Hi all!

I'm trying to get data over DDE channel from IQLink. C++\WinAPI.

::DdeConnect passes without errors, but ::DdeClientTransaction returns an error 0x4009 (DMLERR_NOTPROCESSED).


HSZ hszField = ::DdeCreateStringHandle(dwIDInst, "Exp Date", CP_WINANSI);

DWORD nDDERes = 0;
HDDEDATA hData = ::DdeClientTransaction(NULL, 0, hConv, hszField, CF_TEXT, XTYP_REQUEST, 1500, &nDDERes);
// hData is null
// DdeGetLastError returns DMLERR_NOTPROCESSED


What am I doing wrong?
IQFeed v5.1.1.3

Can I get the exact expiry date by the symbol from other channel (TCP\COM)?

Good morning,

We do have TCP options available that I think will meet your needs. But, we do not have development support for DDE. Do you have a development account with us currently? If you do, you can access the expiration date via our Fundamental data message. It is located here, http://www.iqfeed.net/dev/api/docs/Level1FundamentalMessage.cfm. You will have to be logged in for the page to work.

If not, you would want to reach out to our sales team so we can help to get you signed so we can help move you forward.

Tim

Good morning Tim!

Yes, we have development account, and I see the page 'Fundamental Message Format'.

Ok, thank you! I'l try this way.

Tim, good morning!

Can you help me compose a fundamental message to get the symbol expiration time? I can not understand from the help page how to compose it. For example, symbol @ADN18.
And what interfaces do I need to use, ILevelOneGeneral2 will be sufficient?

Anytime you issue a watch to a server, a Fundamental message will be returned.

The COM interfaces, while they have remained functional for backwards compatibility are no longer receiving updates, so I would recommend using the current socket based code that is used in our samples for any new development.

I'll send you an email with some additional details.

Tim

I can't reply to your letter, in response to sending the letter I received:

Can you log into the dev site and then click on the chat icon? Then at least I can get you going while I research the other.

Ok, just wanted to be sure you were not in another country doing business, I can imagine that it may be related to your local IP address rather than your mail servers.

It's unlikely that this is due to my local IP address, i tried to send you an email via the web site mail.ru

Tim, good morning!

I downloaded and installed the latest version of the API (instead v5.1.1.3).

Which port do i need to connect with telnet, that would get data on the symbol expiration time?

It seems to have happened :)

I sent 'w@ADN18' to port 5009, and i received a fundamental message about this symbol.

I think, the problem is solved, thank you! :)
