Using an external SDK

While I’ve made almost 10 web application of various sizes using Xojo, I’ve never needed to interact with an external site before. I’m looking at starting a project that utilizes the data. They have a lot of excellent examples, including extremely basic ones. One of the examples is below which works perfectly fine if copied into a simple .HTML file. My issue starts when using it within XOJO…

  • I’ve tried using this code within an HTMLViewer using the loadPages event…while the form shows up, the main star field data does not. Not being successful I figured I would look into the Web Control SDK (note…head is spinning trying to figure this SDK out).
  • I’ve read through the XOJO documentation on this, and followed the documentation…my little demo app built from the documentation works great. Applying it to my situation…more head spinning.
  • I’ve looked at the sample applications included with Xojo, and to be honest, I’m even more confused. :frowning:

Does anyone have a suggestion to:
a) helping me get this working
b) more importantly, get my head around the whole web control SDK situation?

Thank you in advance…
