(OP)
How can I pause the execution of a parent process until the child process is completed? My dilemna is I want to execute an external program via ShellExecute and have the calling process wait until it is done before proceeding. The external program is called using a list of files generated in a listbox control and if I do not wait until the ShellExecute command is completed, my system gets bogged down with multiple instances of the external program.

RE: C++ Threads

static STARTUPINFO si;    static PROCESS_INFORMATION pi;

    memset(&si,0,sizeof(si));
    memset(&pi,0,sizeof(pi));
    si.cb = sizeof(si);
    si.wShowWindow=uCmdShow;

    CreateProcess(
        NULL,           // pointer to name of executable module
        lpCmdLine,      // pointer to command line string
        NULL,           // pointer to process security attributes
        NULL,           // pointer to thread security attributes
        FALSE,          // handle inheritance flag
        NULL,           // creation flags
        NULL,           // pointer to new environment block
        NULL,           // pointer to current directory name
        &si,            // pointer to STARTUPINFO
        &pi             // pointer to PROCESS_INFORMATION
        );

   WaitForInputIdle(pi.hProcess, 6000);
