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.

    A useful utility, thanks Jim

    What would be really nice is to have a program which maps your production database, and maps all the field and index layouts. Then when you distribute the program you have a function which reads this map file and applies and data file change (field, indexes, new tables) etc as required as part of an upgrade.

    I have thought of developing this to put on Alphabay - Alothough I would like someone else to do it. It would really make job of deployin upgrades much easier.

      Re: Compare Two Databases for structural differences

      Bill Parker (of A5Doc) pointed me to this routine and I downloaded the latest version from Jim Chapman. I get an error in line 153 translating the path in A5v8 - screen dump attached. My drive G is native, not a network disk and is not shared as in Steve Bovino's posts.

      Any thoughts?

        I don't think Alpha and/or the coding likes an ampersand in the path. Can you rename that directory?


        Edit: Well, I just tested someithing I think is similar and it seemed to work. May be internal to the routine.

          Thanks for the thought. A5 has been working perfectly happily with the ampersand in the path for the last 18 months - it's just this routine that doesn't translate the path correctly.

          It's noticeable that the "g:" is missing in the errors line:-

          "Error loading g:\rbsd\clients...."

          "...cannot find the path specified. \rbsd\clients...."

          i.e. the drive letter isn't being parsed.

          I'll try it in V9 on my machine but the client is using v8 and isn't likely to upgrade.

            Problem solved. I had imported the two copies of the database from the client's site and put them into new folders on my pc. The drive and folder names didn't match those on-site and I ran the utility in a new database without having previously opened the two imported databases.

            It seems A5 rebuilds the pathnames internally when you open a copied database. As I hadn't opened them first the utility was trying to find the original paths which weren't available to it on my machine.
