Hello Quan! That did the trick, many thanks!
By the way, I am using unsafe, because it is in the example Simple1.cs. Apart from that, I would rather not use it, since it propagates up.. and it doesn't prevent an application from crashing anyway. If you find the time, could you answer one more related question: I want to do screen text recognition, like text on menus, in notepad, and the like. Your testdata seems to be rather bad for this (now that it is running, I could test). How best to handle this? Create/get new testdata? Is it possible to use it without testdata at all? I would have expected screen recognition to be especially easy, since there is no noise. But then again, I have spent too little time to look into this yet.
