SAM_Create is sent to a top-level window (dialog box, form window, or table window) and then to all of its children after they are created, but before they are made visible. It is also sent to an MDI window. For example, follow these steps to create a form window that has data fields: 1. Create the form window. 2. Create each of its data fields. After creates all the windows, but before making them visible, sends SAM_Create to the objects in this order: 1. The form window. 2. Each of the form's data fields. After sends the SAM_Create messages, makes the form window and data fields visible. By processing the SAM_Create message, an application can perform initialization tasks. Typical initialization tasks include setting data field values and populating table windows and list boxes with data from a database. Message Variables hWndForm Window handle of current top-level window. hWndItem Handle of the object being created.
