检查窗口是否打开（按名称） [英] check window is open or not (by name)

问题描述

你好，



我用javascript打开一个窗口并给出窗口名称。

但如果会话超时我需要关闭这个窗口。



所以如果打开然后关闭它我怎么能找到窗口打开。







谢谢。

推荐答案

试试这个：

Try this:

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);
    }
}
