使用VB6檢測Internet Explorer版本

Question

我正在更新舊版應用程序，它具有一些功能，可以檢測已安裝的Internet Explorer版本，僅用於顯示和錯誤報告，而無需任何組件。 用於IE版本檢測的代碼基本上是來自VBnet-DllGetVersion的代碼：詳細的Internet Explorer版本信息 （作者：Kay-Christian Hansen，VBnet-Randy Birch）。 不幸的是，此代碼無法檢測到大於IE6的IE版本。

因此，我想知道這些天用來檢測Internet Explorer安裝版本的VB6可接受的方法是什么？

謝謝。

Answer 1

您可以訪問注冊表來做到這一點。

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Version.

對於IE 10及更高版本，您應檢查

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\svcVersion.

這是我用來獲取文件版本信息的類：

我四處搜尋，卻找不到任何東西。 由於某種原因有些晦澀。 我確實在有人發布解決方案的地方找到了此鏈接，但我無法使其完全正常運行！ :)我不是真正的vb家伙，所以也許可以。 如果您有興趣，請點擊以下鏈接：

編輯：

我實際上錯過了該頁面底部的一些代碼，並且該代碼似乎在獲取IE版本方面效果很好。 我有點簡化了他的代碼：

Dim oFS = CreateObject("Scripting.FileSystemObject")
Dim version = oFS.GetFileVersion("c:\windows\system32\ieframe.dll")
MsgBox("Your IE version is: " & version)

希望這可以幫助！
