A Dynamic-link library (DLL) file is a library which consists of code and data that may be used by more than one program at the same interval of time. For example, in Windows, the Comdlg32 DLL performs common dialog box related functions.
So, any other program can use the same functionality that is contained in this DLL to implement an Open dialog box. The use of DLL efficiently promotes code reuse and efficient memory usage. Follow the steps provided in this tutorial to register a dll file on Windows 8.
Properly Register DLL files
1. On your Metro Start Screen, move to your mouse cursor to the lower left screen to open the Windows 8 charm. Next, click on Search.
2. Next, type CMD in the Search App box. Right click on the CMD icon on the left side. Then you will see Advanced on the bottom.
3. Next, click on the Advanced and select Run as administrator.
4. Now locate the dll file you want to register. cd drive name will change to the directory / folder where your dll file is. dir/w will list the files inside the drive / directory / folder. http://www.dll-files.com/ is one of the free site which offers almost all the dll files.
5. Next, type regsvr32 [dll file name]. For example – in my screenshot i have registered SelectAll.dll so i typed regsvr32 SelectAll.dll
65. Finally, you will see a message saying registering dll file succeeded. The message would be like DllRegisterServer in [your dll file name] succeeded. That are the complete steps to register dll file on Windows 8.
The main advantages of using DLL file are, it uses fewer resources, promotes modular architecture, eases deployment and installation. In short, using DLL simplify things. We all know there are many components like menu bar, open dialog box which are common to a lot of software. Most application needs to create a graphical interface (GUI) that appears on the screen. Instead of using a separate code to create the interface themselves, the application calls on a DLL for that function from the OS (Windows). This saves resources, size and more.
