MS Visual C++ not recognising headers

PHP Code:


		
			
// Time_Temp_Test.cpp : Defines the entry point for the console application.

//



#include <stdio.h>

#include <time.h>

#include "stdafx.h"



int _tmain(int argc, _TCHAR* argv[])

{

    time_t rawtime;

  struct tm * timeinfo;



  time ( &rawtime );

  timeinfo = localtime ( &rawtime );

  printf ( "Current local time and date: %s", asctime (timeinfo) );

  

  return 0;

}

Compiling...
Time_Temp_Test.cpp
Time_Temp_Test.cpp(13) : error C3861: 'time': identifier not found, even with argument-dependent lookup
Time_Temp_Test.cpp(14) : error C3861: 'localtime': identifier not found, even with argument-dependent lookup
Time_Temp_Test.cpp(15) : error C3861: 'asctime': identifier not found, even with argument-dependent lookup

Am F'd by the compiler failing to recognize the time and date functions. Is there something about MS Visual C++ which makes this difficult. I have the same code in other compilers and no probs. Any help appreciated.

try have the #include "stdafx.h" as the first line, I remember
having some issues when it wasn't first line.

Thanks shemzilla. Often wondered about that and will keep it first, but found problem which approaches a bug in the way the project dialog works.

The problem was Visual Studio was creating project files to use pre-compiled headers.

However, the version of XP I was using did not have the control time language for dot Net.

I think this resulted in the option to use pre-compiled headers, always being turn on, with the option to turn off, never appearing in the dialog box.

When I ran the project on an XP system with a full installation of dot Net, the problem became apparent.

I'm not familiar with all the options in MS VC++ and this was a real trap.
