Hinweise

Die Rahmenart des Formulars bestimmt, wie der äußere Rand des Formulars angezeigt wird.The border style of the form determines how the outer edge of the form appears. Zusätzlich zum Ändern der Rahmen Anzeige für ein Formular verhindern bestimmte Rahmen Stile, dass das Formular mit einer Größenanpassung versehen wird.In addition to changing the border display for a form, certain border styles prevent the form from being sized. Beispielsweise ändert die Rahmenart FormBorderStyle.FixedDialog den Rahmen des Formulars in den eines Dialog Felds und verhindert, dass die Größe des Formulars geändert wird.For example, the FormBorderStyle.FixedDialog border style changes the border of the form to that of a dialog box and prevents the form from being resized. Die Rahmenart kann sich auch auf die Größe oder Verfügbarkeit des Beschriftungs leisten Abschnitts eines Formulars auswirken.The border style can also affect the size or availability of the caption bar section of a form.

Hinweis

Beim Sizable-Format ist es nicht möglich, die Größe des Fensters unterhalb eines bestimmten minimal Werts zu ändern, auch wenn Sie ControlBox auf false festgelegt und Text eine Zeichenfolge der Länge 0 (null) zugewiesen haben.With the Sizable style, it is impossible to resize the window below a certain minimum value, even if you have set ControlBox to false and assigned a zero-length string to Text. Sie sollten dieses Problem umgehen, indem Sie stattdessen den SizableToolWindow-Stil verwenden.Consider working around this by using the SizableToolWindow style instead.
