Hello

I am having a few issues when hooking WM_NCHITTEST in VB6 then reading
the new values given to Left and Top of a Usercontrol.

My Windows hook returns HTCAPTION for WM_NCHITTEST when the user
clicks on the Usercontrol. This has the affect of moving the
Usercontrol like dragging a form border.

The hook works correctly and the Usercontrol visually moves on the
form, but the values in Left and Top for the Usercontrol on the parent
form never changes. Its as if VB6 is never being informed that the
Usercontrol has moved. The same is true for Usercontrol.Extender.Left/
Top.

Any suggestions?

Thanks

Paul
