hi,

any idea on sniffing remote machine...my exaction scenario is like this:

i have machines A,B,C.and from machine A, i want to just monitor all the traffic that is going from machine B to machine C.

I have tried etheral...etc but all these are collecting the traffic that is coming and going out of a NIC card where etheral is running. but my problem is to sniff the remote machine...

You wanna put the NIC that ethereal runs on in promiscuous mode, this will capture most of the traffic on the LAN.

This is problem is related to switched network.From a single machine i want to monitor the whole network traffic.
If i have machine A and if i run ethereal it shows only the traffic that machine A's NIC is receiving or sending from/to LAN. But i want to monitor the incoming or outgoing traffic of a remote NIC also.

you would need to replace the switch with a hub. The whole point of a switch is that you only get the data intended for your machine. Failing that install some kind of logging software on the other machine. If you want to monitor data at the switch you may be able to use OpenView or equivalent if your hardware supports it.

thanks for the reply russ..

but i have no idea how openview may help me in doing this...baiscally, i want to monitor all the packets that are going in a swithced network..i found 2 options..1.port mirroring 2. arp spoofing...are there any other approaches to sniff all the machines from a single machine?

i need it appear in the Task Bar always.actuly the problem gets when it doesn't appear on the task bar where need to use ALT+TAB to access it... Smile | :)

If you want a dialog to appear in the task bar, it can't have a parent window.

If you want to access the dialog when it has a parent, just alt+tab to the parent.

I want to develop a video player of my own with my own specifications but i am not sure from where should I start for, I am totally new to window programming. Can you please direct me that what can I use for this purpose?

That is quite an undertaking for someone that is new to windows programming. I would first start by learning about how video files are stored and retrieved. I'd also find out how to convert from the various file formats to something that can be rendered on the screen. I'd find out how to get the sound our of the file and send that to the sound card. I'd find out how to syncronise the sound with the video.

In fact, of all the things that this project requires probably the only thing I wouldn't have to learn is how to put the buttons on the form.... And I've been writing software for 24 years. It looks like you have a lot to learn.

Upcoming events:
* Glasgow: Mock Objects, SQL Server CLR Integration, Reporting Services, db4o, Dependency Injection with Spring ...
* Reading: Developer Day 5

Ready to Give up - Your help will be much appreciated.

If you mean you want to drag a media player control onto your form and 'skin' it, that seems easy enough. If you want to write a whole new program to play video files, then that's just not a suitable beginner project, on any level. It's also a waste of time IMO.

If it is aready built in to MSN Messenger why would you need to write code for it? Confused | :confused:

Bound ComboBox problem

kbalias21-Jun-07 21:21

Hi
I am using Visual Studio 2005 and C# for a Windows application. I have a usercontrol with multiple input controls, including 3 Comboboxes. I am binding DataTables to my ComboBoxes and I am also using AutoCompleteStringCollections as the AutoCompleteCustomSources in these ComboBoxes. I am using the following general method to set up the ComboBoxes:

private void PopulateComboSmart(ComboBox combo, DataTable table, string displayMember, string valueMember, AutoCompleteStringCollection dataCollection)<br />
{<br />
    combo.DataSource = table;<br />
    combo.DisplayMember = displayMember;<br />
    combo.ValueMember = valueMember;<br />
<br />
    combo.AutoCompleteCustomSource = dataCollection;<br />
    combo.AutoCompleteMode = AutoCompleteMode.SuggestAppend;<br />
    combo.AutoCompleteSource = System.Windows.Forms.AutoCompleteSource.CustomSource;<br />
<br />
    combo.SelectedItem = null;<br />
}

On the form I have a large number of these UserControls for user input and the user can also add more or delete some of them. When the form loads all is ok and the selected items in the various ComboBoxes are null and nothing is displayed (I am doing this so that the user has to explicitly select an item in the ComboBoxes and not inadvertently use the first item in the ComboBox). However when the form refreshes the ComboBoxes that have not been selected yet all display the first item in the ComboBox even though the selected index have not changed.

Is there a way to force it to not display the first item until explicitly selected?

Thanks.

Kobus
