axWindowsMediaPlayer1控件的全屏问题,
我这样写,就没有报错
private void button1_Click(object sender, EventArgs e)
{
this.axWindowsMediaPlayer1.fullScreen = true;
}
我这样写就报错了
private void listBox1_KeyDown(object sender, KeyEventArgs e)
{
switch (e.KeyCode)
{
case Keys.A:
this.axWindowsMediaPlayer1.fullScreen = true;
break;

}
}
为什么呀,求高手指点指点

未处理的“System.Runtime.InteropServices.COMException”类型的异常出现在 AxInterop.WMPLib.dll 中。

其他信息: 灾难性故障 (异常来自 HRESULT:0x8000FFFF (E_UNEXPECTED))

TRY过了,就是
private void listBox1_KeyDown(object sender, KeyEventArgs e)
{
switch (e.KeyCode)
{
case Keys.A:
this.axWindowsMediaPlayer1.fullScreen = true;
break;

}
}
里的
this.axWindowsMediaPlayer1.fullScreen = true;
这报错呀
