Hello everyone,

I want to monitor Http traffic from my local computer (Windows Server 2003) -- not always using IE -- to some specific web site.

I am interested in the headers/bodies in request/response. Any tool to use? Or code samples so that I can easily write one?

thanks in advance,
George

search in codeproject for "packet capture". There are some articles about that.

Thanks stancrm,

I think WireShark tool is good enough for me. I do not need programming, using existing tool is fine.

George

For developers, there's a library called WinPcap[^] (and certainly some .NET wrappers for it) which you can use.

As a standalone tool, the best I know of is WIreshark[^].

Thanks Simon,

Fiddle is good, but can only monitor IE http traffic. I want to monitor some specific application's traffic. Any comments? Could Fiddle do this or any other recommendations for this goal?

George

Fiddler can monitor non IE traffic. Think you have to set your app to send it's data through a specific proxy address which fiddler will monitor and forward on.

There's a bunch of stuff in the help docs on their website. Look for the bits on configuring fiddler for .net apps.

(Or try the other suggestions. Maybe wireshark does what you're after, I've never used it so I'm not sure.)

Thanks Simon,

Which API could be used to send Http traffic through a proxy?

regards,
George

Re: monitor Http traffic

Simon P Stevens3-Aug-08 21:44

Well whatever API you are using to send data already should be configurable to work via a proxy. Check the docs for the particular API you are using. I think the standard .net http stuff uses the WinINet API underneath which I believe fiddler will just pick up automatically anyway without any config.

There's an MSDN article here on proxy configuration in .net: http://msdn.microsoft.com/en-us/magazine/cc300743.aspx[^]

There's a fiddler FAQ here on how to configure different types of app: http://www.fiddlertool.com/Fiddler/help/hookup.asp[^]

(Or you can configure fiddler as a reverse proxy http://www.fiddlertool.com/Fiddler/help/reverseproxy.asp[^])

Oh, and there's a whole article on fiddler debugging on MSDN here: http://msdn.microsoft.com/en-us/library/bb250446.aspx[^]

There's loads of info on this. Just Google it.

Great Simon!

Just want to confirm with you from what I learned, we can use WebRequest.Proxy to explicitly set the proxy to be used for each web request?

You're going to get it as a stream from DirectX, same as the video, if the webcam has an audio stream.

CodePrimitiveExpression Class

Hi All,

Regarding this C# statement:

CodePrimitiveExpression stringPrimitive = new CodePrimitiveExpression("Test String");
System.Console.WriteLine(stringPrimitive);

the output will be "Test String", is there anyway that i can get rid of the double quotes, so the output can only be:

Test String
instead of
"Test String"

Many Thanks

Andie

Did you actually try it?

This code:

CodePrimitiveExpression stringPrimitive = new CodePrimitiveExpression("Test String");
System.Console.WriteLine(stringPrimitive);

Outputs this:

System.CodeDom.CodePrimitiveExpression

This code:

CodePrimitiveExpression stringPrimitive = new CodePrimitiveExpression("Test String");
System.Console.WriteLine(stringPrimitive.Value);

Outputs this:

Test String

No quotes, see. Cool | :cool:

Is that what you want?

center picturebox inside panel

hi,
(this is only a design issue).

In a particular form i load pictures to a picturebox from a Database
(or when uploading with browse).
That picturebox is inside a panel.
The picturebox as the sizemode propriety set to AUTOSIZE (remember this).
What i want is to center the picturebox inside the panel!!!
It looks simply right? Wink | ;)

I got width and height of both panel and picturebox and did the math,
but ... because it is AUTOSIZE, couldn´t center it because i got width and height of the picture original size(the one i load in picturebox)!!!
I can´t get the width and height of the picturebox when AUTOSIZED in order to center it

Want is the propriety to get width and height of AUTOSIZED pictures??? Confused | :confused:

Thanks

Re: center picturebox inside panel

Christian Graus31-Jul-08 13:43

There is none. Autosized means the control is redrawing your pic at the size it wants to.

To get that sort of control, you should draw the pic yourself.

Can't you just dock the picture box in the panel, and let the picture box center the image?

Despite everything, the person most likely to be fooling you next is yourself.
