I see that you provide German, French and Dutch resource files. How can I use them in my app?

There are two ways:

simply include "gxresdeu.rc" into your applications resource file. Then there is no need to ship gx##deu.dll

Build gx##deu.dll and call GXInit("Deu") in your InitInstance method. Calling GXInit("Deu") only works when you are using OG as shared Dll.

Be sure not to include gxres.rc in your applications resource file when using GXInit("Deu"). Otherwise gxres.rc will be used for looking up resources.
