Can you clarify what you mean with "computer priority shown emergency"?

actually server have priority 0 to 7 whc catagories the level of access by unauthorizes person and save it at syslog txt file! As below:

 Numerical         Severity<br />
          Code<br />
<br />
           0       Emergency    : system is unusable<br />
           1       Alert        : action must be taken immediately<br />
           2       Critical     : critical conditions<br />
           3       Error        : error conditions<br />
           4       Warning      : warning conditions<br />
           5       Notice       : normal but significant condition<br />
           6       Informational: informational messages<br />
           7       Debug        : debug-level messages

the syslog txt file contain priority and ip address as below:

<133>Jul 26 10:32:48 sensor SFIMS: [1:499:4] ICMP Large ICMP Packet [Classification: Potentially Bad Traffic] [Priority: 2] {ICMP} 192.168.2.25 -> 202.76.239.1

I need urs help that hw to automatically shut down the certain pc by knowing the ip address when the priority 0(emergency) is more than lets say 100 times!

Dll Not Working Correctly

I'm trying to call the SystemParametersInfo() function in User32.dll from my C/C++ code on Win2k but it's not working. I've used the same code to successfully call a function from a different dll (kernel32.dll) so I'm confused. The LoadLibrary command works, but the GetProcAddress command is not, thus I get the output:

started it up...
loaded library...trying to find address of function...
proc addr: 0
couldn't get proc addr

I'm compiling with Visual Studio.net 2003. Any suggestions would be greatly appreciated. Thanks.

Try with "SystemParametersInfoA" or "SystemParametersInfoW"

I'm afraid you are not in a position to write the language yourself, you have to live with the language as it exists. Best you can do is this:

#define NEWLINE \r\n

and then use NEWLINE, or something similar.

In any case, \n won't work, it's \r\n ( or \n\r, I forget ).

Do you want it to be multiline only in your source code

const string TEMPLATE = "These three string literals will be "
                        "concatenated and the result assigned "
                        "to TEMPLATE as a single string";

or do you want it to contain multiple lines

const string TEMPLATE = "These are the first,\r\nsecond,\r\nand third lines";

or both?

const string TEMPLATE = "These are the first,\r\n"
                        "second,\r\n"
                        "and third lines";

I want to create a CEdit as a child window of a CListCtrl when CListCtrl is si created and destroy it when CListCtrl is destroyed.
I declare a member var in CListCtrl like this, CEdit m_edit,
and use m_edit.Create(...) in CListCtrl's constructor or CListCtrl's OnCreate,
but it doesn't work, the m_edit.m_hWnd is 0.

Re: help,can't create windows in constructor and OnCreate

Jose Lamas Rios1-Sep-05 17:07

It won't work in the list control constructor because you need to pass the list's hWnd to m_edit.Create and hWnd will be null at that point.

I think it should work in the list's OnCreate, though. Post some code to see how you are doing it...
