问题 I am using a COM object (MODI) from within my .net application. The method I am calling throws a System.AccessViolationException, which is intercepted by Visual Studio. The odd thing is that I have wrapped my call in a try catch, which has handlers for AccessViolationException, COMException and everything else, but when Visual Studio (2010) intercepts the AccessViolationException, the debugger breaks on the method call (doc.OCR), and if I step through, it continues to the next line instead of

问题 I have a form where the user can first scan to a bitmap. When scan is done, and the bitmap is loaded, I have 4 text boxes that are then enabled. Next to each text box, I have a button called "Cut from image". When the user clicks the button, they can click and drag in the bitmap to get the selected text using MODI. This works perfect except for one annoying bug: When I click a "Cut from image" button and drag a square, it gets the information nicely to the text box. Then, if i click to the

问题 I have been reviewing replacements for the Office 2007 MODI OCR (OneNote's 2010 solution has lesser quality/results than 2007 :-( ).

问题 I'm trying to use MODI to perfom OCR on bitmaps I already have in memory. I can't seem to find a solution to this as all the examples I find use the create method to grab the image from the disk and prepares it for the OCR., however, I already have the image on memory and writing and reading i to and from the disk consumes too much time. Bitmap bmp = ... //Instantiate the MODI.Document object MODI.Document md = new MODI.Document(); //The Create method grabs the picture from disk snd prepares
