You can't change this title.

The alert box is generated by the browser and the title is not something that can be controlled via javascript.

The best you can do is create your own alert box in javascript (for example using jQuery UI).

See this SO question.

Look at JavaScript alert title header or How to edit a JavaScript alert box title?.

Use custom alert message box, for changing the title else you can't change the title

for more details check this link

http://javascript.internet.com/miscellaneous/custom-alert-box.html

you can try this

MsgBox("Hi", MsgBoxStyle.MsgBoxSetForeground, Title)

it will display the title of your web page. for eg if your web page has title "My home page", then the title of the massage box will be "My home page".
