I have been trying another sample for CMap which was something I wanted to learn but my VC 6 compiler will not compile it. Even though I have the #include <afxtempl.h> it will not acknowledge it. The browser doesn't find CMap either with a BrowseGotoDefinition key for whatever that's worth, not much as Joe would say. CMap<CStrng, CString&, CPoint, CPoint&> MyMap2; //error C2065: 'CStrng' : undeclared identifier MyMap1[CString (_T ("Vertex1"))] = CPoint ( 0, 0); It may be the sample though because this will compile and browse CMapStringToString MyMap2; // compiles ok The first sample may be flawed, but it looked interesting since it will allow a user defined type into CMap. I looked at structs in std::map but I am so weak in template language that I will probably just have to pull off and read some text for a few days. I have a legal bought copy of VC 2005 and I am definitely going to install it this weekend. I dread getting acclimated to a new environment since I had grown so used to the old VC 6. Thanks for the help guy.
From: Joseph M. Newcomer on 10 May 2010 21:43 You can't really use CString in a non-MFC app without including <atlstring.h>; if you have not included that, then you won't have CString defined. Note that none of this has anything to do with the std:: namespace, but with the failure to have included the string library. You should not mix MFC and non-MFC idioms in non-MFC programs. It is OK to use std:: in an MFC program, but not to use MFC constructs in a non-MFC program. Note that if you are generating a console app, you can check the "use MFC" option when you create the app, and you will get all of the MFC library (which is overkill for a console app). Or you can figure out which ATL header files need to be included to get the capabilities you need. But the odd mix, that includes CString and cout, is more than a little weird. joe On Mon, 10 May 2010 18:38:40 -0400, "RB" <NoMail(a)NoSpam> wrote: > >> Doug Harrison wrote >> The identifiers cout and endl are also in namespace std, so you need >> std::cout << array[j] << std::endl; >> Kind of a pain, but you could employ using-declarations to ease things: >> using std::cout; >> using std::endl; >> This brings just these symbols into scope.

Good move! > I dread getting acclimated > to a new environment since I had grown so used to the old VC 6. You will miss VC6's ClassWizard and snappy IDE, but you will get several good things, like a better C++ compiler, better libraries, and debugging visualizers. Giovanni |
