Hi,
I was in need of MD5 hashing to one of project, and found the URL http://www.md5hashing.com/ useful. Downloaded the C++ files and included the same to the project and able to hash strings.
But the problem I am facing here is, it works fine with 32 bit machines but it fails in 64 bit machines/OS. So please let me know how to resolve this problem. Is there any other set of code available which works for bit 32 bit and 64 bit?
Thanks,
Nandu.

Hello guru developers,
I have a project which i have to use a lot of memory allocation, the project works fine except when there are a lot of data the process is killed by Linux, i don't know why? For example this example: it should exit when there is no free memory, but it is killed after some time when i run this program,
Does anyone has any idea how to solve this problem in Linux?
thanks in advance
#include <stdio.h>
#include <stdlib.h>
#include <iostream>
#include <string>
#include <list>
#include <time.h>
using namespace std;
struct tree_node
{
list<tree_node*> leaf;
char data;
short IsEndPoint;
};
int main()
{
try
{
for (int i = 0 ; i < 9999000; i++ )
{
tree_node* t = new tree_node[1000];
printf("id: %d \r ", i);
}
}
catch(...)
{
cout<<"test"<< endl;
exit(0);
}
cin.get();
return 0;
}</time.h></list></string></iostream></stdlib.h></stdio.h>

I never programmed with gcc in linux so I might be wrong. I am guess that new operator does not throw an exception but terminated the program when cannot allocate memory.

how could you catch exception memory is full? is there any way in c++ for windows? not for linux, it must be same in linux

Well you already have the code to catch the exception...using a catch block. When new operator cannot allocate memory then it throws std::bad_alloc exception. Also the value of returned pointer is NULL.

Thanks for reply,
I run this code under Visual c++ 2005, it does not throw any exception, it crashes computer, do u know why it crashes computer?
Thanks

If my calculation is correct then you are requesting about 260.74GB of memory!!! Which of course cannot be allocated. I don't think that your program should crash, instead you should get nice error from windows stating Windows is running low on memory so termination your program.
Just out of curiosity what are you trying to do?

I took such a large memory on purpose to test bad allocation exception, i figure out how to do that,here is my final code,
this works,
# include <iostream.h>
# include <ostream.h>
# include <new.h>
#include <list>
struct tree_node
{
std::list<tree_node*> leaf;
char data;
short IsEndPoint;
};
void MyHandler()
{
std::cout << "MyHandler Called... " << std::endl;
throw std::bad_alloc();
}
int main()
{
std::set_new_handler( MyHandler );
char* ch;
try
{
for( unsigned long Idx( 0 ); Idx < 0xffffffff; ++Idx )
{
new tree_node[10000];
printf("id: %d \r",Idx);
}
}
catch( const std::bad_alloc& e )
{
std::cout << e.what() << std::endl;
}
std::cin.get();
return 0;
}
</list></new.h></ostream.h></iostream.h>

Hi all. I have a question about socket. Hope everybody helping me ^^
In socket, I have a simple Server Chat and Client Chat. When a socket in server side accept an connect from Client. And Client side connect to server. Then the socket of both server and client action the Send() command. Is it right ? If it is right, how can I ignore the message I received at that time ?
Thanks

What are you talking about?
Ignore WHAT message? And what do you mean by "message"?

I'm using above mentioned ctrl in my dialog, it is as simple as possible, I populate only one column. My problem is that when I click header to trigger sorting action nothing happens (sort arrow is drawn correctly)?
In property's panel Sort is set to none!
Any help!
Thanks in advance!

It seems a coherent behaviour.
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

"In property's panel Sort is set to none!"
It seams it doesn't matter how I set it (None/Ascending/Descending)it's only for starter, my main concern is that sort do not work when I click my mouse over the header control!?

From the List View docs:
Unless the LVS_NOCOLUMNHEADER window style is specified, column headers appear in report view. The user can click a column header, causing an LVN_COLUMNCLICK notification message to be sent to the parent window. Typically, the parent window sorts the list-view control by the specified column when this clicking occurs. The user can also drag the column guides between the headers to size the columns.
So, are you handling the LVN_COLUMNCLICK notification? If not, nothing very much will happen.
(If it's any consolation, I expected to find some sort of LVN_ISONETHINGBIGGERTHANANOTHER notification, but there you go...)
Iain.
Plz sir... CPallini CPallini abuz drugz, plz plz help urgent.

1/ No, because if I do email you amazingly great advice, noone else would see it and benefit.
2/ If I reply to you here with also amazing advice, noone would see it.
3/ I'm kinda busy today. Others may be able to help you better.
4/ I've never actually sorted a list control. When I have used the things, I want to control the order of presentation. My previous answer was an example of "here's the documentation. It prehaps has useful information..."
The advice I *will* give you is to post a new question on this forum, after reading the "how to post" post at the top of the forum. Then you will get an email notification of any replies, and others can benefit too. You do want others to benefit, don't you?
The only thought I can think of is that you need to know how to sort on one column first before trying multiple columns.
Iain.

I tried to construct a Bitmap object using a gif file.
And use Graphics::DrawImage to draw it in the size other then the original one.
It displays a black box.
Doesn't GDI+ support this?
If not, does CImage support this?
The 3rd party support will be the last resort.
Thanks.

Have you tried drawing it normally (without scaling) to make sure you have it loaded and are trying to draw it correctly?
Peace!

It's ok without scaling.

Then I have no idea... Graphics::DrawImage(...) is supposed to support scaling all by itself, so if you constructed the Graphics object using the Image object that contains the loaded GIF, it should work...
Peace!

CPropWnd is derived from CDockablePane, and CNavWnd is derived from CWnd.
Here is the handler for the "show navigator button":
void CPropWnd::OnShowNavigatorWnd()
{
CNavWnd *pNav = new CNavWnd(this);
CRect rc;
rc.SetEmptyRect();
if (!pNav->Create(NULL, NULL, WS_VISIBLE | WS_OVERLAPPEDWINDOW, rc, this, UINT(-1)))
{
ASSERT(FALSE);
}
GetWindowRect(&rc);
pNav->SetWindowPos(NULL, rc.right + 5, rc.top, -1, -1,
SWP_NOSIZE | SWP_NOZORDER | SWP_SHOWWINDOW);
pNav->UpdateWindow();
}
Why the navigaotr windows can't be shown?
