Running in the Background PrintScreen App

C# Windows Form printscreen application that works in the background on Windows and saves the screenshot when the Print Screen key is pressed.

With the help of the Keyboard Hook class we can easily write the application. You will not notice this when the program runs. When you look at the directory C:\Windows\Science\ you can see screenshoot images. Every time you press the PrintScreen key, the new screenshot will be placed under this directory. You can change the file path in the open source code of the program.

Since the print screen program is hidden, nothing will appear on the screen when you build it with Visual Studio. For this reason, you can follow whether it works or not from the jpeg image files under the Science directory. Don’t forget to include the DLL files as a reference. The required DLL files are in the Debug directory.
