Hello Leo,
As msaxon mentioned, it might be easier to use either the built in timer control in CVI or the async timer functions.
You can find a timer example program in the following directory: ...MeasurementStudio\cvi\samples\userint\timer.prj
You can find an async timer example program in the following directory: ...MeasurementStudio\cvi\samples\toolbox\asyncdemo.prj
If you want to use the Borland C++ Builder control and functions, you can consider somehow packaging all your functions, etc. together in a dll. I'm not sure if this is possible, but if it is, then you could create an import library from the DLL header file in CVI. But it's important to note that since CVI is a C compiler and not C++, using C++ data types or programming techniques (function overloads, etc.) will not work.
Thanks.
