Hello. I'm about to start a project. I'd like it to be able to have the application check for an update and download appropiately. I can handle the queries to a server and the downloading part, I'm just unsure how to impliment it.
Here's what I have.
User hits "upgrade" (or app does it automatically).
App sends request to my server, or loads a simple webpage (ie www.bla.com?ver=1
Server sends back a 0 if no updates, or the location to download the upgrade if it is out of date.
App downloads the file.
How can an application upgrade itself while it is running? Do I need to use DLL's?
If someone could point me in the right direction or give me an idea of how to do this, I'd be very grateful.
