I have a text file that I want to read line by line from into a string variable. On each click of a button I want to read the next line.Solutions I find reading from a textfile do it all at once though (in a while loop), displaying all lines on screen, but I don't want that. I want to fill one variable with the subsequent lines in the textfile, one at a time, everytime by a click on a button.How can I 'loop' through a textfile in this manner, without 'file already in use' errors etc.?
