About the Author

Shao Voon Wong
Software Developer (Senior)
Singapore Singapore
Shao Voon is from Singapore. His CodeProject contributions could range from being used in game changer Large Hadron Collider (LHC) of CERN to smash particles to something as frivolous as Maplestory game to as life changing as electrocardiography(ECG) project to everyday indispensable Irfanview image viewer.

CodeProject bestowed him a MVP award in recognition of his article contributions in 2019. In his spare time, he prefers to writing application based on 3rd party library than writing his own open source library. His interest lies primarily in computer graphics, software optimization, security and Agile methodologies.

One of these days, you can find him working on a DirectX based slideshow app called Mandy Frenzy.

You can reach him by sending a message on CodeProject or at his Coding Tidbit Blog!
