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.

  • Detect screen resolution

    Is there a way for the App Server to detect the screen resolution for the person that is viewing a web app?

    I'd like to define the size of certain elements, such as a text area, so it almost fills the screen. I'd also like to have a popup appear in the middle is the screen.

    If I could retrieve the resolution, I could place these elements accordingly.

    Javascript references to screen resolution are:

    screen.width
    screen.height

      David, thanks for the reply.

      Now, how do I capture those values with Alpha? Setting a variable to equal screen.width doesn't work - it returns a blank value.

        Bill also think about using "em" as measurements. They automatically adjust based on resolution. Here is a page with information: http://www.informit.com/articles/article.aspx?p=397663

          Re: Detect screen resolution

          Steve, thanks for the suggestion, but I'm already using % to size many elements. I need the screen width for those elements that are not amenable to using %, such as a text area, or the size of a pop-up window.

            Detect screen resolution - Solved!

            Well, it took about a week to figure it out, but thanks to Dave Jampole for pointing me in the right direction, I got it.

            The basic concept is that I have Javascript in my Login page that detects the screen width (it can get the height, too, but I don't need that). The script then opens one of multiple similar pages (call the RES pages for now) depending on the value of the width.

            Each RES page has Xbasic script that sets a session variable to the value of the width (i.e., the page called 1024.a5w sets the value to 1024).

            Then, the RES page uses response.redirect to open the main page. I use the value of the session variable to modify images, widths of elements (such as text area) that do not have the ability to use percentages in their sizing, etc.

            If you're interested in the details, email me at [email protected].
