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.

    Retrieving field data from another file to the cur

    I have a form over the parent of a set that optionally needs to obtain two fields from one of two different master files (not in the set) and put the fields into the parent form and database. The parent form has a selection button for each master form. Each master file has a special selection form for this purpose. I have created two global variables to contain the two fields that are the same format and length in either master and the parent form. When I execute either choice I get the correct master and can select the proper record but nothing in the varibles or back to the parent form. Any suggestions?

    Hello Lloyd,

    ""When I execute either choice I get the correct master and can select the proper record but nothing in the varibles or back to the parent form. Any suggestions? ""

    It sounds like you have the structures in place, but you will have to explicitly tell Alpha to put the, in your words, "Master table" field value in the variable, then explicitly tell Alpha to put the value of the variable in the specific parentform field.

      That wasn't very good was it...... sorry, hit the send button before thinking.

      Check out the Action Scripting commands for setting variable values, and setting field values. This will allow you to explicitly perform the actions I mentioned above.

        RE: Retrieving field data from another file to the

        Thanks for the speedy reply: Here are the Action Scripts I used:
        Going out to the master from the parent form I execute the following:
        1. DIM to define the variables � to insure that the variables are available
        2. Get Field Values (into Variables) � to load the parent form values
        3. Open Form or Browse Layout � Opens the proper form to the selected Master file
        4. Set Field Values � sets one parent form value upon return
        5. Set Field Values - sets other parent form value upon return

        In the master there is a select button that
        1. Set variable to constant or expression result � sets one variable to the selected record field value
        2. Set variable to constant or expression result - sets other variable to the selected record field value
        Exiting this form only closes the form

        In the parent form I have even tried a button to update although I can see no reason to have it as there is nothing in the fields upon return
        1. DIM variables � same two global variables
        2. Activate a Form/Browse Window � to reactivate the parent form
        3. Set Field values � to set the form field values and therefore the database
        4. Refresh the Display � to refresh the parent form just in case it doesn�t display without it.

        This does not get the information to the parent form.
        I have tried various other groupings of the action scripts with no positive results. Again thanks.
        Lloyd

          Lloyd,

          It almost sounds to me like you're trying to replicate the functionality of the existing table lookup field rules. They can easily be used to lookup field values from tables external to the current set. In fact, they work best that way. -- tom

            I agree but have two masters and have found no way to select which file the field rules will display and return. Did I miss something in doing field rules? I will try it again and see if there is an option not seen before.

              I tried this and there really are two or more files to select based on a code in the parent form but still nothing was returned. Thanks anyway.

                RE: Retrieving field data from another file to the

                The source table for the lookup can be defined conditionally. If there's a field value in the record being edited, the field rule can use it to decide which source table to pull records from...
