Clearscreen

[teser]

How can I get the clear screen to work in my Visual C++ 6.0.

I tried the 'system("cls"' with no luck.

It works with 'clrscr();' in Borland but I need to get it to work in Visual C++.

Usually the system("cls&quot should work.
However, there is another , more complicated way of clearing the screen by using API functions from MSDN especially FillConsoleOutputCharacter

You have a sample of its usage in the following article from MSDN:
"HOWTO: Performing Clear Screen (CLS) in a Console Application"

The following code might look like overkill for just clearing the screen but it works...

int clear_console()
{

// Get the handle to Standard Output (STDOUT)

HANDLE hndlStdOut = GetStdHandle(STD_OUTPUT_HANDLE);
CONSOLE_SCREEN_BUFFER_INFO csBi;

// Fill console screen buffer
GetConsoleScreenBufferInfo(hndlStdOut, &csBi);
DWORD written;
DWORD SZ;

SZ = csBi.dwSize.X * csBi.dwCursorPosition.Y;
// csBi.dwCursorPosition.X + 1;
COORD curhome = {0, 0};

FillConsoleOutputCharacter(hndlStdOut, SPACE, SZ, curhome, &written);

csBi.srWindow.Bottom -= csBi.srWindow.Top;
csBi.srWindow.Top = 0;

SetConsoleWindowInfo(hndlStdOut, TRUE, &csBi.srWindow);
SetConsoleCursorPosition(hndlStdOut, curhome);

return 0;
}

And a slightly simpler way of doing it:

void clearScreen()
{
HANDLE hConsole = GetStdHandle(STD_OUTPUT_HANDLE);
for (int i = 0; i<50; i++) printf(&quot;\n&quot;
COORD pos0 = {0,0};
SetConsoleCursorPosition(hConsole,pos0);
}

Make sure you include the stdlib.h and system(&quot;cls&quot should work.

#inclide <stdlib.h>
