    <p>I am using MyPrintDialog extended CPrintDialog. The problem is: OnInitDialog() method of MyPrintDialog does not get called on first time when the application try to open Print dialog.</p> <p>I am trying to set the Printer name in the Print Dialog from the OnInitDialog() method. Printer name is specified by the user in the application which I want to use for the Printing.</p> <p>My OnInitDialog() method</p> <pre><code>CComboBox *wndCmbBox = (CComboBox *)GetDlgItem( IDC_PER_USER ); /*IDC_PER_USER which is ID of Prin Dialog combo */ if( wndCmbBox != NULL ) { wndCmbBox-&gt;SelectString( -1, PrinterName ); } </code></pre> <p>Or is their any way to set the user choice Printer name in the Print dialog..?</p> <p>Please Explain.</p> <p><strong>Edit</strong></p> <p>Yes, by onInit() I mean <code>OnInitDialog()</code></p> <p>I am using VS 2012 with Win7 32 bit. I am facing this issue only first call of <code>DoModel()</code>. Next consecutive <code>DoModel()</code> methods calls <code>OnInitDialog()</code>. I have debug the issue and found something</p> <pre><code>INT_PTR CALLBACK AfxDlgProc(HWND hWnd, UINT message, WPARAM, LPARAM) { if (message == WM_INITDIALOG) { // special case for WM_INITDIALOG CDialog* pDlg = DYNAMIC_DOWNCAST(CDialog, CWnd::FromHandlePermanent(hWnd)); if (pDlg != NULL) return pDlg-&gt;OnInitDialog(); else return 1; } return 0; } </code></pre> <p>The above is the function of dlgcore.cpp. When issue is reproduced I observed that <code>DYNAMIC_DOWNCAST</code> returns <code>NULL</code>.</p> <p>Please note that I have customized CPrintDialog and added one check box in it. I doubt if it is creating the issue.</p>

    2. COAlso, if you use the supplied CPrintDialog instead of your customised version, does it also behave the same way? So, have you verified that your customisation is *not* to blame?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
