The basic_ofstream ctor that takes a filename uses a const char* parameter for the name, so passing a wstring or Unicode string for the name won't work.

I see that basic_ofstream takes a filename of const char* parameter, so could you give me a solution to handle (open,close,read,write) a file which has a UNICODE string filepath using std::iostream.
Thanks a lot for ur advice.

For what?
Why did you ask me for what? I don't know!

Simply don't export the functions or classes.

Hi,
I created a generic ATL COM Dll with an Interface and Event. I'm having trouble setting it up to receive the event notification in my client container of a console application. I tried adding a class derived from IDispEventImpl and added the Event Sink map. Anyone know the correct steps in doing this?
Regards,
|

Hello Anthony9887,
Can you be more specific about the trouble you are facing ? For example, does your application crash when it is supposed to receive the event ? Does your application termiate before the event is received by the sink ?
The correct steps to resolve your problems may depend alot on the nature of your problem.
Thanks,
Bio

Anybody can help me?

Scott Meyers in his book "Effective STL" says vector<bool> is not really vector - it's a bitset and it uses proxy when you try to address an element. You cannot use it like an array.
Try different element type instead.

Or use std::deque<bool> instead

I have an active control which is published. Now I want to add two new methods to this control to provide new functionality. Just like COM is the activex immutable ? If yes, how do I achieve it. I mean we declare new interfaces in COM when providing new functionality and QueryInterface determines whether to use the new functionality exists or not. How can I achieve this in activex control.

It's suppose to be hard, otherwise anybody could do it!

I have an atl application that uses an activex control which I create at runtime. I am currently using #import. Now I have a new version of the activex which has some new features, I would like the option of using either of them based on some config setting somewhere. Don't think #import will work in this scenario. Any help is greatly appreciated.

OK, following on from the char -> wchar_t question earlier, does anyone know of a neat STL-friendly way to perform UTF8 encoding/decoding? Currently I use the MS character encoding macros, e.g.:
wstring str = CA2W(utf8_string, CP_UTF8).m_psz;
But I'd like to use something that is a bit more platform independent!

AFAIK STL doesn't have UTF-8 support because the elements in a basic_string have to all be the same size, and the UTF-8 encodings of characters have variying sizes.

Never mind. You can store a utf-8 string as a sequence of bytes in std::string, just need to know which functions operate correctly on such a sequence and which not.
As for the conversion, I have been writing an article on platform-independent STL friendly utf-8 string operations for months, but I just can't make myself finish it

In the Microsoft stl libraries, localization uses C interface. The locale class calls setlocale function. And it cannot work with UTF-8.
From the Remarks section on the setlocale function reference:
"The set of available languages, country/region codes, and code pages includes all those supported by the Win32 NLS API (except code pages that require more than two bytes per character, like UTF-8)."

Yeah once again about it!
I know, there is a way to do it using crt function mbstowcs. The first thing I do not like about it I have single-byte character string (in the cp1251 encoding for example). The second it's not about stl.
