FileSystemWatch er file in use problem

[Charlie Kunkel]

I need help. I have a directory I'm watching for creation of .TIF
files, whereupon creation, I need to launch a process (command line
exe) that converts the TIF file to a postscript file. (using
tif2ps.exe) The problem is, I can't open the .TIF file as long as my
application's running! tif2ps.exe always tells me "Cannot open file".

Here's the code in my Windows C# App:

private void button1_Click(o bject sender, System.EventArg s e)
{
FileSystemWatch er objFSW = new FileSystemWatch er();
objFSW.Path = "c:\\BizDocs\\v ault";
objFSW.Filter = "*.tif";
label1.Text = "Watching " + objFSW.Path;
//Setup Events
objFSW.Created += new FileSystemEvent Handler(FileCre ated);
//Start Things up
objFSW.EnableRa isingEvents = true;
}
public static void FileCreated(obj ect source, FileSystemEvent Args e)
{

#region WAIT FOR IT TO BE DONE CREATING...
Stream stream = null;
while (true)
{
try
{
if ((stream = File.Open(e.Ful lPath, FileMode.Open, FileAccess.Read ,
FileShare.None) ) != null)
break;
}
catch (IOException ex)
{
System.Threadin g.Thread.Sleep( 1000 );
}
}

if ( stream == null )
throw new ApplicationExce ption("can't open file");

#endregion WAIT FOR IT TO BE DONE CREATING...

//give the output a stream to write to
System.IO.Strea mWriter sw =
new StreamWriter(e. Name.ToString() .Substring(0,e. Name.ToString() .Length-3)
+ "ps");

//DEFINE A NEW PROCESS
System.Diagnost ics.Process procTiff2ps = new
System.Diagnost ics.Process);
System.Diagnost ics.ProcessStar tInfo i = new
System.Diagnost ics.ProcessStar tInfo();

i.FileName = "tiff2ps.ex e";
i.Arguments = e.FullPath.ToSt ring();//"C:\\BizDocs\\V ault\\401.TIF";
i.RedirectStand ardOutput = true;
i.CreateNoWindo w = true;
i.UseShellExecu te = false;
procTiff2ps.Sta rtInfo = i;
}

Help!

//START THE PROCESS
procTiff2ps.Sta rt();

Thats because you are opening and locking it. Why would you open the
file if the command line tool was going to open it.

Ok, I see why OP is opening the file, to check if it is fully created.
But OP have to be sure to close it after that. The change should be:

while (true)
{
using (Stream stream = File.Open(...))
{
if (stream != null)
break;
}
Thread.Sleep(10 00);
}
