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.

    Scripts and Functions

    When I look at AlphaSports, and (in some cases) many of the comments on the forum; I see many, many small scripts and functions. I have not yet been able to 'formulate' a mindset as to the point of writing a small script for an event as opposed to 'running' a small script/function for that event.
    Since the value of either side is still questionable (to me); I have no aversion to either side...
    My point in the form of a question:
    Other than the ability to call a script or a function from an event; what is the 'gain' over just writing the script as part of the event? Especially if there is little or no chance that the particular function/script will be used in more than one place???? Example..... calling a sub-menu or a form from a button on a menu. If that menu is the only place that the 'calling' will occur, why clutter up the code section with a script/function?
    Now if you have a particular 'handling/processing' of data or forms that re-occurs several times and from several different locations - OK use a function or a script, cuz that way you only write it once...
    I can see some similarity between Cobol 'performs' and functions or calling scripts and it might be a little less 'cluttered' in a long script to call a function but what else is gained????

    Don't need a long dissertation, just a few short comments will do.

    thanx in advance for any time spent to clear 'the mud'

    Debugging a script or function that is not stored in a form is more convenient.

      Other than reusing code, this is one of those personal preference areas.

      If you are writing commercial apps, there are some code security issues you may want to consider. Try searching for security to get the threads that address the issue.

        RE: Scripts and Functions

        Some prefer the organizational benefit of having all code on the code tab instead of scattered about forms, buttons, etc.

        During development, you can keep your form open, edit your script/function in the script editor, save it, then click the button on your form to test it. This is much easier than changing the form to edit mode, editing the button event, saving the event code, saving the form, then going back to view mode.

        Code in the code tab can be compiled into an AEX. This provides benefits when distributing your app.

        When you app is in use, you can distribute code updates by simply updating the .alm instead of worrying about updates for the individual tables.

          As a follow-on to Lenny and Ed, if the code is on the code tab, and you have a specific thing to do each time you hit, say "return" in every form in your database, then the code option makes for much less chance of writing that piece of code wrong under one button. All you do is to use the named script.

          It can save you lots of time.

            Thank you all for your comments...
            I can see that it would probably be better under the code tab....
            Also, noticed that AlphaSports tutorial recommends keeping OnPush and OnChange events as 'run a script'... or as they said 'separate from the code'...
            Thanx again
