Key Takeaways
The video explains how to automate data entry in Microsoft Access using macros. Specifically, it details the process of creating a macro that automatically populates the state and country fields and moves the cursor to the zip code field when "Seattle" is entered into the city field.
The video demonstrates how to attach this macro to the "On Exit" event of the city field and utilizes the "Set Value" and "Go To Control" macro actions to achieve this automation. This method aims to save time and reduce data entry errors by linking field values.

Quiz Answer Key
The primary benefit of using macros to automatically populate fields is to save time and decrease data entry mistakes by setting the value of one field based on the value entered in another field. This automation reduces the need for manual input of related information.
The four event properties mentioned are "On Enter" (macro executes when the cursor arrives on the control), "Before Update" (macro executes before the control's data is updated), "After Update" (macro executes after the modified control data is updated), and "On Exit" (macro executes when leaving the control).
The "On Exit" event property is used in the example. This event is chosen so that the macro executes after the user has finished typing in the "City" field and moves to another control, ensuring the city value has been entered before the automation occurs.
The two macro actions are "Set Value" and "Go To Control." "Set Value" automatically enters a specified value into a designated field (used for "State/Province" and "Country/Region"). "Go To Control" moves the cursor or insertion point to a specified field (used for "Zip/Postal Code").
The "IF" statement within the macro checks if the value entered in the "City" field is equal to "Seattle." Only if this condition is true will the subsequent macro actions (setting the state and country and moving the cursor) be executed.
To access the Macro Builder, first select the desired control (e.g., the "City" field) in the Design View of the form. Then, in the Property Sheet panel, navigate to the "Event" tab, find the desired event property (e.g., "On Exit"), and click the "Build" button (the three dots) next to it. Finally, select "Macro Builder" in the "Choose Builder" window and click "OK."
The "Set Value" macro action automatically enters a predefined value into a specified field. In the example, it is used to set the "State/Province" field to "WA" and the "Country/Region" field to "USA" when the "City" field contains "Seattle." This action requires specifying the "Item" (the field to be set) and the "Expression" (the value to set).
The "Go To Control" macro action moves the cursor from the current control to a specified control. In the example, after automatically populating the "State/Province" and "Country/Region" fields, this action moves the cursor to the "Zip/Postal Code" field, streamlining the data entry process for the user.
Clicking the "Show all actions" button in the Macro Builder window ensures that all available macro actions are displayed in the "Add New Action" dropdown list. Some actions are hidden by default, so this step guarantees that the user can find and select the "Set Value" action, which might not be visible otherwise.
To test the macro, switch the form from Design View to Form View, navigate to a new record, and enter "Seattle" in the "City" field. Then, press the Tab key to move to the next field. If the macro is working correctly, the "State/Province" field should automatically populate with "WA," the "Country/Region" field with "USA," and the cursor should move to the "Zip/Postal Code" field.
Glossary of Key Terms
Macro: A series of actions that you can run to automate tasks, especially repetitive ones, in Microsoft Access.
Data Entry: The process of inputting information or data into a database or form.
Form: A database object that you can use to enter, edit, or display data from a table or query.
Control: An object on a form or report that you use to display data, perform actions, and make the user interface easier to work with (e.g., text boxes, combo boxes).
Event Property: A setting that determines how a control or form responds to various occurrences (events) such as the cursor entering or leaving a field, or data being updated.
On Enter: An event that occurs when the cursor moves into a specific control.
Before Update: An event that occurs before data in a control is saved to the underlying record.
After Update: An event that occurs after data in a control has been saved to the underlying record.
On Exit: An event that occurs when the cursor moves out of a specific control.
Macro Action: A single, named task that can be performed within a macro (e.g., Set Value, Go To Control).
Set Value: A macro action that enters a specified value into a field.
Go To Control: A macro action that moves the focus to a specific control on a form.
Design View: A view in Access where you can modify the structure and properties of database objects like forms and tables.
Form View: A view in Access where you can enter, edit, and display data using a form.
Property Sheet: A window in Access that displays the various properties of a selected object, such as a control or form.
Macro Builder: The Access tool used to create and modify macros.
Conditional Expression: A logical statement that evaluates to either true or false, used in macros to control which actions are executed (e.g., an "IF" statement).
