Trying to automate a process in console application - winapi

Question

I am trying to get my console application to simulate dragging and dropping a file, so far I have had no luck.
The system throws a win32 exception stating it cannot find the file, since I know that is not really the problem I was hoping someone could shed some light on what might be causing this behavior.
I suspect it might be DEP. I can drag and drop the file and the process runs as expected, but I need to automate this.
I have created a filewatcher and am right now trying to figure out how to get the code to work, prior to making it a windows service.
But right now I am really stuck on this win32 error.
public class Watcher
{
public static void Main(string[] args)
{
Run();
}
[PermissionSet(SecurityAction.Demand, Name = "FullTrust")]
public static void Run()
{
string[] args = System.Environment.GetCommandLineArgs();
// If a directory is not specified, exit program.
if (args.Length != 2)
{
// Display the proper way to call the program.
Console.WriteLine("Usage: Watcher.exe (directory)");
return;
}
// Create a new FileSystemWatcher and set its properties.
FileSystemWatcher watcher = new FileSystemWatcher();
watcher.Path = args[1];
/* Watch for changes in LastAccess and LastWrite times, and
the renaming of files or directories. */
watcher.NotifyFilter = NotifyFilters.LastAccess | NotifyFilters.LastWrite
| NotifyFilters.FileName | NotifyFilters.DirectoryName;
// Only watch jpg files.
watcher.Filter = "*.jpg";
// Add event handlers.
watcher.Changed += new FileSystemEventHandler(OnChanged);
watcher.Created += new FileSystemEventHandler(OnChanged);
watcher.Deleted += new FileSystemEventHandler(OnChanged);
watcher.Renamed += new RenamedEventHandler(OnRenamed);
// Begin watching.
watcher.EnableRaisingEvents = true;
// Wait for the user to quit the program.
Console.WriteLine("Press \'q\' to quit the sample.");
while (Console.Read() != 'q') ;
}
// Define the event handlers.
private static void OnChanged(object source, FileSystemEventArgs e)
{
// Specify what is done when a file is changed, created, or deleted.
Console.WriteLine("File: " + e.FullPath + " " + e.ChangeType);
Process.Start(e.FullPath + "c:\\demo\\kr-pano\\mpr.bat");
}

Apparently the issue is being caused because the filesystemwatcher is single threaded, and when I try to launch my new process it stops the old one from running. All I needed to do was stub out a new runpano function and call it from my code, its working now.
