You can also take a look at this article: http://www.codeproject.com/useritems/idisposable.asp[^]
Finalizers are expensive to use in that they are difficult to write properly and add an additional memory cost to your finalizable object. Any time a finalizable object is created it is placed in a special queue that must be checked each time the garbage collection cycle runs. This happens even if you never actually use the object.
The best approach is to implement the IDisposable interface and the Dispose pattern properly, and only implement a finalizer when absolutely necessary.

Hai Everybody,
I am having a tree view in that the nodes are in a hierarchical manner.
The nodes are checkable.
Now when some child nodes are not selected, then I have to make the parent node check box to have the check state "Indeterminate".
But there is no Check State property of the tree node.
Then i tried to convert it as a check box in code, but it is giving the error indicating that it is not possible.
Can any one give me the solution for this?
Best Regards,
M. J. Jaya Chitra

Try this: Turn the treeviews checkboxes property _false_ and instead create an ImageList and set the treeviews stateimagelist to the imagelist. You can then create three images in the image list (checked/unchecked/intermediate), and use the nodes stateimageindex (or stateimagekey) to set the state image.
Let me know if it works for you, I've never done this before

One hacky type way to stop / slow windows from shutting down, is to show a MessageBox. So, in your apps onClose event (ie. Windows is trying to close your app for shutdown) show a message box while you make your log, then close it.
My current favourite word is: Waffle
Cheese is still good though.

hi , Thanks in advance for everyone who reads that!
How can i set a thread so that when i start it the calling thread returns to what it did before and the new thread continues from that point , or any other solution with similar effect ?
for example:
<br />
<br />
public void Some_Event(Object sender , EventArge e)<br />
{<br />
Console.writeline("Im the Old Thread: {0}",Thread.CurrentThread.Name);<br />
<br />
Console.writeline("Im the new Thread: {0}",Thread.CurrentThread.Name);<br />
<br />
SomeForm sf = new SomeForm(((String)sender).username);<br />
<br />
}<br />
<br />

Google finds this.[^]
You might also want to look at the TreadPool class (Google it). It provides a bit less control over the treads, but in returns handles queuing requets, creating threads etc automatically.

if i wouldnt read that msdn or google i wouldnt ask here ,
in the msdn they only show examples of
Thred t = new thread(ThreadStart(target));
if you read my question i need something a bit different , dont know if its possible thats why im asking.

beleive me, a lot of people do NOT consult MSDN or Google before asking, you are the (positive) exception here.
But to answer your question - No, you do not need anything different.
Where you have written "//Some code i dont know how to implement" the code (pseudo code, I am not sure delegate names and signatures match - find them in MSDN) is as follows:
<br />
ThreadPool.QueueUserWorkItem(new WaitCallback(ThreadMethod));<br />
}
<br />
private void ThreadMethod()
{<br />
}<br />
Depoending on how much control you want with the thread, you can use one of the alternatives (create a Thread object etc) instead of the ThreadPool.
If you REALLY want it in the same method you can replace the "new WaitCallback(ThreadMethod)" part with an anonymous delegate. But I really recommend you try to think of starting threads as follows:
1) The creating thread continues execution in the current method
2) The new thread starts running in a new method/scope.
it will help you later on as this is how the thread methods are designed - and how they are used by most developers.

The anonymous delegate did the trick ,
Thanks
i did something like that if that's what you mean:
<br />
public void my_multi_threaded_method()<br />
{<br />
Console.WriteLine("calling thread");<br />
<br />
Thread t = new Thread(ThreadStart(delegate() <br />
{<br />
Console.WriteLine("child thread");<br />
});<br />
t.start<br />
}<br />

plz any ine help me
i need a code for finding whether a file is exisisting in the folder if exist display the file woth some text or not create the file with some text and displaying message that file is created successfully using c#
|
|
|
|
|
you can use System.IO.File.Exists(string path) method to check whether the file exists or not.
good luck
|
|
|
|
|
using System;
using System.IO;
using System.Collections;
public class FileHandling
{
public static void Main(string[] args)
{
foreach(string path in args)
{
if(File.Exists(path))
{
// Your code should run here
}
else if(Directory.Exists(path))
{
//Your code should run here
}
else
{
Console.WriteLine("{0} is not a valid file or directory");
}
}
}
Happy Programming

you must first set the WorkerSupportsCancellation Property of BackgroungWorker instance to true.
then you can cancel it
good luck

You can't just cast your string however to whatever type you want it to be.
I haven't used the function myself, by but reading the documentation it should work like that:
StringCollection coll = new StringCollection();<br />
coll.Add("C:\\Test");
Clipboard.SetFileDropList(coll);
