Microsoft Agent is widely used. We can add it to common applications for use by local systems, or embed it into HTML documents for Internet/Intranet use. Microsoft Agent supports C/C ++, Visual Basic, Java, JScript, VBScript, and other programming languages. It also provides programmers with two programming methods: OLE Automation server and ActiveX control, essentially, both programming methods belong to the scope of OLE technology and are built on the basis of

Using COM-style programming interfacesAssume that you do not use the COM library directly. Do not create your own wrapper. It is more likely that a COM-style programming interface is used. This is due to the fact that many developers now publish applications. Provides the preferred interop assembly (Primary interop Ass

When the unit test requires the CRUD (Create, Retrieve, Update, Delete) operation on the database, a large amount of repeated junk data will be left in our database after the test, these spam are confusing, aren't they? In addition, some errors may occur due to the garbage in our next test. So how should we deal with the junk data and ensure the stability of the test? Obviously, we need to keep the database in the same state before and after each test. In other words, we need "undo" to perform

There are few examples of searching com aggregation on the Internet, either using ATL, simulating ATL, or simulating MFC. Most of them are based on principles. Since the process for querying the iunknown interface is different when you simulate MFC and when you actually use MFC, the method for simulating MFC is different from that for directly deriving from csf-target, there are major differences in the pro
