Question about the MFC and iostream

[txjump]

Hi,

Im new to using the MFC but have been using plain ole c++ for a while. so im used to using <iostream> for cout but now im trying to build some apps that use the MFC and everytime i try to include the <iostream> file and

#include <afxwin.h>      // MFC core and standard components
#include <afxext.h>      // MFC extensions

i get the following errors:
nafxcwd.lib(afxmem.obj) : error LNK2005: &quot;void __cdecl operator delete(void *)&quot; (??3@YAXPAX@Z) already defined in libcmtd.lib(dbgdel.obj)

Debug/managedC++app.exe : fatal error LNK1169: one or more multiply defined symbols found

//********************

ive looked up this error before and tried to get ride of it properly but the only thing ive found that works is to use &quot;FORCE&quot; in the compile.

it doesnt matter if i also have using namespace std; in my code...ive tried to exclued and reinclude files in a different order...grrrrrr

can someone tell me why i cant use the includes together or tell me how to fix the problem in the .Net environment? any suggestion would be appreciated!

thanks
