#Sobolsoft screen scraping software
This is a pretty good option that gives a high level of accuracy for the screen scraping software but is also the most complicated (and therefore time and cost consuming) solution.

The so-called Mirror Drivers (starting from Windows 8 Accessibility drivers) are virtual device drivers that mirror all the drawing operations (including text drawing operations we are interested in) that happen on your screen onto a virtual screen.

The only disadvantage to this approach is that it uses some Windows undocumented APIs and with each security update it becomes harder and harder to do it. So when intercepting these methods, you can get all the text that is shown on the screen regardless of what UI framework is used, what font is used etc. Whatever UI framework the target application uses ( WPF, WinForms, QT or let’s say MFC) and whatever code one writes to add text label to some window – under the hood, in all of these cases, a very few common system functions are called (e.g., TextOut, DrawText, some GDI+ methods, etc.). The idea of this method is that the application will inject its code into all the running applications and intercept system API calls. This option is better than OCR because it can guarantee that you capture text from a desktop screen with 100% accuracy. Unfortunately, there are some applications like this out there. The reason for this is that OCR cannot guarantee 100% accuracy even with advanced training, which is not an acceptable solution if you are transferring sensitive information, e.g., accounting or medical information. OCR (Optical Character Recognition)Įven though we talked about this option first – in most cases, it is used only as a last (fallback) method if nothing else works. Luckily even if an application does not offer any good APIs for scraping screen data (mostly it is screen scraping software for capturing the text) there are still some options available. Unfortunately, transferring across isn’t always easily achieved if there aren’t existing APIs to support the transfer. This scenario means all the data will have to be shifted across to a new system. This is the easiest option as well as the most cost and time effective.
