Re: C# barcode decoding library - C# Discussion Boards - CodeProject
I know GS1-128 and also EPC and I worked with barcodes (as part of a project for warehouse management) - those are standards made for the paper mostly.

Figure 7-8 Workflow exceptions for the Sequential workflow Execute the workflow again The First Activity message appears, then the General Fault Error message appears When the Throw activity is encountered, the Fault Handler is triggered The first Fault Handler is for Workflow Terminated, but the workflow was not terminated by the Throw activity, so the next Fault Handler is triggered The next Fault Handler is the Exception Fault Handler, which is the catch-all Therefore, it s triggered, and the message box appears If you choose to, you can create your own exception class that defines an exception within your application and use that exception as the Fault Type for a Fault Handler When you view the list of exceptions from which to choose, the common thread is that they re all of type Exception So, you can create a class that inherits from System.

Our new Process function first iterates the processes and calls on the QuickCheck delegate (if it is not null) to see if all is OK. As soon as one of these checks returns false, we return from the method and do no further work. Otherwise, we iterate through the processes again and call the Action delegate. What type is a Check We need a delegate to a method that returns a Boolean and takes a Document:

delegate bool Check(Document doc);

Summary

We call this type of check method a predicate: a function that operates on a set of parameters and returns either true or false for a given input. As you might expect,

given the way things have been going so far, this is a sufficiently useful idea for it to appear in the framework (again, as of .NET 3.5).

In this chapter, we looked at three important tasks that provide advanced security for your CentOS server. Specifically, we looked at how to generate and use digital certificates to secure TCP connections with TLS. We also looked at using the RPM and AIDE tools to monitor the disk for unauthorized changes, as well as how to use netfilter to monitor the network for connection attempts. Finally, we looked at the core aspects of running SELinux such as selecting the mode, the importance of context information, and how to maintain it. In the next chapter, we will take an in-depth look at netfilter and how to build an advanced firewall. We will also look at restricting network services using tcp_wrappers and setting up a central log server.

The previous examples have all turned exactly one piece of information into a single string (or vice versa). Very often, though, we need to compose multiple pieces of information into our final output string, with different conversions for each part. We could do that by composing strings (something we ll look at later in this chapter), but it is often more convenient to use a helper method: String.Format. Example 10-44 shows a basic example.

int val1 = 32; double val2 = 123.457; DateTime val3 = new DateTime(1999, 11, 1, 17, 22, 25); string formattedString = String.Format("Val1: {0}, Val2: {1}, Val3: {2}", val1, val2, val3); Console.WriteLine(formattedString);
