I am using Momentics IDE 6.3.2 and PhAB version 2.03. I need to develop a GUI in two languages,  English and German. 
Following the PhAB tutorials for International language support, I could achieve what I want (only on PhAB IDE)  but 
when I am trying to do the same on Momentics IDE, Its not working. Following is the code i referred to-

ApDBase_t *mytext_db;

/* Open the text database. */
mytext_db = ApOpenDBaseFile( "/fullpath/mytext_db.wgtp" );

/* Set the translation to German. */
ApSetTranslation( "de_DE" );

/* Append the external German translation file to the
   current list. This will read the translation file
   "/usr/photon/translations/mystrings.de_DE" and append
   it to the application's current translation list. */

ApAppendTranslation( "mystrings", "de_DE" );

/* Get a translated text string. */
text = ApGetTextRes( mytext_db, "msg001" );

I tried setting the ABLPATH & ABLANG environment variables also.

Can someone help me about what is going wrong?
