Labeling checkTypes for biometric attendance

I have a table named Attendancelogs where I am saving the records that I fetch from a biometric device, the table structure is;
LogType defines the type of log i.e. Biometric/Manual
CheckType defines the type of entry i.e. I or O
VerifyMode defines the type of punch i.e. Fingerprint/Password
isIgnore is used to exclude an entry from the logs.
Now, what I am trying to do is to write a function called sortFunc(); that will process on the already stored records in the Attendancelogs table. what this is suppose to do is;
Mark the checkType of each employee as I for the first entry, then O for their second entry of the date and so on.
If an employee has a last I at the end of the day, meaning no check out, then the next day's first punch of that employee (with in 12 AM - 7 AM) is considered check out for the previous day (marking as a nighter case for that employee) the rest entries are considered as sequential I and O.
any multiple entries within 10 seconds (or defined time) is ignored and marked CheckType as "Auto Ignored for x seconds"
If an employee is not allowed to use Card/Password then his CheckTypes are marked as Card not allowed or Password not allowed
Here is the function that I wrote;
public static bool inn = true;
public void sortLogs(int machineNum)

This did run but it messes up the "12 AM to 7 AM" checks and the password checks, i.e. not the accurate results.
As one of the example seen ^ consecutive O should not be there. I have been going crazy over this!

C# program with COM port going NOT RESPONDING

I have C#/.NET program which uses a COM port and SQL CE Database with a WCF service. Sometimes the program becomes unresponsive (the window freezes) and even in debug mode I cannot the reason.
I can restart the program after restarting my PC or the COM port. The problem isn't with my COM port problem because I have tried it on many PCs and all have the same problem.
How could I resolve this?

C# programs show as NOT RESPONDING whenever there is processing happening in the main UI thread that is preventing UI processing. The general answer here is to push that work into a different thread, so that UI events can continue to process (see references below for more information). In the case of serial ports, the easiest thing to do is hook the SerialPort.DataReceived event instead of polling it: https://msdn.microsoft.com/en-us/library/system.io.ports.serialport.datareceived%28v=vs.110%29.aspx

searching an array for specific criteria and displaying

Hi I am completely new to C# programming and I am getting stuck on my code. My program is to ask the user for a city or zip code, the amount of beds/baths they want, and their price range. I need to to search through my array and then display all the houses that meet their criteria (think Zillow, the website). My code currently displays random houses that do not meet any of the criteria I selected for the home. HELP!

How to prevent stack overflow error in javascript?

I have a javascript function called MakeInput.
It has got approximately 150 lines.
And I have to call that function about 300 times in my code.
My C# code called that function through webbrowser control.
It has to call that function 300 times, until DataTable in C# finishes looping.
But maybe javascript in webbrowser thinks that I am calling an infinite recursive function, so when it comes to about 60 times, it always throws an error called stack overflow at line 38.
How can I prevent this error?
How can I do a long time function in javascript?
EDIT
OK.
I am posting my code.

And the error message was captured.
Sorry, the error message is written in Korean.
But it says, "Stack overflow(at line 38)".
But I think the number is not pointing at the line number, coz I've changed lines but the error message is always 38.

It doesn't think you are in a continuous loop. It fails when memory runs out in stack. The same code might work on a computer with higher memory. Each time a function is called a stack entry is kept in stack to move to calee once the function is done, so in your case the stack space runs out after 60 calls. The line 38 is not line number in your code.
Why dont you try same code on a high end PC

ask for confirmation when checking a box

i currently have a form that has several check boxes, once all the boxes are checked or left empty, it sends it to the database the state of the check boxes
i want to add, if a box is not checked, when you check it, it should ask for confirmation window "you sure you wanna check this"
any help please?
this is the current code
public IMeditor(IMui IMui, IMuser U, string User)
{
InitializeComponent();
this.IMui = IMui;
imu = U;
if (imu.UID == 0)
{
Add.Text = "Add";
imu.name = user;
}
else
Add.Text = "Update";
AuthChat.Checked = imu.AuthChat == 1;
AuthTac1.Checked = imu.AuthTac1 == 1;
AuthTac2.Checked = imu.AuthTac2 == 1;
AuthTac3.Checked = imu.AuthTac3 == 1;
AuthTac4.Checked = imu.AuthTac4 == 1;
AuthTac5.Checked = imu.AuthTac5 == 1;
AuthTac6.Checked = imu.AuthTac6 == 1;
AuthTac7.Checked = imu.AuthTac7 == 1;
AuthTac8.Checked = imu.AuthTac8 == 1;
AuthTac9.Checked = imu.AuthTac9 == 1;
AuthTac10.Checked = imu.AuthTac10 == 1;
switch (imu.Transport.ToLower()) {
case "aim": Transport.SelectedIndex = 0; break;
case "gtalk": Transport.SelectedIndex = 1; break;
case "msn": Transport.SelectedIndex = 2; break;
case "yahoo": Transport.SelectedIndex = 3; break;
}
}

I agree with Izzy. Add something like
private void PrivateInitialize()
{
CheckBox chkBox = new CheckBox();
chkBox.Text = "Click me";
chkBox.CheckedChanged += new EventHandler(chkBox_CheckedChanged);
}
private void chkBox_CheckedChanged(object sender, EventArgs e)
{
MessageBox.Show("Nag, nag, nag! You take out the trash yet?");
}

You need to handle the event CheckedChangedEvent for the checkbox. You can find the sample code on MSDN. Also
this link for the complete understanding of checkbox.
Or else you can derive your own class from CheckBox control of windows forms then override the required function and implement your own logic and create all the checkboxes in your application from this derived class

do it with javascript? add OnClientClick="return confirmCheck(this);"
<script language="javascript">
function confirmCheck(e){
return confirm("are you sure?");
// do other stuff
}
</script>
this should be better than redirecting people
