(AutoIt) Zip Append Files and Entry TypeSee more Zip ExamplesDemonstrates appending files to a zip object for writing a .zip. Also explains the "entry type".
; This example requires the Chilkat API to have been previously unlocked. ; See Global Unlock Sample for sample code. Local $bSuccess $oZip = ObjCreate("Chilkat_9_5_0.Zip") Local $oEntry Local $sZipPath = "c:/temp/qa_output/out.zip" ; Initialize the zip object with the path of the .zip to be created. $oZip.NewZip($sZipPath) ; Recursively append to the zip object the paths of the files and directories in a directory tree. ; At this point we are not creating the .zip, nor are we reading the contents of the files. ; We are simply appending references to the files and directories in the local filesystem ; that will get processed when WriteZip is called. Local $bRecurse = True Local $bSaveExtraPath = False Local $bArchiveOnly = False Local $bIncludeHidden = True Local $bIncludeSystem = False $bSuccess = $oZip.AppendFilesEx("c:/temp/files_to_zip",$bRecurse,$bSaveExtraPath,$bArchiveOnly,$bIncludeHidden,$bIncludeSystem) If ($bSuccess = False) Then ConsoleWrite($oZip.LastErrorText & @CRLF) Exit EndIf ; Note: We can iterate over the references to the files that will be processed when zipping: Local $iCount = $oZip.NumEntries Local $i = 0 While $i < $iCount $oEntry = $oZip.GetEntryByIndex($i) ConsoleWrite($oEntry.FileName & " entryType = " & $oEntry.EntryType & @CRLF) $i = $i + 1 Wend ConsoleWrite("----" & @CRLF) ; Sample output for the above loop: ; The entry type = 1, because these are entries that are references to files in the local filesystem ; that are to be processed when the zip is written. ; hamlet.xml entryType = 1 ; hello.pdf entryType = 1 ; ... ; ... ; Possible entry type values: ; 0 - Mapped Entry: An entry in an existing Zip file. ; 1 - File Entry: A file not yet in memory, but referenced. These entries are added by calling AppendFiles, AppendFilesEx, AppendOneFileOrDir, etc. ; 2 - Data Entry: An entry containing uncompressed data from memory. These entries are added by calling AppendData, AppendString, etc. ; 3 - Null Entry: An entry that no longer exists in the .zip. ; 4 - New Directory Entry: A directory entry added by calling AppendNewDir. ; The application can continue to add additional entries. ; For example: Local $oETemp = $oZip.AppendString("helloWorld.txt","Hello World") ; Now let's have a look at what will get zipped when we write the zip: $iCount = $oZip.NumEntries $i = 0 While $i < $iCount $oEntry = $oZip.GetEntryByIndex($i) ConsoleWrite($oEntry.FileName & " entryType = " & $oEntry.EntryType & @CRLF) $i = $i + 1 Wend ConsoleWrite("----" & @CRLF) ; You can see that "helloWorld.txt" is added. ; Its entryType = 2, which means it is in-memory data (it is not a reference to a file in the local filesystem). ; hamlet.xml entryType = 1 ; hello.pdf entryType = 1 ; ... ; ... ; helloWorld.txt entryType = 2 ; ---------------------------------------------------------------------------- ; Now we'll write the zip to a .zip file. $oZip.FileName = $sZipPath $bSuccess = $oZip.WriteZip() If ($bSuccess = False) Then ConsoleWrite($oZip.LastErrorText & @CRLF) Exit EndIf ; Let's look again at the entries in the .zip $iCount = $oZip.NumEntries $i = 0 While $i < $iCount $oEntry = $oZip.GetEntryByIndex($i) ConsoleWrite($oEntry.FileName & " entryType = " & $oEntry.EntryType & @CRLF) $i = $i + 1 Wend ConsoleWrite("----" & @CRLF) ; After writing the .zip, the entry types change to 0. ; Entry type 0 indicates that it's a "mapped entry", which is an entry in an existing (and currently open) .zip file. ; hamlet.xml entryType = 0 ; hello.pdf entryType = 0 ; ... ; ... ; helloWorld.txt entryType = 0 ; ---------------------------------------------------------------------------- ; If desired, we could continue adding additional entries of any kind (files or data) to the currently open .zip archive... $oETemp = $oZip.AppendString("helloWorld2.txt","Hello World 2") ; Write the .zip, including the new entries.. $bSuccess = $oZip.WriteZip() If ($bSuccess = False) Then ConsoleWrite($oZip.LastErrorText & @CRLF) Exit EndIf ; Finally, let's look again at the entries in the .zip $iCount = $oZip.NumEntries $i = 0 While $i < $iCount $oEntry = $oZip.GetEntryByIndex($i) ConsoleWrite($oEntry.FileName & " entryType = " & $oEntry.EntryType & @CRLF) $i = $i + 1 Wend ConsoleWrite("----" & @CRLF) ; hamlet.xml entryType = 0 ; hello.pdf entryType = 0 ; ... ; ... ; helloWorld.txt entryType = 0 ; helloWorld2.txt entryType = 0 $oZip.CloseZip ConsoleWrite("Success" & @CRLF) |
