Is there a VISA interface for Delphi? (eventually written by a third party)?

Is there a VISA interface (VCL/DCU/PAS/BPL/...)
for Delphi?
I know that Delphi is not officially supported, but maybe some third party has wrote such a interface....

I don't personally use Delphi, but I seem to recall that it is not much trouble to call directly into any standard dll. Just use the C headers in "\win\include" to write your own import statements.
It really shouldn't be too hard, I did it for .NET.

There is also a VISA ActiveX that might work for you:

What is CWVISA?
CWVISA is an ActiveX control that abstracts the VISA API, so you can interface with serial, GPIB, and VXI instruments through interactive property pages and a simplified API. For example, use the CWVISA property pages to interactively find and communicate with your instruments, uncover interface problems, or verify communication with your instrument during design time. You can use the VISA ActiveX control in any ActiveX control container, including Microsoft Visual Basic, Visual C++, and Borland Delphi.

Tip: Refer to the Measurement Studio Reference for more information about Measurement Studio or the CWVISA control. You can launch the reference from your Windows Start menu.
