The DLL (Dynamic Link Library) plays an important role in windows applications system. Mar 14, 2019 C - Windows - Creating a dynamic-link library (DLL) Submitted by Mi-K on Thursday, March 14, 2019 - 11:08pm Creating a.DLL is an interesting process that allows a better comprehension how a dynamic-link library works on Windows.

Implicit linking, where the operating system loads the DLL at the same time as the executable that uses it. The client executable calls the exported functions of the DLL the same way as if the functions were statically linked and contained within the executable. Implicit linking is sometimes referred to as static load or load-time dynamic linking.
Explicit linking, where the operating system loads the DLL on demand at runtime. An executable that uses a DLL by explicit linking must explicitly load and unload the DLL. It must also set up a function pointer to access each function it uses from the DLL. Unlike calls to functions in a statically linked library or an implicitly linked DLL, the client executable must call the exported functions in an explicitly linked DLL through function pointers. Explicit linking is sometimes referred to as dynamic load or run-time dynamic linking.

An executable can use either linking method to link to the same DLL. Furthermore, these methods aren't mutually exclusive; one executable may implicitly link to a DLL, and another might attach to it explicitly.

Determine which linking method to use

Whether to use implicit linking or explicit linking is an architectural decision you must make for your application. There are advantages and disadvantages to each method.

Implicit Linking

Implicit linking occurs when an application's code calls an exported DLL function. When the source code for the calling executable is compiled or assembled, the DLL function call generates an external function reference in the object code. To resolve this external reference, the application must link with the import library (.lib file) provided by the maker of the DLL.

The import library only contains code to load the DLL and to implement calls to functions in the DLL. Finding an external function in an import library informs the linker that the code for that function is in a DLL. To resolve external references to DLLs, the linker simply adds information to the executable file that tells the system where to find the DLL code when the process starts up.

When the system starts a program that contains dynamically linked references, it uses the information in the program's executable file to locate the required DLLs. If it can't locate the DLL, the system terminates the process, and displays a dialog box that reports the error. Otherwise, the system maps the DLL modules into the process address space.

If any of the DLLs has an entry-point function for initialization and termination code such as DllMain, the operating system calls the function. One of the parameters passed to the entry-point function specifies a code that indicates the DLL is attaching to the process. If the entry-point function doesn't return TRUE, the system terminates the process and reports the error.

Finally, the system modifies the executable code of the process to provide starting addresses for the DLL functions.

Like the rest of a program's code, the loader maps DLL code into the address space of the process when the process starts up. The operating system loads it into memory only when needed. As a result, the PRELOAD and LOADONCALL code attributes used by .def files to control loading in previous versions of Windows no longer have meaning.

Explicit Linking

Most applications use implicit linking because it's the easiest linking method to use. However, there are times when explicit linking is necessary. Here are some common reasons to use explicit linking:

The application doesn't know the name of a DLL that it loads until run time. For example, the application might obtain the name of the DLL and the exported functions from a configuration file at startup.
A process that uses implicit linking is terminated by the operating system if the DLL isn't found at process startup. A process that uses explicit linking isn't terminated in this situation, and can attempt to recover from the error. For example, the process could notify the user of the error and have the user specify another path to the DLL.
A process that uses implicit linking is also terminated if any of the DLLs it's linked to have a DllMain function that fails. A process that uses explicit linking isn't terminated in this situation.
An application that implicitly links to many DLLs can be slow to start because Windows loads all the DLLs when the application loads. To improve startup performance, an application might only use implicit linking for DLLs required immediately after loading. It might use explicit linking to load other DLLs only when they're needed.
Explicit linking eliminates the need to link the application by using an import library. If changes in the DLL cause the export ordinals to change, applications don't have to relink if they call GetProcAddress using the name of a function and not an ordinal value. Applications that use implicit linking must still relink to the changed import library.

