how can i resize window Console?

i did these code:

void SetWindowSize(COORD newsize)
    {
        PCONSOLE_SCREEN_BUFFER_INFOEX consolesize;
        GetConsoleScreenBufferInfoEx(hConsole,consolesize);

        COORD c;
        consolesize->srWindow.Right  = newsize.X+ consolesize->srWindow.Left;
        consolesize->srWindow.Bottom = newsize.Y+ consolesize->srWindow.Top;
        SetConsoleWindowInfo(hConsole, TRUE, &consolesize->srWindow);
        PCONSOLE_FONT_INFO consolefont;
        GetCurrentConsoleFont(hConsole, FALSE,consolefont);
        GetConsoleFontSize(hConsole,consolefont->nFont);
        c.X =(consolesize->srWindow.Right-consolesize->srWindow.Left)/consolefont->dwFontSize.X;
        c.Y =(consolesize->srWindow.Bottom-consolesize->srWindow.Top)/consolefont->dwFontSize.Y;
        DebugText("hello size " + to_string(c.X) + "  " + to_string(c.Y));
        SetConsoleScreenBufferSize( hConsole, c );
    }

but i get a memory leak, or i see the scrollbars.

what i'm doing wrong?

the SetConsoleWindowInfo() is give me a memory leak

but seems that depends on position

ok.. now no memory leak:

void SetWindowSize(COORD newsize)
    {
        CONSOLE_SCREEN_BUFFER_INFOEX consolesize;//see these type name
        consolesize.cbSize=sizeof(consolesize);//i forgot these
        GetConsoleScreenBufferInfoEx(hConsole,&consolesize);
        COORD c;
        consolesize.srWindow.Right  = newsize.X-1;
        consolesize.srWindow.Bottom = newsize.Y-1;
        CONSOLE_FONT_INFO consolefont={0} ;//see these type name
        GetCurrentConsoleFont(hConsole, FALSE,&consolefont);
        GetConsoleFontSize(hConsole,consolefont.nFont);
        c.X =(consolesize.srWindow.Right)/consolefont.dwFontSize.X;
        c.Y =(consolesize.srWindow.Bottom)/consolefont.dwFontSize.Y;
        SetConsoleScreenBufferSize( hConsole, c );
        SetConsoleWindowInfo(hConsole, FALSE, &consolesize.srWindow);
    }

i have 1 problem on c.X and c.Y calculations, because the vertical scrollbar continues visible :(

can you advice me?
