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.

  • Any built in capability to encrypt/obscure page variable in redirect URL

    When I use the built in A5 capabilities to open a new A5w page from an grid onclick event, and I need to send the key of the selected record, it creates a url like this:


    Obviously that is a bit of a potential security issue as a user could directly manipulate the url, perhaps setting a clientnum to which he is not entitled.
    What is the standard way to deal with this?

    I know that I can create a session variable, rather than a page variable, and set the clientnumber in that but as far as I know that requires a ajax callback to xbasic and then I have to define my own component filtering. I know that works, but I wonder if there is a better way.


    Perhaps something like this:'s

    Re: Any built in capability to encrypt/obscure page variable in redirect URL

    Here are a couple ways. You can add characters right in the URL like in my attachments and the use xbasic on the A5W page to extract the "good" value. Like you can use mid(id,5,10) to extract the ten characters starting at position 5.

    I often add a second unique ID to tables where I know I will need to link or use the "ID" in public. So my vendor_id might be 1,2,3, etc. But the "EID" (E for external) will be a 32 character GUID created when the record was inserted with remspecial(api_uuidcreate()).

    Then my link above might be mypage.a5w?i=c19fe68a92234952a087ddf4341281a9

    Since the EID is not a foreign key in any other table, I can mass-alter the values if I want.

    When your link is on an A5W page or fabricated using a Custom field type, you can be a lot more elaborate than above. But the onClick somewhat limits what you can do.

      Wonderful. Now I understand why some URLs seem to have these "garbage keys". It is not garbage!
      Thanks so much, Steve.
