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.

    Ajax Callback is failing

    The ajax callback below fails, I can only see it fail while debugging. The error returned is an sql error: NativeCode=242

    I believe it has to do with the datetime variables that are converted to a character type. If I try to dim them as T, I receive an error. It forces me to convert the datetime value to a character string for the script to even run. Can anyone tell me what I am missing? Thanks for any feedback!

    if eval_valid("Request.Variables.progress_id") then
    	dim progID as N=convert_type(Request.Variables.progress_id,"N")
    	dim actualenddate as C=convert_type(request.Variables.V.R1.AT_ActualEnd,"C")
    	dim actualstartdate as C=convert_type(request.Variables.V.R1.AT_ActualStart,"C")
    	dim ok2pay as N=convert_type(request.Variables.V.R1.AT_Ok2Pay,"N")
    	if progID>0 then
    		dim conn as SQL::Connection
    		dim args as SQL::Arguments
    		dim sql as c
    		sql = "UPDATE rems.njobslstasks SET actualstartdate = :asd, actualenddate = :aed, oktopay = :ok2pay WHERE PROGRESS_RECID_IDENT_ = :progid""::Name::MYDS")
    	end if
    	UpdateAllOpenTaskDetail="alert('Update Failed');"
    end if

    Re: Ajax Callback is failing

    You wrote 'args.set("ok2pay",ok2pay)' and 'oktopay = :ok2pay' .... shouldn't the last part be 'ok2pay = :ok2pay' ??

    You wrote "to" instead of "2" ... not sure if that is a problem or not.

      Re: Ajax Callback is failing

      That's the name of the variable and argument but the name of the field being updated is oktopay


        Re: Ajax Callback is failing

        The ajax callback runs now but here is the date value for that record 1900-01-01 00:00:00.000

        It should have been today's date. Has anyone else encountered this who can tell me how to prepare the datetime value so that the proper value gets submitted?


          Re: Ajax Callback is failing

          We don't know what the variables actualstartdate and actualenddate have as values, but assuming a character string something like "12/18/13" or "12/18/2013", this should work:


            Re: Ajax Callback is failing

            SQL databases love date formats as 2013-12-18. If you throw that at them they'll never squak. If you look at your data in the sql field and follow that format for date and time you'll be great.


              Re: Ajax Callback is failing

              Thank you for your feedback Chris and David. I've been plugging away at this and have tried a few different ways to reformat the date so that the SQL server will accept it but to no avail. I tried your solution Chris. Variables look like this 12/17/2013. The value that gets submitted to the database is still the result I posted above. Really irritating.


                Re: Ajax Callback is failing


                Part of the clue is in the date value for the record that you're seeing... you say it's 1900-01-01 00:00:00.000

                Apart from the time value (which doesn't matter in this case)... we're seeing that sql is formatting the date as yyyy-mm-dd. It's not obvious about the month part... but that's it.

                So... that's what you must give it.

                Have a look...
