Is there any way werein we can copy the present address as permanent in the core HR address form and also in in the selfservice applications?
Thanks

Seriously, the Pointer is the right method.
Other things to check: If the DLL wants a Zero-terminated string/buffer, you may have to add a zero-byte to the end of the input [U8] array.  Make sure Length is wired and equals the input array-length.  I'm guessing Length should be passed by Value!(?)  Also, if reading-back a string (or array) then you'll (probably) have to pass-in a string/array at least as big as the result is supposed to be (just fill it with zeros.)
And if it still doesn't work, we're still missing something simple (like an incorrect datatype or calling-convention or broken DLL? .)
... and, thank you for backing me up, TonP!

Since the DLL function also wants the buffer length I doubt that it is expecting a zero termination character. But who knows! Maybe the OP misunderstands the function documentation (has he read that at all?).
If you really need zero termination you can do that yourself or just pass the string as string and configure the Call Library Node parameter to be a String too and use the C style String pointer type there. LabVIEW will take care to append a zero byte before passing the string pointer and if you also wire the output side of that parameter copy the contents from that pointer back into a string handle up to the first zero byte. It is obvious from this that a string buffer is not the right thing to pass to a CLN in LabVIEW if that buffer can legally contain zero bytes too.
