Modules & VBA :: Temporarily Map A Drive / Copy A File Then Remove Mapped Drive

My workaround was to temporarily map the URL to a vacant drive letter on the local machine, then copy the file over, then drop the mapped drive again. A bit clunky but doesn't incorporate much of a delay and this download only has to happen once per day.

The good news is, the file download / copy now works every time. The bad news is that removing the temporarily mapped drive after the copy has taken place, doesn't and I can't figure out why.

Here are the functions I use to map / unmap the drive :

Code:

Option Compare Database
Option Explicit

Private Const RESOURCETYPE_ANY = &H0&
Private Const CONNECT_UPDATE_PROFILE = &H1&
Private Const RESOURCE_CONNECTED As Long = &H1&

[Code] .....

I have separate functions to check existing drive mappings on the local machine and thus determine an appropriate vacant letter to use for the temporary mapping - they work fine.

Unfortunately the UnMapDrive function returns False (even though I switch the active drive to C: and force the connection to be cancelled with the fForce flag) So the mapping always remains on the users profile.

I don't want to permanently map drives on the users' profiles, just briefly for the purposes of this daily file download.
