I am talk about FormClosing code (many days) not your reply, because i do not understand it. and i know this is my problem.
A general advice, the answers must be depend on who asking, if he beginner or advanced..

Ok. i tried many times, and if i can doing it with my self, i did not ask here. now i gave up. thank you again.

where i put this code? Complete it Please..

Thanks for your reply, can you give me an example code? sorry, i am beginner.

Thank you, but Form1 must be like Main form. i think this is not the problem in this case.

Visual C# 2015.
Ok. really thank you again for all answers...

Button must be not enable if all checkboxes unchecked not one.
Sorry! what is (cb) in your code (c is CheckBox cb)? it show error..

Yes. All CheckBoxes and button in the same Panel.

1) Yes. when unchecked one and other checked, the button not enable. but it must be enable as long as other checked.
2) Yes. but not all like this case.

Thank you for your answer. but in all cases when unchecked one of CheckBoxes, the button become not enable. despite of another CheckBokes still checked!
and about second question, can you give me an example to do that?

Thank you a lot. Then what about Windows Activation? it take time also, and that is the code:

public static bool IsWindowsActivated()
{
ManagementScope scope = new ManagementScope(@"\\" + System.Environment.MachineName + @"\root\cimv2");
scope.Connect();

SelectQuery searchQuery = new SelectQuery("SELECT * FROM SoftwareLicensingProduct WHERE ApplicationID = '55c92734-d682-4d71-983e-d6ec3f16059f' and LicenseStatus = 1");
ManagementObjectSearcher searcherObj = new ManagementObjectSearcher(scope, searchQuery);

using (ManagementObjectCollection obj = searcherObj.Get())
{
return obj.Count > 0;
}
}

When open Form2 it take time to show. and that is what in Form2 Load:

labelMemory.Text = GetPhysicalMemory();


public static string GetPhysicalMemory()
{
ManagementScope oMs = new ManagementScope();
ObjectQuery oQuery = new ObjectQuery("SELECT Capacity FROM Win32_PhysicalMemory");
ManagementObjectSearcher oSearcher = new ManagementObjectSearcher(oMs, oQuery);
ManagementObjectCollection oCollection = oSearcher.Get();

long MemSize = 0;
long mCap = 0;

foreach (ManagementObject obj in oCollection)
{
mCap = Convert.ToInt64(obj["Capacity"]);
MemSize += mCap;
}
MemSize = (MemSize / 1024 / 1024) / 1024;
return MemSize.ToString() + " GB";
}

Thank you, but unfortunately all this did not help me.

Really Thank you for your solution, it helped me except changing [INNER JOIN emp_job] to [INNER JOIN jobs].
The design in this project like this, because it must be one manager for each department. but your opinion is right in case if manager changed, so i will try to do your first advice. thanks alot again.

Thank you for your solution. i will learn it because i am beginner in SQL, but in this case what is the query, emp and mgr in one table?

Simply, i want every employee take a code depend on his department in company, like HR_001, HR_002... or Sls_001, Sls_002... all this in one column (emp_Code) from department abbreviation name (dept_ShortName) and add one number (+1) each new employee.
