   It sounds like a good suggestion, but now it seems I am not sure "how to"
determine if the mouse is in draggable area. Even only a small area similar
to a standard titlebar.
   I tried the code below, and it's not correctly working. I used a "simple"
static control set to notify, and this is probably not the right approach.
Because I can only drag the dialog after I clicked the hidden control area,
then reclick anywhere in the dialog to drag. And I needed only this border
to be the draggable area. Also, I cannot drag from the control area at all
after it has been clicked.
   I would prefer using OnNcHitTest( ), but I am not sure how to determine
the draggable area.

if(bMove)
PostMessage(WM_NCLBUTTONDOWN, HTCAPTION, MAKELPARAM(point.x,point.y));

bMove = false;

CDialog::OnLButtonDown(nFlags, point);
}

I tried your code suggestion with a few modifications for a program

that

has a border (about the width of a standard titlebar) around the entire
dialog. And this border would be the only draggable area.

However, it is not dragging the dialog. Do you know of any other code

approach for doing this, or do see any problems with the code below.
