how to update or refresh the menu?

how to update or refresh the menu when its text is changed . i used getmenustring() using that i got the string and using modifymenu() it modified my required menu. but the problem is after modification, its overwrites there and not changing . only solution is to update or refresh the menu.

thanks

Why aren't you using the MFC's updateui mechanism?

i am using win32 project. in that only i have to do.

hmm, in this case do post the cose you are using for updating the menu and tell us where you are doing it.

And how is this a Win32 app? :D This MFC all day long. And I see you've tried the updateui mechanism.

padex ,


all are handled by my, i created MFC application in win32 application. everything was hand written by me, thats only certain things such as control variable is not available here

If your updating a menu which is currenty selected into a window you need to call DrawMenuBar(HWND) to cause it to refresh.

tamsel, please use code tags properly. See my signature below on how to use. Please use Testing area to experiment

kirants , i wll surely follow that.

but that drawmenubar() is not repainting the menu. where that DrawMenuBar() can be called?
