Home work project 4: Selecting JPEG images by radio buttons

1. Description and coding requirements
2. How to submit

Description and coding requirements

• The purpose of this assignment is to practice loading multiple JPEG images and using the radio buttons to display one image at a time. The radio button widgets are described in Lab 12. The loading and displaying JPEG files, Fl_Image, and Fl_JPEG_Image classes are covered in Lab 6. You can use either project as a prototype, or start with a blank window (Lab 4) and follow the instructions in other handouts to implement the GUI interface and widget callbacks.

• Use hardcoded paths to the JPEG images (no need to use a file chooser to pick a file.) You should pre-load the images from files into memory as soon as the application starts. Display the images that correspond to the user selection:

   

   

How to submit

• Important: Before creating your ZIP archive:

  • Open your project in Visual Studio, click Build -> Clean Solution.

  • Important: Close your project in Visual Studio, File -> Close Solution and exit Visual Studio.

  • Open Windows File Explorer, click View -> check Hidden Items. You need to do this only once, this option is sticky.

  • Open your project directory in Windows File Explorer. There should be visible a hidden subdirectory named .vs.

    • The .vs directory in Microsoft Visual Studio is officially known as the Visual Studio solution "user options" directory. The .vs directory is automatically created in the same directory as your solution file (.sln) and contains all sorts of garbage for "improved performance" and "preserved developer preferences". It's size is huge and can easily exceed 30 Megabytes or more.

  • Important: Click .vs directory in Windows File Explorer and permanently delete .vs by clicking SHIFT Delete (press SHIFT and Delete keys simultaneously.)

  • In summary: Clean Solution is now complete and .vs directory is deleted.

  • Alternatively, you can run clean_before_submit.bat after exiting the Visual Studio. This will automate the clean-up instead of manual deletion. It's never a bad idea to run clean_before_submit.bat script before creating a ZIP arcive of the project.

• ZIP you entire project directory in a single ZIP file.

  • NOTE: Check the size of your ZIP file. If it's larger than 20-30 Kb, it's likely a sign of something wrong, like forgetting to remove the unwanted .vs subdirectory and so on.

• Log on to CIS-255 online , Weekly Assignments, and follow the appropriate upload link to submit your ZIP file.

  • Note: the system will display an 8-digit confirmation number once the file is successfully uploaded. You can save the confirmation number for your own records, but this is not a required step and no further action is needed on your part.
