Hi,

I know exactly what you mean re the options available. Oddly enough it's the low level language capablities that I sometimes don't consider (e.g. operator overloading and implicit type conversions). Given:

    public struct YN
    {
        bool b;
        public static implicit operator string(YN x)
        {
            return x.b ? "Y" : "N";
        }
        public static implicit operator YN(string s)
        {
            YN x = new YN();
            x.b = s == "Y";
            return x;
        }
        public static implicit operator bool(YN x)
        {
            return x.b;
        }
        public static implicit operator YN(bool b)
        {
            YN x = new YN();
            x.b = b;
            return x;
        }
        public static implicit operator int(YN x)
        {
            return x.b ? 1 : 0;
        }
        public static implicit operator YN(int i)
        {
            YN x = new YN();
            x.b = i != 0;
            return x;
        }
    }

you could use some weird and wonderful syntax. E.g

            YN test = true;
            string s = test;
            if (test)
                textBox1.Text = test;

            YN test2 = "Y";
            bool b = test2;
            test2 = 0;
            s = test2;

But probably not a good idea!
Best,
Viv

>Thanks for the idea! I haven't looked at the format and parse event handlers in a while (I used them previously only to format decimals) so I totally neglected those as options. Those are now my 5th way of doing this :o) I'm playing around with it. I actually like this option better so far....

>I love the many options .net has, but I must admit, it gets frustrating at the same time that in .net, the options don't immediately come to mind yet. That may take a while. Of course, I used VFP since the early 80s so of course different ways of accomplishing would immediately come to my mind for it...

>>>I was overlooking the obvious that day. :o) The problem was with our default classes in the other layers. I had to create a special base textbox to control the saving. We have base classes but the base textbox classes already created only passed 'TRUE' and 'FALSE' based on a value of 'TRUE' or 'FALSE.' I had to create a new special basetextbox class to look for 'Y' and 'N,' but pass 'TRUE' or 'FALSE' to the business layer and then on to the other layers respectively...

Both of those work fine.
