how can i get ipaddress into database?

String strHostName;
//= new String("");
if (args.Length == 0)
{
// Getting Ip address of local machine...
// First get the host name of local machine.
strHostName = Dns.GetHostName();
//MessageBox.Show(strHostName);
}
else
{
strHostName = args[0];
}

// Then using host name, get the IP address list..
IPHostEntry ipEntry = Dns.GetHostByName(strHostName);
IPAddress[] addr = ipEntry.AddressList;
for (int i = 0; i < addr.Length; i++)
{
strip = addr[i].ToString();
//MessageBox.Show(strip);
}

Is it proper?It is stored in 'strip' variable, which i have to call later in a function. can u get it?
How shu i declare these : args,Dns,args[0],IPHostEntry,IPAddress[] ?
thanx

Perhaps this should help you...

public string strHostName="";<br />
public string [] args=null;<br />
public IPHostEntry ipEntry =null;<br />
IPAddress[] addr=null;<br />
.<br />
.<br />
.<br />
.<br />
.<br />
.<br />
if (args.Length == 0)<br />
{<br />
// Getting Ip address of local machine...<br />
// First get the host name of local machine.<br />
strHostName = Dns.GetHostName();<br />
//MessageBox.Show(strHostName);<br />
}<br />
else<br />
{<br />
strHostName = args[0];<br />
}<br />
<br />
// Then using host name, get the IP address list..<br />
ipEntry = Dns.GetHostByName(strHostName);<br />
addr = ipEntry.AddressList;<br />
for (int i = 0; i < addr.Length; i++)<br />
{<br />
strip = addr[i].ToString();<br />
//MessageBox.Show(strip);<br />
}

I have a form with a number of user controls on, however the form seems to keep corrupting. I don’t have the problem with any forms that don’t have user controls, and another dev here has the same problems on another app (different user controls as well).

This is the error that I get when I try to load the form in the designer

Any suggestions

I am using VS 2005

Hello,

The designer calls the Constructor and also the setters of properties if they are set, from your usercontrol.
In your case you whant to access an object wich is not created (instanziated) yet, therefore you get this null ref Exception.

You first have to find the point in the usercontrol where the exception is thrown:

You could start a second instance of your project and then connect at youre first instance.
After that you should set a breakpoint in your controls constructor, and then open the form (designer) in the first project.

Or go threw the code and look for unsafe code (like access without a != null if statement).

Once you find your problem please don't use the "DesignMode" property (like some programers would recommend) as a workaround, make it run by changing maybe the design or use an if statement.

Hope that helps!

All the best,

Martin

You could only find that out with debugging!

There are some interesting statements in this thread, which could help you!

I would suggest that you look at using Process.Start to run osql.exe.

You can run just about any SQL through a SqlCommand. Just read the file in to a string and dump the string into the SqlCommand.

NOTE: GO is not SQL. It is a preprocessor command to Query Analyzer to tell it to split the file into batches. If your file has GOs in it, you need to split it up and send them as separate SqlCommands.

<code>ResultForm.richTextBox1.Text += "Return Result # " + (beginResultPage + i + 1).ToString() + "\r";
ResultForm.richTextBox1.Text += gresult.resultElements[i].title + "\r";
ResultForm.richTextBox1.Text += gresult.resultElements[i].snippet + "\r";
ResultForm.richTextBox1.Text += gresult.resultElements[i].URL + "\r\r";
ResultForm.richTextBox1.Text = ResultForm.richTextBox1.Text.Replace("", "");
ResultForm.richTextBox1.Text = ResultForm.richTextBox1.Text.Replace("", "");
ResultForm.richTextBox1.Text = ResultForm.richTextBox1.Text.Replace(" ", " ");</code>

Hi
reading from the codes above, i want to bold some of the results that is recieved through the richTextBox control in the form.

For eg, if i want to make bold the title that is produced using this line of code,
ResultForm.richTextBox1.Text += gresult.resultElements[i].title + "\r";

What do i need to add in to ensure that the results is in bold?
