Hi,

I am currently having problems trying to code Tab control using Property Sheets and Property Pages. My first version of my work is a single dialog box, now due to the many components, I wish to put them in tabs instead.

I am able to get the tab dialog out without any problems thanks to the tutorials here. However it seems like the tabs (IDD_PROPPAGE_LARGE) does not have the OnInitDialog() method which is used to initialize a normal dialog box. I tried to add the code before I add the property page to the sheet but it gives an error that
the component is null.

C++

[code]
// 

// previously:
BOOL CDialogTest1::OnInitDialog()
{
	CDialog::OnInitDialog();

	// Set the icon for this dialog.  The framework does this automatically
	//  when the application's main window is not a dialog
	SetIcon(m_hIcon, TRUE);			// Set big icon
	SetIcon(m_hIcon, FALSE);		// Set small icon

	// TODO: Add extra initialization here
	CEdit *pEdit1 = (CEdit*) GetDlgItem(IDC_EDIT1); // unable to get CWnd here
        pBtn1->SetWindowText(CString("XXX"));

	//init flags
	mFlaga = false;
        mFlagb = false;
        mFlagc = false;
	mMsgLen   = 0;

// .........
[/code]

The second problem i am facing is that when a component e.g. a button in a tab dialog is pressed, it will update another tab dialog's mfc component e.g. list control. is that possible?

Download the property sheet sample from here[^].

You can use SendMessage() mechanism to communicate the event. And on the receive of this event, the other dialog/tab will perform the required control updated.

Generally, I use the following structure when I deal with PropertySheet

Works well.

Code example creates a property sheet styled dialog, in my case it is handled in CMainFrame class but you could equally handle it in View or Document

void CMainFrame::OnOptions()
{
	CPropertySheet psheet;
	CPropPage1 p1;		// CPropPage1 derived from CPropertyPage
	CPropPage2 p2;		// CPropPage2 derived from CPropertyPage
			
	//
	// Init is a custom method implemented in CPropPage1 and CPropPage2
	// For example, you may want to initialize data in property page objects
	//
	p1.Init();		
	p2.Init();
		
	// set the title
	psheet.SetTitle("My Options",0);

	//add all the pages into the PropertySheet
	psheet.AddPage(&p1);
	psheet.AddPage(&p2);
	
	//
	// The first call to this will cause An exception which is safely handled by OS
	// See Microsoft's explanation
	// http://support.microsoft.com/kb/q158552/
	//
	// Display the property sheet...
	if (psheet.DoModal() == IDOK)
	{
		//
		// PostProcessing is a custom method implemented in CPropPage1 and CPropPage2
		// For example, you may want to copy data from p1 and p2 to your document
		//
		p1.PostProcessing();
		p2.PostProcessing();
	}
}
