I have figured it out, so awesome thanks for the person who posted the http://social.msdn.microsoft.com/Forums/en-US/csharpgeneral/thread/a5bcfc8a-bf69-4bbc-923d-f30f9ecf5f64 link, this is exactly what I was looking for!
Here’s a the full solution:
static class Program
{
[STAThread]
static void Main(params string[] Arguments)
{
SingleInstanceApplication.Run(new ControlPanel(), NewInstanceHandler);
}
public static void NewInstanceHandler(object sender, StartupNextInstanceEventArgs e)
{
string imageLocation = e.CommandLine[1];
MessageBox.Show(imageLocation);
e.BringToForeground = false;
ControlPanel.uploadImage(imageLocation);
}
public class SingleInstanceApplication : WindowsFormsApplicationBase
{
private SingleInstanceApplication()
{
base.IsSingleInstance = true;
}
public static void Run(Form f, StartupNextInstanceEventHandler startupHandler)
{
SingleInstanceApplication app = new SingleInstanceApplication();
app.MainForm = f;
app.StartupNextInstance += startupHandler;
app.Run(Environment.GetCommandLineArgs());
}
}
}
Thanks alot all, and especially the person who posted that link I mentioned above but I guess he deleted his answer?

Kenny
