Sends SAM_CreateComplete to windows with contents (top-level windows and child table windows) after creating the window's children and displaying the window (and its children). For example, suppose you create a form window with a data field and a child table window. The child table window has one column. The following happens: 1. The form window is created. 2. The data field is created. 3. The child table window is created. 4. The child table window's column is created. Once all this is done, sends a SAM_Create message to the top-level window and all of its children. Next, makes the form window and its children visible. Finally, sends a SAM_CreateComplete message to the child table window, and then to the form window (the top-level window). By processing the SAM_CreateComplete message, you can do initialization tasks that depend on the state or contents of child windows. You can also use SAM_CreateComplete to wait to do initialization t
