I want to use the ArcMap Identify-Tool inside a WindowsForm. So I've created a button and added a clickevent:     Private Sub btnIdentify_Click(sender As Object, e As EventArgs) Handles btnIdentify.Click         Dim intObjectID As Integer = lstResults.SelectedValue         Dim pLayer As ILayer2 = pDocument.FocusMap.Layer(0)         DoIdentify(pLayer, intObjectID)     End Sub ‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ ‍ ‍ ‍ ‍ ‍ I've also created a sub procdedure similar to the one in the ArcObjects API Reference for .NET     Private Sub DoIdentify(ByVal pLayer As ILayer, ByVal intObjectID As Integer)         If pActiveView Is Nothing Or pLayer Is Nothing Or intObjectID <= 0 Then             Return         End If           Dim pMap As IMap = pActiveView.FocusMap         Dim pIdentifyDialog As IIdentifyDialog = New IdentifyDialogClass()         pIdentifyDialog.Map = pMap           pIdentifyDialog.ClearLayers()         Dim pScreenDisplay As IScreenDisplay = pActiveView.ScreenDisplay           Dim pDisplay As IDisplay = pScreenDisplay         pIdentifyDialog.Display = pDisplay           pIdentifyDialog.AddLayerIdentifyOID(pLayer, intObjectID)         pIdentifyDialog.Show()     End Sub ‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ This code works perfectly fine. But I really want to use the new IIdentifyDialog2 Interface. But if I change the code to     Private Sub DoIdentify(ByVal pLayer As ILayer, ByVal intObjectID As Integer)         If pActiveView Is Nothing Or pLayer Is Nothing Or intObjectID <= 0 Then             Return         End If           Dim pMap As IBasicMap2 = pActiveView.FocusMap         Dim pIdentifyDialog As IIdentifyDialog2 = New IdentifyDialogClass()         pIdentifyDialog.BasicMap = pMap           pIdentifyDialog.ClearLayers()         Dim pScreenDisplay As IScreenDisplay3 = pActiveView.ScreenDisplay           Dim pDisplay As IDisplay = pScreenDisplay         pIdentifyDialog.Display = pDisplay           pIdentifyDialog.AddLayerIdentifyOID(pLayer, intObjectID)         pIdentifyDialog.Show()     End Sub ‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍   I get a NullReferenceException at pIdentifyDialog.ClearLayers() I already tried so many things but somehow I can't get it to work with the new Identify-Tool. Does anyone know the answer? ... View more
