Interesting...
How you discover that that's the function?
By reading all the 10000 pages in strict alphabetical order?

It doesn't take much effort to type into that little box they call "Search" and then click the button called "go"...

No, just the ones up to the function that you are interested in. All the pages after that do not need to be read, unless you just wanted to.

Hi, here is another option

BOOL IsDirectory(TCHAR *szPath)
{
	BOOL bRet = FALSE;
	DWORD dwResult = GetFileAttributes(szPath);
	if(dwResult != 0xffffffff  &&  (dwResult & FILE_ATTRIBUTE_DIRECTORY))
	{
		bRet = TRUE;
	}
	return bRet;
}

Best Wishes,

What does "validate" mean? Are you wanting to check if it has invalid characters, or whether it exists?

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.

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? Roll eyes | :rolleyes:

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 ); /* Convert to local time. */

How can I convert it?

Many thanks in advance

long_time = TimeGenerated;
newtime = localtime( &long_time ); /* Convert to local time. */

Never mind .... Unsure | :~

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

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
