WzdBttn.cpp -- a CBitmapButton class which converts double left clicks to
WzdBttn.h			left clicks (to make the button more responsive)

WzdBtmap.cpp -- a bitmap class which creates and maintains its own palette
WzdBtmap.h

/////////////////////////////////////////////////////////////////////
// Putting a bitmap on a button face.
/////////////////////////////////////////////////////////////////////

// 1) use Dialog Editor to select the button and choose the Bitmap option

// 2) embed a CBitmap class in the dialog/view class you want to create the button

// 3) in the OnInitDialog() or OnCreate() handler of dialog/view class, load a 
// bitmap and tell button about it:

	m_bitmap.LoadBitmapEx(IDB_WZD_BUTTON,TRUE);
	((CButton *)GetDlgItem(IDC_WZD_BUTTON1))->SetBitmap(m_bitmap);

/////////////////////////////////////////////////////////////////////
// Defining the four bitmaps of a button.
/////////////////////////////////////////////////////////////////////

// 1) use the Bitmap Editor to create up to four bitmaps using a text id rather
// then a numeric id with the exact same name id but with four different appended
// characters as defined here:
//		NAMEU -- button's appearance when up
//		NAMED -- button's appearance when down
//		NAMEF -- button's appearance when it has focus
//		NAMEX -- button's appearance when disabled

// 2) use Dialog Editor to add a button control to a dialog template and give it
// the same name used above without an appended character (i.e. just NAME). Also 
// give this button the Owner Drawn style.

// 3) use the ClassWizard to subclass the button and change the default CButton
// class name to CBitmapButton


// 4) load the bitmaps into the button class in the initialization of the dialog box:
	m_bitmapButton.AutoLoad(
				IDC_WZD_BUTTON,  -- button id
				this);			 -- parent window
