Calling DLL from VB.NET



Folks,
I'm trying to call an unmanaged function from VB.NET and
keep getting "Object reference not set to an instance of
an object" error.

The code that i wrote can be found at:
http://www.nomorepasting.com/paste.php?pasteID=5973

The dll (if some kind soul has the time to compile and run
the code) can be found at:
ftp://ftp.astro.com/pub/swisseph/sweph.zip
The original function definition in the dll is:
char *FAR PASCAL swe_get_planet_name(int ipl, char
*spname);
Any help is greatly appreciated.
Thanks,
Leftie
