2.模拟鼠标
有时，我们需在我们的程序中模拟鼠标的移动、点击等动作。——比如，一个再现用户操作的宏，或者一个演示操作方法的Demo程序。那么，我们在.Net中如何实现呢？ .Net并没有提供改变鼠标指针位置、模拟点击操作的函数；但是Windows API提供了。其中一个是：
[DllImport( " user32.dll " )] static extern bool SetCursorPos( int X, int Y);
该函数可以改变鼠标指针的位置。其中X，Y是相对于屏幕左上角的绝对位置。 另一个函数是： [DllImport( " user32.dll " )] static extern void mouse_event(MouseEventFlag flags, int dx, int dy, uint data, UIntPtr extraInfo);
这个函数不仅可以设置鼠标指针绝对的位置，而且可以以相对坐标来设置。另外，该函数还可以模拟鼠标左右键点击、鼠标滚轮操作等。其中的MouseEventFlag是一个基于uint类型的枚举，定义如下： [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 }
关于这两个函数的详细说明，可以查看MSDN Library或者Windows的Platform SDK文档。 下面的演示程序（完整版源代码，VS.Net 2005/C#）演示了使用上面的函数，控制鼠标移动到任务栏并点击“开始”按钮的方法。 （该程序使用了FindWindowEx等API函数来查找任务栏及开始菜单） posted on 2007-08-07 22:01 阅读(185) 所属分类:

看一个参考MSDN上的 如何：在代码中模拟鼠标和键盘事件 Windows 窗体提供以编程方式模拟鼠标和键盘输入的几个选项。本主题提供这些选项的概述。 模拟鼠标输入 模拟鼠标事件的最佳方法是调用引发要模拟的鼠标事件的 OnEventName 方法。此选项通常只在自定义控件和窗体中是可能的，因为引发事件的方法受保护，而且不能从控件或窗体外部访问。例如，下面的步骤阐释如何用代码模拟单击鼠标右键的事件。 以编程方式单击鼠标右键 创建一个 Button 属性设置为 System.Windows.Forms.MouseButtons.Right 值的 MouseEventArgs。 将此 MouseEventArgs 用作参数调用 OnMouseClick 方法。 有关自定义控件的更多信息，请参见 设计时开发 Windows 窗体控件。 还有其他模拟鼠标输入的方法。例如，可以通过编程方式设置一个表示通常通过鼠标输入设置的状态的控件属性（如 CheckBox 控件的 Checked 属性），或者您可以直接调用附加到要模拟的事件的委托。 模拟键盘输入 虽然您可以通过使用上面讨论的鼠标输入策略来模拟键盘输入，但 Windows 窗体还提供了用于将键击发送到活动应用程序的 SendKeys 类。 警告 如果您的应用程序打算用于可以使用各种键盘的国际使用，则使用 System.Windows.Forms.SendKeys.Send(System.String) 可能产生不可预知的结果，因而应当避免。 注意 SendKeys 类已针对 .NET Framework 3.0 进行了更新，能够用于在 Windows Vista 上运行的应用程序中。Windows Vista 增强的安全性（称为用户账户控件或 UAC）使以前的实现无法按预期方式工作。 SendKeys 类容易出现计时问题，有些开发人员必须解决这个问题。更新的实现仍然容易发生计时问题，但速度略有提高，并且可能要求更改解决方法。SendKeys 类首先会尝试使用以前的实现，失败后再使用新的实现。因此，SendKeys 类的行为可能因操作系统的不同而有所差异。此外，当 SendKeys 类使用新的实现时，SendWait 方法在消息被发送到另一进程时不会等待消息的处理。 如果您的应用程序依赖于不受操作系统影响的一致性行为，则可通过向 app.config 文件添加以下应用程序设置，强制 SendKeys 类使用新的实现。 <appSettings> <add key="SendKeys" value="SendInput"/> </appSettings> 要强制 SendKeys 类使用以前的实现，请改用值 "JournalHook"。 向同一应用程序发送键击 调用 SendKeys 类的 Send 或 SendWait 方法。应用程序的活动控件将接收指定的键击。下面的代码示例使用 Send 在用户双击窗体的图面时模拟按 Enter 键。此示例假定一个 Form，该窗体具有单个 Tab 键索引为 0 的 Button 控件。 Visual Basic 复制代码 ' Send a key to the button when the user double-clicks anywhere ' on the form. Private Sub Form1_DoubleClick(ByVal sender As Object, _ ByVal e As EventArgs) Handles Me.DoubleClick ' Send the enter key to the button, which raises the click ' event for the button. This works because the tab stop of ' the button is 0. SendKeys.Send("{ENTER}") End Sub C# 复制代码 // Send a key to the button when the user double-clicks anywhere // on the form. private void Form1_DoubleClick(object sender, EventArgs e) { // Send the enter key to the button, which raises the click // event for the button. This works because the tab stop of // the button is 0. SendKeys.Send("{ENTER}"); } C++ 复制代码 // Send a key to the button when the user double-clicks anywhere // on the form. private: void Form1_DoubleClick(Object^ sender, EventArgs^ e) { // Send the enter key to the button, which triggers the click // event for the button. This works because the tab stop of // the button is 0. SendKeys::Send("{ENTER}"); } 向另一个应用程序发送键击 激活将接收键击的应用程序窗口，然后调用 Send 或 SendWait 方法。由于没有激活另一个应用程序的托管方法，因此必须使用本机 Windows 方法强制将焦点放在其他应用程序上。下面的代码示例使用平台调用来调用 FindWindow 和 SetForegroundWindow 方法，以激活计算器应用程序窗口，然后调用 SendWait 向计算器应用程序发出一系列计算。 Visual Basic 复制代码 ' Get a handle to an application window. Declare Auto Function FindWindow Lib "USER32.DLL" ( _ ByVal lpClassName As String, _ ByVal lpWindowName As String) As IntPtr ' Activate an application window.
