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.

    Calculated Field in a Browse

    Hi.... I was having a problem with a "case" statement being too long for an expression within a calculated field. One of you suggested I try calling it up from a UDP. That was a great idea and it worked beautifully. My client now wants the same info in an Excel file. My idea was to append the necessary files to a new table and use a calculated field within the browse to give all the correct prices and then copy everything from the browse to a new table and export those records. Anyway, I was planning on using the same global UDF for the expression within the calculated field. However, when I call up the function in the expression builder, it just flatly states that it is an incomplete expression. Not sure why. I'm calling it up the same way I did in my Invoice. My understanding is that the UDF will call up records from different tables within the set. My table I am using is linked to the set so I'm not sure why it doesn't seem to recognize the function. Again, thanks for any and all help.

    Could you clarify what you mean here?

    Please post the udf script and descripe the context in which it is used when it runs successfully.

      Scott....please at least post the function and then maybe someone could give you an answer....a User Defined Function is just that...something a user created. What it does all depends upon how it is coded. Until we see that code, even with an answer to Tom's query, there will most likely not be a specific answer.

        Re: Calculated Field in a Browse

        Hi everyone.... sorry I had a brain fart. The reason it wouldn't work properly was because I wasn't calling the records up from within the specified set. Once I did that, it worked perfectly. However, I do have an addiitonal question. Is there a way to export a table where one of the fields is a calculated field? I have tried several times and all fields export fine except any info contained in the calculated field. I am assuming that because the calculated field is filled in on the fly, as it were, the info is trully not saved in that field. So, is there a way that the info in the calculated field can be eiter copied to another table, saved and exported or something. I really need the info provided by my calculated field to be included in an export to an Excell file... As always, thx all for all replies.

          You shouldn't have any trouble exporting a calculated field defined in a table. If the calculated field is defined for a browse it is only there when the browse is displayed and thus is not exportable nor is it copyable to another table.

          Just add field to your table, make it calculated, and use the same expression as for your browse.
          There can be only one.

            Many thanks Stan. I will give that a try. I figured there had to be another way to do it. And yes, the calculated field is defined in the default browse and not the table per se. Thanks again!! I don't care what anyone says... I've been using A5 for about 10 years and I still think it's the best relational database out there. Thanks again for everything!!

              Re: Calculated Field in a Browse

              Hey Stan, I tried defining the calculated field in my table but it does not work. I assume because according to field rules, it will not work across different tables within the set. The information to determine the correct pricing is taken from different tables within the set. When I enter the UDF or the Global Calculated field name in the expression builder for the calculated field rule, it just says "Incomplete Expression". I assume this is because it cannot access the information it needs to from all other tables in the set. Is there another way to make a calculated field in a table or am I having another "senior moment"? Thanks again for your reply....

                Since you can't create the necessary calculated field in a table, export the fields necessary to the calculation and perform the calculation in the resulting spreadsheet.

                  Or possbily even add the field to your export table, use the calculated value when in the browse and write it to the field??? All depends upon how you have things set up and such---just know that most things can be done within Alpha....I have done an Excel export of a browse that has the calculated field in it and all exported just fine---I could have just as well looped through the browse and added the value to a table field and then exported the table.

                  Just other thoughts.....
