of the model board class are carefully used. The core of ATL is constructed by dozens of model board classes, by researching the source code of ATL, we can recognize the usage of the model board class more comprehensively. ---- The same as the model board, the multi-inheritance technique is an extremely controversial Technique in the C ++ language. Multiple inheritance techniques can be used to make the de

Introduction to ATL (1) As ATL/COM/ActiveXI would like to improve the popularity of our forum and write some articles to attract more com users.Newbie. Every day, you will see some problems that new users encounter when passing parameters, such as custom structure types, arrays, interfaces, and other parameter types. This article mainly makes some fear of COMNewbie knows what basic knowledge to master

Microsoft Corporation provides the latest data development technology for OLE DB, which is built on COM interfaces. Because the OLE DB development database is convenient and fast to database access, it is a preferred technology for many commercial software. As a programmer, I was fortunate to participate in the development of interactive TV programs of Chengdu World Video Network Limited liability company. In the development of "stock on demand" system, we chose the

The latest data development technology ole db provided by Microsoft is built on the COM interface. Because ole db is very convenient to develop databases and has fast access to databases, it has become the preferred technology for many commercial software. As a programmer, I have the honor to participate in the development of interactive TV programs of Chengdu World video network Co., Ltd. In the development of the "stock on-demand" system, we chose the ole db class encapsulated by

ATL, Active Template Library Activity Template Library, is a type of Microsoft Program Library, supports the use of C ++ language to write ASP Code And other ActiveX programs. Through the Active Template Library, you can create COM components and then call COM objects through scripts on the ASP page. Such COM components can contain properties pages, dialog boxes, and other controls. ATL is undoubtedly th

STL (standard template library STL) is a general term for a series of software developed by the HP lab. It was developed by Alexander Stepanov, Meng Lee, and David R musser while working at the HP lab. Although it mainly appears in C ++, this technology has existed for a long time before it was introduced into C ++. STL code is broadly divided into three types: algorithm (algorithm), container (container), and iterator (iterator ), almost all code uses the template class and template function, w

　　ATL can be used as a complete control development framework. Its main goal is to provide convenient development methods and generate smaller target files. Because ATL can be removed from MFC, its execution speed and loading speed are faster than those developed by MFC. Of course, you can also use MFC in ATL, but this will lose the advantages of

M_pfncreateinstance (punkouter, riid, ppvobj); now everything is clear, The layer-by-layer packaging of ATL for creating class factories has been opened, and the rest of the process for creating components is already We are very familiar with the process! However, we still need to query an iunknown pointer for the class factory object. We can see in the previous pentry-> PCF. 6: stdmethod (QueryInterface) (refiid IID, void ** ppvobject){Return _ int

Http://www.vckbase.com/document/viewdoc? Id = 211 IntroductionThe purpose of this tutorial is to show you how to use ATL to create a COM server and use visual c ++ and Visual Basic programs to call this server separately. I don't want to go deep into the details of COM, and I don't want you to get stuck in IDL. This tutorial was designed only for novice programmers of VC ++. It tells them how simple it is to create a COM Object using

But this is explained in Vc.net 2003 under the use of the method, even if you no longer use vc6.0, also please and the previous content, reference.2, this first component, in addition to all the COM components must be IUnknown interface, we implement a self-defined interface Ifun, it has two functions: Add () to complete the addition of two numbe

Download source code I. Preface 1. It is basically consistent with the content in COM Component Design and Application (5. However, this article explains how to use it in vc.net 2003. Even if you no longer use vc6.0, compare it with the previous one.2. Except for the iunknown interfaces required by all COM components, the first component implements a self-defined interface ifun, which has two functions: add () completes the addition of two values, and CAT () completes the connection between the

Reprinted: In www.csdn.net, due to the needs of the ATL server, it is necessary to decode the address, command, and other complex text field information sent from the client, and the regular expression is recognized as the most powerful text parsing tool, therefore, ATL provides some libraries for regular expressions to facilitate our work.

First, I declare that I am not a master of COM/ATL. Although I have been in contact with them for four years, I have not been able to conduct in-depth research and use them extensively for some reasons at work. However, it is a bit difficult to look back at their painful experiences. Here, I would like to share with you how to learn them, so as to reduce the detours for later users. I personally think it is not easy to learn com. Only by understanding

the a2w macro was being used. I think this was probably just good fortune rather than vc7 being exceptionally helpful (no pun intended !). So: Don't use uses_conversion and friends in thread functions or tight loops-you have been warned! ========================================================== ================== ATL string: What's wrong with the uses_conversion Macros? How to avoid using them? Q:ATL string: What's wrong with the uses_conversion

If you are using vc.net (ATL 7.0), please read the next article. (Of course, reading this article is also good)4. Except for the iunknown interfaces required by all COM components, the first component implements a self-defined interface

ATL is used to write COM programs,The CLR is the common language runtime for. Net.MFC refers to the MFC class Library, MFC programs are made with these class libraries,WIN32 routine is not MFC, using the API function of the program.MFC, ATL, and the CLR are the 3 largest libraries built into VC2005, covering a variety of Windows development methods and development applications. Of course there are more than

ATL 7.0 introduces some of the new transformation classes and macros that provide important improvements to existing macros.The new string conversion class and name macro form: C Source type 2[c] target type [EX]which• The source type and target type are described in the following table.[c] is the target type must be read-only.[ex] is the initial size of the buffer that must be specified as a template parameter.

Chapter 2 transformation of a simplest window Program I know, there may be many friends on the "Hello, world!" Chapter !" The ATL version does not agree, because it is not an ATL Program-after all, it only has a ccommodule. However, I still want to say that it still has almost all the components of an ATL GUI program: entry, initialization, program body, uninstal

3. For com_interface_entry_tear_off (IID, x), refer to the ATL routines beeper and commap. The purpose of using this macro is to put some rarely used interfaces in a single component for implementation.This component is created only when this interface is found, and is released when its reference count is reduced to 0. MeWe know that components in ATL are implemented through multi-inheritance. Every time a

MFC, ATL, and CLR are the three built-in libraries of vc2005, covering various development methods and applications of windows. Of course, there are more than three libraries for C ++ development, but these three are recommended by Microsoft. From the programming level, Win32 is the lowest layer, followed by MFC. Then the CLR. Win32 winapi MFC class library CLR. Net Library 1. Generally, Win32 does not use MFC. It is compiled using API functions.Pro
