用c#在智能设备中播放声音 我按照MSDN中的方法做了次
可是不知道为什么就是不能播放出声音 希望高手帮忙解决下 谢谢!
coredll.dll 这个DLL 我在我的Pocket PC中没找到 ,我是在网上下载的!
以下是我从MSDN中复制下来的代码放在程序中用,可是没声音出来
internal class Helpers
{
[Flags]
public enum PlaySoundFlags : int
{
SND_SYNC = 0x0000, /* play synchronously (default) */
SND_ASYNC = 0x0001, /* play asynchronously */
SND_NODEFAULT = 0x0002, /* silence (!default) if sound not found */
SND_MEMORY = 0x0004, /* pszSound points to a memory file */
SND_LOOP = 0x0008, /* loop the sound until next sndPlaySound */
SND_NOSTOP = 0x0010, /* don't stop any currently playing sound */
SND_NOWAIT = 0x00002000, /* don't wait if the driver is busy */
SND_ALIAS = 0x00010000, /* name is a registry alias */
SND_ALIAS_ID = 0x00110000, /* alias is a predefined ID */
SND_FILENAME = 0x00020000, /* name is file name */
SND_RESOURCE = 0x00040004 /* name is resource name or atom */
}
[DllImport("coredll.dll", EntryPoint = "PlaySound", SetLastError = true)]
public static extern bool PlaySound(string szSound, IntPtr hMod, PlaySoundFlags flags);
}
public class Sound
{
public static void Play(string strFileName)
{
Helpers.PlaySound(strFileName, IntPtr.Zero, Helpers.PlaySoundFlags.SND_FILENAME | Helpers.PlaySoundFlags.SND_ASYNC);
}
}
private void button1_Click(object sender, EventArgs e)
{
Sound.Play("My Documents\\123.mp3");
}
