SUMMARY
Advanced: Requires expert coding, interoperability, and multiuser skills.
The following steps describe how to call C++ dynamic-link library (DLL) functions in Access Basic:
Make sure to define the functions within your C++ code with the "extern" declaration. The following example demonstrates the syntax for the extern declaration:
extern "C" {return type} FAR PASCAL __export {function name} ({parameters})
An example of an actual declaration in your C++ code might look like:
extern "C" int FAR PASCAL __export my_func ()
To call the sample function above you would define the Declare statement as follows:
Declare Function my_func Lib "MYLIB.DLL" () As Integer- Make sure that the declaration is not set for case-sensitive exports.
