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.

  • Request.host

    Is Request.host a valid (secure) way of verifying the request comes from localhost? It returns localhost when run from localhost, so that seems to work. I basically need to restrict access to a certain page from only localhost and no where else.

    Re: Request.host

    "Secure", no. But it may still be "good enough" depending on your level of concern.

    Request.Host will contain whatever is used in the host portion of the URL to access the server. To access the local machine, you can use localhost, 127.0.0.1, the local machine name, any other IP address that belongs to the local machine, or any other partial or fully qualified host name that resolves to the local host.

    You can alternatively look at Request.Remote_Addr, which will contain the IP address that the request came from. This too will vary depending on what URL was used to access the server, but it will always be 127.0.0.1 or an IP address belonging to the local machine if it is a local request and save you from dealing with host names.

      Re: Request.host

      Remote_addr is probably what I'm looking for. I have an a5w page that runs some xbasic code as a 'nightly' routine using the task scheduler and powershell to open the page in Windows. Right now I am using an 'access key' as a request variable, but I was thinking checking against 127.0.0.1 might be better.

        Re: Request.host

        I wasn't quite thinking clearly when I answered yesterday. What you want is Request.IsLocal. This operates at the socket level and is always able to correctly determine if the request is coming from the local machine.

          Re: Request.host

          On V12 it is important to use Request.IsLocal rather than determining if request.remote_addr = "127.0.0.1".

          Here is some sample code from an app that is designed to work in V10, 11 and 12:

          dim is_local as l = .f.
          a5ver = floor(val(version("v"))) ' get the Alpha Five version
          select
          case a5ver < 12
          is_local = if(request.remote_addr = "127.0.0.1",.t.,.f.)
          case a5ver > 11
          is_local = Request.IsLocal
          end select
          if is_local = .f.
          ...
