在网上看到有人问C#中模拟鼠标点击按钮的帖子,在VB中用API实现的代码网上不少,可用C#写的基本就没有了,在这里简单写个事例。
1、首先建一个Demo项目。只有一个表单,标题是"Demo"。里面放一个按钮Button1,Text设置为"Click Me"。编译成exe。做事例用,这个代码就不用贴出来了吧 呵呵。
2、新建项目,添加表单,拖个按钮。代码如下:
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);//这是用Spy++直接获取的,VS都带这个工具 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、如果想不停的点击 加个Timer不停点击。 或者加个变量IsLogin = FindWindow(null,"登陆成功后的标题 或 登录失败提示标题") 另外,只有登录按钮所在的窗体在激活时才能点中。 可以用ShowWindow()先激活窗体,然后再进行点击操作。
