CreateProcess to launch command prompt

[Imtiaz Murtaza]

Friends, I want to launch command prompt window from my application running on Windows Vista. For this purpose i am using CreateProcess. What i want is that command prompt window shoul be launched with Administrative priviliges. Please tell me how can i do so ?

I'm not sure about CreateProcess(). But maybe this:

::ShellExecute(NULL, _T("runas"), _T("c:\\Windows\\System32\\cmd.exe"), _T(""), _T(""), SW_SHOWNORMAL);

Not counting the run as administrator part, I'd do it like this:

// Win32.cpp : Defines the entry point for the application.
//

#include "stdafx.h"
#include <windows.h>
#include <tchar.h>
#include <shellapi.h>
#include <malloc.h>
#pragma comment(lib, "shell32.lib")
 
int APIENTRY WinMain(HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPSTR lpCmdLine,
int nCmdShow)
{
DWORD size = GetEnvironmentVariable(_T("ComSpec"), NULL, 0);
LPTSTR pPath = static_cast<LPTSTR>(_alloca(size*sizeof(TCHAR)));
GetEnvironmentVariable(_T("ComSpec"), pPath, size);
 
ShellExecute(NULL, NULL, pPath, NULL, NULL, SW_SHOWNORMAL);

return 0;

}

This code makes no assumptions about the location of the windows folder or the location and name of the command interpreter.

Sweet!  Thanks for that!! Just add the runas verb and it will prompt for elevation...

ShellExecute(NULL, _T("runas"), pPath, NULL, NULL, SW_SHOWNORMAL);

Filed for future reference, thanks! Mark

have a look at CreateProcessWithLogon, CreateProcessWithToken, CreateProcessAsUser.
