1, DLL view and debugging The core functionality of the Windows operating system is implemented in a modular way. It places a variety of related functions in the same DLL module. Therefore, each application invokes the associated system or user-defined DLL. Therefore, when you write a program, you must know how to view and debug the

DLL (Dynamic Link Libraries) topics: Large applicationsProgramThese modules are composed of many modules that complete relatively independent functions and work together to complete the work of the entire software system. Some modules may have common functions and will still be used when constructing other software systems. When constructing a software systemSource codeIf all files are statically compiled into the entire application EXE file, some p

Some modules may have common functions and will still be used when constructing other software systems.

Recently done in the Windows XP x64,vs2005 environment to do 32-bit programs to compile the work of 64-bit programs, encountered some of the 64-bit programming may encounter problems: such as inline assembly (the solution is changed to C + + code), a long type of change, The most critical issue is encountering a 64-bit process that requires calling a 32-bit DLL. Because some 32-bit DLLs do not have source code, can not be recompiled to a 64-bit

There are two ways that an application can use a DLL: One is an implicit link, the other is an explicit link. Before you use a DLL, you should first know the structure information of the functions in the DLL. Visual c++6.0 provides a small program named Dumpbin.exe in the Vc/bin directory that lets you view the function structure in a

You should also switch resources when exporting functions in an MFC extension DLL. In a shared (dynamically linked) MFC rule DLL, before each of the exported functions need to switch resources, in the extension DLL also need, because they are dynamically linked to the MFC library, in the call to export functions, to load the corresponding resources, MFC will firs

The root cause of this problem is that applications that share MFC DLL (or MFC extension DLLs) with the MFC rule DLLs always use EXE resources by default, and we have to switch the handle of the resource module, which is implemented in three ways: Method one is used in DLL interface functions:Afx_manage_state (AfxGetStaticModuleState ()); Let's change the interface function Showdlg in the

Large applications are composed of many modules that complete relatively independent functions and collaborate with each other to complete the work of the entire software system. Some modules may have common functions and will still be used when constructing other software systems. When constructing a software system, if the source code of all modules is statically compiled into the entire application EXE file, some problems will occur: one drawback is that the size of the application is increas

MFC DLL Generally, there is a lot of knowledge about DLL in the introduction to Windows programming, while the introduction to MFC is rarely mentioned. Even if you use MFC to write a dynamic link library, it is necessary for programmers who are initially familiar with DLL to understand the background of DLL. In additio

This article illustrates the steps and implementation methods of C + + writing DLL dynamic link library. Share to everyone for your reference, specific as follows: When writing C + + programs, you often need to write a class as a DLL for the client to invoke. Such a DLL can export an entire class, or it can export a method of this class. First, export the entir

The previous section introduced the debugging and viewing of static link libraries (dynamic link library (DLL) programming in simple terms (I). This section mainly introduces non-MFC DLL. 4. Non-MFC DLL 4.1 A simple DLLSection 2nd describes how to provide the Add function interface using the static Link Library. Next we will look at how to use the dynamic link li
