IntPtr appWin;
       
private string exeName =
""; 
       
[DllImport("user32.dll", EntryPoint =

private const

private const
int WS_VISIBLE = 0x10000000;
       
private const

private const

public string ExeName
       
{
           
get
           
{
               
return exeName;
           
}
           
set
           
{
    
           exeName = value;
           
}
       
} 
 
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
           
//    //PostMessage(appWin, WM_CLOSE, 0, 0); 
           
//    // Delay for it to get the message
           
//   // System.Threading.Thread.Sleep(1000); 
           
//    // Clear internal handle
           
//    appWin = IntPtr.Zero; 
           
//} 
           
//base.FormClosed(e); 
       
}
