In a form, I add some menus whose short cut are Ctrl-C Ctrl-V and Del for copy/paste/delete action.But the shourt cut make the copy/paste/delete functions achieved by system and acused by keys press(Ctrl-C Ctrl-V and Del) can't do any more .As the functions of Ctrl-C Ctrl-V and Del have been achieved by system, I don't want to redo it and just only use the system achievement! How can I transfer the message to system and let it to process avoiding to process it by myself?

Hi everybody
I built a form to send/receive information between 2 IPs.
To do that I had to create another thread, but the problem is that when I'm closing the form the debug mode stay turned on in VS, and obviously it is because I created another thread, so the app is not REALLY closed (only the form).
I'm trying to kill the thread in the FormClosing event using thread.Abort() (I placed my new Thread as a private member called thread). most surly I'm missing something pretty basic, can anyone help me with this???
Thanks!

did you think of creating a "switch" variable?
you could add a private variable to your class called AbortThread (its boolean) and set it to false initially. When closing the form, you set it to true, then you do
while (mythread.ThreadState == ThreadState.Running)
{
Threading.Thread.Sleep(20);
}
In the Threadfunction you have to modify the loop condition (i assume you have one, otherwise the thread would not keep on running) and add a "&& !AbortThread" to it.
This way it will break the thread loop when closing the form.
If you can reduce the code to a minimum paste it here or put it somewhere online if you can't solve the problem with this hint.
good luck,
mik

Pretty hard to answer without knowing how you're building your setup.

Hello again, I really need your help in getting the code for the following ques.:
1. When a user selects multiple rows in the DataGrid, how can I get them programatically? In case of a single selection, i can use something like: datagrid.CurrentSelection.
2. What's the code used to prevent the user from getting the Task Manager window upon pressing Ctrl+Alt+Delete?
Thank you so much, ur help is much appreciated!

You don't.

1 - you can iterate over all the rows and find which ones are selected
2 - you may be able to do this with a keyboard hook, but why would you do such a user hostile thing ?

Hi,
My program writes this xml file:
<?xml version="1.0" encoding="utf-8"?>
<Root>
<CarInformation />
<DateOfBuilding>9/15/2006</DateOfBuilding>
<TimeOfBuilding>9:48:51 AM</TimeOfBuilding>
<CarInformation />
</Root>
The "CarInformation" node is the problem.
It starts and ends with '/>'.
This is how it should be:
<Root>
<CarInformation>
<DateOfBuilding>9/15/2006</DateOfBuilding>
<TimeOfBuilding>9:48:51 AM</TimeOfBuilding>
</CarInformation>
</Root>
This is my code:
class XMLWriter
{
XmlDocument xmlDocument = null;
string path = Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory);
XmlElement element = null;
XmlNode node = null;
XmlText text = null;
public XMLWriter()
{
this.xmlDocument = new XmlDocument();
this.xmlDocument.Load(path + "/file.xml");
}
public void WriteStartNodeAfterRoot(string startNode)
{
this.node = this.xmlDocument.CreateElement(startNode);
this.xmlDocument.DocumentElement.AppendChild(this.node);
this.xmlDocument.Save(path + "/file.xml");
}
public void WriteToXMLDoc(string elementString, string attribute)
{
this.element = this.xmlDocument.CreateElement(elementString);
this.text = this.xmlDocument.CreateTextNode(attribute);
this.xmlDocument.DocumentElement.AppendChild(this.element);
this.element.AppendChild(this.text);
this.xmlDocument.Save(path + "/file.xml");
}
public void WriteEndNodeBeforeRoot(string endNode)
{
this.node = this.xmlDocument.CreateElement(endNode);
this.xmlDocument.DocumentElement.AppendChild(this.node);
this.xmlDocument.Save(path + "/file.xml");
}
}
What am i doing wrong?
Thanks in advance!

You have to get away from the concepts you used when working with the XmlTextWriter. You're now working with the DOM and there is no thing such starting an element and then end it somewhat later.
You create an element, append it as child to some other element and if it should have some child nodes itself they have to be appended too. A good example is the WriteToXMLDoc method where you create an element, append it to the documents root element and afterwards append a text node to the element itself.
To get the wanted XML you have to append the elements created inside WriteToXMLDoc to the previously created carinformation element instead of the xmlDocument.DocumentElement. This will require some refactoring of your class but that shouldn't be too hard.

Hi Stefan,
I refactored my class. I removed the 2 methods wich i don't need according to you.
This is how it looks like now:
class XMLWriter
{
string path = Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory);
XmlDocument xmlDocument = null;
XmlElement element = null;
XmlText text = null;
public XMLWriter()
{
this.xmlDocument = new XmlDocument();
this.xmlDocument.AppendChild(this.xmlDocument.CreateXmlDeclaration("1.0", "UTF-8", null));
this.xmlDocument.Load(path + "/file.xml");
this.xmlDocument["Root"].AppendChild(this.xmlDocument.CreateElement("CarInformation"));
}
public void WriteToXMLDoc(string elementString, string value)
{
this.element = this.xmlDocument.CreateElement(elementString);
this.text = this.xmlDocument.CreateTextNode(value);
this.xmlDocument["Root"]["CarInformation"].AppendChild(this.element);
this.element.AppendChild(this.text);
this.xmlDocument.Save(path + "/file.xml");
}
}
This is how the output of the xml file looks like:
<?xml version="1.0" encoding="utf-8"?>
<Root>
<CarInformation>
<DateOfBuilding>9/15/2006</DateOfBuilding>
<TimeOfBuilding>1:01:13 PM</TimeOfBuilding>
<DateOfBuilding>9/15/2006</DateOfBuilding>
<TimeOfBuilding>1:02:06 PM</TimeOfBuilding>
</CarInformation>
<CarInformation />
</Root>
It adds everything within the first "<CarInformation>".
What am i doing wrong this time?
Thanks in advance!

this.xmlDocument["Root"]["CarInformation"].AppendChild(this.element); The above line always successes the first found CarInformation node. Replacing it with the following should resolve the problem
this.xmlDocument.DocumentElement.LastChild.AppendChild(this.element);
