Subject Re: Need urgent help with serialization problem
Date Wed, 26 Jun 2002 17:38:53 GMT
Alpa,

You have a working example for Int. Can I see that code if you do not mind.
Scott Sealy of Microsoft has a different example for sending/receiving String. If you want
you can contact him.

Thanks,

Indrasish.
