How to save a image using imagedata (C++ sample to vb.net)

I have a sample application written in C++ for a slap scanner. I am able to get the image scanned but do not know what to do with the data received. Can anybody guide me in the right direction?

I have attached the SaveImage Code from the sample app(Written in C++) and would like to know how convert it to vb.net. I am novice when it comes to C++.

I have tried to read the bytes from memory starting at the pointer returned to the tagImageData structure during the scanning process.

here is the structure that contains the image data:
    <StructLayout(LayoutKind.Sequential, CharSet:=CharSet.Unicode)> Public Structure tagImageData
        Public Buffer As IntPtr '< Pointer to image buffer
        Public Width As UInteger       '< Image horizontal size
        Public Height As UInteger      '< Image vertical size
        Public ResolutionX As Double  '< Horizontal image resolution (in PPI)
        Public ResolutionY As Double  '< Vertical image resolution (in PPI)
        Public FrameTime As Double    '< Image acquisition time (in seconds)
        '< This value contains the time taken for acquisition
        '< from device (excluding processing time).
        Public Pitch As Integer       '< Image line pitch (in Bytes).
        '  Positive values indicate top down line order,
        '  Negative values mean bottom up line order
        Public BitsPerPixel As Byte   '< Number of Bits per pixel
        Public Format As Integer      '< Image color format
        Public IsFinal As Boolean     '< Marks image as finally processed
        '  A value of "FALSE" disqualifies image for further processing.
        '  (e.g. interim or preprocessed result images)
    End Structure
