You probably have in your code: #include <3rdPartyString.h> // declaration of 3rd party string type #include // declaration of std::string using namespace 3rdPartyNamespace; using namespace std; ... string myStr; // which string type? Compiler now doesn't know which string you want to use - one from 3rd party library or STL one. You can resolve this ambiguity by prepending namespace name to the type: 3rdPartyNamespace::string myStr; // if you want to use string from 3rd party library or std::string myStr; // if you want to use STL string Never place using namespace namespace_name; in headers but try to avoid it in source files as well. The best practice is to prepend type name as this does doesn't pollute your current namespace with the other one thu

When compiled with #include I get the error error c2872 ambiguous error C2872: 'IServiceProvider' : ambiguous symbol. Most of the resolutions seems to be suggesting moving #include like the one here -> Ambiguous references, but I dont have those includes. All I have is: using namespace System; using namespace System::Configuration; using namespace std; #include How do I debug this issue ? c++-cli share|improve this question asked Oct 22 '10 at 20:21 anivas 3,93231629 add a comment| 1 Answer 1 active oldest votes up vote 26 down vote accepted You do, indirectly, marshal.h includes it. It dumps an enormous amount of identifiers in the global namespace. The macros are especially awkward, lots of them match names used in the framework. Lots of things that marshal.h does can be done by the Marshal class as well. But I can't help you with that, you didn't mention why you want to use it. You can solve this particular mishap by putting the #include directive before the using statements: #include using namespace System; using namespace System::Configuration

easy but it wasn't working. [Note: Microsoft factored CString from MFC several years ago, so CString can now be used standalone. Super handy class.]I started with what I thought was a reasonable statement:
#include "cstringt.h"
This gave me numerous errors, starting with:C:\Program Files\Microsoft SDKs\Windows\v6.0\Include\ocidl.h(6238) : error C2872: 'IServiceProvider' : ambiguous symbol
C:\Program Files\Microsoft Visual Studio 8\VC\atlmfc\include\atlcomcli.h(370) : error C2872: 'DISPPARAMS' : ambiguous symbolWith a little research, I determined I was using the wrong include file. So I switched to:
#include "atlstr.h"
When I tried to do that, I received similar errors:
C:\Program Files\Microsoft SDKs\Windows\v6.0\Include\ocidl.h(6238) : error C2872: 'IServiceProvider' : ambiguous symbol
C:\Program Files\Microsoft Visual Studio 8\VC\atlmfc\include\atlcomcli.h(370) : error C2872: 'DISPPARAMS' : ambiguous symbol
Several other posts inquiring about the same errors received no answers.The problem is caused because the Microsoft SDK (aka Platform SDK) and mscorlib both have definitions for these classes.The solution is to take the #include file that caused the problem and make sure it is placed before any "using namespace" statement. In my case, that meant moving #include near the top of stdafx.h. Posted by Jim Beveridge at 12:05 PM 12 comments: GoogledMay 7, 2009 at 12:31 AMFinally one quick solution after lot of googling.
