Some Time Ago…I wrote a blog entry, PE Files, UAC, Reg-Free COM, and Other Crazy Stuff – Part 2, that detailed how to view and edit the application manifest that is inserted into VFP compiled modules. I also took some time to explain why someone would want to do such a thing. The top two reasons most VFP developers want […]

The bug that was fixed pertained to 0 byte (length) files were being ignored when a zip file’s contents were extracted. The Zip routines were handling the 0 byte […]
