Debugging a BarsType help

April 18th, 2011, 09:18 PM

I've been unable to get Studio 2008 to debug a BarsType. And, of course Print() does not work in that class. Can someone point me in the right direction? I'm somewhat a novice in C# & VS 2008. Thanks for any help.

Could you throw us a few lines of code to show what you are trying to do? You should be able to access that in OnStartUp() if you are looking to Print it.

Code

Print(DateTime.Now + " Instrument and Bars Type " + Instrument.FullName + " " + BarsPeriod.Value + " " + BarsPeriod.Id);

Try that in OnStartUp(). Is that what you are trying to do?

... BarsType. And, of course Print() does not work in that class.

And, there is no OnStartUp() in a BarsType class.

Thanks for trying MXASJ.

BarsType has a ToString() method. But again I don't understand what you are trying to do...

One way is to use StreamWriter to create a file that will write what you want to a text file.
Bar Types don't do PRINT statements. (as far as I know)

Something like this maybe:

Code

// at the beginning
System.IO.StreamWriter file = new System.IO.StreamWriter("c:\\BarTextFile.txt");
...
// every time you want to make a note of something
file.WriteLine("Hello World");
file.Flush();
...
// when done
file.Close();

You can download a sample that NT provides if you have issues.

Thanks David. StreamWriter starts to work, but then I get the same kind of error regardless if I use NT's sample, code or yours, or the examples on Microsoft's web site How to: Open and Append to a Log File

Shortly after the file is created and written to I get this error in the trace log

I've gotten the best results using this

Code

 
private string        path                = Cbi.Core.UserDataDir.ToString()+"LBWickedTest "+DateTime.Now.ToString("_yyyy.MM.dd")+".txt";
private System.IO.StreamWriter            sw;

public override void Add(Bars bars, double open, double high, double low, double close, DateTime time, long volume, bool isRealtime)
        {
            sw = File.AppendText(path);
                        int barcnt = bars.Count;
            sw.WriteLine("{0} :  Barcnt = {1}",time, barcnt);
            ....
            ....
            sw.Flush(); sw.Close();    // CLEAN UP
        }
// Bar logic code End ----------------------------------------------------------------------------

I would appreciate any other suggestion.

I got things working, and will post a Wiki later after I'm done debugging. Thanks David for pointing me in the right direction.
