Hello,

I'm trying to subclass the ComboBox control so that I can process WM_MOUSEMOVE message. It seems that the WM_MOUSEMOVE messages are only sent to the child TextBox inside the combo, so I need to do FindWindowEx() first to get the handle.

I am getting a strange bug. If I subclass the combo box, it works fine. If I subclass the child text box, VB seems to get in an infinite loop and crash very fast (invalid page fault).

If anyone has any solution or any alternatives to getting mouse movement info for this control let me know.

Best regards,
Gabriel
