View 3 RepliesI'm fairly inexperienced with VB but have been trying to get "save" functionality out of a program I'm trying to write. Basically I have a Datagridview and I want to write each line from the grid into a .txt file. So what I've been trying to do is use Datagridview.Items and then variables as column / row indexes to move cell by cell left to right , writing each cells data to an array which also increments along the way. Then using WriteLine to write the array to the text file, zero'ing all the counters then starting all over again for the next row.... make sense?
