To prevent Smart Minimize and OK buttons from appearing on title bar of dialog boxes

1. Manually edit the resource (.rc) file for the dialog box. Add WS_NONAVDONEBUTTON
   
   to the STYLE
   line to prevent the display of the Smart Minimize
   button, as shown:

   //
   
   // Dialog.
   
   //
   
   IDD_WIZARD DIALOG DISCARDABLE 0, 0, 140, 57
   
   STYLE WS_POPUP | WS_CAPTION | WS_NONAVDONEBUTTON
   
   
   EXSTYLE 0x80000000L
   
   CAPTION "Your Wizard"

2. Remove SHDIF_DONEBUTTON
   from the dwFlags
   member of the SHINITDLGINFO
   user interface structure (generally found in the WM_INITDIALOG
   message handler for the dialog box) to remove the OK
   button from the title bar, as follows:

   SHINITDLGINFO shidi;
   
   switch (message)
   
   {
   
       case WM_INITDIALOG:
   
           shidi.dwMask = SHIDIM_FLAGS;
   shidi.dwFlags = SHIDIF_SIZEDLGFULLSCREEN;
   
   
           shidi.hDlg = hDlg;
   
           if (!SHInitDialog(&shidi)) {
   
               MessageBox(NULL, _T("Can't create dialog box."),
   
                          _T("Error"), MB_OK);
   
               exit(0);  // Replace with specific error handling.
   
           }
   
           .
   
           .
   
           .

3. Add a call to the SHDoneButton
   function with the SHDB_HIDE
   state after calling the SHInitDialog
   function to hide the OK
   button, as follows:

   if (!SHDoneButton(hDlg, SHDB_HIDE)) {
   
           MessageBox(NULL, _T("Can't hide the OK button."),
   
                      _T("Error"), MB_OK);
   
           exit(0);  // Replace with specific error handling.
   
       }

4. If you run the code as is, no Smart Minimize
   button or OK
   button appears on the title bar, but tapping the Enter
   key in the emulator or on the input panel keyboard closes the dialog
   box. If this is not the desired behavior, make the appropriate changes
   to the WM_COMMAND
   message handler. Generally, you want to set focus to the default control in the current panel of your wizard.
