In my application one lastposition button available.When the client will click on this button one graphic will b added to the map which denoting the last position of vehicle.Now everything is working fine.Now my requirement is , How to auto refresh this last position location on map in each 2 minute interval without cliking the button?Please help me ASAPhere is my code Private Sub LnkLastPosition_Click(sender As Object, e As System.Windows.RoutedEventArgs) Handles LnkLastPosition.Click
LastPosition()
End Sub
Private Sub LastPositionFinalRunning(ByVal sender As Object, ByVal e As SelectLastPositionCompletedEventArgs)
If e.Result.Count > 0 Then
'Dim geometry1 As New Point(csys, rs("lon"), rs("lat"))
.............
Dim graphic As New Graphic() With
{
.Geometry = New MapPoint(Convert.ToDouble(gpsNMEASentence(4)), Convert.ToDouble(gpsNMEASentence(2))),
.Symbol = TryCast(LayoutRoot.Resources(colourstyle), Symbol)
}
graphic.Attributes.Add("STRHOTSPOT", strhotspot)
AddHandler graphic.MouseLeave, AddressOf Graphic_MouseLeave
AddHandler graphic.MouseEnter, AddressOf Graphic_MouseEnter
graphicsLayer.Graphics.Add(graphic)
Dispatcher.BeginInvoke(Sub() ZoomToResolution(MyMap, 0.00000220549302222, New MapPoint(Convert.ToDouble(gpsNMEASentence(4)), Convert.ToDouble(gpsNMEASentence(2)))))
MyMap.Visibility = Windows.Visibility.Visible
