All the objects lie in %windir%\system32\hnetcfg.dll You'll need to import
the type library for that in order to have a .pas file you can work with.
With Delphi 6 I had to use the command-line importer tlibimp.exe in the D6\Bin
dir, because the interfaces you want are in the 3rd "section" (don't know the
proper term) of the DLL file, and the GUI importer wouldn't let me add the \3
after the DLL name in the file browser without choking.
After running that, you should have a NetFwTypeLib_TLB.pas file (and a .dcr as
well, but I haven't needed that). Check MSDN (msdn.microsoft.com) for the
INetFwMgr interface for more info, but the following code will add a port.
Note the account in question must be an Administrator, or the calls will fail.
I've tested this, and not even Power Users can open/modify ports (a good thing).
const
FW_MGR_CLASS_NAME = 'HNetCfg.FwMgr';
FW_OPENPORT_CLASS_NAME = 'HNetCfg.FwOpenPort';
function XPFirewallAddPort(APort: Integer; AName: String;
AProtocol: NET_FW_IP_PROTOCOL_ = NET_FW_IP_PROTOCOL_TCP;
AScope: NET_FW_SCOPE_ = NET_FW_SCOPE_ALL; AEnabled: Boolean = True;
AIPVersion: NET_FW_IP_VERSION_ = NET_FW_IP_VERSION_ANY): HRESULT;
var
FwMgrDisp: IDispatch;
FwMgr: INetFwMgr;
FwProfile: INetFwProfile;
FwOpenPortDisp: IDispatch;
FwOpenPort: INetFwOpenPort;
begin
Result := S_OK;
try
FwMgrDisp := CreateOleObject(FW_MGR_CLASS_NAME);
try
FwMgr := INetFwMgr(FwMgrDisp);
FwProfile := FwMgr.LocalPolicy.CurrentProfile;
FwOpenPortDisp := CreateOleObject(FW_OPENPORT_CLASS_NAME);
try
FwOpenPort := INetFwOpenPort(FwOpenPortDisp);
with FwOpenPort do
begin
Port := APort;
Name := AName;
Protocol := AProtocol;
Scope := AScope;
Enabled := AEnabled;
IpVersion := AIPVersion;
end;
FwProfile.GloballyOpenPorts.Add(FwOpenPort);
finally
FwOpenPortDisp := Unassigned;
end;
finally
FwMgrDisp := Unassigned;
end;
except
on E:EOleSysError do
begin
Result := E.ErrorCode;
end;
end;
end;
