I am trying to develop a desktop application from which image can be scanned if scanner is connected with the pc and that will display in the picturebox control.

using WIA dll i am able to scan image from an external device(scanner) but it automatically saves default picture folder.
Can anyone please guide me how to save the picture as per my choice and display that image in a picturebox.

Thanks in advance.

Please have a look here,http://channel9.msdn.com/coding4fun/articles/Look-at-me-Windows-Image-Acquisition[^]

that pretty much sums it up

C#

tem item = device.ExecuteCommand(CommandID.wiaCommandTakePicture);
foreach (string format in item.Formats)
{
    if (format == jpegGuid)
    {
        WIA.ImageFile imagefile = item.Transfer(format) as WIA.ImageFile;
        filename = GetFreeFileName();
        if (string.IsNullOrEmpty(filename) == false)
        {
//Instead of saving  get it to the picture box (you should know how to convert it to Image object
            imagefile.SaveFile(filename);
        }
        this.picLastImage.Load(filename);
        return filename;
    }
}

private void button2_Click(object sender, EventArgs e)
{
    const string wiaFormatJPEG = "{B96B3CAE-0728-11D3-9D7B-0000F81EF32E}";
    CommonDialogClass wiaDiag = new CommonDialogClass();
    WIA.ImageFile wiaImage = null;

    wiaImage = wiaDiag.ShowAcquireImage(
            WiaDeviceType.UnspecifiedDeviceType,
            WiaImageIntent.GrayscaleIntent,
            WiaImageBias.MaximizeQuality,
            wiaFormatJPEG, true, true, false);

    WIA.Vector vector = wiaImage.FileData;

    Image i = Image.FromStream(new MemoryStream((byte[])vector.get_BinaryData()));
    i.Save(@"D:\prueba1.jpeg");
}

Final solution works perfectly.
