Moons of Jupiter

[Stellaferox]

Hi Mike,

I can give you an exact answer on the question when Jupiter will be back if I can consult my starcharts tomorrownight but meanwhile you can download an earlier program of mine which is called Planetarium and let it run in forward mode. When the angle between Earth and Jupiter becomes less then 100-120 degs appr. the date tells you from when it will be visible in the east early before sunrise. It also tells you that Saturn and Mars are nice objects right now!

grtz,

Marc

Jupiter becomes a morning object in early march, will be rising by midnight in June and by September is rising at sun set. Mars is around at the moment though and in a small (ish) telescope you should be able to see some features with high magnifications on nights of steady seeing :-)

Have a look at CMHAS - home

I suddenly took it into my head to make a version for VGA size on my desktop (or for that matter, larger). But it fails, running under IDE, at the first frmMain.FPolygon(), saying "Object reference not set...". This is the case for the downloaded version too (see attachment).

Rather than bash my head against this puzzle (possibly due to using V6.90) I thought I would eliminate the ArrayLists, which aren't really needed because there are always 37 elements, and use structures instead. This should be more efficient, though I don't expect to see the difference. It did cure the problem, though!

Hi Stellaferox,

Ever since I changed to Android I haven't touched B4PPC.
A few years ago, I wrote a pretty complete application that
simulates the motions of the Jovian moons. See attached manual.
The free software is now discontinued.
If that is something you'd like to further develop, then please
send me a PM.

Please appreciate that the code is not documented and that I
am unable to provide any kind of support. You will be entirely
on your own.


Don't know whether you are also developping for Android phones.

A free widget that simulates the Jovian moons:

A paid, but fully featured application:

Both based on my work for the Pocket PC.

Cheers
Robert

1) Search does not work for only three-letter search terms. (But the response does not tell you this; lousy interface!)

2) An sbp file is source code for Basic4PPC, which is what this forum is for:

Android Development Forum - Basic4android > Basic4ppc > Share Your Creations > Moons of Jupiter

It is unfortunate that it is so easy to confuse these two quite separate products. (Buy one and you do not get the other!)
