About the Author

Ger Hayden

My first program was written in Basic on a Sinclair Spectrum ZX 16K in the summer of '85. Having studied Computer Systems I attempted to break into the world of C but took a wrong turn and got immersed in COBOL!

I looked a C again in 1994 but didnt follow up on it. In 2001 I introduced myself to Visual C++ 6.0 courtesy of Ivor Hortons book, but found the going difficult. I tipped my toe in the .NET water in '05 but the first example I tried in VC++ 2005 express didnt work and allied with the absence of MFC in the express package, I parked that up.

Along the way my career got shunted into software testing

A personal machine change force me to migrate to VS2008 in 2008. The new edition of Ivor Hortons book for VC++ in VS2008 reintroduced me to .NET and I got curious whereupon I went out and acquired Stephen Fraser's "Pro Visual C++/CLI and
the .NET 3.5 Platform". I am hooked!

After 20 years I think I have found my destination.
