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.

    UML modeling

    Is there any point to utilizing UML when designing an Alpha app? UML is geared for OOP languages. Som UML programs will acutually produce code and objects from the model. I realize that it's not possible to do with Alpha, however it might be good practice for documentation purposes.

    RE: UML modeling

    Hi Terry,

    Whatever you refer to them as: UML, Schema Designs, Achitecture Specs, ect....

    Yes,Yes,Yes. The more detailed your pre-production efforts become. The more consistant your designs will be and the more equipped you will be to revisit the sysetem for upgrades at a later date.

      RE: UML modeling

      A lot of the advantages of UML are not available for A5 but it is a standard and, as Marc points out, the more detailed your design, the better results you're going to get.

      Back before the code-generation tools were any good, people still used design languages with great effect--just a lot of up front leg work.

      And it is possible (though challenging) to code A5 in an object-oriented style. Whether or not it's worth it probably would depend on how good your design doc was.

        Thanks,

        That's the answer I hoped to get. I love A5, however after using Access for many years, kicking around Visual FoxPro and Delphi, is miss some of the ease of code re-use and inheritance. Access doesn't really have inheritance, but I found it easier to manage the code modules. However, A5 is by far the easiest Db to make apps with, I suppose libraries in A5 can bu used the same way as a module. I'd be interested in how others manage apps with many global UDF's.

        Thanks - Terry

          Boy, you're telling me? :-)

          I hear ya.

          However, A5 is by far the easiest Db to make apps with,

          Delphi is broader and deeper than the other products mentioned, and its database scheme is more "detached" or "abstract", so it is, in that sense, "harder". I've found, however, that the greater the extent of the project, the less important, em, instant gratification becomes, and the more important traditional programming tools (things that increase robustness, flexibility and maintainability) become.

          I suppose libraries in A5 can bu used the same way as a module.

          I don't know Access well enough to say. I need to experiment more with A5's libraries, too. I've managed to encapsulate certain code in A5 subforms as a sort of kluge to get inheritance, too.

          I'd be interested in how others manage apps with many global UDF's.

          So far, we've been keeping our routines separate and just sort of going "OK, I changed 'routine x'". Or more likely, "Here's everything. I don't remember what I changed." It's a work-in-progress. Heh.
