Well as of i know, since i'm kind of a newbie into programming you could watch some tutorials related to flash game developing
But you'll have to get started into actionscript to code something in flash.
There are some guides you can search for such as tutorials on youtube or buy the famous " for dummies " book series, but there are more books related to actionscript programming too, that can also teach you about essencial information
There's also a developer's guide from Adobe itself, check if you want, there are codes for basic system managing such as working with dates and times and managing calendars to more advanced stuff
