Bonus TIPS for Successful Posting

Try a Search First
It is highly recommended that a Search be done on your topic before posting, as many questions have been answered in prior posts. As with any search engine, the shorter the search term, the more "hits" will be returned, but the more specific the search term is, the greater the relevance of those "hits". Searching for "table" might well return every message on the board while "tablesum" would greatly restrict the number of messages returned.

When you do post
First, make sure you are posting your question in the correct forum. For example, if you post an issue regarding Desktop applications on the Mobile & Browser Applications board , not only will your question not be seen by the appropriate audience, it may also be removed or relocated.

The more detail you provide about your problem or question, the more likely someone is to understand your request and be able to help. A sample database with a minimum of records (and its support files, zipped together) will make it much easier to diagnose issues with your application. Screen shots of error messages are especially helpful.

When explaining how to reproduce your problem, please be as detailed as possible. Describe every step, click-by-click and keypress-by-keypress. Otherwise when others try to duplicate your problem, they may do something slightly different and end up with different results.

A note about attachments
You may only attach one file to each message. Attachment file size is limited to 2MB. If you need to include several files, you may do so by zipping them into a single archive.

If you forgot to attach your files to your post, please do NOT create a new thread. Instead, reply to your original message and attach the file there.

When attaching screen shots, it is best to attach an image file (.BMP, .JPG, .GIF, .PNG, etc.) or a zip file of several images, as opposed to a Word document containing the screen shots. Because Word documents are prone to viruses, many message board users will not open your Word file, therefore limiting their ability to help you.

Similarly, if you are uploading a zipped archive, you should simply create a .ZIP file and not a self-extracting .EXE as many users will not run your EXE file.

  • Wind Direction Xbasic

    Don't laugh at my code if you can easily see how it could be more efficiently written!
    I did my best.

    So here's the scenario. I am using an API to pull in the weather data, specifically the wind direction and speed. The wind direction comes back from them as the degrees of a circle, so 360 is the same as zero which would be North (N) as well as the first 11.25 degrees, 180 would be due south, 45 degrees NE, and 90 degrees E. I wanted to use the appropriate abbreviation based on the degree so I did some research and I think I got it!
    It took me all evening as I have never used an array, and not real familiar with math functions.

    I took some javascript i found and figured out how to make it work in xbasic...
    Again, what this does is display the right abbreviation based on the returned json data in the api call to
    I thought I might share...and if you do see a way to make it better let me know - it was my first stab at this!
    The variable "purl" is a concatenated field to include the required URL with the lat & lon fields and my appid as required by the API

    function weathercall as c (e as p)
        dim weathercall as c
    dim myresponse as p
    dim purl as c
    purl = e._currentRowDataNew.concat_coordinates
    myresponse = http_get(purl)
    dim pp as p
    pp = json_parse(myresponse.body,.t.)
    e.control.wind_speed = pp.wind.speed
    e.control.deg = pp.wind.deg
    dim num as n
    dim val as n
    dim mydir as c
    dim mydir2 as c
    dim numoff as n
    num = pp.wind.deg
    numoff = (num - 11.25)/22.5
        val= round(numoff,0)
        mydir = abs(val)
    dim arr[16] as p
    mydir2 = arr.dump_properties(mydir)
    e.control.wind_direction = mydir2
    end function

    Very nice result. Well done.

      Hi Paul,

      Any time you get things working the way you want, you've done a good job.
      With that said, you could just dim arr as p. No need for the [16].

