Static Meter

[Jael]

I would like to create a circular meter (like a clock face) in a form that
has 50 "stops" or defined increments in 180 degrees (3.6 degrees per
measurement) The raw/plotted value would be between 40 and 90. I'd like an
indicator (line & arrow) to point to 9:00 (270 degrees) for 40, 12:00 (360
degrees) for 65 and 3:00 (180 degrees) for 90. I need the left side of the
circle background to be green and the right side to be red.
I can do this with a progress bar type meter but my client wants a circular
meter ("speedometer").
I'm using MSAccess 2003.

Any thoughts will be appreciated.
Thanks,
Jeff

I may have posted this twice, if so I appologize.
I need to display a circular meter (like a clockface) that has 50 points in
a180 degree section (1/2 circle). The data are 40 to 90 in unit increments
(3.6 degrees per point). For a value of 40 I want the pointer (line/arrow)
to point to 9:00 (270 degrees, the value of 65 to point to 12:00 (0 degrees)
and the value of 90 to point to 3:00 (90 derees) and be controlled to 3.6
degree increments. It's a static display that can change each time the form
is opened, but does not change as long as the form is open. Also I want the
left side background to be green and the right side background to be red.
I can do this with a modification of a progress bar, but my client wants a

circular meter ("speedometer").

I can also do it with 40 different images of the meter but there must be a
more "elegant" way.

I'm using MS VB 2003.

Any thoughts, links or suggestions would be appreciated.

Thanks,
Jeff

You may be able to find an ActiveX control that can do this, or you'll
be spending a fair amount of time writing your own.
If client understands the trade-offs, they may want to settle for the
progress bar.

You need a series of images, one for each position you want to display. The
in the Current Event of the form, display the verision of the image that
meets the requirements.

Thanks Dave. that's not the answer I was hoping for but....

I may try and program a meter using an image as a background and adjust a
line from the origin to the value using Sine, Cosine & line slant. I know
the angle needs to be in radians and the length, height in TWIPs. It might
be a fun challenge.

Thanks again and sorry for the multiple posts - never ran into that much of
a delay between posting and actually seeing them at my end.

I'll give it a try - its strickly a cosmetic thing with him. thanks. Jeff
