I've recently decided for my VB final that I'd like to tackle something my professor and I discuss constantly; portable game server apps.
What I'm wanting to do, essentially, is create just a rudimentary programme that allows you to check the server status of either the north American or European servers for the game Rift and just (instead of opening your default browser, which I know how to do already) displaying the info in a listbox inside the programme itself.
The information I have to work with (aside from the obvious direct .php link to the web page) is two separate .xml links that contain all the information that is contained on their webpage. I could easily just turn these .xml files in an access database but I want something dynamic rather than static, but I honestly have no clue of how to turn this info I have into something I can actually use in my programme lol.
I'm creating a system (for a project) that is based on a vet.I want to create a combo box that has a list of different animals (e.g. Dog or Cat etc.)and when an animal is selected,a group box, with loads of checkboxes inside appears. Then the user can tick a check box (a vaccine to be given to the animal) and the record is saved to a database.I have hard coded this to work, but I want a more sophisticated code set, that links to SQL so that when a new vaccine is to be added, I would only need to add it in a table, in the database. I don't know where to start for this could any one give me a nudge in the right direction?

Explicit run-time linkingDLL files may be explicitly loaded at run-time, a process referred to simply as run-time dynamic linking by Microsoft, by using the LoadLibrary (or LoadLibraryEx) API function. The GetProcAddress API function is used to lookup exported symbols by name, and FreeLibrary — to unload the DLL.
