Configure Component Palette II

Hello,

This was my first question:
In Delphi 6 main menu I choose:
Component --> Configure Palette
Does anybody know how you can export this information
to a file or database?

But I'd like to do more:
Can I get more information about components? (like picture and package information)?

Or is there already a tool to do this?

Greetings,

Wim Baaijens

Hi, I've created a sample Delphi 6 wizard just for the fun. Add the following unit to a designtime-only package, compile and install the package. (You'll have to add designide.dcp and vcljpg.dcp to the requires clause in order to compile.)
After successful installation, a new menu item 'Package info...' should appear under 'Help' menu.
Selecting the menu will save component images to .jpg files and produce a .htm file showing the packages, components and component images. HTH, TOndrej
