Ich aktualisiere eine Legacy-App und es verfügt über einige Funktionen, die die installierte Version von Internet Explorer erkennt, nur für die Anzeige und Fehlerberichterstattung nicht, weil irgendwelche Komponenten erforderlich sind. Der für die IE-Versionserkennung verwendete Code ist im Wesentlichen der Code von VBnet - DllGetVersion: Detailed Internet Explorer Version Info (Autor: Kay-Christian Hansen, VBnet - Randy Birch). Leider erkennt dieser Code IE-Version nicht größer als IE6.Erkennen von Internet Explorer-Version mit VB6

Also frage ich mich, was die anerkannte VB6-Methode der Erkennung der installierten Version von Internet Explorer in diesen Tagen ist?

Danke.

Hier ist eine Klasse-I verwenden Dateiversionsinformationen zu erhalten:

Das sind meine Ergebnisse für IE 8.

Sie können auf die Registrierung zugreifen, um das zu tun.

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Version. 

Für IE 10 und höher sollten Sie

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\svcVersion. 

Blick auf KB 969393

ich um gesucht zu überprüfen und ich nicht wirklich etwas finden konnte. Irgendwie unklar aus irgendeinem Grund. Ich habe diesen Link gefunden, wo jemand eine Lösung gepostet hat, aber ich konnte es nicht vollständig arbeiten! :) Ich bin nicht wirklich ein VBA-Typ, also könntest du es vielleicht. Hier ist der Link, wenn Ihr interessiert:

http://www.visualbasicscript.com/m_64130/tm.htm

Edit:

ich verpasst tatsächlich einen Code auf der Unterseite dieser Seite und dieser Code schien gut zu funktionieren in der Version von IE bekommen. Ich habe seinen Code ein wenig vereinfacht:

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

Hoffe, das hilft!
