its a dialog based application.
every time the mouse is on the list control area the OnMouseMove of the dialog is not catching the event....

Use SetCapture/ReleaseCapture functions

You can also subclass the listctrl and in the CListCtrl derived class will you get the WM_MOUSEMOVE message.

Hi!
more general way:
install local MOUSE hook in the dialog and translate all message to the dialog procedure.

i defined message and used DefWindowProc in the dialog to catch it.
in the listCtrl i used GetParent()->SednMEssage(WM_THE_MSG,0x0,0x0) to notify the dialog on Mouse move, is it ok?

Highfive + Dolby Voice = No More Audio Complaints!

Poor audio quality is one of the top reasons people don’t use video conferencing. Get the crispest, clearest audio powered by Dolby Voice in every meeting. Highfive and Dolby Voice deliver the best video conferencing and audio experience for every meeting and every room.

You use subclassing via MFC classes so I don`t understand your last question.

IT, Stop Being Called Into Every Meeting

Highfive is so simple that setting up every meeting room takes just minutes and every employee will be able to start or join a call from any room with ease. Never be called into a meeting just to get it started again. This is how video conferencing should work!
