Start Visual Basic and create a new Standard EXE project. See the steps below on how to add the reference. For this sample, you will need to add a reference to the type library for Excel before you can run the code. In Visual Basic, this is done through the References dialog box found under the Project | References menu. To early bind to an Automation server, you need to set a reference to that server's type library. This sample uses early binding, which is considered better in most cases because it affords greater performance and better type safety. With early binding, your application knows at design-time the exact type of object it will be communicating with, and can declare its objects as a specific type. With late binding, methods are not bound until run-time and the Automation server is declared as Object. There are two ways to control an Automation server: by using either late binding or early binding. This article demonstrates how to create and manipulate Excel by using Automation from Visual Basic.
