As you maybe alreay know, Dlls (Dynamic Link Libraries) provide developers with functions which they can work with.
These functions need to be imported at compile-time which is automatically done by delphi.
Now, the problem is, that the function "AdsGetDataLength" doesnt exist in that
dll you are trying to import it from! Thus you get the error-message!
I guess you are using different versions of "ACE32.dll".
One possible solution: Use the proper version of the
dll. Include it in your executable's directory!
But then you would have to ship out both the exe and the
dll.
