} 視訊監控分屏其實比較簡單，比方我要做最大16個畫面，那麼做一個視訊類繼承自UserControl，為了方便管理16個畫面，做了一個panel用於放置畫面。至於視訊怎麼播放，獲取m_videoform[0].Handle的控制代碼
IntPtr render_wnd = m_videoform[0].Handle;
public VideoForm[] m_videoform = new VideoForm[16];
在主函式先初始化。
for (int i = 0; i < 16; i++)
{
m_videoform[i] = new VideoForm();
this.Controls.Add(this.m_videoform[i]);
m_videoform[i].SetWndIndex(i);
}
public partial class VideoForm : UserControl { int m_nIndex; //index public int m_iPlayhandle; //play handle public void SetWndIndex(int nIndex) { m_nIndex = nIndex; } public VideoForm() { InitializeComponent(); } private void VideoForm_Click(object sender, EventArgs e) { GMApplicationMain clientdemo = (GMApplicationMain)this.Parent; clientdemo.SetActiveWnd(m_nIndex); clientdemo.g_displaySplitcomboBox.Focus(); } }
