well... that's my point. I can't seem to find any way to fix it. It runs but I don't know what logical error I'm doing. It does store the input in the stack but it no longer goes to the next line of codes after the while loop. Please help.. (T_T)

The code snippet you've shown does not compile.

Have you tried pressing F6 followed by the Enter key (twice).

wait. im sorry about that. this is the right code.
#include<iostream>
#include<stack>
#include<string>
using namespace std;
int main(){
stack<string> syntax;
string word;
while (cin >> word)
{
syntax.push(word);
}
cout << "Number of words: " << syntax.size() << endl;
while(!syntax.empty())
{
cout << syntax.top() << endl;
syntax.pop();
}

Hi All,
I want to attempt to block a specific program from establishing outgoing TCP/UDP connections. Thus as the (external) app attempts to make a socket connection, I want to receive notification of the event and have the ability to allow or deny the connection attempt.
(I know this is basic firewall functionality I am referring to here, but there is no firewall on the market that can do exactly what I want, when I want, and how I want it for this specific program)
I have seen the packet filtering API that is provided by Windows, but that only seems to filter on IP's and Ports. I want to filter on application !
Can anybody please point my nose in the right direction here.
Thanks

Try implementing a Layered Service Provider. This is a DLL that gets loaded by every application that uses Winsock.
Look up Winsock Layered Service Provider, or LSP.

Hi all,
I am currently working a specific hardware device and the device header files do not support some of the standard C string routines. Thus I am struggling to convert a int to a char*.
Thus, how can I perform this action without making use of itoa, printf, sprintf ??
Many thank in advance
Kind regards,

Examine the source code of a standard C-RTL and steal^H^H^H^H^H, er... get some inspiration from... their implementation.

Here's how the CRT does itoa(), with all the error/buffer overflow checking stripped...
void integertoascii(int n, char *buf, int radix)
{
char *pbuf = buf;
do
{
unsigned int digit = (unsigned int)(n % radix);
n /= radix;
if (digit > 9)
*pbuf++ = digit - 10 + 'a';
else
*pbuf++ = digit + '0';
}
while (n > 0);
*pbuf-- = '\0';
do
{
char temp = *pbuf;
*pbuf = *buf;
*buf = temp;
--pbuf;
++buf;
} while (buf < pbuf);
}

I am installing my mfc based application through a .msi file.
i want to know how to close a running application before uninstallation???
|

Implement a small DLL that closes the application by sending a WM_CLOSE message to the main window.
Then call the DLL through a Custom Action in your MSI.

Hello everyone,
How to get the preferred load address for a DLL? Suppose I just have the binary DLL and no source code?
thanks in advance,
George
|
|
|
|

You can use ListDLLs[^] to list currently loaded dlls.
If you use the -r switch it will flag up any dlls that have been relocated, and give you their preferred base.
Or Process explorer[^] has a dlls window which lists all the dlls loaded for each process, their base address, their preferred base address, and colours them yellow if they have been relocated.

Hi Simon,
Which Window in Process Explorer lists loaded DLLs for a process? I can not find out. 
regards,
George

From the view menus, select the "Show lower pane options"
Then again from the view menu select "view->Lower pane view->dll"
|
|
|
|
|
Thanks nave,
DLL is displayed, but the DLL properties only display load address, no preferred load address. Any comments?
regards,
George
|

You can select that column also.
take the select column option by right clicking on the header of the lower pane. Select the "Base" and "Image Base" from the list. The "base" is the address at which the dll has actually loaded and "Image base" is the prefered base address.
You can also use the dependency walker to find the prefered base address.

Thanks nave!
I have found out, very good tool!

George

On my system at least,
dumpbin /headers iain.dll
then look at the image base value.
That's with VS6 - no idea if the utility is still around for later versions.

Though I'd look at the sysinternals tool, as they're more digestible!
