我想编制一个qq自动登陆程序,确发现C#中对很多api没有封装,只有使用平台调用了。其中用到窗体查找和虚拟键盘、虚拟鼠标等函数。具体代码如下:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Runtime.InteropServices;
namespace SimulateMouse
{
public partial class DemoForm : Form
{
[StructLayout(LayoutKind.Sequential)]
struct NativeRECT
{
public int left;
public int top;
public int right;
public int bottom;
}
[Flags]
enum MouseEventFlag : uint
{
Move = 0x0001,
LeftDown = 0x0002,
LeftUp = 0x0004,
RightDown = 0x0008,
RightUp = 0x0010,
MiddleDown = 0x0020,
MiddleUp = 0x0040,
XDown = 0x0080,
XUp = 0x0100,
Wheel = 0x0800,
VirtualDesk = 0x4000,
Absolute = 0x8000
}
[DllImport("user32.dll")]
static extern bool SetCursorPos(int X, int Y);
[DllImport("user32.dll")]
static extern void mouse_event(MouseEventFlag flags, int dx, int dy, uint data, UIntPtr extraInfo);
[DllImport("user32.dll")]
static extern IntPtr FindWindow(string strClass, string strWindow);
[DllImport("user32.dll")]
static extern IntPtr FindWindowEx(HandleRef hwndParent, HandleRef hwndChildAfter, string strClass, string strWindow);
[DllImport("user32.dll")]
static extern bool GetWindowRect(HandleRef hwnd, out NativeRECT rect);
[DllImport("user32.dll")]
static extern void keybd_event(byte bVk,byte bScan,uint dwFlags,uint dwExtraInfo);
private Point endPosition;
public DemoForm()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
NativeRECT rect;
IntPtr ptrTaskbar = FindWindow("#32770","QQ用户登录");
if (ptrTaskbar == IntPtr.Zero)
{
MessageBox.Show("No taskbar found.");
return;
}
IntPtr ptrStartBtn = FindWindowEx(new HandleRef(this, ptrTaskbar), new HandleRef(this, IntPtr.Zero), "ComboBox", null);
if (ptrStartBtn == IntPtr.Zero)
{
MessageBox.Show("No qq号码框 found.");
return;
}
GetWindowRect(new HandleRef(this, ptrStartBtn), out rect);
endPosition.X = (rect.left + rect.right) / 2;
endPosition.Y = (rect.top + rect.bottom) / 2;
SetCursorPos(endPosition.X, endPosition.Y);
mouse_event(MouseEventFlag.LeftDown, 0, 0, 0, UIntPtr.Zero);
mouse_event(MouseEventFlag.LeftUp, 0, 0, 0, UIntPtr.Zero);
mouse_event(MouseEventFlag.LeftDown, 0, 0, 0, UIntPtr.Zero);
mouse_event(MouseEventFlag.LeftUp, 0, 0, 0, UIntPtr.Zero);
System.IO.StreamWriter tw = new System.IO.StreamWriter(@"d:/aa.txt");
tw.Write("49593533");
tw.Close();
System.IO.StreamReader tr = new System.IO.StreamReader(@"d:/aa.txt");
String mystr = tr.ReadToEnd();
tr.Close();
for(int i=0;i<mystr.Length;i++)
keybd_event((byte)mystr[i], 0, 0, 0);
IntPtr ptrPassWord = FindWindowEx(new HandleRef(this, ptrTaskbar), new HandleRef(this, IntPtr.Zero), "#32770", null);
GetWindowRect(new HandleRef(this, ptrPassWord), out rect);
endPosition.X = (rect.left + rect.right) / 2;
endPosition.Y = (rect.top + rect.bottom) / 2;
SetCursorPos(endPosition.X, endPosition.Y);
mouse_event(MouseEventFlag.LeftDown, 0, 0, 0, UIntPtr.Zero);
mouse_event(MouseEventFlag.LeftUp, 0, 0, 0, UIntPtr.Zero);
mouse_event(MouseEventFlag.LeftDown, 0, 0, 0, UIntPtr.Zero);
mouse_event(MouseEventFlag.LeftUp, 0, 0, 0, UIntPtr.Zero);
mystr = "mypassword";
for (int i = 0; i < mystr.Length; i++)
{
keybd_event((byte)mystr[i], 0, 0, 0);
}
}
}
}
说明:(1)所有虚拟键盘码可以到http://msdn.microsoft.com/library/default.asp?url=/library/en-us/winui/WinUI/WindowsUserInterface/UserInput/VirtualKeyCodes.asp去查找。
(2)首先介绍一下Keybd_event函数。Keybd_event能触发一个按键事件,也就是说回产生一个WM_KEYDOWN或WM_KEYUP消息。当然也可以用产生这两个消息来模拟按键,但是没有直接用这个函数方便。Keybd_event共有四个参数,第一个为按键的虚拟键值,如回车键为vk_return, tab键为vk_tab。第二个参数为扫描码,一般不用设置,用0代替就行第三个参数为选项标志,如果为keydown则置0即可,如果为keyup则设成“KEYEVENTF_KEYUP”或者2,第四个参数一般也是置0即可。
keybd_event(VK_CONTROL, (BYTE)0, 0 ,0);
keybd_event('A',(BYTE)0, 0 ,0); //此处可以用 'A', (BYTE)65, 用'a'不起作用.
keybd_event('A', (BYTE)0, KEYEVENTF_KEYUP,0);
keybd_event(VK_CONTROL, (BYTE)0, KEYEVENTF_KEYUP,0);
