LOGON32_LOGON_NEW_CREDENTIALS - Undeclared Identifier Error

Posted on 2008-06-16
Last Modified: 2012-05-05
Using VS 6.0, LOGON32_LOGON_NEW_CREDENTIALS won't compile correctly. Anyone have any suggestions? This is a win32 windows service.

Code Snippet::

LogonUser(userName.c_str(),domain.c_str(),password.c_str(), LOGON32_LOGON_NEW_CREDENTIALS, LOGON32_PROVIDER_WINNT50, &userToken_);

Need a quick turn around on this if someone can figure out why this won't compile....

Hm, in your other Q, you mentioned you're using VC6 - you will need a new Platform SDK if you are using the files that shipped with VC6, since this constant was introduced years after VC6 was published. Get that update at ("Platform SDK")

I just updated the new platform SDK. I updated the tool-options -directories to update the include, lib and bin but the compiler still gives me the following:

error C2065: 'LOGON32_LOGON_NEW_CREDENTIALS' : undeclared identifier

Not sure if there is a specific dir in the new SDK install to point to.

That's very strange. Here, the SDK shipping with VC++ (aka VS2005) has
// Logon Support APIs
#define LOGON32_LOGON_NETWORK           3
#define LOGON32_LOGON_BATCH             4
#define LOGON32_LOGON_SERVICE           5
#define LOGON32_LOGON_UNLOCK            7
#if(_WIN32_WINNT >= 0x0500)
#endif // (_WIN32_WINNT >= 0x0500)
#define LOGON32_PROVIDER_WINNT35    1
#if(_WIN32_WINNT >= 0x0400)
#define LOGON32_PROVIDER_WINNT40    2
#endif /* _WIN32_WINNT >= 0x0400 */
#if(_WIN32_WINNT >= 0x0500)
#define LOGON32_PROVIDER_WINNT50    3
#endif // (_WIN32_WINNT >= 0x0500)

Open in new window

I went ahead and defined it in the stdafx.h and it worked.

#undef _WIN32_WINNT
#define _WIN32_WINNT 0x0500 // Required for LOGON32_LOGON_NEW_CREDENTIALS and LOGON32_PROVIDER_WINNT50 - W2k and above

Thanks for your assistance with this. You are very helpful and patience.
