I've had this before and was never able to narrow down the exact cause, but
is seemed to have to do with the order of #using<> statements (esp. when
you're including header files that also have #using<> statements). Make
sure you're not #using anything twice if you don't need to or at all if you
don't need it.

Thanks for the clues Brian but no joy. I have stripped
things down so that I have four files.
OrderEnumerator .h
OrderEnumerator .cpp
OrderCollection .h
OrderCollection .cpp
These files are not included in any other project files.
Adding #include "OrderEnumerato r.h" to OrderCollection .cpp
causes the error in question. I don't actually use
anything from OrderEnumerator .h I just include the file.
There are no #using statements in these files. I include
the definitions of the itga:: stuff via stdafx.h, I have
tried including them directly in both the header and cpp
files in question as well.
Furthermore if I comment out the use of
itga::order_col lection::iterat or then the problem goes
away. Everything compiles fine and I use the
itga::order_col lection::iterat or elsewhere (in a plain cpp
library and a COM wrapper library) with no problems both
with VC++ and G++ on solaris.
All the unerlying cpp files have include guards and the
managed header files all have #pragma once.
It appears VC++ is generating some kind of symbol
information and getting it wrong, maybe involving forward
declarations?
btw, I'm using visual studio 2003.

Hi Daniel,
No luck still, the two files in question
OrderCollection .cpp and OrderEnumerator .cpp have exactly
the same build options. They each include the unmanaged
code through a single header which is included in stdafx.h.
I used metainfo to dump the .obj files and I can't see any
differences in the type in question
itga::order_col lection::iterat or, although I am admittedly
inexperienced with this and could be missing something.
I had initially thought it must be something along the
lines of what you mentioned with include order causing the
problem however I don't see how this can be the case as
the type is included from one point only.
I've tried creating a simple test case but have been
unable to do so.
Gary.

Would it be possible to try this without precompiled headers? I'm just

I've already tried that, I've also tried to create a

Is there any way you could send us a small, self contained repro for this.
I've been playing with it a little, and haven't had any luck. I'm curious
enough about this, but really need to play with it and debug it.
If you have such a repro case, please send it directly to me. Just remove

Hi,
I am getting a strange LNK Error 1215 saying
fatal error LNK1215: metadata operation failed (8013110E) : Database file is corrupt and may not be usable.
when I am trying to declare any function in my entire project .. sometimes I reset some events it works fine ... It even happened when I tried to declare variables and used .. When I used the same code in the page load event it worked .. Dont know what is happening ? Pls help me ........ This is a real showstopper for me as I am almost on the delivery stage ..... Please please help me ...
Thanks in advance

I think I can solve your problem, same thing happened to me...
Let me guess. Your project started out under one version of the compiler
(say, 2002), and you loaded it up into another one (say, 2003), and it
converted it for you. Well, in my case, this conversion was not perfect, and
2 weeks later I also got random error 1215 errors. The compiling errors you
get will be random and not make sense (e.g., you add a line of code and
something totally unrelated that use to work stops working).
Solution? Create a BRAND NEW project under the new compiler (in the example
above, 2003) of the same type, copy your source over, and it should work
now.
This might also happen converting to 2005, but my experience was conversion
from 2002 to 2003. The weird part is it all worked great until 2 weeks
later, so that really made it tough to figure out what went wrong! The point
being that you might have converted your project a long time ago and this
still could be the cause.
By the way, if you look down lower in this newsgroup, around October 19th at
2:16PM, you'll see a thread I started when this happened to me called
"LINKER ERROR 1215"...
Let me know if that was your problem too... : )

We are trying to build a managed C++ static link library containing several classes which are members of a namespace. The build of this library seems to work OK. No errors.
We then try to use this library in a managed C++ application and get the following linker error.
LINK : error LNK2020: unresolved token (06000002) TestLib.TestClass::GetTemp

When creating a Managed C++ DLL using the Visual Studio 7.1 Solution
Explorer (by selecting Add New Project and then either choosing Class
Library (.NET) or Windows Control Library (.NET)), the IDE sets the
/MT(d) compiler switch (statically linked multithreaded C runtime
library) by default. This is fine with me, as it relieves me from having
to redistribute MSVCR71(D).DLL with my application.
However, as soon as a single runtime...

Hello,
I having having oodles of trouble using the std lib in my MC++ (VS.NET
2003) Class library. I figured out a simple sample to reproduce the
errors I am having. Create a MC++ (VS.NET 2003) class library and type
in the following code below:

Hi!
I'm currently developing a DLL that makes use of C++ and .net (mixed) using
Visual Studio 2003.
Now, as I wanted to move to the new Visual Studio 2005, I converted this
project into the new format (compiling with /clr:OldSyntax): everything works
and compiles fine.
Unfortunately, I cannot link to the newly created DLL from any other
application/DLL: LNK2019: unresolved external symbol. I've checked the DLL

Hi, Gurus,
I recently attempted to build a .Net forms application, that links
with old style unmanaged C++ static libs.
Of course I had to recompile the static lib projects to link properly
with the managed application.
My questions are two fold:

Hello,
I'm running into a linking problem when trying to build a dll like so...

These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
