Expanding on the Resources application you created earlier, add two more languages to the form by selecting different culture names from the Language property drop-down list.

Notice the .resx files added to your solution, and the additional directories and assemblies added to your Bin directory.

Look up WinRes in the .NET Framework SDK help file.

Attempt to open the form1.resx file from the Resources application in the WinRes tool. After modifying the form in the designer, save the .resx file to a locale that you haven't used yet. Then modify the code in the form to use the culture you just saved in the WinRes tool.
