***********************************************************
And finally

Add four CommandButtons To the form, leaving them With their default names.
Change the Style Property of Each To Graphical, And assign a Picture To Command3.
The CommandButtons can also be placed In a container that Is a child of the form,
such As a PictureBox Or Frame,
because our module will automatically subclass a button's container if needed.
Now, Add the following code:

Private Sub Form_Load()

'Initialize Each button color.
SetButton Command1.hWnd, vbRed
SetButton Command2.hWnd, &H8000& 'Darker green
'Assign this one a DT_BOTTOM alignment because
'it has a picture.
SetButton Command3.hWnd, vbBlue, DT_BOTTOM
SetButton Command4.hWnd, &H8080& 'Darker brownish-yellow

End Sub

Private Sub Form_Unload(Cancel As Integer)

'Unhook CommandButtons manually -
'Note that this is Not really necessary,
'but you can Do this To remove the
'text coloring effect at any time.
RemoveButton Command1.hWnd
RemoveButton Command2.hWnd
RemoveButton Command3.hWnd
RemoveButton Command4.hWnd

End Sub;
