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.

  • Text Formatting in Freeform Grid

    Hi,

    I am passing a session variable from a grid to another grid. The session variable is created in the original grid. I have a freeform text field in the target grid and have entered the following code;

    Code:
    <%a5 session.vInt_Desc = lookup("[PathAlias.ADB_path]\tbl_obj_int_link","Link_id="+quote(session.link_ID),"Int_desc")
    ? session.vInt_Desc %>
    The text in the original grid field is formatted with carriage returns, but when i display the target grid using the code above, all the formatting is ignored and you get one string of text.

    Does anyone know a way i could maintain the formatting in the target freeform grid field?

    Thanks,

    Denis

    Denis,

    You need to tell the browser how to handle it. Browsers don't know about carriage returns/line feeds (crlf). I use something that Alpha examples use.

    Place this function ate the end of your page (after an END statement):

    Code:
    function jsEscape as c (txt as c)
        jsEscape = stritran(txt,"'","\'")
        jsEscape = stritran(jsEscape,crlf(),"\n")
    end function
    The call that function within your print (?) command:

    Code:
    ? jsEscape(session.vInt_Desc)
    I also recommend using "s_quote" over "quote" because you can use it across data types (i.e., it will quote text as text, date as date, etc.)

      Stephen,

      Thank you for responding.

      Does this code need to go onto the .a5w page or grid component page. Can you be specific on exactly where in the page this should go please.

      Code:
      function jsEscape as c (txt as c)
          jsEscape = stritran(txt,"'","\'")
          jsEscape = stritran(jsEscape,crlf(),"\n")
      end function
      Should my calling code look like this?

      Code:
      <%a5 session.vInt_Desc = lookup("[PathAlias.ADB_path]\tbl_obj_int_link","Link_id="+quote(session.link_ID),"Int_desc")
      ? jsEscape(session.vInt_Desc) %>
      One step forward, i feel we are getting close to achieving this.

      Thanks,

      Denis

        Or add HTML to your original text. To make paragraphs line break, you can either add <br><br> to the end of each paragraph, or bound each paragraph with <p>...</p>.

          The text is created within a grid memo field. How would I use the html tags to view the unknown text.with the correct formatting.

          Thanks for replying, by the way.

            You would alter the text right in the memo field, adding <p>...</p> around each paragraph, or adding "<br>" to the end of any paragraph. You can manually enter this in the memo field or search this forum for HTML Editor and use that freeware from my website. Just like on this forum, we type our messages in an HTML Editor so the text has proper HTML.

            Or you can use what Stephen proposed (with slight modification) to handle just paragraph returns. The modification you need is to replace the "\n" in the script with "<br>". The "\n" will just add "\n" to your text.

            Or you can do it this way since you only care about returns:

            txt = lookup("[PathAlias.ADB_Path]\mytable",".t.","myMemo")
            txt = stritran(txt,crlf(),"<br>")
            ?txt

                Steve,

                Your code;

                Code:
                txt = lookup("[PathAlias.ADB_Path]\mytable",".t.","myMemo")
                txt = stritran(txt,crlf(),"<br>")
                ?txt
                Absolutely, brilliant.

                  Credit should go to Stephen. I just tweaked what he suggested.
