我试图用这个code sample从C#(.NET 3.5)的WinForms应用控制Windows XP屏幕键盘(OSK.exe):查找屏幕键盘的类名?

[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");        
} 

如何确定准确的className?我假设CaptionName是'屏幕键盘'。

貌似类名是:“OSKMainClass”

这里是我以前找到这个代码。这只是一个简单的C#窗体应用程序

[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()); 
    }
