Observe the Allow Nulls column in the design window of the Department table some fields have this check box checked, but others don t. If the check box is checked, the column is allowed to store the NULL value. The best and shortest definition for NULL is undefined. In your Department table, only DepartmentID and Name are required, so Description is optional meaning that you are allowed to add a new department without supplying a description for it. If you add a new row of data without supplying a value for columns that allow nulls, NULL is automatically supplied for them. Especially for character data, a subtle difference exists between the NULL value and an empty value. If you add a product with an empty string for its description, this means that you actually set a value for its description; it s an empty string, not an undefined (NULL) value. The primary key field never allows NULL values. For the other columns, it s up to you to decide which fields are required and which are not. In some cases, instead of allowing NULLs, you ll prefer to specify default values. This way, if the value is unspecified when creating a new row, it will be supplied with the default value. The default value can be a literal value (such as 0 for a Salary column or "Unknown" for a Description column), or it can be a system value (such as the GETDATE function, which returns the current date). c# ocr pdf to text: Welcome to the Tesseract.Net SDK - Tesseract OCR - Patagames.com tesseract ocr pdf to text c# The C# OCR Library | Iron Ocr - Iron Software

A major benefit of rendering the background using a subclass of Canvas3D is that the image is a BufferedImage rather than a Java 3D Background node. This makes it easier to apply Java 2D effects to the image at runtime, such as rotation, fading, scaling, and various color adjustments. In this section, I describe how to rotate the background image. Figure 8-9 shows two screenshots of the SpinPlanets3D application taken a few seconds apart.

It's COM, so calling it from C# via interop is also doable and pretty simple: ... Layout.Text ' this puts the ocr results into a string Next File. Because the Thread class supports only methods with no parameters and no return value, it s common to put the code you want to execute in a separate class. You can then add properties to that class for the input and output information. A common design in .NET applications is to create a Worker class that encapsulates the code for performing your specific task and the thread object. That way, you don t need to track both the worker and the thread objects separately. Before you create your thread wrapper, it makes good sense to factor out all the threading essentials into a base class. That way you can use the same pattern to create multiple asynchronous tasks without recoding it each time. This approach also gives you the benefit of defining a standard interface. We ll examine the ThreadWrapper base class piece by piece. First of all, the ThreadWrapper is declared abstract so that it can t be instantiated on its own. Instead, you need to create a derived class. public abstract class ThreadWrapper { ... } c# ocr pdf to text Optical Character Recognition in PDF Using Tesseract Open-Source ...

Apr 15, 2018 · C# tips and tricks 21 - Extracting text from an image using Tesseract OCR library for C# (CSharp ...Duration: 8:48 Posted: Apr 15, 2018 Identity columns are auto-numbered columns. This behavior is similar to AutoNumber columns in Microsoft Access. When a column is set as an identity column, SQL Server automatically provides values for it when inserting new records into the table; by default, the database doesn t permit manually specified values for identity columns. SQL Server guarantees that the generated values are always unique, which makes them especially useful when used in conjunction with the PRIMARY KEY constraint. You already know that primary keys are used on columns that uniquely identify each row of a table. If you set a Figure 8-9. The whirlpool of space (Source: NASA/JPL-Caltech) The background image is rotated around its center by 2 degrees in a clockwise direction every 200 ms. The image is drawn onto the canvas so its center is located at the canvas s center. The class diagrams for SpinPlanets3D are shown in Figure 8-10; only the public methods are listed. The ThreadWrapper defines two public properties. Status returns one of three values from an enumeration (Unstarted, InProgress, or Completed). ID returns an automatically generated unique ID, which is useful for tracking the task when several are underway at once. // Track the status of the task. private StatusState status = StatusState.Unstarted; public StatusState Status { get { return status; } } // Use a unique ID to track the task later, if needed. private Guid id = Guid.NewGuid(); public Guid ID { get { return id; } } The ThreadWrapper wraps a Thread object. It exposes a public Start() method which, when called, creates the thread and starts it off: // This is the thread where the task is carried out. private Thread thread; // Start the new operation. public void Start() { if (status == StatusState.InProgress) { throw new InvalidOperationException("Already in progress."); } else { // Initialize the new task. status = StatusState.InProgress; // Create the thread and run it in the background, // so it will terminate automatically if the application ends. thread = new Thread(StartTaskAsync); thread.IsBackground = true; // Start the thread. thread.Start(); } } The thread executes a private method named StartTaskAsync(). This method farms the work out to two other methods DoTask() and OnCompleted(). DoTask() performs the actual work (calculating the prime-numbers). OnCompleted() fires a completion event or triggers a tesseract ocr pdf c# How to use OCR to extract text from PDF in ASP.NET, C#, C++, VB ...
