arabic not joined in non-arabic windows xp

[Philip]

Hi everyone,

i have develped an application in C# with arabic in Labels and listboxes, it
works fine in vista and in xp machines where arabic language is installed.
However if i run the app in xp with no arabic language installed, it shows
separate arabic characters instead of the joined cursive writing. I know this
is an OS problem and not specific to my app because if i type something in
arabic in notepad in a vista system and take it to the xp system without
arabic, it does not display correctly.

How can this be done? I looked around for a few days for solution but to no
avail. I tried to programatically install arabic fonts and used that font in
my app but it dosent work. I got some 3rd party components to do the job but
they dont have the grid which i need in my app.

The thing is that I have seen a different app and it works fine in
non-arabic xp but i dont know how they have done it.

Can anyone help? I tried for days!!

Thanks
Philip

I would like to repro, which Framework are you using?

Hi Phil,

You need to files for Complex Script and Right to Left languages in. Have
you done that? You can do it from ControlPanel/RegionalSettings/Language tab.
Have your Windows CD ready.
