I´m working with various *.rc files in the same project. When you create anIDC_ or IDD_ or IDI_ or IDB_ number for resources and dialogs, Visual repeat frequently the same number. Is possible to change the number of the new resource at the end of resource.h file, but it´s very laborious if u work with a lot of controls and dialogs. Is an esay way for take the control of these numbers. What kind of problems colud i have if some resources have the same numbers? Thanks.
