i'm creating a program that use a custom scrollbar made using 2 normal buttons with my own drawing.
The top button move a panel over the bottom move the panel down.
This panel show objects height the same 100 pixel all objects.
What is the better way to create a scrollbar like this?
If these items are many as 100 or 1000 it is absourd to create all them if i see just 20-25 at time, so what is the better way to scroll them without load the at the same time?
My software is like Outlook where all the item are the name - email - attach field, i can receive 2000 or more email, does outlook load all them in the same time showing just 30-40 in the visible area?
I hope to have me explained.

Outlook will look into it's database, get back the records being shown, and display them. It may cache a few either side to help the display when scrolling.

Use a WebRequest.

Try this
WebRequest req = HttpWebRequest.Create("http://www.codeproject.come");
String source = req.GetResponse().GetResponseStream().ReadToEnd();

double a b c;
...........
output.Writeline(""+a+"\t"+b+"\t"+c+"\t");
The problem is that output file, sometime a b c will have different precision
for example a=2.33 b=3.45 c=3.53330000001
I want a b c to have same precision (c=3.53)
how can i do it?

Specify the format you want when you convert the values to strings, for an example: a.ToString("N2").
Now you are implicitly converting the values to strings. Unfortunately the values will be boxed first, which is not very good for performance. Always convert the values before the string concatenation.

I am quite desperate with this, hopefully someone might help here:
So I have created my own add-in for visual studio. Now I want to catch the event of "line change". That is when the user no longer edits some line and moves to another.
In the "OnConnection" method of the addin, I add this line:
applicationObject.Events.get_TextEditorEvents(null).LineChanged+=new _dispTextEditorEvents_LineChangedEventHandler(Connect_LineChanged);
and in the handler I open a messagebox.
The problem is, that the add-in works perfectly, untill... I open a new XML file!!
then it stops working in any of the documents...
Am I doing something wrong?

The last time I was looking for a job I discovered that this was a euphamism for "we're going to give you lots of work in areas your not qualified for and give you no training and we want everything done by next Tuesday even although we realise that it is a 3 month project"
The jobs that are genuinely exiting don't need people to state they are exiting because it is obvious from the description. Jobs that are challenging are ones that allow the individual to grow as a person, and again that is obvious from the description.
However, since your description is "exciting and challenging" there isn't much to work with and I suspect that, quite probably, they'll turn out to be dull and tiresome.
So, prove me wrong - tell us what the job really is!

I'm a C# developer, with a C++ background. I'm a C++ MVP, as it happens. I love to work on projects that are 'exciting and challenging', so perhaps if you'd like to tell us what it is, you'll get resumes from people who are more in your app domain. Of course, advertising through a question board leaves me worried about your budget, but I always ask for 50% up front, as would anyone worth hiring, IMO. It's a simple concept of shared risk.

If the project is exiting, why are you hiring?

No offense, but:
Exiting as in "interesting", NOT as in "exit".
Cheers,

I know. I deliberately ignored the spelling error (should be "exciting").

Hi, I have made a small program that opens a data file in XML format, then searches through it for certain information, the problem I have is that if the first line of the XML text looks like;
<data xsi:schemaLocation="http://www.website.com" version="0.3" xml:lang="en">
it doesnt work, but if I change it so the first line is simply;
<data>
It does work.
The problem is that the data comes in the first way, which doesnt work for me, can anyone explain why it might be that this happens? I assume it is a simple, seeing as how I can fix it by simply removing a small amount of text.
(p.s. I am fairly new to XML so forgive me if this is really dumb!)
thanks in advance!

Standard question #1:
What do you mean by "not working"?

Ok good point!, this is an example;
private void button4_Click(object sender, EventArgs e)
{
StreamReader sr = new StreamReader(@"data.xml");
XmlTextReader xr = new XmlTextReader(sr);
XmlDocument docData = new XmlDocument();
docData.Load(xr);
XmlNodeList wikinodes = wiki.SelectNodes("data/page");
lblNodes.Text = dataNodes.Count.ToString();
}
When it works, lblNodes will show there are 1699 nodes, when it doesnt work it just says there are 0 nodes.
The XML file looks roughly like this;
<data xsi:schemaLocation="http://www.website.com" version="0.3" xml:lang="en">
<page>informationhere</page>
<page>informationhere</page>
<page>informationhere</page>
</data>
but will only work if I change it to look like this;
<data>
<page>informationhere</page>
<page>informationhere</page>
<page>informationhere</page>
</data>
I hope that is enough info, Thank you!

Try with the "/data/page" xpath instead.
Otherwise, it might be the schema that removed the nodes. Does the schema that the data references to exist?
Check the contents of the InnerXml property once the document is loaded, to see if the page nodes gets loaded at all.
