[amibroker] Re: query from Vb.net->work around

["murthysuresh" <money@xxxxxxxxxxxxxx>]

Here is the workaround that i did

afl file
AddColumn(EMA(Close,9),"EMA");
Buy=1;
Sell=1;
Filter=True;

vb file.

 oAb = CreateObject("Broker.Application")
            oActiveDoc = oAb.activedocument
            txtSymbol.Text = oActiveDoc.Name
            oAA = oAB.Analysis
            oAA.applyTo = 1 'get the current symbol
            oAA.RangeN = 1  'get last day
            oAA.LoadFormula("C:\\Program 
Files\\AmiBroker\\Formulas\\Scans\\nineemascan.afl")
            oAA.explore()
            oAA.Export(sOutputFile)
            oRead = File.OpenText(sOutputFile)

            While oRead.EndOfStream <> True
                eachLine = oRead.ReadLine()
                eachLine = oRead.ReadLine() ' I am interestd in the 
second line only.

            End While

            oRead.Close()

            txt9Ema.Text = eachLine.ToString().Split(",")(2)



        Catch ex As Exception
            txtmessages.Text = ex.ToString()
        End Try
