Having trouble using setText() for RichTextField and other GUI issues.
I'm having trouble with two things of immediate concern
1.) I cannot figure out how to read in text from a file, at least to able to read in line breaks like
"bla bla bla bal
bla bla bla bla"
and also to be able to set the text. It's complaining that I cannot convert from std::String to System::String. What does the L label stand for?
2.) I don't know how to reference and load other forms in a form. For instance if I have window1 and I want it to have a button that will open window/form 2, how do I do that? I think the click action or whatever is the equivalent of a java ActionListener. Anyway, I've tried that without success. Right now, I'm working on the readin.
Code:
