using mouse hook to get selected text

[Igor Vartanov]

And another question is: what message CRecordPlayerDlg::OnMyMouseMove handles? If this is WM_MOUSEMOVE, how can you interpret param as MOUSEHOOKSTRUCT* while it's:

lParam

The low-order word specifies the x-coordinate of the cursor. The coordinate is relative to the upper-left corner of the client area.


The high-order word specifies the y-coordinate of the cursor. The coordinate is relative to the upper-left corner of the client area.

And if UWM_MOUSEMOVE is handled by that, are you sure your pointer points to the same process address space?
