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.

  • Alpha 5 Runtime

    A few general questions for Alpha 5 runtime application.

    1. Does an Alpha 5 runtime application for distrubution include tables, forms, browses, etc within a single executable file or are all these objects separate files?

    2. The application I have in mind is more like a database container where the user looks up info. No data entry is permitted. Can I protect this info from someone trying to open it with another program and siphoning off the data?

    3. Can the data in a table be decrypted/encrypted automatically when the app opens/closes?

    Hmmmm. Maybe someone else knows more than I, but to the best of my knowledge:

    1. It's exactly the same as what you develop using the full version of Alpha Five. The Run Time engine is the same as the full version with the development features disabled or removed.

    2. There may be a way, but it isn't built into Alpha Five version 4. That's promised for a future version, perhaps version 5.

    3. See number 2.

    The latest guess on when version 5 will be out is 3rd quarter of this year, but that's not an official estimate.

      RE: Alpha 5 Runtime

      An Alpha application is not an executable, it consists of tables, sets of tables, and associated files containing indexes, layout definitions, etc. Runtime users cannot make changes to layouts, add index definitions, etc.

      Alpha tables are Foxpro 2.6 compatible, thus they can be accessed by many other database programs, utilities which can read such tables, even Excel. You could design an Alpha application which did not allow data entry.

      Using the xbasic programming language, included with the developer version of Alpha, you could, conceivably, encrypt and decrypt the data stored in your tables
      There can be only one.

          RE: Alpha 5 Runtime

          You might want to look at Lotus Approach, the database component of Lotus SmartSuite. It uses .dbf format files (although it can also open and use a variety of other formats) and you can set it up so that users can view, but not edit data, and you can password protect your data so it can't be opened by other applications.

          Specifically, you set up security by going to the File, User Setup, Approach Preferences..., Password tab.

          Approach ships with Lotus 1-2-3, or as part of SmartSuite, which you can find at very reasonable prices on some of the online auction sites.

          I prefer Alpha Five for a number of reasons, but it sounds like Approach might do the things you need.
