使用VB6检测Internet Explorer版本 [英] Detect Internet Explorer Version using VB6

问题描述

我正在更新旧版应用程序，它有一些功能可以检测已安装的Internet Explorer版本，仅用于显示和错误报告，而不是因为需要任何组件。用于IE版本检测的代码基本上是来自 VBnet - DllGetVersion：详细的Internet Explorer版本的代码信息（作者：Kay-Christian Hansen，VBnet - Randy Birch）。不幸的是，这段代码没有检测到大于IE6的IE版本。

I'm updating a legacy app and it has some functionality that detects the version of Internet Explorer that's installed, just for display and error reporting not because any components are required. The code used for IE version detection is basically the code from VBnet - DllGetVersion: Detailed Internet Explorer Version Info (Author: Kay-Christian Hansen, VBnet - Randy Birch). Unfortunately this code doesn't detect IE version greater than IE6.

所以我想知道现在检测安装的Internet Explorer版本的VB6方法是什么？

So I'm wondering what the accepted VB6 method of detecting the installed version of Internet Explorer is these days?

谢谢。

推荐答案

这是我用来获取的课程文件版本信息：

Here is a class I use to get file version information:

Option Explicit
