For both questions you can quite easily read the MSDN documentation for each function, which explains what they do and what are their inputs and outputs.

Thanks a lot.That makes a lot of sence.I'll do just that..I guese with time I will know from experience which function uses logical points and which one uses device point.But isn't there a rule of thumb of some sort than one can use to tell.Checking documentation for every single function could drastically increase development time.

I'm not sure there is a simple rule of thumb, it's just a question of learning (or learning where to look) the different functions. Given the size of the Microsoft support libraries it is quite difficult to remember them all.
