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.

Setting session variables

  • Setting session variables

    Hello,

    I have several session variables session.v1, session.v2 etc. I am looping through a table and have a counter within the loop. What I'd like to do is assign the session variable's number part to the counter, something like

    While flagloop
    session.v + Counter = rs.data(1)
    end while

    so first time through, counter=1 therefore session.v1 = rs.data(1) the second time through, counter=2 therefore session.v2 = rs.data(1)

    how can I accomplish this?

    Thanks

    -John

    Re: Setting session variables

    Not clear what you are trying to do here so just guessing but sounds like you need to use a for loop

    dim myvariable[0] as c

    while (rs.NextRow())
    count = count + 1 // Get total count of record-set
    myvariable[] = ""
    ... do something else
    end while

    While flagloop
    FOR i = 1 TO count STEP 1
    myvariable[count] = rs.data(count)
    NEXT
    end while

      Re: Setting session variables

      Hi Alex,

      Thanks for the reply. I'm having a hard time trying to explain this. It is kind of like what you said except I need to use session variables and I don't (think) I need an array. I don't see anything that explains how to do this with session variables. The only option I know (because I don't know any better) is something along the lines of:

      psuedo:

      loop begin
      count = count + 1
      If count = 1 then
      session.V1 = rs.data(1) ' it is always rs.data(1)
      elseif count = 2 then
      session.V2 = rs.data(1)
      ....
      end loop

      but that seems ridiculous if I can just set the session variable like session.V(count). If I can do something like that then I can have simpler code:

      loop begin
      count = count + 1
      session.V(count) = rs.data(1)
      loop end

      Ideas?

      Thanks

        Hey John

        If you want a way you could do this

        dim args as sql::arguments
        dim count as n = 1

        while (rs.NextRow())
        count = count + 1 // Get total count of record-set
        args.add("arg_count",count)
        template = "session.V{arg_count} = rs.data({arg_count})"
        mergetemplatewithargs = replace_placeholders_with_argument_values(template,args)
        EVALUATE_TEMPLATE(mergetemplatewithargs) 'Edited Originally eval(mergetemplatewithargs)
        ... do something else
        end while

        using args to ensure limit the risk when using the eval function

        love for anyone else to comment on any other solution john could use
