VC2005 cannot build project, complains about missing items...

I am trying to compile a code example from a hardware protection key
supplier.
The example should compile but does not on my VS2005 installation.
I suspect that I have not done something I need to do inside the
VS2005 IDE, but being a complete novice in C++ and Visual Studio 2005
I don't know what it can be....

The first problem was that it stopped on this include line:
#include <istream.h>
saying the file could not be found.

After looking in the VC/include dir below VS2005 I found a file called
istream (no extension), which seemed to be a header file so I renamed
it to istream.h.

Next I received no less than 10 errors (lines wrapped due to
newsreader):

1>c:\engineering\projects\bosse\safenet\spquery\dsdll.h(72) : error
C4430: missing type specifier - int assumed. Note: C++ does not

If I doubleclick the first error I get to this piece of code:

extern __declspec(dllexport) WINAPI SAFEInitGlobal(unsigned char*);
typedef (WINAPI *TSafeInitGlobalFnPtr)(unsigned char*);


extern __declspec(dllexport) WINAPI DecodeKeyID(
unsigned char*,
char*,
RESULTREC*,
unsigned short*);
typedef (WINAPI *TDecodeKeyIDFnPtr)(unsigned
char*,char*,RESULTREC*,unsigned short*);

extern __declspec(dllexport) WINAPI GenerateUpdateStr(
unsigned char *GlobPtr,
SAFECOMMANDREC *safe_commands,
short count,
char *updateStr,
PROD_LIST *prod_list_ptr,
BOOL ScrambleOrder);

As far as I can see there are no unspecified types anywhere here, so
what is the problem????

Now I am at road's end, I have not a single clue as to why the errors
happen. Apparently this compiles fine in an earlier version of VS
(when I load the project it says it has to convert to the new format
and I cannot go back to the old environment afterwards).

Any help appreciated!
(Bear in mind that I am not used to working with VS2005, I have only
worked with VB6 (a lot) and Borland products....

It seems that the example is for VC++6.0. Nowadays "xxx.h"
stream headers are deprecated and not used anymore. Streams
are part of Standard C++ Library and should be included as
any other facility:

#include <istream>

It's bad idea to rename library's header file, since other
components may include it, too.

Most likely you get this error due to `WINAPI' token. Ensure
that you have Platform SDK properly installed and integrated
with Visual C++. If you use Express edition of VS, then read
here for additional info:

"Using Visual C++ 2005 Express Edition with the Microsoft
Platform SDK"
http://msdn.microsoft.com/vstudio/express/visualc/usingpsdk/

Also, don't forget to include <windows.h>. However, it
should be arranged for you by IDE's wizard anyway.

I assume that you have installed protection key SDK and made
it available for the project.

Speaking about compilation and linking, Borland's products
based on same basic principles. You need header files in
order to compile and lib/obj files in order to link. All you
need to do is to specify relevant directories in IDE where
compiler/linker can find required files.

Right, I happened to have VC++6 installed as well so I loaded the
example into that and sure enough it built OK.

What i did was to copy all files without extensions to a new dir and
in tha I added the .h extension. Then I set VS2005 to look into this
dir as the last one on the list..

I have the full MSDN edition (been an MSDN member for 12 years now).
Using this I have been abvle to build other applications (open-source
apps) without these problems. But the open source projects probably
have a more careful file layout with defines to cure problems arising
from various VS versions..

Bo/Alex:

VC6 would accept the new iostream library (or the old one, provided you
did not mix them). So this is not an issue of "the example is for VC6",
but rather "this code is obsolete, and should not compile".

Ask the supplier for a corrected version of the code. It is very easy to
write code that will compile on both VC6 and VC8.
