在计算机上找到活动窗口. [英] Find the active window on a computer.

问题描述

在vb中有没有一种方法可以找到哪个窗口集中在计算机上?例如，如果IE，Open Office Writer和Photoshop是打开的，那么我该如何以编程方式确定哪一个具有焦点?

Is there a way within vb to find which window has focus on a computer? For instance if IE, Open Office Writer and Photoshop are open, how can I programmatically tell which one has focus?

推荐答案

这将需要一些代码类来实现本机窗口功能，这是C#代码，您可以将其移植到VB

This would need some code class to native window function, here is C# code you can port it to VB

using System;<br />using System.Windows.Forms;<br />using System.Runtime.InteropServices;<br /><br /><br />public class MyClass<br /><br />{<br />    [DllImport("user32.dll")]<br />    private static extern IntPtr GetForegroundWindow();<br />    [DllImport("user32.dll")]<br /><br />    public static void Main() {<br />        IntPtr handle = GetForegroundWindow();<br />    }<br />}
