PDF to new browser window

Cannot figure out how to open a pdf document into a new browser window. The code with which I generate the pdf is:

Dim doc As Document = New Document(tstr)
Dim builder As DocumentBuilder = New DocumentBuilder(doc)
builder.InsertHtml(tstr) 'html text to show
doc.ViewOptions.ZoomPercent = 100
With doc
    .SaveOptions.PdfExportImagesFolder = System.Configuration.ConfigurationManager.AppSettings("PathImages")
    .Save("myfile.pdf", SaveFormat.Pdf, SaveType.OpenInBrowser, Response)
End With
