A Dictionary might be the way to go, but you will have to be very careful what you use for the key. If you use trackName it will complicate retrieving the display order. Even if you use displayIndex, implementing the move up/down functionality could get complicated.
Without thinking about it for a while, I don't have a better suggestion, but I'm sure that somebody will.

If by user defined, you just mean the user can reorder them manually, then just a dictionary works fine to create mappings of Tracks to Layers. I thought that the order of keys remains the order in which they were added, also, although I am not sure that the collection supports remove at index and add at index, I would have to hope that it did.

You can use queries with orderby clause - then you can have your displayOrder as a part of your Track schema and make sequence ordering by this parameter while maintaining Dictionary capability.

Just want to say thanks for the advise so far. You've given me some more things to think about and try. I'm going to spend today tinkering again and might post some code later for further advise.

Ok guys,
Looks like I've gone a thoroughly confused myself here. Perhaps one of you kind folks can chime in and set me straight.
Here are my requirements:
1. Collection of layers called layerCollection
2. Each Layer must have a Name property that is unique to the collection it resides in.
3. You can access each Layer in the collection by Name or Index[]
foundLayer = layerCollection.getLayer("Background"); <-- returns Layer with layerName = "Border"
foundLayer = layerCollection.getLayer("Border");
foundLayer = layerCollection [0];
foundLayer = layerCollection [1];
etc...
Help 
Once I figure this part out I'm sure sorting the layerCollection to reorder them will be a simple task.
Thanks again for your help and patience!

Impossible. It has nothing to do with .NET, it has to do with how your PC processes sound. That's precisely what DirectX is for.

my code is as follow. I need to fig out a way to handle if results dosnt find any thing sshow yes something was found or no users had been found at this time. Iv tried to fig this out but im unable to do so. Thank you for your time.
DateTime dt = DateTime.Today;
DateTime less5dt = dt.AddDays(-5);
This.cmb1.Items.Clear();
PrincipalSearchResult<UserPrincipal> results =
UserPrincipal.FindByLockoutTime(
adPrincipalContext,
dt,
MatchType.GreaterThanOrEquals);
foreach (Principal result in results)
{
cmb1.Items.Add(result.name);
}

You don't even have an if statement, so what's the problem with it?
What in this code is a "user"?
Is every result in results a user?

The users that are locked out in Active directory then it populates them in a cmb1
just want a statement to allow me to show a message to the user yes something was found or now nothing was found. and im unable to fig that out.

Hi,
bool someUsersWereFound = results.Count!=0;

first off THANK YOU !
sorry for the noobieness how would I incorporate this into my code?

Hi,
MessageBox.Show(results.Count.ToString()+" user(s) found");
PS: I strongly suggest you buy and read a tutorial book on C#. It will teach you the essentials in a structured way.

so the bool statment you showed me before i need to place that inside the foreach i understand the messagebox part just not the part on how to get the program to realise nothing is found then display the message nothing found. Iv tried and watched it when i debug the program but i cant fig it out.
Thanks again.

Hi
Is there a smart way todeserialize an object to form. Instead of typing textbox1.text = object.property..., after the object has been deserialized.
My form has a bunch of controls, and I was just looking for a different way of doing this. I am just looking for ideas I guess?

Personally, I prefer writing the code to set the values of form elements. Often the pursuit of automagic code features will cause you more pain than it is worth. However, you could use reflection if you really wanted to in a poor man's data binding fashion or implement the data binding interfaces to make your object a valid data source. Or make an object data source for which to bind your object.

You could try looking at the documentation for ApplicationSettings this gives some examples of doing this sort of thing.

Hi Everyone
please look at following two line this is not working when i execute my prject
int div = Convert.ToInt32(textBox1.Text.Trim());
ptr[0] = ptr[1] = ptr[2] = (byte)((ptr[0] + ptr[1] + ptr[2]) / div);
but if i remove the first line and enter an integer value in place of div variable it works such as following line.
ptr[0] = ptr[1] = ptr[2] = (byte)((ptr[0] + ptr[1] + ptr[2]) / 3);
Following is the full listing may it help you to figurout the problem
a method that convert a bitmap from colored to grayscale
//////////////////////////////////////////////////////////////////////////
public Bitmap GrayScale(Bitmap bmpimg)
{
BitmapData bmpData = bmpimg.LockBits(new Rectangle(0, 0, bmpimg.Width, bmpimg.Height), ImageLockMode.ReadWrite, PixelFormat.Format24bppRgb);
int remain = bmpData.Stride - bmpData.Width * 3;
unsafe
{
byte* ptr = (byte*)bmpData.Scan0;
for (int i = 0; i < bmpData.Height; i++)
{
for (int j = 0; j < bmpData.Width; j++)
{
int div = Convert.ToInt32(textBox1.Text.Trim());
ptr[0] = ptr[1] = ptr[2] = (byte)((ptr[0] + ptr[1] + ptr[2]) / div);
ptr += 3;
}
ptr += remain;
}
}
bmpimg.UnlockBits(bmpData);
return bmpimg;
}

why is int div = Convert.ToInt32(textBox1.Text.Trim()); inside the nested loops? Are you planning on changing div while the image processing is going on? or are you just looking for ways to make it extremely slow?

What does this mean?
Are you getting an exception?
Does it do something you do not expect?
Have you single stepped, to see what value div is set to in your code?
What, which, something else?
BTW there are several articles here on CP that demonstrate converting to greyscale, have you looked at them.

Thanks both
problem solved i was not handling exception and not i placed that code outside of the loops as follow
public Bitmap GrayScale(Bitmap bmpimg)
{
BitmapData bmpData = bmpimg.LockBits(new Rectangle(0, 0, bmpimg.Width, bmpimg.Height), ImageLockMode.ReadWrite, PixelFormat.Format24bppRgb);
int remain = bmpData.Stride - bmpData.Width * 3;
unsafe
{
byte* ptr = (byte*)bmpData.Scan0;
int div = 1;
try
{
div = Convert.ToInt32(textBox1.Text.Trim());
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
for (int i = 0; i < bmpData.Height; i++)
{
for (int j = 0; j < bmpData.Width; j++)
{
ptr[0] = ptr[1] = ptr[2] = (byte)((ptr[0] + ptr[1] + ptr[2]) / div);
ptr += 3;
}
ptr += remain;
}
}
bmpimg.UnlockBits(bmpData);
return bmpimg;
}
