ImagID = 0 ...

[Eric]

I have trouble...

The ImagID = 0 when i used the _oGdPictureImaging.TwainAcquireToGdPictureImage(Me.Handle) in HP Laser Jet 1536dnf MFP scanner.

Then i try other scanner that is Canon MG5300, and imageID <> 0.

I can't understand why no such condition occurs before when i used HP Laser Jet 1536dnf MFP scanner.

How do I solve this issue, thanks~
