I'm working on a program takes an address and then there is an array of 99 textboxes. I would like to be able to save the file as my own filetype and be able to open it back up to have the address and the textboxes already filled out. I am searching for a way to do that, but all I end up with is a lame CD control example that just saves txtBox1.text and the opens the file into txtBox1.text. Would I have to create an ini file? I woud like it to have an extention just for my program, so if you double click the file, my program opens.
