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.

  • Return to Previous URL (two screens ago)

    Hi,

    I have seen on a past post (from Steve Wood) that you are able to go back to a previous page using the following;

    Code:
    It will work if you put this in your initialize event:
    
    if eval_valid("request.referer")
    session.page = request.referer
    else
    session.page = "anerrorpage.a5w"
    end if 
    
    and this in your aftervalidate:
    
    CurrentForm.RedirectTarget= session.page
    
    You only need the else..errorpage.a5w part if you want, probably not necessary under normal circumstances.
    However, what i am trying to achieve is slightly different.

    1. The user selects the search Grid (Page 1) and say lists all companies beginning with A
    2. Then the user selects one of the companies, this sends them to a contacts page (Page 2)
    3. The user then selects the contact and a dialog appears (Page 3).
    4. The user adds some data within the dialog form and then submits the page.
    5. I now want to return to the first grid result page (Page 1).

    I can redirect back to that page, but i will loose the filter results. I want to be able to get back to page 1 complete with the results from the initial filter. I suppose it would be like clicking BACK twice.

    Can anyone help?

    Thanks

    Denis

    I managed to sort it.

    I created another a5w page with some javascript code and redirected my dialog to that.

    Code:
    <script language="JavaScript" type="text/javascript">
    javascript:window.history.go(-3);
    </script>

      Hi,

      Due to some additional screen clicks in between Page 1 and 3, the javascript go back 3 screens is not always appropriate. Does anyone know a way where i could specifically specify the page to return back to.

        On the page you want them to go back to, set:

        session.pageiwant=Request.Script_Name

        script_name is the name of the page they are on, like "index.a5w".

        Then use that session variable in a link or response.redirect() on the page you want them to bounce back from. To recreate the initial filter you can either, depending on how you filtered in the first place:

        - on the original page, save the filter text to another session variable and then reapply as a page variable when they go back. (Not sure how you would do the first page, depends on how you set the filter).
        - take a look at the URL on the original page. IF that URL includes the filter syntax, then user request_uri instead of script_name and it will include the filter syntax.

          Thanks for the reply Steve,

          Where on the return (original) screen should I place session.pageiwant = Request.Script_Name.

            Anywhere. Inserting it at the top is best.

              Hi all ,

              The page that I'm supposed to add "session.pageiwant = Request.Script_Name" at the top is a page with "requires login" security, so I apparently the code, "session.pageiwant = Request.Script_Name" didn't get transacted before I was directed to my login page.

              SecurePage.a5w
              1. Add "session.pageiwant = Request.Script_Name" at the top

              LoginPage.a5w
              1. After successful login, redirect as session.pageiwant

              Anywhere else I can get "session.pageiwant = Request.Script_Name" transacted before I'm directed to my login page ?

              Thanks.

                Jim,

                This is a six year old thread. I am sure the desired method has changed -- please start a new discussion and tell us what you are trying to accomplish.
