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.

    3 new sample web app pages

    We have added 3 new sample pages to our samples at http://was.alphasoftware.com/web_applications_demo/default/

    1.15 demonstrates adding checkboxes to select multiple rows from a grid. A mailing label is then generated for each selected customer. It also demonstrates opening a new window to a specific size and turning off toolbars to display the labels in.

    1.16 demonstrates using a radio button in your grid as a row selector. Multiple actions can then be performed on the selected record based on which button the user clicks. Also has the new window functionality of 1.15.

    1.17 demonstrates creating a bar chart in a grid from a calculated field.

      The error did not come from the demo pages, but from an error in a different application, the demo Web Scheduler. Lenny has been notified and corrections sent.

          Lenny,

          looks terrific!
          I would like to see how you built the pages, but all I can find is notes that don't help me enough because I don't have the skills to invent things my self. For the moment I rely on Monkee-see-monkee-do. Will they show up in the WAS demo database one day?

            Yes, they will be added to the Web Applications demo. If you're interested in duplicating the bar chart, I created a sample database for Howard Cornett which you can find here.

            If you'd like to know how to do the checkboxes or rasdio buttons, I can provide addiitonal instructions.

                  Hi Lenny,

                  I am especially interested in the checkboxes, exactly for the purpose of printing letters and labels. I read a little bit in the a5w-code already. Quite complicated but I think I understand globally how it works.

                  If you have additional info: always welcome!

                  Greetings, Ren�

                  P.S. I go to bed soon, and this weekend I don't have much time, so don't feel obliged to hurry, please!

                    RE: 3 new sample web app pages

                    Here's a description I wrote up for the radio button example previously. The checkbox technique is essentially the same. The only difference is that the variable used for the checkboxes is an array so that multiple records can be selected.

                    What I have done is created a freeform layout for the customer_id column to create a radio button. The layout is


                    I then created an A5W page with this grid component on it. I went to the table cell that had the grid detail part, inserted a form, then dragged the detail part into the form so that the radio buttons will be contained within it.

                    Create as many submit buttons as you wish. They should all have the same name, but the values will vary based on what you would like displayed on each.

                    Set the form's action to something like ActionFromRadio.a5w

                    Then when one of the buttons is clicked, ActionFromRadio will be executed. It will have a variable named the same as the buttons and you can conditionalize your action on this value. You will also have the cust_id available to you for a query, etc.

                      I should be able to create some nice handy things now. I'll let you know.

                      Good night!

                        As you start building your Web Apps we would consider adding them to the Sample Web pages (you can use dummy date to protect confidential info that is not meant for the public)

                        If you are interested - please contact [email protected]

                        We will of course include your contact information which should result in leads back to you and you being "positioned"

                          This is Awesome! Are you also looking at creating line charts?

                            A line chart would be considerably more complex.

                            The bar chart takes advantage of the fact that each bar is essentially a separate rectangle. Given this, you can use a simple image of a square and scale it as needed.

                            For a line graph, you would need to know coordinates for the data points, then dynamically create lines to connect the points. ui_bitmap_draw() gives you the core functionality for this. Once you used ui_bitmap_draw to create a graph, you would save the image under the webroot and include it in your page.
