posted April 17, 2009 6:45 AM Hallo support, I am currently evaluating the ZIP ActiveX tool. All is working as expected except then Archive Comment. I try the following code: Private Sub Form_Load() Zip1.FileStore.VolumeLabel = "" Zip1.FileStore.Clear Zip1.FileStore.Add "C:\boot.ini" Zip1.FileStore.Comment = "BOOT COMMENT" Zip1.FileStore.Zip "c:\boot.zip" End Sub The comment is not stored to the zip file. Any Idea? Andreas |

posted April 17, 2009 7:13 AM As an addition to my last post: the ZIP Object can read the ZIP Comments written with other products like WinRAR without any problems. Writing comments to ZIPs is the problem. Even you ZIPMan sample displays the comments from other products correct. But after writing ther own comment the string scrambles. I guss the load routine reads the wrong memory area :( Andreas |

posted April 17, 2009 8:37 AM Add 2 :) I have checked the generated ZIP from your tool with a bunch of other UnZIP Tools. Some of them claims error in structur. Perhaps the installed "WebServer for ActiveX" causes some DLL Problems. Here are the relevant DLLs on my system: 2.8.3.0 C:\Windows\system32\DartCertificate.dll 2.8.0.14 C:\Windows\System32\DartMail.dll 2.0.6.0 C:\Windows\system32\DartSecure2.dll 3.1.3.0 C:\Windows\system32\DartServer.dll 3.1.3.0 C:\Windows\system32\DartService.dll 2.8.3.25 C:\Windows\System32\DartSock.dll 2.8.0.6 C:\Windows\System32\DartUtil.dll 1.8.3.0 C:\Windows\system32\DartWebServer.dll 1.8.3.0 C:\Windows\system32\DartWebUtil.dll 1.8.8.0 C:\Windows\System32\DartZip.dll Andreas |

posted April 20, 2009 5:32 PM Hello, I've duplicated this issue and reported it as issue #5068 you can contact Jamie Powell (jamie.powell@dart.com) for information on the availability of a fix. In the meantime I've found that the following code works correctly when setting the comments property of the first file in the archive, so as a work around until this is fixed, you could do this: Private Sub Command1_Click() On Error GoTo OnError Command1.Enabled = False Zip1.FileStore.Clear Zip1.FileStore.Add "d:\test\folder\", True, True Zip1.FileStore(1).Comments = "This is a comment" Zip1.FileStore.Zip "c:\test.zip" Zip1.FileStore.Clear Zip1.FileStore.Load "c:\test.zip" MsgBox Zip1.FileStore(1).Comments GoTo Done OnError: MsgBox "ERROR #" + CStr(Err.Number) + ": " + Err.Description Done: Command1.Enabled = True End Sub |

posted April 21, 2009 5:55 AM Hello Jason, thanks for your reply. But your workaround only stores a file comment. All other ZIP applications did not know anything about this. My other apps are using the ZIP Comment to figure out the contents of the ZIP File. For now I write the comment with another control I bought some years ago. But zipping with your ActiveX is so much faster. I donīt want to miss it :) Andreas |
