• GWILSON1981 friend class question

  Hi I was working on a project that required a linked list for a class.  I thought that adding another variable to the node class would be helpful during the project to keep track of something but the way I have implemented it seems to not be working.  I was under the impression that friend classes can see the private data of the class it is friends with.  My linked list class even displays this working with the data variable (show ...Show All

• azfar dllexport and function templates specializations

  Let's say I have the following template function:   Template <typename T> void Fun(T t); I'd like to be able to implement some specializations of Fun in a first DLL (DLL_1), some other specializations in a second (DLL_2), and still some other in a third (DLL_3), but DLL_2 and DLL_3 may make use of specializations implemented in DLL_1. So in DLL_2, Fun<T> may be both imported and exported, depending on T. I somehow managed ...Show All

• Preston Park Unlinking the CRT...

  Here's a fun question: how do I get the CRT out of a project, utterly and completely The project in question is a mixed-mode C++ DLL. /NODEFAULTLIB leaves me with dozens of link errors to CRT functions that I'm not calling from my code so I'm assuming the compiler is sneaking stuff in on my behalf (how very kind of it). What functions do I need to implement on my own and how do I do that Some of the more obvious ones like atexit I've already ta ...Show All

• AnaC Managed C++/CLI wrapper returning COM interface?

  I have a Managed C++/CLI clas that contains unmanaged initialization code that ends up with an unmanaged COM interface pointer. I would like to return this pointer back to the 'managed world' as a reference. I have a COM interop dll that defines this interface (generated with tlbimp.exe) but of course the type of the pointer that the unmanaged code has comes from the .h file that midl.exe generated based on the IDL file. What would be the mos ...Show All

• _Donnie-Darko_ C2664 cannot convert from 'System::String ^' to '_bstr_t'

  This may seem silly, but how do you convert from a managed System::String to BSTR or _bstr_t or ANY other string (const char *, etc.).  This would be required to call an old COM interface from a managed C++ app. If this has already been answered I apologize.  I searched but did not find anything. Helper functions have been known to help. Helper functions and constr ...Show All
