IMHO, a DLL which has C++ code inside, should be constructed with these problems in mind. All three these compilers, AFAIK, uses different approaches to aforementioned mechanism.

For application development under Windows there are (among others) three main compilers which are widespread: MS C++ compiler, GCC MinGW porting and BCC32 (BorCodeDero, aka BorCodeDero 32 bit C++ Compiler). So I suspect that some mechanisms behind the scenes, like virtual function handling or C++ language exception handling, can be implemented very differently between different compilers. C++ ABI is not standardized on Windows as is for C. Ok, it's a possible solution, but it's dependent by the compiler used, i.e., IMHO only the same C++ compiler used to build the DLL can be used to consume it. NET C#, you can only 'DllImport' or 'PInvoke' globally exported functions from a C++ DLL. For a C++ DLL to be imported in a C application, global functions.C++ DLL built from different compilers may not be consumed by a C++ Application/other C++ DLL directly because C++ compilers have different 'name mangling' specifications. *This is why we need to compile the source of a C++ DLL project along with our C++ application to ensure they are built using the same compiler.When we add the path to the header files in our application project, we are just telling the compiler to locate the header files we are using from that location.īut when we add reference to our DLL project from our application project, we are basically telling the Linker to link the header files of the actual implementation of our Win32 DLL. Navigate to ' Release' folder and launch MyWin32CppApp.exe. Click 'Add New References' and select the DLL project we previously created. Second, right click Application project and select 'References.'. This will tell the compiler to locate MyWin32ClassOne.h and MyWin32ClassTwo.h in this location.

#include ' MyWin32ClassOne.h' #include ' MyWin32ClassTwo.h' using namespace MyWin32CppDLL Ĭout General > Additional Include Directories' then assign the full path where the header files of the DLL are located. Place the below code to their respective files. I just wanted to add two classes into our DLL to illustrate that we can add classes as many as we like into a DLL. Then let's add four files into our project ( MyWin32ClassOne.h, MyWin32ClassOne.cpp, MyWin32ClassTwo.h, and MyWin32ClassTwo.cpp). A Win32 Application Wizard window will popup - click Next button and then select the Application type: 'DLL' and tick Additional options: 'Empty project' and finally click the Finish button. Let's open Visual Studio 2010 and select 'File > New Project > Visual C++ > Win32 > Win32 Project' and name the new project 'MyWin32CppDLL' and then Press OK. Other version may be used but with some slight differences.) (It is recommended to use VS 2010 since this was the actual IDE used to build this project. More of that, it would be easier to understand if we will just see the working code, right? So let's dive into the code project! Using the codeįirst, let's create a C++ Win32 DLL using Visual Studio 2010. In this manner, you only code the math operations once, while your two applications or even your future applications can use the same Math.dll for arithmetic operations. For example you have two applications that use arithmetic operations like Addition, Subtraction, Multiplication, and Division, instead of coding the same operations in each application, you can just put these operations inside a DLL (e.g., Math.dll) and reference the DLL from the two applications. DLL is a great way to distribute and reuse code. You can simply think of a DLL or Dynamic Link Library as a collection of codes, data, or resources that is packed together into one file. NET Framework languages like C#, VB.NET, or with VC++. CLR DLLs are called managed code while C++ Win32 DLLs are called unmanaged code. CLR DLL does not produce binary code but it generates an Intermediate Language code or IL code which is not covered in this article. Note that there is also another kind of DLL which is a CLR DLL.

There are many uses of DLL but this article only focuses on how to create and use a C++ Win32 DLL as well as giving you a skeleton on the structure of a C++ Win32 DLL. In this article, we will create a small and simple Win32 C++ DLL project using an Empty Project template from Visual Studio 2010 and then create a separate Win32 Console Application to consume the DLL functionalities.
