They install with Measurement Studio or NI-DAQ. You need to install ComponentWorks from the Measurement Studio CD or install Visual Basic support from NI-DAQ.

Hi Chris,
Thanks.
When i compile your prog, i have an error: can't open file niall.h.
Where can i found it?
You said in your last answer that i need to install ComponentWorks from the Measurement Studio CD. I haven't this CD. Do you know if NI give this CD free.
Have a good day.

That example is written with Measurement Studio. Measurement Studio includes development tools for for ANSI C, Visual C++, and Visual Basic developers. That is what this discussion forum is setup for so I mistakenly assumed you had it. The DAQ ActiveX controls are the only controls that are available for free. All the rest of them (User Interface, Analysis, etc.) are included in Measurement Studio. Since you don't have it, then you can't use the example I sent, but you can still use the CWAI control. Add the control to a project and then you can look at the example's CPP file to see how it is used.
