How to Create DLL Files

by LaTasha Favors

Dynamic Link Libraries or DLL files are libraries of functions to which executable programs can link or refer to during run time. It serves as the central hub of tasks allowing easy access to different applications. It becomes a helpful tool for programmers and helps eliminate the need to create thousands of DLLs for every application. DLLs also allow easy debugging and upgrading.

Open Visual C++ and select "New" from the Project menu.

Set the project type as "Win32 Dynamic-Link Library (.dll)" or clear the check box that says "Use Microsoft Foundation Classes." If you wish to do so later, you can also view these options by choosing "Project" from Options menu.

Choose "Edit" from the Project menu. Use the dialog box that pops up and add the existing .C and .DEF files to the project. Alternately, you can enter the code directly in the Visual C++ editing window.

Choose the Build<yourname>.dll option from the Project menu to save your project.

Tip

  • check Other programs like Fortran, Pascal and Assemly can also be used to create DLL files.
