ssl certificate - Indy POP3 with invalid cert -


i have pop3 client uses indy, connects need abort connection when certificate invalid. have ideas?

procedure tpop3client.connectpop3;  var  status : boolean;  i, msgtotal : integer; begin  if edssl begin   pop3.iohandler := ssl;   pop3.usetls := utuseexplicittls;  end;  status := false;  try   pop3.username := edusername;   pop3.password := edpassword;   pop3.connect(edtargethost,edtargetport);   if pop3.connected begin      msgtotal := pop3.checkmessages;      if  msgtotal >=1       := 1 msgtotal begin        if getmessage(i)         begin           getheaders;           delmessage(i)         end;   end  end;    pop3.disconnect  end; end;

in tidssliohandlersocketopenssl component, enable sslvrfpeer flag in ssloptions.verifymode property, , optionally assign handler onverifypeer event if want validate particular details of server's certificate beyond openssl's default validations. if validation fails, ssl/tls handshake terminated error alert, connection closed, , exception raised code.

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
