Here the code I use for ShellExecute

   DECLARE INTEGER ShellExecute IN SHELL32.DLL INTEGER nWinHandle,;
                                               STRING cOperation,;
                                               STRING cFileName,;
                                               STRING cParameters,;
                                               STRING cDirectory,;
                                               INTEGER nShowWindow
    result = ShellExecute(hWnd, "open", cExtention, cParams, cFolder, 5)
    DO CASE
       CASE result ==  0         && The system is out of memory or resources.
            msg = "The system is out of memory or resources."
       CASE result ==  2         && Bad Association (for example, invalid URL)
            msg = "invalid URL"
       CASE result == 29         && Failure to load application
            msg = "Fail to load application"
       CASE result == 30         && Application is busy 
            msg = "Application is busy"
       CASE result == 31         && No application association
            msg = "No application association"
   ENDCASE
   IF INLIST(result, 0, 2, 29, 30, 31)
      MessageBox(msg, 0 + 64, "Error")
   ENDIF
