After creating the language file for the .uir, open the easytab.c file, and replace the LoadPanelEx call with a call to LoadLocalizedPanel. Afterwards, simply regenerate the .obj file (Options>>Create Object File) which will allow CVI to use the modified .obj each time the .fp file is loaded.
If you want some additional logic behind the call, so that it doesn't always load a particular language, you might have to make some more modifications in easytab.c. You can modify it at will, just be sure to save the .obj file whenever you do.
