C / C++ / MFC

• we have a DIALOGEX resource.
  
• the dialog has attached a menu with ID in the .rc file (not a name).
  
• a CLASS statement was inserted in .rc file, that we'll replace with a class name with the same length.
  

WCHAR* pClassName = ((WCHAR*)lpDialogTemplate
                     // skip DLGTEMPLATEEX structure
                     + sizeof(DLGTEMPLATEEX) / sizeof(WCHAR)
                     // skip menu
                     + sizeof(WORD) / sizeof(WCHAR));

Are you sure your OnUpdateChartoptionsGrid handler is called by MFC?

isGrid = 0;	// assume isGrid is initialized to 0

isGrid = 1 - isGrid;	// isGrid is now 1 (1 - 0)
isGrid = 1 - isGrid;	// isGrid is now 0 (1 - 1)

isGrid = 1;	// assume isGrid is initialized to 1

isGrid = 1 - isGrid;	// isGrid is now 0 (1 - 1)
isGrid = 1 - isGrid;	// isGrid is now 1 (1 - 0)

Are you sure this function is executed when you start the program, open the dialog and click on menu item?

added the code to make the grid appear/disappear. Every thing is working fine. Only the check is not appearing.

did you do any research on this or are you just wanting other people to do your work?
