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 delete a record in the same time

    Hi all Alpha expert,

    I have the set structure same as the Alpha sport.
    I have g1invoice header table (parent) and g1invoice items(chile)
    I created a button to delete a record from main form (g1invoice header)
    When I delete a invoice (invoice number = 009) it can delete a record of invoice number 009 in g1invoice header table only but all invoice items of invoice number 009 in g1invoice items table still exits. How can I delete all record of invoice number 009 both from g1invoice header table and g1invoice items with single button.


    Re: How to delete a record in the same time

    I can find and do it now. Just add button, script Genie and select Parent level to delete.
    after I press button to delete the record I found sometime it can delete the data in g1invoice items and sometime it cannot.

      In the set structure you need to turn on allow cascading deletes etc in the join

        Write a delete operation for the child table(s) and use scripting to filter the records that you want.

        Using the cascading deletes works on a limited number of records, but as the number of records grow, there is too much locking - causing limits to be exceeded and performance issues..

          Mark, Al,

          Do you have any sample code or script?
          In each invoice header has 1-3 records of goods items?
          Now I have to use button 2 places. First to delete the all items one by one in embbed browse (invoice items) and then I have to use button to delete the blank invoice of invoice header.

          Thank you for advise


            Re: How to delete a record in the same time

            This will delete the line items and the header record of the currently visible record on the AlphaSports invoice form.

            a_tbl = table.current(3)
            a_tbl.delete_range("Invoice_Number = "+quote([COLOR="Red"]invoice[/COLOR].value))
            b_tbl = table.current(1)
            b_tbl.delete_range("Invoice_Number = "+quote([COLOR="red"]invoice[/COLOR].value))
            Change invoice to the object name of the invoice_number field on the form. I have seen that field named "invoice2" in some AlphaSports versions.
            There can be only one.


              Re: How to delete a record in the same time


              Thank you for the sample code.
