Specifies whether the Close button on a form is enabled. Read/write Boolean.
expression Required. An expression that returns one of the objects in the Applies To list.
The CloseButton property uses the following settings.
|Yes||True||(Default) The Close button is enabled.|
|No||False||The Close button is disabled and the Close command isn't available on the Control menu.|
You can set the CloseButton property only in form Design view.
If you set the CloseButton property to No, the Close button remains visible but appears dimmed (grayed), and you must provide some other way to close the form — for example, a command button or custom menu command that runs a macro or event procedure that closes the form.
