    Get thumbnail for a document

    Charly Orley Castrillon Madrid

      Hi Evereybody, and thanks in advance for your help

      I apologize for my bad english.

      I'm writing an add in for solidworks 2017 and I need to show in a picture box the thumbnail of a document selected in a treeview in a windows form that is runnig in solidworks.

      I'm trying to use the next function but null image is been returned.


          Public Function GetPreview(ByVal file As String) As System.Drawing.Image

              Dim pvf As New wpfPreviewFlowControl.wpfThumbnailCreator

              pvf = New wpfPreviewFlowControl.wpfThumbnailCreator()

              Dim size As System.Drawing.Size

              size.Width = 300 ' SIZE OF PREVIEW

              size.Height = 300 ' SIZE OF PREVIEW

              pvf.DesiredSize = size

              GetPreview = pvf.GetThumbNail(file) 'GetPreview is being returned NULL

          End Function


      Does anyone know why i'm getting a null image? If it isn't the correct way to get the thumbnail, does anyone know how to do it? As i said before, the form is running in solidworks so i don't have problems to open the document and read it.
