How to use "write to spreadsheet" to save data when I want to?

[Perry_Liu]

No,  I mean before I click on the 'Quit' button. I want to save the data. So I click the print botton, but there is nothing, it seems that the print botton does not work.

You did not any code to save the data in the format you want. Modify the event. I have no way of knowing what format you want. The rest is simple - assuming you actually take the tutorial. I took you most of the way there. Your turn now.

Hi Dennis,

Thanks so much for your kind help these two days. I have to polish this program. Right now this program can measure the Voc, Isc, and efficiency of the solar cell. How to provide a botton that takes a quick measure of Isc and Voc and display the result next to the botton? I want to do this because I want to know the Voc and Isc before hand, so that I can set the range of scanning. In addition, I also want to set an initial delay time in seconds. Right now, the delay time is 3 seconds, I can not find where to set it, 3 seconds is default. I am looking through the tutorial, but I can not figure out. I think you can help me with it. Thanks.
