problem with IMap interface

AdrianWelsh

I am using a standalone form to get a feature layer and then put it in an open ArcMap project.  It's a short code and it works in VBA, but I don't know why it wouldn't work in a VB.NET form.  Here is the code

Private Sub btnImportArcMap_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnImportArcMap.Click

        Dim pMxDoc As IMxDocument
        Dim pMap As IMap

        pMxDoc = m_pApp.Document
        pMap = pMxDoc.FocusMap

        Dim pFLayer As IFeatureLayer = New FeatureLayer
        Dim pFClass As IFeatureClass
        Dim pGPUtilities As IGPUtilities = New GPUtilities

        Try

            pFClass = pGPUtilities.OpenFeatureClassFromString("C:\Visualization.gdb\temp")

            pFLayer.FeatureClass = pFClass
            pFLayer.Name = pFClass.AliasName

            pMap.AddLayer (pFLayer)

            pMxDoc.UpdateContents()
            pMxDoc.ActiveView.Refresh()

        Catch ex As Exception

            MessageBox.Show (ex.Message)

        End Try

        MessageBox.Show ("Complete")
    End Sub

I have a sub before this that calls the m_pApp as IApplication and opens a new ArcMap project.  The problem with my code is at the pMap.AddLayer (pFLayer) part.  Can anyone tell me what I need to add or change to this code?

Thanks!

Thanks Neil!  That works now.  I wish there was some kind of way to reward you or give you points.  I sure hope that ESRI is working on improving this forum site...
