1001: Invalid twitter username or password twitpic

Question

I am getting an invalid username or password error when trying to upload to twitpic. I am positive these are correct.

I am using Twitpic.net

 Twitpic tp = new Twitpic(data, ConfigurationManager.AppSettings["TwitterUsername"],        ConfigurationManager.AppSettings["TwitterPassword"]);
TwitpicResponse resp = tp.UploadAndPost("The Message");

Any help would be greatly appreciated.

Answer 1

Have you verified that you can actually read the settings from the application configuration? I.e. for example assign the values read from ConfigurationManager to temporary variables and debug/display/print them instead? If the read fails, the returned value will be null.

Then, when you can verify that you are indeed sending correct credentials - verify that you have authorized the Twitpic application on your Twitter account?

Additionally, hard-coding the configuration keys is not best practice - use constants or similar approach instead.
