CAxDialogImpl Class

This class implements a dialog box (modal or modeless) that hosts ActiveX controls.

template <
   class T,
   class TBase = CWindow
class ATL_NO_VTABLE CAxDialogImpl :
   public CDialogImplBaseT< TBase >


Your class, derived from CAxDialogImpl.


The base window class for CDialogImplBaseT.

CAxDialogImpl allows you to create a modal or modeless dialog box. CAxDialogImpl provides the dialog box procedure, which uses the default message map to direct messages to the appropriate handlers.

CAxDialogImpl derives from CDialogImplBaseT, which in turn derives from TBase (by default, CWindow) and CMessageMap.

Your class must define an IDD member that specifies the dialog template resource ID. For example, adding an ATL Dialog object using the Add Class dialog box automatically adds the following line to your class:

enum { IDD = IDD_MYDLG };

where MyDialog is the Short name entered in the ATL Dialog Wizard.

See Implementing a Dialog Box for more information.

Note that an ActiveX control on a modal dialog box created with CAxDialogImpl will not support accelerator keys. To support accelerator keys on a dialog box created with CAxDialogImpl, create a modeless dialog box and, using your own message loop, use CAxDialogImpl::IsDialogMessage after getting a message from the queue to handle an accelerator key.

For more information on CAxDialogImpl, see ATL Control Containment FAQ.
