QuestionUsing a Dialog as a Control in another Dialog Pin

I do this a lot in one of my older applications. Suppose your two dialogs are IDD_MAIN and IDD_SUB, with corresponding MFC classes CMainDlg and CSubDlg. The resource for the sub dialog should have the following styles set: Border=None, Style=Child, and Control=True. This will let the sub dialog visually blend into the main dialog.

The basic approach is to use the sub as a modeless dialog whose parent is the main dialog. You then need something like this to get it going:
BOOL CMainDlg::OnInitDialog()
{
    // create sub-dialog
    CSubDlg *sub = new CSubDlg(CSubDlg::IDD,this);
    sub->Create(CSubDlg::IDD,this);
    sub->MoveWindow(10,10,100,100);
    sub->ShowWindow(SW_SHOW);
}
Obviously, there are lots of ways this needs to be fancied up. You probably want this sub-dialog positioned relative to other controls. What I usually do is place a static control where I want the sub-dialog to go, and then position the sub-dialog using logic like this:
// create sub-dialog
CSubDlg *sub = new CSubDlg(CSubDlg::IDD,this);
sub->Create(CSubDlg::IDD,this);
CRect sub_rect;
GetDlgItem(IDC_SUB_DIALOG)->GetWindowRect(&sub_rect);
ScreenToClient(&sub_rect);
GetDlgItem(IDC_SUB_DIALOG)->DestroyWindow();
sub->SetDlgCtrlID(IDC_SUB_DIALOG);
sub->MoveWindow(&sub_rect);
This logic does several things: it gets the position of the static control, destroys it, and then places the sub dialog in the same position. As a final refinement, it assigns the control ID to the sub dialog.

Note that, for completeness, you really should save the pointer to the sub dialog instance as a member of the main dialog class, and delete it in that class' PostNcDestroy().
Software Zen: delete this;
