keybd_event() and RDP (Remote Desctop Protocol)

Hi

I need to send characters to a PC from a CE device using the RDP

Characters A-Z and 0-9 is working fine

But , ; : is not sent

keybd_event(&H39, 0, 0, 0) 'key down SENDING 9 OK

keybd_event(&H39, 0, 2, 0) 'key up

keybd_event(&H2C, 0, 0, 0) 'key down SENDING , NOT WORKING

keybd_event(&H2C, 0, 2, 0) 'key up

Heeelp
