Dotnetnuke module contains of several user controls. Most often each user control has corresponding local resource file to localize the labels.

But sometimes your might want to create a shared resource files to use from two or more user controls.

When you want to get the localized string from the corresponding resource file.

For e.g: Getting the localized string from edit.ascx from edit.ascx.resx

return  DotNetNuke.Services.Localization.Localization.GetString("ItemTemplate",  this.LocalResourceFile);

When you want to get the localized string from the shared resoruce file(other resource file than the corresponding resource file)

For eg: getting the localized string from edit.ascx from SharedResources.resx

string  sharedResourceFile = DotNetNuke.Common.Globals.ResolveUrl("~/DesktopModules/ModuleName/App_LocalResources/SharedResources.resx");
