How to change BSTR in Visual Basic as VC++?

[C++ Programming]

Hi,

Private Sub Command1_Click(ByVal eventSender As System.Object, ByVal eventArgs As System.EventArgs) Handles Command1.Click

Dim barcord1 As String

barcordreader = New HANBARCORDLib.barcord

barcordreader.ReadBarcord("c:\image.raw")

barcordreader.GetBarcord1(barcord1)

Text1.Text = barcord1
End Sub
End Class

the variable, barcord1 is declared by "String".

And it is possible that a parameter of the method, "barcordreader.GetBarcord1(BSTR*)".
But I don't know how to change the code by Visual C++.

I actually made it like this :
BSTR barcord1[64]={NULL,};
barcordreader.GetBarcord1(barcord1);

but it doesn't work.
I want to get result as a type of string.
please help me.

Thanks for reading..
