Micosoft Word Interop

[Sam Horne]

Hi, I'm getting a null reference exception on the following code, which is attempting to create a word document. The error is occuring at 'wordDoc.Activate'. I have Word 2007 installed on both the server and on my machine, but I'm not too sure on how the interop stuff works. If someone can point me in the right direction, that would be great.

Imports Word = Microsoft.Office.Interop.Word

....

Dim wordApp = New Word.ApplicationClass()
Dim wordDoc = wordApp.Documents.Add
wordApp.Visible = True
wordDoc.Activate()

wordApp.Selection.ParagraphFormat.Alignment = Word.WdParagraphAlignment.wdAlignParagraphLeft
wordApp.Selection.TypeText("Some text")
wordApp.Selection.TypeParagraph()
