C#中获取窗口句柄的方法

C#可调用API接口来获取窗口句柄,代码如下
using  System;
using  System.Runtime.InteropServices;
namespace  tstfindwindow
{
///  <summary>
///  Class1  的摘要说明。
///  </summary>
class  Class1
{
    [DllImport( "User32.dll ")]
    public  static  extern  System.IntPtr  FindWindowEx(  System.IntPtr  parent  ,  System.IntPtr  childe  ,      string  strclass  ,string  strname  );
    ///  <summary>
    ///  应用程序的主入口点。
    ///  </summary>
    [STAThread]
    static  void  Main(string[]  args)
    {
    //
    //  TODO:  在此处添加代码以启动应用程序
    //
    IntPtr p=FindWindowEx(System.IntPtr.Zero,System.IntPtr.Zero,null,"窗口标题"); 
    }
}

c#编写QQ群发器

1、窗体引用两个timer控件，来控循环发送时间

2、调试环境 vs2005.net

程序代码

using System.Collections.Generic;
using System.ComponentModel;

using System.Drawing;
