I need to dig up a copy of the standard to see if this is compliant and makes since, because having template parameters that can only be of a single integral type is illogical.
I think there are two pertinent ideas here - firstly, files are streams of bytes (that's the basic concept underlying file streams in C++), which is why they always convert to/from bytes. Secondly, codecvt facets can be used on their own, without streams.
So, say you'd read in a file converting from a byte stream to (say) UCS-2. Then you want to write the UTF-32 equivalent to a file. You could use a codecvt facet that could convert from UCS-2 to UTF-32. The example code in the codecvt::in documentation on MSDN[^] shows this sort of scenario.

Hi,
I am looking for a possibility to have a two way associative array. What I mean is that I would like to have an array say
My2WayArray<int, string=""> _twoWayArray;
and I can do the following
_twoWayArray["user1"] = 123;
_twoWayArray["user2"] = 456;
and
_twoWayArray[123] = "user1";
_twoWayArray[456] = "user2";
this way I will be able to lookup a user if the integer (used as user id) is specified and integer id if user name is provided.
I don't want to use it anywhere, it is just out of curiosity.
While I am posting this question I am trying to figure it out at my end.
Thanks and Regards

It's a pity they don't have something like this in the .NET collection classes. And it doesn't seem to exist in the third party libraries either.

Probably be quite difficult to port the approach used in Boost - one of the first comments I saw in the bimap headers was:
Once you're using the words 'mpl' (== C++ template metaprogramming library) and 'magic' together, there's little to no hope of translating the code directly to another language. I suspect some form of code generator would be the best bet (I seem to remember a container generator being written by someone before C# got generics - that would be similar).

Thank you Andy and Stuart for the reply.
I was looking for boost bi-map type functionality.

Hi,
I need to implement the RPC in windows XP based system and I created an IDL file which contains the RPC calls and i created stub files. While compiling with server and client application it shows "You need a Windows NT Version 4.0 or Later to run this stub".But i am using Microsoft Visual C++ 6.0. Can anyone help to solve this problem?
Thanks,
S.Suthakar

You probably need to set WINVER[^] to reflect you're using Windows XP, rather than Windows 98, which was the current version of Windows when VC6 came out.

What Stuart said and depending on what you are using you might need to have an updated Platform SDK[^] from the original VC6
|

|

I am using original version. The auto generated code only shows the error(defined in #).if i remove that then it is compiled.

I have no new information. Follow the advice previously given by myself and Stuart.

Good point - I forgot that one. So long since I used VC6....since I moved to VS2003, I've always used a Visual Studio newer than my standard target (Windows 2000 - we've not managed to make the giant leap to XP or Vista at the company I work for).

Hi,
I compiled the idl file and it creates server and client (ie client_c.c and server_s.c) stub files.Client stub file is working properly in application.But In server stub file Interface definition is not implemented(generated code).(I created idl file project type is ATL COM AppWizard and server type as Service).
Regrads,
Suthakar

What do you mean by 'not implemented'?
I just tried a quick sample of IDL, which I processed with midl /server stub /client stub a.idl - seemed to have the correct server marshalling code.

I just compiled .idl by vc++ editer itself.It creates the client and server stub files.I want to know that whether i should compile .idl file using midl compiler only or the the first is enough.
Not implemented -->The function(idl) definition is implemented in server stub file (in my sample code).But original code it was not there.

VC++ uses MIDL. That's fine.

Can you explain what you mean by 'But original code it was not there'

I am already having some sample code for RPC which executes perfectly.But my RPC server stub code, implementation of idl function definition (ie auto generated) was not there.
|
|
|
|
|
So - do you mean there was no whatever_s.c file? Or that it was empty? Try posting your IDL, and look in your VC++ project settings for that file to see what the command line to compile the IDL is and post that.

Hi, now server is working fine but in client side it through an exception while running with breakpoints in client stub file.The idl file is as follows
[ uuid (id),
version(1.0),
pointer_default(unique)
]
interface myidl
{
typedef struct
{
int data;
}DATA_ST;
void function([out] [in] DATA_ST *,DATA_ST);
}
NdrNsGetBuffer( (PMIDL_STUB_MESSAGE) &_StubMsg, _StubMsg.BufferLength, myidl__MIDL_AutoBindHandle );
while running this above function it through the exception " Runtime reported exception 0x6e2 = 1762.I want to know how the synchronization is maintained between client and server.

suthakar56 wrote: I want to know how the synchronization is maintained between client and server.
By maintaining a single thread of control between client and server - the calling thread on the client side waits while an RPC call is made.
suthakar56 wrote: void function([out] [in] DATA_ST *,DATA_ST);
Should that be
void function([out] DATA_ST *,[in] DATA_ST); ?
suthakar56 wrote: Runtime reported exception 0x6e2 = 1762
Error 1762 == RPC_S_NAME_SERVICE_UNAVAILABLE. Means it can't find the server, I think.

Hi Stuart, The problem is solved.As a beginner,I missed the .acf file.So that the problem is created.Now this is working fine.Thank you for your replies.

Good! Well done for sorting it out!
suthakar56 wrote: As a beginner,I missed the .acf file
I've never used an acf file when I've used MS-RPC - I guess the situations where I've used RPC have been simple enough for me to get away without one.

Hi There !!!
Let's find someone who could help me on this problem.
I have created on VS2005 under Windows Vista a new Visual C++ ATL Server Web Service Project with:
Blob Cache
Session Services (Memory-backed session-state service)
I compiled the project sucessfully. Then, i opened IExplorer and access de URL to generate the WSDL.
The WSDL of the web service was generated with sucsess.
This is my problem:
With this simple and basic project, i changed the configuration properties to support Common Language Runtime Suport, Old Syntax (/clr:oldSyntax)
The compilation of the project was made successfully.
The problem was when i go to access the web service to generate the WSDL via web browser.
I access the URL (something like: http://localhost/ATLWS1/ATLWS1.dll?Handler=GenATLWS1WSDL) on IExplorer, and the web browser hangs and no result is returned.
Just a page indicating that "Internet Explorer cannot display the webpage".
There some dependency or configuration missing to support CLR ?? I tried the same scenario on Windows XP and this works fine.
