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.

    stopped working

    The code below is designed to remove the previos year and store for retrieval when necessary. It has worked for years 1995 thru 2001, but only writes a file (500 bytes or so) now.

    BTW, the adding of Y to the beginning of the year name seems to suit Alpha better than when the db name begins with a number.

    a_tbl = table.open("dues.dbf")
    new_name = "y"+alltrim(str(year(date()-365)))
    query.order = "lastname+firs_nam+midinit"
    query.filter = "substr(datepaid,9,2)=substr(new_name,3,2)"
    a_tbl.query_create()
    copy.set = ""
    copy.db = "c:\program files\a5v4\union"+chr(92)+new_name+".dbf"
    copy.dd = .t.
    copy.delete_o_dd = .f.
    copy.records = .t.
    copy.fields = 10
    copy.field1 = "lastname"
    copy.field2 = "datepaid"
    copy.field3 = "duespaid"
    copy.field4 = "assesspaid"
    copy.field5 = "percent"
    copy.field6 = "trade"
    copy.field7 = "dues"
    copy.field8 = "firs_nam"
    copy.field9 = "midinit" '20
    copy.field10 = "dept_num"
    a_tbl.copy()
    file_add_to_db("c:\program files\a5v4\union"+chr(92)+new_name+".dbf")
    query.order = "lastname+firs_nam+midinit"
    a_tbl.close()
    a_tbl.open("dues")
    a_tbl.delete_range("substr(dtoc(date()-365),7,4)"=substr(duespaid,7,4)")
    a_tbl.close()
    a_tbl=table.open(alltrim(new_name)+".dbf")
    a_tbl.index_create_begin("lstfstmid","lastname+firs_nam+midinit")
    index1=a_tbl.index_create_end()
    ui_msg_box("Index","Index has been created.")
    'a_tbl.index_get("lstfstmid")
    a_tbl.index_primary_put("lstfstmid")
    a_tbl.close()
    end

    Is there a way to improve this or should a different approach be developed? Since this has been used 7 times satisfactorally I see no reason for it to quit now.

    All help will be greatly appreciated,

    RE: stopped working

    You should have had problems before now.

    I think the logic of

    query.filter = "substr(datepaid,9,2)=substr(new_name,3,2)"

    may be faulty....


    new_name = "y"+alltrim(str(year(date()-365)))

    ? new_name
    = "y2003"

    ? substr(new_name,3,2)
    = "00"

    ? substr(new_name,4,2)
    = "03" "------------- isn't this what you're really after?


    "the adding of Y to the beginning of the year name seems to suit Alpha better than when the db name begins with a number." - per the documentation.....

    Table and Field Names

    Alpha Five recommends that table and field names start with a letter (A-Z or a-z) and ....

    could explain why.
    There can be only one.

      The table and field names quote is from the version 5 documentation, I don't have the version 4 files with me. I think the same advice was in them. - But I could be wrong, again.
      There can be only one.

        Hi Stan,

        Thank you, I spotted the 3 in lieu of 4 also. I changed it but it did not help.

        Thanks again,

          Ed,

          you use the same pointer (a_tbl) to reference two instances of the dues table and one instance of the newly created table. This is fraught with peril and should never be done. Do not "re-use" pointers inside a script.

          Are you assuming the delete_range sequence and the index creation sequence will occur AFTER the copy sequence is complete? If so, that's dangerous. Scripts are processed asynchronously. The script keeps running after the copy operation is begun. The script does not automatically stop and wait until the copy op is finished.

          I suggest you break the script down into 3 separate scripts and test each separately. Then use the techniques others have described for forcing the combined script to pause at the appropriate times.

          -- tom

            Also, this line:

            a_tbl.open("dues")

            is incorrect syntax.


            S/B

            a_tbl = table.open("Dues.dbf")

            as appears in earlier sequences in the script.

            -- t

              Oops, just another of my many slip-ups.

                Hi Forum,

                It has bothered me for a bit about line four above "query.filter = "substr(datepaid,9,2)=substr(new_name,3,2)" that worked well for a bit but was pointed out to me that it should have read "query.filter = "substr(datepaid,9,2)=substr(new_name,4,2)", which is a significant error. As it turned out that the 3 to a 4 was only necessary after the turn of the century. At least I now know that I was not imagining what I wanted to be true.

                I still extend thanks to all that helped me over the problem.
                Thank you all again,
                Ed
