The Daily Monitoring CMC project serves to monitor and manage daily activities efficiently. This document details the development process, including a log of encountered errors, their root causes, and the steps taken to resolve them.
- Initial Setup: Configured Visual Studio Solution for the Daily Monitoring CMC project.
- Project Configuration: Established project configurations for Debug and Release environments.
- Feature Development: Implemented core features following the requirements.
- Testing: Conducted unit and integration tests to ensure feature integrity.
Throughout the development, various errors were encountered. Below is a comprehensive inventory of these issues:
- Cause: Attempted to invoke a method on a null object reference within the service layer.
- Resolution Steps:
- Reviewed the stack trace to pinpoint where the NullReferenceException was thrown.
- Ensured all objects were properly instantiated before use.
- Added null checks as a preventive measure.
- Cause: The application was unable to establish a database connection within the predefined timeout period.
- Resolution Steps:
- Checked the database server status.
- Verified the connection strings in the application's configuration file.
- Increased the timeout value to accommodate longer connection times.
- Cause: Data binding issues in the user interface leading to incorrect or outdated data being shown.
- Resolution Steps:
- Analyzed the data-fetching and binding logic.
- Implemented
INotifyPropertyChanged
to update the UI in real-time when data changes. - Ensured synchronization between the data source and the UI.
- Cause: Incorrect handling of user credentials validation.
- Resolution Steps:
- Corrected the logic to compare the stored password hash with the entered password's hash.
- Added additional exception handling around the authentication process.
- Included meaningful error messages to help end-users understand the login failure reason.
- Cause: Report generation logic incorrectly aggregated data, leading to inaccurate results.
- Resolution Steps:
- Identified errors in the report query logic.
- Adjusted SQL queries to perform correct data aggregation.
- Validated the output against known data sets to ensure accuracy.
Note: The document will be updated continuously as new errors are discovered and resolved throughout the project lifecycle.
