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?

No it is not opened, it threw an exception.

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.
Why is common sense not common?

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.

I am working with ActiveX Controls for a 3D App. The interface dll's come in 2 flavors,
a lite version that works without a license and a full version. Both dll's include the same
types just that some are disabled in the lite version. I would like to be able to reference
either dll for the same classes and methods depending on whether or not the user has a license
available. I have tried overriding a using alias and using directives with abstracts to get it to work but
have not been successful. Is there any way to do this without duplicating the Classes and methods
with their respective usings?
Thanks,
|

I know the how it would be done in .NET dll file, but not in activeX.
Maybe atribute dllimport would help. Here is some reference:
Using Unmanaged code and assembler in C#[^]
I would done in a way that there would be one ActiveX dll, and that dll would check the licence and would return to the application if it is using license or not.
|

Thanks Saksida,
The dll's are managed.
I had started looking into loading the dll's as assemblies but was not sure
how to make it work, If I have to reference each type individually then I think
it would be less work to just copy the Classes for each case.
|
|
|
|
|
If it is managed then look into Activator.CreateInstance()
This is a good article for using Activator: Plug-ins in C#[^]
Also i got this message in the email:
The dll's are managed, they are VB6 originally I believe.
VB6 application doesn't use .Net Framework. This is the VB version prior .NET framework versions

Sorry, should have typed VB.net (or at least explained my edit)
the Activator.CreateInstance() looks interesting, thanks for the heads up.

Hi
I need to create a program that searches the internet for all Ecommerce websites in South Africa.
So i made a web crawler to search through web pages by using there text to search for keywords on ecommerce and location.
Unfortunatley when using HttpRequest and HttpResponse on a google search, its retieves all the html but not the google search links.
Why is this? Is there a better way to do this? Any input would really help.
Thank you for your time.
Kindly Rian

Why is this?
It might be inserted dynamic, arriving over the internet some seconds after you have saved the HTML-page that contains the results. It could also be a means of protecting their search-results. To check which one it is, you'd have to save a second or two later.
You might be interested in a Google Custom Search Engine[^]. Not only does it crawl where you want, it also delivers its results as XML

Thanks Troll, i added a 500ms delay and it worked!
Ur the bomb!
Gonna check out that google custom search thing.
Thx for your help
(always helps to ask the smart guys)
