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.

    Here Is A Method To Fetch The Browser Type And Version ...

    I wanted to determine what browser the user is using because there can be problems with native mp4 video playback in browsers other than Internet Explorer.
    If I know what browser they are using, I can notify them that they cannot view the video if it's not IE. I still have this to sort out, but at least I can get the correct browser and version for now :)

    After researching this it turns out to be not as simple as it seems. However, I have found what I think to be a very simple solution and it seems to be working well.
    It uses a 3rd party javascript file called 'bowser.js' .. you can read about it here ... https://github.com/lancedikson/bowser
    I downloaded the entire package, but I think only the bowser.js file is needed for this. I've attached it here as well.

    Setup is simple:

    1. In the Web Projects Control Panel add the bowser.js file

    1. Javascript File.png

    2. In the UX Properties add bowser.js to the Javascript Linked Files

    2. Javascript Linked Files.png

    3. Call code to execute the javascript. In this test case I have the following code in the button OnClick event which puts the returned data into the control called Result.

    Code:
    {dialog.Object}.setValue('Result','Browser is '  + bowser.name + ' ' + bowser.version);

    Here is a video demonstrating the result: https://www.screencast.com/t/Rggr3ER9q
    The sample UX is also attached.

    Thanks for this - this is a very important thing to now as it allows us to avoid differences in browser issues we bump into from time-to-time. Well done.

          You can basically get all the browser information with simply:
          navigator.userAgent

          Code:
          alert('navigator.userAgent: '+navigator.userAgent);
          And in a5.js, they have helped with creating a bunch of flags concerning the userAgent.
          For instance:
          A5.flags.isMobile
          A5.flags.isWebKit
          A5.flags.isOpera
          A5.flags.isFireFox
          A5.flags.isIE
          A5.flags.isWindows
          A5.flags.isIPhone
          A5.flags.isIPad
          A5.flags.isXoom
          A5.flags.isKindle
          A5.flags.isPlaybook
          A5.flags.isGalaxy
          A5.flags.isTouchPad
          A5.flags.isAndroid
          A5.flags.isNotWebKit

            Re: Here Is A Method To Fetch The Browser Type And Version ...

            Well, when you google this, what I found was that getting browser information using js navigator can often produce misleading information and should not be used.
            That's why I said in my first post that it is not as simple as first seems, and it's why I didn't choose to use it.

            This is a direct quote from W3Schools:
            Warning !!!

            The information from the navigator object can often be misleading, and should not be used to detect browser versions because:

            Different browsers can use the same name
            The navigator data can be changed by the browser owner
            Some browsers misidentify themselves to bypass site tests
            Browsers cannot report new operating systems, released later than the browser
            I don't know if Alpha internally manages these hurdles or not. Maybe it's fine. Maybe not.
