Hi Prahteek,

I think I suggested to use a ValueChange event for the combobox already in the other thread…

HI GerdW

I am sorry..... but i couldn't see anything related to value change event in the previous threads. I think i have to use value change event for assignig of pin definition when it displays the value of spreadsheet, but firstly how could I link items in dropdown list of combobox to the spreadsheet files ? Could you please help me.....

Hi Pratheek,

Take a look at the attached vi. It may help you in going forward. I would strongly advice you to study the basics of Event structures and their usages. It is going to be handy if you are planning to make good  LV projects.

Just to make my doubt a bit more clear, I am attaching the two snapshots below.....the 1st snapshot is the data from the spreadsheet and 2nd snapshot is of the assigned values to the pin numbers manually........could you please tell me how could I save these changes done to the spredsheet in a new .csv file

Hi Pratheek,

use WriteSpreadsheetFile to save that array to a CSV file…
