Hi!
I am working on a Storage Area Network (SAN) performance mesuarement system by simulating Microsoft Word usage.
I've used Filemon to get the fileoperations MS Word are using during open/write/save/close on a document stored on another computer. I'm gonna use this information to create a program that simulates many MS Word users at the same time, accessing a file on the Storage Area Network. What is the best way to do this? Should I create a file filter for these operations?
Thanks for any help.

No, if you just want the window to move a bit, DirectX is certainly not required. In fact, I'm not sure how it could help.
All you need to do is create a loop and set the window position within it to differing values, and possible call Application.DoEvents() to make sure the app responds to the events for you.

 Hi Good to See you.
For shaking two windows form in same machine or remote machine you can use Remoting Concept of .NET.In Three steps you can achieve this.
1. Create Server:That handle your request
2. A client: request Sender
3. your From.
For details mail me.

Please always search on your own before posting.
If you would just have searched for 'shake form' with this little field right beneath the CodeProject logo you would have easily found this.

Hey!
I am using System.IO.serialport(Framework 2.0 beta 1) to communicate throw the serial port(com/USB).
I have connected a function to the event DataRecived, and there is a steady incoming dataflow on this serial port. To be able to read the data I had to set DTEnabled = true.
Problem: Now I need to send some data back out on the serial port, but as long as I have a steady dataflow in to my program (that im reading) I cant send?
The data is not received on the other end.

I need to make some calculations from milimetres to pixels in my programme (for drawing) and I need a Dots-per-inch current value for this. Where can I get it? Supposedly in the WMI but isn't there a class which handles this in standard libraries by any chance? (It would even better if DirectDraw objects could perform drawing operations using milimetres coordinates, but I highly doubt it can be made

I thought GDI+ allowed you to set drawing units as inches ?

You can indeed set drawing units as inches (System.Drawing.GraphicsUnit.Point is 1/72 inch). Plus, you can get the DPI values from the System.Drawing.Graphics.DpiX and DpiY properties.
|
|
|
|
|
you can use the folowing function to make calculations and transformations betwin different coordonating spaces
Graphics.TransformPoints

I have a web service that has to log a few bits of information when a method is called. One bit of information i need is the external IP of the client...
Context.Request.UserHostAddress.ToString()
and
Context.Request.ServerVariables["REMOTE_ADDR"]
both will return 192.x.x.x addresses for users who have a local address (almost everyone).
there has to be a way to see the actual remote ip that is calling the request, right?

Hi. I'm adding a bunch of XmlNodes into a ListBox control. Now, when I look at the list box, I see a bunch of System.Xml.XmlElements (which is expected).
I would like to be able to display in the ListBox some specified text, but the problem is, the text is not just a public property in the XmlNode class, so I can't use DisplayMember. In order to get the text, I need to run a XmlNode.SelectSingleNode().InnerText. So far, I haven't had any luck putting anything like that into DisplayMember.
Is it possible to get the inner text of a single node from an object in my ListBox and have it displayed instead of System.Xml.XmlElement? Or am I going to have to wrap it in a class or something?

For any item added to a ListBox, the text returned by .ToString() is displayed.
The simplest solution is to create a wrapper class that overrides ToString()
public class NodeItem
{
private XmlNode m_node;
public XmlNode Node {...}
public NodeItem(XmlNode node)
{
m_node = node;
}
public override string ToString()
{
return m_node.InnerText;
}
}
myListBox.Items.Add( new NodeItem(myNode) );

Is that text acessible via property? If no, you MUST wrapp it. ( and/or override ToString() ).
Docs say it pretty clearly.
"A String specifying the name of a property of the object specified by the DataSource property. The default is an empty string ("")."

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.

that went way over my head. thanks for your time.

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!
C.N.
