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
Backdoor! I believe this term will not be unfamiliar to you, but it will not be harmful to you. However, as people's security awareness gradually increases, the "strong support" of anti-virus software is added ", so that traditional webshells cannot hide themselves. Anyone with a little knowledge about computers knows how to "Check ports" and "view processes" to discover some "clues ". In this way, the process and port are hidden. This article takes "DLL
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
. 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

The same problem is when I interview the director, the director asked me a question, these days have been busy, have not read a book, summed up this question today? Why does a process use a dynamic link library and another process can continue using it? At that time, the answer is very general, only half of the answer, and now here to summarize it!As we have said before, there are several ways to communicate between processes, but the dynamic link library We are talking about is also one of the
in recent times, often encountered these problems, a while ago, did not remember, did not think of recent research and some do not remember, today write it down for forgetting. The DLLs we provide to other languages are usually called C or C.+ + is written and then encapsulated. My side is also used in C + +. First, there are a few points to note:1, if the functionality is simple, or if you do not use a third-party library (such as an MFC-brought library), create a Win32 console program, and the
