Looking for doc to pdf converter

[J Trahair]

Hi everyone. I'm looking for a VB.Net utility that converts an existing .doc, .docx, .xls to a .pdf file. I already have one that the user can choose as a (virtual) printer, but I'm looking for one that places the .pdf file in the same folder as the .doc(x) etc., ideally without asking any questions or giving any options. Preferably without the user having to print to the pdf.

Thanks in advance.
