USING THE SHAREPOINT DESIGNER in Word

Generator gs1 datamatrix barcode in Word USING THE SHAREPOINT DESIGNER

Can C++ source code be compiled to managed code Can source code use native types Can generated object files be linked with native object files to produce a mixed-code assembly Can managed code in the resulting assembly be verifiably type safe (Required if assembly should execute with restricted .NET permissions) Can the resulting assembly be loaded from a network share Yes Yes Yes

elapsed time, the StopWatch class records the counter value when you call the Start method and deducts the number from the counter value when you call the Stop method. Different system counters are incremented at different frequencies, so the number of elapsed ticks has to be divided by the frequency to get the time in seconds. You can use the members of the StopWatch class to work with the tick counter directly, as Listing 22-2 shows. Listing 22-2. Using Ticks Directly to Measure Time using System; using System.Diagnostics; class Listing 02 { static void Main(string[] args) { // print out details of the timing resolution and frequency Console.WriteLine("Frequency: {0}", Stopwatch.Frequency); Console.WriteLine("High Resolution: {0}", Stopwatch.IsHighResolution); // get the tick value long initialCounterValue = Stopwatch.GetTimestamp(); // perform the task we want to measure long total = 0; for (int i = 0; i < int.MaxValue; i++) { total += i; } // get the tick value again long finalCounterValue = Stopwatch.GetTimestamp(); // get the elapsed number of ticks by deducting the // initial value from the final value long elapsedCount = finalCounterValue - initialCounterValue; // work out how many milliseconds have elapsed by using the // counter frequency float milliSecondsElapsed = (elapsedCount / ((float)Stopwatch.Frequency)) * 1000; Console.WriteLine("Operation took: {0:F0}ms", milliSecondsElapsed); // wait for input before exiting Console.WriteLine("Press enter to finish"); Console.ReadLine(); } } The first thing that Listing 22-2 does is write the frequency and resolution information for the current system to the console. The static GetTimestamp method is used to get the counter value before and after the operation you want to time (which is adding together the positive int values again). You can then use the counter frequency information to work out how the number of counter ticks relates to
