Visual c ++ DLL programming implementation
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

Today, when running the "pleasant goat and gray wolf Screensaver. exe" program under the Win8.1 system, it suddenly pops up as shown in the System error window:

We know that the Windows DLL is not able to run independently, but Microsoft has provided rundll32.exe for running DLLs.
Test first: Run "Rundll32.exe shell32.dll,restartdialog" and the restart dialog will pop up. The same way you can turn on other features of Windows systems.
Here's a look at how to define your own DLL to let Rundll32.exe run.

In particular, those who have used Windows operating systems should have had a "tragic" experience of reloading the system many times-no matter how careful, no driver damage, no virus intrusion, still using (installed) a period
Preface
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 "
Brief introductionIn the previous chapters, I introduced knowledge about remote thread injection, and implemented backdoor. dll files into the Explorer.exe to bypass the firewall bounce back door. But an. exe file always takes a. dll file when it is injected it is really troublesome, then there is no way to do not apply to the. dll file implementation injection?T
. NET is a language that is built on a virtual machine that generates the intermediate language of the MSIL directly, and then the. NET compiler JIT interprets the image as native code and delivers CPU execution. The intermediate language is easy to decompile, so study how to effectively protect DLL files. My approximate method is: Strong signature + obfuscation + encryption. Strong-Signed strong-named assemblies ensure that your assemblies are unique

Msvcr100.dll is a dynamic link library of Visual Studio 2010, if a program is developed with it, then the program may need to run the dynamic link library, some programs directly packaged it into the installation directory, and register, there will be no missing problems; However, some programs have the default system in the dynamic link library, no processing, there will be missing problems. So what is the reason for the loss of Msvcr100.
The use of functions in the C + + DLL and callbacks in Unity3d is described earlier in this article, but the final goal is to let the functions in the Lua script be called in Unity3d, which is now implemented.First, focus on the previous two articles:1.Unity3d call C + + DLL (Win platform)2,Unity3d call C + + DLL DLL c

This article is a VB-generated DLL that encapsulates ASP code to connect to a database (for example, in an Access database).
In general, when we use ASP to connect to an Access database, we typically do the following:

Set Proconn=server.createobject ("ADODB. CONNECTION ")
Proconn.open "Driver={microsoft Access driver (*.mdb)};uid=;p wd=123;dbq=" Server.MapPath ("db.asp")
