大家開(kāi)發(fā)網(wǎng)絡(luò)程序,經(jīng)常要連接其他主機(jī),如果在xp上運(yùn)行,一定會(huì)提示你,只有選擇解除阻止才能實(shí)現(xiàn)正常的網(wǎng)絡(luò)連接.那么有沒(méi)有辦法在防火墻的例外列表里面通過(guò)編程的方式加入自己的程序呢?
當(dāng)然有了,不然就不要介紹了
xp的系統(tǒng)目錄下面有個(gè)hnetcfg.dll就是這個(gè)編程接口,頭文件是netfw.h,初始化代碼如下:
INetFwProfile* m_pFireWallProfile=NULL;
HRESULT hr = S_FALSE;
INetFwMgr * fwMgr = NULL;
INetFwPolicy * fwPolicy = NULL;
FW_ERROR_CODE ret = FW_NOERROR;
try
{
if ( m_pFireWallProfile )
throw FW_ERR_INITIALIZED;
// Create an instance of the firewall settings manager.
hr = CoCreateInstance( __uuidof(NetFwMgr), NULL, CLSCTX_INPROC_SERVER, __uuidof( INetFwMgr), ( void ** ) & fwMgr );
if ( FAILED( hr ))
throw FW_ERR_CREATE_SETTING_MANAGER;
// Retrieve the local firewall policy.
hr = fwMgr -> get_LocalPolicy( & fwPolicy );
if ( FAILED( hr ))
throw FW_ERR_LOCAL_POLICY;
// Retrieve the firewall profile currently in effect
hr = fwPolicy -> get_CurrentProfile( & m_pFireWallProfile );
if ( FAILED( hr ))
throw FW_ERR_PROFILE;
}
catch ( FW_ERROR_CODE nError)
{
ret = nError;
}
if ( fwPolicy )
fwPolicy -> Release();
if ( fwMgr )
fwMgr -> Release();
return ret;
將程序名稱加入例外列表:
WinXPSP2FireWall::AddApplication( const wchar_t* lpszProcessImageFileName, const wchar_t* lpszRegisterName )
{
FW_ERROR_CODE ret = FW_NOERROR;
HRESULT hr;
BOOL bAppEnable;
BSTR bstrProcessImageFileName = NULL;
BSTR bstrRegisterName = NULL;
INetFwAuthorizedApplication* pFWApp = NULL;
INetFwAuthorizedApplications* pFWApps = NULL;
try
{
if( m_pFireWallProfile == NULL )
throw FW_ERR_INITIALIZED;
if( lpszProcessImageFileName == NULL || lpszRegisterName == NULL )
throw FW_ERR_INVALID_ARG;
// First of all, check the application is already authorized;
FW_ERROR_CODE nError = this->IsAppEnabled( lpszProcessImageFileName, bAppEnable );
if( nError != FW_NOERROR )
throw nError;
// Only add the application if it isn't authorized
if( bAppEnable == FALSE )
{
// Retrieve the authorized application collection
hr = m_pFireWallProfile->get_AuthorizedApplications( &pFWApps );
if( FAILED( hr ))
throw FW_ERR_AUTH_APPLICATIONS;
// Create an instance of an authorized application
hr = CoCreateInstance( __uuidof(NetFwAuthorizedApplication), NULL, CLSCTX_INPROC_SERVER, __uuidof(INetFwAuthorizedApplication), (void**)&pFWApp);
if( FAILED( hr ))
throw FW_ERR_CREATE_APP_INSTANCE;
// Allocate a BSTR for the Process Image FileName
bstrProcessImageFileName = SysAllocString( lpszProcessImageFileName );
if( SysStringLen( bstrProcessImageFileName ) == 0)
throw FW_ERR_SYS_ALLOC_STRING;
// Set the process image file name
hr = pFWApp->put_ProcessImageFileName( bstrProcessImageFileName );
if( FAILED( hr ) )
throw FW_ERR_PUT_PROCESS_IMAGE_NAME;
// Allocate a BSTR for register name
bstrRegisterName = SysAllocString( lpszRegisterName );
if( SysStringLen( bstrRegisterName ) == 0)
throw FW_ERR_SYS_ALLOC_STRING;
// Set a registered name of the process
hr = pFWApp->put_Name( bstrRegisterName );
if( FAILED( hr ))
throw FW_ERR_PUT_REGISTER_NAME;
// Add the application to the collection
hr = pFWApps->Add( pFWApp );
if( FAILED( hr ))
throw FW_ERR_ADD_TO_COLLECTION;
}
}
catch( FW_ERROR_CODE nError )
{
ret = nError;
}
SysFreeString( bstrProcessImageFileName );
SysFreeString( bstrRegisterName );
if( pFWApp )
pFWApp->Release();
if( pFWApps )
pFWApps->Release();
return ret;
}
