You can check GeoIP. They provide some API's for finding country code from IP address.

Hehehe - grins TCP. Yup TCP doesn't have a mechanism to detect it automatically..and it's because any network would have frequent "negligible" disturbances that TCP would not take it as a "disconnect". The only way I knew was to keep a routine to check clients PULSEs .
Server->"Are you there?"
Client0->"Yup".
Client1->"Yup".
Client2->... .
clientList[2].remove(); 
OK,. what country just started work for the day ? The ASP.NET forum is flooded with retarded questions. -Christian Graus

the question which i have asked is indirectly abt the pinging
in this scenario i can do one thing
send some bytes to client and in reply to that recive some bytes from client ............
but what i really wanna do is that once a message is send from the server it must be in a state to know weather the client system is in the network or not .........
dude if u have any idea abt this then let me know

Yes, that's possible. Check for IPPROTO_ICMP.
But I would only suggest a mechanism where the client *replies* to our pulse-ping. Because imagine a case, the network is out and in few seconds it's up again. Now you send your ICMP query this would say that the client is still up. But it's a reincarnated client, it doesn't hold up the old connection. So your client list would go meaningless. So make a seperate thread that keeps pinging for clients pulses and mainting the clients.

I have a snippet of code that is similar of what you search. Try to fit it to your request.
See how it works at: <a href="http://yoni.minicircuits.com/MixerResult.aspx">http://yoni.minicircuits.com/MixerResult.aspx</a>[<a href="http://yoni.minicircuits.com/MixerResult.aspx" target="_blank" title="New Window">^</a>]
Mouse over the case style column.
<u>The code:</u>---------
<ItemTemplate>
<a class="thumbnail" href='<%# Eval("CaseStyleURL") %>' ><%# Eval("CaseStyle") %>
<span>
<img style="border-width: 0;padding: 2px;"src="CaseStyle/<%# GetCaseStylePicture(Eval("CaseStyle")) %>.jpg" />
</span></a>
</ItemTemplate>
<u>Style sheet:</u>
.thumbnail{
position: relative;
z-index: 0;
}
.thumbnail:hover{
background-color: transparent;
z-index: 50;
text-align: center;
text-decoration: none;
}
.thumbnail span{ /*CSS for image*/
position: absolute;background-color: #F0F8FF;padding: 5px;left: -1000px; border: 1px dashed gray;visibility: hidden;color: black;
}
.thumbnail span img{ /*CSS for image*/
border-width: 0;
padding: 2px;
width:70px;
height:70px;
}
.thumbnail:hover span{ /*CSS for image on hover*/
visibility: visible;
top: -70px;
left: -90px; /*position where enlarged image should offset horizontally */
}

Hi,
I am developing a web application which requires the following to happen.
Go to another web site. The web site informs me of schedule no. x. After clicking on a hyperlink, I am transported to the page containing html file names in the ftp directory.
I pick up the respective file whose file name bears the schedule number X. I download the html file in my local filesystem. The data represented by the html file is in columnar format. I need to pick up data in the last column of the html file.
Now what I need is
a)Is there any method to monitor the change in schedule no from x to y (from schedule 1 to 2 and so on). In other words polling the other website for change in its specific piece of data
b)Pardon my asking but how will I fetch the columns from the html file. I have a feeling this is going to be real dirty job of extracting information from the html file
Any pointers to dazzle  baffle  me.
Regards

Probably best done through a webservice.

So we have GridView inside of it are templates for example label and text box for edit mode which are connected with some db.So the problem is appear when i try to update that data exactly in updating event.After pressing update button in quick watch i see that it is give me old value not what i had change ready!!!For example in label value is 1 and when you press button edit in text box is 1 too but my goal is to be changed to 2 so in text box value is changed to 2 but after pressing of bot ton the value which is extract is 1???Pleas cloud you tell me some body why.Unfortunately the at the moment i am not in-front of my pc but let try the code.
string name;
name=((TextBox)(gvMain.Rows[e.EditIndex].Cells[1].Control[1])).Text;
And result is 1;
Please tell me why
Now the project on which i work it use net.3.5 can you explain me if there is some changes and why if i catch the text box the value is old one not the value which i already type on it.
Thanks in advance.
when i want to read something good just seat and type it

Is it possible to get all the Unchecked nodes of TreeView control as a TreeNodeCollection the same way TreeView.CheckedNodes does.

I use this function for Encypt my strings,but I want to know how I can Decrypt string.
<br />
public string Md5AddSecret(string strChange)<br />
{<br />
byte[] pass = Encoding.UTF8.GetBytes(strChange);<br />
<br />
MD5 md5 = new MD5CryptoServiceProvider();<br />
string strPassword = Encoding.UTF8.GetString(md5.ComputeHash(pass));<br />
return strPassword;<br />
}<br />
<br />
protected void bntDisp_Click(object sender, EventArgs e)<br />
{<br />
<br />
try<br />
{<br />
TxtResult.Text = Md5AddSecret(TxtPassword.Text);<br />
}<br />
finally<br />
{<br />
Response.Redirect("UrPage.aspx");<br />
}<br />
}
Thanks in Advance...![Rose | [Rose]](https://codeproject.freetls.fastly.net/script/Forums/Images/rose.gif)

This function may help you to decrypt string.
Public Function Decrypt(ByRef Data As String) As String<br />
Dim decData() As Byte = Convert.FromBase64String(Data)<br />
Dim decStr As String = ASCIIEncoding.ASCII.GetString(decData)<br />
Decrypt = decStr<br />
End Function
use SHA1 Algorithm for Encryption.
Public Function Encrypt(ByRef Data As String) As String<br />
Dim sha As New SHA1Managed<br />
Convert.ToBase64String(sha.ComputeHash(Encoding.ASCII.GetBytes(Data)))<br />
Dim encData() As Byte = ASCIIEncoding.ASCII.GetBytes(Data)<br />
Dim encStr As String = Convert.ToBase64String(encData)<br />
Encrypt = encStr<br />
End Function
Regards.

MD5 is not an encryption algorithm, its a hashing algorithm. Hashes don't "decrypt" - they are a summary (digest) of the information, a checksum. They are lossy. Have a look on wikipedia about the difference.
You probably want to look at the RSA CryptoServiceProvider.

Answer as above, MD5 cant be Decrypted. because it is a Digest algorithm.
if u want to encrypt and decrypt message, DES and AES cryptography algorithm will be your selection.

You cannot decrypt the hash. Hashes are one-way.
