Convert a small PS script into a long line in a .BATch file

Question

I have this PowerShell code that I got from the answer to this question; it show the location/dimensions of the cmd.exe window where the PS code run:

$Window         


        

Answer 1

I would go for the -EncodedCommand option here. You simply Base64 encode the entire powershell script and then pass the Base64 string as an argument to powershell.exe:

(assuming the script is here: C:\Path\To\Script.ps1)

PS C:\> $ScriptText  = Get-Content C:\Path\To\Script.ps1 -Raw
PS C:\> $ScriptBytes = [System.Text.Encoding]::Unicode.GetBytes($ScriptText)
PS C:\> $EncCommand  = [System.Convert]::ToBase64String($ScriptBytes)

$EncCommand now contains the Base64 encoded command, ready for use inside cmd.exe (or your batch file for that matter):

Double quote literals must be escaped as \"

There was a topic on DosTips a while ago that addressed this. You can make a batch/Powershell hybrid with a simple header:

<# :
:: Header to create Batch/PowerShell hybrid
@echo off
setlocal
set "POWERSHELL_BAT_ARGS=%*"
if defined POWERSHELL_BAT_ARGS set "POWERSHELL_BAT_ARGS=%POWERSHELL_BAT_ARGS:"=\"%"
endlocal & powershell -NoLogo -NoProfile -Command "$_ = $input; Invoke-Expression $( '$input = $_; $_ = \"\"; $args = @( &{ $args } %POWERSHELL_BAT_ARGS% );' + [String]::Join( [char]10, $( Get-Content \"%~f0\" ) ) )"

:: Any batch code that gets run after your PowerShell goes here
goto :EOF
#>

Just throw your Powershell code after the #> and save the file as a regular .bat script. In your case:

<# :
:: Header to create Batch/PowerShell hybrid
@echo off
setlocal
set "POWERSHELL_BAT_ARGS=%*"
if defined POWERSHELL_BAT_ARGS set "POWERSHELL_BAT_ARGS=%POWERSHELL_BAT_ARGS:"=\"%"
endlocal & powershell -NoLogo -NoProfile -Command "$_ = $input; Invoke-Expression $( '$input = $_; $_ = \"\"; $args = @( &{ $args } %POWERSHELL_BAT_ARGS% );' + [String]::Join( [char]10, $( Get-Content \"%~f0\" ) ) )"
goto :EOF
#>

$WindowFunction,$RectangleStruct = Add-Type -MemberDefinition @'
[DllImport("user32.dll", SetLastError = true)]
[return: MarshalAs(UnmanagedType.Bool)]
public static extern bool GetWindowRect(IntPtr hWnd, ref RECT lpRect);
[StructLayout(LayoutKind.Sequential)]
public struct RECT
{
    public int Left;
    public int Top;
    public int Right;
    public int Bottom;
}
'@ -Name "type$([guid]::NewGuid() -replace '-')" -PassThru

$MyWindowHandle = (Get-Process -Id (Get-WmiObject Win32_Process -Filter "ProcessId=$PID").ParentProcessId).MainWindowHandle

$WindowRect = New-Object -TypeName $RectangleStruct.FullName
$null = $WindowFunction::GetWindowRect($MyWindowHandle,[ref]$WindowRect)

Write-Host $WindowRect.Left $WindowRect.Top $WindowRect.Right $WindowRect.Bottom
