Comparator: Compare the Rendering of a Page in IE and Mozilla

Thursday November 13th, 2003

Vazz wrote in to tell us about Comparator, a Windows tool for comparing the rendering of pages in both Internet Explorer and Gecko. A Comparator preview release is available from the Comparator GotDotNet Workspace. It requires the Microsoft .NET Framework Version 1.1, Mozilla and Internet Explorer.

This has been done in HTML-Kit which has no framework requirement. Just register a Mozilla control - from netscape 7 even - and you can see the page rendered in both IE and Gecko side by side. But Comparator uses it in the .Net environment. I've gotten the control to work in a simple Visual Basic.Net 2002 program.

Malc: Comparator uses the Mozilla activeX control. It needs to be registered to work and mozilla does not do that for you. I have not tried Comparator though. I used netscape 7's Mozilla control for HTML-kit. For Mozilla 1.4+ the control will be found with the GRE. My Moz 1.4 control was in: C:\Program Files\Common Files\\GRE\1.4f_2003062408.

I also see the control with Kmeleon 0.8 and Moz Firebird 0.7. So they may work too.
