BackgroundWorke r - have no idea

[Piotrekk]

Hi
I'am trying to force my background worker to finish, but i can't - its
still visible in windows processes.
have no idea why it's still there when file is sent.
Code is clear and visible so i wish someone could help me.
Thanks
PK

Here is the code:

private void backgroundWorke r1_DoWork(objec t sender,
DoWorkEventArgs e)
{
String location = comboBox1.Text;

IPAddress newAddress = IPAddress.Parse (location);
byte[] fName =
ASCIIEncoding.A SCII.GetBytes(s fName.Substring (sfName.LastInd exOf('\\')
+ 1) + '\0');
FileStream file = null;

TcpClient Client = new TcpClient();
try
{
Client.Connect( newAddress, 5000);
}
catch (Exception ex)
{
MessageBox.Show (ex.Message, "Sender Error",
MessageBoxButto ns.OK, MessageBoxIcon. Error);
}

try
{
if (Client.Connect ed)
{
this.Text = "Sending File";
String line = null;
file = new FileStream(sfNa me, FileMode.Open);
fileLength = file.Length;
Client.Client.S end(fName, 0, fName.Length,
SocketFlags.Non e);

int BytesCount = 0;
mylegth = fileLength / 100;
long i = 0;
this.smoothprog ressBar1.Value = 0;
byte[] buffer = new byte[64];

BytesCount = file.Read(buffe r, 0, 64);
while ((BytesCount != 0))
{
i += Client.Client.S end(buffer, BytesCount,
SocketFlags.Non e);
this.smoothprog ressBar1.Value = (int)((i * 100)
/ fileLength);
BytesCount = file.Read(buffe r, 0, 64);
}
file.Close();
Client.Close();
this.Dispose();
}
}
catch (Exception ex)
{
MessageBox.Show (ex.Message, "Sender Error",
MessageBoxButto ns.OK, MessageBoxIcon. Error);
}
finally
{
file.Close();
Client.Close();
}
}

Not being a great expert on this you may want to confirm but I've had
similar concerns with running Excel from .NET code. I think the system
wants to decide when to terminate the process. I'd start Excel and try to
shut it down when finished, Excel and try to shut it down when finished,
over and over. The system would have 5 or so Excel processes running before
it decided to terminate one. Similar things happen with memory management.
