OCR - refers to Optical Character Recognition
OMR refers to Optical Mark Recognition - the marking of multiple choice question.
I need some guidance on what technology to be used to develop the OMR ?
Should i use OCR technology from microsoft to try it ?
Thanks.

It really depends on the enviroment, but you are not looking to get characters from images. If I understand you right you are trying to figure out which answer is marked in a multiple choice question. You need a little mix of Image Processing/Computer Vision, but if it is laid out right it shouldn't be to hard.
Assumption: You are using some kind of image capturing device.

Take a look at the System.Security.Cryptography namespace.

I draw an image in the form_Paint event handler:
e.Graphics.DrawImageUnscaled(bmp,0,0/*panel1.Bounds*/);
But the image IS scaled! The size of bmp is 2048*1900, but the whole image was drawn in a small area of the form, the width was 800 more or less.
Why scaled? How can I make it unscaled?
|
|
|
|
|
That's really weird. Is there any sort of scaling transform happening on the graphics object ?

The DrawImageUnscaled method draws the image at it's original physical size. The size is about 11" wide, so it's resized to show up as 11" wide on the screen.
If you want to draw the image without resizing, use a different method.

Hi,
If there is a main form with various child forms that have context menus with generic items like copy and paste, how does it usually work in terms of merging these items? How do I make sure that the right 'copy' functionality is executed for each particular child form? Do I create these items in the main menu and then merge them with individual child context menus or vice versa?
thanx in advance

I need to update certain controls on a form in C# while a test sequence is performed that lasts up to 90 seconds while keeping a running record on that same form of the test results. Basically, the top half of the form will be the data entry portion of the form with the relevant text and combo boxes while the bottom portion of the form contains the data being tested. Certain labels and text boxes on the bottom part of the form need to be updated as the test progresses, but I need to enable the user to enter new data in the top half of the form. I thought perhaps multi-threading would solve the trick, but would the threads be able to access the same resource, this one form, at the same time?

Multi-threading *will* solve the problem. You just need to read a bit about synchronizing access to shared resources. There are many articles on the internet that cover this topic. Take a look at this article: http://www.c-sharpcorner.com/Code/2002/April/MultithreadingP3.asp[^] and then do a search for "C# thread synchronization".

Have you attempted debugging? Can you post code where the error message appears?
