Syntax
Private Sub Form_Load( )
Private Sub Form_Unload(Cancel As Integer)
The Unload event has the following argument.
| Argument | Description |
|---|---|
| Cancel | The setting determines whether to unload the form. Setting Cancel to True (–1) prevents the form from being unloaded. |
Remarks
You can place initialization code in a form's Load event procedure. For example, you can specify default settings for controls and initialize form-level variables.
You can't cancel the Load event.
In an Unload event procedure, you can include any form-level validation code you might need to close the form or save the data it contains to a file.
If Cancel is set to True for a form that is modal, you may not be able to return control to the rest of the application.
