3、	新建一.cpp文件，取名：TransparentWnd.cpp
代码内容如下：
// TransparentWnd.cpp : implementation file

#include "stdafx.h"
#include "West.h"

#ifdef _DEBUG
#define new DEBUG_NEW
#undef THIS_FILE
static char THIS_FILE[] = __FILE__;
#endif

/////////////////////////////////////////////////////////////////////////////
// TransparentWnd

TransparentWnd::TransparentWnd()
{
	m_iAniSeq=0; //图像变化初始值
}

TransparentWnd::~TransparentWnd()
{
}

BEGIN_MESSAGE_MAP(TransparentWnd, CWnd)
	//{{AFX_MSG_MAP(TransparentWnd)

	ON_COMMAND(IDR_HELP, OnHelp)
	ON_COMMAND(IDR_EXIT, OnExit)
	//}}AFX_MSG_MAP

		}
	}
	if (pOldMemBmp) memDC.SelectObject(pOldMemBmp);
	SetWindowRgn((HRGN)wndRgn, TRUE);
	MoveWindow(rcNewWnd);
}

void TransparentWnd::DoChange(void)
{
  char szBmp[20];

}

}

void TransparentWnd::OnLButtonDown(UINT nFlags, CPoint point) 
{

	//实现无标题拖动
	PostMessage(WM_NCLBUTTONDOWN, HTCAPTION, MAKELPARAM(point.x,point.y)); 	
}

void TransparentWnd::OnRButtonDown(UINT nFlags, CPoint point) 
{
	
	CWnd::OnRButtonDown(nFlags, point);

   DestroyWindow(); //鼠标右键点击时关闭此程序
}

4、	在应用类(West.cpp)代码中初始化实例涵数改为下面既可：
　　BOOL CWest::InitInstance()
{
		srand(time(NULL));
    
	//一次只运行一个程序实例，如果已运行则退出
	if( FindWindow(NULL,"大话西游经典系列之--情感天地")) exit(0);

	TransparentWnd* pFrame = new TransparentWnd;
	m_pMainWnd = pFrame;
    
	// create and load the frame with its resources
	CRect rect(0, 0, 100, 100);
	pFrame->CreateTransparent("大话西游经典系列之--情感天地", rect);//IDB_MASK, IDB_BACK);
	pFrame->CenterWindow();  //初始显示窗体位置
	pFrame->ShowWindow(SW_SHOW);
	
	return TRUE;
}
