ToolboxBitmapAttribute-Konstruktor (Type)

Initialisiert ein neues ToolboxBitmapAttribute-Objekt auf Grundlage einer 16 x 16-Bitmap, die als Ressource in einer angegebenen Assembly eingebettet ist.

Namespace: System.Drawing
Assembly: System.Drawing (in system.drawing.dll)

Syntax

'Declaration
Public Sub New ( _
    t As Type _
)
'Usage
Dim t As Type

Dim instance As New ToolboxBitmapAttribute(t)

public ToolboxBitmapAttribute (
    Type t
)

public:
ToolboxBitmapAttribute (
    Type^ t
)

public ToolboxBitmapAttribute (
    Type t
)

public function ToolboxBitmapAttribute (
    t : Type
)

Parameter

• t
  Ein Type, dessen definierende Assembly nach der Bitmapressource durchsucht wird.

Hinweise

Dieser Konstruktor sucht in der Assembly, die den vom t-Parameter angegebenen Typ definiert, nach eingebetteten Ressourcen. Der Konstruktor sucht nach einer Ressource mit dem Namen namespace.classname.bmp, wobei namespace für den Namespace steht, der die Definition der vom t-Parameter angegebenen Klasse enthält. Wenn sich ControlA beispielsweise im in AssemblyA.dll gespeicherten NamespaceA befindet, sucht der Konstruktor in AssemblyA.dll nach einer Ressource mit dem Namen NamespaceA.ControlA.bmp.

Beispiel

Im folgenden Codebeispiel wird veranschaulicht, wie Sie mithilfe des ToolboxBitmapAttribute-Konstruktors das Symbol des Schaltflächen-Steuerelements auf das Toolboxsymbol für ein UserControl mit dem Namen StopSignControl3 festlegen.
