Writing to file problem (Kernelbase exeption)

[Konrad via Digitalmars-d-learn]

Ok, I have rebuilded whole solution in MSVS (I'm using VisualD 
plugin) and everything started to work with my previously pasted 
code.

@Ali, thank you for advise with concatenation, I haven't thought 
about that.

Also thank you to all of you, guys, all that you wrote was very 
helpfull.

Best regards,
Ironus
