How can i get a multipage tiff (directly) in VB.net
I try something like that:

twain.SelectSourceByIndex(lstSources.SelectedIndex)

twain.OpenSource()
twain.IfTiffMultiPage = True
twain.IfShowUI = False
twain.EnableSource()

twain.AcquireImage()

Didn't works. What do I wrong?

Hi,

Here is a sample of multipage tiff for your reference:

Private Sub btnAcquire_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAcquire.Click
Twain.SelectSourceByIndex(lstSources.SelectedIndex)
Twain.OpenSource()
Twain.IfTiffMultiPage = True
Twain.IfShowUI = False
Twain.IfDisableSourceAfterAcquire = True
Twain.EnableSource()
End Sub

Private Sub Twain_OnPostTransfer(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Twain.OnPostTransfer
Twain.SaveAsTiff("c:\\twaintiff.tif")
End Sub

Hi Robert,

sorry but i have to ask again.

I do what you write. Scanner feeds now 2 piece of paper but the
tiff is empty.

Btw. my programm should show the pic. So I have a statement:
picImageAcquired.Image = twain.Picture instead of
twain.SaveAsTiff("twaintiff.tif")
Is this possible to?

But I try booth. With picImageAcquired.Image I see just the last page.

thx
Uwe
