Adding Files to Zip

 In some projects there might be many files generated which needs to be added as an archive and send to a client or transferred to a specific pre-defined directory. We have ZipCreate and ZipAddDirectory function for this in windev

 ZipCreate

 ZipCreate function is used to create an Archive with the mentioned name.
ZipAddFile
Adds a file (of any type) into an archive 

 ZipAddDirectory
Adds all the files in a Directory to the Archive

     // Create the archive
     ResCreate = zipCreate("MyArchive", "C:\Temp\Archive.zip")
     IF ResCreate = 0 THEN
              // Add a file into an archive
             ResAddFile = zipAddFile("MyArchive", ...
                   "C:\MyDirectory\MyFiles\File.pdf", zipDrive)
             //adds all the files in the directory to the archive
             ResAddDir = zipAddDirectory("MyArchive", ...
                      "C:\MyDirectory\MyFiles", True, zipDrive)
      END
            // Display an error message if the file was not added
      IF ResAddFile <> 0 THEN
             Error(zipMsgError(ResAddFile))
       END

 Extracting Files from Zip

 There may be a need to extract files from Zip. For this we need to open the Zip file using ZipOpen with the filename. ZipExtractAll is used to retrieve all the files from the Zip file and finally close the zip using ZipClose function.

 Example

       // Open an archive
      ResOpenArchive = zipOpen("Archive", sFIleName)
      IF ResOpenArchive = 0 THEN
              // Extract a file to its initial location
   ResExtractFile = zipExtractAll("Archive",fExeDir(),True)

             // Display an error message if the files were not extracted
            IF ResExtractFile <> 0 THEN
                   Error(zipMsgError(ResExtractFile))
   END
    END
   zipClose("Archive")  //close the zip file
