I am trying to make a file write to disk and this code compiles fine. The save dialog box appeares and you can use it normally, but when you press save, nothing happens. Does anybody know the right way(as opposed to my way) of doing this? Thanks.

      import java.awt.*;

      g.drawString("You have just typed " + String.valueOf(currentChar), 1, 50);

in your code, you have this:

out.writeObject("fosString");

I am suspicious of the double quotes. in double quotes you get the literal string "fosString"

in order to write out the object refered to by the fosString handle, you do not want to use the double quotes.

Dang, I tried it and it gave me an error about that object not existing so it does recognize the string as a reference to an object. On comp.lang.java.help someone wrote to me on the same topic. It all sounds like greek to a newbie like myself, but it looks kinda like it makes sense. Any ideas on this? Thanks.

Never mind, I was stupidly trying to execute it as an applet rather than an application. After I made it an application it worked just fine. Thanks anyway.
