Cis 115 Final Programming Project Fall 2015 Smithdue Date 1155

Your organization has decided to conduct a fund raising effort to provide aid to local non-profit organizations this year. Each member has been challenged to raise funds by finding donors to sponsor them in one or more of the upcoming fund raising events (Holiday Run, Walk-A-Thon, Toy Drive). This program should include five events:

  • Enter Names: This event should be used to enter the member’s names into the input listbox. Use a sentinel value to indicate all students have been added, which should not be displayed in the listbox. After names are entered, determine the largest index, then ReDim the array to this size.
  • Make a Donation: Allow the user to select a member, choose an event, and enter an amount. Validate that all inputs are provided and the amount is positive and numeric. Display a unique message for each validation error, only one per execution. Each member’s total donation is stored in an array and updated with each donation.
  • Display Summary Information: Show current date, count of members with donations, count without, highest donation, lowest non-zero donation, and average donation (excluding zero balances).
  • Clear Event: Clears output listbox, donation textbox, selected event, and selected student name, but not the names listbox.
  • Exit: Closes the program.

Use modular programming with the specified functions/subs:

- DataOK()

- GetInput(amount, student, studentIndex)

- ProcessDonation(amount, studentIndex)

- DisplayOutput(amount, student, studentIndex)

- SetHighAndLow(high, low)

- Average(total, donationCount)

The donation totals array should be initialized to hold 20 values, then resized after name entry. Use appropriate control structures: If block, Do Loop, For Next Loop, when needed. Use loops to process array data without built-in functions for high, total, and average calculations. Follow good coding practices: meaningful variable names, proper passing parameters, clean formatting, and internal documentation.

Paper For Above instruction

The following comprehensive analysis and implementation of the fundraising program respond to the specified requirements, demonstrating proper modular programming, array handling, input validation, and user interface design in Visual Basic. This solution aims to facilitate efficient management of member donations, event tracking, and report generation to support a non-profit organization’s efforts.

Introduction

The objective of this project is to develop a user-friendly, reliable, and efficient Visual Basic application that enables a non-profit organization to record members’ donations across several fundraising events. The program should allow dynamic entry of member names, support donation processing with rigorous validation, generate comprehensive summaries, and manage interface controls systematically. Emphasizing modular programming and data validation, the system ensures accuracy, scalability, and ease of use.

Design and Implementation

1. Collecting Member Names

The initial step involves entering member names into a listbox. Using a sentinel value (e.g., "DONE") signals the completion of input. Names are stored in an array, which is dynamically resized to accommodate the actual number of entries. This ensures efficient memory use and flexible input handling.

2. Recording Donor Contributions

When processing donations, the program must verify that a member is selected, an event is chosen, and a valid donation amount is entered. Validation is critical here—if any input is invalid, an appropriate message is displayed, preventing erroneous data entry. A donation amount array tracks cumulative donations per member, updating with each new contribution.

3. Generating Summaries

On demand, the program computes and displays summary statistics: current date (retrieved via Date function), number of members with and without donations, highest and lowest donation amounts (excluding zeros), and average donation amount. Loops traverse the donation array to determine high, low, and total values, avoiding reliance on built-in functions and exemplifying core programming skills.

4. Clearing and Exiting

The clear event resets input fields and output displays without affecting the names listbox, maintaining member data. The exit event terminates the application gracefully.

Modular Programming

Each functional requirement is encapsulated into dedicated subs or functions:

  • DataOK(): Validates user input for donations.
  • GetInput(): Reads user selections and input, identifies the member index.
  • ProcessDonation(): Updates the donation array with the new amount.
  • DisplayOutput(): Shows confirmation of the donation made.
  • SetHighAndLow(): Finds maximum and minimum non-zero donations.
  • Average(): Calculates the mean donation ignoring zeros.

Array Management and Data Handling

The donation array is initialized to 20 elements, then resized after reading all member names to suit the number of members. All data processing involves careful looping constructs, with the avoidance of built-in functions for calculation as an exercise in fundamental programming techniques. Validation, resizing, and data updates adhere to best practices in dynamic array management.

Interface Design

The form includes controls for entering names, selecting members, choosing events (via combo box), entering donation amounts, and buttons for 'Make Donation', 'Display Summary', 'Clear', and 'Exit'. Proper naming conventions, tab order, and alignment ensure a professional appearance. An additional label displaying the programmer’s name enhances clarity. The interface design supports accessibility and operational efficiency.

Testing and Debugging

A comprehensive testing plan involves entering varied data sets, including edge cases (zero, negative, non-numeric donations), to verify validation logic. Loop-based calculations are validated for correctness against known values, ensuring accuracy. Debugging ensures no runtime errors and adherence to requirements.

Documentation and Finalization

The code includes internal comments describing purpose and functionality, beginning with a header comment with programmer details and purpose. Each event procedure contains a description of its role. Excess or unused code is cleaned before submission. The project is compressed into a zip file, named appropriately, and submitted electronically by the stipulated deadline.

Conclusion

This solution combines fundamental programming structures with sound design principles to create a functional fundraising management system. Its modular architecture promotes maintainability, and validation routines ensure data integrity. Such an approach not only fulfills the project requirements but also exemplifies best practices in software development using Visual Basic.
