In most cases you don't whant to do:
public ArrayList Ingrediants
To initialize the object:
private ArrayList _Ingrediants = new ArrayList();
To expose contents of the list publicly use IEnumeration or IList or something rather than returning the reference to the list.

I would rather code like this:
public Gatorade()
{
_Ingrediants = new ArrayList(0);
}
public ArrayList Ingrediants
{
get
{
if (_Ingrediants.Count == 0)
{
this.IngrediantsList();
}
return _Ingrediants;
}
}
private void IngrediantsList()
{
this._Ingrediants.Add("Water");
this._Ingrediants.Add("Sucrose Syrup");
}
of course _Ingredients is a private variable. Do not expose method when it is not necessary. Follow good encapsulation.

i need to create a font property to a control that i have created ,
can someone help me ?

Hello,
I think you have to pick one of these possibilities.
public override Font Font
{
get
{
return base.Font;
}
set
{
base.Font = value;
}
}
private Font _font;
public new Font Font
{
get
{
return _font;
}
set
{
_font = value;
}
}
public new Font Font
{
get
{
return base.Font;
}
set
{
base.Font = value;
}
}
private Font _myfont;
public Font MyFont
{
get
{
return myfont;
}
set
{
myfont = value;
}
}
Hope you found youre solution!
All the best,
Martin

Hi!
I have a textfile which contains Name and Value (each name has a value). I want to display ONLY the names in a listbox. And it should be the names with the 10 highest scores. The highest score first...
I do know how to fill the listbox with all the names. But I cant get around to the other...any suggestions?

Show us how your txt is formatted
If it's something like "name=value" then you could do something like that
a) string[] lines = File.ReadAllLines("highscores.txt")
b) create a class:
struct Highscore
{
public string name;
public int score;
}
b)
List<Highscore> scores = new List<Highscore>();
foreach line in lines {
Highscore h = new Highscore();
h.name = line.Substring(0, line.IndexOf('='));
h.score = int.Parse(line.Substring(line.IndexOf('=')+1));
scores.Add(h);
}
c)
scores.Sort(... some IComparer to sort for score ...)
d)
for(int i=0; i<10; i++)
listbox.Add(scores[i].name);

I'd like to convert this to XML, I think it's best to do this programmatically. I'm considering using C# or Perl to do this, but I'm open to other ideas. I have the following questions:
- With Perl, setting up my regex will be elegant, but I don't know if Active Perl has any way of producing an XML file.
- With C#, it might be faster, but I don't know what class I would use to produce the XML and serialize it to disk.
All information and advice is welcome!
Thanks a lot,
Richard

Look in the System.Xml namespace. Also look for articles on CodeProject and msdn.microsoft.com that might be tutorial type articles.
YOu can use a DOM object System.Xml.XmlDocument or perhaps a XmlWriter would work better for your solution.

use regular expression object in C#
1. Use Regex
2. Do Grouping in Regex
3. Use MatchEvaluator if needed
4. Add the grouping result values to the dataset.
5. Save Datset to Xml.
You are done!

Hi All,
I Have created a windows service in C# and I want to run an exe which was created by me earlier from this service when the service starts.
I can see the exe running in the task manager but I am unable to see the UI of the exe
Please help me as this is urgent.
Thanks.

If you go into the services control panel and double click your service, you will see a tab in the ensuing dialog labelled "Log On". Click on that and then select the checkbox under the "Local System account" radio button marked "Allow service to interact with the desktop". I'm not sure if this will work for you, but give it a try.
The preferrable way to manage your own services is to create a service with no UI and then build a second Windows Forms application (possibly even one that runs in the tray) that can connect to the service and control it. You can also use remoting if you want to communicate with your service in some other way than just telling it to start, stop, and restart.
Hope that helps.

I am working on an application that has hundreds of try/catch blocks that output to Console.Writeline() on error. This is great for debug mode as it gets picked up in Visual Studio. I am curious where the output goes when I am in release mode. Is there an app that can pick this up? Are there serious performance implications for leaving them in for Release mode?
Thanks!
Hogan

If there is no Window open that catches stdout (like a Console or the VS output window), then imho it goes nowhere. Use Trace.WriteLine to print debug output.
You can capture it with DebugView in Debug and Release mode

Didn't work. Put my app in release mode. Launched it in Visual Studio .NET and stand alone and nothing got logged. Guess I'll have to do something else.
Thanks

Works fine for me, DebugView captures my Trace.WriteLine.
You might also try this:
DefaultTraceListener listener = new DefaultTraceListener();
listener.WriteLine("TEST");

Greeg,
Sorry about my quick response. I missed using the Trace part. I was just using my Console.Writeline... I think I am going to convert them all to using NLog in Release mode so I can turn them off if I don't need them. Thanks for your help!

Hi there.
Apologies in advance if i'm posting this question in the wrong section.
i'm wondering if it's possible to change the layout of the rdlc report at runtime (preferably without having to generate the .rdlc file from code). For instance, i want the user to be able to select which columns to display in a matrix. Based on those choices, the matrix must adjust to hide those non-selected columns.
Using the "expression to determine visiblity" feature hides the data, but there's a blank gap left in its place (makes the report look really... dodgy  ). I was thinking of putting in a function that said if the parameter passed through was false, set the matrix column width to 0 - except that it won't let me do that.
So, is there another way? Short of programmatically creating the report, or having awful-looking gaps.
Thanks

The way I have done things like this in the past is have a dynamic XML generator. The XML will be used as the Code behind the report.

I have a ListView and a custom IComparer for sorting. Which was working fine. I added a couple groups to the ListView, and now the sorting does nothing. The IComparer is processing each ListViewItem, the ListView just seems to ignore it.
Has anybody dealt with this? What am I missing?
