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.

  • Does Commented Out Code Still Require Resources

    This is just a general question about whether it is generally better to remove unused code versus commenting it out.


    I'm sure we all do this now and again:
    Say you create some code in an event handler someplace. You then decide for whatever reason you no longer want to use it.
    So you comment it out (in case you might want to re-use it again down the road .. you might not).


    I'm assuming that the browser still needs to actually read that code to determine that it needs to ignore it?
    If so, is it better practice to actually delete the unused code rather than simply comment it out?

    I believe that when you publish a component, it removes the commented code, especially if you select pre-render. So it does not affect published components. So, commented code only makes the publish process a bit longer....probably not noticeable.

    If you look at the source code for a running page, you will not see any commented code.

      Thanks Pat, I didn't know that but it makes sense.

        Hello Stephen,

        Code comments do require space in the file, but they're not computed when the code is interpreted.

        If you are resistant to deleting code but don't want to execute it in your scripts, I highly recommend that you use a source control system, such as Git or Subversion, with your projects. Source control systems will track the changes to your files, allowing you at any time to roll back or check out past revisions. This makes it very easy to retrieve code you previously deleted. Using source control is also a recommended best practice when building software systems.
