Changing a Symbol or Symbol Name
When you create a new resource or resource object, the development environment assigns it a default name, for example, IDD_DIALOG1. Use the resource’s property page to change the default symbol name or to change the name of any symbol already associated with a resource.
To change a resource’s symbol name
In ResourceView, select the resource.
From the View menu, choose Properties to move directly to the resource’s property page.
In the ID box, type a new symbol name or select from the list of existing symbols. If you type a new symbol name, it is automatically assigned a value.
You can use the Resource Symbols browser to change the names of symbols not currently assigned to a resource. For more information, see Changing Unassigned Symbols.
