Melvin,

Daniel has demonstrated how to add a connection via the API. Here's how to determine the connection name.

DECLARE INTEGER WNetGetConnection IN Win32API;
  STRING @lpszLocalName, STRING @lpbuffer, INTEGER @lnbufsize
lcdrive = "F:"
lnsize = 260
lcbuffer = SPACE(lnsize)
= WNetGetConnection(@lcdrive, @lcbuffer, @lnsize)
? LEFT(lcbuffer, lnsize - 1)

Naturally, you should check for the presence of the drive prior to issuing the calls. You can do this via the DRIVETYPE() function.

Easier, however, IMO is to use the Windows Script Host's WScript.Network object, like so:

oNet = CREATEOBJECT("WScript.Network")
oDrives = oNet.EnumNetworkDrives
FOR lni = 1 TO oDrives.Count - 1 STEP 2
  ? oDrives.Item(lni) && Display the share name
NEXT

The WSH, BTW, can also be used to map the drives for you. For details, see last December's issue of the VFUG newsletter. It's the fourth of a five part series that Ed Rauh and I wrote on the WSH. It's available on-line at www.vfug.org.
