[[TableOfContents]] | The class "WinZip" relies on an installed version of [[http://winzip.com/win/en/index.htm |WinZip]] '''and''' the command line extension. If both are installed on your machine then will will have the two executables `WZZIP.EXE` (for zipping) and `WZUNZIP.EXE` (for unzipping) somewhere, typically in C:\Program Files (x86)\WinZip. |

The Windows API methods provided to read a particular value have an advantage: they follow a clearly defined search path, and following that path they take not only the INI file into account, they also check the Windows registry and the command line parameter. Furthermore, they deliver always up-to-date values. | == Examples == |
Line 9: | Line 25: |
They have disadvantages as well: * They are slow * They return everything as a string If you are not interested in the Windows registry and command line parameters, and if nobody else is changing your INI files while your application is running, then the "!IniFile" class introduced in this article might attract your attention. This class allows you to use a kind of APL-Syntax in your INI files. Values not enclosed in quotes will be converted to numbers, everything else gets a string. == Details == === Character Values === An entry like: {{{HomeFolder='C:/Windows/Appl/'}}} results in a string holding the path. === Numeric Values === An entry like: {{{FormSize=300 400}}} results in a two-element-vector "!FormSize" holding two integers. === References === Furthermore, an entry like: {{{LogFolder='{"HomeFolder}Logsfiles/'}}} is treated in a special way: the name between the curlies is taken as the name of an already defined value. It is then replaced by the value of that entry. == Example == === Creating an Instance === After creating an instance from the class: {{{MyIni←⎕New #.IniClass (,⊂'C:/Appl/Example.ini')}}} === Accessing Data with the "Get" method === you can get all information you are interested in by calling the method "Get". Note that names are '''not''' case sensitive. Given this file "Example.ini": |

WinZip
WinZip is part of the CategoryAplTree project.
Warning
Note that WinZip issues an error when you pass something like this with the flag to preserve the directory structure:
C:\My\folder1\file.txt C:\My\folder2\file.txt
According to the company behind WinZip this is nit a bug but by design. Therefore WinZip will issue a DOMAIN ERROR if you have to files with the same name in your list of files to be zipped.
Overview
The class "WinZip" relies on an installed version of WinZip and the command line extension. If both are installed on your machine then will will have the two executables WZZIP.EXE (for zipping) and WZUNZIP.EXE (for unzipping) somewhere, typically in C:\Program Files (x86)\WinZip.
The class makes it very easy to zip as well as unzip stuff.
Examples
Zip all files in C:\MyFolder\ recursively into myZipFile.zip:
(rc more)←#.WinZip.Create 'C:\MyFolder\*' 'myZipFile.zip'
Zip two files nto myZipFile.zip:
(rc more)←#.WinZip.Create ('C:\file1' 'C:\file2') 'C:\MyZipFile'
Unpack C:\MyZip.zip into C:\MyUnzippedFiles\:
(rc more)←#.WinZip.Extract 'C:\MyZip.zip' 'C:\MyUnzippedFiles\'
