Leadtools.Forms.Ocr Namespace > IOcrEngine Interface : Shutdown Method



The Shutdown Method is available as an add-on to the LEADTOOLS Document and Medical Imaging toolkits.

Shuts down the OCR engine and frees all resources and memory allocated to it.

Syntax

Visual Basic (Declaration) 
Sub Shutdown() 
Visual Basic (Usage)Copy Code
Dim instance As IOcrEngine
 
instance.Shutdown()
C# 
void Shutdown()
C++/CLI 
void Shutdown(); 

Example

For an example, refer to Startup.

Remarks

The Startup method must be called before invoking any other methods or properties in this IOcrEngine.

To check if the engine is started, use the Leadtools.Forms.Ocr.IOcrEngine.IsStarted property.

You must call Leadtools.Forms.Ocr.IOcrEngine.Shutdown to shut down the engine and free the memory and resources used.

You can call the Startup method multiple times, only the first call will start the engine while subsequent calls will only increment an internal counter. You must call Leadtools.Forms.Ocr.IOcrEngine.Shutdown for each Startup called.

The IOcrEngine interface implements System.IDisposable. It is highly recommended that you call System.IDisposable.Dispose (or use the using statement in C# or Using statement in Visual Basic) when creating the IOcrEngine instance. The System.IDisposable.Dispose method will automatically shuts down the engine if it has been started.

Requirements

Target Platforms: Microsoft .NET Framework 2.0, Windows 2000, Windows XP, Windows Server 2003 family, Windows Server 2008 family, Windows Vista, Windows 7
