Windump Wrapper

You can easily bring your favourite command line programs into Windows forms using the System.Diagnostics.Process class. The following is a sample using the popular Windump packet sniffing program with a simple windows forms UI.

First, you must download and install Windump.

Create a new Windows forms project in Visual Studio 2008.

Add a textbox and a couple buttons to look like this:




Copy code below into the Form1.cs file.

Change the "process.StartInfo.Filename" to wherever you saved windump. Also, don't forget to set the "process.StartInfo.Arguments" to your ethernet interface. On my PC it is interface number 2. For a complete list of possible arguments, see the Windump Docs.
