Twain Scanning in VB .Net
Hello,
I am trying to perform Twain scanning using the twain_32.dll, but no luck. Whatever solutions I have got call the dll GUI.
I want to perform scanning by passing custom settings to the scanner for every scan. For eg. In duplex I want to scan the Front side in color & Back side in Grayscale.
OR
Scan every Alternate page as Color and B/W
The combination can be anything. I've tried & and succeeded using WIA but it limited me to a certain extent.
Can anyone help me with how to proceed using TWAIN and without displaying the GUI.
I am open to options where a communication to Twain Connection Manager is established & commands are passed.
Thank you in advance

This pattern in common to all great programmers I know: they're not experts in something as much as experts in becoming experts in something.
The best programming advice I ever got was to spend my entire career becoming educable. And I suggest you do the same.

I'm assuming you're referring to yourself, since I see you edited your comment.

You lost me.
Wait, I see the moderator removed the post. The edit was because my math sucked, I said 12yrs.

That was me, my apologies for the confusion caused!
There was spam amongst the nonsense post, so I toasted it
