Hi,
I am Norman.
I have a simple problem for which I don't know the answer.
I have a single form that I want to use for both add and view user. I was able to
successfully add a user. After adding the user I want the user details to be displayed.
Can somebody throw some lights on what I need to do. I am pasting my code with this.
