SAMPLE: Connect Net Drive--a File Manager Extension

Last reviewed: February 15, 1996

SUMMARY

The NETCON program sample demonstrates how to create a dynamic-link library (DLL) that will extend the File Manager application in Microsoft Windows versions 3.1 and later. The program sample exports a function called FMExtensionProc(), which File Manager sends messages to during its initialization. NETCON adds a Quick Connect menu to File Manager (in Windows for Workgroups, NETCON adds a toolbar button and a help string to be displayed in the status bar when the toolbar button is selected). When the Quick Connect menu item is selected, NECON.DLL brings up a Connect Network Drive dialog box. The program uses the following network application programming interface (API), which must be supported by the network that Windows is running on:

   - WNetAddConnection()
   - WNetGetConnection()

NETCON also maintains the MRU_Files section of WIN.INI in the exact manner that Windows for Workgroups does. Unlike the Connect Network Drive dialog box that comes with Windows for Workgroups, this dialog box does not browse for available drives during initialization, and therefore startup time may be significantly faster.

Download NETCON.EXE from the Microsoft Software Library (MSL) on the following services:
