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.

    Deleting multiple browse records

    Hi All

    I have a stock order form that contains a browse with all of the parts details for that order.

    This form is built on a set based on two tables, data_stock_order and data_stock_order_parts, with a one to many connection linked by the order id (field name or_id).

    I'm looking to create a button within the form that deletes all of the parts in the browse.

    I tried using the below code, but it only deletes the highlighted parts record.

    Code:
    topparent:Control_browse1.delete_record()
    Any advise on how to best build this button?

    Re: Deleting multiple browse records

    What happens if you highlight the records you want to delete and then do it?
    Option 2 is to delete the parent and that will take the children with it if you have set Referential Integrity ON.

      Hi Ted

      I can create a button that will delete whatever browse record that is highlighted.

      Other then turning on the Referential Integrity, is there a way to modify the button to delete all related child records?

        I meant selecting the records by hlding down the Up Arrow (Upper Case arrow) and draging the mouse over the records or using down arrow (navigation arrow) to highlight them and then deleting.
        Plan B would be to delete the parent. Is there any reason to keep the parent?

          Re: Deleting multiple browse records

          I'm losing the plot!
          Put a logical field in the table populating the browse - say .t. or .f.
          Default to True
          Put a button on the form which changes the true to false.
          Delete all records where Child ID = Parent ID AND logical field = False.

          So, pushing the button updates all child records for this order and you can then run a delete.
          You will still be left with the parent though.

            FROM THE DOCUMENTATION:
            Note : Do not use <TBL>.DELETE_RANGE()in a multi-user environment where other users may lock records within the range.

              Thanks Mike!

              Your code worked really nicely.

              Sorry for the late reply.

                Re: Deleting multiple browse records

                How do I go through all records (in a loop) of the browse and change a field value

                Journal_frm:browse1.Fetch_First()
                Journal_frm:browse1:row_deleted.value=.t.
                Journal_frm:browse1.Fetch_Next()
                Journal_frm:browse1:row_deleted.value=.t.
                Journal_frm:browse1.Fetch_last()
                Journal_frm:browse1:row_deleted.value=.t.
                Journal_frm:browse1.Refresh_Browse()

                  Re: Deleting multiple browse records

                  row_deleted is a field in the browse?

                  There is no .fetch_eof() method for a browse so you'll have to operate on the table shown in the browse. See Mike's first code section above and modify it with your table names.
                  There can be only one.

                    Stan,
                    What about Fetch_last()

                    Comment


                      #11
                      Re: Deleting multiple browse records

                      .fetch_last moves to the last record in the browse. It can't be used for checking whether you are trying to fetch past the end of the browse.

                      That said, trying to fetch past the end of the browse doesn't throw an error like trying to fetch past the end of a table.

                      Code:
                      parentform.Browse1.activate()
                      parentform:Browse1.fetch_first()
                      for qx = 1 to 100
                      	parentform:Browse1.change_mode()
                      	parentform:Browse1:row_deleted.value=.t.
                      	parentform:Browse1.fetch_next()
                      next qx
                      might be inefficient but should work if you never have more than 100 child records in the browse.

                      You could use A5_GET_RECORDS_IN_QUERY() to count the child records and feed the result to the for loop.
                      There can be only one.

                        Oops,
                        rereading this thread, I see that the first lines in my code are wrong, as I have dimmed the pointer variable as C, and should be P
                        Code:
                        'get the linking field value from the parent table
                        dim tp as[COLOR="#FF0000"] P[/COLOR]

                          Re: Deleting multiple browse records

                          This works on all records in a browse
                          Code:
                          p=obj("browse1")
                          p.Fetch_Last() ' to enable getting the number from the browse row number
                          nrecs=p.Get_Viewport_Row()
                          p.Fetch_First()
                          for i=1 to nrecs 'instead of while fetch_last()
                          	browse1:ledger.value = "SALES"
                          	p.Fetch_Next()  'Fetches the next record.
                          next
                          In the case of the row being deleted I will look at a variation on this.

                            Only issue is, it adds an extra blank row in the browse.
