The Itrackcancel interface provides access to properties and methods this determine if a cancellation has been executed by The user and also allows developers to specify what actions constitute a cancellation.

collection table. It is an instance of the fill of the DataSetCommand class. The contents of the DataSet object are based on the XML stream retrieved from the data source by DataSetCommand. I'll cover the DataReader and DataSet in a future column. The data arrives in binary format from the provider to the consumer, and if OLE DB is deployed, it is also passed through a COM configuration. In. NET, the managed provider returns an XML stream. Both providers support query languages (typically SQ
Interop (COM interop) technology. A traditional COM application can invoke a. NET component, while a. NET component (called. NET Assembly in. net) can also invoke a COM component. This very powerful bidirectional interoperability feature allows you to mix two types of technologies in your application. COM + and MTS work in concert with COM components. When you place one. NET component into an MTS package

ComRegisterFunction property and the ComUnregisterFunction attribute, respectively. When COM assemblies are registered as COM interop, Registerfunction is called. Unregisterfunction will be called when the assembly is not registered for COM interop. These features place a necessary key in the registry that allows Excel to know that the class can be used as an Automation add-in.Listing 3-1 A C # class is ca

After reading [C # | Excel] by the farmer's uncle, I accidentally remembered a small project I created two years ago, I have encountered this strange problem that the Excel process cannot end. In fact, the solution is very simple. Excel is a very special thing, all operations on the resource are exclusive, so it is necessary to strictly release the resource. In order to better communicate with you and help those programmers who are being confused, I will attach a small piece of my previous code
