Clearing a cmd screen with consolewrite()?

[TerarinK]

First your writing to the autoit screen and that is it, even if you execute it from the command line ConsoleWrite doesn't work that way.

ConsoleWrite doesn't work that way.

Yes it does, but you have to compile the script as a CUI (command line user-interface), right click 'compile with options'.

Here's a better way to clear the console (when running in cmd.exe that is)

Global Const $STD_OUTPUT_HANDLE = 2^32-11
Global Const $CONSOLE_SCREEN_BUFFER_INFO = "short dwSizeX;short dwSizeY;short dwCursorPositionX;short dwCursorPositionY;" & _
        "ushort wAttributes;short srWindowLeft;short srWindowTop;short srWindowRight;short srWindowBottom;" & _
        "short dwMaximumWindowSizeX;short dwMaximumWindowSizeY;"




Func _ClearConsole()

    $hConsole = DllCall("Kernel32.dll", "ptr", "GetStdHandle", "dword", $STD_OUTPUT_HANDLE)
    $hConsole = $hConsole[0]

    $csbi = DllStructCreate($CONSOLE_SCREEN_BUFFER_INFO)
    $call = DllCall("Kernel32.dll", "int", "GetConsoleScreenBufferInfo", "ptr", $hConsole, "ptr", DllStructGetPtr($csbi))


    $call = DllCall("Kernel32.dll", "int", "FillConsoleOutputCharacterW", "ptr", $hConsole, "short", 0, _
            "dword", DllStructGetData($csbi, "dwSizeX") * DllStructGetData($csbi, "dwSizeY"), "dword", 0, "dword*", 0)


    $call = DllCall("Kernel32.dll", "int", "CloseHandle", "ptr", $hConsole)

EndFunc  ;==>_ClearConsole

Have a look at post #15, you need to add a lot more lines to compete with Rover.

Oh, I totally missed Rover's post

But I still dont understand why my method works so well.

You would think that using the run command would start a NEW instance of cmd, not send commands to the currently open one. It just doesnt make sence.

It's very simple, you can even write cls.exe for yourself. What it does is attaching to the console of the parent process (which in this case is your script) and then use a method similar to Rover's and mine.

Ah I see. Thank you.
