I thought that but honestly didn't try.
I'm having difficulty understanding threads. It should mean an app (no?). Collecting thread and process ids I get same values for multiple instances of apps - like word (CreateProcess and RunAndWait samples note this).
I'll try EnumThreadWindows. Thanks.

>Cetin,
>Since you are working with FLLs and such, you may be able to implement EnumThreadWindows (it requires a callback function). This will give you the handle to all windows assocaited with the thread. If you use CreateProcess to create the process, the PROCESS_INFORMATION structure is filled with the thread ID to use with this function.
