Form.Dispose Method (Boolean)

Disposes of the resources (other than memory) used by the Form.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

'Declaration
Protected Overrides Sub Dispose ( _
	disposing As Boolean _
)

Parameters

disposing
Type: System.Boolean
true to release both managed and unmanaged resources; false to release only unmanaged resources.

This method is called by the public Dispose method and the Finalize method. Dispose invokes the protected Dispose(Boolean) method with the disposing parameter set to true. Finalize invokes Dispose with disposing set to false.

When the disposing parameter is true, this method releases all resources held by any managed objects that this Form references. This method invokes the Dispose method of each referenced object.

Dispose will be called automatically if the form is shown using the Show method. If another method such as ShowDialog is used, or the form is never shown at all, you must call Dispose yourself within your application.

Notes to Inheritors

Dispose can be called multiple times by other objects. When overriding Dispose(Boolean), be careful not to reference objects that have been previously disposed of in an earlier call to Dispose. For more information about how to implement Dispose(Boolean), see Implementing a Dispose Method.

For more information about Dispose and Finalize, see Cleaning Up Unmanaged Resources and Overriding the Finalize Method.
