hi,

below is my code to get server date time. I create this using webservices.asmx . Once run i upload the web reference to my server using IIS as ServerTime.

Imports System.Web.Services
Imports System.Web.Services.Protocols
Imports System.ComponentModel


<System.Web.Services.WebService(Namespace:="http://123.111.11.66")> _
<System.Web.Services.WebServiceBinding(ConformsTo:=WsiProfiles.BasicProfile1_1)> _
<ToolboxItem(False)> _
Public Class ServerTime
    Inherits System.Web.Services.WebService

    <WebMethod()> _
    Public Function ServerDateTime() As String
        Dim dateTimeStr As String
        Dim tZn As TimeZone             'get the time zone 
        Dim tZnNameStr As String        'time zone name (CST, EST, etc) 
        tZn = System.TimeZone.CurrentTimeZone 'get name of time zone
        If tZn.IsDaylightSavingTime(Now) Then
            tZnNameStr = tZn.DaylightName
        Else
            tZnNameStr = tZn.StandardName
        End If
               dateTimeStr = Format(Now, "MM/dd/yyyy hh:mm:ss tt")
        Return dateTimeStr
    End Function
End Class

below is the way i call from my application to compare the server datetime and my pc datetime....But i'm not getting the response from the server site.....when i run my application it's just compare with my pc time......

If GetServerDateTime() < Format(Now, "MM/dd/yyyy hh:mm:ss tt") Then
              MsgBox("You datetime not valid")
                Application.Exit()
                         End If

Please help....i think i have directed to wrong webservice.....how do i make to correct webservice.....any idea ????
