put vb in its MDI interface
Tools-Options-Advanced
if Option 'SDI Development Environment' is checked then uncheck it and the next time vb starts it will use its

MDI Development Environment

when vb is in its MDI mode:
it will show an MDI-form with in it a normal form (Form1)
chance Form1's borderstyle to 1-Fixed Single
change it's height to 100000
immediately the (vb's) MDI-form will show a scrollbar
you can now scroll Form1 up-down over the entire 100000 twips
and you can place controls anywhere over its entire surface
if you now run the program, you will not be able to see its entire surface
thats normal because Form1 is not an MDI-child
make Form1 an MDI-child
if you now run the program vb will complain that there is no MDI-form
add a MDI-Form
run the program
thats it
