I have a quick question and I apologise for my ignorance if it is easy to perform. I have a GUI class which takes 3 peices of information from the user in text fields which are loaded into 3 variables. I then want to click a 'Run' button and place the information from the variables at three defined points in a text file. Basically a user enters some information to the GUI, clicks RUN and a predefined text file containing some data and three variables has each of the variables updated to reflect user input? First, is this possible? If so, where do I start? I was thinking put three variables in the text file: @variableA @variableB @variableC I these will updated (like find and replace) using the Ruby GUI. Thanks in advance. -- Posted via http://www.ruby-forum.com/.
