.net – Faxing PDF file using .Net application


I developed a windows service to fax files using VB.NET. It is working for the file formats .bmp,.jpeg. But it is not working for the file type .PDF.

I am using FaxComLib (COM .dll) to send fax. I am getting following error when the service tries to fax .PDF file. "System.Runtime.InteropServices.COMException (0x80070483): Operation failed. at FAXCOMEXLib.FaxDocumentClass.ConnectedSubmit(FaxServer pFaxServer)

What could be the problem?


Best Solution

Wouldn't you need to flatten the PDF into a sequence of page images, perhap as TIFF's?
