I'm trying to do something similar in C++.

Our application is localized with regard to our own messages but we
can't control the system messages, so I attempted to use the following
function to return a system message in the language of my choice.

mainLang and subLang are determined by the culture (i.e, "en-us",
"en-gb", fr")
lastError is the last system error that occurred.
I'm preserving it because the first FormatMessage may not work, and
then I'll try it again with the default language.

	wStat = FormatMessage(FORMAT_MESSAGE_ALLOCATE_BUFFER |
		FORMAT_MESSAGE_FROM_SYSTEM, NULL, lastError,
		MAKELANGID (mainLang, subLang),
		(LPTSTR)&pErrorMessage, 0, NULL);

Passing in anything other than the default language results in system
error code 1815: ERROR_RESOURCE_LANG_NOT_FOUND
"The specified resource language ID cannot be found in the image
file."
The error message is misleading since it implies that there is
something
I could do to correct the problem... like upgrading Windows for other
language support.  I would have no problem with that.

However, the following code for FormatMessage tells what really
happens.

  if ( ( dwFlags & FORMAT_MESSAGE_FROM_STRING ) && 
00580          ( dwFlags & FORMAT_MESSAGE_FROM_SYSTEM ) )
00581     {
00582         ERROR( "These flags cannot co-exist. You can either "
00583                "specify FORMAT_MESSAGE_FROM_STRING, or "
00584                "FORMAT_MESSAGE_FROM_SYSTEM.\n" );
00585         SetLastError( ERROR_INVALID_PARAMETER );
00586         goto exit;
00587     }
00588     
00589     if ( !( dwFlags & FORMAT_MESSAGE_FROM_STRING ) && 
00590          ( dwLanguageId != 0 && dwLanguageId != MAKELANGID(
LANG_NEUTRAL, SUBLANG_DEFAULT ) ) )
00591     {
00592         ERROR( "Invalid language indentifier.\n" );
00593         SetLastError( ERROR_RESOURCE_LANG_NOT_FOUND );
00594         goto exit;
00595     }

If you are passing in the flag for a system error, it forces you to
use the default culture. So if your OS is in German and the client
also reads German, then I think you'd be OK.  But say you have
customers in different languages pointing to the same server...??

I can't figure out how to do this, except for trying to change the
default language on the fly, and hope you don't break anything.

Could try Altavista(Babelfish) translation: "the printer name is
inadmissible"
