Why does my OpenGL Win32 app depth is limited and how to increase it?

Question

My OpenGL scene 3D becomes all black when it outs of the "3D viewport deepth" but i don't succeded to increase the value of the "camera depth far value"

Here is my whole code if you want to C/C in code blocks

I tried glDepthRange(0,100000); but unsuccessfull, my 3D cube became black if too far and I want to increase the value of "too far"
