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.

Req row number to select records

  • Req row number to select records

    Hi there,

    I have a Form 'Debt_Xact_pay_m' into which I enter a Payment record consisting of an Account id 'Tx_acc_idf' and other data.

    A Save button calls, in addition to others, a Script 'Trde_xact_plug_rows_only'. I attach a screen shot showing the code.

    I include an Index 'td_tx.index_primary_put("Rows_Plug_")'. This index includes an Account Id "WOW001 " and other fields. I attach a screen shot showing the index structure.

    The result is what I am looking for ie. row number to "WOW001 " selected records. I attach a screen shot showing the resulting Browse 'Trde_Xact_awt_alloc_b'.

    This works only if Account Id "WOW001" is selected. There are a few thousand Accounts, so I have a problem of building a few thousand Indexes !!

    I have tried replacing then Account id with a variable 'gdpp_acc_id' in the index "Rows_Plug_" when I define the index, but the problem is that it builds nothing because at the time of index definition the var->gdpp_acc_id is empty. I tried introducing 'td_tx.index_create_begin("Rows_Plug_" ,s_quote(td_tx.Tx_dtef), filt)
    'Row_Crte = td_tx.index_create_end(), but the problem is that the Table 'trade_transactions' is probably being used at that time for Enquiries or whatever.

    Any suggestions on how to get those row number onto the Browse ?

    I trust I have given enough here to explain my problem. If need be I can extract data down to 5Mb and attach the db.

    Looking forward
    Dave Mac

    Dave,

    A brief narrative explaining what you are trying to accomplish would help us help you. You've done a good job telling us what your code does, but havent' told us why. What's the goal?

    Instead of using a filtered index to identify the records to be changed I can think of two other options:

    a) run a query against the target table, and then change the records one at a time; or

    b) order the records in the target table by Tx_acc_idf, then use a custom UDF to fetch the first candidate record and then change it if the found record has the necessary characteristics, then fetch the next record, examine it, and either change or skip, and continue until the Tx_acc_idf field changes or you fetch past eof.

      I think for the variable to work in the index it has to be defined as global and be initiated when the app opens. Then you can change that variable in the OnFetch event of the form or with a script.

        You don't put the variable in the index.

        Use the variable to find the record in the index with code in an event for the form or browse.

        1. set the index
        2. do a fetch find to get the record needed using the variable.
        or
        do a query based on the variable to get the records that have that value in it..

        If you put a variable filter in an index, the index is evaluated with the value of the variable at the time the index is built or reindexed, but doesn't change as the variable changes.

            Way too much to work through... Hopefully someone has the time to look at this..

            Or you need to simplify what you have to focus on one issue at a time..
