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.

Lock out all network users

    Lock out all network users

    I have an application that is run on a network with about 8 users.

    I have an autoexec script that is set to run the first time the application is started each day. This script runs an aging script as well as rebuilds all indexes in the application. It is only done once each day.

    The script takes several minutes to run and if any other users starts the app while it is being run, it generates errors for both users.

    Is is possible to lock out all other network users while this script is being run?

    Thanks

    Sure. Just send a signal and auto-close all logged in users except yourself.

    To wit:
    • Main menu form that users cannot close w/o closing A5.
    • Main menu OnTimer event that checks a certain value in a table or text file (I use a text file w. a 0 or 1).
    • Set the Main menu timer interval to some value like 60 seconds.
    • If the text file or table value = 0, shutdown A5 (except Admin copy) from the OnTimer event.
    I also have a special table that shows me who is logged in or out at any given time (not required). When the coast is clear (which should be within 60 seconds of initiating the 0 save), do what you want.

      Re: Lock out all network users

      Is there a way to send a message to all users who are logged on (via Alpha5)?

      We have recently run into a problem where 2 people generated invoices at the same time and it caused cross posting in the invoice table. It is a fluke that has just happened once in 15 years but I'd like to be able to warn other users when someone is generating invoices so they don't do it at the same time.

      Thanks

        I've usually not used a warning for those types of controls. (most users determine that warnings are for everyone else)

        Instead you may need to be more forceful about it.

        Consider having a file that is checked prior to the invoice generation. If the file is there, a message is sent that someone else is alrady invoicing. Then when the invoicing is done, the file is removed and others can invoice.

        You could also write into the file who is doing the invoicing.

        Another option is to do the same thing using a record in a table.

        I'm sure there are other ways of accomplishing the same task.... and we'll hear about them here....

          I appreciate the advice.

          I was able to use this logic to solve both of my issues above.

          Thanks!

            Just be aware that a simple shutdown like this won't work if there is a form open in "dialog" mode or a modal (std?) xdialog is open. It can be done but only with additional coding within each xdialog and "dialog" form that might be open.

            Edit: I think the app will close when the xdialog or "dialog" form closes but if it's open and the user walked away, it won't shut down.

              That's good to know, Cal. Thanks.
