Can you be a little more specific than 'it doesn't work'?
Opened the NAV debugger to see what happens?

This is the error in Event Viewer

Had this error last week. Don't ask me why but don't use UseDefaultCredentials. Using System.net.NetworkCredential got rid of the error for me.

Wisa123,
Can you show me how you resolve this problem ?

Wisa123

using System.Net;

NetworkCredential cr = new NetworkCredential("userName", "password", "domain");
wst.Credential = cr;

Use those 2 lines instead of the UseDefaultCredential. Didn't try it now but it should work.

Wisa123,

Dont work again . When i add return parametar in my Codeunit function,
GetLocation(LotNo,loc) return Test:text, Test:= LotNo+Loc, and edit my C# app label.text=GetLocation(Lot,Lok), program works, app return value, but didnt want to modify field in NAV.
Only want to return value

Hi,

Rather than having the function return a Text, modify it so the functions returns nothing, but has a seperate VAR parameter of TEXT, then in your c# code, you pass a seperate string as a ref.

So the c# code would look like, i have boxed the 2 changes, just make sure you change the NAV side function and update your web reference






Try that.
