1. Data Structure Viz for VC++ debugger
OOL C By
Sumithra Luhui Shumei
Sam & Matt T

2. Motivation
Seeing Data flow during program execution. Vs

3. Strategy Get variables to be watched Get values at breakpoints
Categorize data variables as:
Heap & Stack Variables
Show relationships

4. Heap Variables Run-time variables tracked by VC++ debugger
Each node is a box with its fields
Nodes connected by pointers
Support flexible drag-drop
Right Click highlights pointer

5. Demo Time !

6. Stack Variables All watch variables in VC++ debugger
Display all these stack variables in a box
Includes all its basic information
Name, value, type & context
Enables quick finding and comparing of variables by name, data type & context using sorting
Enables identification of corresponding heap variables by click

7. Talking to the debugger!!!!!

8. Conclusions & Future Work
Better visualization of data structures, reflecting structure of tree, list etc.
Directed lines for pointers
Need feedback to support more fun
Future Work
Collect feedback from (all??) of you
Incorporate suggestions
Release ASAP
