Open new window in a specific URL

Hi!! I have delphi 7 and i would like to make a program like this: have a button and a textbox, and when the button is pressed, it should open a new browser window with the url in the textbox ("http://www.microsoft.com" for example). Also, can i automaticaly close the window after some time? Please somebody give me any idea how to make this. Thanks

assuming your TEdit control is named "Edit1" the code below will do the trick:

uses ShellApi;

procedure OpenUrl;
begin
ShellExecute(self.WindowHandle,'open',PChar(edit1.text),nil,nil, SW_SHOWNORMAL);
end;
