Yeah, but the code was so clean looking...

This is not a simple solution like the above, but it is easy to do in Visual Studio: get the schema for your documents, create a typed DataSet from the schema, use a dataset instance in your form, and set the appropriate table/column for the ListBox.DataSource and ListBox.DataMember properties.
Just a thought.

There is 2 ways to achive this... one is to write a wrapper around an XmlNode, the other (and slightly preferable IMHO) is to write a little ListItem class.
<br />
class XmlNodeInnerTextListItem<br />
{<br />
private string data;<br />
<br />
public XmlNodeInnerTextListItem(string xpath, XmlNode node)<br />
{<br />
this.data = node.SelectSingleNode(xpath).InnerText;<br />
}<br />
<br />
public override string ToString()<br />
{<br />
return this.data;<br />
}<br />
<br />
}<br />
I tested with this code and it worked fine:
<br />
XmlDocument xmldoc = new XmlDocument();<br />
xmldoc.LoadXml("<root><node><data>foo</data></node><node><data>bar</data></node></root>");<br />
<br />
XmlNode node = xmldoc.DocumentElement.FirstChild;<br />
this.listBox1.Items.Add(new XmlNodeInnerTextListItem("data",node));<br />
this.listBox1.Items.Add(new XmlNodeInnerTextListItem("data",node.NextSibling));<br />
Listbox had "foo" and "bar" in the list!

Sorry, Xml went wrong. The xml i used in that <code>LoadXml</code> call was
<root><node><data>foo</data></node><node><data>bar</data></node></root>

Hi,
I'm quite new to C# especially when using GDI+. I saw the solution for zooming an image, but I didn't manage to zoom.
I couldn't quite understand what the parameters in "new Matrix(scale,0,0,scale, xoffest, yoffset);" mean I think
In order to zoom my image by 25% I implemented your code in the following way:
float scale = 25f/100f;
pictureBox.Image.Save("OriginalImage.png",ImageFormat.Png);
Graphics g = Graphics.FromImage(pictureBox.Image);
g.Transform = new Matrix(scale,0,0,scale, 0, 0);
pictureBox.Image.Save("ResizedImage.png", ImageFormat.Png);
pictureBox.Image = Image.FromFile("ResizedImage.png"); //to load the new image
What am I doing wrong please?
Thanks A Lot!

Hi,
can you kindly give me an example of how can I zoom an image in a PictureBox using the Matrix method (as I had shown in the code-snippet) or any other method please?
Thanks
C.N.

You are not zooming the image itself. Instead, you are telling the view (Graphics) how to render the image.
This is the advantage of using Transforms... drawing code does not change. Just the parameters of the rendering. Derive a class from PictureBox (or control type of choice...) and modify the OnPaint routine appropriately.
public class ZoomPictureBox : PictureBox
{
private float m_zoom = 1.0F;
public float Zoom
{
get{ return m_zoom; }
set{ m_zoom = value;
if( this.Image != null ) Invalidate();
}
protected override void OnPaint(PaintEventArgs e)
{
Matrix matrix = new Matrix();
matrix.Scale( m_zoom, m_zoom );
e.Graphics.Transform = matrix;
e.Graphics.DrawImageUnscaled( this.Image, 0, 0 );
// base.OnPaint (e);
}
}

Hi all,
I am developing a c# application and there are two version of .net Framework installed in my computer. They are <1.0> and <1.1> I want to know exactlly which .net framework I am using and how to choose a framework to run.
I can run my application successfully with the enviroment that <1.0> and <1.1> frame are installed together.But when I install my application onto anther computer which only <1.1> framework is installed.The applicaiton can not run as same as the previous one.I am wondering?
Any suggestions.Thanks in advance

1.1 should be able to run 1.0 apps fine, minus a few minutia quirks, mostly involving remoting.
To see which version you've got running, go into %windir%\Microsoft.net Framework\ and you see the versions installed. Visual Studio 2003 uses .NET 1.1, Visual Studio 2002 uses .NET 1.0.

Hi,
Does anyone know of a .NET library for reading and writing PalmOS database files (pdb/prc) on the desktop?
Cheers!
|
|
|
|

Palm database records are pretty basic things, they are basically a header, and then raw data in the format specified by the app. I reckon you'd do as well to read the docs for the app that's writing the file, then reading it yourself.
Can you write some Palm stuff ? I'd start by creating some small databases that contain a small number of known values.
I don't know of any library.

I'we allready written a DB reader/writer in MFC/C++ for a previous project and I think I now have figured out how to best invoke it through C#, allthough it would have been nice with a finnished .NET library for this.
(I'm writing the Palm app that reads the data and the desktop app that generates the data, so the raw data format is not a problem.)
Thank's anyway.

hi, how i can make a trial version of the windows project that i do using c# language,.... help me plz
Thanks alot

You can make it by taking the date within the first runtime to the application and store it in the config file in the same directory,and then after finishing your period jst disable the application.
|
|
|
|
|
But, what if the user re-installs the application again after the trial period expires? Will it not reinstall the config file with a fresh trial period?
Secondly, can't the user directly edit the date in the cofig file? Even if you encrypt it, the encryption key will have to be strored somewhere in the config file or the program itself, so that the user can still decrypt the date and edit it, may be after some efforts.
So, will this solution work?

|
|
|
|
That depends on your thoughts, you can create a registry entry to act like a flag to you ,or you can try anything else.
