Hi Winan,

To Open the page in Code-Behind do the following:

Dim sUrl As String = "MyPage.aspx"
Dim sFeatures As String = "'height=320;width=160;left=100;top=50'"

' Create a client script to open the window
Dim sScript As String
sScript &= "<script language=javascript>"
sScript &= "window.open('" & sUrl & "',''," & sFeatures & ");"
sScript &= "</script>"

' Write it into the output stream for immediate execution
Response.Write(sScript)

To Open using Javascript on the client side:

<a href="javascript:my_window=window.open('MyPage.aspx','my_window','height=320;width=160;left=100;top=50');my_window.focus()"> Go to MyPage</a> 

There is no straight-forward way to disable the back button since the browser does not expose those functionalites through its object model. However, you could open a window with no menubar/toolbar/addressbar, and
disable context menu.
