Daniel,
The function call is fh_FdbMsgQuery. The structure is shown below. It's
defined in <aimhistorian.h>. It's been a while since I used it but I have a
sample program which I can send you off list.
fh_FdbMsgQuery(historian, m_tmEndTime, m_tmStartTime, filter,
(char*)ptr_hdr, lbody, &more, &reterr);

Subject: [foxboro] Retrieving String Values with AIM*API
We are wondering if anyone has experience using AIM*API with Visual
Studio 6.0 to talk to AIM*Historian in the C language. We are running
an off-platform historian on a Windows 2000 box. We can use the
an_hist_values() function or Fh_FdbGetValues() function to retrieve
floating point values from the database. However, we can't seem to find
a function to read string values. Clearly it can be done using the
Excel interface or OLEDB, but what about function calls from the C
language? Thanks for any help you can give.
