I had this problem with delphitwain – there was a bug with passing handle to virtual window (yes I mean DG_CONTROL, DAT_PARENT, MSG_OPENDSM). I needed to modify delphitwain source to fix this bug, but it helped (CreateWindow in procedure CreateVirtualWindow needs correct handle instead of 0). I don’t know EZTwain, so I just described my case 😉
Source dialog uses parent window handle passed to source manager, so you should make sure if you pass correct handle (probably there was mistake in getting handle) eg.
twain.loadSourceManager(GetActiveWindow());
srcIndex = twain.selectSource();- AuthorPosts
