kernel32 dll

Here we will talk about how to call functions in DLL. Let's take a simple example:[Code] varmypage: twizardpage; button: tnewbutton; CNT: integer; function getcurrentprocessid (): integer; External 'getcurrentprocessid @ c: \ windows \ system32 \ kernel32.dll '; procedure buttononclick (Sender: tobject); begin msgbox (inttostr (getcurrentprocessid (), mbinformati

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

Recently, I am working on something that needs to intercept process initiation and inject DLL under ring0 (DLL is used to hook the API under ring3). There are many implementation methods. Here we use the idea provided by sudami, the reference code provided by another hero. Although this item has no technical knowledge, it is still a long time for people like me who are just getting started with the kernel t

Zen CentThe article has been collected, written too well, back up a copy of theAuthor: http://www.cnblogs.com/shangdawei/p/4058452.htmlIntroductionbelieve that some computer knowledge of friends should have heard of the "DLL." 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 "

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

Dynamic | function In C + + We can invoke DLL's exported function dynamically through LoadLibrary, GetProcAddress.Can this be done in C # as well?In Dotnet 2.0, this is OK, thanks to the 2.0 new function.Marshal.getdelegateforfunctionpointer methodThis method is new in the. NET Framework version 2.0. Converts an unmanaged function pointer to a delegate.The instance code is as follows: public delegate int MsgBox (int hwnd,string msg,string cpp,int OK); [DllImport ("

What is the relationship between lib and dll?From http://blog.sina.com.cn/s/blog_4b9b714a0100gzip.html (1) lib is required during compilation and dll is required during runtime.If you need to complete source code compilation, it is enough to have lib.If dynamic connection is also enabled, dll is enough.In the development and debugging stages, it is best to have b

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

Chapter 1 Why dynamic link library (DLL) When you mention a DLL, you will not be unfamiliar. in Windows, there are a large number of files suffixed with DLL, which are an important guarantee to ensure the normal operation and maintenance of Windows. (For example, the Win95 System directory contains more than 500 DLL fi

There are many methods for calling the function exported from Win32 DLL in C #. This article will summarize. There are two possible cases: DLL file name and function name are known during compilation The DLL file name (function name) can be obtained only during runtime) DLL file name known during compilation In th

4.1 A simple DLL Section 2nd describes how to provide the Add function interface using the static Link Library. Next we will look at how to use the dynamic link library to implement the Add function with the same function. For example --> Figure 6.

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
