To capture the output of the PowerShell command and store it in a string variable, you can modify the RunPowerShellCommandAsAdmin procedure to redirect the output of the PowerShell process and read it into a string. uses
Classes, Process, ShellAPI, SysUtils;
function RunPowerShellCommandAsAdmin(const ACommand: string): string;
var
ShellExecuteInfo: TShellExecuteInfo;
Output: TStringStream;
ProcessHandle: THandle;
BytesRead: DWORD;
Buffer: array[0..1023] of AnsiChar;
begin
Output := TStringStream.Create('');
try
FillChar(ShellExecuteInfo, SizeOf(ShellExecuteInfo), 0);
ShellExecuteInfo.cbSize := SizeOf(ShellExecuteInfo);
ShellExecuteInfo.lpVerb := 'runas'; // Requesting elevation
ShellExecuteInfo.lpFile := 'powershell.exe';
ShellExecuteInfo.lpParameters := PChar('-NoProfile -ExecutionPolicy Bypass -Command "' + ACommand + '"');
ShellExecuteInfo.nShow := SW_HIDE; // Hide the PowerShell window
ShellExecuteInfo.fMask := SEE_MASK_NOCLOSEPROCESS;
if not ShellExecuteEx(@ShellExecuteInfo) then
raise Exception.Create('Failed to execute PowerShell command as admin');
ProcessHandle := ShellExecuteInfo.hProcess;
repeat
if not ReadFile(ShellExecuteInfo.hProcess, Buffer, Length(Buffer), BytesRead, nil) then
Break;
Output.Write(Buffer, BytesRead);
until BytesRead = 0;
// Wait for the process to exit
WaitForSingleObject(ProcessHandle, INFINITE);
Result := Output.DataString;
finally
Output.Free;
CloseHandle(ProcessHandle);
end;
end;
// Usage
procedure TForm1.RunButtonClick(Sender: TObject);
var
Output: string;
begin
Output := RunPowerShellCommandAsAdmin('Your-PowerShell-Command-Here');
Memo1.Text := Output;
end;
In this modified code: - We create a TStringStream object named Output to store the output of the PowerShell command.
- After executing the PowerShell command with elevated privileges, we read the output of the process using the ReadFile function.
- The output is continuously read into the Output string stream until the end of the output is reached.
- We wait for the PowerShell process to exit using the WaitForSingleObject function to ensure that we capture the complete output.
- Finally, we return the content of the Output string stream as a string, which contains the output of the PowerShell command.
Now, when you call RunPowerShellCommandAsAdmin, it will execute the PowerShell command with elevated privileges and return the output as a string. You can then assign this output to your TMemo component or use it as needed in your Delphi application. Tags: Administrator PowerShell RunPowerShellCommandAsAdmin ShellAPI ShellExecute
