Excel VBA Risk Assessment & Management 4

Question 1

In VBA-driven risk reporting, which event is most appropriate for automatically refreshing a risk summary table whenever the source data worksheet is activated?

Accepted Answer

Worksheet_Activate

Answer

Worksheet_Activate fires each time the user switches to that sheet, ensuring the risk summary reflects the latest data on every view.

Question 2

A risk analyst needs to run 10,000 simulation iterations in VBA without freezing Excel. Which technique best maintains UI responsiveness during the loop?

Accepted Answer

Call DoEvents periodically inside the loop

Answer

Calling DoEvents at intervals yields control to Windows temporarily, allowing Excel to process pending messages and appear responsive.

Question 3

Which VBA collection type is best suited for storing a dynamic list of unique risk identifiers where fast lookup by key is required?

Accepted Answer

Scripting.Dictionary

Answer

Scripting.Dictionary provides O(1) key-based lookup and enforces unique keys, making it ideal for mapping risk IDs to their records.

Question 4

A VBA procedure writes risk assessment results to a closed workbook using early binding to Excel.Application. What must be true for this to work reliably?

Accepted Answer

A reference to the Microsoft Excel Object Library must be set in the VBA project

Answer

Early binding requires a reference to the target type library so VBA can resolve object types at compile time, not just runtime.

Question 5

When a risk model macro needs to read configuration from a JSON file, which approach works in standard Excel VBA without third-party libraries?

Accepted Answer

Read the file as text and parse it manually with string functions

Answer

VBA has no native JSON parser, so reading the file as a text string and extracting values with InStr, Mid, or Split is the standard no-dependency approach.
