Hello!

I'm from Hungary, and I love the SWAG!

It's a very useful site, and I use it since 2 years.
I send to You a Delphi 2.0 component:
 - TLCDControl (it looks like WinNT 4.0 Task Manager's LCD)
      resource file included (XX3402)

This component was made for Delphi 2.0, but it is also working on Delphi 1.0
(I think).
I send it to You, because I don't know any other addresses about SWAG.
I hope, this component will be useful for somebody.

Kind regards
        Matthew Csulik
        matthew-c@usa.net

P.S.: To extract the resource file, use WinZip95 (the 32bit version)!
