## What it does
|
|
### VBA Code Description
|
|
#### Overview
|
|
This is a VBA (Visual Basic for Applications) code snippet that is triggered when the `Form_Load` event occurs. The purpose of this code is to ensure that a specific form, "DS PressBrake," remains open on a database application.
|
|
|
|
#### Key Functionality
|
|
|
|
* **Error Handling**: The code uses `Option Compare Database` to specify database order for string comparisons, which ensures consistent case-insensitive comparisons across the application.
|
|
* **Part Number Validation**: Upon form load, it checks if the `PartNumber` field is null. If it is, the subroutine ends, indicating that the required information is missing and preventing any potential errors or unexpected behavior.
|
|
|
|
#### Detailed Breakdown
|
|
|
|
1. **Private Sub Form_Load()**:
|
|
* This line specifies a private subroutine named `Form_Load`. In VBA, this event is triggered when a form is loaded into an application.
|
|
2. **On Error GoTo die**:
|
|
* This statement sets the error handling strategy to stop execution at the first occurrence of an error and jump to the label `die`.
|
|
3. **If IsNull(Me![PartNumber]) Then**:
|
|
* Within the form load event, this conditional statement checks whether the value associated with the control "PartNumber" in the current object (usually a form) is null.
|
|
4. **End**:
|
|
* If `Me.PartNumber` is null, the subroutine terminates immediately using the `End` keyword.
|
|
5. **HelpMe:**
|
|
* This line resumes execution from the label `HelpMe`.
|
|
6. **DoCmd.SelectObject A_FORM, "DS PressBrake"**:
|
|
* The `DoCmd.SelectObject` method is used to select an object with a specified name or ID in a database application.
|
|
* Here, it selects and opens a form named "DS PressBrake."
|
|
7. **DoCmd.Close**:
|
|
* After selecting the desired form, this line closes the currently active form, allowing the selected form ("DS PressBrake") to take its place.
|
|
8. **Exit Sub**:
|
|
* The subroutine exits without performing any additional actions after successfully opening and closing the required form.
|
|
|
|
#### Error Handling Flow
|
|
The code handles errors in two steps:
|
|
|
|
* If an error occurs during the execution of the `Form_Load` event, the VBA interpreter stops at the first occurrence of the error (`die`) and then jumps to the error-handling routine (`HelpMe`).
|
|
* The `HelpMe:` label is where any necessary recovery or cleanup actions should be placed. In this example, it simply resumes execution from that point, which in turn leads back to opening the desired form.
|
|
* If the required information (in this case, a valid part number) is missing, the program ends prematurely.
|
|
|
|
#### Summary
|
|
This VBA code ensures that when its associated form loads, if necessary information (like `PartNumber`) is missing, it opens an alternative form named "DS PressBrake" to address the issue. The code uses error handling and validation checks to minimize potential problems caused by uncomplete data in the database application.
