My assumption here is that you're trying to add -auto to the arguments. After reviewing the supplied image I would change the PowerShell code as well.
$task = Get-ScheduledTask "Test"
$items = #{}
if ($task.Actions.Execute -ne $null) {$items.Add('Execute', "$($task.Actions.Execute)")}
$items.Add('Argument', "$($task.Actions.Arguments) -auto")
if ($task.Actions.WorkingDirectory -ne $null) {$items.Add('WorkingDirectory',"$($task.Actions.WorkingDirectory)")}
$action = New-ScheduledTaskAction #items
$task.Actions = $action
Set-ScheduledTask -InputObject $task
Far simpler and easier to understand.
To run this in c++ you should dump the code to a temporary file.
#include <iostream>
#include <fstream>
using namespace std;
int main()
{
ofstream file;
file.open("test.ps1");
string newArg = "-auto";
string powershell;
powershell = "$task = Get-ScheduledTask \"Test\"\n";
powershell += "$items = #{}\n";
powershell += "if ($task.Actions.Execute -ne $null) {$items.Add('Execute', \"$($task.Actions.Execute)\")} \n";
powershell += "$items.Add('Argument', \"$($task.Actions.Arguments) " + newArg + "\") \n"; // 'Argument' not a typo
powershell += "if ($task.Actions.WorkingDirectory -ne $null) {$items.Add('WorkingDirectory',\"$($task.Actions.WorkingDirectory)\")} \n";
powershell += "$action = New-ScheduledTaskAction #items\n";
powershell += "$task.Actions = $action\n";
powershell += "Set-ScheduledTask -InputObject $task\n";
file << powershell << endl;
file.close();
system("powershell -ExecutionPolicy Bypass -F test.ps1");
remove("test.ps1");
}
