Fade Button control

Here is yet another control, which uses the DIB (Device Independent Bitmap) classes I wrote some time ago.

The control slowly fades between two bitmaps when the mouse hovers over it.
It uses the same DIB classes and image filters as I used in the Skinned UI sample (see link below).

How to use it

Place a button on a dialog. Then add a member variable to your dialog implementation file...

CFadeButtonCtrl m_ctrlButton;

In the OnInitDialog() event handler, add the following lines:

LRESULT OnInitDialog(UINT /*uMsg*/, 
                     WPARAM /*wParam*/, 
                     LPARAM /*lParam*/, 
                     BOOL& /*bHandled*/)
{
  ...
  m_ctrlButton.SubclassWindow(GetDlgItem(IDC_BUTTON1));
  m_ctrlButton.SetImages(IDB_NORMAL, IDB_GLOW);
  ...
}

Add the following reflection macro to your main message map:

BEGIN_MSG_MAP(CMainDlg)
  ...
  REFLECT_NOTIFICATIONS()
END_MSG_MAP()

Finally add two bitmaps with identifiers IDB_NORMAL and IDB_GLOW. It's a good idea to choose images with plenty of colours.
