Hello, everybody greatly
I recently because the need, useful to the headless signal hound API
His Library and DLL are produced by vc + + 2008, I have to use vc + + 2008 tried
Can the normal use, but because of only using BCB 6, so a simple call to action is always wrong,
Hope to have experience greatly can advise
I also used the lib and DLL implib way but will appear the following error messages: always open files.
I am confirm my path is right
Here are the API header file
MySignalhound. H

 
Revision History (Windows) : 
12 JAN 2012, Mr Crooks Created from Signal Hound code, Removed the Windows dependencies. 
19 APR 2012, Mr Crooks Added AD9864 recalibration support and cleaned up a bit
