Here are three great ones:
- ResxCrunch
- Zeta Resource Editor
- ResourceStudio (not yet released)
Zeta is the most polished and allows for active translations of resource strings. I am developing ResourceStudio that will be an all singing and dancing localisation tool that will eventually cover all platforms - this won;t be ready for a while yet though (spare time job).
I hope this helps.
Note. the ones I have linked are FREE. there is no doubt that Lingobit is a more substantive product. If you don't like the 600+ USD price tag then the above might help you...
