I'm writing a lotto program in vb.net 2005 and thought it might be a good idea to pull information off of the offical lotto home page(s) showing the last drawn numbers and display them on my form.

What am i doing wrong?

Dim a As AcroPDFLib.AcroPDFClass
Set a = CreateObject("AcroPDF.PDF.1")

Dim a As AcroPDFLib.AcroPDFClassSet a = CreateObject("AcroPDF.PDF.1")a.LoadFile("atmel_instruction_set.pdf")
