How Add Passwd Setting In ScreenSaver App Using MFC?

Environment: VC++ 4.0/Win95

 I programed a screen saver with MFC.It is like the sample  of VC 4.0.
But ,when it runs,the passwd setting in Display ScreenSaver Dialog doesn't
take effect.That is to say,if I press the passwd button,there is nothing  to happen.
My program is programed as follows:

 CWinAppp have a screen window which derivered from Cwnd.
 The Cwnd is set  TOP_MOST and as large as the screen.
 In CwinApp::InitStance(),I first judge the command line argument.
 if argv[1]==_T("p"), then I create screen window as a child window for previdw.

  if argv[1]=_T('s"), then I create the normal screen  window.

 In the CSaverWnd::OnSyscommand(),if ((nID==SC_SCREENSAVE) || (nID==SC_CLOSE) then return;

 else call CWnd::onSysCommdand();

 The CSaverWnd also deal with other message,such as: WM_SETCURSOR, WM_NCACTIVATE,
WM_ACTIVATE,WM_ACTIVATEAPP,WM_MOUSEMOVE,WM_L/RBUTTONDOWN,WM_KEYDOWN,WM_SYSKEYDOWN.

my screen saver run right except there is no password protection.


I debuger it,and found if the password setting button is pressed,the argv[1]
became _T("a").How I can deal with it?

What anything else  I  dont do in CSaverWnd ?


 Help me!
Thanks a lot!
