Hi All,

I want to print pdf document silently.
But adobe does not get closed after printing of document.

I have tried following code. It works for all type of documents but failed for pdf document.
I serached on google, i found the option to Kill adobe exe after printing of document.
Does any one have better solution than this?

Thanks in advance,
Pushkar

What I have tried:

Process oProcess = new Process();
oProcess.StartInfo.FileName = PDFFilePath;
oProcess.StartInfo.UseShellExecute = true;
oProcess.StartInfo.CreateNoWindow = true;
oProcess.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
oProcess.StartInfo.Verb = "print";
oProcess.Start();
oProcess.WaitForExit();
Success = true;
