QTP queries-Help Required for valid and invalid data

[SonalBalte]

I have one query...
Can any 1 please do help me???????//
I am having QTP 10.0 version.
How will QTP understand the valid data feed and invalid data feed?
I have also tried for one example.
Lets say my password for login window is "a".
Instead of "a", I have feeded the password as "1".
It should fail the test case in this scenario.
But I am not getting how to make QTP understand that the login password is "a" and not "1",and hence it should fail the test case?

Hi Sonal,
enter login crediantials with wrong password and try to login in your application. As the password is incorrect, application will give error. Insert a checkpoint on that error element.
