Please be more specific.  What EXACTLY are you having a problem with?

I have taken an application that we have developed for years, lastly under 
Borland Builder 6 and moved it to a new PC with CodeGear C++ Builder 2007. 
I open the project and it converts to a new project file.

Some modules build fine while one generates 51 errors.  The thing is the 
errors are showing up in system include files.

The first set of errors are:
[BCC32 Error] cstring(29): E2316 'string' is not a member of 'std'
    ( The line in cstring is:     using std::string;   )
[BCC32 Error] cstring(29): E2272 Identifier expected
[BCC32 Error] xstring(8): E2041 Incorrect use of default
[BCC32 Error] xstring(8): E2428 Templates must be classes or functions
[BCC32 Error] xstring(8): E2141 Declaration syntax error
[BCC32 Error] xstring(22): E2303 Type name expected
[BCC32 Error] xstring(22): E2275 { expected
[BCC32 Error] xstring(22): E2272 Identifier expected
[BCC32 Error] xstring(23): E2272 Identifier expected
[BCC32 Error] xstring(23): E2275 { expected
[BCC32 Error] xstring(27): E2139 Declaration missing ;
[BCC32 Error] xstring(29): E2139 Declaration missing ;
[BCC32 Error] xstring(214): E2139 Declaration missing ;
[BCC32 Error] xstring(326): E2303 Type name expected

If we take the first one the full parser context is(comments in brackets 
below):
    Annotation.cpp(3): #include Annotation.h
        ( There are no other includes or defines before this one.)
    Annotation.h(12): #include ..\General\vector_p.h
        (There are only system includes before this one.
            #ifndef AnnotationH
            #define AnnotationH

            #pragma option pop )
    vector.h(18): #include c:\program files\codegear\rad

    xlocale(5): #include c:\program files\codegear\rad

        ( The error is in this file. )

I'm  not sure where to go with this one.

That is rarely ever recommended.  There is always problems with conversion. 
You should always create a fresh project in the new IDE and add your 
existing source files to it instead.

Please show the actual code that is failing.

The STL's <string> header (not the RTL's <string.h> header) was likely not 
included before reaching that point.

Ok... now I'm really confused.  Out of despiration I started a new DLL 
project.
When I do this it creates me a file1.cpp.

So now a I have a new project, new directory, new file.  I build the file 
and it builds without error.
The top of the file looks like:

//---------------------------------------------------------------------------

#include <vcl.h>
#include <windows.h>
#pragma hdrstop
//---------------------------------------------------------------------------
//   Important note about DLL memory management when your DLL uses the

Now all I do is add the include for strings.

//---------------------------------------------------------------------------

#include <vcl.h>
#include <windows.h>
#include <string>
#pragma hdrstop
//---------------------------------------------------------------------------
//   Important note about DLL memory management when your DLL uses the

and now I'm back to my 51 errors!

So this has to rule out anything I have in my old code, old includes etc! 
So what is with the #include <string>!

This is a new computer, new installation of the compiler.  I should have 
tried this simple test two days ago but figured it was in my code.

Any thoughts?

Don't put it above the #pragma statement.  Put it below instead:

    #include <vcl.h>
    #include <windows.h>
    #pragma hdrstop

    #include <string>

I just tried doing exactly the same thing and I get a clean build - no
errors or warnings. Doesn't matter if the #include <string> is before
or after the #pragma hdrstop.


It sounds to me like you are somehow calling a header from a different
STL implementation. Check the include path for your project and make
sure that it points to the Builder 2007 include directories before any
other directories and try again.

Another thing you could try is turning off pre-compiled headers to
make sure that the ide is not using a bad pch file.

If that does not work, you can zip up the entire demo project and post
it to the attachments group and post a note here so that we can see if
there is something else going wrong.
