Problem mit 2. Formular

[Khabarakh]

Zitat von Elvis:

Wenn du ein Form normal aufrufst, wird mit Close gleich ein Dispose ausgeführt.

Sozusagen ein sauberer Selbstmord .

Zitat:

When a form is closed, all resources created within the object are closed and the form is disposed. You can prevent the closing of a form at run time by handling the Closing event and setting the Cancel property of the CancelEventArgs passed as a parameter to your event handler. If the form you are closing is the startup form of your application, your application ends.

The one condition when a form is not disposed on Close is when it is part of a multiple-document interface (MDI) application, and the form is not visible. In this case, you will need to call Dispose manually to mark all of the form's controls for garbage collection.
