how to update or refresh the menu?

[tamsel]

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.

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

[tamsel]

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? This MFC all day long. And I see you've tried the updateui mechanism.

[tamsel]

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

[Roger Allen]

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

[kirants]

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

[tamsel]

kirants , i wll surely follow that.

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