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.

    Upgrade My Personal Application

    Re: Upgrade My Personal Application

    Hi Cristiano,
    The data for A5 is stored in the .DBF files/tables. Do you mean you currently have A5 v8 & you are about to upgrade to A5 v9? Apha five v9 will open the database you created with A5 v4 - v8 without any problems. A good practice to maintain is to make sure that all your database/application files are stored in a different folder/directory from your A5 Runtime files. Install your new A5 v9 in a different folder than your existing A5 v8 to avoid any conflict with the two versions. After you open your old database with the new A5 v9 the first time, perform a database compact from the file menu. This may take sometime depending on the size of your database and the data contained in it. Goodluck.

        Christiano,

        If any of the tables contain memo fields, the memo field data is stored in a separate file. This separate file has the same name as the table, but an FPT filename extension. You should be careful not to overwrite any FPT files that may exist on your customer's machine.

        Also, be aware that the customer index file for each table (CDX extensions) on the customer's machine will be different from yours, since they have live data in their DBF tables. If you overwrite their CDX files you will break all their indexes. This would require you to immediately rebuild all their indexes. Often this step can be avoided simply by not overwriting the CDX files.

        Does this make sense?

            Cristiano, one more thing. If your app implements a security framework for the user, the user's passwords and group settings will probably be very different than what you initially developed. I am not certain, but I believe these settings are stored in the database dictionaries. If you overwrite the customer's database dictionaries you will very likely cause them to have to reconstruct their personalized changes to the security framework.

                Re: Upgrade My Personal Application

                Thank you all for your suggestions,

                but I have another question now, my software( for a bibliotheque) work with a Set (primary table and 3 others tables that are linked by a common field 1 to 1 and 1 to many).

                Now my question is this: I need to make very attention to do not overwrite the: BDF and CDX files, and which others files ?

                I checked on my local computer , when I put it on the new version with only the DBF files, the form created to my principal SET they have incorrect the linked tables .

                Now, I need perhaps to recreate or update index from my local computer before to upgrade to my client ? And my client, will continue to work with the old software increasing, so, all the tables and the set or will stop its work until I will upgrade to the new version?

                Thank you for your patient and , also for my very bad English
