It is very easy to get a list of all the network drive mappings using the following function. Please note that you must
create and
free the string list that you pass to it. The return value indicates the number of network mappings
GetNetworkDriveMappings() was able to find.
function GetNetworkDriveMappings(
sl : TStrings ) : integer;
var
i : integer;
sNetPath : string;
dwMaxNetPathLen : DWord;
begin
sl.Clear;
dwMaxNetPathLen := MAX_PATH;
SetLength( sNetPath,
dwMaxNetPathLen );
for i := 0 to 25 do
begin
if( NO_ERROR =
Windows.WNetGetConnection(
PChar(
'' + Chr( 65 + i ) + ':' ),
PChar( sNetPath ),
dwMaxNetPathLen ) )then
begin
sl.Add( Chr( 65 + i ) + ': ' +
sNetPath );
end;
end;
Result := sl.Count;
end;
//
// here's how to call GetNetworkDriveMappings():
//
var
sl : TStrings;
nMappingsCount,
i : integer;
begin
sl := TStringList.Create;
nMappingsCount :=
GetNetworkDriveMappings( sl );
for i := 0 to nMappingsCount-1 do
begin
//
// do your thing here...
// for now, we'll just display the mapping
//
MessageBox( 0,
PChar( sl.Strings[ i ] ),
'Network drive mappings',
MB_OK );
end;
sl.Free;
end; |
If you need to programmatically map and delete network drives, look up
WNetAddConnection(),
WNetAddConnection2(),
WNetAddConnection3(),
WNetCancelConnection(), and
WNetCancelConnection2() in your "Win32 Programmer's Reference."
