Unable to connect to DropBox

Feb 21, 2013 at 1:33 PM
I tried to build a Windows Phone app using Sharpbox. I followed the code sample given in Nokia Developer (http://www.developer.nokia.com/Community/Wiki/Dropbox_with_Windows_Phone) However, I am unable to get a valid token in LoginCallback() func, token returned is null.

From the IAsyncResult in LoginCallback(), the token and configuration member contains valid value, but I found that there is an exception in result.AsyncState.OpenResult.errorResult ---- (System.UnauthorizedAccessException: Attempted to perform an unauthorized operation.)

I tested my token.txt by the given TokenGenerator.exe, and it can return the root correctly.

Can anyone give me a helping hand??

Regards!!!
