Create and delete a GPRS Access Point under Wm

Preface: when we develop the networking function on a mobile phone, we can use the access point set on the mobile phone to connect the mobile phone. However, sometimes the mobile phone settings may not be correct, in this case, if you still connect to the Internet using the mobile phone access point, there is an error in the program. We can create an access point on the mobile phone through the program, and then connect the network through the access point.

Create Access Point

void CCommunicate::CreateAccessPoint()   {           CString strFavoriteXml =                    L"<wap-provisioningdoc>"                    L"<characteristic type=\"CM_Networks\">"                  L"<characteristic type=\"Test_GPRS\">"                  L"<parm name=\"DestId\" value=\"{D1D06580-C364-55ec-9421-6ACF34129C58}\" />"                  L"</characteristic>"                  L"</characteristic>"                  L"<characteristic type=\"CM_GPRSEntries\">"                  L"<characteristic type=\"Test_GPRS\">"                  L"<parm name=\"DestId\" value=\"{D1D06580-C364-55ec-9421-6ACF34129C58}\" />"                  L"<characteristic type=\"DevSpecificCellular\">"                  L"<parm name=\"BearerInfoValid\" value=\"1\" />"                  L"<parm name=\"GPRSInfoValid\" value=\"1\" />"                  L"<parm name=\"GPRSInfoProtocolType\" value=\"2\" />"                  L"<parm name=\"GPRSInfoL2ProtocolType\" value=\"PPP\" />"                  L"<parm name=\"GPRSInfoAccessPointName\" value=\"cmwap\" />"                  L"<parm name=\"GPRSInfoAddress\" value=\"\" />"                  L"<parm name=\"GPRSInfoDataCompression\" value=\"1\" />"                  L"<parm name=\"GPRSInfoHeaderCompression\" value=\"1\" />"                  L"<parm name=\"GPRSInfoParameters\" value=\"\" />"                  L"</characteristic>"                  L"</characteristic>"                  L"</characteristic>"                  L"<characteristic type=\"CM_ProxyEntries\">"                  L"<characteristic type=\"WAP\">"                  L"<parm name=\"SrcId\" value=\"{D1D06580-C364-55ec-9421-6ACF34129C58}\" />"                  L"<parm name=\"DestId\" value=\"{436EF144-B4FB-4863-A041-8F905A62C572}\" />"                  L"<parm name=\"Proxy\" value=\"10.0.0.172:80\" />"                  L"<parm name=\"Enable\" value=\"1\" />"                  L"<parm name=\"Type\" value=\"1\" />"                  L"</characteristic>"                  L"</characteristic>"                  L"</wap-provisioningdoc>";             LPWSTR pszwXMLout = NULL;           HRESULT hr = DMProcessConfigXML(strFavoriteXml, CFGFLAG_PROCESS, &pszwXMLout);             if ( pszwXMLout )           {                   delete [] pszwXMLout;                   pszwXMLout = NULL;           }   }
