pointer to handle of a DIB??

[Bruce D]

I apologize...I'm new to VB .NET.
I'm wondering if I can somehow convert the pointer to the handle of a DIB to
the actual DIB? Below is the code that I use to get the pointer to the
handle of a DIB. The code works great!

Dim hdib As IntPtr
hdib = EZTwain.Acquire(Me.Handle())
If hdib.Equals(IntPtr.Zero) Then ....

Here's my problem...I'm trying to use this new property but it must be set
to a DIB...and apparently the hdib will not work. How can I get the DIB
from hdib?

Dim hdib As IntPtr
hdib = EZTwain.Acquire(Me.Handle())
PicssxBarcode1.hDIB = hdib ' this gives me an error because it's
expecting a DIB

I appreciate any help!

Hi,

There is a gdi+ function GdipCreateBitmapFromGdiDib that you can
call as an api call which I think will help. Maybe this will help.
