Hello,

I am trying to implement using Indy components a simple utility that 
will receive UDP data from a data transmission service.

The transmission service simply sends UDP packets to a specific IP/port. 
It does not listen for or expect any type of query or response. The 
other end of the connection was not developed with Indy (not that that 
should matter, I wouldn't think).

I'm not having any luck getting it to work using Indy components. I have 
no trouble making it work with Fastnet components but as I think Fastnet 
is not included with more recent versions of Builder, and we intend to 
upgrade in the not-too-distant future, I don't want to use Fastnet.

I'm sure there is a simple solution to this, but can't figure out what 
it is. Any help as to what component(s) and methods I should use would 
be greatly appreciated.

You did not provide very much information, but basically I would put a 
UDP Server component on the form, set it for the correct port, write 
some code in the listener, make it active, compile, run, and go jogging 
a while waiting for the sender to send the message.

Use TIdUDPSever for that.  Its OnUDPRead event will be fired when data 
arrives.
