Question

我正在尝试使用此code sample从C＃（.NET 3.5）Winforms应用程序控制Windows XP屏幕键盘（OSK.exe）：

[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'。

看起来类名是：“OSKMainClass”

以下是我用来找到这个的代码。它只是一个简单的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Activate Any Window With API获取此信息和MSDN GetClassName function

查找屏幕键盘的类名？
