How to move a form by non-client area

See a description of how to move a form in a non-customer area, both overloading wm_nchittest and returning htcaption. But I think there's something wrong with the right mouse button function. Here I introduce a method, you can already move the form in the client area and the right mouse button function.

1, a new project dlg. Use the default settings.

2. Add Message handler function:

void CDlgDlg::OnLButtonDown(UINT nFlags, CPoint point)
{
　　PostMessage(WM_NCLBUTTONDOWN,HTCAPTION,MAKELPARAM(point.x,pointy));
　　CDialog::OnLButtonDown(nFlags, point);
}

3, add right key function. The right mouse button function has been implemented

void CDlgDlg::OnRButtonDown(UINT nFlags, CPoint point)
{
　 CMenu menu,*sub;
　 menu.LoadMenu(IDR_MENU1);
　 sub=menu.GetSubMenu(0);
　 ClientToScreen(&point);
　 sub->TrackPopupMenu(TPM_RIGHTBUTTON,point.x,point.y,this);
　 CDialog::OnRButtonDown(nFlags, point);
}

See source code for other implementation details.
