Dynamically positioning a form/dialog, whilst also keeping it all on one monitor/screen

I've been programming in various languages since 1980. I started in Basic at college and moved swiftly to Z80 assembler. After that I was an operator on a Burroughs mini for a time, then after a little Burroughs COBOL I moved to UNIVAC COBOL for many years. (During which time I became an IT contractor). During that time I touched UNIVAC assembler a bit, as well as the usual SSG etc. I did a bit of RPG, though I never really liked that. After COBOL I went to Gupta SQLWindows for a few years (which I still maintain was a good OO language). Then a move to Oracle PL/SQL and a few years as senior programmer for a large American company, also some years in the DBA team at then end of my time there. Somewhere in the middle of that I spent a year working in PIC assembler and C on a Palm PDA. After Oracle I moved to the other end of things in an IT sense, and discovered FPGAs and VHDL programming. Oh my, that's a brain-bender coming from computer programming. Anyhow, I am also interfacing FPGAs to a PC, and that's where C# comes in.
