Windows Resource Files

You should place every element of the user interface that needs to be localized in a Windows resource file, including pictures, strings, messages, menus, dialog boxes, and version information. The table below lists the individual resource elements defined by Windows.

As you can see in Figure 4-4 below, Visual C++ 2 presents you with a categorized list of all elements contained in your resource file. To add a menu, string, or other item, click on the appropriate category, create a new identifier, and assign it a value and type. The tool automatically fills in the rest of the resource file format. To see what the complete resource file format looks like, open your .RC file in a simple text editor.
