I figured it out, I stepped through the code and learned that the static Object.Equals(object a, object b) called in the operator overload actually makes a call to the virtual instance-level Equals(object obj), so the static ReferenceEquals has to be used to test for instance equality. Though by default the static Object.Equals(object a, object b) will do the same thing as the static ReferenceEquals, unless you override the instance-level Equals method, because the default instance-level Equals method tests for instance equality.

Wow, you have a Surface? 
Seriously, you are likely to get a quicker answer if you google/bing/yahoo for c# video capture.

Really? I had no idea! Thanks for the HUGE tip!
Maybe, just maybe I was being sarcastic as the OP left no information allowing others to help him, how he wanted to capture a video, using his own software or interfacing with third party software, what format, anything of the sort! Way to go!

Yes indeed, the question is very clear...

Yes, extremely clear. I'm sure he is fast on his way to 'record video desktop'.

You mean "stop being a fool"?

Do I hear sarcasm? Lol, however the answer to the question willn't come. Maybe we could stop spamming all around here.

Tell me why? Why should I be a "tool"?

You're a tool because all you're doing is attempting to aggravate me while spamming the boards.
You're a tool.

I'm spamming the boards? Look around! It's you who said I' a tool, it's you who said "use printscreen" while that's totally wrong... You're such a ****** ***

hi there,
i have recently posted a Question asking how to send and recieve raw ethernet packets (bits on the wire) to the dialup (or any kind of modem) Modem's Connection, i have searched a lot and found and downloaded a Library Called SharpPcap (managed code for WinPcap) that can exactly do what i want, but only over Lan Connection and when i was trying to send packets over Dialup connection it fails,
someone answers me and tell me to send packets using SerialPort class, since Modems are connected to the computer using serial ports(like COM1 or COM2)
now suppose that my dial up modem is connected to the internet and is at port COM1, i'll wrote something like this:
<br />
SerialPort sp = new SerialPort("COM1",9600);<br />
sp.DtrEnable = true;<br />
sp.DataReceived += new SerialDataReceivedEventHandler(sp_DataReceived);<br />
sp.Open();
sp.Write(....My Packet);<br />
as i specify it throws me an exception, since this port is Opened now and is owned by a process, and as long as ports(such as COM1) can only be used by one and only one process, i can not do any thing...
is there another way or something else, i've searched for 2 or more weeks ...

AT COMMAND LIST[^]
Have you considered to send AT command to modum to dial specific number
|
|
|
|
|
i didn't ask what to send to modem, i have asked how to communicate when the port is opened by another process and i want to open() it and send AT Commands!??
|
|
|
|
|
I Doubt it is even possible. This is probably driver related

What exception is it throwing?
spiritboy wrote: since this port is Opened now
No it is not opened, it threw an exception.
spiritboy wrote: and is owned by a process
Do you mean to say the some other program has the serial port open already and you want to use both of your programs for the same serial port at the same time? I am not so sure that you can share a serial port.

the Exception is IOExceptio and telling : "The process cannot access the port 'COM1' because it is being used by another process."
the reason is that my modem is already connected to the internet (so is under used by another process), and i want to send packets to it.
when the modem is not connected i can successfully Open the port.
to make it more clear, i do not have another program that opened this port!

What you are saying contradicts yourself. If the port is opened by another process then by definition something else opened the port. You cannot open an already opened port. If as you say your program has the port open, why don't you just start sending packets to it?
In other words, you are trying to open a port you already have open when there is no need to open it again.

I am sorry for this,
again! i said my modem is connected to the internet!!! when it is connected to internet i can not Open its port since it is connected to the internet, i am not trying to open port for second time! all i need is to send packets over dialup.
more explanation: when i go to StartMenu\Connect to\My dial up Connection\Dial then i can not Open the modem Port. i do not have a second program running and using the port. the process that is using the port is one of windows processes.
i did not contradict myself, i said:
while modem is connected (by StartMenu\Connect to\My dial up Connection\Dial) i want to send packets!
the way i found is to use serial port, but while my modem is connected i cannot Open its port in my program unless , myself in the program dial and connect to the ISP.(not using StartMenu\Connect to\My dial up Connection\Dial)

Sorry, whether you realize it or not, you are contradicting yourself.
You say:
spiritboy wrote: i am not trying to open port for second time
and then:
spiritboy wrote: the process that is using the port is one of windows processes.
So slowly. The reason that you cannot open the serial port the second time is because you already have it open with another program! That is what the other process is! If you want to open the serial port again, you have to shut down the other program, process or alien intelligence that is using it first. Whether you started the process or Windows started the process does not matter at all. You can only have the serial port open by one process at a time.
