Unfortunately, ShellExecute() doesn't provide a mechanism for this. You have several options:

(1) Use CreateProcess() and monitor the process handle for completion. This is what I do in API_APPRUN (download from the Files Section)

(2) Use ShellExecuteEx(), extract the process handle from the returned structure, and use the same basic process to monitor the process completion I use in API_APPRUN

(3) Instantiate the WSH Wscript.Shell object and use it's RUN method. It provides an option to wait on termination.
