Hi jitender Use Window.Alert() method of the Document object to achieve this purpose. Below is the illustration of how will you do it: button_click() { // ... // Manipulation code goes here... //... WebBrowser1.Document.Window.Alert(Authentication Successful); } I'm sure this will help you. Don;t forget to accept this as answer if it helps! Thanks.
