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.

    How do I set a field as Null

    Hi, First question here so be gentle lol

    I have a button which concatenates 9 address fields on a form into a single field to make for easier data entry and copying addresses from emails. This is using Events>OnPush>Set Field Values in the Expression Builder of the Code Editor. I used the comma_to_crlf command to add line feeds in the final field:

    comma_to_crlf(
    Ship_Address_1 - ","
    + Ship_Address_2 - ","
    + Ship_Address_3 - ","
    + Ship_Address_4 - ","
    + Cust_Address_5 - ","
    + Ship_City - ","
    + Ship_State_Region - ","
    + Ship_Postal_Code - ","
    + Ship_Country )

    There are 2 things that need to be done before rolling out on the desktop application.

    1) How do I test fields in the code editor so that blank fields are ignored in the expression above, so avoiding multiple blank lines in the final address field;

    2) What is the command/syntax used to set the now redundant fields to a Null value.

    Thanks.

    Instead of what you have create a calculated field for the form

    addr_to_use = comma_to_crlf(
    if(alltrim(Ship_Address_1)>"",Ship_Address_1 - ",","")
    + if(alltrim(Ship_address_2>"",Ship_Address_2 - "," ,"")
    + if(alltrim(Ship_Address_3>"",Ship_Address_3 - ",","")
    + if(alltrim(Ship_address_4>"",Ship_Address_4 - "," ,"")
    + if(alltrim(Cust_Address_5>"",Cust_Address_5 - ",","")
    + if(alltrim(Ship_City>"",Ship_City - ",","")
    + if(alltrim(Ship_State_Region> "",Ship_State_Region - ",","")
    + if(alltrim(Ship_Postal_Code> "",Ship_Postal_Code - ",","")
    + if(alltrim(Ship_Country>"",Ship_Country,"") )

    Unclear what the now redundant fields might be.

      Hi Brian,
      Welcome to the board.

      Check out the remove_blank_lines() function.

        Hi Stan and thanks.

        Not sure what your functions do yet but will try tomorrow.. it almost packing up time here.

        The redundant fields are the fields that contained the individual address lines which have been copied to the combined address field, but still contain the individual data. I want these to be Null for the appearance of the form until they are removed completely.

        Cheers.

          Robin's suggestion is simpler.

          remove_blank_lines(comma_to_crlf(
          Ship_Address_1 - ","
          + Ship_Address_2 - ","
          + Ship_Address_3 - ","
          + Ship_Address_4 - ","
          + Cust_Address_5 - ","
          + Ship_City - ","
          + Ship_State_Region - ","
          + Ship_Postal_Code - ","
          + Ship_Country ))

          should do it.

          My suggestion is the way we did it in the old days before some of the bells and whistles were added.

            Couldn't wait so I tried Stan's, but that needs more tweeking as I am getting an "incomplete" error in the expression editor.

            Robin's worked like a charm. Thanks to you both.

            Now if I could only set the redundant (ie completed, but no longer needed) data fields to Null.

            I'm definitely leaving now :-)

            Cheers, Bri

              Was trying to cut and paste on screen instead of copying it to Alpha. Left out some right parens. Should be

              addr_to_use = comma_to_crlf(
              if(alltrim(Ship_Address_1)>"",Ship_Address_1 - ",","")
              + if(alltrim(Ship_address_2)>"",Ship_Address_2 - "," ,"")
              + if(alltrim(Ship_Address_3)>"",Ship_Address_3 - ",","")
              + if(alltrim(Ship_address_4)>"",Ship_Address_4 - "," ,"")
              + if(alltrim(Cust_Address_5)>"",Cust_Address_5 - ",","")
              + if(alltrim(Ship_City>)"",Ship_City - ",","")
              + if(alltrim(Ship_State_Region)> "",Ship_State_Region - ",","")
              + if(alltrim(Ship_Postal_Code)> "",Ship_Postal_Code - ",","")
              + if(alltrim(Ship_Country)>"",Ship_Country,"") )

                If you're speaking of blanking out the visible form fields, set the value property to "" after you've filled the composite field. If you want to blank all the individual address fields in the table, create an update operation that sets each to "".
