Re: How can I get an unsigned char string with nulls from a dll into LabVIEW 6i?
Well I would certainly go for the unsigned 8 bit array parameter method. That is the best one and contrary to your claim does not require any changes to the DLL. For the rest it is a good recommendation and the most direct approach to do, what the OP has to do. Rolf Kalbermatter
Re: How can I get an unsigned char string with nulls from a dll into LabVIEW 6i?
I am having difficulties using a DLL with is returning a string will nulls in the middle of it. I would be interested in seeing your example of using lstrcpyn from kernel32.dll or any other examples that you may have? Regards Jimbo

The types LabVIEW shows are the fundamental C types each C compiler should understand properly and means the same unless you have an exotic one for a 7 or 9 bit CPU. Rolf K
