IMHO such a discrepancy would be too gross, even for VC6.

yes, probably, but it's not *THE* compiler to test the standard !

Not according to the STOSx instructions. Of course, I only use it to initialize POD types to 0. Otherwise, I'd use memset().

Sorry no STOS here:
...
const int N = 10;
int a[N]={7};
00401003 xor eax,eax
00401005 push esi
00401006 mov dword ptr [esp+8],7
0040100E mov dword ptr [esp+0Ch],eax
00401012 mov dword ptr [esp+10h],eax
00401016 mov dword ptr [esp+14h],eax
0040101A mov dword ptr [esp+18h],eax
0040101E mov dword ptr [esp+1Ch],eax
00401022 mov dword ptr [esp+20h],eax
00401026 mov dword ptr [esp+24h],eax

No luck (there isn't such insruction). On the other hand, the output of this program [^] confirms my assumption.
See also Sandip's post [^].
I should admit I was very surprised by such a behaviour.

and what about {0} instead of {7}, and in Release Mode, not in Debug Mode ?

See my added remark here [^].
BTW my tests were of course performed both in Debug and the Release mode.

0 works fine.

Same results for both 0 and 7. This is why I only do it when setting things to 0. I use memset() otherwise.

It is just a side-effect of default (int) initialization: you're actually initializing only the first array item. Try the following code:
#include <iostream>
using namespace std;
struct MyStruct
{
MyStruct():_i(-1), _j(0),_k(-1){ }
MyStruct(int a):_i(a), _j(a), _k(a){ }
int _i,_j,_k;
};
void main()
{
int i;
MyStruct a[5] = {0};
for (i=0; i<5; i++)
{
cout << i << ") {" << a[i]._i << ", " << a[i]._j <<", " << a[i]._k << "}" << endl;
}
}

For structs, I'd use memset(). I only use 0 for POD types.

I think you are trying to do something like this..
class A{
int TModels[3];
public:
A():TModels[1](0){}
};
int main(){
A a;
}
which is giving you above error:
As per my knowledge there is no (standard) C++ way of doing this. Array initializers do not exist for classes. So prob you can do it somewhat like this:
class A{
int TModels[3];
public:
A(){
for(int i=0; i<3; i++)
TModels[i] = 0;
}
};
int main(){
A a;
}
Hope it helps you

Hi,
I am writing a client application to connect to servers that have shares information.
I found out that servers will not allow data to be sent via different sockets after login from one socket.
So, I think asynchronous model using the same socket to communicate with the server for the requests should work. Here I am planning to use a separate thread for each request.
Here, if 2 threads are present and each send diff requests. Now server sends the responses. When checked with this model, the responses were received by each thread were not theirs. (this might be because both the threads are receiving on the same socket.)
Here, my question is how to know that the message received doesnt belong it OR how to make the thread receive the response to the request it posted?
Please help on this ASAP, its urgent.
Many thanks in advance.

Yes.

No.

No, don't do it this way, use an IOCP model.
There are many articles on this site on how to impliment IOCP.

The idea that I can be presented with a problem, set out to logically solve it with the tools at hand, and wind up with a program that could not be legally used because someone else followed the same logical steps some years ago and filed for a patent on it is horrifying.

Does the application crashes in the release build due to the below mentioned warnings. because it gives the following message
debug build is fine.

Hi,
I had the same warning. See this thread[^]. Hope it helps.

Hi all,
How can I execute .bat file using vc++.
I am trying to execute it by using ShellExecute() function but it is not executing.
ShellExecute(NULL,_T("Open"),"_T("D:\\myBat.bat"),NULL,NULL,SW_HIDE);
It is returning less than 32, but if it is successfully executed it should return greater than 32.
Please provide me the solution.
Thanks.

You can use the return value to find out what went wrong. Have you tried that?

if it's not executing, how can it return 32 ?
maybe you just don't see the windows because of the SW_HIDE. what if you display it with SW_SHOWNORMAL ?
also, how do you check the return code ?

I am receiving the returning value in an integer. It is executing but giving me the error 32 "process can not access file because it is being used by another process."
