- Basic Functionality
- Intersect Method returns Range Object representing intersection of multiple ranges
- Method fails when range doesn't intersect, returns Nothing
- Nothing keyword clears object variables to default value
- Practical Applications
- Used to check if changed cell is part of another range
- Works with Worksheet_Change Event to detect data changes
- Can handle non-contiguous ranges using different syntax
- Named ranges require existence check before intersection
- Error Handling
- On Error Resume Next stops errors when named ranges don't exist
- On Error GoTo 0 resets error trapping automatically
- Exit Sub stops Excel from processing errors
- Message box can be displayed instead of runtime error
