Also, Dutchman and I have worked on closer integration of iConvert 3.4.sb and Update Currencies V2.sb
IMPORTANT: Download BOTH programs to the same directory. RUN Update Currencies FIRST.
That is only required at the beginning. After that, the two programs can be run in either order.
New UPDATE button in iConvert V 3.4 (See screen shot below)
Pressing this button deletes old data files and RUNS Update Currencies.
UC downloads new exchange rates, creates new data files and restarts iConvert 3.4
Here is the code for iConvert V3.4.sb
Code: Select all
/*
iConvert V3.4.sb
by rbytes and Dutchman, October 2018
Converts measurements in many categories.
A collaborative international project.
********************** NOTE *************************
The file "Update Currencies.sb" located at
https://kibernetik.pro/forum/viewtopic.php?f=20&t=2272
must first be run before iConvert can run, since
iConvert requires a "currencies.data" file in the
same path as an include file!
******************************************************
V3.4
- Acceleration category added by rbytes
- Update button added to launch "Update Currencies V2.sb"
for updating currency exchange rates
V3.3
- Flow Rate category added by rbytes
V3.2
- Angle category added by rbytes
- Energy transition category added by Dutchman
- Error trap added for Currency
V3.1
- Temperature category added by Dutchman
V3
- Currency category added by Dutchman
DATA generated with "Update currencies.sb"
V2
- animation added to title
(plays only once, at launch)
- measures added in most categories
- scientific notation is now used for
results larger than 100,000,000 or
smaller than .00000001
V1.1
- added Horsepower (Metric) to
Power category
- eliminated >>> button;
calculation is now automatic
when list selections or
input values are changed.
- code efficiency improved

• Be sure that the constant "Convert$" in "Update currencies" (on red background) has the correct name of "iConvert"
• Delete the files "currencies.data" and "currencies.html <date>"

Here is the code for Update Currencies V2.sb
Code: Select all
'Update currencies V2
'by Dutchman, october 2018
'Generate DATA-list for currency-conversion
'
/* V2
20181103 Adapted with 'View' options
• Test-mode is changed to View-mode. If View is non-zero then program is interactive.
Default: View=0
• If "currencies.data" is not present, then View becomes inactive if "currencies.html <date>" is present. The program will then extract data from that html-file and generate "currencies.data".
This is the test-mode for data-extraction.
• If both files, "currencies.data" and "currencies.html <date>", are not present then View becomes active and the conversion-program identified by 'Convert$' will be started after finishing.

So I tried UC in landscape as a test and it worked perfectly with no code changes. iConvert would need major redesign to switch it to portrait orientation.
