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.

    When should we use JavaScript and when should XBasic be used?

    Hi,

    In alpha when do we use JavaScript and when should XBasic be used?
    Are they used together?
    Can one be used instead of the other?
    Can anyone post a short problem where each was used, and explain the advantages/disadvantages over each language verses the other?
    (sorry if this is starting to sound like criteria for a college paper!).

    Thanks

    Re: When should we use JavaScript and when should XBasic be used?

    In general, javascript is used on the client side, e.g. when you want something to happen right in the user's browser.

    Xbasic is used on the server side.

    Now, a usual combination of the two is when you want a client-side event to do something that has to do with server-side processing. To do this, you use an AJAX callback. A callback is an AJAX call to an Xbasic event; the Xbasic often returns something (which has to be javascript to execute in the browser) or it can simply run a process on the server.

      Steve:
      Thanks for the explanation; I'm still absorbing what you wrote.

      Can anyone give an example of a problem that you might want to accomplish with JS, XB, and both... i'm trying to figure out in my head, yet not knowing anything about JS/XB I'm a little brain frozen.

        my question is also probably going to extend to "What is JQuery, and how is it different from JS"... but that might be a different post if necessary.

          If you want to manipulate tables (either dbf tables or SQL tables), or fetch data from a table, Xbasic is the ticket.
          Javascript can be used to manipulate the contents of the browser as Steve said. JS can get and set values in the browser, and you can use Ajax callbacks to feed values to tables and get values from tables to set in the fields in the browser (I said the same thing Steve did, really).
          You would really benefit from watching some of the videos on:

          And Steve's videos are excellent too.

            Thanks for posting... sometimes i need to hear things in a slightly different slant before it settles in my head... Both of your explanations answered my questions... going to watch the videos now.
