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.

Conditional Field Rule

  • Conditional Field Rule


    I know there is a function avail, but cannot remember where. Even though I dislike field rules, they would work well for me in one application.

    Essentially, I would like to do is place a conditional to execute a field rule that is tied to a particular form.

    For example, if the viewed form is "Invoice Issue" then the conditional rule would subtract, etc.

    Else if the viewed for us "Invoice Return" then the condition would just be an add back to stock

    Has anyone used conditionals like this in Alpha9 ?

    You probably want to code one of the events for your forms (or an object thereon). Code would be specific to the form being viewed.
    There can be only one.

      So that would mean that the field rule in this instance would be Qty_In_Sto that would be in the product table would relate to the form object, in this case "Qty" form the invoice issue. Let me try that. Thanks

        I'm having problems in the field rule conditional, as it only allows for me to select the conditional values for that set. How would the format look for a conditional on the field rule for the Invoice Items Qty:

        Would it be "formview(invoice_Issue)" ...the name of the current object that is loaded for the conditional to fire on?

          Re: Conditional Field Rule

          I'm lost as to what you mean.

          I was thinking of coding, say the onchange event, for a form field object.

          On the "Invoice Issue" form you would replace the current value in the Qty_In_Sto field with its current value - the form field value.

          On the "Invoice Return" form you would replace the current value in the Qty_In_Sto field with its current value + the form field value.

          No field rule involved.

          If you already have a field rule in place and are trying to "conditionalize" it, we'll have to look at it a different way.

            Re: Conditional Field Rule

            Ok, then maybe that is where I should try.

            I was trying the field rule directly from the Product table to execute conditionally. However, even passing a global to the table so it knows in the same table(Product) to add Qty or subtract Qty based upon that that field rule condition.

            Unfortunately, the database does not seem to like a field rule tied to a global variable, so the conditional is bypassed and I just get a field rule error. I've attached the screen and the Field Rule...

              Tell us more about what you are doing.

              Apparently you are working on some variation/modification of AlphaSports. You are adding a returns form that mirrors the invoice form functionality? If you manipulate the sign of the quantity of the returned item the current field rule will suffice (subtracting a minus is a plus).

                Thanks Stan, that is exactly what I'm attempting to do. In fact all I need to do is set now is the initial entry qty field value to a minus, and that should do it.

                Simple enough..
