In an easy way, if you already got the handle, you can obtain all the processes

Process.GetProcesses()

then compare your handle

IntPtr myHandle = ....    
foreach (Process process in processes)
                if (process.Handle = myHandle)
                    ....

and at last get the Name of the process

foreach (Process process in processes)
     if (process.Handle = myHandle)
     {
          string temp = process.ProcessName;
          ....
     }

You have the Process class defined inside the namespace

System.Diagnostics

Edit: Forgot that you need to call GetWindowThreadProcessId first to get the pid from the handle. More info here. And if you look the Pinvoke page here you can find a complete VB.Net sample.

Process.GetProcessById(id).ProcessName

In the System.Diagnostics namespace, see here for details.
