Hi all,
I have Microsoft Visual C++.NET (Standard Edition) in my
Windows XP Home Edition PC.  I got a fatal error C1010:
unexpected end of file while looking for precompiled
header directive, when I tried to build the following
code of the Managed C++ Application in my PC:

/////////***Mixing1-Hello.cpp***//////////
#using <mscorlib.dll>
using namespace System;

#include "stdio.h"
void ManagedFunction()
{
        printf("Hello, I'm managed in this section\n");

#pragma unmanaged
UnmanagedFunction()
{
        printf("Hello, I am unmanaged through the wonder
of IJW!\n");
        ManagedFunction();
#pragma managed
int main()
{
        UnmanagedFunction();
        return 0;
//////////////////////////////////
Please help and advise me what is wrong with this set of
codes and how to correct the error.
Thanks in advance,
Scott  Chang
============================================
P.S.  The same fatal error C1010 occurred to the
following the mixing Managed C++ and Unmanaged C++
application too:

//////****Mixing2-Howdy.cpp****/////
#using <mscorlib.dll>
#include <vcclr.h>
using namespace System;

class CppClass {
public:
   gcroot<String*> str;   // can use str as if it were
String*
   CppClass() {}

int main() {
   CppClass c;
   c.str = new String(S"Howdy");
   Console::WriteLine( c.str ); // no cast required
/////////////////////////////////
Please tell me why the "Fatal Error C1010" happened to
both "Mixing1-Hello.cpp" and "Mixing2-Howdy.cpp".
Thanks again,
Scott  Chang

Greetings.

[Ordinary code cut.]

The compiler was told, via settings in your
project, to use a precompiled header in lieu
of compiling everything up to and including a
particular #include directive.  That directive
was not found, so the error you see was given.

Either turn off precompiled header usage for
those sources or put the appropriate #include
at the head of the file.  You can see what
that would be by examining compile settings
for that file.  Typically, (because it is
setup this way and not changed), this line:
  #include "stdafx.h"
is required.

You may want to consider putting #include's
used throughout your project into whatever
header is used precompiled.  This can speed
up your compilations quite a bit.

You're welcome.

Hi Larry, Thanks for your help and adsvice.

(1) I added #include "stdafx.h" to the Mixing1-Hello.cpp
program and built it in my PC - It worked perfactly.

(2) I added #include "stdafx.h" to the Mixing2-Howdy.cpp
program and built it in my PC (as Mix2-Hi.cpp) - I got 7
errors listed below:

------ Build started: Project: Mix2-Hi, Configuration:
Debug Win32 ------

Compiling...

Mix2-Hi - 7 error(s), 0 warning(s)

---------------------- Done ----------------------

    Build: 0 succeeded, 1 failed, 0 skipped
************************************************8
I do not know how to correct them - I am new in C++ and
Visual C++.NET programmings and I do not know how to put
the appropriate #include at the head of the file as you
instructed for the Minxing2-Howdy.cpp case. Please help me
again and tell me how to solve this new problem.
Thanks,
Scott  Chang

You may wont to put the #include "stdafx.h" statement on the first line in
the cpp file and not after the one with #using <mscorlib.dll>
e.g.

#include "stdafx.h"

#using <mscorlib.dll>
#include <vcclr.h>
using namespace System;

In this case the order makes a difference.
