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.

    Help with UDF

    Hi, I had a problem wherein a case statement I was using in an expression was too long (more than 1024 characters) for a calcullated field in a report. A fellow person on the forum suggested I try stating my case statement in a UDF. I did this. I tested the syntax and all seemed fine. When I called the UDF up in my calculated field. it showed at the bottom that the result was "0" and was numeric. The result should not be zero but should have a price in it. A truncated version of the case statement reads as follows :

    Case(ameregl3->Type_Of_Service="B".AND.Clients->Special=.T..AND.ameregl3->Recv_d_electronically=.T.,Bacitylist->Price+3.00)

    This is just one small portion of the case statement, but it should still read a result of some type of price and not zero. I am calling this UDF up in a calculated field on my billing Invoice (which is actually a report). The records are specified prior to running the report. I am unsure why I am getting a zero instead of a price. Any help would be greatly appreciated. Thanks in advance.

    Re: Help with UDF

    You mention that this code is inside of a UDF. Can you provide the full UDF? If that can't help us provide an answer we will then need to see some sample data that generates the error. Without any of the above information we are unable to provide very much assistance due to lack of details.

      Hi,

      The full text within the UDF is the following:

      'Date Created: 29-Jan-2010 02:39:07 PM
      'Last Updated: 31-Jan-2010 09:01:00 AM

      FUNCTION Prices AS N ( )
      CASE(ameregl3->Type_Of_Service="B".AND.Clients->Special=.T..AND.ameregl3->Recv_d_electronically=.T.,Bacitylist->Price+3.00,ameregl3->Type_Of_Service="B".AND.Clients->Special=.T.,Bacitylist->Price,ameregl3->Type_Of_Service="P".AND.Clients->Special=.T..AND.ameregl3->Recv_d_electronically=.T.,sbcitylist->Price+3.00,ameregl3->Type_Of_Service="S".AND.Clients->Special=.T..AND.ameregl3->Recv_d_electronically=.T.,sbcitylist->Price+3.00,ameregl3->Type_Of_Service="P".AND.Clients->Special=.T.,sbcitylist->Price,ameregl3->Type_Of_Service="S".AND.Clients->Special=.T.,sbcitylist->Price,ameregl3->Type_Of_Service="PO".AND.Clients->Special=.T..AND.ameregl3->Recv_d_electronically=.T.,sbcitylist->Price+3.00,ameregl3->Type_Of_Service="PO".AND.Clients->Special=.T.,sbcitylist->Price,ameregl3->Type_Of_Service="C".AND.Clients->Special=.T..AND.ameregl3->Recv_d_electronically=.T.,Sbcitylist->Price+3.00,ameregl3->Type_Of_Service="U".AND.Clients->Special=.T..AND.ameregl3->Recv_d_electronically=.T.,Bacitylist->Price+3.00,ameregl3->Type_Of_Service="U".AND.Clients->Special=.T.,Bacitylist->Price,ameregl3->Type_Of_Service="C".AND.Clients->Special=.T.,sbcitylist->Price,ameregl3->Type_of_Service="L".AND.Clients->Special=.T.,sbcitylist->Price,ameregl3->Type_of_Service="FE".AND.Clients->Special=.T.,sbcitylist->Price)
      END FUNCTION

      The case statement is supposed to return prices we have charged for tasks according to the different scenarios layed out by the case statement. The case statement itself worked as a calculated field in the report when it was shorter (less than 1024 characters). Unfortunately, it did not cover all the variables required for proper billing. When it was lengthened, that's when I discovered it was too long to use as an expression. That's when it was suggested to me to call it up as a UDF within the calculated field. Thanks for looking at this....it's greatly appreciated.

            Hey Andy,

            Tried your theory out...not sure if it works or not. When I run my report, it gives the same amount for every entry. Each entry would of course be different depending on each of the variables stated in the CASE statement. It doesn't seem to be applying it to each record. Still stumped.
