Hello Javier02,
Thank you for contacting National Instruments.
If I understand your question correctly, you are trying to perform data acquisition via ActiveX controls in Microsoft Access.
If you have LabVIEW, I would actually recommend writing a data acquisition VI (Virtual Instrument) in LabVIEW first. Then, attempt to use ActiveX controls to open and run LabVIEW within another program. If applicable, you may want to consider contacting Microsoft directly to determine exactly how to implement ActiveX controls within Access. The following example program will provide some guidance in calling LabVIEW from C++ using ActiveX:

I hope this points you in the right direction.
