Does ShellExecute run in separate thread?

How can I wait for ShellExecute command. I believe that it spawns a thread.
Is there any way to synchronize that?

    Use ShellExecuteEx() or CreateProcess() { +WaitForSingleObject() } if
you want to wait on the process that it runs.

My own preference is to put that WaitForSingleObject in a separate thread, which leaves
the GUI alive while the process runs. For example

/* static */ UINT CMyView::WaitForProcess(LPVOID p)
      MyProcessInfo * info = (MyProcessInfo *)p;
      ::WaitForSingleObject(info->process, INFINITE);
      info->wnd->PostMessage(UWM_PROCESS_FINISHED, (WPARAM)info->process);
      delete info;

class MyProcessInfo { 
         MyProcessInfo(CWnd * w, HANDLE h) { wnd = w; process = h; }
         CWnd * wnd;
         HANDLE process;

MyProcessInfo * info = new ProcessInfo(this, shellinfo.hProcess);
AfxBeginThread(WaitForProcess, info);
ProcessRunning = TRUE;


    ProcessRunning = TRUE;
    return 0;

// For those menu items you want to disable while the process is running, e.g.,
// the RunProcess menu item (whatever you call it)
void CMyView::OnUpdateRunProcess(CCmdUI * pCmdUI)

Outlook runs in the background
When I get in Outlook to check e-mail and then get out of Outlook, I have to completely reboot the computer before I can get back in Outlook. When I am shutting down, I get a screen that more or less says that Outlook is running in the background (although it doesn't show when I do Ctrl-Alt-Del). We have reinstalled Outlook, but it still hasn't helped. In Task Manager, on the Processes tab, do you see any instances on Outlook.exe or MAPISP32.EXE when this happens?

VB6 service under Server 2008 can't run another VB application
