Re: Sending Struct is not working ?

Hi,

thanks for the reply. I used existing code - the one given in the
examples of xmlrpc. Unfortunable I was not able to find a C/C++
clients which meets my needs. So I tried to develop my own client
based on the simple client given in the examples ... 
It is still not working. The struct building is no working
correctly... any ideas ?

Cheers
