For the first time, I was able to perform Oracle distributed transaction processing, and I was beaten by a storm. After two and a half days in a row, I finally completed the transaction. During this period, I encountered various problems, and I was tired of Google, at first, I was still confident that the last new error message was a bit desperate. Then I put my energy into an article so that future generations could not take a detour. During this period, I would like to thank Sam and King, who
When writing a class library project, there are often some special business needs to use the server side of the physical path, using the traditional System.IO.Directory.GetCurrentDirectory () method returned is the Winnt\System32 directory, which is generally not full Normal business requirements, and the physical directory where the DLL is to be run through assembly.getexecutingassembly (). CODEBASE attribute to be obtained, the specific reference me
In debug mode, the system prompts that msvcr90d. dll is not found,ProgramUnable to run
Method o: Re-generate a project. Sometimes you can repeat the project several times, but it does not guarantee that the problem will be solved.
Method 1: Use the release mode in solution configuration. If an error occurs again, it indicates that your program is wrong. In the realize mode, debugging is not convenient.
Therefore, we recommend that you use the follo
There are two types of libraries in C + +:1, Lib contains the function of the DLL file and the location of the function in the file (portal), the code by the runtime loaded in the process space by the DLL provided, called Dynamic Link library, the Dynamics link libraries.(This method is more flexible and the program is small, but requires both. exe and DLL to be
Small knowledge: the role and benefits of DLL files
As we all know, the software main program is generally exe type executable file, directly double-click it can start a software. But for DLL files, you probably don't know as much as EXE. A DLL is a "Dynamic link library" file that is an important part of a set of programs. In the development of many programs, b
Many times, we need to compile the. cs file individually into a. dll file, which requires the CSC command to compile the. cs file into a. dll dynamic link library file. The specific steps are as follows:
Open the Command Window-> enter CMD to the console->CD c:windowsmicrosoft.netframeworkv1.1.4322
Go to the directory where the vs.net is installed-> execute the CSC command csc/target:library file.cs-> A.
Exporting from a DLL using a DEF file
A module definition (. def) file is a text file that contains one or more module statements that describe various attributes of a DLL. If you do not use the __declspec (dllexport) keyword to export a DLL's functions, the DLL requires a. def file.
The. def file must contain at least the following module definition statements:
interprocess communication using dynamic link libraries.Implementation methodA dynamic-link library DLL is a file that contains a series of functions and data that the application can call its functions.In general, when an application calls a function inside a DLL, the operating system maps the file image of the DLL to the address space of the process, at which
First, DLL Overview:
The dynamic-link library (Dynamic-link Library), referred to as a DLL, is a very important component of Windows programming. There are many advantages to using DLLs:
(1) A dynamic connection using a DLL is not a copy of the library code, only the entry points and interfaces for functions are recorded in the program, the library code is load
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
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
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

Introduction
I believe that some friends with computer knowledge should have heard of "dll ". Especially those who have used the Windows operating system should have had the "miserable" experience of reinstalling the system many times-no matter how careful, no driver damage, no virus intrusion, after using (installing) The software for a period of time, I fo
. NET is a language that is built on virtual machines that directly generates the intermediate language of MSIL, and then the. NET compiler JIT interprets the image as native code and delivers CPU execution. Intermediate languages are easy to decompile, so study how to protect DLL files effectively.
My general approach is: strong signature + obfuscation + encryption.Strong signatureStrong-Named assemblies ensure that your assembly is unique and not t
After uninstalling the software, more or less will be on the machine residue of some useless files, such as DLL file, very annoying. Even more troubling, there are often cases where you cannot delete these remaining DLL files. The reason is that the DLL file is being invoked by a process that is running on the current system. After knowing the reason, we can easi
