Subclassing a dialog class

Can you subclass a dialog?  I am thinking something along the lines of just adding a constructor to my dialog class that allows the IDD to be passed in, so you can basically run the same dialog with additional functionality and a different GUI on it.

Or it could have the additional functionality inside the original dialog, and just do the construction with the different IDD.  No subclass, just allowing a different GUI.

Any reasons why not to do something like this?

There should be no problem with doing this.

The only thing you have to look out for is to make sure you use the proper constructor, and that your child class sets up that constructor correctly.

Example:
//header *.h file
class xxCDialog : public CDialog
{
public:
     xxCDialog(UINT nIDTemplate, CWnd* pParent = NULL):CDialog(nIDTemplate,pParent){};
};

//*.cpp file
xCDialog::xCDialog(UINT nIDTemplate, CWnd* pParent)
: xxCDialog(nIDTemplate, pParent)
{
}
