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.

  • Round hours to 15 minutes

    I know I've seen this someplace, but can't find it.

    I'm working with time and want to convert hours to round to the nearest 15 minutes

    8.05 hours -> 8.00 hours
    8.20 hours -> 8.25 hours
    8.40 Hours -> 8.50 hours
    8.80 hours -> 8.75 hours

    Thanks ~ Tom

    I remember it too, will research.

    This seems pertinent to get you started.

      This is even more complicated than I thought.

      Hours is N,5,2
      So I need to separate the integer from the decimal.
      Then see if the decimal is between .125 below or above .25 to determine if it should round to .25 (quarter hour).
      I got .125 by dividing 7.5 minutes / 60.
      Am I on the right track?

        I have to disagree with you. You're not dealing with time that I can see. Purely numeric calculation.

        Search the desktop area for Numeric Rounding for a helpful thread. August of 2009 is the one I found.
        There can be only one.

          = 8
          = 8.25
          = 8.5
          = 8.75

            Hi Gab,

            I don't have a function called "Round_Fraction".
            I do have a "round_up" but it rounds up to the next integer.

            Round_up(8.10,.25) = 9.00 It should be 8.25

            Where can I find the Round_Fraction function?

              Hi Tom,

              Try this xbasic code as an example:

              dim ttime as c

              dim tleft as c

              dim tright as c

              if val(tright)>=0 .and. val(tright)<=14
              else if val(tright)>=15 .and. val(tright)<=29
              else if val(tright)>=30 .and. val(tright)<=44
              else if val(tright)>=45
              end if

                I posted this function and other modifications thereof long time ago in response to a related thread.
                This function allows you to round to any fraction.
                Here is the function:
                FUNCTION round_fraction AS N (base AS N, rounding_fraction AS N )
                	if dif>=mid
                	end if	
                END FUNCTION

                  This was in the thread I referenced, haven't tested extensively.

                    Thank You Gabe. And thank you all who gave this some thought.

                      Stan - Your solution looks even simpler. And of course, it WORKS!! I'll play with the two of them.

                      Thank You Very Much.

                        I'm taking no credit or blame. Just remembered there was such a thread.

                        Glad you have choices.

                          I do remember that expression as well. It might have been Steve Andrews's. At any rate, I also do remember modifying it into a function in order to accept any fraction, not just a quarter.
                          Here is the function:
                          FUNCTION round_frctn AS N (base AS N, fraction AS N )
                          END FUNCTION

                            Not to be a killjoy but if this is related to payroll time you might want to check with your state as to where the cutoff is for what fraction constitutes rounding up or down. Here in CA it is .08 hours goes to .25

                              Can you expound on this please? I have been doing payroll for years in California and have never heard nor found reference to this rounding rule. After reading your comment, I dug some more into it and still can find nothing.
                              What I did find was a CA Supreme Court ruling saying that federal law should be applied, and that rounding punch-in and -out times was acceptable. Referencing 08, the mention was that a punch out time of 5:08 was to be rounded to 5:15 in a quarter-hour rounding basis.
