I'm writing a module that takes a .zip file via the standard Upload control and I want to unzip the contents into a defined TemplateSourceDirectory subdirectory.

I tried to use DotNetNuke.Common.Utilities.FileSystemUtils.UnzipFile(Me.FileUpload.FileName, path, Me.PortalSettings) where 'path' was 
Me.TemplateSourceDirectory & "/" & Category & "/" & TargetFolder [I discovered that it wanted a virtual path, not a real one using server.mappath]

This returns "startIndex cannot be larger than length of string. Parameter name: startIndex" which doesn't appear to relate to anything at all....

I then used this: DotNetNuke.Common.Utilities.FileSystemUtils.UploadFile(path, Me.FileUpload.PostedFile, True)

and I get the following error: "An Error Has Occurred When Attempting To Save The File xxxxx. Please Contact Your Hosting Provider To Ensure The Appropriate Security Settings Have Been Enabled On The Server." As thisis on my local dev machine, all permissions are wide open....

Anyone any ideas?

PS. I had a little trouble earlier, working out exactly what the parameters related to... is there a DotNetNuke API 'Map' with sensible descriptors  of the API, (and as a bonus, code examples would be great), - I have ALL the Dotnetnuke books and there's nothing in these that help....

regards,
Duncan.
