The picture field would be of type blob or image. You'd pass in the bytes of the image as a parameter to a stored proc or paramaterised query. You'd try to avoid doing it in VB6, a language that always sucked and has been obsolete for a decade or more.

The error means what it says ( although it's hard to decode when you don't just copy and paste it ). Your DAL is in a dll which is not referenced by your project, so it can't work out what you want it to load.

This is actually harder in WPF, because the logical way to do it, is not to draw on a bitmap, but to keep track of actions and draw them on TOP of your image. At least, that's how I did it when I did it and it was a royal pain

OK - 0 and no value are not the same thing. I suspect Amount_Debit is null and not 0. This code is not C#, I don't know what it is, but I suggest changing your data source to return 0 instead of null, or change the check to also check if it's null.

MVC, for sure. It's amazing. So much better than web forms. As for the rest, I would use Entity Framework, just because it's pretty standard, and it works well. I guess the alternative question is, do you have a ton of stored procs written ? If so, writing a data layer for those procs might...
