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.

  • Military to Standard Time

    I've spent wayyyyyyyyyyyyyyyy too much time on this.

    I need to convert military time to standard time as follows:

    1730 -> 5:30a

    My convoluted code that works in the expression builder, but not in the update operation is the following.

    IF(toseconds("1730")*3600>=43200,Left(Padl(Totime(toseconds(left("1730",2))*3600+(val(right("1730",2))*60),11,0),8,"0"),5)+"p",Left(Padl(Totime(toseconds(left("1730",2))*3600+(val(right("1730",2))*60),11,0),8,"0"),5)+"a")

    What am I doing wrong? Remember this is in A5V4.5

    Thanks

    Tom, does your military time always include 4 digits and no colon? i.e. 0230 for 2:30 am?

    I don't remember that A5v4 supports a "time" data type. So when you say "standard time", you're really talking only about a character data type field, right?

      Correct no colon and should be 4 characters, but I don't force it.


      Yes, the field is 6 characters wide. Hence the "a" or "p" to squeeze "12:30 pm" into 12:30p

      Thanks for taking a look.

        If you force military time to always have 4 digits you can do this, but I'm not sure it's any easier to maintain.

        Code:
        m_time = "1630"
        dim s_time as c
        s_time = if(val(left(m_time,2))< 12, left(m_time,2) + ":" + right(m_time,2) + "a", if(val(left(m_time,2)) = 12,  left(m_time,2) + ":" + right(m_time,2) + "p", ltrim(str(val(left(m_time,2)) - 12)) + ":" + right(m_time,2) + "p"))
        ?s_time
        = "4:30p"

          Tom,

          It doesn't work in the update operation. It leaves the minutes blank, but does add the "p" or "a"

          Code:
          dim s_time as c
          dim m_time as C
          m_time="1730"
          s_time = if(val(left(m_time,2))< 12, left(m_time,2) + ":" + right(m_time,2) + "a", if(val(left(m_time,2)) = 12, left(m_time,2) + ":" + right(m_time,2) + "p", ltrim(str(val(left(m_time,2)) - 12)) + ":" + right(m_time,2) + "p"))
          ?s_time
          = ""

          The above code in the expression builder works fine, but in the interactive window it results in ""

          ????

            If your field width for military time is more than 4, it's likely the

            right(m_time,2)

            is simply supplying blanks, since the trailing blanks are the last two chars stored in the field

            Trim your field width.

            My example assumes a width of 4, with all places filled.
