Hi Roger,

As state some months ago I try to enhance the GSP a little. First shot is to add a "latest n pictures" box on the main page of GSP. I already added a first draft of the functions to the provider interface, the base class and a SQLite implementation (SQLServer impl. currently returns null).

Now I i tried to get the source-version of the GSP to run from within VS2008 using the Casini webserver. I renamed the x64 binary for SQLlite as I am using 32-bit. Then I've successfully executed the installer from within the VS2008/Casini.

But now I get the error-page (showErrorDetails set to true) that shows me the following error. Maybe you are already aware what could be the problem and give me a hint or two ;-)

Cheers,
Marc

Just recognized that the AppSettings.cs is not a generated code file but your own. Debugging the function DetermineIfDotNet3IsInstalled() show that the following line return NULL.

Code:

Type metadataExtractor = assembly.GetType("GalleryServerPro.Business.Wpf.WpfMetadataExtractor");


so the following line will crash with the above error:

Code:

System.Reflection.MethodInfo addMetadataMethod = metadataExtractor.GetMethod("AddWpfBitmapMetadata", parmTypes);


any ideas?

Just added the following lines between the two shown above:

Code:

if (metadataExtractor == null)
{
return false;
}


Now the gallery runs. But there seems to be a problem loading the assembly GalleryServerPro.Business.Wpf.WpfMetadataExtractor. I am running VS2008 on Win7 Pro with the latest service packs so WPF should be no problem I think. I also use the .net 3.5 web.config. Hmm... Strange.

Any chance you changed the namespace so that GalleryServerPro.Business.Wpf.WpfMetadataExtractor no longer exists?

The other reason for the failure is that the dll named GalleryServerPro.Business.Wpf.dll is not present in your bin directory.

At any rate, if you are sure you will run the code under .NET 3.5 or later, you can modify that code so that it uses a direct project reference to the TIS.GSP.Business.WPF project instead of reflection. I use reflection so that it degrades gracefully in .NET 2.0.

I did not change any namespace yet. Also I like to keep my changes as little as possible to be able to integrate the new features into the standard GSP project (if you like them). So no 3.5 features to use ;-)

Have you checked your bin directory to make sure that GalleryServerPro.Business.Wpf.dll is present?

Well, I am not sure. The only possible causes I can think of are:

1. The dll is not present in the bin directory.
2. The name of the dll has changed.
3. The namespace/type has changed.

As I said before, if you want to get it running, you can always do a direct project reference instead of using reflection.
