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.

  • How to save multiple selections from a embedded browse

    I have a table with customer information and a table with components for a letter. The components for the letter are chosen in a embedded browse and these components are multi selectable. I would like to know what's the best approach for storing the multi selected fields. Each field (letter component) has a length of 100 to 240 characters.

    Werder,
    Because I have been following your threads, I can help with this a bit.

    If you took MikeC's approach to using and embedded browse to display the multi selections, then you have marked the records in the table. You have then the ability to filter the table for the marked records and generate a variable for each choice. You can open the table filtered, then fetch through the table and create a variable for each choice. It will require you to use a for-next loop and use the eval(), functions. I appended an example for you. hope this helps.

      Thanks for the example Mike. Do you also now if it possible to store the selected components for each customer and how this is done. Should I store the selected components (item_ID's) or should the text field (text1) be stored all together.

        Werder,
        Are you saying that the choices lists will be specific to a given customer or set of customers? If so, the item table would have another field with values somehow related to each customer so the table can be sorted such that the items presented would be customer specific. Is that what you are asking?

          I believe you understand me correct. The choices list will be specific to a given customer. It's like a customer who orders different products only in my case for each customer there are different letter components. Is this easy to accomplish or is it actually quit difficult?

            Werder,
            Not difficult.

            1. Added a customer table with customer ID.
            2. Added a customer_assign field to the items table
            3. Made customer assignments (cust_id) to the items.
            4. Made a customer select function to filter the items table for the chosen customer, clear the table and display the chosen customer.

            hope his helps

              Mike, I'm glad it can be done and thank you for taking the time to build an example. I will try to implement your concept within my database. Thanks!

                Re: How to save multiple selections from a embedded browse

                Mike, I like your example. However, have you considered what might happen if two workstations are trying to assemble different letters to the same customer at the same time? You might want to set an edit flag that gets raised by the first workstation, then lower it after the letter is finished. Your script could then alert the second user that someone else on the network is using the table. Otherwise, couldn't the text selected by both workstations show up in both letters? Or am I missing something?

                The select customer button clears all the selections in all the records. This, too, is problematic in a networked environment. Right?

                  Tom,
                  Thanks very much for the network perspective. As you can guess, I wasn't of a network mindset when I crafted this example. So, with a network mindset, I'd have to craft a different strategy. Thanks for the bump.

                    Mike W, a solution that works well in a networked environment would be a good addition to the Code Archive forum. Let me know if I can help. -- tom

                      Tom,
                      Scout this update out and see what you think. It is changed by:

                      1. The form is opened with selection of the customer up front and clearing check boxes as part of the current session (probably unncessary- see below).

                      2. I created a second form to mimick networking against one table.

                      3. The script that collects the currently checked items for the letter collects the items cycling through the browse records directly from the form Browse object and not by filtering the table and at the table level. I left the table level script and button in place so one could see the difference that you were referring to, and with opening the two forms and playing with the two methods.

                      4. So there are no true values generated in the table, the script that generates the letter runs a UDF that clears the boxes and this UDF also runs in the CanExit form event.

                      I added a script on the main menu button when opening the form to check whether the table is open as you suggested. I am not really seeing the need to have access limited with the new method. But I could be wrong. There is probably something missing for a network environment. See what you think, and thanks again for the bump to "think networked".
                      Mike W

                        Re: How to save multiple selections from a embedded browse

                        The way I have done this in a network is create a separate table w. user_id & record_id (of the 1st table). After records have been selected, I auto-delete that user's records (in the separate table).

                          Peter, that's very good. Hadn't thought of that. Tell us more about the sequence you use. Does the separate table get a new record after each "selection" is made? or do you wait until they've all been selected? How are selections made? What events trigger the new record(s) in the separate table? Thanks.

                            I use doubleclick on the browse.
