VFPCompression Update - Relative Path Fixes

VFPCompression Update

This update contains fixes to problems surrounding relative paths when compressing folders and files that are not relative to one another or the zip file being created. Previous to this version developers needed to send in .T. for the lIgnorePath parameter when calling functions in order to zip files and folders that were not relative. This was not an acceptable workaround as the relative pathing for subfolders would then be ignored as well. This has been a stumbling block for some in implementing this FLL, so I am glad it is finally fixed and sorry that it took so long for me to address this problem.

Special thanks go out to Sergey Berezniker and Elliot Selick. They independently reported the relative pathing issues and helped with testing once I had addressed the issues.

Sample code for using the library and the library documentation can be found in my previous post. Here's the customary download link...

When I create a zip file I define a comment. Can we have functions to set and get the comment for the zip file. And while your at it can you add ability to define comment for a file being zipped (I don't do that).

Hi Craig--first, let me say thanks for the great tools that you have provided to the VFP community. Second, I found a small quirk with the vfpcompression.fll. I was using the ZipFolder function, and I could not get it to respect my relative paths regardless of what I passed for the lIgnorePaths parameter. I finally found that when I removed the trailing backslash from the folder path, it works correctly.

VFPCompression.Fll is a very nice tool.

Does VFPCompression.fll require the installation of any compression software OR does it utilize its own compression routine?

Can I freely distribute the FLL with my applications?

Thanks, Craig. The relative pathing problem was preventing me from using this tool as much as I'd like. How can I keep up with updates? I don't really subscribe to blogs - it's just too distracting and I have enough distractions already. It would be nice to subscribe to updates for particular things.
