When a dialog box is nested, why is the sub-dialog box not displayed?

stacey

Style is Child in Style
  Border is None
  Select Control in More Styles
  Control parent selected in Extended Styles

  Then add the child dialog class member CInsideDlg in the parent dialog, and add it in OnInitDialog
CInsideDlg m_child;
m_child.Create (IDD_DIALOG1, this);
//m_child.ShowWindow(0);
m_child.MoveWindow (10,20,20,10, TRUE);
    //m_child.ModifyStyle(0, WS_TABSTOP, 0);
m_child.ShowWindow (SW_SHOW);

There is no problem in compiling, but the main dialog box after execution does not display sub dialog boxes. What is the reason?

too small?

m_child.MoveWindow (10,20,20,10, TRUE);

You and this are not a correct rectangle

bottom must be greater than top

Thanks in advance.
Is it the reason above?
Why do I add a button to the sub-dialog box and "CANNOT ADD NEW MEMBER" appears when I double-click?

Because the compiler cannot find a class that is combined with the dialog resource, you just add the message map by hand

Declare:
afx_msg void OnMyButtonClick ();

Map:
ON_COMMAND (Button ID, OnMyButtonClick)

void CMyDlg :: OnMyButtonClick ()
{
}

CInsideDlg m_child;
Put it in the .h file and see

CInsideDlg m_child; put it in the .h file
===============================================