Here are two hazards of explicit linking to be aware of:

If the DLL has a DllMain entry point function, the operating system calls the function in the context of the thread that called LoadLibrary. The entry-point function isn't called if the DLL is already attached to the process because of a previous call to LoadLibrary that has had no corresponding call to the FreeLibrary function. Explicit linking can cause problems if the DLL uses a DllMain function to initialize each thread of a process, because any threads that already exist when LoadLibrary (or AfxLoadLibrary) is called aren't initialized.
If a DLL declares static-extent data as __declspec(thread), it can cause a protection fault if explicitly linked. After the DLL is loaded by a call to LoadLibrary, it causes a protection fault whenever the code references this data. (Static-extent data includes both global and local static items.) That's why, when you create a DLL, you should avoid using thread-local storage. If you can't, then inform your DLL users about the potential pitfalls of dynamically loading your DLL. For more information, see Using thread local storage in a dynamic-link library (Windows SDK).

How to use implicit linking

To use a DLL by implicit linking, client executables must obtain these files from the provider of the DLL:

One or more header files (.h files) that contain the declarations of the exported data, functions, and C++ classes in the DLL. The classes, functions, and data exported by the DLL must all be marked __declspec(dllimport) in the header file. For more information, see dllexport, dllimport.
An import library to link into your executable. The linker creates the import library when the DLL is built. For more information, see LIB files as linker input.
The actual DLL file.

To use the data, functions, and classes in a DLL by implicit linking, any client source file must include the header files that declare them. From a coding perspective, calls to the exported functions are just like any other function call.

To build the client executable file, you must link with the DLL's import library. If you use an external makefile or build system, specify the import library together with the other object files or libraries that you link.

Welcome to the Wav Voice Tune system. Auto tune in chinese.

The operating system must be able to locate the DLL file when it loads the calling executable. That means you must either deploy or verify the existence of the DLL when you install your application.

How to link explicitly to a DLL

To use a DLL by explicit linking, applications must make a function call to explicitly load the DLL at run time. To explicitly link to a DLL, an application must:

Call LoadLibraryEx or a similar function to load the DLL and obtain a module handle.
Call GetProcAddress to obtain a function pointer to each exported function that the application calls. Because applications call the DLL functions through a pointer, the compiler doesn't generate external references, so there's no need to link with an import library. However, you must have a typedef or using statement that defines the call signature of the exported functions that you call.
Call FreeLibrary when done with the DLL.

For example, this sample function calls LoadLibrary to load a DLL named 'MyDLL', calls GetProcAddress to obtain a pointer to a function named 'DLLFunc1', calls the function and saves the result, and then calls FreeLibrary to unload the DLL.

Unlike this example, in most cases you should call LoadLibrary and FreeLibrary only once in your application for a given DLL. It's especially true if you're going to call multiple functions in the DLL, or call DLL functions repeatedly.

Create the DLL project

In this set of tasks, you create a project for your DLL, add code, and build it. To begin, start the Visual Studio IDE, and sign in if you need to. The instructions vary slightly depending on which version of Visual Studio you're using. Make sure you have the correct version selected in the control in the upper left of this page.

To create a DLL project in Visual Studio 2019

On the menu bar, choose File > New > Project to open the Create a New Project dialog box.
At the top of the dialog, set Language to C++, set Platform to Windows, and set Project type to Library.
From the filtered list of project types, select Dynamic-link Library (DLL), and then choose Next.
In the Configure your new project page, enter MathLibrary in the Project name box to specify a name for the project. Leave the default Location and Solution name values. Set Solution to Create new solution. Uncheck Place solution and project in the same directory if it's checked.
Choose the Create button to create the project.

When the solution is created, you can see the generated project and source files in the Solution Explorer window in Visual Studio.

To create a DLL project in Visual Studio 2017

On the menu bar, choose File > New > Project to open the New Project dialog box.
In the left pane of the New Project dialog box, select Installed > Visual C++ > Windows Desktop. In the center pane, select Dynamic-Link Library (DLL). Enter MathLibrary in the Name box to specify a name for the project. Leave the default Location and Solution name values. Set Solution to Create new solution. Check Create directory for solution if it's unchecked.
Choose the OK button to create the project.

