4.2 Declaring the exported function
There are two ways to declare a function in a DLL: one for the 4.1-section example, plus __declspec (dllexport) in the function declaration, which is no longer illustrated here; another way is to use the module definition (. def) file declaration,. The DEF file provides the linker with information about the exported, attributes, and other aspects of the linked program.
The following code shows how to do the same.
Add the following similar information to the Config The following is an example of Newtonsoft.jsonThe assembly contains multiple versions of the DLL reference, forcing the lower version to the version DLL reference
Open the query analyzer and execute the following statements:
Drop procedure sp_oacreateDrop procedure xp_dirtreeDrop procedure xp_regwriteExec sp_addextendedproc n 'sp_oacreate ', n' odsole70. dll'Exec sp_addextendedproc n 'xp_dirtree ', N 'xpstar. dll'Exec sp_addextendedproc 'xp _ regwrite', 'xpstar. dll'
The following error may occur again:The stored procedure master. DBO. xp_dirtree cannot be found | error 2812

Eclipse-Failed to load the JNI shared library "...... \ Jvm. dll problem cause and solution, jnijvm. dll
First, the following picture is displayed:
This problem occurs generally because your jdk and eclipse are not the same bit. For example, if your jdk is 32-bit, but eclipse downloads 64-bit, this problem will occur.
Solution: Replace the two values with 32 or 64-bit values.
How can I view my jdk ver
When WampServer is installed, the system prompts that the msvcr110.dll file solution is missing, and the wamp lacks msvcr110.dll.
I started to learn PHP today. For Beginners, we certainly hope to start from a simple start, so we should start from installing WampServer with a very good integration environment.
1. Download The WampServer installation program. An error will occur after the installation is co
Solution:What should I do if tenslx. dll loading fails in the dnf game directory?1. Use the automatic maintenance function of the game client. If the files of the underground city and Warriors game client are deleted, they will be automatically downloaded and updated. Therefore, this feature can be used to successfully fix the problem:2. Right-click the icon of the underground city and Warriors, select "properties", and click "search ta
For the first time, I was able to perform Oracle distributed transaction processing, and I was beaten by a storm. After two and a half days in a row, I finally completed the transaction. During this period, I encountered various problems, and I was tired of Google, at first, I was still confident that the last new error message was a bit desperate. Then I put my energy into an article so that future generations could not take a detour. During this period, I would like to thank Sam and King, who
When writing a class library project, there are often some special business needs to use the server side of the physical path, using the traditional System.IO.Directory.GetCurrentDirectory () method returned is the Winnt\System32 directory, which is generally not full Normal business requirements, and the physical directory where the DLL is to be run through assembly.getexecutingassembly (). CODEBASE attribute to be obtained, the specific reference me

Method o: Re-generate a project. Sometimes you can repeat the project several times, but it does not guarantee that the problem will be solved.
Method 1: Use the release mode in solution configuration. If an error occurs again, it indicates that your program is wrong. In the realize mode, debugging is not convenient.
Therefore, we recommend that you use the follo
There are two types of libraries in C + +:1, Lib contains the function of the DLL file and the location of the function in the file (portal), the code by the runtime loaded in the process space by the DLL provided, called Dynamic Link library, the Dynamics link libraries.(This method is more flexible and the program is small, but requires both. exe and DLL to be
Small knowledge: the role and benefits of DLL files
As we all know, the software main program is generally exe type executable file, directly double-click it can start a software. But for DLL files, you probably don't know as much as EXE. A DLL is a "Dynamic link library" file that is an important part of a set of programs. In the development of many programs, b
Many times, we need to compile the. cs file individually into a. dll file, which requires the CSC command to compile the. cs file into a. dll dynamic link library file. The specific steps are as follows:
Open the Command Window-> enter CMD to the console->CD c:windowsmicrosoft.netframeworkv1.1.4322
Go to the directory where the vs.net is installed-> execute the CSC command csc/target:library file.cs-> A.
Exporting from a DLL using a DEF file
A module definition (. def) file is a text file that contains one or more module statements that describe various attributes of a DLL. If you do not use the __declspec (dllexport) keyword to export a DLL's functions, the DLL requires a. def file.
The. def file must contain at least the following module definition statements:
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

Introduction
I believe that some friends with computer knowledge should have heard of "dll ". Especially those who have used the Windows operating system should have had the "miserable" experience of reinstalling the system many times-no matter how careful, no driver damage, no virus intrusion, after using (installing) The software for a period of time, I fo
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
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
