Thank you sneuberg. yes, I did see that. The code is very helpful, but I think this post left me with quite a few questions unanswered about
Did it actually send the data at the end?
Possible in MS Access versions (2007) AND Access 2007 RUNTIME version?
Possible in Windows 10 versions (32 + 64 bit) which did not exist back then in 2012?
Possible to send AND receive UDP in the above environment?
Hopefully someone can confirm they got this to work before I attempt to develop.
UPDATE 7 Sept 2017: After testing the code in the above link, it seems to run without an error, but it appears that no UDP packet is sent. At least my UDP testing tools are not picking any up. I am unsure, but it lookslike the UDP sender IP is 0.0.0.0 with a different port every time it runs. Will try and find out more.
