an C# exe with no src code,now i want to disable some menuItems with APIs.

like this:

HMENU hMenu = (HMENU) PostMessage(hWnd, MN_GETHMENU, 0, 0);

EnableMenuItem(hMenu,uIdEnableMenultem,MF_DISABLED); ...

but it's not work for C# exe.What should I do?

If the application is using the standard WinFroms menus then your technique won't work !

Those menus are not the typical WIN32 menus that respond to these APIs so you will have use

Reflection, decompilation, or any other way to modify the property "Enabled" of that menu Item to FALSE.
