Example

Remarks

This method should be called before calling any other method in LEADTOOLS WIA toolkit. Likewise, when the handle to the WIA session is no longer needed, it should be ended by calling Leadtools.Wia.WiaSession.Shutdown method. For every call to Startup there must be a call to Leadtools.Wia.WiaSession.Shutdown.

Call the WiaSession.IsAvailable method to determine whether a WIA source with the specified version is installed.

Note:

You do not need to call Startup if you are using the high-level WiaSession.AcquireSimple method, since it handles session initialization, session end, and device selection automatically.

For more information, refer to Initializing a WIA Session.

For more information, refer to Freeing the WIA Session.

Requirements

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