I have a .csv file saved with firstname, lastname, address, phone informantion. when form is loaded, the firstname and last name will be loaded into a list box, the address and phone will be loaded into an array, when i click a name in the list box, all information about this person will be populated into four text boxes, then i do some changes in the text boxes. How can i save these information back to .csv file and replace the original one.


Thanks
