C# = Retrieving yahoo historical prices

I follow most of this. I have a question about the

resultsGrid.DataSource = historicalData;

Do I need to initialize resultsGrid, or include a header or something to use that object?

I just dropped a DataGridView component from the toolbox on the form and gave it a name (resultsGrid). No initialization or headers required. The only code I added to the form is the code in my earlier post.

I did this in Visual C# community edition. My first piece of C# code ever...you've been warned.

Oh, the other bit of code was the OHLC class. Something like this:

Code:

class OHLC
    {
        private string date;
        private string open;
        private string high;
        private string low;
        private string close;

        public OHLC(string date, string open, string high, string low, string close)
        {
            this.date = date;
            this.open = open;
            this.high = high;
            this.low = low;
            this.close = close;
        }

        public string Date
        {
            get { return date; }
        }

        public string Open
        {
            get { return open; }
        }

        public string High
        {
            get { return high; }
        }

        public string Low
        {
            get { return low; }
        }

        public string Close
        {
            get { return close; }
        }

    }

Note: everything is a string. No datatype conversions etc. and no Volume property which you'd probably want to add.

If I knew I was going to get so many questions about this (PMs) I would have saved the code!

 

Mojo,

Big help, thanks a bunch. Good luck with your automation stuff by the way. I'm sort of "climbing that same ladder". Going to a lot of interviews in Chicago, looking for a entry position.


ANyway - first time with C#. Seems like you can do a lot of stuff like Vb.net. I'm going to read up on the diff. within in C++.

Thanks again
