Property Handler

I'm trying to use the Windows API Code Pack 1.1 to write extended attributes to files of type .pcap. Here's the code I'm using:

private void SetExtendedAttributes(string sFilePath)
		ShellObject file = ShellObject.FromParsingName(sFilePath);
		ShellPropertyWriter writer = file.Properties.GetPropertyWriter();
		writer.WriteProperty(SystemProperties.System.Author, "me myself I");

		// Closing the writer actually commits the changes.

Open in new window

The program errors on the line: ShellPropertyWriter writer = file.Properties.GetPropertyWriter()

with the error:

-		$exception	{"Unable to get writable property store for this property."}	System.Exception {Microsoft.WindowsAPICodePack.Shell.PropertySystem.PropertySystemException}

+		InnerException	{"Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG))"}	System.Exception {System.Runtime.InteropServices.COMException}

So I dug around and I believe that the .pcap file extension doesn't have a Property Handler. If I use a .jpg or .docx file then the code works fine. So my question is, how do I create a Property Handler for .pcap files? I'd like to use C# .Net in VS2010. Can you help?

Looks like there is no property handler registered for the .PCAP file extension.  Generally the developer creating and using this extension should create the property handler.  If not, then perhaps you need to write one for this then.  

Here is a link that should provide you with information regarding writing a handler:

Dan7el, thanks for the comment. I've read that web page, but it's still too complicated for me. I'm looking for an actual example that I can modify, or some simple steps to create the property handler. I tried following the MSDN instructions, but got no where.

I'd still like to get an example of a Property Handler that can be written for a specific extension. In my case I trying to get a Property Handler for a .pcap file. Can nobody out there help me? I've read tons of documentation and am left still wondering how to do it.
