How to save and restore complete console state? I mean all data (position the appearance and the window size, content of the buffer etc.). So that after a close-down everything is like before the starting.

Hi CandyMan,

You have to gather all the available console information first.

GetConsoleScreenBufferInfo
GetConsoleCursorInfo
GetConsoleMode
GetConsoleCP
etc

Create your own active console (optionally).

CreateConsoleScreenBuffer
SetConsoleActiveScreenBuffer
SetConsoleMode
SetConsoleCP
etc

Restore the original console information on exit.

SetConsoleActiveScreenBuffer
SetConsoleTextAttribute
SetConsoleCursorInfo
SetConsoleWindowInfo
SetConsoleScreenBufferSize
SetConsoleMode
SetConsoleCP
etc

Hobby Basic does exactly that, it saves and restores complete console state.

Thanks for the help.
PS. After download and unpacking the Microsoft Security Essentials is detecting the Trojan Horse (Win32/Tiggre!plock) in the file "HB.EXE".

There are some false virus alerts but i'm trying to fix this problem. I think i'm on the right track.
