in Handling Errors section in the spec, it doesnt show an example of using the try catch finally keywords. Is it somewhere else? Surely that would be the right place to put it.

can someone post an example for using the finally keyword, because C++ doesnt use it.

You should be able to implement a Singleton pattern
easy.
This is what I do in Java

public class One{
    One one;

public static void getOne(){
        if(one == null){
              new One();
            }
    }

private One(){ // private constructor
   //construct stuff
}

}

This way if there is an instance of One already
you cannot make another One.

This was good for me in Java because I found
that when clicking a JTable for some reason the
Thread goes through the event listener method
twice.

The Singleton pattern solved this problem for
me.


Phill.

I probably know less about error handling than you do, so my example may be of limited use (or wrong).  But the attached example does compile and run and it may answer your question.  If it doesn't help you, you might try to re-phrase your question.  More specific questions get more specific answers.

By the way, I'm assuming you've already looked at http://www.digitalmars.com/d/statement.html#try. (I agree it'd be nice to have an actual example in the documentation using these keywords.)
