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.

Can a web application be available on both a LAN and on the internet?

  • Can a web application be available on both a LAN and on the internet?

    I have developed an A5 desktop application that typically has no more than 2 - 3 users. I am considering re-writing the application to be a web-based application that is run from a browser. I perceive the following advantages to doing this:

    -- The application would support more simultaneous users without contention/corruption issues.
    -- The application would be more easily accessible over the web than using tool such as Logmein or Windows Remote Desktop.

    For a user, however, the application will be slower if the database is located on a server that requires internet access. In addition, if the internet is down, the user is out of business. Therefore,

    (1) can the application be configured to run on a local server with access provided to local users over a LAN, while simultaneously allowing remote users to come into the application from the internet using a browser running on a remote computer? And,
    (2) can the local server OS be Windows7, or does it have to be a Windows Server OS?

    I may be mis-understanding how this all fits together, so any help is appreciated.

    You certainly can you would just point the internal computers to something like I did this on a v10 site with server2003 but I cant imagine that it would be a problem on any windows operating system that can run the WAS

      Definetely it can be done without any problem on Windows 7 (or XP by the way).

      LAN users will always see your Server and you need to configure your router for INTERNET users to see it.

        Speed will certainly be an issue for internet users if you run it from your internet connection as your upload speed is limited (at least that is what we have here in belgium). I would go for a VPS with a company like Zebrahost for all users or is your internet connection so unreliable?

          Does A5 Web Application Server v10/11 provide sufficient security or do I need to consider other more robust means of security when I open my server up to the outside world?

            In reply to a couple of the posts above.
            We use the redirect after login for internal and external users, it works well without any security issues.
            On another note about speed, we host the external site ourselves now but had to install a 10mb fibre link for it to work well enough without speed problems.
