Question

I have DotNetZip installed and running fine on a Windows 2008 server.

Using a classic ASP page, I want to bundle a bunch of comma-delimited files to a user and send it over in a zip file.

The following code works fine but it stores all the path information so the files inside the zip file are located in some ridiculous directory like C:\Inetpub\wwwroot\appname\_temp\

I’m using the following code:

Set objZip = CreateObject("Ionic.Zip.ZipFile")
sFileArray = Split(sFileArray, "|")
For iCount = 0 To UBound(sFileArray)
If sFileArray(iCount) <> "" Then
objZip.AddFile sFileArray(iCount)
End If
Next
objZip.Name = sFilePath & "test.zip"
objZip.Save()
objZip.Dispose()
Set objZip = Nothing

I see that the AddFile method allows you to specify where you want the added file to reside in the zip file if you add a second parameter. According to the documentation objZip.AddFile sFileArray(iCount), "" should put the file in the root of the zip file.

However, when I add that parameter, I get the following error:

 Wrong number of arguments or invalid property assignment: 'objZip.AddFile' 

Anyone have any idea what I’m doing wrong?

Thanks.

I think you are misinterperting the documentation. If the second parameter is null then the directory path of the file being added is used. If the second parameter is an empty string “” then the file is added to the root level in the zip. A quick look into the Ioniz.zip.dll shows that the single parameter override of AddFile method simply calls the the double parameter override with the second parameter set to null.

Hence your add file should look like:

objZip.AddFile sFileArray(iCount), ""

to get the result you are after.
