how to create event driven 'write to excel .vi'

[altenbach]

Since the while loop spins anyway, you should replace the event structure with a simple case structure. That's all you need.

Thanks for replying I tried that too but is almost the same result. I tried a Case structure. When i ran it. The preogram starts to ask me file path again and again after every loop, so i gave it a default file path and gave it instruction to delete file data every time the loop runs but really what i want is that the data continues to be written where it stopped in the first loop. I want a way to collect data without overwriting actually, in the same file. Please help!!!

You need to make sure that there is a valid file path in the "file path" control. Is there?

If you want to append to an existing file, keep the file path in a shift register and set append=true of the write VI.

Hello troy, 

Please could you help me find a way to use the posted VI to  start the timer when a condition is met (as for example when the voltage of a signal crosses a certain value). 

Actually I tried wiring a control button in the some way to start the timer but it didn't work. kindly let me know how I can deal with this issue. ( I am not sure how to use the event structure). Please find attached the modified (not working) VI. 

Thanks a lot!

There are many VIs posted above, please clarify which one you mean. Troy did not post any VIs.

This is an old thread, so I would suggest to start a new one.

THere is no attachment. Attach your VI so can see what's wrong.
