Use the following function will change your web.config file

Private Function SaveConnectionStringKey(ByVal configFilePhysicalPath As String, ByVal key As String, ByVal value As String) As Boolean
      Dim m As ExeConfigurationFileMap = New ExeConfigurationFileMap
      m.ExeConfigFilename = configFilePhysicalPath
      Dim objConfig As Configuration = System.Configuration.ConfigurationManager.OpenMappedExeConfiguration(m, ConfigurationUserLevel.None)
      Dim objAppsettings As ConnectionStringsSection = objConfig.GetSection("connectionStrings")
      If Not objAppsettings Is Nothing Then
          objAppsettings.ConnectionStrings(key).ConnectionString = value
          objConfig.Save()
      End If
  End Function

To call the function use

SaveConnectionStringKey(Server.MapPath("~/web.config"), "EmployeeDB", "Server=etc;uid=etc.......")

Web.Config Section

XML

<connectionStrings>
  <add name="EmployeeDB" connectionString="Its a test" />
</connectionStrings>
