Associating a dialog box to a view

I have a dialog box which has some controls. I want to invoke it from a menu item in a view. Also, I want to handle the ONCOMMAND handlers of the dialog box controls in the view. When I added code for the dialog, I selected 'Select and existing class' and I selected the view class, instead of 'Add a new class'.
The problem is, in the below code, since I did not specify a separate class 'Dialog' when I built the dialog, I cannot even call the Domodal function.
void View::OnShowDialog()
{
      Dialog dlg;
      dlg.DoModal();
}
How to achieve what I want to?
Thanks.

If you want to handle command messages by view and not dialog you must do the following:
1.Pass pointer to the view to dialog constructor, and store this pointer in dialog member variable.
2.Overide OnCmdMessage for your dialog class and in this function call m_pView->OnCmdMessage, whether m_pView is pointer to view class.
