I want to add TWAIN scan feature to image viewer control.
It will add selectsource method, it will display DS Source dialog, if you installed more than one twain source, you can select it.
showtwainUI property , true display twain UI, false not display.
FeederEnabled property, true enabled the feeder, false disable the feeder.
scan() method, it will scan the image from selected twain source and display the image on image viewer user control and image thumbnail list. If I call scan again, it will display next page. In image thumbnail list will have 2 image.
Finally create sample show me how to use this image viewer user control and calling these feature.
If you use third party dll or open source , you need send the source code to me, all source code need compiled.
and you need show me how to distribute this dll to client computer automatically.
e.g. how to add dll to .xap file and installed on client computer automatically.
