This time I was thinking about how to use a small program with COM components. I suddenly remembered why I used com during the last interview, instead of using a common DLL? After checking it on Google, many people also asked the same question: using COM to write a program is more troublesome than using a common DLL, but it brings a lot of benefits, especially wh

First create a COM component, insert a dual interface ITest, and implement the following three methods on this interface:STDMETHODIMP ctest::test (void) //No input/output parameter { //TODO: Add implementation code in this MessageBox (null,l "test", L "test", MB_OK); return S_OK;} STDMETHODIMP Ctest::test1 (BSTR A1) //have a string input parameter { //TODO: Add implementation code in this MessageBox (null,a1,l "test", MB_OK);

COM component is actually a special object system, follow a unified standard, so that each software can access the object in some way, can do component calls. COM is the unified standard-invoking COM components through interfaces. An interface is the only thing that a
If you are an active Server page (ASP) developer, it is believed that you may often use COM objects to create ASP pages. Even when you use it, you ignore that he is a COM object. For example: ADO. The only component with the highest call rate is the ability to extend unlimited functionality to your page. However, the ASP itself is an interpretative script that is not functional enough to

The current project is to develop an add-on for Excel to achieve financial-related business, and after a lot of factors are considered, decide to abandon C # and develop it in C + +. There are two ways to develop Excel add-ins in C + +, one is an Excel add-in XLL, and the other is to use ATL to make COM add-ins. The advantage of the XLL approach is that it is close to the bottom of Excel, executes quickly, and does not need to modify the registry, but
Using WMI to obtain system information procedures
As an example of obtaining a native system, the process of obtaining system information is as follows:
1 initialization of the COM library
Since the WMI application was written in C + + based on COM technology, the COM library must be initialized, when the call function CoInitializeEx is used to initialize the
The Oracle tutorial you are looking at is that Oracle uses Pl/sql to manipulate COM objects. The Pl/sql is extended by Oracle company to standard SQL, dedicated to programming in Oracle databases, and is a third-generation process programming language. Starting from Oracle8, it provides the process of calling external C language directly from Pl/sql, allowing developers to use PL/SQL for programming modules in C language. Starting with Oracle8i, Java

Introduction
How to call
When using COM components, it is common practice to call CoInitialize (NULL) at the front of the main function, and the last face to invoke CoUninitialize ();One problem today is that the use of COM components in a thread fails, and I suspect that COM also needs to be initialized in threads. That is, the initialization of COM
