Actually, all it does (casting to LPSTR) is add the currect data segment to the offset (near). For instance, if you make a call like: CreateWindow(....., (LPSTR)this); It just pushes the data segment in addition to the 'this' pointer, thus on the stack goes a FAR pointer. |----------------------------------------------------------------------------| |Tom Hite | The views expressed by me | |Manager, Product development | are mine, not necessarily | |CADSI (Computer Aided Design Software Inc. | the views of CADSI. | |----------------------------------------------------------------------------|
