread. I am having only the handle of the window. How to get the handle of the thread that created this window?

You could use OpenThread to get a thread handle, followed by CloseHandle to close the handle when you are done with the thread handle.

Hi,

I have to use my code in 98, me, nt, 2000, 2003 and XP. The API (openThread) you have specified is not supported in 98 and nt. Is there any other API that can be used for the same purpose.

Spy++ does it, so it should be possible.
