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.

    Is It Possible To Use Show/Hide Expressions In Reports?

    Say I want to conditionally show/hide a control in a report, is there a way to do this? It is not jumping out at me if there is :-/

    Re: Is It Possible To Use Show/Hide Expressions In Reports?

    Are you building an active report with live controls?

    One good way to show or not show something on a report is to make a calculated field, then use the results of that calculated field.

    Reports also can have conditional objects.

      Hmm, no it's not a live report, it is based on a SQL query.

      Ideally I'd like to hide a Frame object in the report based on the value in another control. I haven't figured this out yet.

        Try this:

        Make a new report in Northwind

        Datasource is the Categories table, select the CategoryName field

        Make the report, put the CategoryName in the detail section.

        Put a frame around the CategoryName field.

        From the Task List on the menu at top, select Properties.

        Click on the Frame and the properties for the frame will show.

        Find the Layout/Visible property and click the plus icon to expand your choices.

        Set the Visible property to Dynamic with this expression:
        CategoryName = "Confections"

        See if that suggests a solution.

          Steve,

          Yes that works! That is exactly what I need to do.
          I was missing the part about Task List properties .. I never saw those extra properties until you told me that.

          Thank you sooo much! I am ecstatic, I worked on this all day and got nowhere.

            One thing I notice doing this is the whitespace does not collapse when the controls are hidden (see image).

            Do you know if there is another property buried somewhere to collapse the whitespace?

              What type of controls are they? Is this like a large text box?

              Each text box has an allow shrinking option - you could try that.

              What I often do is make my text boxes small and then allow growth. That will allow them to grow as large as they need to when they are filled and showing, but when I hide them, they take up little room.

                I think you're beginning to see why I prefer, when possible, to just construct reports by hand-coding the HTML.

                Alpha's report writer is terrific, but once you learn to just code your own these little things are more easily managed.

                As for the white space in what you're building right now - not sure, and I'd have to try. And I'd work with a variation of what Larry suggests - put the data into a Rich Text object that can grow and shrink as needed.
