Recently, someone asked in the Group how to use C language to compile DLL files (dynamic link library ).I didn't care too much about this problem or try any solution. After all, I used VB (now I use it.. Net). Creating a DLL is just a click to create an ActiveX dll project. Today, I chatted with my friends online and read several files that he showed me. I sudden
1. Load the lib/header fileThere are two ways of doing this:(1) for the current project1 Step One: Item--Properties->c/c++-> General , additional Include directories (browse. h file path) Add include file 2 Second step: Project--Properties->c/c++ Add-on dependency (write Lib name), linker--, input to the library file 3 project, Properties--- Additional Dependencies 4 Step three: Add #include (This step can also show the call #pragma comment (lib, "***.lib") in the code.)(if not added, connect
1. What is the missing DLL file?
As a file associated with an EXE, the DLL file can be in the same directory as its associated EXE master file, or it may not be in the same directory. Many program shares use DLL files that exist with the system in the Windows directory or its subdirectories, the files that are included with the system, and the software installs
, you can consider using static global thread local variables, that is:_ Declspec (thread) int tls_ I = 1;This variable makes the compiler ensure that tls_ I corresponds to each thread, that is, each thread has a copy of tls_ I, Which is thread security.2. Multiple Functions are exported from the dynamic library, and data transmission exists between multiple functions.As mentioned above, DLL exports multiple functions, one initialization, one resource

Third-party libraries are often used. For example, glut, FreeType, SDL, and cegui and OSG.
Although these libraries are open-source, they are often used and are not modified.
Three things are involved: the. H. Lib. dll file.
There are three main modes:
. H +. Lib
. H +. Lib +. dll
. Dll

played a role. This reuse is referred to as "black box multiplexing".There are two types of executables in the Windows operating system, with the following suffix. exe and. dll. The difference is that the. exe file can be run independently of the memory, and the. dll file cannot, it can only be called by other processes. However, in any format, they are binary files. The above-mentioned "binary level" code
"@" and then the function name, the symbol "@" and the number of bytes of the parameter are followed. For example, the modifier of the int func (int A, double B) function is @ func @ 12. For the "C ++" function, it is different.In the future, compilers may use different registers to store parameters.
Functions declared in DLL using _ declspec (dllexport:_ Declspec (dllexport) only indicates that this function is a

Before the opening, I want to despise myself. I don't need to write this thing at all. I already have something to implement. As my team lead said, there are too few open-source projects. In fact, this thing can be completely solved by ILMerge.
Then let's talk about the preface. After developing things for a long time, we will always accumul
Before writing, I would like to briefly introduce the differences between hosting and non-hosting C ++. In fact, I have not thoroughly understood the features of hosting C ++, the biggest feature is that the system can debug and recycle relevant code resources. Like C #, the programming style is similar to C ++. Therefore, this determines that C # can be perfectly integrated with hosted C ++. It should be said that the dll generated by hosting C ++ is
. Net is a language based on virtual machines. It directly generates the msil intermediate language, and then the. NET compiler JIT interprets the image as the local code and delivers the CPU for execution. The intermediate language is easily decompiled, so we will study how to effectively protect DLL files.
My general method is:Strong signature + obfuscation + encryption.
Strong SignatureA strongly-named Assembly ensures that your assembly is unique
In plug-in development of Microsoft Dynamics CRM 4.0, third-party DLL is often referenced. If it is deployed on a disk, it will not have a great impact. If it is deployed on a database, the plug-in cannot run because it references a third-party DLL. In my opinion, the plug-in deployment tool only serializes the plug-in DLL to the database, but the third-party

In this book, the author introduces three methods to inject code into other processes, one of which is the global message hook. I first learned about global hooks from this book.We should all know that the global message hook depends on a DLL
Introduction
The DLL trap is a strange problem.
I believe that many users have such experiences. If your experiences were originally designed to run today, after you installed a new experience, all of a sudden, the power supply cannot work. This is not a problem with your hardware or application process.But the lack of design for business systems, this is usually because the new application version overwrites the shared program library (
After one night of hard work, I decided to write down some of my experiences to avoid repeated work in the future.
C # compared with C/C ++, the advantage of the former lies in the UI, and the advantage of the latter lies in the algorithm. Although the pointer in C ++ is disgusting, it is quite convenient to use it properly, the most important issue is that many popular development tool libraries on the market almost do not support C ++, but it is rare to fully support C #. As the CPU has grown
DLL file is a dynamic database file, is an executable file, in general, he is to allow the program to perform special tasks required by the Code and resources, the general DLL file is followed by the DLL extension file, but some may also be exe and other extensions. They provide code, data, or functions to programs running under the Windows operating system. Prog
