Topwiz Software - ZLibwapi

Free Code

All examples include a PB10.5 version and most have a PB12.6 version. The PB12.6 versions are verified to work in 64bit. PowerServer doesn't support the longptr type so you must use the PB10.5 version in that environment. If one of the examples doesn't work correctly, please contact me first before posting to the Appeon user forum or bug tracking system.
