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.

  • How to Get System IP Address in Alpha Five Web Application

    Hi
    I am working on Alpha five Web Application. I need to show a report of the current logged in users (user name & IP Address), few questions on this:

    1. I can track the login and insert the details in a database, and when the user logs out , i can delete the record, but how do i handle session expiry, i mean when a user logs in, i add a record to the database, then before the user logs out, the session expires, so the logout code doesnt get triggered, the record that i have inserted will remain in the table. Please advice.

    2. How do i get the IP address?

    Thanks in advance...



    Cheers
    Vasan.

    everything = request.raw gives you everything if you want it.

    ip=request.remote_addr give you just the IP.

        This is ok for people not behind certain firewalls, it is very well documented over the web to use code like this vbscript:

        ipaddress = Request.ServerVariables("HTTP_X_FORWARDED_FOR")
        if ipaddress = "" then
        ipaddress = Request.ServerVariables("REMOTE_ADDR")
        end if

        however I cannot find alpha supports HTTP_X_FORWARDED_FOR

        any idea how to achieve this?

          Antony,
          Does that vbs work? I just tried it but probably out of context. Anyway, if the vbs does work and there is no equivalent in Alpha, then it is possible a couple of ways to run a vbs script from within Alpha (will be as though you double-clicked on it). Alpha has a function that runs a vbs or you can use sys_open().

            A5V9's equivalent would be Request.HTTP_X_FORWARDED_FOR if the header has been set. If not, the variable will not exist, so you will want to use eval_valid() to see if it was part of the request.

                I have a file I include in the relevant pages using a5w_include() that does this:

                Code:
                <%a5
                Dim IpString as c
                IpString = Request.Remote_Addr
                
                If smatch(IpString,"pattern1.*") = .f.  then
                    Response.Redirect("login.a5w")
                end if
                %>

                  This code is placed on what conditions? whether the "CanInsertRecord" or "CanUpdateRecord" or on page a5w?

                    It would work anywhere you placed it. What are you trying to accomplish?

                        If you have a login dialog on an A5W page, you can use this syntax to only grab the login information when they click the Submit button. It will be stored in v_ip, and then you can do whatever you want with that information. The syntax below will work in V9 and beyond:

                        <%a5
                        'gets the username and IP address
                        if eval_valid("submitbutton")
                        if eval_valid("userid")
                        v_userid = userid '== the username they used to login
                        v_ip = request.remote_addr '== their IP address
                        end if
                        end if
                        %>
