Question

我正在尝试使用Windows API和SetConsoleMode调用来更改Windows控制台模式，以用于输出（CONOUT$）。因此，我基于ConinMode.ps1（适用于 input ）对PowerShell脚本进行了修改。阅读在ConoutMode.exe和我的脚本中都可以正常工作，并返回：

# .\ConoutMode.exe
mode: 0x3
ENABLE_PROCESSED_OUTPUT            0x0001 ON
ENABLE_WRAP_AT_EOL_OUTPUT          0x0002 ON
ENABLE_VIRTUAL_TERMINAL_PROCESSING 0x0004 off   <====
DISABLE_NEWLINE_AUTO_RETURN        0x0008 off
ENABLE_LVB_GRID_WORLDWIDE          0x0010 off

# .\ConoutMode.ps1
OK! GetConsoleWindow handle  :  0x1F06D6
Console Input  Mode (CONIN)  :  0x21f
Console Output Mode (CONOUT) :  0x3

但是，我的脚本和exe都无法写入模式。（可能是因为它认为我的输出句柄未指向控制台？）

在PowerShell中：

# .\ConoutMode.exe set 0x000f
error: SetConsoleMode failed (is stdout a console?)

# .\ConoutMode.ps1 -Mode 7
OK! GetConsoleWindow handle  :  0x1F06D6
old (out) mode: 0x3
SetConsoleMode (out) failed (is stdout a console?)
At C:\cygwin64\home\emix\win_esc_test\ConoutMode.ps1:112 char:9
+         throw "SetConsoleMode (out) failed (is stdout a console?)"
+         ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo          : OperationStopped: (SetConsoleMode ...out a console?):String) [], RuntimeException
+ FullyQualifiedErrorId : SetConsoleMode (out) failed (is stdout a console?)

这是我的ConoutMode.ps1脚本的全部内容：

param (
    [int] $Mode
)

$signature = @'
[DllImport("kernel32.dll", SetLastError=true)]
public static extern IntPtr GetConsoleWindow();

[DllImport("kernel32.dll", SetLastError = true)]
public static extern IntPtr GetStdHandle(int nStdHandle);

[DllImport("kernel32.dll", SetLastError = true)]
public static extern uint GetConsoleMode(IntPtr hConsoleHandle, out uint lpMode);

[DllImport("kernel32.dll", SetLastError = true)]
public static extern uint SetConsoleMode(IntPtr hConsoleHandle, uint dwMode);

public const int STD_INPUT_HANDLE  = -10;
public const int STD_OUTPUT_HANDLE = -11;

public const int  ENABLE_PROCESSED_OUTPUT            = 0x0001;
public const int  ENABLE_WRAP_AT_EOL_OUTPUT          = 0x0002;
public const int  ENABLE_VIRTUAL_TERMINAL_PROCESSING = 0x0004;
public const int  DISABLE_NEWLINE_AUTO_RETURN        = 0x0008;
public const int  ENABLE_LVB_GRID_WORLDWIDE          = 0x0010;

$WinAPI = Add-Type -MemberDefinition $signature -Name WinAPI -Namespace ConoutMode -PassThru
#$WinAPI = Add-Type -MemberDefinition $signature -Name WinAPI -Namespace IdentifyConsoleWindow -PassThru

$hwnd = $WinAPI::GetConsoleWindow()
if ($hwnd -eq 0) {
    throw "Error: GetConsoleWindow returned NULL."
} 
echo "OK! GetConsoleWindow handle  :  0x$($hwnd.ToString("X"))"

function GetConIn {
    $ret = $WinAPI::GetStdHandle($WinAPI::STD_INPUT_HANDLE)
    if ($ret -eq -1) {
        throw "Error: cannot get stdin handle"
    }
    return $ret
}

function GetConOut {
    $ret = $WinAPI::GetStdHandle($WinAPI::STD_OUTPUT_HANDLE)
    if ($ret -eq -1) {
        throw "Error: cannot get stdout handle"
    }
    return $ret
}

function GetConInMode { #GetCOnsoleMode
    $conin = GetConIn
    $mode = 0
    $ret = $WinAPI::GetConsoleMode($conin, [ref]$mode)
    if ($ret -eq 0) {
        throw "GetConsoleMode (in) failed (is stdin a console?)"
    }
    return $mode
}

function GetConOutMode {
    $conout = GetConOut
    $mode   = 0
    $ret    = $WinAPI::GetConsoleMode($conout, [ref]$mode)
    if ($ret -eq 0) {
        throw "GetConsoleMode (out) failed (is stdout a console?)"
    }
    return $mode
}

function SetConInMode($mode) {
    $conin = GetConIn
    $ret = $WinAPI::SetConsoleMode($conin, $mode)
    if ($ret -eq 0) {
        throw "SetConsoleMode (in) failed (is stdin a console?)"
    }
}

function SetConOutMode($mode) {
    #$conout = GetConOut
    # Different tack:
    $conout = $hwnd
    $ret = $WinAPI::SetConsoleMode($conout, $mode)
    if ($ret -eq 0) {
        throw "SetConsoleMode (out) failed (is stdout a console?)"
    }
}

#----------------------------------------------------------
# MAIN
#----------------------------------------------------------
$oldInMode  = GetConInMode
$oldOutMode = GetConOutMode

$newMode = $oldOutMode
$doit = $false

if ($PSBoundParameters.ContainsKey("Mode")) {
    $newMode = $Mode
    $doit = $true
}

if ($doit) {
    echo "old (out) mode: 0x$($oldOutMode.ToString("x"))"
    SetConOutMode $newMode
    $newMode = GetConOutMode
    echo "new (out) mode: 0x$($newMode.ToString("x"))"
} else {
    echo "Console Input  Mode (CONIN)  :  0x$($oldInMode.ToString("x"))"
    echo "Console Output Mode (CONOUT) :  0x$($oldOutMode.ToString("x"))"
}

因此，最后，我想为控制台启用 ENABLE_VIRTUAL_TERMINAL_PROCESSING 。

我为此使用的系统是：

      Color Capability  : 23

      CodePage (input)  : 437
      CodePage (output) : 437

我还按照其他地方的说明启用了注册表项HKCU:\Console\VirtualTerminalLevel。

问：如何使用PowerShell启用此位/标志？

我能想到的某些事情可能是错误的：

我肯定对此有误的理解...
我可能写错了permissions来写到控制台吗？（如何设置？）
我可能不会写到correct输出缓冲区吗？（如何查找？）

请注意，设置一个屏幕缓冲区的输出模式不会影响其他屏幕缓冲区的输出模式。
执行脚本时，也许会创建一个新的输出缓冲区？（怎么办？）
我可能需要create a new缓冲吗？
我可能必须create a new控制台吗？

如何在Powershell中使用SetConsoleMode更改控制台输出模式？
