i can get frob ,
but i can't use flickr.AuthGetToken(frob)
debug output :Authentication failed : Invalid frob (108)
my frob like this :"4563432-d06b226708777e6e"
i don't know why?

this my code :
private void button1_Click(object sender, System.EventArgs e)

Flickr flickr = new Flickr(ApiKey, SharedSecret);

frob = flickr.AuthGetFrob();

string url = flickr.AuthCalcUrl(frob, AuthLevel.Write);



private void button2_Click(object sender, System.EventArgs e)
Flickr flickr = new Flickr(ApiKey, SharedSecret);

Auth auth = flickr.AuthGetToken(frob);

catch (FlickrException ex)
Console.WriteLine("Authentication failed : " + ex.Message + "\r\n");

Can you give me more details on what you are doing? Are you definitely going to the Flickr web site and authenticating before you are requesting the token?

I'm seeing the same problem, but only on Vista. Vista is doing VERY bad stuff with the following:

System.Diagnostics.Process.Start("iexplore", flickrUrl);

First , it starts the iexplore process.
Then, it quickly exits it.
Then another iexplore process is started (with the url).

The result, of course, is that the first process almost immediately fires off its "exited" event, before any authorization has occurred. Result = "invalid frob".

Argh. Anyone have a solution for this?

hi All
i am writing an application for flickr by using flickcurl API , but
invalid frob problem is comeing , when i use getFrob() which passes flickcurl *fc as parameter ,
but whatever it frob it is returning is not acceptable by getToken()
it is telling invalid frob for authentication ..

If any anyone knows the solution please reply ..

This isn't the Flickrcurl web site - I don't know C at all, and have no idea what a *fc parameter is.

You must however make sure you are authenticating the application in between getting the Frob and calling getToken.
