Modifications (14.01)

P00. Fixed crashing issue with Version 14.00p104. New compiler caused issue New compiler now supports Windows 7.
P02. Added support for La Crosse Technology WS-2810, as well as other newer La Crosse weather stations where the currdat.lst file is located in a different location than the Heavy Weather Executable file. For the WS-2810, I recommend deleting the file \vws\setup\config6.bin (which stores the Communication | Communication panel information) and restarting Virtual Weather Station software. Next, select the WS-2xxx series weather station as the weather station type.
P03. Crashing issue was back. Found it to be the 5-Day Forecast panel. Not sure why but reduced the number of five day forecast selections from 3 to 1. Not sure if this is a windows issue or a compiler issue, because the actual code is not crashing. I apologize to those that use more than one forecast location.
P04. Added jpeg file error notifications in status bar. One user can not determine why he an not generate jpeg files.
P05-P06. Bracketed bad dates better by only allowing downloads within 2 years of current computer or system date. Added more messages to determine why WMR200A archive downloads are sometimes incomplete, including bad data strings and CRC errors. This information is written to the file \vws\date\wmr200archive.txt.
P07. cvinet.dll was missing in 14.01.
P08. Crashing continues. Still appears to be related to 5 Day Forecast panel. The debugger does not give any clues so I can only point the finger at the compiler + development platform I use from National Instruments. I deleted this panel and built in from scratch, changing some of the presentation of the data. You will have to set this panel up again, which involves setting the timer, and entering your location. Sorry folks, this has been a real pain to solve.
P10. In the latest version of Heavy Weather, they changed their executable filename and location. It used to always be located here: c:\program files\HeavyWeather\Heavy Weather.exe, so all the user had to do was browse to the directory. Now I have the user find the actual file instead of the directory. If you need to correct this, Under Communication | Communication, rebrowse to the HeavyWeather file location. There is more information here: http://ambientweather.wikispaces.com/HeavyWeather+Default+File+Locations

P11. Fixed issues with daily, monthly and yearly rain. Prevented 0.00 total rain value having effect on calculating the daily, monthly and yearly rainfall (some weather stations do not calculate these values so VWS must calculate them. However, some stations have issues with zero "spiking" to zero and causing the daily, monthly and yearly rainfall to reset to the total rainfall. VWS now throws out any zero rain value. I used to debouce it 5 cycles but that did not always work. Also changed the Settings | Rainfall panel to make it easier to edit daily, monthly and yearly values.
P13. Updated database from 20,000 points to 50,000 points.
P14. There was a bug in Version p13 that would give you an error message that the database was exceeded.
P15. A couple of users are experiencing high and low summary read and write errors. I added code that creates a file called \vws\data\summary.txt to see what types of errors these are. You can send this file to me: ed@ambientweather.com if you have issues. Also, the summary files were only written once per day and at shutdown, and if you did not gracefully shut VWS down, you would lose this data. I now write this data once per minute.
P18. Did not properly handle the day change highs and lows in Version 14.01p16. Fixed. Some users have complained of ghosting issues when program is undiminished. Fixed by maximizing, minimizing and maximizing again. Yikes, Windows can be flaky.
P19. Implemented new Davis DLL which fixes minor issues documented here: http://davisnet.com/support/weather/software_dllsdk.asp
P20. Issues with resizing database resolved. No longer get annoying popup at start up if database needs resizing.
P21. Some users still complaining about missing downloads. I have never been able to reproduce but I changed the keep alive write command. It would only send it out if data was read first. Now it sends it out regardless if any data was read back. I can not guarantee this will fix it, just trying different things out because I can not reproduce.
P22. When the latest Davis DLL was implemented, it would default the display console to imperial units. I fixed this by getting the units first and then setting the same units in the get units command.
P23-24. Found and fixed issue with plotting THWS parameters.
P24-25. Added error tracing for daysum.txt file from the summary.txt file. One user is having issues with this file. Added Keep Alive Flag option for the WMR200. One user is having issues with no or interrupted downloads. I added this feature to troubleshoot. If downloads are intermittent, turn on or off this flag. Select Communication | Sensor Communication | Keep Alive Flag to set this flag.
P26. Fixed issue with program crashing if more than 91 file parameters are selected for file reporting.
P27. Fixed issue with database. Could not edit beyond 30,000 records.
P28. If a warning is set and clears, the message "No Warnings" on the webpage will not be displayed.
P30. Added WMR88A to list of weather stations. This is a new Oregon Scientific weather station.
Also fixed crashing and display issues with Distribution Graphs for higher numbered parameters.
P31. Version p30 broke Wind Direction distribution. Fixed.
P32. Asked for Disk 2, would not install.
P32. Addressed issues with daily, monthly and yearly highs and lows that feed the displays and NOAA reports. The data would get corrupted. The new version will only allow a high and low to be entered if the current date and time exceeds the high and low date and time. This has something to do with the timing of the program with relation to the timing of the weather station clock, as well as bogus data. This can also effect the daily, monthly and yearly rainfall. Fixed issue with 5 day forecast. You must set up this panel again. Also fixed Davis Instruments forecast issue - if it is below 32 deg F, the icon will show snow instead of rain.
P33. Fixed issues introduced in p32. Insert Disk 2.
P34. Fixed issue related to highs and lows, Rainwise and introduction of p32.
P36. Continue to troubleshoot Rainwise and highs and lows.
P37. Fixed METAR reporting when temperature is missing from report. highs and lows seem to have trouble now, not sure if it is this update or wunderground upgrading there web site. Not sure if I like the change.
P41. Ongoing issues with Rainwise. Trying to resolve issues with highs and lows rolling over.
P42. Resolved database overflow issue. The database would get corrupted if 50,000 points was reached and resized.
P43. p42 did not completely resolve the issue.
P44. Fixed crashing issue with WeatherBug.
P46. Removed debug code for Peet Bros.
P48. When Wunderground.com weather warnings time out, it does not parse the data properly. I did a few things: (1) increased the timeout from 10 seconds to 60 seconds (2) If there is a download error, the tag will display an error in retrieving data instead of No Warning. (3) under some circumstances, the tag would not parse properly..
