Now here's the mystery: Why are so many sites that require Flash Player versions 8 and 9 or better failing to detect Flash Player version 10? And here's the juicy background, in technicolor screen captures in my post, "WTF: The Adobe Flash Version 1x Crisis." UPDATE 2: I have since

Reliable way to get Windows Version from registry

由 白昼怎懂夜的黑 提交于 2019-12-17 12:21:12

Is there another reliable way in registry to detect Windows 10? 回答1:

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).

Does anyone know of a good place where I can find the complete list of version defines for all the Delphi versions, right up to Delphi 2009? ulrichb A very, very good Delphi version include file is the jedi.inc from the the JEDI Code Library ( JCL ).
