To try out the BackgroundWorker, it makes sense to use it with the prime-number search example. The first step is to create a custom class that allows you to transmit the input parameters to the BackgroundWorker. When you call BackgroundWorker.RunWorkerAsync(), you can supply any object, which will be delivered to the DoWork event. However, you can supply only a single object, so you need to wrap the to and from numbers into one class, as shown here: public class FindPrimesInput { private int from; public int From { get { return from; } set { from = value; } } private int to; public int To { get { return to; } set { to = value; } } public FindPrimesInput(int from, int to) { From = from; To = to; } } Now, drop a BackgroundWorker component onto your form. When the user clicks the Find Primes button, create a new FindPrimesInput object, and submit it to the worker using the BackgroundWorker.RunWorkerAsync() method, as shown here: // Start the search for primes on another thread. FindPrimesInput input = new FindPrimesInput(from, to); backgroundWorker.RunWorkerAsync(input); Once the BackgroundWorker acquires the thread, it fires the DoWork event. You can handle this event to call the Worker.FindPrimes() method. The DoWork event provides a DoWorkEventArgs object, which is the key ingredient for retrieving and returning information. You retrieve the input object through the DoWorkEventArgs.Argument property, and return the result by setting the DoWorkEventArgs.Result property. tesseract ocr pdf c#: Tesseract OCR C# - YouTube tesseract c# pdf Tesseract ocr PDF as input - Stack Overflow

FindPrimesInput input = (FindPrimesInput)e.Argument; // Start the search for primes and wait. int[] primes = Worker.FindPrimes(input.From, input.To); // Paste the list of primes together into one long string. StringBuilder sb = new StringBuilder(); foreach (int prime in primes) { sb.Append(prime.ToString()); sb.Append(" "); } // Return the result. e.Result = sb.ToString(); } Once the method completes, the BackgroundWorker fires the RunWorkerCompletedEventArgs from the user interface thread. At this point, you can retrieve the result from the RunWorkerCompletedEventArgs.Result property. You can then update the interface and access form-level variables without worry. private void backgroundWorker_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e) { if (e.Error != null) { // An error was thrown by the DoWork event handler. MessageBox.Show(e.Error.Message, "An Error Occurred"); primeList = ""; statusPanel.Text = ""; } else { primeList = (string)e.Result; statusPanel.Text = "Double-click panel to see new prime list."; } cmdFind.Enabled = true; } Notice that you don t need any locking code, and you don t need to use Control.Invoke(). tesseract ocr pdf to text c# Tesseract OCR C# - YouTube

C# tips and tricks 21 - Extracting text ...Duration: 8:48 Posted: Apr 15, 2018 Each planet is a Java 3D Sphere, with a blended material and texture appearance, located at a fixed position in the scene. The planets don t rotate. The OrbitBehavior is attached to the viewing platform in the scene graph s view branch, so is not shown in Figure 8-3. The Background node is an optional component. It ll become useful when the background image is smaller than the canvas, a scenario I discuss in the Some Variations on a Theme section of this chapter. The BackgroundWorker also provides built-in support for tracking progress, which is useful for keeping the client informed about how much work has been completed in a long-running task. Back to the example, setting the Name column as the primary key of the Department table would solve the problem because two departments would not be allowed to have the same name. If Name is the primary key of the Department table, searching for a row with a specific Name will always produce exactly one result if the name exists, or no results if no records have the specified name. To add support for progress, you need to first set the BackgroundWorker WorkerReportsProgress property to true Actually, providing and displaying the progress information is a two-step affair First, the DoWork event handling code needs to call the BackgroundWorkerReportProgress() method and provide an estimated percent complete (from 0 to 100) You can do this as often as you like Every time you call ReportProgress(), the BackgroundWorker fires the ProgressChanged event You can react to this event to read the new progress percentage and update the user interface Because the ProgressChanged event fires from the user interface thread, there s no need to use ControlInvoke() Supporting this pattern in the current example is a little more work Currently, the majority of the work is performed in response to a single method call WorkerFindPrimes() But to provide progress information, you need to call ReportProgress() during the prime search. The WrapPlanets3D()constructor creates the 3D canvas in the standard way and attaches a SimpleUniverse to it: // globals private static final int PWIDTH = 512; private static final int PHEIGHT = 512; private SimpleUniverse su; // size of panel Tip This is common sense, but it has to be said: a primary key column will never accept NULL values. c# ocr pdf NuGet Gallery | Pdf.Ocr 4.4.4.1
