  I am developing an application using VB .NET 2003. The application need to read photo from a smart card using function from a dll. The photo is a JPEG data of size 4000bytes.
  
  First i declare the function that i need to use as:
  
  Declare Function Get_Picture Lib "smrtcrd.dll" Alias "_SC_Photo@4" (ByVal pbPhoto() As Byte) As Short
  
  This is the code snippet:
  
  Dim photo(4000) As Byte
  Dim i As Short = Get_Picture(photo)
  Dim fNum As Integer
  fNum = FreeFile()
  FileOpen(fNum, "C:\MyFile.gif", OpenMode.Binary, OpenAccess.ReadWrite)
  FilePutObject(fNum, photo)
  FileClose(fNum)
  PictureBox1.Dispose()
  PictureBox1.Image = Image.FromFile("C:\MyFile.gif")
  
  However, when the last line get executed, a 'System.OutOfMemoryException-Out of Memory' was thrown.
  
  Any idea why this happened? Please help!
