Program Codes is a program code download application (source codes). There are over 20 Windows applications in total. The codes are packed in a RAR file. After downloading, you need to unpack them and open the project in an IDE application. Project types are: C#, C++, Java. The codes only work in a Windows environment. The codes only need an IDE to compile and run programs after compilation. C# and C++ codes need Windows Visual Studio to compile. And Java codes Eclipse. The app is easy to use. To do this, press the Programs button in the main menu and you will see programs that you can download (Projects). Once you have selected an application, press the Open button. You can browse the application files and view them in the application tree. If you want to see the contents of the file, press the Content button, the file must be selected. You can see the contents of the files, not folders. If you want to download a Project, press the Download button. You can download the application if you have upgraded. This is a paid purchase. You can do this by pressing the Upgrade button in the Main menu. You can choose the location of the downloaded file on your device.
