我制作了很多使用c#和一个简单的webBrowser控件的机器人。 但是,通常我会尝试自动化元素上的“单击”功能,而不使用实际模拟游标并调用点击。
例子:
webBrowser1.Document.GetElementById("elementid").InvokeMember("Click");
我觉得这更容易比实际模拟光标,但是模拟光标也可以实现相对容易,这里的代码,我通常使用:
//Example of how to use it:
Point controlLoc = this.PointToScreen(webbrowser1.Location);
controlLoc.X = controlLoc.X + webbrowser1.Document.GetElementById("elementid").OffsetRectangle.Left;
controlLoc.Y = controlLoc.Y + webbrowser1.Document.GetElementById("elementid").OffsetRectangle.Top;
Cursor.Position = controlLoc;
MouseSimulator.ClickLeftMouseButton();
public class MouseSimulator
{
[DllImport("user32.dll", SetLastError = true)]
static extern uint SendInput(uint nInputs, ref INPUT pInputs, int cbSize);
[StructLayout(LayoutKind.Sequential)]
struct INPUT
{
public SendInputEventType type;
public MouseKeybdhardwareInputUnion mkhi;
}
[StructLayout(LayoutKind.Explicit)]
struct MouseKeybdhardwareInputUnion
{
[FieldOffset(0)]
public MouseInputData mi;
[FieldOffset(0)]
public KEYBDINPUT ki;
[FieldOffset(0)]
public HARDWAREINPUT hi;
}
[StructLayout(LayoutKind.Sequential)]
struct KEYBDINPUT
{
public ushort wVk;
public ushort wScan;
public uint dwFlags;
public uint time;
public IntPtr dwExtraInfo;
}
[StructLayout(LayoutKind.Sequential)]
struct HARDWAREINPUT
{
public int uMsg;
public short wParamL;
public short wParamH;
}
struct MouseInputData
{
public int dx;
public int dy;
public uint mouseData;
public MouseEventFlags dwFlags;
public uint time;
public IntPtr dwExtraInfo;
}
[Flags]
enum MouseEventFlags : uint
{
MOUSEEVENTF_MOVE = 0x0001,
MOUSEEVENTF_LEFTDOWN = 0x0002,
MOUSEEVENTF_LEFTUP = 0x0004,
MOUSEEVENTF_RIGHTDOWN = 0x0008,
MOUSEEVENTF_RIGHTUP = 0x0010,
MOUSEEVENTF_MIDDLEDOWN = 0x0020,
MOUSEEVENTF_MIDDLEUP = 0x0040,
MOUSEEVENTF_XDOWN = 0x0080,
MOUSEEVENTF_XUP = 0x0100,
MOUSEEVENTF_WHEEL = 0x0800,
MOUSEEVENTF_VIRTUALDESK = 0x4000,
MOUSEEVENTF_ABSOLUTE = 0x8000
}
enum SendInputEventType : int
{
InputMouse,
InputKeyboard,
InputHardware
}
public static void ClickLeftMouseButton()
{
INPUT mouseDownInput = new INPUT();
mouseDownInput.type = SendInputEventType.InputMouse;
mouseDownInput.mkhi.mi.dwFlags = MouseEventFlags.MOUSEEVENTF_LEFTDOWN;
SendInput(1, ref mouseDownInput, Marshal.SizeOf(new INPUT()));
INPUT mouseUpInput = new INPUT();
mouseUpInput.type = SendInputEventType.InputMouse;
mouseUpInput.mkhi.mi.dwFlags = MouseEventFlags.MOUSEEVENTF_LEFTUP;
SendInput(1, ref mouseUpInput, Marshal.SizeOf(new INPUT()));
}
这将左键单击加载的webBrowser控件中名为“elementid”的任何元素。请注意,可以很容易地实现其他MouseEventFlags:
下面是右键单击一个例子:
public static void ClickRightMouseButton()
{
INPUT mouseDownInput = new INPUT();
mouseDownInput.type = SendInputEventType.InputMouse;
mouseDownInput.mkhi.mi.dwFlags = MouseEventFlags.MOUSEEVENTF_RIGHTDOWN;
SendInput(1, ref mouseDownInput, Marshal.SizeOf(new INPUT()));
INPUT mouseUpInput = new INPUT();
mouseUpInput.type = SendInputEventType.InputMouse;
mouseUpInput.mkhi.mi.dwFlags = MouseEventFlags.MOUSEEVENTF_RIGHTUP;
SendInput(1, ref mouseUpInput, Marshal.SizeOf(new INPUT()));
}
这里有一个类似的帖子http://stackoverflow.com/questions/1964529/online-trading-bot其中有一个建立一个扑克机器人链接http://www.codingthewheel.com/archives/how-i-built-a-working-poker-bot。显然我想做类似的smtn,但我很好奇这些天有没有更好的工具。尽管查看发送和接收的数据更容易,但查看屏幕并使计算机移动鼠标更为普遍。 – 2010-11-20 19:07:50
看起来像这可能也是一种方式来做到这一点http://www.mjtnet.com/blog/2006/10/11/see-the-screen-with-image-recognition/ – 2010-11-20 20:09:53
