How to Embed an exe Inside Another exe as a Resource and Then Launch It

While working on a utility project today, I stumbled upon wanting to embed an executable inside another executable. Sounds fun doesn’t it? And what is even more fun is to be able to launch the embedded exe!

Basically, here’s how it works. You embed Foo.exe inside Bar.exe. And by embed I mean, add Foo.exe as a resource in Bar.exe and then, from Bar.exe’s code, you can launch Foo.exe using CreateProcess().

So before answering the "Why?" lets answer the "How?"

Latency numbers every programmer should know

L1 cache reference ......................... 0.5 ns
Branch mispredict ............................ 5 ns
L2 cache reference ........................... 7 ns
Mutex lock/unlock ........................... 25 ns
Main memory reference ...................... 100 ns             
Compress 1K bytes with Zippy ............. 3,000 ns  =   3 µs
Send 2K bytes over 1 Gbps network ....... 20,000 ns  =  20 µs
SSD random read ........................ 150,000 ns  = 150 µs

Read 1 MB sequentially from memory ..... 250,000 ns = 250 µs
