Answer 1

Check out http://www.pinvoke.net/ for signatures. Here’s a sime example.

 const UInt32 INFINITE = 0xFFFFFFFF;

 // Declare variables
 PROCESS_INFORMATION pi;
 STARTUPINFO si;
 System.IntPtr hToken;

 // Create structs
 SECURITY_ATTRIBUTES saThreadAttributes = new SECURITY_ATTRIBUTES();    

 // Now create the process as the user
 if (!CreateProcessAsUser(hToken, String.Empty, commandLine,
 null, saThreadAttributes, false, 0, IntPtr.Zero, 0, si, pi))
 {
 // Throw exception
 throw new Exception("Failed to CreateProcessAsUser");
 }

 WaitForSingleObject(pi.hProcess, (int)INFINITE);
