I have solved my problem : SetWindowLong(WndInfo->WindowHandle, GWL_USERDATA, (long)this); After creating the window in my class, I simple pass the address of the instance to the window, then when the static WNDPROC is called I simply do : MyWindow *curWnd = (MyWindow *)GetWindowLong(hWnd, GWL_USERDATA); I can now refer to curWnd knowing its the correct instance! I have create 5 windows as the same time and they all process their own messages correctly!
