Thank you. After reading that it kind of reminds me of how I used buffers in C.

John Skeet has written about this[^]
This is an excellent introduction to this topic. I once scored brownie points in a Job Interview for referring to this stuff when asked why I didn't use StringBuilder in a simple one-time concatenation during a programming test. The interviewer didn't beleive me at first, but a quick test showed similar results to the article.

Hi,
I have defined a custom action for a library to ask for the approver's Name, Title and email-id for a document. This data entered should be taken programmatically to create a digital signature and add this signature inside the document.After this the document should be disabled from editing once signed(just like inserting a signature for a word document, but should be done programmatically). Can somebody post full working code for a sharepoint Visual studio 2010 project for this?
I have googled for the code but none are aiming at my request.
Much Thanks,
Nisha

Hi All
I am trying to find a way to optimise the below code for my web service
In my webservice i recieve 10 different XML files, each xml file is always the same format, at the moment i have 10 different methods to handle each one, the below code is an example of one of the methods.
The only difference between the methods are the local variables and the node attributes.
Instead of having 10 methods almost identical i would like to have just one.
Can anyone advise on the best way to achieve this ?
thanks
public void NavigateXmlSessionData(XPathNavigator xPathNav)
{
xPathNav.MoveToRoot();
xPathNav.MoveToFirstChild();
xPathNav.MoveToFirstChild();
string description, personId;
description = "";
personId = "";
do
{
if (xPathNav.MoveToFirstChild())
{
while (xPathNav.MoveToNext())
{
switch (xPathNav.Name)
{
#region NodeAttributes
case "Description":
{
StringBuilder strBuild = new StringBuilder(xPathNav.Value, 200);
description = strBuild.Replace('\'', ' ').ToString();
break;
}
case "PersonId":
{
StringBuilder strBuild = new StringBuilder(xPathNav.Value, 200);
personId = strBuild.Replace('\'', ' ').ToString();
break;
}
#endregion
}
}
xPathNav.MoveToParent();
}
ProcessRecord();
description = "";
personId = "";
} while (xPathNav.MoveToNext());
}

Not an answer to your question but if you want to optimize reading XML, use the XMLReader class. It streams the data so you don't have to wait for the whole file to be read and you don't have to wait for indexing to be completed.
Having 1 method instead of 10 isn't going to offer much in the way of optimization but it will make the code more maintainable. Just isolate the minor differences and pass them as arguments or enumerated values.

What problem do you have? That's the important part that's missing from your question.

32 or 64 bit?
Why is common sense not common?
Never argue with an idiot. They will drag you down to their level where they are an expert.

It's either not installed, or you're mixing environments. Read here[^].

i making a exam suite project what may coding behind login mail,password,for new user labels and what may be coding behind ok,cancel and sign up button

Some c# to make it work I guess?

I made a button that if clicked, it would get the element ID of an HTML button which is "ContinueButton" and then it would invoke a click on it. Just as coded below. So basically, it will click this HTML button and it would eventually lead to the next HTML page.
private void button11_Click(object sender, EventArgs e)
{
webBrowser1.Document.GetElementById("ContinueButton").InvokeMember("Click");
Now, after the next HTML page has loaded, it contains a web form. This web form has an element ID by "secretnumber."
I made a code below and it should fill this web form.
webBrowser1.Document.GetElementById("secretnumber").SetAttribute("value", "320");
}
However, the program stopped and it didn't fill the web form ("secretnumber"). Please help me.
I added this code too but it didn't seem to work.
while (webBrowser1.ReadyState != WebBrowserReadyState.Complete)
{
Application.DoEvents();
}

This is what I tried below, but it does not work
private void button11_Click(object sender, EventArgs e)
{
webBrowser1.Document.GetElementById("ContinueButton").InvokeMember("Click");
while (webBrowser1.ReadyState != WebBrowserReadyState.Complete)
{
Application.DoEvents();
}
webBrowser1.Document.GetElementById("secretnumber").SetAttribute("value", "320");
{
If button11 is clicked, it will automatically click an HTML Button with the element ID of "ContinueButton." Because "ContinueButton" is clicked, it would lead to the next html page. And in this next html page contains a web form with element ID of "secretnumber." I want that web form to be auto filled with "320" but it didn't fill it.
How can I make it wait for the next page to load and then automatically fill the web form with "320"?
