Recognize a value from the desktop screen

Hello,

I have a question. I want to apply OCR(Optical Character Recognition) for a particular part of another software to get a data from it which is running in my desktop. Please suggest me how to get that? May be I should apply some other method in Matlab, if so please let me know how to do it? I have attached a picture of what i need to attain. The circled number(which is constantly changing) i need to have it as a value of a variable.

Regards,

J

Finally I got the solution,I am writing, so someone may find it helpful. I used a software called green screen grabber and program it to take a screen shot in specific area. Then I programmed in Matlab to run the software within the program. Once that was done i applied the OCR technique to read the image and get the number and perform my rest of the operation.

Thanks and regards, J
