定义：
Process process = null;
IntPtr appWin;
private string exeName = "";
[DllImport("user32.dll", EntryPoint = "GetWindowThreadProcessId", SetLastError = true, CharSet = CharSet.Unicode, ExactSpelling = true,
CallingConvention = CallingConvention.StdCall)]
private static extern long GetWindowThreadProcessId(long hWnd, long lpdwProcessId);

[DllImport("user32.dll", SetLastError = true)]
private static extern long SetWindowPos(IntPtr hwnd, long hWndInsertAfter, long x, long y, long cx, long cy, long wFlags);

public string ExeName
{

{

}
set
{

}
}
调用：
this.exeName = @"C:\Program Files\Kingview\Touchvew.exe";
try
{
// Start the process
process = System.Diagnostics.Process.Start(this.exeName);
// Wait for process to be created and enter idle condition
process.WaitForInputIdle();
// Get the main handle
appWin = process.MainWindowHandle;
}
catch (Exception ex)
{
MessageBox.Show(this, ex.Message, "Error");
}
// Put it into this form
SetParent(appWin, this.splitContainer1.Panel2.Handle);
// Remove border and whatnot
// SetWindowLong(appWin, GWL_STYLE, WS_VISIBLE);
// Move the window to overlay it on this window
MoveWindow(appWin, 0, 0, this.Width, this.Height, true);
在控件改变大小的时候，调用：
private void splitContainer1_Panel2_Resize(object sender, EventArgs e) {
if (this.appWin != IntPtr.Zero)
{
MoveWindow(appWin, 0, 0, this.splitContainer1.Panel2.Width, this.splitContainer1.Panel2.Height, true);
}
base.OnResize(e);
}
窗口退出时：
private void Form1_FormClosed(object sender, FormClosedEventArgs e)
{
process.Kill();
// Stop the application
//if (appWin != IntPtr.Zero)
//{
// // Post a colse message
