I'd try this[^] and if that doesn't work for you then there's this[^]. Forgive me, both examples are in VB but converting them to C# shouldn't be too hard Smile | :)

Thanx man, it works like a charm Smile | :)

i am sooo sorry i never knew how things are done here,this is my first time of askin a question,i am not in the habi....I AM SO SORRY. i am actually workin on a desktop application..
and nobody will understand my code but i want to implement it in this area
its over 5000 lines of code, i thot nobody will be interested in that sh*t..
I AM VERY SORRY IF I HAVE OFFENDED ANYONE WITH MY APPROACH..

This is about as bad as code gets, plus you have not actually asked a question - you've just posted your crap repeatidly.

Stick to 419's!

Jamie is correct. This is some really nasty code and you haven't asked a question about it.

So, you're saying that you're writing code like this in an effort to build "job security" for yourself?? Thank God, 'cause I wouldn't want to be the poor bastard coming in behind you to support this code.

You didn't, and I apologise if you thought it was personal. There are some rules when posting in forums, and things can get a bit heated (read sarcastic) if these rules aren't adhered to. The first rule is that we don't do work for others. We'll help if they are stuck on a particular problem, but we won't write solutions. Secondly, we need decent descriptions of the problem - only then can we help. Third, we need to know that you've tried to solve the problem for yourself.

Tick all those boxes and you'll find your time on the boards a much more pleasant one.

Try to put some useful information in the subject line, so that it says anything about the question. That subject line contains no useful information at all.

Perhaps if you said anything at all about what the code is supposed to do...?

Oluwayomi wrote:
int TUT3, TUP3, COUT3;

Don't be afraid to use variable names that are somewhat longer. If you can see from the variable name what the variable is supposed to be used for, it's easier to understand the code, and easier to find errors.

Oluwayomi wrote:

An int is not an Int16, it's an Int32.

Why are you getting the value as a string, then convert it to a number? Do you store everything as text in the database?

Despite everything, the person most likely to be fooling you next is yourself.

Men...because im certified doesnt mean i knw the whole world...it might interest you to know that i have written my code..just needed ideas...WHY IS THIS A COMMUNITY?...ARE WE SUPPOSE TO HELP OR LAUGH AT?

Seriously though - you do know that we aren't here to write your code for you don't you? You didn't demonstrate that you had written a single line of code, and come on - this wasn't exactly a tough problem now was it? Hardly one that would tax a rocket scientist like yourself.

Fact is you posted not a question, but a vague demand. No please, no thank you, and the "problem" was poorly defined. Although anyway you look at the "problem", seriously, you don't know how to "triple" something? Be that performing elementary maths or repeating something three times.

Oluwayomi wrote:

So why not post your code and ask if anyone has a better suggestion? Then people would take your question seriously. I know myself I have sometimes written a piece of code and thought 'there must be a better way' but have had a mental block about how to do it better.

Oluwayomi,

We're all very sorry, come back!

What I'd like to be able to do is make a generic class for hardware status words where every bit in the word corresponds to a boolean named flag. I'd like to have something that would take advantage of the underlying type of the enum as well as some attributes that I'm tagging onto the enum. I thought I'd be able to do that, but I'm not having very much luck at it. I guess the enum is just being used as a template which is what I want. The question is, is it possible to take advantage of some of the enum features in a generic class?

Example target code:

enum AlarmTemplate : byte {
    [Description("High Liquid Level")]
    HighLevel,
    [Description("Low Liquid Level")]
    LowLevel
}
Byte theStatus = 0xA5;
StatusWord<<AlarmTemplate>> word = new StatusWord<<AlarmTemplate>>(theStatus); // where i can pass in the underlying type as an initializer
word.Bit[AlarmTemplate.HighLevel] = false; // Indexer
Byte temp = word.UnderlyingValue; // returns the enum's underlying type

I've always made custom classes to support all of these things, and lately I'm getting tired of it. Any ideas?

I don't know if I understood you correctly, but how about something like this

class StatusWord<T, U> where T : struct where U : struct
{
    U val;

    public StatusWord(U val)
    {
        this.val = val;
    }

    public bool this[T t]
    {
        set { val  = val | 0x001; }
    }

    public U Val
    {
        get { return val; }
    }
}

The code you show seems more or less OK (other than the doubled < and >), but I don't understand what you want to accomplish.

carbon_golem wrote:

Will the FlagsAttribute be of use?

I put the double <<>> to make the CP html generator show at least that it was generic. What I want to do is define named bits in a generic way. The named bits would be of standard lengths, 8, 16, 32, 64. I hoped to use an enum to provide a templating mechanism to do this, but so far no luck, and the solutions I have worked out aren't very type safe. What this is for is representing bit fields in embedded device logs. Here is my latest. A lot of it is shetchy, but...

public class StatusField<t>
        where T : struct {

        #region Members
        private T template;
        private ValueType sword;
        #endregion

        private StatusField(ValueType initialValue) {
            template = new T();
            if (template is Enum) {
                Type t = template.GetType();
                if (t.GetCustomAttributes(typeof(FlagsAttribute), false).Length == 0) {
                    throw new System.InvalidCastException("Requires Enum that defines FlagsAttribute");
                }
                sword = initialValue;
            } else {
                throw new System.InvalidCastException("Could  not convert generic type");
            }
        }

        public Object UnderlyingValue {
            get {
                return sword;
            }
            set {
                sword = (ValueType)value;
            }

        }

        public Boolean this[T index] {
            get {
                if (Enum.IsDefined(typeof(T), index)) {
                    Object x = Convert.ChangeType(index, typeof(Int64));
                    Int64 temp1 = (Int64)x;
                    Object y = Convert.ChangeType(sword, typeof(Int64));
                    Int64 temp2 = (Int64)y;
                    return (temp1 & temp2) == temp1;
                } else {
                    throw new IndexOutOfRangeException("Field is not defined");
                }
            }
            set {
                if (Enum.IsDefined(typeof(T), index)) {
                    // setter not defined
                } else {
                    throw new IndexOutOfRangeException("Field is not defined");
                }
            }
        }

        public static StatusField<t> New(ValueType value) {
            return new StatusField<t>(value);            
        }       
    }
</t></t></t>

And Usage:

            StatusField<alarms> field = StatusField<alarms>.New(Alarms.Battery | Alarms.Motion);
            Console.WriteLine(field.UnderlyingValue);
            Console.WriteLine(field[Alarms.Battery]);
            Console.ReadLine();
</alarms></alarms>

Thanks for the attention!

I suspect you need the FlagsAttribute, but I'm still unclear on what you are trying to do.

I would like to add some meta tags to a JPEG after it has been taken, unfortunately it is not possible to add the tags at the time the picture is taken. What I have found (best is here[^]) says it is not possible to add tags, so it is necessary to fool the JPEG by opening a current tag changing the values and than saving. While this work around does do the job it isn't very clean and seems like a problem waiting to happen. Does anyone know of a better way to add EXIF metadata after the picture has been taken?
Please let me know if it would be more appropriate to post this in the graphics form.
