Trust me, it's a string.

I am tryng to serialize the IP's Server Addresses in my Lan using objects IPHostEntry for getting better the communications with them, later I need that the machines which are going to connect with such Server Serialize and Deserialize the Server's List, but when I try to serialize, both in binary or XML, I receive an error telling me that such object IPHostEntry is not marked as Serializable.

Any suggestion for avoiding this problem

Note: I Create a Dictionary<string, iphostentry=""> containing the name and IP data of every Server and such is the object which I want to Serialize, if the key and value are both strings there is no problem, but when I change to Type IPHOstEntry it does not work.

0) UPDATE INTO -- nope
1) colErrByUserID = '" + LoginForm.gb_strUserID + "' "; -- very bad idea

Thanks for that! Sleepy | :zzz:

Very useful, not!

So what you are really saying is you don't know...

No, I'm just not going to spoon-feed you. You'll find very few people here who will.

Rich,

Just I want to repeat the node in aloop by incrementing id.

Richard MacCutchan22-Sep-09 10:14

I don't understand what your problem is. What code are you using to create the original XML, and what code have you tried to create the repeat items?

kurangu22-Sep-09 10:22

22-Sep-09 10:22

Rich,

In c#.Original xml is a string which I get like below

<details>
<detail id="1" name="x"/>
</details>

I want to take that xml string and to repeat the nodes

foreach xml nodes

<details>
<detail id="1" name="x"/>
<detail id="2" name="x"/>
<detail id="3" name="x/>
</details>

id=2 and id=3 is repeated.want to do it in C#

That can be easly done using XmlDocument.
You know that class? Have you already tried something or you want us to give all the code to you (that you won't get here, I'm afraid)?

Where do you get this from, a const string, XmlReader, TextReader?

I ask again, what code have you tried; please help us to understand better what you are actually doing in your code?

HI,

It's a constant string.

string a =
"<SecDetails><Security PrimarySecID=\"abcd\" Price=\"12\"/></SecDetails>";

XmlDocument originalXml = new XmlDocument();
originalXml.LoadXml(a);

XmlNodeList nodelist = originalXml.SelectNodes("/SecDetails/Security");

foreach (XmlNode xn in nodelist)
{
here I should be able to repeat the node

for (int i=1; i<=10;i++)
{
I am struck here.
}

}

Look at the XmlNode class, in particular, the ParentNode property and the AppendChild and CloneNode methods.
You should have now all the element you need to perform your task.

Mouse and button position difference

23-Sep-09 6:34

Now I'm even more confused, I don't see a relation between what you have posted here, and the XML statements from your original post.

If you are saying that you don't know how to format a string in C# then I suggest you look at the documentation for the String class.

If you are unsure of the Xml data formats then look at the items referred to by Mirko1980.

If you are having trouble understanding the for or foreach statements then take a look at the C# documentation.

Hello,
I wanted to make a small game.. but I noted that the (X,Y) of the mouse and the button, if you are at the same pixel, are different. Look at the picture:

Here I'm pointing in the center of the button (where the red point is..) and the (X,Y) of both of them are different:
http://i34.tinypic.com/2ur9nx3.jpg[^]

Here I'm out of the button and its the same (X,Y) (red point..):
http://i37.tinypic.com/311tatz.jpg[^]

So why is this happening, and most importantly, how to fix this?

Thanks.

I don't understand the question..

Why would the position of the button change? Only the position of the mouse cursor would change when you move the mouse...

I mean that when I put the mouse over the button, they both should have the same (X,Y).. but thats not happening..

Why is that?

I'd have to see some code, as I'm not able to duplicate your error.

I did a simple program just to check what was the problem.
The program:

private void Form1_MouseMove(object sender, MouseEventArgs e)<br />
{<br />
    textBox1.Text=MousePosition.X.ToString();<br />
    textBox2.Text = MousePosition.Y.ToString();<br />
    textBox3.Text = button1.Location.X.ToString();<br />
    textBox4.Text = button1.Location.Y.ToString();<br />
}

which will show the (X,Y) of the button and the mouse..

and the problem is that even if u aim at the same pixel (the mouse and the button..), the (X,Y) are not the same..
