run rain cli private ntp click length erro truct

在網上看到有人問C#中模擬鼠標點擊按鈕的帖子，在VB中用API實現的代碼網上不少，可用C#寫的基本就沒有了，在這裏簡單寫個事例。

1、首先建一個Demo項目。只有一個表單，標題是"Demo"。裏面放一個按鈕Button1，Text設置為"Click Me"。編譯成exe。做事例用，這個代碼就不用貼出來了吧 呵呵。

2、新建項目，添加表單，拖個按鈕。代碼如下：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;

using System.Text;
using System.Windows.Forms;
using System.Runtime.InteropServices;
using System.Diagnostics;

namespace ClickButton_SendMessage
{
public delegate bool CallBack(IntPtr hwnd, int lParam);

public partial class frmMain : Form
{

[DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = true)]

static extern IntPtr FindWindow(string strClass, string strWindow);

[DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = true)]
static extern IntPtr EnumChildWindows(IntPtr hWndParent, CallBack lpEnumFunc, int lParam);

[DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = true)]

static extern int GetWindowRect(IntPtr hwnd,RECT lpRect);

[DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = true)]
static extern int SetCursorPos(int x,int y);

[DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = true)]
static extern int SetForegroundWindow(IntPtr hwnd);

[DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = true)]
static extern void mouse_event(int dwFlags,int dx,int dy,int cButtons, int dwExtraInfo);
public const int MOUSEEVENTF_LEFTDOWN = 0x2;
public const int MOUSEEVENTF_LEFTUP = 0x4;

[DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = true)]
static extern int GetWindowText(IntPtr hwnd, string lpString, int cch);

[DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = true)]
static extern int GetWindowTextLength(IntPtr hwnd);

public struct RECT
{
public int Left;
public int Top;
public int Right;
public int Bottom;
}

public struct POINT
{
public int x;
public int y;
}

public static int nCount;

public frmMain()
{
InitializeComponent();

}

public static bool EnumWindowsProc(IntPtr h, int lParam)
{

string strText=new string((char)0,255);
RECT hRect=new RECT();

nCount = nCount + 1;

int Ret=0;

Ret = GetWindowTextLength(h);
string sSave = new string((char)9, Ret);
GetWindowText(h, sSave, Ret + 1);
if(sSave.IndexOf("Click Me",0) > -1)
{
//GetWindowRect(h, hRect);
//SetCursorPos((hRect.Left + hRect.Right) / 2, (hRect.Top + hRect.Bottom) / 2);
SetCursorPos(200, 160);//這是用Spy++直接獲取的，VS都帶這個工具
SetForegroundWindow(h);
mouse_event(MOUSEEVENTF_LEFTDOWN | MOUSEEVENTF_LEFTUP, 0, 0, 0, 0);
return false;
}
return true;
}

private void button1_Click(object sender, EventArgs e)
{
IntPtr h;
string strName = "Demo";
h = FindWindow(null, strName);
Debug.Print(h.ToString());
if (h.ToInt32() != 0)
{
CallBack myCallBack = new CallBack(frmMain.EnumWindowsProc);
EnumChildWindows(h, myCallBack, 0);
}
}
}
}
3、如果想不停的點擊 加個Timer不停點擊。 或者加個變量IsLogin = FindWindow(null,"登陸成功後的標題 或 登錄失敗提示標題")
另外，只有登錄按鈕所在的窗體在激活時才能點中。 可以用ShowWindow()先激活窗體，然後再進行點擊操作。
