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.

  • No Brainer (Me or the Question?)

    Should be simple enough.

    On a form I have 2 calculators to help the user determine discounts & markups.

    Works sometimes when adding a record but not always or when changing.

    Re-Calc button calls for a "REFRESH" (Action Script). Help indicates this DOES NOT work in change or edit mode. Unfortunately the help fails to say what will work!

    Simply, the re-calc button should force the form calculated fields to re-calc & display.

    I never cease to be amazed at how the simpleset things screw up the works.

    Thanks , John

    Hi John,
    Help indicates this DOES NOT work in change or edit mode.
    To place in "view" mode use a topparent.commit(). You could even check the mode first to eliminate the overhead of committing when not necessary.

    Something like:

    Code:
    if tbl.mode_get()= 1 .OR. tbl.mode_get()= 2 then      'in change or enter mode
       topparent.commit()  'places in view mode
    end if

      What do the field objects shown on your form represent? A mixture of table fields and variables? What are the calculations done? Are they tied to events such as ondepart for the fields?

        Calculator 1:

        Standard Cost: Calculated (Field Rules) Reg. Cost - Disc %) .
        Trial Markup: Variable - user enter
        Trial List: Form calculated field: Std. Cost x Trial Markup.
        Margin: Form calculated field: Trail List - Std. Cost.

        Example:

        Std. Cost: 50.00
        Enter Trial Markup: 1.5
        Trial List: 75.00
        Margin: 25.00

        The idea is that the user may repetitively try different "Trial Markups" (Calc 1)
        or different Trial Discounts (Calc 2) until satisfied with the numbers.
        Calc 2 the same but different.

        Not tied to any events (what, you think I know what I'm doing?)

        Thanks, John

          John,

          You might try using variables only on the form, with the button's OnPush event with the code. Then a save button to write the vars to a table (if that is what you want) when the user has the results they are looking for.

            Sounds like a lot of work. Stan's question about on depart twigs the question, is there a command that could be placed in the on depart event , that would simply force the calc fields to re-calc.

            Sorry to seem so dense (always use A5 defaults & action scripting)

            Contrary to popular opinion, Laziness not necessity is the mother of invention.
            My story & I'm sticking to it.

            Thanks, John

              If memory serves, form level calculated fields should recalculate when any of the values involved in their expression definintion change. The only time you should need a commit and a refresh or resynch is if you are changing table level fields form representation. IOW, changing the value in a form object without saving the record does not change the table field value and thus calculations based on them do not re-calc.
              There can be only one.

                Getting closer. By your definition the form calculated fields will not re-calculate when an "ENTER Trial Markup" is inputted, because it is a variable.

                Would putting the "correct" command (refresh, resync....?) in the on depart event of this field force a re-calc.

                Thanks, John

                  A refresh() or resynch() command will not force a calc update as far as I know. Those commands update underlying data tied to a form.

                  But try the following in your OnDepart event:
                  Code:
                  tbl = table.current()
                  
                  tbl.recalc_calcFields()

                    I tried to recreate the first scenario and my form displays the trial list and trial margin changes immediately upon exiting the trial markup variable field. I did make my expressions for the form calculated fields a bit different.

                    Standard_Cost: Calculated (Field Rules) Reg. Cost - Disc %) .
                    Trial_Markup: Variable - user enter
                    Trial List: Form calculated field: Standard_Cost x var->Trial_Markup.
                    Margin: Form calculated field: calc->Trial List - Standard_Cost
                    There can be only one.

                      Worked but takes 10 seconds to calc. Seems ridiculous as there are only 20 form calc field in total (3 of which are lookups).

                      Sounds like we are on the right track.

                      Will try to fiqure out how to place only the required calc's in the on depart event.

                      Thanks, John

                        tbl.recalc_calcFields() recalculates the table level calculated fields for every record in the table.

                            By moving only the required calcs to the on depart event,

                            WORKS, Instantly:D.

                            Thank you all.

                            Aside

                            A5 is again creating duplicate form calc fields, some the same, some different.

                            Deleting them does not work. They just pop up again.

                            ????????

                            Thanks mucho, John
