C# How to hide the Active Word Document in Window Task Bar

Using C#

I'm launching Word from my C# application.
//Create a new document from template
Object oTemplatePath = GetTemplateFile();
m_document = m_winword.Documents.Add(ref oTemplatePath, ref missing, ref missing, ref missing);

How to hide the Active Word Document in Window Task Bar? I do not want to hide the application. I only want the taskbar icon not to be visible.

Thank You
