Simple Message question...

[craig.kelly]

I'm experimenting with the message object in C#. If I try to move the
window by clicking on the client area, why does this work:

private void baseForm_MouseD own(object sender, MouseEventArgs e)
{
Capture = false;
Message message = Message.Create( Handle, 161, (IntPtr)2, IntPtr.Zero);
WndProc(ref message);
}

but if I do the same thing from an object on the form:

private void label1_MouseDow n(object sender, MouseEventArgs e)
{
Capture = false;
Message message = Message.Create( Handle, 161, (IntPtr)2, IntPtr.Zero);
WndProc(ref message);
}

it doesn't work?

Hi Craig,

I think it would be easier to override WndProc, handle WM_NCHITTEST and once
the pointer is over the label, return HTCAPTION in response to WM_NCHITTEST.
