## What it does
|
|
**VBA Code Description**
|
|
==========================
|
|
|
|
### Overview
|
|
|
|
This VBA code is designed to run on a regular interval (via the `Form_Timer` event) and performs several tasks related to database management and form interaction.
|
|
|
|
### Key Components
|
|
|
|
#### 1. Error Handling
|
|
|
|
The code uses an error handling mechanism (`On Error GoTo Err_Button0_Click`) to catch any errors that may occur during execution. If an error is encountered, a message box will display the error message (`MsgBox Error$`), and the code will attempt to continue executing from the `Exit_Button0_Click` label.
|
|
|
|
#### 2. Form Timer Event
|
|
|
|
The code leverages the `Form_Timer` event, which is triggered at regular intervals (in this case, it's not specified how often, but it's likely set to a specific time interval). This allows the code to run repeatedly without requiring manual intervention.
|
|
|
|
#### 3. Database Interaction
|
|
|
|
The code performs several database interactions:
|
|
|
|
* It retrieves the current value of `Me!PartNumber` and stores it in the `PN$` variable.
|
|
* It sets the `DocName` variable to the value of `PrimaryScreen$`.
|
|
* It uses the `DoCmd.OpenForm` method to open a form specified by `DocName`, with a link criteria specified by the `LinkCriteria` string. However, `LinkCriteria` is not defined in this code snippet.
|
|
* It navigates the form to specific controls using `DoCmd.GoToControl`: "PartName" and "PartNumber".
|
|
* It uses the `DoCmd.FindRecord` method to find a record with the value of `PN$`.
|
|
* It selects an object from a database, specifying a form name ("Restart Process Sheet") and selecting a specific field (`A_FORM`).
|
|
|
|
#### 4. Form Closure
|
|
|
|
After completing its tasks, the code closes the currently open form using `DoCmd.Close`.
|
|
|
|
### Assumptions and Context
|
|
|
|
This code appears to be part of a larger application that utilizes Microsoft Access's database features. The context in which this code is deployed is likely an application with multiple forms, some of which may require frequent updates or processing. The specific details of the database schema and form structures are not provided within this code snippet.
|
|
|
|
### Improvements and Suggestions
|
|
|
|
* Define the `LinkCriteria` string to ensure proper linking between the open form and other records in the database.
|
|
* Consider adding logging or debugging statements to help understand the behavior of the code, especially when encountering errors.
|
|
* Review the database schema and forms involved to optimize performance and efficiency.
|
|
* Ensure that the `PN$` variable is correctly validated for potential data corruption or invalid input.
