Implementing the Protocol Handler Interfaces

Implementing the Protocol Handler Interfaces

Creating a custom protocol handler requires implementing dynamic-link library (DLL) export functions that perform protocol handler registration. For more information about creating DLLs for Windows 2000, see the Microsoft Win32® application programming interface (API) section of the Microsoft Platform SDK.
