Question

Is it possible to set how many lines the console will print before it starts to erase the top ones? For example, is it possible to set it to 3 and only make the last 3 lines be visible? So:

std::cout<<"line 1!"<<std::endl;
std::cout<<"line 2!"<<std::endl;
std::cout<<"line 3!"<<std::endl;
std::cout<<"line 4!"<<std::endl;
system("pause");

Would output:

line 3!
line 4!
Press any key to continue...

^without creating a scroll bar on the side.

I’ve been trying to use Console::BufferHeight but I can’t seem to get it to work. This is the only thing I’ve been able to find that seems to be close to what I want to do: http://msdn.microsoft.com/en-us/library/system.console.bufferheight.aspx But It just shows how to read it, not how to set the size. And for some reason typing just std::cout<<System::Console::BufferHeight; gives me scope errors. Any help would be greatly appreciated. Thanks!

I think you want this:

• SetConsoleWindowInfo

Example,

HANDLE hConsole = GetStdHandle(STD_OUTPUT_HANDLE); 
SMALL_RECT rect = {0,0, 100, 100};
SetConsoleWindowInfo(hConsole, TRUE, &rect)

Have a look at these as well (experiment with them):

• SetConsoleScreenBufferSize()
• SetConsoleScreenBufferInfoEx

There is an example on MSDN here.
