Just press F5 to continue running, or click the Debug Continue menu item to get to the error page. Let the program run.

It tells you the error type, the line in the code that is the approximate error location, and a stack trace to help in tracking down how that line of code was reached. You can replace this detailed error page with a custom error page and can control who gets to see what by setting the mode attribute of the CustomErrors element in the configuration file, as will be described next. how to implement ocr in c# Tesseract OCR simple example - Stack Overflow
