Hi everyone

I want to avoid a dialog derived from CExtResizablePropertySheet from being resized, I have tried to modify the dialog style, removing the WS_THICKFRAME style, but it seems the framework doesn’t allow changing this properties. How can I make a CExtResizablePropertySheet  non resizable? When I create a resource for a normal dialog, and derive the class from CExtResizableDialog the library keeps the styles selected for it, but it’s not the same for the CExtResizablePropertySheet.

Thanks in advance

Dear Sergio,

You should use your own class derived from CExtResizablePropertySheet and override its WindowProc virtual method like this:

 virtual LRESULT WindowProc(
  UINT message,
  WPARAM wParam,
  LPARAM lParam
  ) 
 {
  if( message == WM_NCHITTEST )
  {
   LRESULT lResult = 
       CExtWSBase::WindowProc(message,wParam,lParam);
   if( lResult == HTBORDER
       || lResult == HTBOTTOM
       || lResult == HTBOTTOMLEFT
       || lResult == HTBOTTOMRIGHT
       || lResult == HTLEFT
       || lResult == HTRIGHT
       || lResult == HTTOP
       || lResult == HTTOPLEFT
       || lResult == HTTOPRIGHT
     )
     return HTNOWHERE;
   return lResult;
  }
  return CExtWSBase::WindowProc(message,wParam,lParam);
 }
