Hi!!
This is the code of my project..For exm..First time when i call function then
webdocupath = D:shah\myproject\webdocu\parth...ok now when i will call second time then

D:shah\myproject\webdocu
and so on..

I want at any time webdocupath =D:shah\myproject\webdocu\parth

CString webdocupath,pmysection;

// When resource from this ARX app is needed, just
// instantiate a local CAcModuleResourceOverride
//CAcModuleResourceOverride resOverride;

Are you assigning it a new value?

Based on the code snippet you've shown, it already is global.

You said that the contents changed. What is inside ?
If you don't assign a new value and the contents changed, that means you have a buffer overflow somewhere.

Hi guys. I just have a quick question about the declaration of the socket function bind and the sockaddr_in structure. Both declarations are given below.

int bind (SOCKET s, const struct sockaddr * saddr, int namelen);

struct sockaddr_in
{
    short sin_family;
    u_short sin_port;
    struct in_addr sin_addr;
    char sin_zero[8];
}

My question is: What purpose does the 'struct' keyword serve WITHIN these declarations. (the part in bold above) I've never seen this use of the 'struct' keyword before. Thanks in advance.

Well this one is needed as far as I knnow to store the adress you want to listen, f.ex.

<br />
//adress buildup<br />
SOCKADDR_IN lSockAddr;<br />
memset(&lSockAddr,0, sizeof(lSockAddr));<br />
lSockAddr.sin_family = AF_INET;<br />
lSockAddr.sin_port = htons(8500);<br />
lSockAddr.sin_addr.s_addr = INADDR_ANY;

and afterwards you can check if all initialize went OK with

<br />
if(lSockAddr.sin_addr.s_addr ==INADDR_NONE)<br />
   //error<br />

Sorry. Maybe I wasn't clear about my problem. I'm not asking how to use the bind function or the sockaddr_in structure. I'm just curious why they are declared the way they are. i.e., why is the 'struct' keyword needed in the places I have in bold. It seems to me like it's not really necessary. I'm sure I'm wrong but I don't understand why.

Let me rephrase my question

Well the first "struct" is simply the parameter required when you pass the function. Secondly, it is not uncommon to have a structure that is contained in another structure, that is perfectly legal.

I appreciate your reponses guys but I think you're missing the point of my question. Let me rephrase it.

Observe the 2 following code snippets. Both are almost identical accept one uses the 'struct' keyword in the declaration and the other doesn't.

struct MyStruct
{};

//The keyword 'struct' is commented out below.
void MyFunction (const /*struct*/ MyStruct * pMyStruct)
{
    return;
}

struct MyStruct
{};

//The keyword 'struct' is used below.
void MyFunction (const struct MyStruct * pMyStruct)
{
    return;
}

Despite these differences, both pieces of code compile.

So whats the point in using the 'struct' keyword at all?

Microsoft doesn't use it other functions when passing a struct or struct pointer to a function. So why do they do it in the socket function bind? Is it simply for clarification or is it more important than that?

It's a difference between C and C++.

In C, names declared with struct, union and enum are in a different namespace to the built-in types and typedefs. You have to use the appropriate keyword when you use it, otherwise you'll get an error.

It's very common for a struct declaration to be included within a typedef declaration so that the namespace is 'flat'. In theory you could declare a typedef with the same name as a struct, union or enum.

C++ does away with this: there is no separate struct, union or enum namespace. It's not an error to prefix a type name using struct, union or enum, (not sure about class) but is no longer necessary. I think the compiler is supposed to check, if you do use the keyword, that the type is actually what you say it is (i.e. struct, union or enum).

Stability. What an interesting concept. -- Chris Maunder

This use of the struct keyword is a relic from C where it is a part of the type name.
In C++ it's perfectly legal to omit the struct keyword.

E.g. for C

struct MyStruct
{
    int nFirst;
    int nSecond;
};

int main( int argc, char* argv[] )
{
    struct MyStruct theStruct; /* Quite allright! */
    MyStruct theStructCopy;    /* Unknown type! */
}

and for C++

struct MyStruct
{
    int nFirst;
    int nSecond;
};

int main( int argc, char* argv[] )
{
    struct MyStruct theStruct; /* Quite allright since it's compatible backwards */
    MyStruct theStructCopy;    /* Also allowed  */
}
