Ruschmeyer Monika. Monday, January 4, at PM Great. Items; but does fine under Gabriel Jim. Their solution was to enclose the variable string with brackets e. Using brackets on all the strings passed as arguments now allows me to use this code in Delphi 7. I hope this info will be useful to others experiencing a similar problem. Geoff Bacon.

Many events have modifiable parameters to allow your application to change file parameters or specifications as the files are being zipped, unzipped, converted, etc. Provide feedback to the user when the temporary zip file is being copied to its final destination.

Wildcard previewing: find out exactly which files will match your wildcards and filters before you start zipping or unzipping. Compression previewing: obtain the compressed file sizes before starting the actual zipping operation.

Statistics on the entire group of files to be zipped are also provided. Filter out files during a zip file update, merge, or conversion based on any file attributes or parameters. All exported API calls involving string parameters come in single, wide character, and Unicode versions. Create new self-extracting zip files or transform already existing zip files into self-extracting zip files. Execute one or more applications optionally with parameters or open documents after successfully unzipping files.

Create self-extracting zip files with a built-in decryption password. This prevents users from using unzipping programs to unzip the files, and therefore forces users to view your custom introduction, license agreement, or warning messages.

Allows 3rd-party install or setup programs and their data files to be unzipped into a temporary folder, executed, and then deleted upon completion. Custom paths, filenames, strings, and prompts are parsed, allowing you to insert strings such as the current folder, windows and windows system directories, the temporary folder, and more. Supports the Zip64 zip file format allowing the creation of Zip files of practically unlimited size no more 4 GB limit , which can contain a practically unlimited number of archived files.
