1. DB Implementation: MS Access Macros

2. Programming in MS Access
Modules
An organized collection of Visual Basic for Application (VBA) code
More flexible and powerful than macros, but less secure
Macros
A named set of actions that perform operations/tasks
e.g. open/close a form, print a report, set value of a control
Tool to automate tasks and extend functionalities without programming
Macro actions/functions = subset of commands available in VBA
Embedded Macro vs Standalone Macro
Command Button Wizard (embedded macro)
To perform Common Tasks
Macro Builder (standalone macro)
Create/Modify Macros.
Build a list of actions to perform by selecting from list of actions
Database Design

3. Access Macros: Macro Builder
Creating a standalone macro using a macro builder
(Tab) Create → (Group) Macros & Code → click Macro
Select an action from the dropdown menu (e.g., Openform)
creation: CUSTOMER table
multi-table query:
PRODUCT+SUPPLIER
qrySensless, qrySensible
Database Design

4. Access Macros: Macro Builder
Select the form name to open.
Click “Save” icon and enter a macro name.
creation: CUSTOMER table
multi-table query:
PRODUCT+SUPPLIER
qrySensless, qrySensible
Database Design

5. Access Macros: Macro Builder
Click “Run” icon to test the macro.
Select the saved macro name for the “On Click” event of the command button.
creation: CUSTOMER table
multi-table query:
PRODUCT+SUPPLIER
qrySensless, qrySensible
Database Design

6. Access Macros: Macro Builder
Creating an embedded macro using a macro builder
Click “…” icon for an event of the command button & select “Macro Builder”
Follow the same procedure as a standalone macro.
creation: CUSTOMER table
multi-table query:
PRODUCT+SUPPLIER
qrySensless, qrySensible
Database Design

7. Access Macros: Elements
Event  Property Sheet
The reason the macro “fires” or runs.
i.e., the trigger for a macro execution
e.g., a form control gaining/losing focus, mouse click/movement
Action  Macro Builder
What the macro does
e.g. load/close/delete object, set field/control value
Action Arguments (properties)
What action applies to
e.g. frmEmployee
Conditions (i.e., If)
Conditions that must be true for the macro to run
e.g. IsNull(Forms![frmEmployee]![Status])
creation: CUSTOMER table
multi-table query:
PRODUCT+SUPPLIER
qrySensless, qrySensible
Database Design

8. Access Macros: Events Event is the reason the macro “fires” or runs.
A macro’s execution should be triggered by a specific event
Successful macro use depends on
attaching to appropriate events
good macro design.
Example
After Update vs. Lost Focus event
loss of focus can occur without data entry or edit
for data entry trigger, use “After Update” event
Associating Events and Macros
Set the appropriate Event Property of the control to the name of the macro that will perform desired actions.
