That's what you use! You just move the file to the same directory the file is in, but just supply the new filename.

Dim fi As New FileInfo("C:\dir\dir\test.txt")
fi.MoveTo("C:\dir\dir\newText.txt")

... is one way to do it.

use the code list:

p1.X = 10;
p1.Y = 15;
p2.X = 68;
p2.Y = 100;
path.AddLine(p1, p2);
g = this.panel1.CreateGraphics();
g.DrawPath(Pens.Black, path);

Then，I draw a line on the graphic.In the event of Mouse_Move,I catch any point and want to know whether the point in the path of the line.
So I use the funcation of GraphicsPath.IsVisible(),but whenever the funcation always return false.
Can you help me? Thanks!

Extracting attribute information from an XML file

I'm learning C#, and hit this wall while trying to extract attrib info from an XML file. The method I'm using is

void Button4Click(object sender, System.EventArgs e)
{
    string fileName = "..\\..\\books.xml";
    XmlTextReader tr = new XmlTextReader(fileName);
    listBox1.Items.Clear();
    int countAttribute = 0;
    while(tr.Read())
    {
        if(tr.NodeType == XmlNodeType.Attribute)
        {
            countAttribute++;
            string displayString = tr.Name;
            displayString += tr.Value;
            listBox1.Items.Add(displayString);
        }
    }
    tr.Close();
    MessageBox.Show("Encountered " + countAttribute + " attribute(s)");
}

The XML file indeed contains attribs, and here's a part of it:

<book genre="humor" publicationdate="1897" ISBN="0-863411-58-1">
	<title>Three men in a boat</title>
	<author>
		<first-name>Jerome</first-name>
		<last-name>Jerome</last-name>
	</author>
	<price>4.99</price>
</book>

However, the list is not getting populated and the message box tells me it encountered no attributes at all. Am I doing something wrong? Can somebody please tell me how to get the attribute names and values?

Thanks in advance! Smile | :)

Cheers,
Vikram.

Hi Vikram,

You can try this :

	string fileName = "..\\..\\books.xml";<br />
	XmlDocument xmlDocument = new XmlDocument();<br />
<br />
	xmlDocument.Load(fileName);<br />
<br />
	foreach (XmlNode xmlNode in xmlDocument.SelectNodes("//@*")) // XPath query <br />
	{<br />
		// Add your code here<br />
	}<br />

Hope that helps,
Bruno

Hi, Bruno! Thanks for the reply. It works like a charm and I'm able to extract the info I need. Smile | :)

Is there some way to do it using XmlTextReader, since I might want to do something else with the other elements? Smile | :)

Cheers,
Vikram.

Hi again,

You can eventually pass an XmlReader to xmlDocument.Load method instead of a filename !

Code to flip a window

I'm looking for a code to flip a window, like in the Tiger - Apple OS.
I though of the following algorithm but I can get it implemented right:

1. Capture the window who is about to be flipped.
2. Hide it and display the image.
This is the part which I don't know how to implement:
3. Start changing the image size so it looks like its being flipped.
4. Display a new window which is the "back side" of the original
window.

If anyone thinks that there is a better algorithm, or how to implement
the algorithm suggested, please...

As others have stated before: It is not possible.

Besides the whole approach of trying to use text files to store information you want not to be visible seems to be rather braindead. Dead | X|

The whole point of plain text files _is_ that the contents are readable with an arbitrary text editor.
If you want information to be unreadable for your users then use binary files!

Stor it in a seperate stream. It will only work with NTFS though. If the file is copied to a non-NTFS file systems the extra streams are lost. The data will also be lost if the file is copied using a "homemade" copy function reading the binary stream and writing it to the new file. And no, I can't remember how to open a separate stream, I just know it can be done.

hi there,

u can download a webpage from a site by using HttpWebrequest/HttpwebResponse (these are supported in .net, sorry I do not remember exactly the class name)

after downloading the content of a web page, just simply do parsing from the content to find out all hyperlinks in the page

Hope that helps

Access the web page through code and get it as web response. Use REGEX to extract all the available hrefs.

DataGridBoolColumn - event

JuergenLissmann18-Sep-05 18:54

18-Sep-05 18:54

In the Style definitions for a DataGrid I defined a DataGridBoolColumn to show Boxes for
the true/false-values in the DataView of the Grid.
To set/toggle Buttons I have to check out, if the Box in a [Row,Column] is set to Enable or Disable by the click-event / space-key (if cell selected).
I have included an eventhandler (DataChanged) for the DataTable which is bound to the Grid.
But only if the SelectedCell is changed, the event for DataChanged will be fired. So, how can I receive an event for the changed Value in the Box if the user do not change the Cell (only 1 Click in the Box to mark it) and won't leave the DataGrid (events validating/valdated therefore will not be fired) ?
Any Idea ?
- If Data is changed, you can see the shown pencil at the row-marker-column. May I fetch this event inside the Grid in any way? May this be a workaround?
