Lol. What is an "assgroup"? 
What is it that you have in the session variable? Is it something that can be interpreted as a color?
Have you examined the html code that is produced, so see what value you actually get?

Hello,
I have an app that I use to get poll for the hostnames on my local network.
I use this method to get the information.
System.Net.IPHostEntry hostEntry = System.Net.Dns.GetHostByAddress(address);
The problem is that when GetHostByAddress(...) fails because there is no machine at a given IP address, it throws an exception that takes a long time (a few seconds).
Is there a faster method to call?
Is there a method that does the same thing, but sets an error value instead of throws an exception when a bad thing occurs?
Is there some kind of timeout setting that I can set to like 20 milliseconds? (I can be assured of always being on a lan with a fast response)
I use a whole bunch of threads to speed up the application, which makes the wait more tolerable, but it still takes way too long for my taste.
Is there a better method to use in .Net 2.0
Thanks.

Use the asynchronous BeginGetHostEntry method, it will not block.
(You can also use BeginGetHostByName, but it's marked as obsolete in .NET 2.0)

ammoh - Microsoft is still actively improving the performance of the C# language and libraries. For information on using C# in scientific computing, check out this MSDN Magazine article[^]. The "Related Articles" section at the bottom of the page also provides some good advice on this topic. It's not too hard to relate these scientific computing concepts to gaming.
Good luck!

When Microsoft delved into writing LongHorn, the CLR team was given a directive by Bill. Make the CLR and C# run at C++-compiled speeds. This is probably a part of why it is slowly coming out. It is an undertaking, but the JIT now builds your IL AND optimizes the execution! I think you will find both languages coming out equal in speed.

hi
i have an app in which i can drop objects onto a form and move them, it consists of graphics (lines), i am using double buffering to avoid filckering in the parent control which is a panel,but when i add controls to this panel dyanamically, the double buffering effect is not there, i move all lines conneted to a control when the control is moved , at this time flickering occurs, please help.

Hi,
I wrote my user control to have my transparent image button using Windows forms.
For transparency, I need this:
protected override CreateParams CreateParams<br />
{<br />
get<br />
{<br />
CreateParams cp = base.CreateParams;<br />
cp.ExStyle |= 0x00000020;<br />
return cp;<br />
}<br />
}
and this:
protected override void OnInvalidated(InvalidateEventArgs e)<br />
{<br />
<br />
Transparenz zu erhalten<br />
this.SuspendLayout();<br />
this.Width--;<br />
this.Width++;<br />
this.ResumeLayout();<br />
<br />
base.OnInvalidated(e);<br />
}
and this:
protected override void OnPaintBackground(PaintEventArgs pevent)<br />
{<br />
}
It's working fine, but it flickers a bit. If there wouldn't be the overridden createParams, I could use double buffering. But, in this case transparency wouldn't work.
Do you know a way to have transparency and double buffering?
Regards,
Andreas

I have a listbox that a user populates. I want to only allow single spacing to be added to the listbox.

You can use a regular expression with the pattern " {2,}" to replace multiple spaces with a single space.

Thanks alot  That was a huge help. This is how I used it.
str1 = " spaces morespaces ";
str2= Regex.Replace(str1," {2,}", " ");
I noticed that it replaced every occurence of a mulitple space with a single space even at the beginning and the end. So I used:
str2 = Regex.Replace(str2,@"^\s*(.*?)\s*$", "$1");
to trim all of the leading and trailing spaces
Result:
"spaces morespaces"

You can just use str2 = str2.Trim() instead of writing your own regular expression.

I have a puzzle that would require some assistance by somebody who is knowledgeable about control arrays. If I had a control array of say 85 elements, and I would like to shuffle them so that they are randomized, is there an efficient approach that would work?
Initially, I would suppose that there would be a requirement to have two arrays, and that each element would be randomly "popped" off of the first array and placed (I forget the other term) onto the second array. Then, the first array would be re-dimensioned so that there would be one fewer elements. The procedure would continue until the first array contains zero elements.
Alternatively, as I recall there is some kind of Array.Randomize() routine. This would permit the randomization of one array without the need for a second array. Could one of you array gurus kindly provide some additional information and to fill in the blanks?
Say that I have an control array like so:
private Control[] controlName = new Control[85];

The following should do what you want.
Control[] controlName = new Control[85];
private void Shuffle()
{
ArrayList list = new ArrayList(this.controlName);
Random rand = new Random();
int j = 0;
for (int i = 0; i < this.controlName.Length; i++)
{
j = rand.Next(list.Count);
this.controlName[i] = (Control) list[j];
list.RemoveAt(j);
}
}

Thank you, Stefan. Here is a little twist. The elements of the control array are dynamically instantiated at run time. Is it possible to randomize elements from the control array?

I'm sorry, but I don't understand your question. Could you rephrase it and/or explain in greater detail what you want to do.

Hi,
I want to control the show/hide to another program. I use Process to start the program and make the initial window status Minimized. then I use Process to get the program main window handle and use windows API showwindow to hide the program i just started.
Everything looks fine but one thing. some of the control's visible property (or event, like viisble changed) in the started program are not correct. for example, the button is visible in the GUI, you can click and execute something, but you always get false when you check (get) the visible value . but I can use windows Api like iswindowvisible to get the right visible value.
I can use API to set/get the right value, but the related event fired are not correct!!
BTW, the program I started is created by C# (VS 2005).
Does anyone have some idea about this.
Thanks a lot in advance.

Hi folks
Is there any way of manipulating mp3 files such as:
1) extracting a part of a file (the actual data) and saving it somewhere
or
2) concatenating say two files to produce a third file and saving that file?
Kind regards
Ross

Well, if you aren't looking to do it in code - or want an easier way - check out Audacity - it is open source and does this - you just need the LAME MP3 encoder for it.
If you needed to do it in code and were not doing a commercial release, I think you could paste their code into your app to do this.
