VB.net Display Arabic Characters

I have an application originally written in VB6 that properly displayed Arabic characters when running in Vista OS. The application is a front end to either an Access or a SQL Server database. The user can translate the default English text for all text items in the program including Labels, menus, Button text or any screen object text as well as all messagebox text and Crystal Report literal text items. The application was recently rewritten in VB.Net 2005. Now this translated text displays multiple question marks instead of the Arabic characters. The same langauge files are loaded as were with VB6 version of application. What am I missing??

This may be a red herring but it says here that to display them (vb.net) you should load the text into a resource file and read from there. The author has a project you can d/l and view if it helps.
Good luck

Thank you for your comment. It seems to be loading it but just not displaying it properly.

Are you setting the culture also?

Would setting the culture essentially be the same as setting regional setting in the Control Panel? Or is this a seperate application level setting needed in addition to the windows regional settings?

is like an on the fly change for the application while it runs, not a thing that effects the whole PC

OK yes I understand this. The problem is it seems like it would display properly if run on a computer that was configured for Arabic chars. It does not where the VB6 version did. The computer is in use in Egypt. We have also tried in house by confirguring for Arabic through control panel. This also used to work fine in VB6 but does not in .NET 2005.

BTW: non unicode characters of other languages do display properly in .NET version of application so it seems to be a unicode issue. Would using a Unicode font be required? I have heard that if a font is not selected then OS chooses correct font based upon regional settings.

I'll try setting culture programmatically rather than using regional setting for entire computer.

OK that seems to have done the job. Hre is code:

 My.Application.ChangeCulture("AR-IQ")
 My.Application.ChangeUICulture("AR-IQ")
