From Eye 'tracing' and 'tacking' the eye I may safely assume you're asking for a eye tracking algorithm.

Do you know CodeProject has an article search engine [^]?

But, let me do more for you...[^].

Use the FormClosing of your main form. It's EventArgs will tell you the reason;

Being one of these;
* ApplicationExitCall
* FormOwnerClosing
* MdiFormClosing
* TaskManagerClosing
* UserClosing
* WindowsShutDown

Enjoy Smile | :)

Yes. Use the above if you are using a windows app
Use "AppDomain.CurrentDomain.ProcessExit" event otherwise. which will get called on th eprocess exit.. This is for the full appdomain

The task-manager just sends messages to the application, and if it doesn't proces them it 'assumes' that the application is dead.

I doubt that the taskmanager gets the exit-reason of each application.

hi,

I am working on a door lock system. i want to read data from each reader.
if coming data is valid card no. then i have to give 'Gy'[G is address of reader] command to that particular reader. i am using axWinsock1 component and using timer control to read data from
reader . it continuously reading from 'G' reader.

private void timer1_Tick(object sender, EventArgs e)
{
lbl_time.Text = System.DateTime.Now.ToString();
try
{
string cmd = "G0";
byte[] msg = Encoding.ASCII.GetBytes(cmd.ToString());
axWinsock1.SendData(msg);
Object objData = new System.Object();
axWinsock1.GetData(ref objData, 8, 1024);
string strData = (string)objData;
if (strData.Trim() != "0")
{
timer1.Enabled = false;
txtDataRx.Text = txtDataRx.Text + "Input Time : "+ System.DateTime.Now.ToString();
txtDataRx.Text = txtDataRx.Text + " Card No. : "+ strData;
cmd = "Gy";
msg = Encoding.ASCII.GetBytes(cmd.ToString());
axWinsock1.SendData(msg);
axWinsock1.SendData(msg1);
txtDataRx.Text = txtDataRx.Text + "Door Open";
timer1.Enabled = true;
}
}
catch(Exception se)
{
//MessageBox.Show ( );
string msg = se.ToString();
}

}

I try these code, but doesn't work,

            string file = @"e:\test.log";<br />
<br />
            FileStream fs1 = new FileStream(file, FileMode.Append, FileAccess.Write, FileShare.Read);<br />
            FileStream fs2 = new FileStream(file, FileMode.Open, FileAccess.Read);            <br />

throw an exception:

System.IO.IOException: The process cannot access the file 'e:\test.log' because it is being used by another process..

how to solve this?

Glad to discuss with you and best wishes.

Sorry for my mistake, i create a test project like the first message, and it works.
but in my real project, it always throw the exception...

I wrote a singleton mode class, Logger class, to write log to file.
This logger class has 'LogLevel' property, the actions like in log4net.
then, i wrote a unit test class to test its LogLevel property setting will work.
...
I use the first FileStream in Logger class, then
I use the second FileStream in Logger Unit Test class, to check log message is corrent.
...
the second FileStream always throw that exception.
Frown | :(

thanks, i fixed it with your help.

i debug the code very carefully, find the exception was throw by next sentence.

StreamReader reader = new StreamReader(fileStream);

but not new FileStream(), so i changed StreamReader to fileStream.GetByte(..)
then it works.

Console application in intranet

Hi,

I have a console application to convert XML to HTML through XSLT.
When I try to execute this exe from server (intranet) I encound the following exception:

Request for the permission of type 'System.Security.Permissions.FileIOPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed..

Please advice.

Thanks,

Are you running the application from a network share ? It seems to be fixed in .Net 3.5 SP1. In previous versions it would crash if ran from a share due to the default low trust behavior.
