Senden von Informationen an die Zwischenablage
Verwenden der RunCommand-Methode
Verwenden Sie die RunCommand-Methode mit der acCmdCopy-Konstante , um den Inhalt des aktiven Steuerelements in einem Formular oder Bericht in die Zwischenablage zu kopieren.
Im folgenden Beispiel wird veranschaulicht, wie der Inhalt eines Textfelds mit der Bezeichnung "txtNotes" in die Zwischenablage kopiert wird.
Private Sub cmdCopy_Click()
Me!txtNotes.SetFocus
DoCmd.RunCommand acCmdCopy
End Sub
Verwenden der Windows-API
Fügen Sie den folgenden Code in den Deklarationsbereich eines Standardmoduls ein, um zum Senden von Informationen an die Zwischenablage Windows-API-Aufrufe zu verwenden.
