What it does
VBA Code Description: Form_Load
Event Handler
Overview
This VBA code snippet is an event handler for the Load
event of a form in Microsoft Access. The code is responsible for initializing certain settings and behavior when the form is loaded.
Key Functions:
- Error Handling: The code uses
On Error GoTo die
to catch any errors that occur during execution. If an error occurs, it redirects the control flow to the labeleddie
label. - Null Check: It checks if the
PartNumber
field in the form is null or undefined usingIsNull(Me![PartNumber])
. If it is, the code skips the rest of the subroutine and exits. - Default Form Opening: The code opens a new instance of the "DS MultShear" form using
DoCmd.SelectObject A_FORM, "DS MultShear"
and closes the current active window usingDoCmd.Close
. - Exiting Early: If an error occurs or the
PartNumber
field is null, the code exits early from the subroutine.
Step-by-Step Explanation:
- The code starts by declaring that string comparisons will be performed in database order using
Option Compare Database
. - It then defines a private subroutine called
Form_Load
, which is the event handler for theLoad
event of the form. - Inside the subroutine, it checks if there's an error and, if so, skips to the
die
label. - Next, it checks if the
PartNumber
field in the form is null or undefined. If so, it exits the subroutine usingEnd
. - The code then opens a new instance of the "DS MultShear" form using
DoCmd.SelectObject A_FORM, "DS MultShear"
and closes the current active window usingDoCmd.Close
. - If an error occurs or the
PartNumber
field is null, it skips to thedie
label and resumes execution from there.
Example Use Case:
This code can be used in a Microsoft Access application where you want to ensure that certain actions are performed when a form is loaded. For instance, it might be used in an inventory management system to check if a part number is required before opening the "DS MultShear" form.
Code Improvements Suggestions
- Consider adding more error handling or logging mechanisms to provide better insights into what's causing errors.
- Refactor the code to make it more concise and readable by breaking it down into smaller, more focused subroutines.
- Use meaningful variable names instead of abbreviations like
A_FORM
andMe![PartNumber]
.
