Specific functions of uses_conversion in ATL ATL: conversion macros are a convenient way to convert various character encodings. They are very useful in function calls. The name of the ATL conversion macro is the [Source Type] 2 [New Type] or [Source Type] 2C [New Type] named according to the following pattern. According to the second form, the macro conversion

When using CString in ATL, you will be prompted to use wtl::cstring, (since WTL also has CString, but is not officially supported, it is best to makeWith the implementation of ATL) and we only need to use atl::cstring, this time only need to add the following 2 sentences in the stdafx.h header file:Note Using atl::cstr

In the VC environment, you can use MFC to create a dialog box. You can also use the ATL class to create a dialog box. The ATL class uses the features of the template class to generate a new class. Next we will introduce this step. First, just like creating a dialog box program in MFC, you need to create a resource file, that is, creating a dialog box resource. This can be completed in VC resource file edi

Chapter II Transformation of one of the simplest window programs I know, there may be a lot of friends on the last chapter of "Hello, world!" The ATL version disagrees because it's not an ATL program-after all, it's just a ccommodule. But anyway, I would say that it almost still has all the components of an ATL GUI program: Portal, initialization, program body,

see the following: Class Atl_no_vtable CPolyCtl: ... public iobjectsafetyimpl in ATL 3.0, the implementation of IObjectSafetyImpl has changed so that it can be used as a template parameter now to provide security options. For example, the class declaration above will appear as Class atl_no_vtable CPolyCtl: ... Public iobjectsafetyimpl and you do not need to rewrite two methods.

Engineering Structure of table ATL File Name Description Projectname. cpp It is the main project file. It contains the support functions required by COM, which are used to provide host files for your components. Projectname. h The interface declaration of the component in the host file. The midl compiler automatically generates the file.The IDL file of the compilation project is used to generate the file.

link of two networks at the same time, when a control calls the imediacontrol: Stop () method twice, it will go to the above breakpoint, and the two entries are respectively the stop () method of the RTP-MP4 filter module in the two controls. This phenomenon should be said that the graph in a control will call the stop () method of the RTP-MP4 filter module in the graph in another control, this is a strange phenomenon, is there any particular emphasis on the delivery of dshow graph messages in

The macro in ATL defines the analysis of offsetofclass, atloffsetofclassRecently, I learned how to use ATL to solve the problem of defining the offsetofclass macro, analyzing the virtual function table by the way, and calling the function through the virtual function table.1. Solve the macro definition of offsetofclass in ATL # define _ ATL_PACKING 8 # define off

[C ++] zlatlcv: Auxiliary library for ATL String Conversion. Can easily convert the UTF-8 string to a string such as TCHAR, zlatlcvtchar Author: zyl910 Today, UTF-8 strings are increasingly used. But in VC, you cannot directly process the UTF-8 string, you have to specifically write UTF-8 and narrow string, wide string, TCHAR String Conversion code. It is not only time-consuming and laborious, but it is easy to cause memory leakage if you do not pay

Component Object Model and ATL implementation Addendum Cheungmine 2007-10-11 The component object model and the ATL implementation document have been written, but a key issue is missing. There is another place where you need to modify the atlcom. h file. I will change it here. Open atlcom0.h after correction in the previous article and find the following function: Stdmethodimp ienumonstlimpl Correct it to

Recently compiled a DLL using ATL, which always appears during compilation."Nafxcwd. Lib (dllmodul. OBJ): Error lnk2005: _ dllmain @ 12..." error!Later, we found that when we created the DLL, we did not use MFC. Later, we added something related to MFC in the project, which caused the above problem.Follow these steps to solve the problem:1. Change the project settings to "dynamic use of MFC"2. on the C ++ settings page, you can see that _ usrdll and _
