New Post: Clip two Shape with Mapwingis : Resulting shapefile has no shapes?

Hello good day
I have doubts about how to do the code to do geoprocesses, and I have been progressing several codes but I do not generate the union, intercession or merge, you could help me with those codes, the code I have is this:
Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click

    Dim ruta1 As String = ("C:\Users\mmmmmm\pruevas\col.shp")
    Dim ruta2 As String = ("C:\Users\mmmmmm\pruevas\radsol.shp")
    Dim sfinput As New MapWinGIS.Shapefile
    Dim sfClip As New MapWinGIS.Shapefile
    Dim sfOverlay As New MapWinGIS.Shapefile

    sfinput.Open(ruta1)
    sfOverlay.Open(ruta2)
    sfClip = sfinput.Merge(False, sfOverlay, False)
    'sfClip = sfinput.Clip(False, sfOverlay, False)

    If sfClip Is Nothing Then
        MessageBox.Show("Failed to calculate Clip :" + sfinput.ErrorMsg(sfinput.LastErrorCode))
    Else
        sfClip.SaveAs("C:\Users\Juan\Desktop\mmmmmm\mergenose.shp")
        AxMap1.AddLayer(sfClip, True)
    End If
End Sub
