How do I center a paragraph in Word using vb.net? - vb.net

Question

I am using Visual Studio 2015 and coding in vb.net and importing Microsoft.Office.Interop.Word . I am using the following code to create a one page Word document with only two lines. How can I center, both vertically and horizontally these two lines? Also, is there a way to put both lines, with a line break in between, in one paragraph rather than using two? I am very new to this type of programming so please be specific. Thanks.
Private Sub CreateTitlePage2()
Dim wdApp As Microsoft.Office.Interop.Word.Application = New Microsoft.Office.Interop.Word.Application
Dim wdDoc As Microsoft.Office.Interop.Word.Document = New Microsoft.Office.Interop.Word.Document
Dim wdPara1 As Microsoft.Office.Interop.Word.Paragraph
Dim wdPara2 As Microsoft.Office.Interop.Word.Paragraph
wdDoc.Application.Visible = False
wdPara1 = wdDoc.Content.Paragraphs.Add
wdPara1.Range.ParagraphFormat.Alignment = WdParagraphAlignment.wdAlignParagraphCenter
wdPara1.Range.Font.Bold = True
wdPara1.Range.Text = "BINDER DOCUMENT"
wdPara1.Range.InsertParagraphAfter()
wdPara2 = wdDoc.Content.Paragraphs.Add
wdPara2.Format.SpaceBefore = WdVerticalAlignment.wdAlignVerticalCenter
wdPara2.Range.Font.Bold = True
wdPara2.Range.Text = "Created: " + formattedDate2
wdPara2.Range.InsertParagraphAfter()
wdDoc.SaveAs(binderNameDoc)
wdDoc.Close()
wdApp.Quit()
End Sub

#Ross: It would help if you'd describe HOW it's "not working". However...
WdVerticalAlignment is not valid applied to a paragraph object, I'm surprised you're not getting a compiler error. See https://msdn.microsoft.com/en-us/library/aa224305(v=office.11).aspx.
If you want to center something vertically on the page then it must be done via the PageSetup object and then it will apply to the entire SECTION. See https://msdn.microsoft.com/en-us/library/office/ff838676.aspx?f=255&MSPPError=-2147217396
If you document is really only the one page, as you say, then you don't need to worry about the SECTION part as the document will have only the one.
RE Line break: Insert ANSI 11 character (vbVerticalTab) for a line break (what you get when pressing Shift+Enter in the Word application).
