How do i change the Grayed portion of a menu. EG i have used AppendMenu to add it with the WM_STRING and the WM_GRAYED flags set. How do i remove the Grayed part so it is enabled again, without removing it and re-adding it?
Surely there is a way?

Take a look at this post© http://forums©vb-world©net/showthrea...threadid=55637
But it doesn't cover the Grayed or enabled part of it. It talks about the Checked state, which is fine. I wanna know about the Grayed state.
BW :cool:
You can make use of EnableMenuItem to enable and Gray a menu item© By the way, does anyone know how you can assign Keyboard Accelerator to a menu item?? For example, if you press Shift+Y, it will be like selecting the menu item©
Thanks
