Hello,
I have this class:
public class GameObject : ObservableCollection<Property>
{
public string Name { get; set; }
public override string ToString()
{
return Name;
}
}
Property is my own class.
When I add it to a ListBox it does not call the ToString() method but rather just shows (Collection) in the list box.
Isnt that a bug?  At least seems weird to me. I do not want to change the class heirarchy from inheritance to composition for this problem but if I do not have a choice ill do it.

Basically i need an idea of how they work exactly
Thanks in advance

I would say that if you are a beginner, it would be the best if you can start working on small project instead of trying for something that is built by Google. Why don't you try simple Data Entey Form, Form authentication and etc first?

Hi,
I am working on a silverlight application. In this I have a scroll viewer with Canvas. These two are a module in Page.xaml. In the same way I have different modules in Page.xaml. Some times I need to change the width and height of the canvas and scrolview. At that time I want to change the location of these two components dynamically.
If anyone have any idea to dynamically change the location of the controls please reply me.
Thanks in Advance.

Hi
I am wondering if anybody knows what are the hardware requirements for wpf animations to run. I googled for it but found no answers. What I really want is to programmaticaly determine if the machine(graphic card) supports animations. Any advice will be appreciated.

If it's vista, I think you can programatically check the index that Vista has for how fast your computer is, how good your card is, etc. Otherwise, I'd expect you could look into writing DirectX code that checks if aspects of DX are available, that's what we're talking about, after all.

WPF uses DirectX/Direct3D, so I reckon if you can run a WPF app,
you can use WPF animation.

Is there a way to use excel spreadsheet ***as a datagrid*** in a WPF client-server application?
I know i can use WindowsFormsHost control in a WPF client application to host a winforms WebBrowser control, however this is really not a straight forward way of doing it.
I was wondering if you would know any other way of using excel spreadsheet ***as a datagrid*** in WPF client?

You can't use FILE:// URIs from a Silverlight application because
Silverlight applications don't have direct access to local drives.

Hi guys!
Experiencing something weird recently.
Due to the fact, that my observable collection is the datacontext of my wpf app,
I need to make sure, that every Thread is able to add Elements.
Now the easy and working way is to add a
Dispatcher.Invoke(new Action(()=>{collection.Add(element})); from every method being allowed to do so, which is kind of annoying.
So I thought it would be a good idea to add the functionality to the observable collection itself.
This is what I came up with:
class MElementsCollection :ObservableCollection<MElement>
{
#region Variables
private Dispatcher mainDipatcher;
public Dispatcher MainDipatcher
{
get {
if (mainDipatcher == null)
mainDipatcher = App.MainDispatcher;
return mainDipatcher;
}
}
#endregion
public void AddThreadSafe(MElement mElement)
{
if (Thread.CurrentThread != MainDipatcher.Thread)
{
MainDipatcher.Invoke(new Action(() =>
{
this.Add(mElement);
}));
}
else
this.Add(mElement);
}
}
Now what's actually happening is, that by adding many items short one after another, not every item is added to the collection but just for example every second one.
Can anyone please help me with this?
As always,
Thank you in advance

Why not take a look at Tamir's implementation here[^]? There's no need to reinvent the wheel here.

Hi,
I am working on a silver light application. In this I need to upload videos, save them in afolder and retrieve them back to display. In this I need to save the uploaded video in a folder for retrieving later.
I came across some applications where the video is converted to bytes and saved in database and retrieved from there. But as i want the video to be saved in a folder I need to convert the byte[] in to video in a service and save itin my application folder.
If any one have any idea to directly save the slected file in the openfiledialog to a folder or to convert byte[]to video and save it in a folder, please rply me.
Thanks in advance

What part of this are you having problems with?
The System.IO Namespace[^] should have everything you need
to work with directories and files.

I've been learning c# for about 2 months now and have already made some pretty useful winform applications. With that said I feel that I have a decent understanding of c# although there is still plenty to learn. I'm at the point now where I find myself wanting to experiment with custom controls. At this point I'm not sure if I should continue to learn WinForm's or shift my focus on WPF as it seems to be the emerging tech.
Any advice would be great.
Thanks!

WPF is gaining foothold, I suspect more and more apps will use winforms in the future. Have you learned proper C#, things like different container classes, how to handle objects that are IDisposable, etc ? If not, I'd stick to winforms while learning the language a little better. Then I'd look into WPF.

i totally think you shoud turn to the WPF,as we know,some parts of the VS2010 is designed by WPF,so i think the microsoft will think highly of the WPF,and wo know the route MFC->WinForms->WPF.so we shoud learn the new tech~
sorry,my english is poor --!
