I'm attempting to write a WebDAV to access contacts, but it is failing when I
try the authentication. I receive a WebException and InvalidCastException
conversion from string to double where indicated below (GetResponse). I've
verified the path to the DLL and the server/path works in the browser on the
server. I'm using the administrator login. It's on Win2003SBS. Any
assistance is appreciated. Thanks, Lisa
