"Just a quick one to say I'm very impressed so far :) The documentation for developers is excellent and I've quickly managed to get an app written to do historical downloads. The system is very robust and pretty quick considering the extent of data that's available. The support guys have been very helpful too, in combination with the forums it's been plain sailing so far!" - Comment from Adam

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
