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.

    save Last value edited (Desktop app)

    How do i make the last value edited to be saved on a new field of the same table? e.g. in an item maintenance form of a product table, there is a price and a user field,i want to save the last value of the price on another field, the same with the user who edited the price or any other field on the same table.How do i do this in alpha?this is for sucurity purposes in the app. maybe it could be done using the audit trail feature of alpha but, i want it to be displayed immediately on the form after a new record is added or after a new record is added or changed on any table.

    tblProduct= product table

    Barcode
    ProductName
    RetailPrice
    LastUser = last user who edited the price or any other field
    Lastedited = date and time edited or added
    LastPrice = value of price prior to edit

    Sampe Data
    012345 - bcode
    Milk - product name
    250 -Price
    John - last user who edited the table items
    02-01-2012
    240 - last price

    User Jet has logged in and changes the price to 260

    New Data saved
    012345
    Milk
    260
    Jet
    02-03-2012 - date last edited
    250 - new last price prior to editing

    .How about if a new record is added? for the user who last edited field,How do i get the user currently logged in to be default
    on the new record/item added? for the date last edited field, it would be easy as i will just make a field rule to default as the current date, same
    with the last price, the default would be zero.Please help, i'm still learning alpha, and i tried but i'm stucked/struggling for 2 days to find the solution but im stucked.thank you.

    You use the table field rules, Events tab, Cansaverecord event. You code that event to save any values to any fields you want in any table you want. Doesn't make any difference whether it is a record change or a new record.

    Please help, i'm still learning alpha, and i tried but i'm stucked/struggling for 2 days to find the solution but im stucked.thank you.
    Possibly if you spent some time becoming familiar with the documentation then searching for things wouldn't be so difficult.
    There can be only one.

        Jet,

        To most database folks the "last record" means the last record in the table, or possibly the last record in a queried subset of the table. This is very different from the "previous record". I suspect that you are really talking about a "previous" field value, rather than the "last" field value, right?

          Yap Tom, It is like an audit trail, wherein the last price will be saved after the edited is saved with a new one. I just want to display on the form so that users who last edited will be visible.

            place this code into the CanWriteField field rule for the retailprice field (this assumes the table is a single table or a parent table in a set). You will see the change when the record is saved. Do the same with the other fields.

            Code:
            dim t as p
t=table.current()
t.lastprice=t.retailprice

              Once again MIKE, i appreciate how you reply to questions with actual code. Thank you thank you thank you, great help to directly answer my question but i believe alpha five has documented all, it is just a matter of searching the Wiki. With all due respect to Stan, Tom, Ted, Keith and others I also appreciate your help. Nice to see things(Code) in alpha doing well
