What it does

VBA Code Description

Overview

This VBA code is a part of an Access application and is triggered when the Form_Load event occurs. It checks for specific conditions related to the form's settings and takes corrective actions.

Key Sections

Option Compare Database

This line sets the comparison order for string values in the database.
The Option Compare Database statement tells Access to use its own internal string comparison rules, rather than the default culture-specific rules.
This is done to ensure consistent and accurate comparisons of text data across different regions and cultures.

Sub Form_Load

Private Sub: Indicates that this subroutine is private and can only be accessed within the same module.
Form_Load event: This line specifies that the code is attached to the Form Load event, which is triggered when the form is initialized or opened.
On Error GoTo die: Sets the error handling trap for any exceptions that occur during the execution of this subroutine. If an error occurs, the control jumps to the die: label.

Conditional Checks

Check for Null PartNumber

If IsNull(Me![PartNumber]) Then
   End
End If

This code checks if the form's PartNumber field is null.
If it is null, the subroutine ends immediately using the End statement.

Resume HelpMe

Exit Sub
HelpMe:
    DoCmd.SelectObject A_FORM, "DS Laser"
    DoCmd.Close
Exit Sub
die:
   Resume HelpMe

Default Action: Close and Open DS Laser Form

The Resume HelpMe instruction redirects the program flow to the HelpMe: label.
Inside the HelpMe: block:
- DoCmd.SelectObject A_FORM, "DS Laser": Opens a new instance of the specified form ("DS Laser") in the current database.
- DoCmd.Close: Closes the currently open document (if any).
- The subroutine ends using Exit Sub.

Error Handling: die:

If an error occurs during the execution of this code, it is caught by the die: label.
This instruction simply resumes the normal program flow from where the error occurred.

In summary, this VBA code checks for a null PartNumber field in the form's settings and takes corrective actions. If the PartNumber is null, it ends immediately. Otherwise, it closes any open document and opens a new instance of the "DS Laser" form. The code also includes error handling to ensure that the program continues running smoothly after encountering an exception.
