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.

  • System Unbound

    Could someone please tell me what's the Unbound (found in System in Drag & Drop list in Design mode) is for. Is it a free field of some sort or a variable or...? When placed on a form it seems to act as a variable, placed in an emb browse seems impossible to enter data (always read only) ??? How can one use it?

    Hi Gaby,

    A field can become unbound when it is placed on a form and then later change the field name in table design.

        Re: System Unbound

        Open any form in design mode, in the DragDrop list, under System you have listed in this order: Date, Unbound, PageNumber, PageXofY, Current_Order, etc... I know what Date, PageNumber, PageXofY, etc... do, but not Unbound.

          Unbound just means that that field, on the form, does not belong to any variable, data field, etc. I would use an Unbound field to store data, as data reference for another form.

          In one system, in a main switchboard menu, I gathered the current user log-in, and other current session information and would store that information in unbound, hidden fields. Almost every form in the system would reference something in that menu.

          Another use, in Access, was to create a combo-box, used a data selection criteria for something else going on in the form. I didn't need to keep the combo-box selection, but reference it, so an unbound field was useful - but in A5 you're only allowed a character type-in field.

          I was able to drop an unbound field on a form, and into a browse, and both were editable.

            strange because I drag&dropped an unbound field in an emb browse and could not enter any data in it: 1st) when I type a text in it the font is tiny, 2nd) as soon as I exit/move to another field the value disappears.

              try it again as it seems to work here....I placed an Unbound field (which is character BTW) onto a form and then on a button's OnPush I put this script--
              if topparent:Unbound.text = "Here"
                  topparent:Unbound.text ="There"
                elseif topparent:Unbound.text ="There"
                  topparent:Unbound.text ="Everywhere"
                elseif topparent:Unbound.text ="Everywhere"
                  topparent:Unbound.text = "Here"
                  topparent:Unbound.text = "Here"
              end if
              Notice I used the .text and not the .value which had problems.

              I was also able to place text into the field and leave it...upon closing and reopening the form it would disappear so it does seem to be a local variable only type field....but so long as the form remained open, the value persisted.

              I have not found any documentation yet on this--it may be in with the What's New documents---most likely in the version 8 if it is as v8 also has this Unbound system field.

                Hi Mike:
                I agree with you that it works when placed on a form. However try to place it in an emb browse and let me know. It seems to me that placed on a form it behaves like a variable, so could not see a real advantage to it. However, If I can get it to work in an embedded browse it would be fantastic. When I place a variable in an emb browse and enter a value in it, the same value appears in every row. If an unbound field in an emb browse can hold temporary text like a regular field it could be very useful.

                  Re: System Unbound

                  Gaby... I should have looked further. In an embeded browse an unbound field is completely unstable. Font is not what is chosen - always the same small font - looks like 6pt. Text disappears on one line and appears on another when you click into a different line. Scrolling through columns, the rows you changed for the unbound column act odd - with data disappearing from columns other than the unbound column. It's like the unbound field just doesn't know what do to.

                    Hi David:
                    Thanks for confirming. Too bad that unbound field does not work in emb browse; it could be very handy.

                      I find the same issues as you in a browse--no clue as to what good this field is for us.
