Stopping execution of process in C# windows application. How can I stop the form from doing whatever it is doing without closing the whole application? The 'Stop' button would have to stop a process that's being run in another class. But you normally flag something on it that tells it you want it to stop. Class Program static void. In C, you can exit a program in these ways: Call the exit function. Call the abort function. Execute a return statement from main. Exit function.

By convention, a return code of zero means that the program completed.

exit function
The exit function, declared in <stdlib.h>, terminates a C++ program. The value supplied as an argument to
exit
is returned to the operating system as the program's return code or exit code. By convention, a return code of zero means that the program completed successfully. You can use the constants EXIT_FAILURE and EXIT_SUCCESS, also defined in <stdlib.h>, to indicate success or failure of your program.Issuing a return statement from the
main
function is equivalent to calling the exit
function with the return value as its argument.abort function
The abort function, also declared in the standard include file <stdlib.h>, terminates a C++ program. The difference between
exit
and abort
is that exit
allows the C++ run-time termination processing to take place (global object destructors will be called), whereas abort
terminates the program immediately. The abort
function bypasses the normal destruction process for initialized global static objects. It also bypasses any special processing that was specified using the atexit function.atexit function
Use the atexit function to specify actions that execute prior to program termination. No global static objects initialized prior to the call to atexit are destroyed prior to execution of the exit-processing function.
return statement in main
Issuing a return statement from
main
is functionally equivalent to calling the exit
function. Consider the following example:The
exit
and return statements in the preceding example are functionally identical. However, C++ requires that functions that have return types other than void return a value. The return statement allows you to return a value from main
.Destruction of static objects
When you call
exit
or execute a return statement from main
, static objects are destroyed in the reverse order of their initialization (after the call to atexit
if one exists). The following example shows how such initialization and cleanup works.Example
In the following example, the static objects
sd1
and sd2
are created and initialized before entry to main
. After this program terminates using the return statement, first sd2
is destroyed and then sd1
. The destructor for the ShowData
class closes the files associated with these static objects.Another way to write this code is to declare the
ShowData
objects with block scope, allowing them to be destroyed when they go out of scope:See also

Within main, finish the program with return 0;
std::string isShutdown;
std::cout << 'Shutdown? Y/N' << std::endl;
std::cin >> isShutdown;
std::cin >> isShutdown;
if (isShutdown 'Y')
{ return 0;}
{ return 0;}
You can also end a program by using abort() and exit(), but they place additional responsibilities on the conscientious programmer. Using return is the standard way.
