Hi Dominik,
It looks like your question on how to set up LabVIEW for ActiveX has been answered by the same question you posted in the LabVIEW General category:
http://exchange.ni.com/servlet/ProcessRequest?RHIVEID=101&RPAGEID=135&HOID=50650000000800000067450000&UCATEGORY_0=_49_%24_6_&UCATEGORY_S=0
Other resources available on ni.com for using LabVIEW and ActiveX can be found by typing in the keyword "activex" for your search query in the search box on a web page or by going to http://search.ni.com and using the search (or advanced search) from that page.
Regarding your question of whether or not the setup you described would be fast enough for real-time control, it depends on what constraints you have for your system. Typically, real-time control applications have specific time constraints on when an operation must begin or be completed. These applications typically run directly on the hardware (such as on an NI Real-Time DAQ board, where the program is downloaded to the hardware and runs on the board itself) or on a real-time, deterministic operating system. Deterministic means that the operating system can guarantee that an operation request will be serviced within a specific time frame. Concurrent PowerMAX is an example of a real-time operating system. Windows is not -- it cannot guarantee when an interrupt will be serviced after it is asserted. Typically, it is very likely it would have serviced the interrupt within 10ms, but because it is not deterministic, it could take longer than that. So depending on your specific time constraints on your applications, you would need to determine if the non-deterministic behavior for Windows could cause a problem. If Windows is an acceptable OS, then there is the actual task of benchmarking the system to see if the ActiveX layer will be fast enough for your process.
If you had questions specifically about the LabVIEW Real-Time module add-on, please post them in this category. Otherwise, I think you would find that you get the best results by posting in the LabVIEW General category.
Hope this tidbit of info helps. Good luck!
