Can someone provide me the source code of a wrapper dll?

[Wolfie]

I want to pass a structure to a defined dll-function. This structure contains various sorts of data-types. I know I have to write a wrapper dll for that (what I did), but it doesn't seem to work. When creating my application, I get an "Unhandled exception" in my LabVIEW-file. It gives an error, which says: "The referenced memory at the instruction could not be written".

Can someone please provide me with an example of the source code for this wrapper dll I'm trying to create?

You should be able to pass the structure directly to the DLL without a wrapper. Structures (struct) in those nasty text-based languages behave like clusters in LabVIEW. Make a cluster that matches the structure. Be sure to respect word boundaries. If the structure has a 16-bit element in it and there is a 32-bit element right after it, insert a 16-bit (U16) PAD in your cluster. Flatten the cluster to string to pass it to the DLL. Make sure to byte-swap and word-swap first because LabVIEW uses big endian while Windows uses little endian.
