Hi, I am looking forward for some demo example for getting started with scanning multiple pages.

Which should allow :

Scanning a new document,
appending page(s) to an existing document,
removing selected page from the existing document,
replacing page(s) with newly scanned page(s) from the existing document.

Please help, thanks

Arash,
To scan you should do the following:
1)  Use TwainSession.SelectSource to select the scanner driver
2) Use TwainSession.Aquire to scan the images
3) Handle the aquirepage event to receive the scanned images and save them to disk using RasterCodecs.Save.

Also, please take a look at our scanning tutorials that are in our help files installed with the toolkit and see "Acquiring an Image" tutorial.

Aarsh,
From a different thread, we know you want this done in a console application. However, for Twain features to work, you must have a valid Window object in your project, because this is a Twain requirement.

As a minimum, you must create a window and make it hidden in your console application. This means you don't need to display it, but you will need it anyway.

I acquired a sample project from my colleague that does this. Please see attached project.

Aarsh,
The attached project is very simple. Please open it and take a look at it.
However, the steps are:
1) Create a console application.
2) Add a Form.
3) Declare a TwainSession object inside the form.
4) Declare an object from the form.
5) Use the form object to call the Twain functions like acquire, select source..etc.
