Our company provides two downloads for our program, one includes the .Net
and the other does not. The problem is that the most of the times the user
has no idea if he or she already has the .Net installed on their local
computers or not so they are never sure if they should take the time to
download .Net only to find out that is already installed.
Is there a way to implement a button on a web page that a user can click and
popup a message box indicating if the .Net is already installed in their
local computer?
Thanks 4 1315
You can do that...as long as the browser is IE, if you're doing it online.
For an example of that, see : http://msdn.microsoft.com/library/de.../useragent.asp
If you don't need to detect while online, download sample code here : http://blogs.msdn.com/astebner/archi...18/231253.aspx
Or, if you want to detect from a Visual Studio deployment project, see this : http://support.microsoft.com/kb/315291/en-us

Thanks I will play around with this. By the way, we use Firefox as our
default browser and preliminary testing appear that it also works in Firefox
unless I am doing something wrong!
Am I missing something, why did you say the html version only works on IE?
Just curios.
Thanks

Hope that will help (I got it from somebody recently, did not try
though :))
The user agent string of Internet Explorer is changed to contain e.g.
..NET CLR 2.0.50727 so with script inside of IE you could parse
navigator.userA gent to look for that substring to check whether the
..NET framework runtime is installed:
function checkNETFramewo rk (version)
{
var pattern = new RegExp('.NET CLR ' + version);
return pattern.test(na vigator.userAge nt);
}
if (checkNETFramew ork('2.0')) { ... }
But don't expect other browsers to expose the MS .NET framework version
in the user agent string.
And there is no need to depend on client-side script to check the user
agent string, it is usually sent as a HTTP request header and that is
exposed server side in ASP.NET e.g. you could check
Request.UserAge nt.IndexOf(".NE T CLR " + "2.0") > -1 This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics |

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows.

For most users, this new feature is actually very convenient. If you want to control the update process,...
