Hi, > Is it clear?
Yes, clear and robust solution. Thank you very much. I try to use CreateWindow(Ex) parameter LPVOID lpParam. There can be address of memory or any value ( LPVOID ) 0x12345678 and messages WM_NCCREATE, WM_CREATE receives in lParam structure CREATESTRUCT address, where member lpCreateParams have value passed through lpParam in CreateWindow(Ex). Have you experience on this?
