VC++编程技术连载－－－VC++制作具有声音效果的动画桌面精灵
具体实现步骤如下：
1、 在新建的工程文件中(VC6.0)中导入一WAV文件，取名"WEST"，再导入两幅位图取名"WEST1"和"WEST2" 。
2、 新建一.件，取名TransparentWnd.h
旧中国第一次正式参加奥运会是什么时候代码内容如下：
#if !defined(AFX_TRANSPARENTWND_H__6508F000_5685_11D3_9001_CBBD225E6BC4__INCLUDED_)
#define AFX_TRANSPARENTWND_H__6508F000_5685_11D3_9001_CBBD225E6BC4__INCLUDED_
#if _MSC_VER > 1000
#pragma once
#endif // _MSC_VER > 1000
// TransparentWnd.h : header file

3、新建一.cpp文件，取名：TransparentWnd.cpp

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;
}
