Answer

Introduction

Visual Basic is a programming language that allows developers to create Windows applications. It provides a graphical user interface (GUI) and a wide range of tools and controls to build user-friendly and visually appealing applications. The challenge on page 370 of the textbook “Starting out With Visual Basic-7th Edition” focuses on file compression using a compressed (zipped) folder. This assignment requires implementing the solution in Visual Basic and delivering the final result as a compressed folder.

Overview of the Challenge

The challenge on page 370 involves writing a Visual Basic program to compress a folder and save it as a compressed (zipped) folder. The goal is to create a program that automates the compressing process, making it easier and more efficient for users to zip folders.

To begin, the program needs to prompt the user to select a folder to compress. This can be achieved using the OpenFileDialog control in Visual Basic, which allows users to browse and select a folder. Once the user selects a folder, the program needs to identify all the files and subfolders within the chosen folder.

Next, the program should create a compressed folder and save it to a specified destination. This can be done by utilizing the System.IO.Compression namespace in Visual Basic, which provides classes and methods for creating, opening, and manipulating Zip archives.

The program should then iterate through all the files and subfolders within the chosen folder and add them to the compressed folder. This process may involve recursively traversing the folder’s directory structure to ensure all files and subfolders are included.

Finally, the program should display a message indicating the success of the compression process, along with the chosen folder’s original size and the size of the compressed folder. This information can be obtained by querying the size properties of the folder and the compressed folder.

Approach and Implementation

To solve this challenge, you will need to use Visual Basic to write a program that incorporates the necessary steps outlined above. The program should have a user interface that allows users to select the folder they want to compress and specify the destination for the compressed folder.

Once the user selects a folder, the program should obtain a list of all files and subfolders within the chosen folder. This can be done using the Directory class from the System.IO namespace, which provides methods for working with directories in Visual Basic.

After obtaining the list of files and subfolders, the program should create a compressed folder using the System.IO.Compression namespace. The ZipFile class provides relevant methods for creating and working with zip archives. The program should use these methods to create the compressed folder and add the files and subfolders to it.

Upon successful creation of the compressed folder, the program should display a message with the necessary information about the folder’s original size and the size of the compressed folder. The FileInfo class from the System.IO namespace can be utilized to obtain file size information.

Conclusion

In conclusion, the challenge on page 370 of the textbook “Starting out With Visual Basic-7th Edition” involves creating a Visual Basic program to compress a folder and save it as a compressed (zipped) folder. The program should prompt the user to choose a folder, identify all files and subfolders within it, create a compressed folder, and add the files and subfolders to it. Finally, it should display information about the original size and compressed size of the folder. By utilizing the appropriate classes and methods in Visual Basic, this challenge can be effectively solved.
