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.

    Sort_Array vs. Trace window

    The following script fragment works fine:

    Sort_Array("fNames")
    ui_get_list_array("Files",1,"fNames")


    This script also works:

    For k =1 to i
    trace.writeln(fnames[k])
    Next



    This script fragment does NOT work:
    Sort_Array("fNames")
    For k =1 to i
    trace.writeln(fnames[k])
    Next


    Why won't the trace work with the sort?

    RE: Sort_Array vs. Trace window

    Peter, you don't explain what is not working.

    Is nothing being written to the trace window?
    Is the trace window list unsorted?

      Tom,
      Nothing is being written to the trace window. In other words, if I don't sort, the values are written to the trace window. If I sort, no dice.

        Peter,

        seems to work ok from the interactive window.

        this prints the sorted list to the trace window just fine.

        dim color[3] as C
        color[1] = "Red"
        color[2] = "Blue"
        color[3] = "Green"
        sort_array("color")
        for i = 1 to 3; trace.writeln(color[i]);next i
        ?color[1]
        = "Blue"

        ?color[2]
        = "Green"

        ?color[3]
        = "Red"

        -- tom

          I know. I can do a similar test both interactively and from a script. Just not with the values that I actually need. Really wierd!

            Peter,

            this works fine from a button on a form, too.

            ''XBasic
            dim color[3] as C
            color[1] = "Red"
            color[2] = "Blue"
            color[3] = "Green"
            sort_array("color")
            for i = 1 to 3
            trace.writeln(color[i])
            next i

              Peter,

              do you explicitly refer to the counter [k] in the 'next' statement? I recommend it.

                Peter, is it possible another process on your form is clearing the trace window?

                  Thanks Tom,
                  Problem solved: The array variable was set to an arbitrarily high value (1000). The actual value of k was around 150. When I sorted the array, the top 850 values were blank! Thus, when I wrote to the trace window I was getting nothing since k stopped at 150 and those values were blank with nothing to write.

                    Glad you recognized the issue.

                    Once again Alpha Five does what we tell it to do, not what we "intend" for it to do!
