Wouldn't removing the flags that display the original buttons be an easier
solution?

Not sure I follow you. Are you saying process the flags so I know what
buttons to paint but then remove them from the style? That makes sense I
guess. Where's the best place to do that, PreCreateWindow?

Anyway, If you want to move the window yourself then here is the code
(roughly)

Hey, now I'm feeling pretty smart as this is basically what I tried but it
didn't work quite right. I'll doublecheck my code as I just did a quick
pass at it before posting this message.

Thanks

void CMyDialog::OnNcLButtonDown(UINT nHitTest,CPoint Pint)
{
   CDialog::OnNcLButtonDown(...);
   SetCapture();
   m_StartPoint = Point;
   m_Captured = TRUE;
}

void CMyDialog::OnNcMouseMove(UINT nHitTest,CPoint Point)
{
   CDialog::OnNcMouseMove(...);
   if (m_Captured)
   {
       CSize Diff = Point - m_StartPoint;
       CRect Rect;
       GetWindowRect(&Rect);
       GetParent()->ScreenToClient(&Rect);
       SetWindowPos(NULL,Rect.left -
Diff.cx,Rect.top-Diff.cy,0,0,SWP_NOSIZE|SWP_NOZORDER);
   }
}

void CMyDialog::OnNcLButtonUp(UINT nHitTest,CPoint Point)
{
   CDialog::OnNcLButtonUp(...);
   ReleaseCapture();
   m_Captured = FALSE;
}

In my custom CDialog I'm painting the non-client area and have to handle

the

OnNcLButtonDown message to determine what buttons are being pressed. I
don't make the call to the base class because it paints the default

buttons

in that underlying code. I am sending the WM_CLOSE message from the
OnNcLButtonUp if the mouse is over the Close button. That's working.
Now I need to handle the ability to click and drag the dialog from the
caption bar.

I'm assuming I'll need to handle this somehow in the OnNcMouseMove but am
missing the proper way.

AliR I tried looking at the SkinTest sample from codeproject but it's

pretty

involved in how he's implementing things and I'm a bit confused.

Thanks
