SubClass to catch WM_LBUTTONUP on titlebar   

Try to catch the WM_LBUTTONUP message when user click on titlebar.

Subclass the window (Style: 0x16CF0000, Ext Style: 0x40300), was able to 
catch WM_NCLBUTTONDOWN, but not WM_LBUTTONUP.  Any idea?

The window indeed get WM_LBUTTON msg, shown on Spy++.

Perhaps you should be trying to catch WM_NCLBUTTONUP instead.

Is this window in you own application? If so, you probably don't need to 
subclass it.

Norman,

Thanks for reply.

The window doesn't get WM_NCLBUTTONUP message.  I tried.  Not shown on Spy++ 
either.

The window isn't created by me.   I have to subclass.
