Hi there,

I noticed that the WM_NCLBUTTONUP does not seem to behave as I expected, eg.
.. . . . .

LRESULT Subclass()
{
static BOOL check = false;

swicth(msg)
{

case WM_NCLBUTTONDOWN:
check = true;
break;

case WM_NCLBUTTONUP:
check = false;
break;
}

}



So when you release the mouse button(WM_NCLBUTTONUP)
the boolean does not change to false? Does anybody
know what the fix is for this, if there is indeed an issue.
Any suggestions would be appreciated?


Thanks!

Perhaps this page explains what happens to you:

What is your function supposed to return? If you do not indicate that you
handled the "down" message, there is no reason to tell you that it is "up".

It's was just to give a rough outline. The code posted will not work, but
just to show
a basic idea. Thanks.

Yes, that code "posted" will not work, as you have stated above. It was just
to give
a rough outline.
