Beispiele

Im folgenden Codebeispiel wird einer ListBox mit den folgenden Membern ein Schatten hinzugefügt:The following code example adds a shadow to a ListBox by using the following members:

Dieses Beispiel ist für die Verwendung mit einem Windows Form konzipiert.This example is designed to be used with a Windows Form. Um dieses Beispiel auszuführen, fügen Sie diesen Code in ein Formular ein, und nennen Sie die AddShadow-Methode, wenn Sie das Paint-Ereignis des Formulars verarbeiten.To run this example, paste this code into a form and call the AddShadow method when handling the form's Paint event. Vergewissern Sie sich, dass das Formular eine ListBox mit dem Namen listBox1enthält.Verify that the form contains a ListBox named listBox1.
