Hi again,

I fixed the previous errors as it appeared I had the #include <mysql++.h> in the wrong position. By putting it at the very start of the program rather then after including the standard header file, all the errors went away. But now I have a new error! My include code looks as follows,

//Login.cpp #include <mysql++.h> #include "StdAfx.h" #include "Login.h" #include "Main.h" // The second form that opens after login using namespace APOSSv2; // APOSSv2 is the project name

And now when i type mysqlpp:: it comes up with the autofill box and gives me the option to use Connection, but when I put the code

mysqlpp::Connection con(false);

into a function and compile it I get compile errors (it compiles and runs fine without mysqlpp::Connection con(false); code):

.\Login.cpp(15) : error C2653: 'mysqlpp' : is not a class or namespace name .\Login.cpp(15) : error C2065: 'Connection' : undeclared identifier .\Login.cpp(15) : error C2146: syntax error : missing ';' before identifier 'con' .\Login.cpp(15) : error C3861: 'con': identifier not found

I've had a look around the web and most of the solutions are "make sure you have included the header file" which I have done as far as I can see. The strange thing to me is that why would it autocomplete and then say it can't find the namespace. I thought it might still have something to do with the placement of the #inlcude statement, so i try it in the last possible position in between stdafx.h and login.h,

//Login.cpp #include "StdAfx.h" #include <mysql++.h> #include "Login.h" #include "Main.h" using namespace APOSSv2;

which results in errors as follows (the error lines are too long to put in an email, but they start like this...

Login.obj : error LNK2028: unresolved token (0A00084D) "void __cdecl mysqlpp::create_vector<class...

And if I include it anywhere below #include "Login.h" I get the [[[[ error C2872: 'IServiceProvider' : ambiguous symbol... ]]] which was the original problem. I'm very inexperienced with Visual C++ so really don't have much of an idea what is going wrong. A bit of code or a sample project which uses windows forms and mysql++ that I could play with to see where I've gone wrong, or any fixes to the above problems would be great.

Thanks,
