查找屏幕键盘的类名？ [英] Finding the class name of the On-Screen Keyboard?

问题描述

我试图用这个的代码示例从C＃（.NET 3.5）WinForms应用程序控制Windows XP屏幕键盘（OSK.exe）：

I am attempting to use this code sample to control the Windows XP On-Screen Keyboard (OSK.exe) from a C# (.NET 3.5) Winforms application:

[DllImport("User32.dll")]public static extern Int32 SetForegroundWindow(int hWnd);  
[DllImport("user32.dll")]public static extern int FindWindow(string lpClassName, string lpWindowName);
private void BringToFront(string className,string CaptionName)        
{            
   SetForegroundWindow(FindWindow(className,CaptionName));        
}

private void Form1_Load(object sender, EventArgs e)        
{            
   BringToFront("Notepad", "Untitled - Notepad");                            
}

我如何确定准确的className？我假设CaptionName是屏幕键盘

How do I determine the accurate className? I assume that the CaptionName is 'On-Screen Keyboard'.

推荐答案

貌似类名是：OSKMainClass

Looks like the classname is: "OSKMainClass"

下面是我用找到这个代码。这只是一个简单的C＃窗体应用程序

Here is the code I used to find this. It's just a simple C# Forms App

    [DllImport("User32.dll")]
    public static extern Int32 SetForegroundWindow(int hWnd);
    [DllImport("user32.dll")]
    public static extern int FindWindow(string lpClassName, string lpWindowName);
    [DllImport("user32.dll")]
    public static extern int GetClassName(int hWnd, StringBuilder lpClassName, int nMaxCount);
    public Form1()
    {
        InitializeComponent();
    }

    private void button1_Click(object sender, EventArgs e)
    {
        int hWnd =  FindWindow(null, "On-Screen Keyboard");
        StringBuilder buffer = new StringBuilder(128);
        GetClassName(hWnd, buffer, buffer.Capacity);
        MessageBox.Show(buffer.ToString());
    }

从以下来源的激活任意窗口利用API
和的 MSDN GetClassName功能
