How to send a DLL a lpcwstr input?

[InfiniteNothing]

Hello, I have a windows DLL and it's asking for a lpcwstr input. When I setup my DLL call it gives me the following options for string types: C String Pointer, Pascal String pointer, String Handle, String Handle Pointer. None of these seem to work in my case. I'm guessing that this is because LPCWSTR is unicode based where most of the Labview string types have 1 byte per character. Has anyone had any luck feeding a LPCWSTR input?

Have you seen this?

Yes, I can't say it made much sense to me though. It sounded like the OP was either trying to call the DLL from C or call a LV DLL from C. I'm trying to call a DLL from LV. Let me know if I'm wrong. An example of calling a DLL that requires a LPCWSTR from LabVIEW would be great.

How about this?

Excuse the male pattern blindness but I didn't see any links to the mentioned STR_ASCII-Unicode. I searched the built in palette but I can't find it. Also, I still don't know which of the four string parameter options to use for the DLL call.

Ah, figured out the first question: the vi is in vi.lib/registry.llb

The DLL still isn't acting like it's getting a proper input though. I'm not quite sure why. I'll keep trying different things here.

Excuse the frequent updates. I think it all works now. In my specific case I had to use the C String Pointer  format with the constant check box checked. Thanks!
