Using Web Services in C#

dmauldin

I followed the walkthrough to start learning how to connect to web services in Nav 2009.

http://msdn.microsoft.com/en-us/library/dd355316.aspx

I typed in the code exactly as it is, but when I run it, I get a WebException was unhandled error at the




Customer[] list = service.ReadMultiple(filter.ToArray(), null, 100);

line. The error says 'The request failed with HTTP status 401: Unauthorized'.

Does anyone have an idea of what is causing this and how I can fix it?

User, under which you are running the application, must have correct permissions in NAV...

I gave that user super user rights and I still get the error.

hi

U can Try This Code

service.UseDefaultCredentials = False;
service.Credentials = New System.Net.NetworkCredential(UserName,Password);

I was able to do as vedant18 suggested and it worked. But of course i don't want to hard code a username and password. We will be using web services from our web site for customers to send in info. I'd like to use service.UseDefaultCredentials = true, but I keep getting the 401 Unauthorized when it creates the customer. We setup delegation but this still isn't working. Any ideas?
