resolved:
Code:
//clear the Console
void Clear()
{
// home for the cursor
COORD coordScreen = {0, 0};
DWORD cCharsWritten;
CONSOLE_SCREEN_BUFFER_INFO csbi;
DWORD dwConSize;
// Get the number of character cells in the current buffer
if(!GetConsoleScreenBufferInfo(GetStdHandle(STD_OUTPUT_HANDLE), &csbi))
return;
dwConSize = csbi.dwSize.X * csbi.dwSize.Y;
// Fill the entire screen with blanks
if(!FillConsoleOutputCharacter(GetStdHandle(STD_OUTPUT_HANDLE), (WCHAR)' ', dwConSize, coordScreen, &cCharsWritten))
return;
// Get the current text attribute.
if(!GetConsoleScreenBufferInfo(GetStdHandle(STD_OUTPUT_HANDLE), &csbi))
return;
// Set the buffer's attributes accordingly.
if(!FillConsoleOutputAttribute(GetStdHandle(STD_OUTPUT_HANDLE), csbi.wAttributes, dwConSize, coordScreen, &cCharsWritten))
return;
// Put the cursor at its home coordinates.
SetConsoleCursorPosition(GetStdHandle(STD_OUTPUT_HANDLE), coordScreen);
}
thanks for all
