Hi All,
I have an application in which i need to know when the user has plugged in or plugged out the ethernet cable to the system.
I have the adapter information within my application.
I tried using the device change notification with Registering the notification giving the guid for lan class. But this helps only when i either enable or disable the land adapter from my device manager.
Please help or provide pointers to some link.
Thanks in advance.

Does this help any? What about the ISensNetwork interface?

Hi all,
The Id IID_IConverterSession appears as unresolved external symbol how did that happen? Plus can anyone help me get my code right i am a super beginner at this.
Many thanks,
Jj
HRESULT hResult;

if (hResult !=S_OK){
throw(HResultException("MapiInit ResolveMsg",0));
}

Maybe you need to import a lib file.

So why in the world would you be starting off with a COM project? If you don't yet have the basics mastered, why make matters worse with COM, and MAPI atop that?

Hi
In my VC++ Socket programme I can connect to another system and transfer the data between them, the system are connected through LAN.
I want to know how can communicate with another system through Internet by socket programme(with out LAN ,through Internet).
(Like Server running in anywhere and client was Running anywhere they are connect through internet by Socket programme)
Regards

It should work exactly the same - your connect() call can specify 'www.codeproject.com' just as easily as it can specify '192.168.0.5' - if this does not seem to work, perhaps a small code sample showing how you try to connect to the remote server would help us see where the problem lies?

You shouldn't be facing any problem to connect to the Internet Server. But to Retrive or to send the Data on the Internet server you need to follow the Http protocol. that mean you first need to send the Http Header. That depends on the metod you are using. There are two Methods in Http, Http POST and Http GET.
Try to find out the header for that and Send it Before you send the data.
The Sample Header is as Follow. Try it if it works
"POST / HTTP/1.0\n
Accept: image/gif, image/x-xbitmap, */*\n
Accept-Language: en-us\n
Accept-Encoding: gzip, deflate\n
User-Agent: Mozilla/4.0\n
Host: WWW.CODEPROJECT.COM\n
Content-Type: application/x-www-form-urlencoded"

This time is measured in the number of seconds elapsed since 00:00:00 January 1, 1970, Universal Coordinated Time.
TimeGenerated = 1183355639
So how do I get it to the correct time??
Many thanks

I'm guessing you have it as a time_t? Use localtime() to convert to a tm struct which has members for hour seconds etc
|
|
|
|

Hi,
I'm making use of the following:
typedef struct _EVENTLOGRECORD {
...
DWORD TimeGenerated;
...
}
Thus the following won't work
TimeGenerated = pevlr->TimeGenerated;
newtime = localtime( TimeGenerated );
How can I convert it?
Many thanks in advance

what are the functions you are using to retrieve this number?

ReadEventLog() and then I'm making use of the struct EVENTLOGRECORD *pevlr; (pevlr->TimeGenerated;)

In VC++ I use:
void CMyDoc::FormatTime ()
{ CTime time = CTime::GetCurrentTime();
CString szStartTime = time.Format ( "%A, %d.%B.%Y, %H:%M:%S" );
//Do whatever you want
return;
}
On the other hand... you can always make the conversion by yourself.
60 * 60 * 24 * 365 = 31536000 // Seconds in a year
60 * 60 * 24 = 86400 // Seconds in a day
3600 // Seconds in an hour
...............
TimeGenerated = 1183355639
int years = TimeGenerated / 31536000;
int rest1 = TimeGenerated % 31536000;
int day = rest1 / 86400;
int rest2 = rest1 % 86400;
and so on...
To get month, day of the week and other things you can work in a similar way.
I hope it helps
Greetings.

Did you include the header file of CList ?
|
|
|
|
|
Did you include afxtempl.h?
|
|
|
|
|
as the others said, the header file for CList is not included
if you want to have an example of working with templates of collections take a look to the Smart Lists in:

Hi all,
I'm using the following function to read the Source of the System events. I'm trying to check if the source name is equal to "Windows Agent" or if the EventId is equal to 21. Which would indicate that the computer needs a restart. But I don't get any result and there is without a doubt such an entry in the event log.
oid DisplayEntries( )
{
HANDLE h;
EVENTLOGRECORD *pevlr;
BYTE bBuffer[BUFFER_SIZE];
DWORD dwRead, dwNeeded, cRecords, dwThisRecord;
int counter=0;
h = OpenEventLog( NULL,
"System");
if (h == NULL)
{
Form1->msg = Form1->msg.sprintf("Could not open the Application event log.");
Form1->Memo2->Lines->Add(Form1->msg);
}
pevlr = (EVENTLOGRECORD *) &bBuffer;
GetOldestEventLogRecord(h, &dwThisRecord);
while (ReadEventLog(h,
EVENTLOG_FORWARDS_READ |
EVENTLOG_SEQUENTIAL_READ,
0,
pevlr,
BUFFER_SIZE,
&dwRead,
&dwNeeded))
{
while (dwRead > 0)
{
printf("%02d Event ID: 0x%08X ",
dwThisRecord++, pevlr->EventID);
printf("EventType: %d Source: %s\n",
pevlr->EventType, (LPSTR) ((LPBYTE) pevlr +
sizeof(EVENTLOGRECORD)));
if ((LPSTR)((LPBYTE) pevlr + sizeof(EVENTLOGRECORD))=="Windows Agent")
{
MessageBox(NULL, "FOUND", "INFO",MB_OK);
}
dwRead -= pevlr->Length;
pevlr = (EVENTLOGRECORD *)
((LPBYTE) pevlr + pevlr->Length);
}
pevlr = (EVENTLOGRECORD *) &bBuffer;
}
CloseEventLog(h);
}
Many Thanks in advance

The first error lies in the following line
if ((LPSTR)((LPBYTE) pevlr + sizeof(EVENTLOGRECORD))=="Windows Agent")
What you are performing is a pointer comparison with a static string. This is only going to work in two ways
if the expression (LPSTR)((LPBYTE) pevlr + sizeof(EVENTLOGRECORD)) is used to initialise a string class like std::string or CString etc
a more straight forward way is to use a string compariosn function eg strcmp or its wide equivalent if you have a Unicode project.
i.e.
if(strcmnp((LPSTR)((LPBYTE) pevlr + sizeof(EVENTLOGRECORD)),"Windows Agent") == 0)
The other problem you might face is user priveledge as access to a system resource like the event logs may be restricted if you are not an Admin user.
