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.

    Trouble with a set

    I have just create a set with :
    ' Xbasic script for create a set
    '
    child="z01_vga"
    setable="z02_vga"
    parent1="ZONA"
    parentk1="Idzona"
    childk1="IDZONA"
    child3="AGENTE"
    parentk3="AGENTE"
    childk3="IDAGENTE"

    child1=child+"_" + str(year(date())-1,4,0)
    child2=child+"_" + str(year(date()),4,0)

    nameset=filename_decode(setable+".set")

    parent = table.open(parent1)
    child_tbl = table.open(child1,FILE_RW_EXCLUSIVE,"year1")
    table.index_create_begin("MAIN", childk1)
    index1=child_tbl.index_create_end()
    relation.link_type = LINK_MANY
    child_index = child_tbl.index_get("MAIN")
    relation.index_child = child_index
    relation.order_parent = parentk1
    relation.ref_integrity = 0
    parent.relation_add(child_tbl)

    level2 = table.open(child3)
    table.index_create_begin("MAIN", childk3)
    index1=level2.index_create_end()
    relation.link_type = LINK_FIRST
    child_index = level2.index_get("MAIN")
    relation.index_child = child_index
    relation.order_parent = parentk3
    relation.ref_integrity = 0
    child_tbl.relation_add(level2)

    child_tbl = table.open(child2,FILE_RW_EXCLUSIVE,"year2")
    table.index_create_begin("MAIN", childk1)
    index1=child_tbl.index_create_end()
    relation.link_type = LINK_MANY
    child_index = child_tbl.index_get("MAIN")
    relation.index_child = child_index
    relation.order_parent = parentk1
    relation.ref_integrity = 0
    parent.relation_add(child_tbl)

    level3 = table.open(child3)
    table.index_create_begin("MAIN", childk3)
    index1=level3.index_create_end()
    relation.link_type = LINK_FIRST
    child_index = level3.index_get("MAIN")
    relation.index_child = child_index
    relation.order_parent = parentk3
    relation.ref_integrity = 0
    child_tbl.relation_add(level3)

    parent.set_create(nameset)


    level3.close()
    level2.close()
    child_tbl.close()
    parent.close()
    file_add_to_db(nameset)

    after execution of the script in the control-panel I see the new created set but when I try to open it the Alpha message 'Could not find set '...' appear. The set is on correct location and the button "Design -> Table in set" show the right tables.
    Please help me...
    P.S. I'am Italiano of Napoli, sorry for my english. There are italian developer in our excellent Alpha 5 ?

    RE: Trouble with a set

    Pasquale,

    If you want some help with this, you will need to break it up into paragraphs, etc. Your requst is difficult to understand when it's all run together. Make it easier to read.

      Pasquale,

      I presume most of the entire post is xbasic to open ????Tell us what are you trying to do? What do you wnat to do? If it's what I think, there are much easier ways than this.

        RE: Trouble with a set

        I have just create a set with the istruction in the attachement.
        After the execution of the script, in the control-panel I see the new created set but when I try to open it the Alpha message 'Could not find set '...' appear. The set is in the correct location and the button "Design -> Table in set" show the right tables. I need to use the Xbasic script because it is part of a procedure to import ascii data in a Alpha database.
        Please help me...

          Pasquale,

          "I have just create a set with the istruction in the attachment." I don't know what you mean by this. When you created the set, did you use the xbasic code as an expression to create the link between 2 or more tables?

          I'm not the expert here but I wouldn't do it that way. Have you looked at Alpha's import opreation found in the Operations tab of the Control Panel? If at all possible, I would open a form based on the set and then click on a button which performs the import operation. Another way is to put the import operation on the OnInit event of the form so that when the form opens, the import operation automatically run.

          This are my thoughts and perhaps others with experience in imports can offer better advice.

            RE: Trouble with a set

            kenn,
            ok. i am not sure, but the set is created succesfull when the statement :
            child_tbl = table.open(child1,FILE_RW_SHARE,"year1")
            used for assign a 'alias' for a child table, is substitute with :
            child_tbl = table.open(child1).
            This is not a solution for me, but i have resolved my problem in another way.
            Thank for your attention.

              Pasquale,

              Your a man of great talent. However, I'm confused about the way you desrcibe the creation of a set. The set is created w/o using Xbasic but Xbasic can be used in an expression to create the links between tables. I presume thsi is what you mean.
