It sounds like there are two programs involved here. Is that correct? If so, you'll need to use some form of IPC such as DDE, clipboard, RPC, or the WM_COPYDATA message.

Use CWnd::SetWindowText(), or send the edit control a WM_SETTEXT message.

no, I think he want to have the parent's dialog application data display in a modal dialog of that dialog application

anyway, You can either passer the data in the modal dialog constructor ( override the current constructor ) or pass the parent pointer to the modal dialog.

As a matter of fact there is only one program (dialog based) and it processes data. And there is also a modal dialog as an inserted dialog resource.

That's simple enough then. Change the constructor of the second dialog to also accept a pointer to the first dialog (the parent). Then the second dialog will have access to properties/methods of the first dialog. Something like:

class CDialog2 : public CDialog
{
public:
    CDialog2( CDialog1 *pDlg, CWnd *pParent = NULL);
private:
    CDialog1 *m_pDlg;
}
 
CDialog2::CDialog2( CDialog1 *pDlg, CWnd *pParent )
    : CDialog(CDialog2::IDD, pParent)
{
    m_pDlg = pDlg;
}
...
// in a CDialog1 method
CDialog2 dlg(this);
dlg.DoModal();

It looks fine. I have done everything as you wrote but there is 1 error:
“error C2512: 'CDialog2' : no appropriate default constructor available”.
The error occurs in the method of the CDialog1 in line with CDialog2 dlg;
What should I do?

You should not have a problem on WinXP. I have written code that uses those parameters to GetSystemMetrics() and they return the appropriate x and y for the virtual screen when running on XP.

Can you elaborate on what you mean by not working?

Additionally to what has already been stated.

If you have multiple monitors (or want multiple monitor support) us

SM_CXVIRTUALSCREEN to get the x
SM_CYVIRTUALSCREEN to get the y

As the parameter to GetSystemMetrics

NOTE: the rect will be (0, 0, x, y)
