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.

  • A5 and SQL

    When A5 is used with a link to a SQL table does A5 need to be installed on the server or is just the client (desktop) install necessary?

    Active Link tables are on the client (desktop) so as far as I'm aware there is no need for any shared tables or other files to be installed on a server... the only thing that happens/is located on the server is the SQL database.

      Russ,

      Hope I am right on this, but pretty sure I will be proven right by others. I played with it in v9 and v8, but had no server setup. The link would be in the db on the workstation.

      Create your sql tables on the server just like your dbf files. The workstation will need a5 and sql server. If you set them all up the same with pathing etc, and the same sql queries, it will work fine.

      If you put sql tables/files on the workstation, no one else can see them and they would be stand alone.

        it is not necessary to have sql server on the workstatioon where the client is. The server may be anywhere you like (network, webserver). You set up the connection to the sql server wherever it may be when you establish the active or passive link

          Not quite...

          What you need is a SQL database server on the network (mySQL, Oracle, SQL Server, Postgres etc.) and a connection string in the A5 app that either uses native SQL drivers or an ODBC driver (this may require client software for the SQL database to be installed - usually Alpha just prompts to download an "instant client" or similar) to connect to the database... No need to install any SQL or other database server on the client machine at all.

            And SQL Server is just one of many database systems - mySQL is a free SQL database for example, as is Postgres...

                Documentation/completed help files would've probably helped too ;)

                (I haven't actually used our RTs for V8 or any other RTs, ever - managed to pass those on to the chap who kept demanding me to finish this project for him without any specs or feedback or other info, whatsoever... at last! ;) )

                  Re: A5 and SQL

                  The reason I ask is that if A5 does not need to be on the server when used with a SQL data store, then Alpha would not seem have have control over user counts. I think this ties into the whole discussion of pricing etc. I don't currently use SQL except to play a bit with MySQL but have thought that it might be nice to use if there is some advantage.
                  It seems (my opinion) that a lot of stuff is done in SQL that doesn't need it, but it appears most companies don't think of DBF as a real database solution.

                  Anyway, if Alpha can't control the number of users connecting to a SQL table with Alpha, it would seem that a desktop or 1 user runtime becomes unlimited with SQL. Alpha has to find a way to get compensated for their work. Maybe the route chosen has some deficiencies, that I'm sure will be corrected but they do need a revenue stream that does not depend on charging a huge price for the developers version. That would also drive away developers.

                  I have heard it said that Microsoft owes their success, more than anything else, to their courting of developers. I remember back years ago, before Microsoft was dominant, they were always having conferences and stuff that was free to attract developers. Borland, IBM, Novell, none of them could or would match it. Developers are key.

                  Maybe Alpha should give the developer version away free and just charge the end users! (Just kidding, i don't really think that would work.)

                  I may be wrong on this but it seems logical.

                    Indeed that is as far as I can see the thinking behind the currently published RT pricing, but it's obvious from earlier posts and the prompt response with an OEM model "flat price" that they are looking at things to see if there isn't a better, more affordable way to allow non-SQL apps to be deployed from A5 without the same restrictions they have to, by the sheer nature of a client server app plugging into one or more SQL databases, implement for the full whack Enterprise RT package...
