Problem in Threads

Hi I created a thread which spawns a application. the spawn is no wait, and i want to get when the thread is quit. I dont want to use a loop to check the status(for STILL_ACTIVE). is there a way to check the thread is ended?
It is urgent , can anybosy help me?

Use ShellExecuteEx()

wait for the process' handle in a thread and that's all

Sally

use WaitForSingleObject(threadHandle, ...)
