Running a client-side application using javascript in asp.net

Here is how to run a client-side application (.exe) using javascript in asp.net. I don't recommend it, because you probably have to lower your IE security (Tools -> Internet Options -> Security... and allow unsafe activeX).

    <script language="javascript" type="text/javascript">
        function btnSubmit_Click() {
            var WshShell = new ActiveXObject("WScript.Shell"); 
            WshShell.Run("calc.exe"); 
        }
    </script>
    <div>
        <asp:Button ID="btnSubmit" runat="server" Text="Submit" OnClientClick="btnSubmit_Click();" />
    </div>
