## What it does
|
|
**Code Description**
|
|
=====================
|
|
|
|
### Overview
|
|
|
|
This VBA code snippet is a procedure that handles the `Form_Load` event in an Access application. The purpose of this code is to ensure that certain conditions are met before allowing the form to load.
|
|
|
|
### Breakdown
|
|
|
|
#### Option Compare Database
|
|
|
|
* This line specifies the comparison order for string comparisons in the current module.
|
|
* By setting it to `Database`, the code ensures that string comparisons are performed in a case-insensitive manner, taking into account database-specific collation settings.
|
|
|
|
#### Private Sub Form_Load()
|
|
|
|
* This line defines the procedure that will be executed when the form loads.
|
|
|
|
#### On Error GoTo die
|
|
|
|
* The `On Error` statement sets up an error-handling mechanism.
|
|
* When an error occurs in the code within the block, control is transferred to the label `die`.
|
|
|
|
#### If IsNull(Me![PartNumber]) Then End
|
|
|
|
* This line checks if the value of the `PartNumber` field in the current form's recordset is null or empty.
|
|
* If it is null, the procedure exits using the `End` statement.
|
|
|
|
#### DoCmd.SelectObject A_FORM, "DS Timesaver"
|
|
|
|
* This line uses the `DoCmd` object to select an existing record in the database based on the specified form and record name (`"DS Timesaver"`).
|
|
* The `A_FORM` parameter specifies that the record should be selected from the current form.
|
|
|
|
#### DoCmd.Close
|
|
|
|
* After selecting a new record, this line closes the currently open document.
|
|
|
|
#### Exit Sub
|
|
|
|
* This statement exits the procedure, indicating that no further code needs to be executed after the conditions have been met.
|
|
|
|
#### die:
|
|
|
|
* The `die` label is defined earlier in the code as the error-handling destination.
|
|
* When an error occurs, control transfers to this label, which contains the alternative code path.
|
|
|
|
### Purpose
|
|
|
|
The primary purpose of this code is to ensure that a specific record (`DS Timesaver`) is present in the database before allowing the form to load. If the required record does not exist, the form will exit without loading.
|
|
|
|
By using an error-handling mechanism and carefully selecting which actions to perform when an error occurs, this code demonstrates effective and efficient handling of potential issues that might arise during application execution.
