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.

    array help

    Hi

    I have a invoice form. When fetch each record, I will query this customer have any other invoice overdue. I develop a query and copy the result to array. How to show the array on the form? Any suggestion is appreciated. Thank in advance.

    Here is my query and copy to array on OnFetch event:
    ----------------------------------------------------
    dim tbl as P
    dim qry as P
    dim nrecs as N
    dim c_no as c

    c_no=topparent:CUST_NO.text
    if alltrim(c_no)"""" then
    tbl=table.current()
    query.description = "Keep Last Invoice"
    Query.filter="CUST_NO='"+c_no+"' .and. OVERDUE"=1.0"
    Query.order="SHIP_DATE"
    Query.option=""
    qry = tbl.query_create()

    nrecs = qry.records_get()
    dim i as N
    i=1
    ui_msg_box("test","record: "+str(nrecs),UI_OK)
    IF (nrecs " 0) then
    dim global invoice1[nrecs] as P
    tbl.fetch_first()
    while .not. tbl.fetch_eof()
    invoice1[i].cust_no = tbl.cust_no
    invoice1[i].invoice_no = tbl.invoice_no
    invoice1[i].ship_date = tbl.ship_date
    invoice1[i].overdue = tbl.overdue
    i=i+1
    t.fetch_next()
    end while
    end if
    qry.drop()
    end if

      RE: array help

      If what you want to do is show the query results in the form, then I'm not sure why you are doing the array.

      If, rather than using the table.query_create() method, you run a form-based query such as:

      This:tables:Appoint.filter_expression = this_filter
      This:tables:Appoint.order_expression = "LINK1"
      This:tables:Appoint.query()
      pidx = This:tables:Appoint.index_primary_get()
      recs = pidx.records_get()
      this.resynch()

      In the above example, "this" is the pointer to the form itself because this script is run in the On Init event of a form.

      You can substitute "this" with a formname or a form pointer (such as topparent) if running the query from another location.

      Appoint is the parent table of the set on which the form is based.

      This_filter is the filter from a statement such as:
      this_filter = "CUST_NO='"+c_no+"' .and. OVERDUE=1.0"

      recs returns the number of records found so you can reset the form if no records are found and this.resynch() refreshes the form to show the query results. Again, "this" is a pointer and you need to change it according to the location of the query.

        RE: array help

        sorry I didn't explain well. I need to have the invoice info. and customer infor. and also how many other invoice the custome didn't pay on the "invoice" form. So when I open a invoice form, I need to query the other invoices this custome didn't pay and show it.

        Right now I keep three variables for the oldest invoice the customer didn't pay.

        Is there a way I can track all invoices the customer didn't pay? Thanks.

              I defined array invoices[3]. When I use invoice[i].invoice_no, it has error "invoice not found". But if I use invoice[1].invoice_no, invoice[2].invoice_no,etc.. it works fine. Does any one have any idea? Thank in advance.

                In Help, there is example:
                Dim a[1] as P

                A[1].name = "Fred"
                A[1].city = "Boston"
                A[1].age = 23

                A[].name = "Tom"
                A[..].city = "NY"
                A[..].age = 35

                but when I use A[..], script error: unexpect value.
                Is this in Version 5 or version 6? Thanks

                      Hello Ed,

                      In the examples you linked to, the functions return type is declared as "V". Is this a variant type? I don't find any reference to a "V" type. Also, if this is a variant type, how is this different from "A" type?

                      Thanks,
                      Jim

                        "V" stands for Void.