When the solution is created, you can see the generated project and source files in the Solution Explorer window in Visual Studio.

To create a DLL project in Visual Studio 2015 and older versions

On the menu bar, choose File > New > Project.
In the left pane of the New Project dialog box, expand Installed > Templates, and select Visual C++, and then in the center pane, select Win32 Console Application. Enter MathLibrary in the Name edit box to specify a name for the project. Leave the default Location and Solution name values. Set Solution to Create new solution. Check Create directory for solution if it's unchecked.
Choose the OK button to dismiss the New Project dialog and start the Win32 Application Wizard.
Choose the Next button. On the Application Settings page, under Application type, select DLL.
Choose the Finish button to create the project.

When the wizard completes the solution, you can see the generated project and source files in the Solution Explorer window in Visual Studio.

Right now, this DLL doesn't do very much. Next, you'll create a header file to declare the functions your DLL exports, and then add the function definitions to the DLL to make it more useful.

To add a header file to the DLL

To create a header file for your functions, on the menu bar, choose Project > Add New Item.
In the Add New Item dialog box, in the left pane, select Visual C++. In the center pane, select Header File (.h). Specify MathLibrary.h as the name for the header file.
Choose the Add button to generate a blank header file, which is displayed in a new editor window.
Replace the contents of the header file with this code:

This header file declares some functions to produce a generalized Fibonacci sequence, given two initial values. A call to fibonacci_init(1, 1) generates the familiar Fibonacci number sequence.

Notice the preprocessor statements at the top of the file. The new project template for a DLL project adds PROJECTNAME_EXPORTS to the defined preprocessor macros. In this example, Visual Studio defines MATHLIBRARY_EXPORTS when your MathLibrary DLL project is built.

When the MATHLIBRARY_EXPORTS macro is defined, the MATHLIBRARY_API macro sets the __declspec(dllexport) modifier on the function declarations. This modifier tells the compiler and linker to export a function or variable from the DLL for use by other applications. When MATHLIBRARY_EXPORTS is undefined, for example, when the header file is included by a client application, MATHLIBRARY_API applies the __declspec(dllimport) modifier to the declarations. This modifier optimizes the import of the function or variable in an application. For more information, see dllexport, dllimport.

To add an implementation to the DLL

In Solution Explorer, right-click on the Source Files node and choose Add > New Item. Create a new .cpp file called MathLibrary.cpp, in the same way that you added a new header file in the previous step.
In the editor window, select the tab for MathLibrary.cpp if it's already open. If not, in Solution Explorer, double-click MathLibrary.cpp in the Source Files folder of the MathLibrary project to open it.
In the editor, replace the contents of the MathLibrary.cpp file with the following code:

In the editor window, select the tab for MathLibrary.cpp if it's already open. If not, in Solution Explorer, double-click MathLibrary.cpp in the Source Files folder of the MathLibrary project to open it.
In the editor, replace the contents of the MathLibrary.cpp file with the following code:

To verify that everything works so far, compile the dynamic link library. To compile, choose Build > Build Solution on the menu bar. The DLL and related compiler output are placed in a folder called Debug directly below the solution folder. If you create a Release build, the output is placed in a folder called Release. The output should look something like this:

Congratulations, you've created a DLL using Visual Studio! Next, you'll create a client app that uses the functions exported by the DLL.

Create a client app that uses the DLL

When you create a DLL, think about how client apps may use it. To call the functions or access the data exported by a DLL, client source code must have the declarations available at compile time. At link time, the linker requires information to resolve the function calls or data accesses. A DLL supplies this information in an import library, a file that contains information about how to find the functions and data, instead of the actual code. And at run time, the DLL must be available to the client, in a location that the operating system can find.

Whether it's your own or from a third-party, your client app project needs several pieces of information to use a DLL. It needs to find the headers that declare the DLL exports, the import libraries for the linker, and the DLL itself. One solution is to copy all of these files into your client project. For third-party DLLs that are unlikely to change while your client is in development, this method may be the best way to use them. However, when you also build the DLL, it's better to avoid duplication. If you make a local copy of DLL files that are under development, you may accidentally change a header file in one copy but not the other, or use an out-of-date library.

