A problem for calling WINAPI CreateProcessWithLogonW~

[vcvycy]

/* Sorry For My Poor English =.=*/
 The code below can run successfully in vs2012。
But when I compiled it in Codeblocks, Codeblocks always reported an error:
      error: 'CreateProcessWithLogonW' was not declared in this scope|

 It puzzled me~
 #include<windows.h>
  BOOL bCreateProc =CreateProcessWithLogonW (
                      wcUserName,
                      NULL,
                      wcPassword,
                      0,
                      NULL,
                      wcCommandLine,
                      NORMAL_PRIORITY_CLASS,
                      NULL,
                      NULL,
                      &si,
                      &pi
                    );
   Then I maked a test:
   use LoadLibray("Advapi32.dll") and GetProcName("CreateProcessWithLogonW")to call this api.
   It Works!!!!!!!!!!!
   So Why this happend??
   Code Like This:
HMODULE hDll=LoadLibrary("Advapi32.dll");
  FARPROC p=GetProcAddress(hDll,"CreateProcessWithLogonW");
  printf("%x\n",p);
  BOOL WINAPI (*pfun)(
  _In_        LPCWSTR               lpUsername,
  _In_opt_    LPCWSTR               lpDomain,
  _In_        LPCWSTR               lpPassword,
  _In_        DWORD                 dwLogonFlags,
  _In_opt_    LPCWSTR               lpApplicationName,
  _Inout_opt_ LPWSTR                lpCommandLine,
  _In_        DWORD                 dwCreationFlags,
  _In_opt_    LPVOID                lpEnvironment,
  _In_opt_    LPCWSTR               lpCurrentDirectory,
  _In_        LPSTARTUPINFOW        lpStartupInfo,
  _Out_       LPPROCESS_INFORMATION lpProcessInfo
);
  pfun=(BOOL WINAPI (*)(
  _In_        LPCWSTR               lpUsername,
  _In_opt_    LPCWSTR               lpDomain,
  _In_        LPCWSTR               lpPassword,
  _In_        DWORD                 dwLogonFlags,
  _In_opt_    LPCWSTR               lpApplicationName,
  _Inout_opt_ LPWSTR                lpCommandLine,
  _In_        DWORD                 dwCreationFlags,
  _In_opt_    LPVOID                lpEnvironment,
  _In_opt_    LPCWSTR               lpCurrentDirectory,
  _In_        LPSTARTUPINFOW        lpStartupInfo,
  _Out_       LPPROCESS_INFORMATION lpProcessInfo
 ))p;

  STARTUPINFO si={sizeof(si)};
  wchar_t name[100]=L"352871242@qq.com";
  wchar_t pass[100]=L"pass";
  wchar_t cmd[100] =L"notepad";
  PROCESS_INFORMATION pi;
   BOOL bCreateProc =(*pfun) (
                      name,
                      NULL,
                      pass,
                      0,
                      NULL,
                      cmd,
                      NORMAL_PRIORITY_CLASS,
                      NULL,
                      NULL,
                      (LPSTARTUPINFOW)&si,
                      &pi
                    );

To compile an application that uses this function, define _WIN32_WINNT as 0x0500 or later.

AFAIK VS does it automatically, for CB use Project->Build Options->#defines

[vcvycy]

When I added "#define _WIN32_WINNT 0x0500" in "Build Options->Compiler settings->#defines",
It report
||=== Build: Debug in Test (compiler: GNU GCC Compiler) ===|
 _WIN32_WINNT||No such file or directory|
 0x0500||No such file or directory|
||=== Build failed: 2 error(s), 0 warning(s) (0 minute(s), 0 second(s)) ===|

When I added  "#define _WIN32_WINNT 0x0500" in main.cpp file,I seems nothing hanppend,still reported that function CreateProcessWithLogonW was not declared in the scope.

Do I did something wrong?

Yes, did it wrong.

From memory you need to add it like below; the CB defines are one per line.

Code

_WIN32_WINNT=0x0500

When I added  "#define _WIN32_WINNT 0x0500" in main.cpp file,I seems nothing hanppend,still reported that function CreateProcessWithLogonW was not declared in the scope.

You need to add the defines before any windows headers are included.

Edit: Fixed typos.

WOW!Problem Solved.
Just do as you say, Modify "#define _WIN32_WINNT 0x0500" to "_WIN32_WINNT=0x0500".
thanks!
When I want to use WinSock API ,I have to add "-lwsock32" in "Linker Settings",I perfer CB to VS because its convience.
But why there is so much constarin in windows development?
