Hi,
I do have experience of developing similar tool in Microsoft Excel with all features except dragging bars. Using same application logic, I can transfer my tool in .net with feature of dragging duration bar.
Following features were included in Excel version.
*Show chart in 3 formats (Day, Month and Quarterly)
*Manage Dependent tasks.
*Minimal Delay analysis.
*Manage proposed time and actual time.
*user friendly forms for operations like managing depndents and data entry.
I can show a snapshots of my Excel tool.
Thanks
