OK, The subject line says it all. I need to start a windows GUI program when my user clicks a button and wait for the GUI to return. I've been mucking around with ::system and I can get the GUI running but the ::system function returns immediately...

Any Help?

Good question, Ron! Try to do something like this:

STARTUPINFO info={sizeof(info)};
PROCESS_INFORMATION processInfo;
if (CreateProcess(path, cmd, NULL, NULL, TRUE, 0, NULL, NULL, &info, &processInfo))
{
    ::WaitForSingleObject(processInfo.hProcess, INFINITE);
    CloseHandle(processInfo.hProcess);
    CloseHandle(processInfo.hThread);
}

Good luck!
