Hi Igor and Alessio,
there are a bunch of image related controls that are shipped with Windows. There is one Image Admin Control which provides functions to administer image files including the manipulation of multi-page image files like TIFF (on my machine that is WangImage.AdminCtrl.1). Another control is the Image Scan Control (WangImage.ScanCtrl.1 on my machine) which handles scanning via TWAIN.
Since I started exploring these controls yesterday, I have no experiance how they are working with VFP. I found a knowledge base article Q161081 that tells about problems with the Scan Control under Win NT.
Maybe somebody around here can provide information concerning these controls.
I've acquired quite a taste for a well-made mistake... [Fiona Apple]
