Thank you for your help but I have tried all the suggestions above.
My problem is that I think ; when I am trying to download, compile and run the "block diagram constructed on labview " into NXT a warning becomes saying that the VI is password protected.
I think it means that NXT device cannot understand labview 's special blocks that's why this error appears on the screen ....????
Instead I think I need to use the blocks in the NXT Toolkit special for Lego NXT in order to store the data.
However,the data will be stored not on the PC but in the NXT memory.Later I can send it to copmputer.
Is there a direct way to store the sensor data using labview (the sensor is connected to NXT) ?
Thank you
