i’m trying to interface with a hardware- which controls laser projectors- called “Netlase”.
the hardware manufacturer has sent me a dll+documentation, which which i should be able to communicate with the device.
however, as soon as i reference the dll via the project explorer and then save the plugin, it will throw an error (see picture);
what’s possible causes for that? i know that’s a rather general question, but as i haven’t referenced dll’s a lot in my own plugins yet (actually only once), it might be something very general i’m doing wrong…
any hints much appreciated!
as i’m havig trouble uploading my screenshot, here’s the error message:
Die Metadatendatei “xyz…/netlase.dll” konnte nicht geöffnet werden - ‘Es wurde versucht, eine Datei mit einem falschen Format zu laden.’
is the .dll a native or managed one?
i tried to find out (any tools/hints for that?), no info from the manufacturer yet.
would this be a valid error code for it being unmanaged?
suppose it is unmanaged, would it be sufficient to use DLLImport function (to bring in every function from the dll i want to use)? as i understood that function is mostly used when doing wrappers for c++ in c#?
thanks a lot!
have a look if the dll has something called a COM Interface. If it has, you can include it properly by using monodevelop or visual studio.
as far as i understand the dll should export a DllRegisterServer if there was a COM interface- correct me if i’m wrong- the list of exported functions show nothing like that however(see attached file)…

for everybody else having similar troubles, using
and inside your node class:
private static extern int yourDLLExportedFunction();
works fine for me. yourDLL.dll needs to be in the same folder as vvvv.exe, or you specify a path instead.
yourDLLExportedFunction is the function of interest, exported by yourDLL.dll; which should be declared in it’s documentation.
after importing it this way i’ve been able to use the functions right away; copy paste edit the lines for additional functions to import.
