Guten Morgen
anbei mein Problem.
Ich möchte den Inhalt einer PictureBox (Inventor Methode
ClientView - also kein Text oder Bitmap) in die Zwischenablage kopieren.
Bei Text usw klappt dies.
Habe folgende beiden Methoden benutzt.
Clipboard.SetData Screen.ActiveControl.Picture
Alternativ
CopyEntirePicture picTest
Bringt nur ein leeres Feld ins Clipboard.
Anbei das Modul welches hinter CopyEntirePicture liegt.

Ich weiss das dieses wieder mal ein VB Problem ist, aber ich hoffe mal : daywa1k3r PaulSchuepbach und Konsorten
sind schon wach.

Es gab mal Zeiten, da haben wir und gefreut im 2D Ansichten gemalt zu haben.
Lasst uns dies nicht vergessen wenn wir Ansichten erstellt bekommen
