adyble	Posted - Dec 12 2025 : 11:00:33 Hello Edit - Just discovered something with the issue below - The demo is 32 bit, our app is 64 bit. Rebuilding your demo in 64 doesn't work either. Do you have a 64 bit Twin demo ? The issue - Using your Twain demo I can load my scanner into the combobox and get the number of scanners using this line - showmessage(IntToSTr(ImageEnView1.IO.TwainParams.SourceCount)); It returns 1 as expected. I've copied the ImageView amd combobox onto my form However when this is run - showmessage(IntToSTr(ImageEnView1.IO.TwainParams.SourceCount)); It returns 0. is there a setting I've missed somewhere? Thansk Andy

xequte	Posted - Dec 15 2025 : 03:29:58 Hi Andy Do you have any 64bit Twain drivers on your system, as 64bit applications cannot access 32bit drivers. Most scanners do not ship with 64bit Twain drivers, so you will probably need to use WIA. Nigel Xequte Software www.imageen.com
