I have problem setting the password for an ADAM user using C#. I used
the SetPassword code given in the Microsoft page, changed several
parameters, but ran into an exception. I wonder if other people have
solved this problem. But I have searched Google groups for a couple
days but still couldn't get a solution.
I copied the code from:
http://msdn.microsoft.com/library/de...r_password.asp
Then when the program reaches the first call of:
objUser.Invoke("SetOption", ...);
It throws the an exception with the following information:
Message:
Exception has been thrown by the target of an invocation.
BaseException:
Exception from HRESULT: 0x80005008.
Inner Exception:
System.Runtime.InteropServices.COMException (0x80005008):

For your information, here is the code I have:

try
{

objUser.RefreshCache();
}

{

Debug.WriteLine(" " + e.Message);
return;
}

here**
objUser.Invoke("SetOption", new object[]

}

Debug.WriteLine("TargetSite\n" + e.TargetSite);
return;
}
Debug.WriteLine("Success: Password set.");
return;
}
<-- code ends -->
Thank you very much and I appreciate anyone who has any suggestions!
