Preface Since Microsoft launched a 16-bit Windows operating system, every version of Windows operating system is dependent on functions and data in the dynamic link library (DLL, in fact, almost all content in Windows is represented by DLL in one or another form, for example, the displayed fonts and icons are stored in the gdi
1. dll Concept
DLL (Dynamic linkable Library), which can provide some functions, variables, or classes to the program. These can be used directly.
Differences between static and dynamic libraries:
(1) Both static and dynamic libraries share code. The static Link Library includes all the final commands in the final generated EXE file. The dynamic link library does not need to be included in the final EXE fil
Before the write operation, or to briefly talk about the difference between managed and unmanaged C + + Well, I actually did not have a deep understanding of the characteristics of managed C + +, its biggest feature is that the system can debug the collection of related code resources, like C # features, just the programming style and C + + Similar , so this determines that C # and managed C + + can be perfectly combined. managed C + + generated DLLs and C # generated DLLs should be said to be n
What about the loss of DLL files? believe that many friends encounter running a program or game will appear prompts, said the system is missing what DLL file, this time we need to find this file and install, the following small set for everyone to bring the use of DLL Repair tool Introduction, to understand the next bar.

Static calls in C # C++dll and C # in dynamic call C++dllIn recent projects, involving the project source code security issues, because the code is written in C #, easy to be anti-compilation, so decided to extract the core algorithm is written in C + +, C + + so far seems not to be very good anti-compilation, of course, if you are an anti-assembly master, it may be possible to decompile. In this way, it involves invoking C # managed code with C + + u
The principle of this method is to write a DLL with the same interface function as the DLL called by the original process, and then replace the original DLL with our DLL. During the replacement process, we will write functions of interest to replace the original functions, while functions of the original

First, let's clarify the concept of the Library. The library stores binary encoding. Looking at the development path of programming technology, we can see a clear development context: code> static library> dyn

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:

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 (

Before starting this article, I will make a small investigation: How many friends like reboot? Answer A: I like it. I need to reboot n times every day. Answer B: I don't like it. Do not reboot for a week. If there is no accident, I believe most people will be in B's category. After all, few people will be willing to interrupt what they do and save the articles and codes being edited, then restart and wait for a few minutes before re-opening the document and code editing.

It's not difficult to include your own DLLs in the kernel, but that doesn't mean your DLL can be loaded into slot 1. May be careful as you have found, when you use an application to load a DLL that you manually include in the kernel, the DLL must be loaded into the address space of the calling process, rather than the unique address space of the system
