c++ - CreateProcessAsUser fail，use GetLastError() to get the error code is 1314 -


i use win7 os , develop environment vs2005.

the situation want create process current account's priviledge.(such as: in normal account ,right click program choice "run admin" )

i refer other people's way: 1.get token of process explorer.exe; 2.improve priviledge; 3.use createprocessasuser create process.

but createprocessasuser failed,and use getlasterror() error code 1314.

because of that, think i'am crazy now. can tell me what's wrong in program. thank you!!!
