I know this might sound a little strange, but being a dual language speaker, sometimes I don't know the word in my other language, and thereby use the English word. (I believe people refer to this as Double Dutch)
Perhaps restricting the allowed characters is not a good idea?

As i mentioned that i am using vb.net 2010 and i have a window application, it is going to be used in Arabic language and as well as in English language for English language i have done the validation rule like below is my code. what is my problem is that i want to do the same validation rule for Arabic language that the user may not be able to write numeric value in textbox where only text is allowed and viceversa text should not be written in the textbox where only numeric value is allowed to be thanks.

Private Sub txtTrnCnt_Name_KeyPress(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles txtTrnCnt_Name.KeyPress
If (Microsoft.VisualBasic.Asc(e.KeyChar) < 65) _
Or (Microsoft.VisualBasic.Asc(e.KeyChar) > 90) _
And (Microsoft.VisualBasic.Asc(e.KeyChar) < 97) _
Or (Microsoft.VisualBasic.Asc(e.KeyChar) > 122) Then
'Allowed space
If (Microsoft.VisualBasic.Asc(e.KeyChar) <> 32) Then
e.Handled = True
End If
End If
' Allowed backspace
If (Microsoft.VisualBasic.Asc(e.KeyChar) = 8) Then
e.Handled = False
End If
End Sub

Try using the Unicode codes to validate the input. Look at Wikipeadia for the unicode ranges. You will have to work out what is Letters and what is numbers.
Have you thought of a virtual keyboard with the letters only typing in the letters box and visa versa?

Just Validate the Arabic in Unicode. Keep the ASCII for the English
