Get a pointer to other dialog window

[portnov]

Hello,
I have dialog based app. main window opens another 2 dialogs (A and B), i am looking for a way passing data and updating it from event on dialog A to B.


//pointer to B dialog
InfoDlg *IWnd = (InfoDlg*)GetParent(); //<-- i dont remember how to set pointer to other window not to parent


// send data to B
IWnd->m_number = 1234;
// update data in B
IWnd->UpdateData(FALSE);

Thanks for help...
