CDialogBar does not support controls

[krugger]

HI all; I am building an application which should have a tab control on a CDialogBar. Visual C++ gladly added the dockable dialog bar for me but i could not figure out where to put the code to create the tab control since the OnInitDialog() function is simply ineffective. Can anybody please help out. I need to know where i should place my code to create the TAb control on the dialogbar. I badly need this guys; THanks Krugger

Let's assume you're trying to create the object using DDX. In other words, you've embedded an object of the correct type in your class definition and written a DoDataExchange function with the appropriate DDX_Control() call. It might look like this (simplified). Header file.

class CMyDialogBar : public CDialogBar
{
public:
CMyTabbedControl m_tabControl;

virtual void DoDataExchange(CDataExchange\* pDX);
virtual void OnInitDialog();

};

and your implementation file looks like this.

void CMyDialogBar::DoDataExchange(CDataExchange* pDX)
{
CDialogBar::DoDataExchange(pDX);
DDX_Control(pDX, IDC_MYTABCONTROL, m_tabControl);
}

void CMyDialogBar::OnInitDialog()
{
CDialogBar::OnInitDialog();

return TRUE;

}

And yet it doesn't work. As you've noticed, OnInitDialog() isn't called for a DialogBar. The solution I found was to add a function Initialise() to the DialogBar derived class and call it once I knew the dialog bar had been created.

void CMyDialogBar::Initialise()
{
UpdateData(FALSE);
}

Yes, it's that simple. Just call UpdateData() (make sure the call occurs before any code that tries to use the TabControl) and the control will be created.
