SMPP unbind PDU

Hi very useful component!

Maybe I could get your thoughts on this...

The SMSC sends me an error when I unbind "message length is invalid". Apparently, the unbind PDU contains 17 Bytes, with an extra Byte with HEX value 34 at end of the unbind PDU.

I contacted the SMSC I was trying it with, and they said it should be 16 bytes not 17. Is this something I am doing wrong or does the unbind command definately send 17?

I was using 1.2.0.0 of ALT.SMS.SmppClient.

Cheers for any help you may give me,
Ollie

Hi,

Firstly, thanks for the reply.

I have just tried that but cannot add a reference to the latest download with VB.net 2003, so I can't use the latest download.

Is there a work around?

Regards,
Ollie

Sorry,
Since version 2.0.0 we do not support .NET 1.1 any more.
Please consider to upgrade your application to .NET 2.0.

Or you can order source code and modify it, so that it can work with VB.NET 2003.
