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.

Get Logged In Users values from sql table

    Re: Get Logged In Users values from sql table

    I use an intermediary page between the Login and the Main menu in nearly every application. Most apps have a handful of such session variables. My biggest app has about 40 to start and may establish and hold additional items as the user progresses.

    Lee's right that sessions do expire and that can cause a problem.

    For those apps that require the equivalent of no session expiration, the main menu page (for simplicity's sake here) has some javascript on a timer that fires every 5 minutes. That javascript requests a 1 byte, 1px x 1px image from the server, effectively renewing the session every 5 minutes as long as the browser is open. Works very nicely, doesn't create a load problem.

    However, with the advent and growth of mobile/disconnected applications, more and more we're storing them not as session variables but as elements in the e object or for the lesser-used variables in localstorage (because it's slower).

    Richard - sorry to see you're having some problems. Here's a very simple sample snippet that may help:

    Code:
    . . .
    sql = "select ID, Firstname, Lastname from USERS where somefilterhere"
    cn.execute(sql, args)
    rs = cn.resultset
    session.Firstname = rs.data("Firstname")
    session.Lastname = rs.data("Lastname")
    . . .

      State variables are an excellent alternative to session variables. They are easily and readily accessible from both client and server side.

        Re: Get Logged In Users values from sql table

        I started using state variables and they seem to be working fine until one of my staff got a new computer. Then it seemed like a timing issues. As if the computer was too fast. If she used any other computer it worked, if she used her new one it said the variable wasn't there. I traced it with the debugger and there seems to be a moment when the state variable isn't accessible. I haven't had time to go back and really figure it out. I created a work-around for now...

          I use State variables and namespace variables almost exclusively now and haven't seen an issue. It'd be interesting to understand why your app is having trouble.

            Re: Get Logged In Users values from sql table

            When I get a chance... I can't get it it to fail in the IDE or debugger. It only fails on the new computer... I'm having other timing issues as well. Production is IIS with last Official Alpha release. My reports are called with arguments. Sometimes when my users press the preview button the first time they will get an error that there are no parameters. When they press the button the second time the preview works. That happens on all computers. I'm not sure if it is the update or going to IIS that caused this, but that is when it started. I didn't change any code in that area.

              Re: Get Logged In Users values from sql table

              Lee - you might, as a matter of general practice, put a small delay on those function calls that are depending on a previous one. Adding a setTimeout() for just 50 ms doesn't make any difference to the user but can make all the difference to a dependency.

                Re: Get Logged In Users values from sql table

                Thanks Steve. I was thinking about doing something like that. I just don't why it has been working for years without issue and after I moved to IIS it started doing it. I'm still learning the nuances of IIS.

                  I think the issues you're describing aren't server-side, but client-side which is why my suggestion focused on the javascript. Someone's got a new computer and it processing the javascript faster than your other users. Voila, trouble.

                  I seem to recall (do *not* bet on this) that a while ago Alpha announced they were wrapping all or nearly all javascript functions with a short timeout -- maybe just 10 ms. And this makes a lot of sense, even if my recollection is wrong.
