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.

  • Tools and best practices to backup Alpha dbf and memo fields to avoid corruption

    It's my belief that backups should be run when everyone is out of the Alpha application. This is to avoid data corruption especially to memo fields.

    I'm looking to know what others are doing, both successes and failures.

    Is anyone using Microsoft's Azure?

    For what it is worth?
    I use a usb 2T external for back up and set the alpha backup for when I know it will not be in use. I urge my clients to do the same and set backup for 3 am normally. data files only.

        I hope your 2TB drive is SSD.
        I would believe data that needs to be backed up surrounding an application is more than just the data in Alpha. Our back up need consists of the data in our Alpha app (we named URSA) and many PDF files constituting quotes,vendor orders, invoices from vendors, invoices to customers, contracts, product MSDS and info, spreadsheet files, and lots more, all representing data that needs to be backed up. The entire thing is currently at 26 GB. The entire Alpha component is 202 MB. I have tried to write scripts to back up all the data, but they fail because I cannot get the the code to prepare the folders and subfolders beyond 6 subfolders. We have need for 8 levels of subfolders. So it is a physical copy the URSA folder in Windows File Explorer dragged to a 2TB SSD USB drive. It takes about an hour. Finian posted this script recently. I haven't tried it but will tonight.

        fmt1 = FILE_FIND_NORMAL
        strt = "d:\aaaa\bbbbbb\ccccccc" +chr(92)
        gfiles = "*.*"
        fmt2 = "PN"
        fname = "D:\temp\flist.txt"
        lst = filefind.get_recurse(strt,gfiles,fmt1,fmt2)
        zipfile = "D:\temp\"
        opts = "D,"
        if file.exists(zipfile) then
        end if
        res =,lst,Opts,strt)
        if res then
        	msg_txt = "The zip file was created!"
        		msg_txt = "The zip file not was created!"
        end if

          Mike: I don't think that script will work for you. It may create the files list, but I believe that the function will fail when the number of files is large. I tried it on a file list with 76,000 files and it failed consistently.

          As for backup in general, I have now used Acronis for more than a year and find it to be the most reliable, intuitive and easy to set up for local and cloud backup solution I have ever used. Come to think of it, I don't know why I'm still paying Carbonite when I have the Acronis cloud backup running once weekly without any issues. I rotate among 3 X 2T external USB drives and try to keep only one connected each day.

            Hi Finian,
            Thank you so much for that. I do not have 76,000 files, maybe 2000 files. My problem has been that I can create a text file that has the tree structure into a simple text file like:
            URSA>DC>doc_repository>Production>Stores>Audit_install_reports>PRJ.00646_GiantEagle_FuelPerks4th>Complete Installations>Store 1605>_1605_IR2.jpg
            The problem is I cannot reconstitute the file structure back into Windows using recurse functions that produces for that many subfolders.

              This was lost, so
              I have ssd on the backup drives and they cost less than 100 each. USB3.0 plug in and a very little setup.
              I back up the whole folder(s). That means, data, support files, pdf, txt and other that may be in folders.

              I actually thank a client for introducing these to me.
