关于WM下创建和删除GPRS接入点

序言：当我们在手机上开发联网功能时，可以使用手机上设置好的接入点实现手机联网，但是有时候手机的设置不一定会正确，这时如果还是以手机的接入点来联网，程序有出错，我们可以通过程序在手机上创建接入点，然后再通过该接入点进行联网。

创建接入点

void CCommunicate::CreateAccessPoint()   
{   
        CString strFavoriteXml =    
                L"<wap-provisioningdoc>"

        LPWSTR pszwXMLout = NULL;   
        HRESULT hr = DMProcessConfigXML(strFavoriteXml, CFGFLAG_PROCESS, &pszwXMLout);   
  
        if ( pszwXMLout )   
        {   
                delete [] pszwXMLout;   
                pszwXMLout = NULL;   
        }   
} 

使用创建的接入点

int CCommunicate::CreateConnection( HANDLE *phConnection )   
{   
        HRESULT            hResult;   
        //        HANDLE             phConnection;   
        DWORD              dwStatus;    
        DWORD              dwResult;   
        CONNMGR_DESTINATION_INFO cdi;   
        int i;   
        for(i = 0; SUCCEEDED(ConnMgrEnumDestinations(i, &cdi)); i++)   
        {   
                if (0 == wcscmp(cdi.szDescription, _T("Test_GPRS")))   
                        break;   
        }   
        hResult = ConnMgrEnumDestinations(i, &cdi);   
        if (FAILED(hResult))   
        {   
                AfxMessageBox(L"ConnMgrEnumDestinations Error!");   
                return FALSE;   
        }   
        CONNMGR_CONNECTIONINFO ConnInfo;    
        ZeroMemory( &ConnInfo, sizeof( ConnInfo ) );    
        ConnInfo.cbSize = sizeof( ConnInfo );    
        ConnInfo.dwParams = CONNMGR_PARAM_GUIDDESTNET;    
        ConnInfo.dwPriority = CONNMGR_PRIORITY_HIPRIBKGND;    
        ConnInfo.dwFlags = CONNMGR_FLAG_PROXY_HTTP | CONNMGR_FLAG_PROXY_WAP;   
        ConnInfo.bExclusive = FALSE;            
        ConnInfo.bDisabled = FALSE;    
        ConnInfo.guidDestNet = cdi.guid;   
        TRACE(_T("ConnectToHttpServer\n") );   
  
        dwStatus = CONNMGR_STATUS_CONNECTED;   
  
        hResult = ConnMgrEstablishConnectionSync( &ConnInfo, phConnection, 75000, &dwStatus );   
        if ( hResult != S_OK )   
        {

                dwResult = GetLastError();   
                // for debug   
                CString tmp;   
                tmp.Format(_T("%ld"), dwStatus);   
                AfxMessageBox( tmp, MB_OK);

        else  
        {

                // do something   
        }   
        return S_OK;   
} 

删除创建的接入点

void CCommunicate::ReleaseAccessPoint()   
{   
        CString strFavoriteXml =    
                L"<wap-provisioningdoc>"  
                L"<characteristic type=\"CM_Networks\">"  
                L"<nocharacteristic type=\"Test_GPRS\"/>"  
                L"</characteristic>"    
                L"</wap-provisioningdoc>";   
        LPWSTR pszwXMLout = NULL;   
        HRESULT hr = DMProcessConfigXML(strFavoriteXml, CFGFLAG_PROCESS, &pszwXMLout);   
  
        if ( hr == S_OK)   
        {   
                AfxMessageBox( L"Delete access point success!");   
        }   
        else  
        {   
                AfxMessageBox( L"Delete access point failed!");   
        }   
        if ( pszwXMLout )   
        {   
                delete [] pszwXMLout;   
                pszwXMLout = NULL;   
        }
