SharePoint 2007 has built-in support for Resource files helping you achieve localization. Using these files you are able to set localized labels for the resources being provisioned.

While working with the SharePoint Solution Generator (a utility which ships with Visual Studio 2005 extensions for Windows SharePoint Services 3.0) I have stumbled upon an interesting by-design feature which affects the way you develop Features - at least if you're using or planning to use the SharePoint Solution Generator (SPSolGen).
I've just stumbled upon a little inconvenience within SharePoint object model. As I needed to programmatically add a new View to a list, I have used the StringToSPViewType method of SPViewCollection class to convert a string representation of the view type to its SPViewType equivalent. Unfortunately all what I've got was an Argument Exception: Value does not fall within the expected range. Using the Lutz Roeder's Reflector I've taken a look into the assembly and I've found the reason of this problem.
