I'm using Indy 9 in BCB6. I can connect to a POP3 mailbox and find the
number of messages in my mailbox. I can cycle through the messages with
Retrieve() and read the subject of each message but I never get any
value for Flags (in the TIdMessage object, I'm checking for the value
mfRecent to see if a message has recently arrived but Flags is always =
0) even though I've sent a recent message to the mailbox. No matter how
many times I use this, I always get the same number for iMsg (the result
of CheckMessages()) and a value of 0 for NewMsgCount (because idm->Flags
is always = 0).
Here is my code (the ShowMessage() always shows the same, correct Subjects):
int NewMsgCount = 0;
Edit1->Text = String("Wait...");
Application->ProcessMessages();
IdPOP31->Connect();
int iMsg = IdPOP31->CheckMessages();
if( iMsg > 0 )
{
for( int iMsgNum = 1; iMsgNum <= iMsg; iMsgNum++ )
{
// also tried using 'this' instead of IdOPOP31
// in next instruction to no avail
TIdMessage *idm = new TIdMessage(IdPOP31);
idm->Clear();
if( IdPOP31->RetrieveHeader(iMsgNum, idm) )
{
if( idm->Flags.Contains(mfRecent) )
NewMsgCount++;
ShowMessage(idm->Subject); // always works
}
delete idm;
}
}
IdPOP31->Disconnect();
// display number of recent messages?
Edit1->Text = String(NewMsgCount);
Can anyone tell me what I'm doing wrong? Thank you.
