The first step is to set the BackgroundWorker.WorkerSupportsCancellation property to true. To request a cancellation, your form needs to call the BackgroundWorker.CancelAsync() method. In this example, the cancellation is requested when a Cancel button is clicked: Table 4-1.

Instead, the code that s performing the task needs to explicitly check for the cancel request, perform any required cleanup, and return. Here s how you can add this code to the FindPrimes() method so that it checks just before it reports progress: for (int i = 0; i < list.Length; i++) { ... if ((i % iteration) && (backgroundWorker != null)) { if (backgroundWorker.CancellationPending) { // Return without doing any more work. return; } if (backgroundWorker.WorkerReportsProgress) { backgroundWorker.ReportProgress(i / iteration); } } } The code in the DoWork event handler also needs to explicitly set the DoWorkEventArgs.Cancel property to true to complete the cancellation. You can then return from that method without attempting to build up the string of primes. private void backgroundWorker_DoWork(object sender, DoWorkEventArgs e) { FindPrimesInput input = (FindPrimesInput)e.Argument; int[] primes = Worker.FindPrimes(input.From, input.To, backgroundWorker); if (backgroundWorker.CancellationPending) { e.Cancel = true; return; } // (Code for building the prime list.) } add watermark to pdf c#: Using iTextSharp To Watermark /Write Text To Existing PDF's ... tesseract c# pdf How to use OCR to extract text from PDF in ASP.NET, C#, C++, VB ...

Stores a numerical Globally Unique Identifier (GUID) A GUID is guaranteed to be unique; this property makes it very useful in certain situations In this book, we prefer to generate unique identifiers using other methods, but it s good to know there are options Stores variable-length character data NVarChar stores Unicode data with a maximum length of 4,000 characters, and VarChar stores non-Unicode data with a maximum length of 8,000 characters This data type is best used for storing short strings (note their length limitations) without fixed lengths Stores fixed-length character data Values shorter than the declared size are padded with spaces NChar is the Unicode version and goes to a maximum of 4,000 characters, whereas Char can store 8,000 characters When the size of the strings to be stored is fixed, it s more efficient to use Char than VarChar Stores large character data. tesseract c# pdf Optical Character Recognition in PDF Using Tesseract Open-Source ...

At this point, you can check if the task was canceled, and handle it accordingly. private void backgroundWorker_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e) { primeList = ""; statusPanel.Text = ""; if (e.Cancelled) { MessageBox.Show("Search cancelled."); } else if (e.Error != null) { MessageBox.Show(e.Error.Message, "An Error Occurred"); } else { primeList = (string)e.Result; statusPanel.Text = "Double-click panel to see new prime list."; } cmdFind.Enabled = true; } Now the BackgroundWorker component allows you to start a search and end it prematurely. If Planets3D is called with sun.gif as the background image, the scene is displayed as shown in Figure 8-5. At first, the BackgroundWorker component seems like the perfect solution to building multithreaded applications, and in many cases it is. The BackgroundWorker component makes particularly good sense when you have a single long-running task that executes in the background. But the BackgroundWorker doesn t provide some features, such as the following: The ability to manage multiple asynchronous tasks at once. For example, you can t run multiple prime-number queries at once (at least not without some ugly workarounds). The ability to communicate in ways other than sending a progress report or cancellation request. For example, you can t pause an in-progress task or supply new information. You re limited to the features baked into the BackgroundWorker. The ability to directly access and manipulate details about the background thread (such as its priority). If you re creating an application that needs these features, you need to step up to the System.Threading.Thread class. The Thread class represents a new thread of execution. To use the Thread class, you begin by creating a new Thread object, at which point you supply a delegate to the method you want to invoke asynchronously.
