Servers Succinctly; [Blog post] 7 ways to compress PDF files in C#, VB. To test this example, run the application and start a prime search. While it s underway, you still can click on other controls, and drag the form around the screen. Of course, to prevent synchronization problems or unintended side effects, you need to make sure your user interface is in a state where only the supported commands are available. For example, the Find Primes button is disabled in this example because we ve chosen to allow only one search at a time. If you like, you can rewrite UpdateForm() method to make it self-sufficient, so that it automatically marshals itself to the user interface thread as needed. This is a common pattern in Windows Forms applications that s easy to implement. private void UpdateForm(TimeSpan timeTaken, string primeList) { if (this.InvokeRequired) { this.Invoke(new UpdateFormDelegate(UpdateForm), new object[] {timeTaken, primeList} ); } else { lblTimeTaken.Text = timeTaken.TotalSeconds.ToString(); txtResults.Text = primeList; cmdFind.Enabled = true; } } Now you can call UpdateFormDelegate() directly. If you call UpdateFormDelegate() from the user interface thread, the code will run ordinarily. If you call it from another thread, the method will call itself on the correct thread, taking care of the marshalling automatically. tesseract ocr pdf c#: [Solved] C# code to extract text from a scanned pdf document ... c# ocr pdf Optical Character Recognition in PDF Using Tesseract Open-Source ...

C#. using System;; using IronOcr;; //.. var Ocr = new AutoOcr(); ...... IronOCR and Tesseract Comparison for . In .NET, there is no general-purpose way to trigger code on specific threads. The Control.Invoke() method is a special exception to this rule that makes writing multithreaded Windows applications much easier. When you call Control.Invoke(), the code checks that the control is created and its Windows handle exists. If its handle exists, the rest of the process is straightforward. The Invoke() method uses the GetWindowThreadProcessId() Win32 API function to find the thread ID for the control, and then compares that value against the currently executing one using GetCurrentThreadId(). This stage determines whether or not marshalling is needed. Life becomes much more ugly if the control s handle isn t created yet. In this case, the Invoke() method walks the control hierarchy trying to find out if the control s parent (or its parent s parent, and so on), have been created yet. If they have, the Invoke() method grabs that thread ID. If you re facing erratic behavior or you think your Control.Invoke() method is taking longer than it should because you re using Invoke() on a control that is created dynamically, you have two possible solutions. You can access the Control.Handle property in your code before you call the Invoke() method, which ensures that the control handle is created. (Of course, you'll need to access Control.Handle from the main application thread.) Or, you can skip directly to the parent by calling the Invoke() method of a container control or the hosting form. c# ocr pdf NuGet Gallery | Pdf.Ocr 4.4.4.1

The keyboard, the gamepad, and the grabbers are connected in addGrabbers() in WrapArmsPad3D. The relevant code fragment is shown here: // in addGrabbers() in WrapArmsPad3D GamePadController gamePad = new GamePadController(); Grabbers grabbers = new Grabbers(. . .); // Grabbers input arguments will be explained later // set up gamepad behavior to catch gamepad input GamePadBehavior gamePadBeh = new GamePadBehavior(grabbers, gamePad); gamePadBeh.setSchedulingBounds(bounds); sceneBG.addChild(gamePadBeh); // set up keyboard controls to catch keyp resses KeyBehavior keyBeh = new KeyBehavior(grabbers); keyBeh.setSchedulingBounds(bounds); sceneBG.addChild(keyBeh); KeyBehavior sends key presses to the grabbers as GrabberOp instances, while GamePadBehavior does the same for gamepad input. Note If you have enough experience with SQL Server, you might want to skip this section and go directly Finally, to marshal your call, Control.Invoke() posts a message to the message queue for the user interface thread (using the Win32 API function PostMessage). As with any other event in a Windows application, this message isn t handled until your application has an idle moment. In other words, if your main thread is tied up with some intensive processing and you use Control.Invoke(), the call may be deferred for some time. Similarly, when your call does execute, it will temporarily take control away from your main thread. For the same reason, make sure that you perform any processor-intensive work on the separate thread before you use Control.Invoke(). For a more detailed look at the implementation behind Control.Invoke(), refer to Justin Rogers's post at http://weblogs.asp.net/justin_rogers/articles/126345.aspx. The technique shown in the previous example works great when you want to perform a single asynchronous task and update the user interface once it completes However, in many situations you ll simply want to take the data that the asynchronous worker provides, and store it somewhere for later use One reason to take this step is to avoid interrupting other work the user is performing For example, consider an application that shows a product catalog in a grid control You might fetch an updated DataSet from a Web service, but you probably don t want to refresh the grid immediately That s because the user might be looking at a specific row, or even performing an edit. tesseract c# pdf The C# OCR Library | Iron Ocr - Iron Software
