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.

    Thank you Cal. Seems clear enough.

    Re: Error Trapping?

    I think the answer to your question is yes. (I'm just not absolutely positive about what you are asking.)

    Here's a simple example of something I use in one of my apps. My error routine saves the errors to a text file and also allows the user to e-mail them to me.
    Code:
    FUNCTION MyFunction as C ()
   ON ERROR goto Error_trap
   ...
   [The rest of the code here]
   ...
   EXIT FUNCTION
   '---------------
   Error_trap:
   '---------------
   e_resl = script_play("AimsErrorHandler")

END FUNCTION
    My "AimsErrorHandler" could just as easily have been a function. In fact, if I were doing it today, it probably would be.

    Second part, no, but you can

    Code:
    on error goto error_handler
for x = 1 TO 10
    if (x = 3) then
        stop
    end if
    trace.writeln(str(x))
next x
trace.writeln("End")
end
error_handler:
    [COLOR="Red"]my_error_function() [/COLOR]
    resume next
    Just reviewed your code again and it appears that you really just need to enable your error code in each script/function? You can create one function that will handle all the errors?

    Re: Error Trapping?

    Does this mean that if you are writing a function, the "goto label" is included in each function that you write?

    Any better documentation that you've seen on error reporting?

    I know we all write perfect code so errors just shouldn't happen, but the inability to write an overall error handler is a real bummer.

    Error Trapping?

    Newbie question.

    Can you establish one ON ERROR GOTO command to trap errors throughout the application or do you have to include a separate one for each script/function? I've read through the help file and unfortunately, I could ascertain a clear designation.

    Secondly, can the "goto label" be a separate script that handles all the error trapping and logging?
