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.

    Session Variables as Date values in Array? Access Session Variable from Javascript ?

    I spent the better part of the day yesterday searching the Forum and help files for answers and never really came across anything that resolved my problem.
    This should be such a simple thing, Maybe I'm just going about it all wrong.

    [useing V11 Application Server]
    What I need to do is read field values (dates - 30 of them) from one single indexed record in an External table.
    These values then become column Labels as well as input values for multiple records in the current grid / table.

    I thought I could Publish a Session Variable, then use it as an array to load the values into,
    and by using a Session Variable I could access those values in javascript to set the column labels.

    Can Session Variables be used as Arrays? If so, how?
    I have tried multiple different ways and always come up with errors.
    I also tried this : <array>.INITIALIZE_FROM_TABLE(tbl) and could not get it to work with Session variables (actually, I couldn't get it to work at all)
    If anyone has some sample code they could share for a "visual" that would be great.

    I read that with V11 Session Variables must be strings.
    The field values I need to read into Session Variables are Dates, and need to be stored as Dates.
    Can a Session Variable be used as a Date field?

    As stated above, I want to use these external values as Dynamic Column Labels.
    I'm familiar with the [window ] $('fullname').innerHTML= fullname; combined with <div id=.... > method to create dynamic column headers,
    But my problem is passing the variable to the javascript.

    I Published SESSION.WHATOFFICETERM in Grid Properties, then in onGridRender :

    var myvar={grid.Object}.getSessionVariable('WHATOFFICETERM');

    myvar returns "undefined" everytime, even if I set SESSION.WHATOFFICETERM = "test" in OnGridExecute (ie, just trying to force this to work)

    does anyone have any suggestions as to why the getSessionVariable may not be working?

    Thank you in advance,
    Kim

    Kim,
    Since you have the session variable and want them as column Labels after you publish the session variable in the grid properties then in the field label stick this <%A5 ?SESSION.WHATOFFICETERM%>.
    This might work for you let me know if there are any other variables I am unaware of or did not address.

      Thank you Colin!! Your suggestion for the label was a real time saver and much easier than my previous methods!

      I was able to take that a step further and break my "date" field down into mo-dd<br>year -- which displays very nicely.
      [since I'm using the date for the column header -- and have a record with 24 date fields, I'm using checkbox fields so the user can just "x" the box ]
      <%A5 ?substr(SESSION.MTG1,1,2)+"-"+substr(SESSION.MTG1,4,2) %><br><%A5 ?substr(SESSION.MTG1,7,4)%>

      The session variables were still a struggle; it appears (at least after my umpteen million attempts with different formats)
      that Session.variables can not be assigned as arrays. If anyone knows otherwise, and has demo code to share, great!

      I removed all array references.
      I was then initializing my session.variables in OnGridInitialize. Still, I could not get them to show up in any of my field references (Calc Grid Fields)
      I then moved all the session.variable assignments to OnGridExecute; STILL, no luck (I have used session variables before, and did not have this kind of trouble!)

      FINALLY I resolved my session.variable references with one simple change:

      Instead of assigning them with SESSION.VARNAME='var' as the examples in the event show,
      I used e.rv.session.varname = 'var' and walah !! everything worked perfectly.

        Kim,
        Glad it worked and that's interesting about the e.rv.session.varname, I have never used that.
        Let me know if you need anymore help!!
