1964, IBM 1620, 20K bytes memory, assembly and Fortran II (I'm 80). :-)

I took a programming class at Cal Poly when they got their 1st computer (1964-an IBM 1620 w/20K BCD bytes memory), and I got hooked (there was no way I was going to make a living as a Math major). Fortran II and assembly (I still have the instruction set manual-it was small). If you put a handheld radio up next to the console and ran a particular program, it would play 'Flight of the Bumble Bee'. :-)

I am trying to change the tab stops on the printer before I send formatted text (w/Tabs) to it. I can change the tab stops in stringFormat and use it when calling DrawString but they are completely ignored, e.g.,

Dim string\_format As New StringFormat
Dim tabs As Single() = {20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20}
string\_format.SetTabStops(0.0F, tabs)

e.Graphics.DrawString(txt, m_Fonts(para.FontNumber), _
Brushes.Black, layout_rect, string_format)

Anybody got any ideas? One would 'think' that this should be pretty straight-forward.
