Hi all,

I built a custom module to parse an Excel spreadsheet using a 3rd party DLL that I added under references within my project. It works great so I packaged it up using Chris' 2012 VS template.

After I installed it on a test DNN site I got an error that suggested the DLL's weren't present so I copied them to the DNN bin folder and the error dissapeared but now I have a new error when I go to file manager:

"Error: File Manager is currently unavailable. DotNetNuke.Services.Exceptions.ModuleLoadException: d:\Websites\DNN7TestInstall\DesktopModules\Admin\FileManager\FileManager.ascx.cs(777): error CS0433: The type 'ICSharpCode.SharpZipLib.Zip.ZipEntry' exists in both 'c:\Windows\Microsoft.NET\Framework64\v4.0.30319\Temporary ASP.NET Files\root\4a47d2ce\741952d6\assembly\dl3\56eca313\00ac241d_86fdcd01\SharpZipLib.DLL' and 'c:\Windows\Microsoft.NET\Framework64\v4.0.30319\Temporary ASP.NET Files\root\4a47d2ce\741952d6\assembly\dl3\3a3423d9\c669538c_172cce01\ICSharpCode.SharpZipLib.DLL'"


A similar error appears on the extensions page as well and deleting the 2 DLL's I manually copied to the DNN bin folder makes the error go away. Unfortunately the error returns on the page with my custom module.

What am I doing wrong? Shouldn't adding the DLL's as references to my project include them when I build the package?

Thanks,
Mark

Wes,

I see that now. There are 2 files with similar names:

ICSharpCode.SharpZipLib.dll

SharpZipLib.dll

The host extensions upload piece needs the latter but I need the former to parse my Excel file.

What can I do to resolve this?

Thanks,
Mark

I don't think it's possible because one DLL seems to pull in the other one (ICSharpCode.SharpZipLib.dll). I know this because I can remove that DLL, recompile my module and it comes back in to the DNN bin folder.

At this point I don't think I can use the DLL I found on codeplex to read Excel files. That's OK as long as I can find something else and I'm open to suggestions if anyone has any.

Thanks,
Mark
