In Delphi, you can execute commands with administrator privileges by using the ShellExecute function with the 'runas' verb. However, if you want to execute a specific command with administrator privileges, you can use the CreateProcess function from the Windows API. Here's an example:
uses
ShellAPI, Windows, SysUtils;
function ExecuteCommandAsAdmin(const Command: string; var Output: string): Boolean;
var
StartupInfo: TStartupInfo;
ProcessInfo: TProcessInformation;
SecurityAttr: TSecurityAttributes;
StdOutPipeRead, StdOutPipeWrite: THandle;
StdOutReadTmp, StdOutRead: THandle;
WasOK: Boolean;
Buffer: array[0..255] of AnsiChar;
BytesRead: Cardinal;
begin
Result := False;
SecurityAttr.nLength := SizeOf(SecurityAttr);
SecurityAttr.bInheritHandle := True;
SecurityAttr.lpSecurityDescriptor := nil;
if CreatePipe(StdOutPipeRead, StdOutPipeWrite, @SecurityAttr, 0) then
begin
try
FillChar(StartupInfo, SizeOf(TStartupInfo), 0);
StartupInfo.cb := SizeOf(TStartupInfo);
StartupInfo.hStdOutput := StdOutPipeWrite;
StartupInfo.hStdError := StdOutPipeWrite;
StartupInfo.dwFlags := STARTF_USESTDHANDLES or STARTF_USESHOWWINDOW;
StartupInfo.wShowWindow := SW_HIDE;
WasOK := CreateProcess(nil, PChar('cmd.exe /C ' + Command), nil, nil, True, CREATE_NO_WINDOW or NORMAL_PRIORITY_CLASS, nil, nil, StartupInfo, ProcessInfo);
CloseHandle(StdOutPipeWrite);
if WasOK then
begin
try
Output := '';
repeat
WasOK := ReadFile(StdOutPipeRead, Buffer, 255, BytesRead, nil);
if BytesRead > 0 then
begin
Buffer[BytesRead] := #0;
Output := Output + string(Buffer);
end;
until not WasOK or (BytesRead = 0);
Result := True;
finally
CloseHandle(ProcessInfo.hProcess);
CloseHandle(ProcessInfo.hThread);
end;
end;
finally
CloseHandle(StdOutPipeRead);
end;
end;
end;
procedure TForm1.Button1Click(Sender: TObject);
var
Output: string;
begin
if ExecuteCommandAsAdmin('ipconfig /all', Output) then
ShowMessage(Output)
else
ShowMessage('Error executing command');
end;
Replace 'YourCommand.exe /parameter1 /parameter2' with the actual command you want to run and any necessary parameters. Please note that running commands with administrative privileges should be done carefully, and you should be aware of the potential security risks. Ensure that the command being executed is trustworthy and doesn't introduce security vulnerabilities. Tags: Administrator Privileges CreateProcess Delphi ShellExecute runas
