wine users - May 2011 - Hey! GWLP_USERDATA is for the user, not for the OS !

Hi

In the definition of IOCS_Attach in atl_ax.c, a "this" handle is
stored in the window user data with SetWindowLongPtr and the GWLP_USERDATA
parameter. This is used when an ActiveX control is attached to a window.

The user data is for the user, not for the OS, and a weird interaction happens
when a window that already uses the user data is supposed to be hosting an
ActiveX object.

Correct, and that's the way it supposed to work. Do you have any specific
problem?
