Modal dialog problem

[Johnny Peszek]

Hi! I have dialog based application with one modal dialog. The modal dialog should take some data from dialog based application and display it on the screen in the Edit Box. How to do it? Thanks!

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.

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. Regards.

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? Regards.

I messed up. :doh: Johnny Peszek wrote: What should I do? Recheck my post again. Sorry about that.
