When you create dialogs at runtime, you specify—directly or indirectly—a resource ID and the dialog loads itself from that resource, which is embodied into your executable. That dialog can—and usually does—contain child controls. These child controls and some of their attributes (text, position, font, and so on) are contained in that resource and are automatically created at runtime. Thus, C++ and GUI can slowly get out of sync—simply using the Resource Editor and removing a control from a dialog can have disastrous effects if in your code you still assume that control exists.
