Sorry for reopening this thread after this long. I've haven't really had time to fiddle around with this project for a while.

public List<ListViewItem> SaveListView(ListView LV)
{
System.Collections.Generic.List<ListViewItem> lSavedLV = new List<ListViewItem>();

for (int i = 0; (i <= animalList.Count - 1); i++)
{
lSavedLV.Add(LV.Items[i]);
}

return lSavedLV;
}

Is that a plausible solution for the saving part? Is that the way to go, if I plan to fill the ListView with such serialised data? Is this then a matching loading method:

public ListView LoadListView(List<ListViewItem> L)
{
ListView lv = new ListView();

for (int i = 0; (i <= (L.Count - 1)); i++)
{
ListViewItem lvi = new ListViewItem();
lvi = ((ListViewItem)(L[i]));
lv.Items.Add(lvi);
}

return lv;
}

Ah, it's a System.Windows.Forms.ListView. I was thinking that the .AddRange would solve it easily but there is something that I'm missing.

Just a simple one. How would I, in the most appropriate way (is there ever one), populate a ListView with a List<ListViewItem>?

Thanks in advance!

Alright. So I'll make some changes to the helper methods so that they return a List<ListViewItem> - that also seems more plausible. Wouldn't one be able to populate the ListView quite easily with such a list as well?

Thanks for the quick and great comments by the way.

Ye, Sergey, that was pretty much what I was going for. And also what those helper methods was for, but obviously that was where I went wrong, it seems. The idea was that the data would be stored in the ArrayList, in order to avoid serializing the whole ListView control.

Anyways, could you specify or give me a hint of a data layer example? So I get an idea of where I'm to be headed.

There is no actual error. Or, depending on one's viewpoint, there is. I'm unable to save a file with the current ListView data and then load it again, so to speak. The saving part seems to work, the problems lies with the loading of the saved data.

Well, this is one of the methods that are being called under one of the cases. I don't see why you don't qualify it as late binding?

public static Bird CreateBird(BirdSpecies Species)
{
Bird animalObj = null; //Unknown at this time

//Late binding
switch (Species)
{
case BirdSpecies.Eagle:
animalObj = new Eagle();
break;

case BirdSpecies.Pelican:
animalObj = new Pelican();
break;

default:
Debug.Assert(false, "To be filled.");
break;
}

//Sets category
animalObj.Category = CategoryType.Bird;

//Returns the created object
return animalObj;
}

Well, it is overridden in the base class as well. Somehow I thought this would nicely follow in a descending manner when working with polymorph and inheritance. Thanks, though. For clarifying it.

Having the input from run-time being print as name, age, cat, gender simply by calling base, instead of the second. Basically, I'm wondering why the second one works and not the first one, ought they not to work in the same way? What am I missing?

Cheers, I'll go through your articles. Thanks!

leprechauny 6-Feb-13 17:30pm View

No. It's quite necessary actually. The thing I'm after is a function like "list all types" checkbox.

leprechauny 3-Feb-13 18:41pm View

thanks a lot!

leprechauny 3-Feb-13 16:27pm View

Ye, I assumed that would be part of it. And it seems to work. However, how should I successfully bind it - as you can see the first list is called lstCategory and the second is lstAnimalType - and I can't seem to figure it out. The 'Enum.Parse' just doesn't do it for me. Any advice?

leprechauny 7-Jan-13 14:19pm View

Ah, seems good. Seems to work, however the following

resultTxt.AppendText("Port " + val[0] + " " + val[1] + "\r\n");

throws a nullrefexception

leprechauny 7-Jan-13 13:32pm View

Seems fair. Is this done by using a delegate?

leprechauny 7-Jan-13 13:31pm View

Yes, exactly. How am I going to go about to send the information from the background thread to the main thread using ProgressChanged event?

leprechauny 28-Dec-12 10:56am View

How silly of me! Cheers, Dave. Great!

I receive the uptime of the system since last reboot. And for the moment being I only get a static such. The counter doesn't go on ticking, so to speak.

leprechauny 29-Oct-12 16:41pm View

Well, as indicated and correctly assumed there are only four levels. So exactly as you suggest I think it's plausible to use an array to hold the different levels. However, the real number of sellers are six. But is that really an issue? That is, the numbers of sellers ought to be irrelevant when you determine which level has that been reached.
