Acquire without Twain Driver dialog

[reynolds]

I want to be able to scan without displaying the Twain Driver dialog. I just want hitting the button to make it start scanning with no detours. Is there another function besides TwainAcquireToImageID that just does the scan?

Also, I need to know how to set the data source without having to display the Select Source dialog, as the TwainSelectSource method does.

Hi,

I want to be able to scan without displaying the Twain Driver dialog. I just want hitting the button to make it start scanning with no detours. Is there another function besides TwainAcquireToImageID that just does the scan?

You have just to call the TwainSetHideUI method like this:

Code: Select all

object.TwainSetHideUI(True)

Also, I need to know how to set the data source without having to display the Select Source dialog, as the TwainSelectSource method does.

You can list all the twain devices like that :

Code: Select all

For i = 1 To object.TwainGetSourceCount
       MsgBox object.TwainGetSourceName(i)
Next i

Then, you can open the desired device like that:

Code: Select all

object.TwainOpenSource ("Your source name")
