Hello,

   How to add my Application Executable to Wndows Firewall Exception list automaticly, so that when my application runs on the machine for the first time it will add itself automaticly to windows firewall exception list without asking the user.

  Windows Automaticly blocks any application trying to use the Internet/LAN connections, and asks the user to Unblock ot Keep Blocking the application from accesing the connection.

  Some Users doesn't understand the message and click on KEPP BLOCKING, so that my application will not do its job.

The Jedi Windows Security Library contains a unit for controlling the Windows Firewall.
See http://blog.delphi-jedi.net/security-library/ and http://jwscldoc.delphi-jedi.net/index.html?frmname=topic&frmfile=JwsclFirewall_pas.html

I think you can use procedure AddToWinFirewall(ApplicationFilename: TJwString; NameOnExeptionlist: TJwString; EnableRule: Boolean);

I think it is easier than using Outside laibraries.
   Some API functions should solve the story.

Then you need to import the typelib (from %windir%\system32\hnetcfg.dll ) and implement yourself.
Documentation of the interfaces is here: http://msdn.microsoft.com/en-us/library/aa366452(VS.85).aspx

I found this and it's worked :
uses ActiveX, ComObj;
 

const

   NET_FW_PROFILE_DOMAIN = 0;

   NET_FW_PROFILE_STANDARD = 1;

   NET_FW_IP_VERSION_ANY = 2;

   NET_FW_IP_PROTOCOL_UDP = 17;

   NET_FW_IP_PROTOCOL_TCP = 6;

   NET_FW_SCOPE_ALL = 0;

   NET_FW_SCOPE_LOCAL_SUBNET = 1;

 
 

procedure AddPortToFirewall(EntryName:string;PortNumber:Cardinal);

var

  fwMgr,port:OleVariant;

  profile:OleVariant;

begin

  fwMgr := CreateOLEObject('HNetCfg.FwMgr');

  profile := fwMgr.LocalPolicy.CurrentProfile;

  port := CreateOLEObject('HNetCfg.FWOpenPort');

  port.Name := EntryName;

  port.Protocol := NET_FW_IP_PROTOCOL_TCP;

  port.Port := PortNumber;

  port.Scope := NET_FW_SCOPE_ALL;

  port.Enabled := true;

  profile.GloballyOpenPorts.Add(port);

end;
 

procedure AddApplicationToFirewall(EntryName:string;ApplicationPathAndExe:string);

var

  fwMgr,app:OleVariant;

  profile:OleVariant;

begin

  fwMgr := CreateOLEObject('HNetCfg.FwMgr');

  profile := fwMgr.LocalPolicy.CurrentProfile;

  app := CreateOLEObject('HNetCfg.FwAuthorizedApplication');

  app.ProcessImageFileName := ApplicationPathAndExe;

  app.Name := EntryName;

  app.Scope := NET_FW_SCOPE_ALL;

  app.IpVersion := NET_FW_IP_VERSION_ANY;

  app.Enabled :=true;

  profile.AuthorizedApplications.Add(app);

end;

Open in new window
