Project management in Visual Studio

Common Bad Habit  Create a *.c / *.cpp file  Open it with Visual Studio  Compile

Bad Effect  NO Intelligent Sense  Class View / File View disabled  Can NOT debugging  Can NOT locate definitions An Expensive Notepad

What is Workspace & Project  Configuration files that help us managing the project  A workspace can have multiple project  Workspaces have the.dsw extension  Projects have the.dsp extension  Double click the workspace can auto launch the Developer studio

Other files used by devenv .ncb : Visual C++ IntelliSense Database .rc : Resource template .pch : Precompiled header .obj : Intermediate file .pdb : Program debugging database .bsc : Browse information .clw : Class wizard file (MFC only)

Using File View & Class View  File View : –Add new file –Delete file  Class View : –Locate functions & variables –Add new class –Add member functions and member variables

Project configuration  Debug version VS Release Version  Enable RTTI  Command line arguments

Useful Tips  Code auto formatting (Alt + F8)  Go to definition  Go to reference  Find in files  Open document

New features in VS.NET .dsw ->.sln  Integrated IDE  Measure up to C++ standard  ……

Develop Resource lookup

Microsoft Developer Network (MSDN)  All develop related resources  Online Version: – –Released every 4 months  Visual Studio 6.0 Version (.chm) –VB 6, VC 6, VFP 6, VJ 6, VID 6, Platform SDK  After Jan 2002, Visual Studio.NET Version –.NET framework

Demo : How to use MSDN

Other Resources  Knowledge Base –  TechNet –  Developer Works (IBM) –

Debugging with Visual Studio

What is debugging?  A process for identifying the root cause of a problem by tracing program execution flow and underneath memory status.  Beneficial after performing general troubleshooting steps.

Basic debugging knowledge  Symbols : The PDB files generated with your binaries by VS  Debugging tools –Visual Studio –Windbg / CDB ( For Windows ) –Debug ( For MS-DOS ) –Gdb ( For Linux / Unix / AIX )

Common Debug Scenario  Logic Error  Memory Leak  Access Violation (AV)

Basic Methodology  Set break point  Step into / Step over / Step out  Variables monitor (Local / Watch / Auto)  Call stack  Memory  Register  Disassembly

Demo : How to use Visual Studio.NET to debugging

Advanced Methodology  Conditional Breakpoint  Remote debugging (GDI / Kernel)  JIT debugging  Debugging running process  Debugging crash dump  Multithread debugging

Demo : Conditional Breakpoint Attach to a process

Solving Access Violation  Buffer Overflow / Underflow –Heap Corruption –Stack Corruption  Memory Access Denied –Raw Pointer –Double Free

The Hint  Debuggers are just tools  We must also : –Know the product –Know the languages and their implications (compiler implementation) –Know the operating system –Know the CPU –Know the tools

Introduction to Windows GUI Applications

What does GUI App Contains  Entry Point : WinMain  Register a window class  Create and Show a Window  Message Loops  Windows Procedure (WinProc)  Resource Template

Demo : Create and analyze a GUI application

Sample application of C++ project
