is your file is present int the 3 folder??
if not then you must first transfer you files to the 3 folder...
otherwise compile your file from within the folder where it do exists..

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...[^].

hi,
how i can know if the process die normally or abnormally in c#(if there is boolean variable in c# to it)?
|
|
|
|
|
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

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
|
|

|
|
i'm writing a c# code similar to the windows task manager, and i need to konow if each process in it closed normally or not, how i can do this in c#?
|
|
|
|
|
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,![Rose | [Rose]](https://www.codeproject.com/script/Forums/Images/rose.gif)
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();
}
}
HOW I IMPLEMENT THIS FOR MORE THEN ONE READER ?

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.
Glad to discuss with you and best wishes.
