Wayne Golding has been a Xojo developer since 2005. He operates an IT Company Axis Direct Ltd www.axisdirect.nz which primarily develops applications using Xojo that integrate with Xero www.xero.com.  Wayne’s hobby is robotics where he uses Xojo to build applications for his Pi2 often implementing IoT for remote control.

When receiving data from remote sources there are two options available, one option is where the source will send a packet size followed by the data, the other is where the packet is terminated. Today we’re going to look at the terminated version.

But it said DataAvailable…where is all my data?

I’ve seen this a few times and have made the mistake once or twice myself. You write some code with TCP sockets and rely on the DataAvailable event as if it means “all your data is here”.

But it’s not. So the code you wrote that parses the data into its components keels over because you only have part of what you were expecting to have. And so you ask: “Why isn’t all my data here”?

Do you have a suggestion for a feature you would like added to Xojo? Have you found a bug? In either case, the best way to report this to us is to use the Xojo Feedback app.
