ACCESS FEED: Re: [MS_AccessPros] Unit Circle video uses Access to do the drawing

hi Dave,

thank you! Great comments! I had no idea about the rainbow, obviously.
You're right, I didn't mention changing the scale on the grid and did it
a few times. Sometimes I mention and don't explain, which might seem odd
compared to painstaking detail elsewhere. Circle area - didn't want to
leave it out, but also didn't want to get into integrals and
differentiating. An elementary or review mode would be nice. If you want
to look at something specific, there is a detailed index to jump to any
spot in the unit circle video here:

http://www.msaccessgurus.com/Teach/UnitCircle-VideoIndex.htm

I'll be posting code for drawing, probably within a week, here

https://msaccessgurus.com/code.htm

just want to clean it up a bit first though, and have more consistency
for parameter order from one procedure to another. As I drew more, the
code got better.

Each complex object like the sunshine, clouds, and stickman, can be
placed anywhere, and and its size can change. Only the face, however,
can be rotated. Now I'd like to rotate any of them, which means a few
helper functions, and changing the way they're done.

The video was made by recording the screen while flipping pages of
Access reports.

Each report is just one page in design. There are no graphic objects or
image controls. Code is behind the report and in helper functions. A few
different reports were used to keep the code from getting too long, and
make the logic easier when the scale was changed.

Each report record source is a table with sequential numbers in a field
called Num. For better page control, the Num control is in a group
section, instead of putting it in the detail, but it could have gone
there. On the property sheet, a page break is defined for the section
with Num. This way, code can test for page number and show or not show,
or turn on or turn off, what pages do or don't need. VBA keeps track of
the page number and runs the Page event each time the report goes to
another page.

Access seems to keep what each page looks like in memory. If you change
code while looking at the report, pages you haven't drawn yet will
change, but pages you've already rendered (looked at) won't. To see them
again, you have to open the report again. I usually switched between
Design View and Print Preview

I'll be making video tutorials about drawing with Access, and may give a
presentation on it too.

Your comments are super helpful! On pattern for Pi -- that's a whole
topic in itself!

thanks again,
crystal
