It can do this because the Listing 13.HandleEvent method is public and therefore can be accessed outside of its containing class. Changing the access modifier on the HandleEvent class to a more restrictive setting would prevent this from happening. c# ean 13 generator Creating EAN-13 Barcodes with C# - CodeProject

The following code uses linq to check the last digit for GTIN barcodes: GTIN-8, GTIN-12 (UPC), ..... I'm aware that the question is in the context of .net/C#. Another approach to events is to use the nongeneric version of EventHandler. This is more like using a delegate in that you have to define the event/delegate type. This approach predates the introduction of generic types in C#, but I have included it because it is still widely used. Listing 10-14 shows the Calculator example implemented without generic support. Listing 10-14. Implementing Events Without Generic Types using System; delegate void CalculationPerformedEventHandler(object sender, CalculationEventArgs args); class CalculationEventArgs : EventArgs { private int x, y, result; public CalculationEventArgs(int num1, int num2, int resultVal) { x = num1; y = num2; result = resultVal; } public int X { get { return x; } } public int Y { get { return y; } } public int Result { get { return result; } } } class Calculator { public event CalculationPerformedEventHandler CalculationPerformedEvent; public int CalculateProduct(int num1, int num2) { // perform the calculation int result = num1 * num2; // publish the event OnCalculationPerformed(new CalculationEventArgs(num1, num2, result)); // return the result return result; } private void OnCalculationPerformed(CalculationEventArgs args) { // make a copy of the event ean 13 check digit calculator c# ean 13 check digit calculator c#: Part III in Visual C# .NET Draw ...

Table 13-1 gives a simpli ed example of a penetration study for a company that sells to several industries. The company has 29,000 customers, roughly divided into four sectors. As you can see, most of the company s sales come from light manufacturing. The companies with the highest lifetime value are in heav y manufacturing. But the high-technology sector is particularly interesting. The U.S. universe comes from Dun & Bradstreet data. It shows the number of companies in the SIC codes that Weldon sells to. As you can see, Weldon s penetration in the high-technology sector is very high: 42 percent. This means that Weldon is a household word in this industry. It will be much easier for Weldon to pick up an additional customer in this sector than in any of the other three because it is so well known there. This shows the power of penetration analysis. Table 13-1 Penetration Analysis "grape", "banana", "pear", "mango" , "persimmon", "lemon", "lime", "coconut", "pineapple", "orange"}; // define a parallel query using method syntax var parallelResults = fruits.AsParallel() .Where(e => e[0] == 'p') .Select(e => new { Name = e, Length = e.Length }); // enumerate the results foreach (var item in parallelResults) { Console.WriteLine("Result - Name: {0}, Length: {1}", item.Name, item.Length); } // wait for input before exiting Console.WriteLine("Press enter to finish"); Console.ReadLine(); } } c# ean 13 generator Calculating EAN-8 / EAN-13 check digits with C# - Softmatic
