一个简单的办法就是你自己写一个小程序代替Windows的映射。。
function ConnectDrive(_drvLetter: string;
_netPath: string;
_showError: Boolean;
_reconnect: Boolean): DWORD;
var
nRes: TNetResource;
errCode: DWORD;
dwFlags: DWORD;
begin
{ Fill NetRessource with #0 to provide uninitialized values }
FillChar(NRes, SizeOf(NRes), #0);
nRes.dwType := RESOURCETYPE_DISK;
{ Set Driveletter and Networkpath }
nRes.lpLocalName := PChar(_drvLetter);
nRes.lpRemoteName := PChar(_netPath);
{ Example: //Test/C }
{ Check if it should be saved for use after restart and set flags }
if _reconnect then
dwFlags := CONNECT_UPDATE_PROFILE and CONNECT_INTERACTIVE
else
dwFlags := CONNECT_INTERACTIVE;
errCode := WNetAddConnection3(Form1.Handle, nRes, nil, nil, dwFlags);
{ Show Errormessage, if flag is set }
if (errCode <> NO_ERROR) and (_showError) then
begin
Application.MessageBox(PChar('An error occured while connecting:' + #13#10 +
SysErrorMessage(GetLastError)),
'Error while connecting!',
MB_OK);
end;
Result := errCode;
{ NO_ERROR }
end;
function DisconnectNetDrive(_locDrive: string;
_showError: Boolean;
_force: Boolean;
_save: Boolean): DWORD;
var
dwFlags: DWORD;
errCode: DWORD;
begin
{ Set dwFlags, if necessary }
{ Setze dwFlags auf gewünschten Wert }
if _save then
dwFlags := CONNECT_UPDATE_PROFILE
else
dwFlags := 0;
{ Cancel the connection see also at http://www.swissdelphicenter.ch/en/showcode.php?id=391 }
errCode := WNetCancelConnection2(PChar(_locDrive), dwFlags, _force);
{ Show Errormessage, if flag is set }
if (errCode <> NO_ERROR) and (_showError) then
begin
Application.MessageBox(PChar('An error occured while disconnecting:' + #13#10 +
SysErrorMessage(GetLastError)),
'Error while disconnecting',
MB_OK);
end;
Result := errCode;
{ NO_ERROR }
end;
{映射网络驱动器}
procedure TForm1.Button1Click(Sender: TObject);
begin
ConnectDrive('O:', '//SERVER/C$', True, True);
end;
{断开网络驱动器}
procedure TForm1.Button2Click(Sender: TObject);
begin
DisconnectNetDrive('M:', True, True, True);
end;