To avoid out-of-sync code, we recommend you set the include path in your client project to include the DLL header files directly from your DLL project. Also, set the library path in your client project to include the DLL import libraries from the DLL project. And finally, copy the built DLL from the DLL project into your client build output directory. This step allows your client app to use the same DLL code you build.

To create a client app in Visual Studio

On the menu bar, choose File > New > Project to open the Create a new project dialog box.
At the top of the dialog, set Language to C++, set Platform to Windows, and set Project type to Console.
From the filtered list of project types, choose Console App then choose Next.
In the Configure your new project page, enter MathClient in the Project name box to specify a name for the project. Leave the default Location and Solution name values. Set Solution to Create new solution. Uncheck Place solution and project in the same directory if it's checked.
Choose the Create button to create the client project.

A minimal console application project is created for you. The name for the main source file is the same as the project name that you entered earlier. In this example, it's named MathClient.cpp. You can build it, but it doesn't use your DLL yet.

To create a client app in Visual Studio 2017

To create a C++ app that uses the DLL that you created, on the menu bar, choose File > New > Project.
In the left pane of the New Project dialog, select Windows Desktop under Installed > Visual C++. In the center pane, select Windows Console Application. Specify the name for the project, MathClient, in the Name edit box. Leave the default Location and Solution name values. Set Solution to Create new solution. Check Create directory for solution if it's unchecked.
Choose OK to create the client app project.

To create a client app in Visual Studio 2015

To create a C++ app that uses the DLL that you created, on the menu bar, choose File > New > Project.
In the left pane of the New Project dialog, select Win32 under Installed > Templates > Visual C++. In the center pane, select Win32 Console Application. Specify the name for the project, MathClient, in the Name edit box. Leave the default Location and Solution name values. Set Solution to Create new solution. Check Create directory for solution if it's unchecked.
Choose the OK button to dismiss the New Project dialog and start the Win32 Application Wizard. On the Overview page of the Win32 Application Wizard dialog box, choose the Next button.
On the Application Settings page, under Application type, select Console application if it isn't already selected.
Choose the Finish button to create the project.

When the wizard finishes, a minimal console application project is created for you. The name for the main source file is the same as the project name that you entered earlier. In this example, it's named MathClient.cpp. You can build it, but it doesn't use your DLL yet.

Next, to call the MathLibrary functions in your source code, your project must include the MathLibrary.h file. You could copy this header file into your client app project, then add it to the project as an existing item. This method can be a good choice for third-party libraries. However, if you're working on the code for your DLL and your client at the same time, the header files could get out of sync. To avoid this issue, set the Additional Include Directories path in your project to include the path to the original header.

To add the DLL header to your include path

Right-click on the MathClient node in Solution Explorer to open the Property Pages dialog.
In the Configuration drop-down box, select All Configurations if it's not already selected.
In the left pane, select Configuration Properties > C/C++ > General.
In the property pane, select the drop-down control next to the Additional Include Directories edit box, and then choose Edit.
Double-click in the top pane of the Additional Include Directories dialog box to enable an edit control. Or, choose the folder icon to create a new entry.
In the edit control, specify the path to the location of the MathLibrary.h header file. You can choose the ellipsis (..) control to browse to the correct folder.
You can also enter a relative path from your client source files to the folder that contains the DLL header files. If you followed the directions to put your client project in a separate solution from the DLL, the relative path should look like this:
..MathLibraryMathLibrary
If your DLL and client projects are in the same solution, the relative path might look like this:
.MathLibrary
When the DLL and client projects are in other folders, adjust the relative path to match. Or, use the ellipsis control to browse for the folder.
After you've entered the path to the header file in the Additional Include Directories dialog box, choose the OK button. In the Property Pages dialog box, choose the OK button to save your changes.

