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.

    fetch find on multiple fields

    I'm doing a lookup in a child table. I created an index for the table that is based on 2 numeric columns.

    My line of code for the fetch_find is this:
    n = tf.fetch_find(tm.Recid+val(right(vSearchText,1)))

    In this syntax the 2 fields are being added together. e.g. If recid = 339 and the result of the 2nd value is 6, the expression results to 345, which will not return the correct record in the child table. What's the proper syntax for this expression to get the lookup to work correctly given that the 2 columns that the index is based on are numeric? Is there something else I can use other than "+"?

    Thanks,
    Bob A.

    I suppose you could base your index on the concatenated string equivalents of the two fields. Remember to trim leading blanks returned by the STR() function.

      Re: fetch find on multiple fields

      That's one of the reasons that fields designed to hold digits shouldn't be numeric unless you intend to use them in some computation.

      Try adding an index tag with the expression

      str(recid)+str(thatotherfield)

      Place that index in effect and use


      tf.fetch_find(str(tm.Recid)+right(vSearchText,1))
      There can be only one.
