Tille,
maybe the documentation of the Call Library Function Node in LabVIEW
gives you some ideas how you could set this up. You can find the docu
also
here. Specially the part ActiveX and Adept to Type (quite in the end) will be interesting for you.
But to be fair, most part has to be "prepared" by the DLL itself. If
the picture is passed by value, you will have no chance, regardless
what setting you choose in LV.
