The Abbrevia 3.04 documentation is available as PDF and HLP files here: https://sourceforge.net/projects/tpabbrevia/files/Documentation/3.04/ When TurboPower open sourced the library they didn't include whatever files they were originally using to generate the help, so it's never been updated. If you stick to the high-level components (e.g., TAbZipKit, TAbZipBrowser, etc), there haven't been many significant changes to the API since then, aside from changing various declarations from "string" to...

Hi there, I am a seasoned C++ programmer. Can anyone tell me how to obtain docos for the Abbrevia compression software ? On the official site, there aren't any links. Thank you, Colin

Good afternoon to all, there is a way to full abort the (de)compression process? If i click to the "abort" button and set to true Aborted variable, in the ArchiveSaveProgress event the Abort variable is for each file. So when Abort is true only that file is aborted .... my need is to stop (abort) all and exit from save proceudre. It is possible? Thank's for reply Daniele

I installed the latest version of Abbrevia but I didn't find any example of buying to create a compressed file or how to unzip using LZMA. It would have an example for me. Grateful.

Hi, I have a compresses stream generated by a another application that uses Abbrevia and I have to decompress it using a C# application. The stream doesn't have any header and every c# library say that the stream is not recognized. What can I do? Is there a compiled utility tu use as external application? Regards G.

Unfortunately, Abbrevia doesn't support encrypting file names because the zip format originally didn't. When they added encryption support to the zip file format it was only defined for the file data, not the file names, and could actually vary from file to file. Newer versions of the spec do include extensions to encrypt the file names too, but it's not well supported (even WinZip only does the file data). You'll need to either encrypt the file as a separate pass with another library or switch to...

Can anyone tell me the simplest way to implement a password on the AbZipKit? I just want to have a password on any given zip file so it won't open easily outside of my application. In the application I want to ask for the password and then open the archive in my app. It doesn't have to be super secure, just enough to keep casual users out. I can put a password in the AbZipKit properties or set it in code but the AbZipKit archive file always opens and never asks anything (I have a simple ShowMessage...

Hi Jay, The version of Abbrevia included in GetIt is based on the fork here: https://github.com/TurboPack/Abbrevia/commits/master I've never been involved with it, so I'm afraid I can't provide support for whatever changes they've introduced. Looking through their repository history, I do see changes related to removing "AnsiString" usage in 2014 that touched the "Password" property and that may have broken things. The current release of Abbrevia here was designed to be forwards compatible with later...

...repeated Load/Modify/Save/Close isn't something I've tested heavily. Neither have I. For now, I've modified that routine to only save/close/load when the threshhold is near. We will see if this stops this behavior at the customer's site. I did not see any Extended characters in the filenames. I think my best option is to refactor the code and stop the continual close/open routine. If this continues, I'll be back. Thanks for your feedback. I really appreciate your time. Best
-
That should work, though repeated Load/Modify/Save/Close isn't something I've tested heavily. You might try freeing the zipper and re-creating it rather than just reloading it to see if there's something being cached. If it's specific customers that are reliably seeing it (on the same files?) my guess would be something about the filenames. Extended (non-ASCII) Unicode characters, perhaps? It's been quite a while since I've worked on Abbrevia, so I can't offer much more than that. If you can get...
-
or updating an existing one? It started as new, but I repeatedly save it to get the file size. Past results during add would not give file size on Win7 machines unless saved (that behavior hasn't been tested lately). Also saving across network can give odd results with the file save/size routines. Here is the loop: repeat if ((sr.Attr and faDirectory) = faDirectory) then Continue else begin if (CompareText(ExtractFileExt(sr.Name),sDotPDF) = 0) or (CompareText(ExtractFileExt(sr.Name),sDotCSV) = 0)...
-
No. Are you adding files to a new zip or updating an existing one? The crash seems to indicate that the contents of an existing zip are corrupt in a way that affects saving but not loading the directory listing. The files you're adding probably isn't a factor unless there's something unusual about them (size, filename, is a symlink, etc).
-
because the header before the compressed file stream is corrupt Thanks Zoë. So you are saying that I'm adding a corrupted file, and the header of that corrupted file is what is invalid and can't be read during that save, correct?
-
Zip files include metadata about the contained files in multiple spots: (1) Immediately before the compressed file's stream, and (2) as part of a directory listing at the end of the file. When you load the archive Abbrevia can read just the directory listing at the end and see all of the files in it, and if you try to access a specific file it can jump straight to that file's header and compression stream without looking at anything else in the file. The error your seeing is occurring because the...

The version of Abbrevia included with recent versions of Delphi is from the fork at https://github.com/TurboPack/Abbrevia Back when it split off the changelog mentioned fixing some sort of issue with C++Builder, but they wouldn't tell me what changed, and I haven't looked into more recent releases, so you'll have to ask there for assistance.

Converting program from XE2 to 10.2 C++ Builder. Old program used manually installed Abbrevia. Abbrevia 10.3 came with Studio 10.2 and I installed it using defaults. I want to use TCabKit and TMakeCab. Components are in palette.. Placed on a VCL form in a package, not main program. Compiles; functions find the methods they want by pointeers to the compoents. Linker says 'Fatal: Cannpt find AbBase.obj' There IS no such file in the installation. How do I fix this, please.

Hello: Can anybody help for Abbrevia for C++Builder XE6? Thanks, Sud
-
I'm not really working on Abbrevia anymore, so aside from unofficial forks like Roman Kassebaum's Get It version, there isn't any active development going on. As a feature request, even if I was more active, it would be hard to justify this change since it would break compatibility for a ton of the API and make it more difficult to use for plain TStreams. If you can use IStream instead, it probably wouldn't be difficult to write a wrapper that converts from it into a TStream, like TStreamAdapter...
