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.

    Re: Conditional browse not properly filtering records based on another browse�s value

    I want to document the solution to the problem I posed yesterday. This breakthrough was made possible by my new understanding that Alpha Five allows parent and children records to be linked on compounded keys.

    Here is my revised set definition:

    tblPerson (Person_Id)
    ----tblPersonProfile (Person_Id, Profile_Id, 1:M)
    --------tblPersonProfileItem (Person_Id, Profile_Id, Item_Id, 1:M)
    ------------tblProfileItem (Profile_Id, Item_Id, 1:1)
    --------tblProfile (Profile_Id, 1:1)

    The 1:1 relationships are necessary to display the respective descriptions of the profile or of the item.

    I generated my default form before I added the 1:1 relationships, added these relationships to the set, then used the Toolbar's Drop List to place the description of the Profile and the ProfileItem in the two browses. The top browse is the equivalent to a set of tabs and the bottom browse represents information that would be displayed on that tab.

    The result is perfection!

    Below is a screenshot of the finished product.

    I will set the width of the Person_Id, Profile_Id, and Item_Id in the browses to zero and hide the Person_Id at the top of the form for a more finished appearance. I will move the description of the Item to the left of its value. But I have left them exposed to allow you to see better what I did.

    ALL WITHOUT A SINGLE LINE OF CODE!!!

    All this is embryonic, but you may appreciate that allowing your user to add their own profiles and to assign their own items to a profile (using a form yet to be developed), your user can effectively "customize" your Alpha application.

    This is ever more elegant that plopping down fields User 1, User 2, User 3, etc down on your form and allowing the user to change the labels.
