I think the issue was by ths following , Unless you explicitly specify otherwise, you are using an SMTP server on the local machine. If so, the application will drop the message in the local SMTP server's outbound queue, and your application's call to Send() will always be successful (if your SMTP server is running and your message is properly formatted). You can set the Outbound Expiration timeout property in the SMTP service to specify how old messages can be before they are dropped from the outbound queue.
LSoft has a nice guide for configuring the SMTP service in IIS 6 for use with their LISTSERV package.

I hope this helps . @Porges' comments explain everything very well:
code :
static void Test(CancellationToken token)
{
    Callback callback = new Callback();

    try
    {
        while (true)
        {
            token.ThrowIfCancellationRequested();

            // for the GC
            GC.Collect(GC.MaxGeneration, GCCollectionMode.Forced);
            GC.WaitForPendingFinalizers();

            Thread.Sleep(100);
        }
    }
    finally
    {
        GC.KeepAlive(callback);     
    }
}
[MethodImpl(MethodImplOptions.NoInlining)]
public static void KeepAlive(object obj)
{
}

I think the issue was by ths following , Could someone help me understand the behavior of node.js export.* variable reference in below scenario? , When you do this:
code :
exports.port = GLOBAL.app_configs.port;
var x = 3;       // assign primitive value 3 to x
var y = x;       // copy the primitive value 3 from x to y
x = 4;           // assign primitive value 4 to x
console.log(x);  // shows 4
console.log(y);  // shows 3

With these it helps Just move install(CODE) into subdirectory (but add this subdirectory at the end ot the script, after others add_subdirectory calls).
I know no other ways to force CMake to execute your installation code after all others.

will help you In your first example, int A; is a tentative definition: a declaration of an identifier at file scope without an initializer and either without a storage class or a static storage class. You can have multiple ones, and they will all refer to the same variable:
The standard says: (ISO/IEC 9899:1999 6.9.2)
