Add this class to your project and after designing the layout of your standard menu, use search and replace to replace 'System.Windows.Forms.MenuItem' with 'MenuItemEx'. You will then be able to assign colors and icons to each menu item in the project. Use this class for MDI projects or download the MenuSkinner component in the Controls section. The MenuSkinner is much simpler to use but there is a problem with Menus that unMerge which I have yet to find a solution for.
