VC#2003中 API做的音乐播放,怎么停止?
代码如下:
[DllImport("winmm.dll")]  
public static extern int mciSendString(string m_strCmd, string m_strReceive, int m_v1, int m_v2);  
[DllImport("Kernel32", CharSet = CharSet.Auto)]  
static extern Int32 GetShortPathName(String path,StringBuilder shortPath, Int32 shortPathLength);  
private static void playMusic(string name)  
{  
	StringBuilder shortpath = new StringBuilder(80);  
	int result = GetShortPathName(name, shortpath, shortpath.Capacity);  
	name = shortpath.ToString();  
	string buf = string.Empty;  
	mciSendString("play "+name,buf, buf.Length, 0);
}	
private void Form1_Load(object sender, System.EventArgs e)
{			
}
private void radio_music1_CheckedChanged(object sender, System.EventArgs e)
{						
	playMusic("忧伤还是快乐.mp3");
}
private void radio_music2_CheckedChanged(object sender, System.EventArgs e)
{			
	playMusic("飘雪.mp3");
}
页面有两个radiobutton, 选第一个时第一个歌曲播放,选第二个时第一个歌曲停止,第二个播放。播放该怎样停止???
------解决方案--------------------    一,播放
   mciSendString("play movie",buf,sizeof(buf),NULL);  
  二,如果想全屏播放:  
  mciSendString("play movie fullscreen",buf,sizeof(buf),NULL);  
  三,暂停播放。  
  mciSendString("pause movie",buf,sizeof(buf),NULL);  
  四,停止播放。  
  mciSendString("close movie",buf,sizeof(buf),NULL);  
  五,得到所播放文件的长度。  
  char sPosition[256];long lLength;  
  ciSendString("Status movie length", sPosition, 255,0);lLength=strtol(sPosition, NULL, 10);  
  其中lLength就是所播放文件的长度。  
------解决方案--------------------建议你下个media的dll,这个比调用上面哪些api函数要好用的多!
