I would like to ask how can I display a modeless dialog box.
Actually I created the modeless dialog using CDialog::Create.. After creating , the dialog box is not displayed.. Then I try to use ShowWindow() after the creation but the dialog box is still not displayed

If you have Visual C++ 5.0 check on the CD in the /Samples/General/Modeless directory for a sample of a modeless dialog.

I believe you do a DialogName.DoModal();  even though the dialog should be modeless.

Check the samples!

Try DoModal(), too.

  Code like this has always worked for my non-modal dialog boxes:

/**/    CMyDialog::CMyDialog( CWnd *pParent ) :
            CDialog( IDD, pParent )
{
    Create( IDD, pParent );
    ShowWindow( SW_SHOW );

    return;
}

   If you have something like that, and it is not working, make sure that your dialog template (and all of its controls ) is/are loading correctly.

Here is what you need to do. Shown below is the code in the
dialog constructor

CModeLessDlg::CModeLessDlg(CWnd* pParent /*=NULL*/)
      : CDialog(CModeLessDlg::IDD, pParent)
{
      //{{AFX_DATA_INIT(CModeLessDlg)
            // NOTE: the ClassWizard will add member initialization here
      //}}AFX_DATA_INIT
      Create(CModeLessDlg::IDD,pParent);
}

Below is the code to create the dialog box (in view for example)

void CWebClientView::OnModelessDialog()
{
      // TODO: Add your command handler code here
      if(pDlg==NULL)   //pDlg is a Dialog pointer in view.h
      {
       pDlg=new CModeLessDlg(this);
       pDlg->ShowWindow(SW_SHOW);
      }

      
}

You can avoid calling ShowWindow if you set the the properties
of the dialog template properly. In particular, set the visible
property to true under "more styles"
