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.

    Go to record problem with numeric field

    Hey all,

    I have a db that keeps track of our Equipment inventory and the maintenance history. I assigned each piece of equipment an ID# but originally let it be a character field. I have a form that sorts the equipment by type and when you want more detail about a certain item you can push button for more info. and you get another form. That setup has worked great. I've recently tried changing the ID# from c to n so that I can easily keep the list in numeric order. However, when I change to numeric, it gives me an error about line 11 and having an empty expression. When I change back to c, the button works great. So, it's something about changing to numeric that is giving me the error.

    I'm trying to better understand the code that I basically copied from Alpha Sports to zoom, and I would like to know what I need to change in the following code in order for me to keep the LabID field numeric.

    dim t as p
    t = table.current()
    dim count1 as n
    'count1 stores the number of line_items for the current invoice before we zoom to the "Items" form.
    'this will allow us to determine if the user added new lineitems after returning from the Zoom.
    count1 = t.eval(equip_inventory->Lab_Id)

    Thanks for any input and suggestions,
    Rookie

    Re: Go to record problem with numeric field

    I don't see an issue with what you have posted.

    My test.

    Code:
    tbl = table.open("allen")
? tbl.eval("allen->descr")
= "HAMBURGER HELPER LASAGNA                 "

? tbl.eval("allen->sold")
= 4.000000

tbl.close()
    is there more to the script?


    I've recently tried changing the ID# from c to n so that I can easily keep the list in numeric order.
    Have you ever used SORTSUBSTR( Input_String as C, Delimiter as C [, Direction as C [, Type as C ]] ) with the optional Type parameter which sorts character strings as if they were numeric?

    Code:
    numberstring = <<%str%
#12
#23
#123
#45
#456
#16
#56
#%str%

? numberstring
= 12
23
123
45
456
16
56


? sortsubstr(numberstring,crlf(),"A","N")
= 12
16
23
45
56
123
456
    There can be only one.
