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.

Terminal Server Shadowed vs. Not Shadowed

    Terminal Server Shadowed vs. Not Shadowed

    We are using a Terminal Server to allow remote access to an A5v9 app. The data and application files are not on the Terminal Server. They are on a data server (not a NAS) on the network. For local users (those not connecting via the Terminal Server) we have all users connect to the database using shadows. I am looking for input on if we should have the Terminal Server users connect to the database using shadows or run the application un-shadowed.

    Hoping to gain from other's experience, thanks for the help,

    Re: Terminal Server Shadowed vs. Not Shadowed

    In the situation you describe opening the database (e.g.,autoexec script), opening layouts (forms etc.) all have to travel across the network if you do not use shadows. Not true if you use shadows, so using shadows should be somewhat faster for those kinds of things. I just did a crude test on a TS setup like yours ("one thousand on, one thousand two") and using a shadow was at least 1 second faster in getting my starting menu form open. Of course speed differences all depend on what is going on in the autoexec and any layouts you open. In one of my other more complex autoexec forks I am sure it would have been 2 or 3 seconds faster using shadows.

      Hi CP,

      I have a client that has over 40 users on the network, some inhouse and some in two remote offices. The users in the remote offices are on TS and the only problem reported is the use of graphics on forms. This I have been told is a windows issue.

      The bottom line is the quality of the TS.

        Re: Terminal Server Shadowed vs. Not Shadowed

        We have remote users log on to the server and auto load the adb, so we do not use shadowing. And we have T/S on the server. I think if you have to cluster servers, then you may need to shadow.

        - Keith, have you migrated to Server 2008 R2 yet?

        We are going to get a new server maybe Sept and move to it - supposedly they have a new universal printer driver that is friendly to a wider variety of printers than 2003. The graphics may be better, too. The thing about graphics is that to get better more data has to be sent to the w/s.

          Hi Martin,

          I think they are still on 2003.

          Thanks for the tip, I'll pass it along.
