YES, YOU ARE RIGHT.
SINCE I WAS INVOLVED IN WEB PAGE SCRIPTS IN MY CURRENT PROJECT, I
REPLIED ACCORDINGLY. I WILL ALSO SAVE YOUR PREVIOUS POST FOR REFERANCE
IN FUTURE.

IS THERE ANYWAY TO FINDOUT WEATHER IE HAS GENERATED ANY MESSAGEBOX?
I CREATE A INSTANCE OF IE AND THEN NAVIGATE TO THE REQUIRED URL WITH
USERNAME AND PASSWORD. IF THERE IS ANY ERROR, THEN IE WILL GENERATE A
MESSAGE BOX OF THE ERROR AND WILL RETURN TO THE LOGIN PAGE.
IN SUCH CASE I WOULD LIKE TO ASK USER TO AGAIN INPUT THER USERNAME AND
PASSWORD, PROGRAMATICALLY CLICK ON OK BUTTON OF MESSAGEBOX AND AGAIN
INITIATE THE LOGIN PROCESS. USER WILL NOT BE ABLE TO SEE THE ERROR
MESSAGEBOS COZ I KEPT IE HIDDEN.

REGARDS,
SHETTY.
