It means that there is a [...]

Today we wanna talk about how to achieve translucent Delphi windows with Windows Vista. I know this does not sound like a big deal for all the lucky owners [...]

In this second part, we want to improve our job list (a little bit) and start own dowloads.
The first task is, to replace the old TListbox with a TListview. I switched the ViewStyle to vsReport and added 3 columns: Name, State, GUID. Saving the [...]

Dear Visitor/Delphi programmer,
As the main developer of JWSCL and the author of the most blog posts here, I will retreat from the projects for the next months. At least I will try to fix bugs, write some articles and manage the whole project as a project manager. Don’t expect much from me the next months. [...]
