如何在VB.net中以編程方式關閉窗口？

Question

如何在VB.net中以編程方式關閉外部應用程序的窗口。 我只想關閉當前窗口而不關閉整個過程。

Answer 1

使用FindWindow和SendMessage API

這里用C＃，應該是微不足道的轉換：

using Microsoft.Win32;

[DllImport("user32.dll")]
public static extern int FindWindow(string lpClassName,string lpWindowName);
[DllImport("user32.dll")]
public static extern int SendMessage(int hWnd, uint Msg, int wParam, int lParam);

public const int WM_SYSCOMMAND = 0x0112;
public const int SC_CLOSE = 0xF060;

private void closeWindow()
{
    // retrieve the handler of the window  
    int iHandle = FindWindow("Notepad", "Untitled - Notepad");
    if (iHandle > 0)
    {
        // close the window using API        
        SendMessage(iHandle, WM_SYSCOMMAND, SC_CLOSE, 0);
    }  
}
