Implementing dynamic Password change

Question

Dear friends.
I am working with SAP.Net So i am wondering how to solve the first time login for SAP using .Net as front end.
Moreover in the SAP Passwords will be changed every 3 months i would like to know how to handle such scenarios using .net to handle those changes in the SAP.
Cheers

I assume you want a code sample? Here you are (untested, so consider it as pseudo-code):
SAPProxy proxy = new SAPProxy();
Destination dest = new Destination();
// initialize your Desitnation accordingly here
proxy.Connection = Connection.GetConnection(dest);
bool repeat = false;
do
try
  proxy.Connection.Open()
  // Note: I think that the need to change password causes an exception here, but I'm not sure. So better try..
catch(Exception ex)
// Check if the exception was because of password needs to be changed
  PasswordDialog passDlg = new PasswordDialog(dest.Password);
  passDlg.ShowDialog();
  string passwordChangingConnectionString = dest.ConnectionString + " NEWPASS=" + passDlg.NewPassword;
  proxy.Connection.Dispose();
  proxy.Connection= Connection.GetConnection (passwordChangingConnectionString);
repeat = true;
} while(repeat);
proxy.Call();
