How can I get return code ans stdout of this code:

ShellExecute(null, "runas", "cmd", "/c netsh winhttp set proxy 
127.0.0.1:1234" , null, SW_HIDE);

Well, you can elevate your own program and tell it to run that 
command, collect the result and send it back through e.g. shared 
memory.

I don't want start with elevation, becouse program must be 
avaliable even user is not admin. Only ask for admin if normal 
usar ask for a command that need elevation.

Here is a hacky solution that attempts the command and fails back to 
asking the password. It should work on POSIX systems. (Tested on Linux.)

import std.stdio;
import std.process;
import std.format;
import std.algorithm;

// Copied the interface from executeShell
auto executeShellSudo(scope const(char)[] command,
                       const string[string] env = null,
                       Config config = Config.none,
                       size_t maxOutput = size_t.max,
                       scope const(char)[] workDir = null,
                       string shellPath = nativeShell) {
   // First assume the user is super user:
   auto suCommand = format!"sudo --non-interactive %s"(command);
   auto execute() {
     return executeShell(suCommand, env, config, maxOutput, workDir, 
shellPath);
   }

   auto result = execute();

   if ((result.status == 1) &&
       (result.output == "sudo: a password is required\n")) {

     // Have sudo ask for password. (Alternatively, sudo can be invoked
     // with the --askpass switch.)
     suCommand = format!"sudo %s"(command);
     result = execute();
   }

   return result;
}

void main() {
   auto result = executeShellSudo("cat /dev/null");
   writeln(result);
}

Can you put it into a small dub package?

I do not know how to do that. Observation: Remove the code 
.WaitForSingleObject (WAIT_TIMEOUT)

Use backticks instead of doublequotes, than you don't have to 
escape the doublequotes within the string. So:

alias runas = compose!(x => to!bool((cast(int) x) > 32), x => 
ShellExecute(null, "runas", "cmd", cast(wchar*)`/c "cd /d %s && 
%s"`.format(getcwd(), x).to!wstring, null, SW_HIDE);
