private:
void FindProperty()
{
// Creates a new collection and assign it the properties for button1.

PropertyDescriptor^ myProperty = properties->Find( "Opacity", false );
// Prints the property and the property description.
textBox1->Text = myProperty->DisplayName + "\n" + myProperty->Description;
}
void FindProperty()
{
// Creates a new collection and assign it the properties for button1.
PropertyDescriptorCollection properties = TypeDescriptor.GetProperties(button1);
// Sets a PropertyDescriptor to the specific property.
PropertyDescriptor myProperty = properties.Find("Opacity", false);
// Prints the property and the property description.
textBox1.Text = myProperty.DisplayName + '\n' + myProperty.Description;
}
Private Sub FindProperty()
' Creates a new collection and assign it the properties for button1.
Dim properties As PropertyDescriptorCollection = _
TypeDescriptor.GetProperties(button1)
' Sets a PropertyDescriptor to the specific property.
Dim myProperty As PropertyDescriptor = properties.Find("Opacity", False)
