Read articles on this site. Look for articles that get higher ratings and have a read through the code. BTW - the code that you quoted as being written by a professional developer isn't very good. This should have been done in a much more robust fashion, e.g.
public enum SpecialFolderType
{
Desktop,
Personal
}Then further on...
private Dictionary<SpecialFolderType, string> _folders = new Dictionary<SpecialFolderType, string>();
...
_folders.Add(SpecialFolderType.Desktop, Environment.SpecialFolder.Personal); .. and so on.
Then you would retrieve it with
public string Desktop { return _folders[SpecialFolderType.Desktop].Value; }Obviously there are more things that could be done to beef this up even further, such as checking values and so on, but you get the idea.

Mr.Pete After I saw your code , I believe that you are right .
His code is not very good , but he is better than me , and you are better than two of us ....
thank you ...

Code Complete is a very good book for general style issues.
<blockquote class="FQ"><div class="FQA">Stark DaFixzer wrote:</div>lbl1.Text = Environment.GetFolderPath(Evironment.SpecialFolder.Personal);
lbl2.Text = Environment.GetFolderPath(Evironment.SpecialFolder.Desktop);</blockquote>
All that sucks about this is the variable names.
Stark DaFixzer wrote: public class SpecialFolder
{
private static string [] SpecialFolders = null;
static SpecialFolder()
{
SpecialFolders[0] = Environment.GetFolderPath( Environment.SpecialFolder.Personal);
SpecialFolders[1] = Environment.GetFolderPath( Environment.SpecialFolder.Desktop);
This is a waste of time in my book. All it does is rewrap something that is already exposed by the framework, and it obsfucates it. Unless there's ever a chance you want to change where SpecialFolder.Desktop points, it's just a waste of time to do this.

thank you Mr.Christian Graus
I will download this book ,
by the way ( may be the Specialfolders Class waste of time ) but the good practice would help you in the future to solve the big prb's

Yes, centralizing things so you can change them app wide in one place is a good practice. Good practices adhered to blindly become bad practices.

1. Datagridview has got a property called DefaultCellStyle which is used to control how cells are rendered in that row.
2. Use MultiSelect property of Datagridview class. You can find selected rows by using SelectedRows property. Intuitive, isn't it?

Create a notify icon for your app, then look at the NotifyIcon.BalloonTip method.

The error should be fine to ignore, I get those all the time.

I'm new to the thread concept so I apologize for what could be a simple question.
I have a process where I am creating a variable number of graphics objects (balls), each running in their own thread (not a ThreadPool).
As each object moves and bounces around the screen, I would like to check if the existing ball intersects any of the other balls. If they do, I need to remove the colliding balls, I assume using Abort.
I have been trying to see if I can loop through the currently active threads and compare using Rectangle.Intersects but I have not seen any references on a thread collection.
Any ideas or suggestions would be appreciated.

You can maintain a static list of ball objects that is available to all threads and use it to compare for intersection.
I am curious as to how many processors you have? Usually for such a scenario all of the thread logic would be handled via one thread and the drawing in another. That is really the simplest scenario.
To really split it up you need to seen each thread a region of control (not a ball) and have the thread check regions of control for intersections and then pass control to another entity to check for intersections when balls hit boundaries on regions of control.
Best bet, just use one thread for balls and one for UI. Also, use a rectangle for collision testing first to significantly increase performance.

Using threads this way is a bit odd. Typically you would use one thread and then tick the entire simulation. You will get *strange things* happening if you are ticking different parts at different rates, and having balls interact with parts of a ball thats halfway thru its collision detection code. Expect to use a lot of locking to get things right.
If you are doing this as an exercise in threads - then look at keeping a dictionary of Ball to Thread around.
If you just want some bouncing balls then immediately throw this threading away and do it in a single thread that loops through all the balls.

Thanks for the responses.
It was an academic exercise but I think it was a fairly poor practical example of using threads.

I want get all the occurences for one string (e.g. keyword) in an ASP or html file. But I want to ignore some special html/asp tag that includes the searched string (in my case it is "keyword").
for example:
1) this is a test keyword string. (I want this)
2) <a href='#'>the is second keyword</a> (I don't want this)
2) <%
'this is keyword in asp code
%>
(I don't want this)
I know regular express may solve this problem. But I don't know how??
Can somebody give me an example regular exression for this??
Thanks a lot!
