There is one more way to do it. Make a dialog box with desired message. Create a thread, call DoModal() in this thread to display that dialog box. When u need to kill dialog, kill the thread. How's that??

Use events associated with the combo box.

Write CreateProcess(...) Note that 'C' and 'P' are capital.
