How do I read a field to plot on a chart?

[User (Legacy)]

I'm trying to read data from a file that looks like this: 

"Date","Open","High","Low","Close" 

 8/03/1999,   62.50000,   62.56250,   60.25000,   61.12500 

 8/04/1999,   61.43750,   62.68750,   60.31250,   60.50000 

 8/05/1999,   61.12500,   61.56250,   58.37500,   61.50000 

 8/06/1999,   61.50000,   63.25000,   61.00000,   62.25000 

 8/07/1999,   62.31250,   63.56250,   60.31250,   61.03125 

 8/08/1999,   62.31250,   63.56250,   60.31250,   61.03125 

 8/09/1999,   63.12500,   63.87500,   59.62500,   59.81250 

And then use the following code to display it in a OHLC chart. What do I use 

as variables in place of "Open value!", and etc.? 

Dim CfxFile As New CfxDataFile 

    Dim nPoints As Integer 

    Dim j As Integer 

    CfxFile.FileName = App.Path & "\csco.csv"    ' data file 

    ChartFX1.GetExternalData CfxFile 

    nPoints = 7 

    ChartFX1.Gallery = OPENHILOWCLOSE 

    ChartFX1.OpenDataEx COD_VALUES, 4, nPoints ' Code to set the data 

    For j = 0 To nPoints - 1 

        ChartFX1.ValueEx(OHLC_LOW, j) = Open value! 

        ChartFX1.ValueEx(OHLC_OPEN, j) = Hi value! 

        ChartFX1.ValueEx(OHLC_CLOSE, j) = Low value! 

        ChartFX1.ValueEx(OHLC_HIGH, j) = Close value! 

    Next j 

   ' Close the VALUES channel 

    ChartFX1.CloseData COD_VALUES
