I'm not sure that I understand your question. Why can't you hard-code the path?

Post this question in the article's forum (at the bottom of the page):

.NET TWAIN image scanner[^]

Pay more attention to what you're doing. There are plenty of notices that tell you want to do and how to do it on CodeProject.

Hi,

use the article :

.NET TWAIN image scanner[^]

and in the file GdiPlusLib.cs you can add the following method:

C#

public static bool SaveDIB(IntPtr bminfo, IntPtr pixdat )
{
  string FileName = "C:\\Test.bmp";
  Guid clsid;
  if (!GetCodecClsid(FileName, out clsid))
  {
    MessageBox.Show("Unknown picture format for extension " + Path.GetExtension(FileName), "Image Codec", MessageBoxButtons.OK, MessageBoxIcon.Information );
    return false;
  }
  IntPtr img = IntPtr.Zero;
  int st = GdipCreateBitmapFromGdiDib( bminfo, pixdat, ref img );
  if( (st != 0) || (img == IntPtr.Zero) )
    return false;
  st = GdipSaveImageToFile(img, FileName, ref clsid, IntPtr.Zero);
  GdipDisposeImage( img );
  return st == 0;
}

Calling this method will save the image to the hardcoded file C:\Test.bmp. You can modify this code to fit your needs.
