Highlights yQ Qt Vs MFC y MySQL Vs Oracle y VC 6.0 Vs Visual C++ 2008

Qt Vs MFC Feature

Qt

MFC

O Overview i

G hi l C Graphical C++ ttoolkit lkit

Graphical G hi l toolkit t lkit for f Windows OS

Vendor

Initially, Trolltech. Now, Nokia

Microsoft

Year of Introduction 1994

Mid 90’s

Object Orientation

Clearly Object Oriented

Object oriented wrapper over Win32 API (Awful C/C++ Mix)

Platforms Supported

Windows, Unix flavors, Mac, Windows Embedded Devices

Design Model

Does not force any design model

Forces use of Document/View model and p Leads to templates. Difficulties.

Consistency

Consistent: naming, hierarchy, class organization

Lesser consistency, More tricks

Qt Vs MFC Feature

Qt

MFC

Communication C i ti Mechanism

Signal-Slot Si l Sl t callback llb k mechanism. Simple & Powerful.

Event-driven E td i fframework. k Not easy leading to problems sometimes.

Layout Mechanism

Supported

Not supported leading to problems when resized or translated

Designer Tools

Qt Designer. More powerful.

Resource Editor. Limited Capabilities.

Manual GUI Design

Easy and intuitive

Tedious

Documentation

Excellent. Just 18MB Excellent 18MB, integrated, and easy browsing & search.

MSDN Lib. Lib To be purchased, bulky, and search & browsing not easy

pp Unicode Support

Everyy string g is Q Qstring g (natively unicode). Conversions available.

To support pp unicode,, code changes are required. Problems due to DLL mismatches.

Qt Vs MFC Feature

Qt

MFC

I t Internationalization ti li ti

Justt single J i l method th d tr() t () takes t k Complex C l procedure d care. XML-based QtLinguist, involving string tables, supporting reusability also. LoadString(), conversions, updates, p , overlaps. p

Concept of Resources

No such concept. Only readable code.

Mostly, dependent on resources – can be edited using VS, Conflict problems

Cost

Free under GPL for Unix flavors and non-commerical Win apps. For commercial, Wi apps, costt iis $1 Win $1550. 0 Still worth investing it.

Visual Studio has free MFC SDK

Distribution

Names its DLL explicitly (qt- Can rely on Windows DLL mt404 dll)ÆSo no problems MFC42.dll mt404.dll)ÆSo MFC42 dll . If required to update then can cause problems to other programs.

Qt Vs MFC Feature

Qt

MFC

Mi ll Miscellaneous

Richer Ri h Widgets, Wid t XML support, Robust Templates classes, Memory Managements, g , N/W / API,, DB API, OpenGL API, Canvas, CSS

N/W API, API DB API, API STL exists but not as powerful as in Qt. No built-in XML parser,, memoryy p management.

Qt Vs MFC Conclusions Things can be done in both Qt & MFC but - Q Qt is technicallyy better - Memory, Speed, and Programmer efficient Qt is available with its own IDE: Q Q Qt Creater - Using 3rd party libraries may require tweaking Also,, available as Visual Studio plug-in p g - Tweaking not required for lib supported by VS but Qt used in limited way.

MySQL Vs Oracle Features

DB2 SQL Server MySQL

Oracle

Features

DB2 SQL Server

MySQL

Oracle

MySQL Vs Oracle Feature

MySQL

Oracle

Vendor

Initially, MySQL AB. Now, Oracle Inc.

Oracle Inc.

Open Source/ Proprietary

Open Source

Proprietary

System Requirements

Lesser compared to Oracle

More compared to MySQL

Limitations/Restrictions

Constrained by OS / HW

Oracle imposed constraints

Platform Supported

Multiple

Multiple

Languages Supported

Multiple

Multiple

Cost

Community Server: $0 no support. Enterprise Subs: $595+/server

$24000/ CPU including support & updates

MySQL Vs Oracle Conclusions - Oracle is industry player - MySQL y Q is technicallyy better - MySQL performance is comparable to Oracle - Used by y Google, g , Yahoo,, …. Growing g user base

Future of MySQL

Future of MySQL

VC++ 6.0 Vs Visual Studio 2008 Advantages of Visual Studio 2008 over Visual C++ 6.0: y Much more standards compliant C++ compiler compiler, with better template handling y Support for x64 / mobile / XBOX targets y Improved STL implementation y Support for C++0x TR1 (smart pointers, regular expressions, etc) y Secure C runtime library y Improved code navigation y Improved debugger; possibility to run remote debug sessions y Better compiler optimizations y Many bug fixes y Faster builds on multi-core/multi-CPU / systems y y Improved IDE user interface, with many nice features y Improved macro support in the IDE; DTE allows access to more IDE methods and variables y Updated MFC library (in VS2008 Service Pack 1)

VC++ 6.0 Vs Visual Studio 2008

Disadvantages of moving to Visual Studio 2008: y The IDE is a lot slower than VS6 y Intellisense still has performance issues (replacing it with VisualAssistX can help) y Side-by-side Sid b id assemblies bli make k app d deployment l t much h more problematic y The local (offline) MSDN library is extremely slow y Third-party tools support is fewer for Visual Studio 2008 e.g. there's no profiler in the Professional version
