"There is no doubt that IQFeed is the best data provider. I am very satisfied with your services. And IQFeed is the only one that I would recommend to my friends. Now, most of them are using your product in China." - Comment from Zhezhe

"Boy, probably spent a thousand hours trying to get ******* API to work right. And now two hours to have something running with IQFeed. Hmmm, guess I was pretty stupid to fight rather than switch all this time. And have gotten more customer service from you guys already than total from them… in five years." - Comment from Jim

"I have been using IQFeed now for a few years in MultiCharts and I have zero complaints. Very, very rare to have any data hiccups or anything at all go wrong." - Comment from Public Forum

"I just wanted to say how happy I am with your service. I was able to download the API docs last week and I was able to replicate Interactive Brokers historical bar queries and realtime bar queries over the weekend. That was about one of the fastest integrations that I've ever done and it works perfectly!!!!" - Comment from Jason via Email

"I've been using IQFeed 4 in a multi-threaded situation for the last week or two on 2600 symbols or so with 100 simultaneous daily charts, and I have had 100% responsiveness." - Comment from Scott

Author	Topic: Historical data requests in 64-bit VBA (8 messages, Page 1 of 1)
jonnyb -DTN Evangelist- Posts: 122 Joined: Aug 15, 2012	Posted: Aug 6, 2013 09:13 AM Msg. 1 of 8 Hello, About a year ago I posted about retrieving historical data in VBA. At the time, some upgrades needed to happen to the client before it would work, but the bigger issue was that it was only 32-bit compatible. Is it now possible to do it in Excel 2010 64-bit?
DTN_Steve_S -DTN Guru- Posts: 2093 Joined: Nov 21, 2005	Posted: Aug 6, 2013 09:28 AM Msg. 2 of 8 Unfortunately our COM interfaces are only available via 32bit binaries which makes them inaccessible to 64bit applications. COM is the only way to get the data into VBA natively. Alternatively, you can use sockets to communicate with IQFeed across the 32bit/64bit application boundries but socket libraries/implementations for VBA are pretty few and far between.

We have moved farther away from COM since the earlier posts. while it is there for backwards compatibility, we are not doing adding any new COM functionality. Based on this I would try to stick to the socket code outlined in the current documentation. Tim
