Nope, it is pretty good (Nish rocks): thank you for signaling.

hello guys..I read somewhere that callback function works better than the WM_TIMER in vc6. So I tried following code but it does't work. whats wrong with it?
BOOL CTimers_CallbackFuncDlg::OnInitDialog()
{
..........
..........
SetTimer(ID_CLOCK_TIMER,1000,(CALLBACK)&Timer1);
..........
}
void CALLBACK CTimers_CallbackFuncDlg::Timer1()
{
CTime curTime = curTime.GetCurrentTime();
m_sTime.Format("%d:%d:%d",curTime.GetHour(),curTime.GetMinute(),curTime.GetSecond());
UpdateData(FALSE);
}
a syntax error is given saying error C2059: syntax error : '__stdcall'

This could simply be:
SetTimer(ID_CLOCK_TIMER, 1000, Timer1); You could also pass NULL as the last argument and handle the WM_TIMER messages.

What do you mean by "callback works better"?
You need to find out the exact reason why that statement was made and if it applies to you.
Anyway, I think the error is because the callback signature is not what is expected.
Here is an excerpt from MSDN -
The lpfnTimer callback function need not be named TimerProc, but it must be defined as follows:
void CALLBACK EXPORT TimerProc(
HWND hWnd, // handle of CWnd that called SetTimer
UINT nMsg, // WM_TIMER
UINT nIDEvent // timer identification
DWORD dwTime // system time
);

This is the term that im quoting from a text book. The auther used exactly this term for the procedure.

That is not good enough.
If the author has not explained why it is so, you could probably send him/her an email asking for clarification.

That's vague and without foundations, I think can't be the rationale for your choice. Probably the WM_TIMER message would fit your needs as well.

As David already suggested that cannot be a standard (a instance) method of the class, it must be either a static method or, simply, a function.

Since I already told here..I read it somewhere. According to the author;
Timers are placed into the application queue (only if application is idle). If the application is not idle and has been busy (due to which several timer event messages can be missed by the app), windows places only one timer event in the application queue. Hence Windows does not sends all the timer events to the application when it was busy (and no matter how many timer messages have been missed, it still places only one timer event in the queue).
This was the reason (which from the feedback so far, I think is wrong) I was trying to write a function.

As far as I know, the callback isn't called in the context of another thread, hence, if your main thread is busy, then it wouldn't be called either.

The callback is called on the thread that set the timer. It's called from it's message pump (if it hasn't got one the mechanism doesn't work).

WM_TIMER messages are not accumulated.
If you think about it you really don't need this.
If you miss a time interval, you just wait for the next.

Firstly, drop the (CALLBACK) cast, it won't help. In fact such "optimistic casting" (ignoring what something is and just pretending it's what it should be) often just makes things worse by turning compile-time errors into runtime errors. Only use casts when you know exactly what you're doing.
In your case the problem is that the callback can't be a non-static member function.

I can't see why. In your case the exact opposite is true as not using a callback means MFC does all the non-member-function to member-function thunking for you.

Hi there,
I've an application which uses MAPI for sending mails.
It was all working well with Outlook 2007 on Win XP.
But when I work on Outlook 2003, with the same application, it is throwing an error - 2 (MAPI_E_FAILURE)when making a call to MAPISendMail() API.
I used the sample application to test whether there is any issue with Outlook 2003, from the following link: Programmatically adding attachments to emails[^]
but it seems to be working well. Only when I try to send mail from my old app, it always returns with the error 2.
I've googled and tried almost all possible steps, but the issue still exist.
ULONG nError = m_lpfnMAPISendMail(0, 0, &mapiMessage, MAPI_LOGON_UI|MAPI_DIALOG , 0);
please advise on the resolution.
Thanks in advance.
regards,
Rajesh

Hey,
I need to earn some points in my IT class and thought about writing a tool that would tell you what runs on a specific port, in this case port 80.
Now it would most likely be a webserver, finding that out is no problem by checking for specific strings such as "" etc..
My problem is though, I would like to know what kinda Webserver runs on that port.
How would I do that?
Unfortunately the replies are not really formated, so its really hard to filter it out.
Example:
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

a:link { color: #0000CC; }
p, address {margin-left: 3em;}
span {font-size: smaller;}
--></style>
</head>
<body>
<h1>Bad request!</h1>

is what I recv() when i send() to 109.70.146.167 on port 80.
That does not actually help me though, as the banner is not always the last message..
Sometimes the banner is not even in it at all..
65.39.148.34 on port 80

I did some google digging and found out about certain tools that would grab the banner such as Acunetix Vulnerability Scanner, atleast for http server it grabs EVERY banner.
Any suggestions?

I don't think you can do this as the response that you get from any web server depends entirely on that server. There is no standard format that will give you a consistent piece of information; just surf a few different sites to see.
Just say 'NO' to evaluated arguments for diadic functions! Ash

Yea, I just found that out too, so I digged some more and found out about some webscanner or whatever they are called.
How do those tools get literally every(for webservers atleast) banner though?

|
|
|

No idea, I'm a simple C++ programmer.
What exactly do you mean by 'banner', is it some special piece of HTML?

Banner is like a name that identifies the service that runs on the port.
Iam just look for a way to identify what service/program runs on a port.
Example:
For an ftp it's the first reply:
220-FileZilla Server version 0.9.34 beta
Iam looking for something similiar that works for webservers.

Well known port numbers are as defined here[^]. Also if you look here[^] you will see that there is no HTML tag that describes the information you are looking for.

Check the HTTP response headers. Some web servers include a Server header in every response, e.g. Server: Apache/1.2.3. Practically, you take a HTTP client class, make a dummy request and evaluate the response headers. It's a simple way to identify the web server software running on that port, it is not reliable as you can often configure or omit this information on the server side.
Happy coding!
