Generate QRcode in a picturebox

I'm trying to generate a QR code on a windows form and trying to set it to an image box. I got the following code from this source and the related files from here.

            private void GenerateQrcode(string _data, string _filename)
    {
        QRCode qrcode = new QRCode();
        qrcode.Data = _data;
        qrcode.DataMode = QRCodeDataMode.Byte;
        qrcode.UOM = UnitOfMeasure.PIXEL;
        qrcode.X = 3;
        qrcode.LeftMargin = 0;
        qrcode.RightMargin = 0;
        qrcode.TopMargin = 0;
        qrcode.BottomMargin = 0;
        qrcode.Resolution = 72;
        qrcode.Rotate = Rotate.Rotate0;
        qrcode.ImageFormat = ImageFormat.Gif;
        qrcode.drawBarcode(_filename);
    }

I want to know where this file is being created. What do I have to pass as file name, just a string as a name or the path of the directory which the file is being created. How can I display the created file in a picture box? like this?

       pictureBox1.Image = image;

The example on http://www.onbarcode.com/csharp/qr-code-generator.html says:

// Generate QR-Code and encode barcode to gif format
qrcode.ImageFormat = System.Drawing.Imaging.ImageFormat.Gif;
qrcode.drawBarcode("C:\\qrcode.gif"); 
/*
You can also call other drawing methods to generate barcodes          
public void drawBarcode(Graphics graphics);
public void drawBarcode(string filename);    
public Bitmap drawBarcode();
public void drawBarcode(Stream stream);             
*/
