Silent Property Example
By default silent property is false (i.e. it shows all the dialog boxes etc. which open while opening any website). Here I am opening bookmyshow.com in IE8. When this website is opening, it asks me if you want to "install Adobe Flash Player" or not, I just click on "X" on the top right to close this box. Now if I run this code again by uncommenting the line "objIExplorer.silent = True" then it does not show that "install adobe flash" dialog box.
Set objIExplorer = CreateObject("internetexplorer.application")
objIExplorer.visible = True
objIExplorer.silent = True
a=objIExplorer.silent
msgbox a
objIExplorer.Navigate2 "http://www.bookmyshow.com/"
Do While objIExplorer.busy
WScript.Sleep 500
Loop
