And that is why I mentioned those three books, which are good for initial reading when you
start from nothing. The key concepts (there are more aside OO methods), e.g. QBE and DML excluding each other -> System Modes, or block basing methods etc.,
need to be explained in that situation. Whithout that, a beginner will not understand anything how Forms works ... and that took about half a year for me that time.

After beginnings when starting developing forms, I used more and more the Online Help - it is hard to read and even harder to understand
(well I havs no idea how it changed in 9iDS ...), but You can enter a keyword and read some topics on it. The online help is just the opposite of the books: almost no concept explanations, just tiny atomic tips. Can be quite confusing !

The rest of the work is trial an terror, unfortunately ... it just depends how fast you can manage to judge
which of the 200+ built-in triggers (and 200+ functions) to use for your problem to solve.

P.S. I am still learning, doing forms for 1 1/2 year now, all on my own ... I had no chance to take courses in it.
Luckily I have some fellows in my team (and: this NG !) sharing some experiences.