            I know it's always easier when someone else leads the way, but here's my little xbasic function.
            Then 2nd box of code works (tested) with a mysql select statement.

            function dirtext as C (heading as N)
            dirtext = case( heading < 12,"N",heading < 34,"NNE",heading < 57,"NE",heading<79,"ENE",heading<102,"E",heading<124,"ESE",heading<147,"SE",heading<169,"SSE",heading<192,"S",heading<214,"SSW",heading<237,"SW",heading<237,"SW",heading<259,"WSW",heading<282,"W",heading<304,"WNW",heading<327,"NW",heading<349,"NNW",heading>=349,"N")
            end function'dirtext
            when fl.heading = 0 then 'STOPPED' when fl.heading < 12 then 'N' when fl.heading < 34 then 'NNE'
            when fl.heading < 57 then 'NE' when fl.heading < 79 then 'ENE' when fl.heading < 102 then 'E'
            when fl.heading < 124 then 'ESE' when fl.heading < 147 then 'SE' when fl.heading < 169 then 'SSE'
            when fl.heading < 192 then 'S' when fl.heading < 214 then 'SSW' when fl.heading < 237 then 'SW'
            when fl.heading < 259 then 'WSW' when fl.heading < 282 then 'W' when fl.heading < 304 then 'WNW'
            when fl.heading < 327 then 'NW' when fl.heading < 349 then 'NNW' when fl.heading >=349 then 'N'
            end )

              Have not tested this, but if you are really interested in speed, then tyy
              dim dir_list as C = "N,NNE,NE,ENE,E, ..."
              dim degs as N = return value
              dir_num = int(degs/15)
              dir_display = word(dir_list,dir_num,",").

                I tested this and have some modifications First, since the direction is only for display, add another N on the end. of the list of directions. You don't need an array.
                dim dir_list as C = "N,NNE,NE,ENE,E,ESE,SE,SSE,S,SSW,SW,WSW,W,WNW,NW,NNW,N"

                then add your 11.25 degrees to the number of degrees returned to rotate the left side of north to the top of the circle
                dim degs as N = return value + 11.25

                since word is 1 based, add 1 to the dir num
                dir_num = 1 + int(degs/22.5)

                One of the Alpha guys told me that the word function is a very fast function unlike the case function that looks at every option,
                dir_display = word(dir_list,dir_num,",").

                  I wonder how much faster it is ?
                  In the example shown I use 355 to ensure it would have to check each possibility.
                  As a sidenote, the 22.5 comes from dividing 360 by 16.

                  function dirtext as P (heading as N)
                  dirtext.beg = now()
                  dirtext.begd = time("yyyy-MM-dd 0h:0m:0s.3",dirtext.beg)
                  ' debug(1)
                  dirtext.result = case( heading < 12,"N",heading < 34,"NNE",heading < 57,"NE",heading<79,"ENE",heading<102,"E",heading<124,"ESE",heading<147,"SE",heading<169,"SSE",heading<192,"S",heading<214,"SSW",heading<237,"SW",heading<237,"SW",heading<259,"WSW",heading<282,"W",heading<304,"WNW",heading<327,"NW",heading<349,"NNW",heading>=349,"N")
                  dirtext.fin = now()
                  dirtext.find = time("yyyy-MM-dd 0h:0m:0s.3",dirtext.fin)
                  dirtext.elapsed = dirtext.fin-dirtext.beg
                  end function'dirtext
                  = beg = 04/30/2022 09:05:26 35 am
                  begd = "2022-04-30 09:05:26.354"
                  elapsed = 0
                  fin = 04/30/2022 09:05:26 35 am
                  find = "2022-04-30 09:05:26.354"
                  result = "N"

                    Thanks for that excellent demonstration. Yes, the difference is very small in this case (no pun intended) so it really doesn't matter which way you do it. Charles' question was can it be "more efficiently written" which I took to mean amount of code to write and speed of the calculation. I can see that I might have offended those who suggested the case statement, but that was not intended. I meant to show that the word function is a good technique that often doesn't come to mind in cases like these.

                      I don't take offense at anything you say.
                      I chipped in with this because I just put it into play at the office.
                      Samsara sends the heading, but not the text display. I chose to let mySQL do the conversion.

                        over all its a great debate - It is always interesting to see the many different ways code can be written to achieve a desired result. Thanks!
