Filtering keystrokes

[Mahbub]

Friends,

I am from Bangladesh. In our language (Bangla) some alphabets change their shapes according to previous alphabets.

If I want to type Bangla in various applications I must filter each keystrokes i.e.; if a user press "S" key in an application, my application(which is already running) will interpret it as chr(122) or chr(124) or chr(151) [of a Bangla font developed by me] depending upon the previous alphabet and send that character to that application.

Could anyone show me the way?

This probably isn't the best way but it works

If Len(Text1.Text) > 1 Then
    'change S to whatever needs to be before S
    If Right(Text1.Text, 2) = "ss" Then
        'replace the last character with something else
        'if you need to change the last 2 characters then change the
        '1 to a 2
        Text1.Text = Left(Text1.Text, Len(Text1.Text) - 1) & Chr(124)
        'set focus back to the end
        Text1.SelStart = Len(Text1.Text)
    End If
End If

Its probably possible yes...but it will be slower than its C++ counterpart, and it will be hard to write.
