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.

    Alpha5 does not deal correctly the second level links inside browse. please help..

    OK, this is the situation:
    I have a table with clients, every client can have services, every service can have one invoice.
    So this is the set:
    CLIENTS ==>SERVICES-->INVOICES
    The "==>" stands for one to many link, the "-->" is one to one link.

    Now, in the CLIENTS_FORM I have a browse for the related services. One column of this browse is INVOICE_CODE, a field in the table INVOICES.
    Now, if there is some change done with Xbasic to the value of INVOICE_CODE, alpha5 is unable to resync the new value, the only way to do this is to close the CLIENT_FORM (unlocking the set I think) and open it again.
    I had the same problem in other situations, and I solved with some kind of workaround. Now is harder to find a workaround, can you help me finding a way?
    My need is to refesh the INVOICE_CODE in the browse... without closing and restarting the program :-O
    I tryed different refresh methods (object, browse, display), no one helped.
    It seems the problem is deep in the linking engine of A5, if I try to use a field from INVOICES outside the browse but inside the CLIENTS_FORM i have the same problem.

    Thank to you all for the help you keep on giving!
    Enrico


    EDIT: well, "an Xbasic change to the value of INVOICE_CODE" is not the right sentence.
    Here what's happen:
    When it's created every record from SERVICES is linked to a dummy, hidden invoice, with INVOICE_CODE value "No One"
    When invoice is emitted, the related service is linked to the right invoice, usin Xbasic, with INVOICE_CODE value "2013 - 24"(just an example)
    In the browse, the colum INVOICE_CODE is stuck to "No One". No refresh works, the best I can get is that the value of INVOICE_CODE simply disappears.
    If I close the app and run it again the INVOICE_CODE correctly diplays "2013 - 24"

    Thanks again.

    Are you sure you are thinking this correctly. Usually the pattern is that an invoice is for one client having services and the parent is invoice is parent 1:1 with client 1:1 or 1:M with service.

      I tryed different refresh methods (object, browse, display), no one helped.
      But did you try the resynch method?

      The <OBJECT>.RESYNCH() method does a new query, re-fetches all data for the form or browse, and then repaints it.
      There can be only one.

        @ Stan: you scored, that was my fault. I apologize for my ignorance, but I'm from another RAD where every relation is automatically synched every time a related data is needed.
        Indeed, it sounds weird that sometimes I have to explicitly resynch with a command... very weird. I'm a six month old user of A5, but I have alredy had the sensation that the relational database engine is somehow weak. And when it's not smart enough, you have to change your way doing, or you have to place a little push, like this resynch.
        Anyway, really thanks for the tip.

        @Mike: yes, you are right, but basically your situation is the same as mine: I just reversed the invoice==>services, because the program needs to show the active service as main data associated with clients, and the related invoice is an additional information.
        Schematically:
        Data structure:
        CLIENTS==>INVOICES==>SERVICES
        CLIENTS==>SERVICES
        Data Rapresentation structure:
        CLIENTS==>SERVICES-->INVOICES
        well... it works :)
