## 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

```vb
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

```vb
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.
