>> Would it really be as fast as writing some printing statements and such, Daved?
It's faster (at least for me).
If you've got a small app and you're already running through VC++, just hit F10 (step over) instead of Run (F5) or Execute (Ctrl-F5). Open and dock the Autos window (Debug > Windows > Autos). If your program has output and you have enough room on your monitor (two monitors helps) then put the console or other window next to the debugger, otherwise it will have to be hidden which isn't ideal for this simple exercise.
Then hit F10 to step over each line of code. When you get to a function you wrote, you can use F11 to step into it, then continue with F10. Watch the variables in the Autos window as they change. That's pretty much what the print statements are doing. The difference is you can see it for every line the first time, instead of adding a few statements and then narrowing down the location.