You can now include the MathLibrary.h file and use the functions it declares in your client application. Replace the contents of MathClient.cpp by using this code:

This code can be compiled, but not linked. If you build the client app now, the error list shows several LNK2019 errors. That's because your project is missing some information: You haven't specified that your project has a dependency on the MathLibrary.lib library yet. And, you haven't told the linker how to find the MathLibrary.lib file.

To fix this issue, you could copy the library file directly into your client app project. The linker would find and use it automatically. However, if both the library and the client app are under development, that might lead to changes in one copy that aren't shown in the other. To avoid this issue, you can set the Additional Dependencies property to tell the build system that your project depends on MathLibrary.lib. And, you can set an Additional Library Directories path in your project to include the path to the original library when you link.

To add the DLL import library to your project

Right-click on the MathClient node in Solution Explorer and choose Properties to open the Property Pages dialog.
In the Configuration drop-down box, select All Configurations if it's not already selected. It ensures that any property changes apply to both Debug and Release builds.
In the left pane, select Configuration Properties > Linker > Input. In the property pane, select the drop-down control next to the Additional Dependencies edit box, and then choose Edit.
In the Additional Dependencies dialog, add MathLibrary.lib to the list in the top edit control.
Choose OK to go back to the Property Pages dialog box.
In the left pane, select Configuration Properties > Linker > General. In the property pane, select the drop-down control next to the Additional Library Directories edit box, and then choose Edit.
Double-click in the top pane of the Additional Library Directories dialog box to enable an edit control. In the edit control, specify the path to the location of the MathLibrary.lib file. By default, it's in a folder called Debug directly under the DLL solution folder. If you create a release build, the file is placed in a folder called Release. You can use the $(IntDir) macro so that the linker can find your DLL, no matter which kind of build you create. If you followed the directions to put your client project in a separate solution from the DLL project, the relative path should look like this:
..MathLibrary$(IntDir)
If your DLL and client projects are in other locations, adjust the relative path to match.
Once you've entered the path to the library file in the Additional Library Directories dialog box, choose the OK button to go back to the Property Pages dialog box. Choose OK to save the property changes.

Your client app can now compile and link successfully, but it still doesn't have everything it needs to run. When the operating system loads your app, it looks for the MathLibrary DLL. If it can't find the DLL in certain system directories, the environment path, or the local app directory, the load fails. Depending on the operating system, you'll see an error message like this:

One way to avoid this issue is to copy the DLL to the directory that contains your client executable as part of the build process. You can add a Post-Build Event to your project, to add a command that copies the DLL to your build output directory. The command specified here copies the DLL only if it's missing or has changed. It uses macros to copy to and from the Debug or Release locations, based on your build configuration.

To copy the DLL in a post-build event

Right-click on the MathClient node in Solution Explorer and choose Properties to open the Property Pages dialog.
In the Configuration drop-down box, select All Configurations if it isn't already selected.
In the left pane, select Configuration Properties > Build Events > Post-Build Event.
In the property pane, select the edit control in the Command Line field. If you followed the directions to put your client project in a separate solution from the DLL project, then enter this command:
xcopy /y /d '..MathLibrary$(IntDir)MathLibrary.dll' '$(OutDir)'
If your DLL and client projects are in other directories, change the relative path to the DLL to match.
Choose the OK button to save your changes to the project properties.

Now your client app has everything it needs to build and run. Build the application by choosing Build > Build Solution on the menu bar. The Output window in Visual Studio should have something like the following example depending on your version of Visual Studio:

Congratulations, you've created an application that calls functions in your DLL. Now run your application to see what it does. On the menu bar, choose Debug > Start Without Debugging. Visual Studio opens a command window for the program to run in. The last part of the output should look like:

Press any key to dismiss the command window.

Now that you've created a DLL and a client application, you can experiment. Try setting breakpoints in the code of the client app, and run the app in the debugger. See what happens when you step into a library call. Add other functions to the library, or write another client app that uses your DLL.

When you deploy your app, you must also deploy the DLLs it uses. The simplest way to make the DLLs that you build, or that you include from third parties, available is to put them in the same directory as your app. It's known as app-local deployment.
