ASP.NET programs sometimes need to know if the client is installed with .NET Framework. You can get some clues with the UseERAGENT attribute of the HttpRequest object, for example:
Private Sub Page_Load (Byvale AS System.Object, Byval E AS System.Eventargs) Handles MyBase.Load
'Put User Code to Initialize The Page Here
IF not me.ispostback then
Label1.text = Request.Useragent
END IF
End Sub
Possible output is:
Mozilla / 4.0 (Compatible; Msie 6.0; Windows NT 5.1; .NET CLR 1.1.4322)
Another maybe better approach:
Request.browser.clrversion property, but:
This Property is supported Only WHEN THE User Agent Is Internet Explorer Version 5.0 and later.
If The Common Language Runtime is Not Installed on The Client, The Property Value IS 0, 0, -1, -1.
IF More Than One Version of The Common Language Runtime In Installed On The Client, Clrversion Returns The Latest Version.
