JCLCompression and 7-Zip - Delphi

[@braaitongs]

So if you add the 7z.dll to your project can you use the LZMA compression method? Dephi's native Zip.pas does not cater for that method.

hi Alistair. Why does the ComboBoxEx blink when hovering over, but the ComboBox does not blink, it works fine. Double buffering doesn't help. Same situation with SpeedButton (blinking), but Button (normal)?

Question: Can you show or mirror another app in a panel in Delphi ?

[@codegearguru]

Nope, this is related to using JCLCompression?

Alister -- I would be very interested to hear your impression of the current state of INDY and JEDI libraries. My brushes with bits and pieces of these libraries years ago gave me the impression that they were well-intentioned but overgrown grab-bags of overly interdependent shovel-ware modules containing code of very variable quality and level of maintenance and abandonment. When trying to import just one feature or library, you couldn't anticipate how much other junk that would suck into the project with high likelihood of those ancillary parts needing troubleshooting or rewriting. This has caused me to stay away from them like the plague, who knows, perhaps unwarrantedly. Do you have present-day assessments of these two projects that might be a bit more encouraging?

[@codegearguru]

I've not used JEDI very much, and usually only small parts of it. But I've used INDY a lot and found it pretty good for most things. Although I often use the native http components frequently now, as they have better built in SSL support that doesn't require a DLL.

@@codegearguru Thanks for your response!

I think that a Book on the main but less explored open source libraries should be very appreciated by the delphi Community I think we have a lot of hidden gems in a not so explored world ...

Stupid to use 7z over JCL, because Delphi have natize ZIP v6 support from the box.

[@bazcuda]

Depends what archive formats you want your application to support. I use 7z and my application supports [reading and extracting] all common archive formats, not just zip.
