I'm not sure I follow that, but do you want something like this?
string abc = string.Format (@"
<html>
<head>{0}</head>
<body>
{1}
{2}
</body>
</html>"
, dr [ "Layer" ]
, dr [ "Shape_Area" ]
, dr [ "Shape_Leng" ]
) ;
(Where dr may be a DataRow, or possibly a DataReader?)

i think not use Because fill Dynamic column .When fill 1 col, When fill many col.
client respond : "...[Name_col7]...[Name_col5]..."
app use this string to fill allow Name_col
respond to client new string.

The best way to do this, is to write a loop and use a stringbuilder. Assuming the strings between the values are consistently the same.

Hi,
I tried a VS Integration Package, which will add a toolbar to the visual studio 2005.
Now, It can work on the machine with SDK installed.
But, if the SDK is not installed, the Package will be seen and can't work.
Appreciate your suggestion.

What SDK ?

Visual Studio 2005 SDK 2007.2
Add a toolbar button to the VS2005 IDE.

Hi,
Are there any difference in performance between these codes:
<br />
MyClass _myClass = new MyClass();<br />
string _myString = "";<br />
_myString = _myClass.GetMyString();
and
<br />
MyClass _myClass = new MyClass();<br />
string _myString = _myClass.GetMyString();
In the first case, the string variable has been explicitly initialized.
While in the second case, it has been implicitly initialized.
Well, I understand that the difference in performance cannot be noticed.
But I'm just curious to learn about it.
Thank you very much.

If you replace "" with string.Empty, then I think performance will be equal.

So you mean in this scenario, the second case (implicitly initialization) yields better performance?

yes, because the first creates an empty string, which is then discarded. string.Empty maps to an empty string that already exists, so doesn't cost anything.

I want to multiply 2 XML nodes and want to append the result in another XML node in C#.What will be the code.If there is already exist one XML file there.I want to do the coding in a Class File.
|
|
|
|
|
Select the nodes, grab the values, multiply them and stuff the result in.
What specific part are you stuck on ?

This is the code:
This code is actually calculating one specific node with a user defined rate value.But this code I made for one sample windows application.
But now I need only one class file where no user defined rate is there.
rate is also available in the XML file.
And these code is for one specific node.I need to do the calculations for each and every nodes where Attribute is mention as coverage.
public void CalculateCommissionAmount(string policyXML, string rate)
{
XmlDocument xmldoc = new XmlDocument();
xmldoc.Load(policyXML);
XmlElement root = xmldoc.DocumentElement;
if (Convert.ToDouble(rate) < -5)
{
MessageBox.Show("Invalid Rate - Rate cannot be less than -5%.");
}
else if (Convert.ToDouble(rate) > 100)
{
MessageBox.Show("Invalid Rate - Rate cannot be more than 100%.");
}
else
{
try
{
XmlNodeList xmlnode = xmldoc.GetElementsByTagName("PersonalAutoVehicle");
for(int i=0; i

OK, so you need to use SelectNodes where the attribute exists. XPath allows you to do this.
Use SelectNodes, not GetElementsByTagName. XPath is a lot more flexibile than that.
use double.TryParse, not convert.ToDouble, that will tell you without throwing an exception if the conversion is not possible.

How to loop in every nodes of a XML file through C# codes
|
|
|
|
|
Assuming it's in an xml document, you can use the SelectNodes method to get through a list of nodes, then you'd need to recurse from there.
However, I believe that an XmlReader just steps through them, that may be better/easier.

Thanks,
But my scenario is:
There is a already existing Xml file.I have to take to nodes from there multiply it and result will come in the 3rd node that will be created dynamically.Coing in C#.
|
|
|
|
|
OK, so you don't want to iterate over every node, at all. You have specific paths you can pass into an XPath to get the values you want, you can use int.TryParse to get the numbers out, and then you need to add a node. XmlDocument is what you need. And probably a good read of the MSDN, it doesn't sound like you know much about using XML, yet.

Yes it's true,
After that I need loop also to itarate for each an every nodes.

|

OK, well, I answered that already.

how do you attach a serial command to a button in c#?
i have a lutron rs232 controller for my lights, and i want to know how you attach an on/off command to it.
this is what i have
private void button1_Click(object sender, EventArgs e)
{
SerialPort port = new SerialPort("COM1", 9600, Parity.None, 8, StopBits.One);
port.Open();
port.Write("SDL,1,0") //just an example, "Set Dimmer Level, zone 1, 0 for off"
port.Close();
}
now the (SDL,1,0) i've put a "/r/n" as well, but i get no response.

I wouldn't. I'd put all the serial communications in a class (or classes) of its own. I'd then call that class from the user interface.
