These two will give you an Array not an ArrayList.
Correction: This does return an ArrayList NOT an Array.
From the SSCLI:
public virtual Object Clone()
{
ArrayList la = new ArrayList(_size);
la._size = _size;
la._version = _version;
Array.Copy(_items, 0, la._items, 0, _size);
return la;

Apologies for the glaring mistake in my first reply.

Hi,
I'm new to this Pocket Pc and .net stuff..., so some silly questions...
Which Pocket PC OS has already installed the .net compact framework ?
It's possible to install the .net compact framework in older versions of Pocket Pc OS ?
I had only made some tests with Embedded VC++... and that was quite disappointing... it's .net compact framework and VStudio 2003 quite better ?
Thanks in advance, greetings

I would like to send plain text data to a user specified ethernet address. I know how to send data to a specified hostname or ip address, but I must use the mac address for the app I am working on. Is there a .net object that ca do this or someone can point me to an example using dll import?

If you already know .NET very well then go ahead register at Prometric.com[^]
If you don't know .NET and read the books and practice, practice, practice and practice.

It seems that I and at least a few other people are slightly disappointed that UGLY has ended up excluding the .NEW Framework. If anyone is interested in participating in a similar .NET focused project (we could call it CUTE: .net Components for graphical User inTErfaces). Let me know and I will appraoch Chris accordingly.
I realise that currently the end user market is fairly limited (compared to Win32) for .NET components, but it will grow, especially with more and more good UI components to play with.
It would also unify developers using different languages (thus preventing the VB/C++/C# debate) without having to support multiple code-bases. The source lanaguage doesn't matter as long as it's managed (CLR-compliant). And after all, the Code Project is "Your Visual Studio .NET Homepage"

I thought the idea of the CPP Group Projects was to get a decent number of people involved in a large project, like a decent extension library for .NET, to fill the gap between what we really need and what Microsoft provide.

Please help.
Where I can get a ToolBar for my Windows.Forms Application.
That toolbar should look like the toolbar in Visual Studio.
It should be able to move and dock to other sides of window.
Is there smth like that anywhere?

Hi,
I've started writing a program using version 1.0 of the framework, but now I would like to install version 1.1 and start using that. Do I need to do anything special with my application in order to get it to use version 1.1 of the framework instead of version 1.0 ?
Thanks

Depends on what tool you will be using to compile your app:
1. If you are using Visual Studio 2003, apps automatically use .Net Framework 1.1
2. If you are using Visual Studio 2002, then you have to create a config file. The config filename should be yourappname.exe.config, the location of the config file must be the same as the app's executable and the config file should contain the following lines:
<configuration>
<startup>
<requiredRuntime version="v1.1.4322" />
</startup>
</configuration>

Can some tell me where should I look to find differences between .NET 1.0 and .NET 1.1 ?
Thanks

I may be going slightly insane, but I have just installed VS.NET 2003 side-by side with my VS.NET 2002 installation.
I have compiled my remoting applications with VS.NET 2003 and they compile and (apparently) run fine -- but when I do System.Runtime.Remoting.RemotingConfiguration.Configure("server.exe.config") I get an exception informing me that there is malformed XML near the </configuration> tag.
I even tried putting a standard XML header in there but nothing changed.
Exactly the same config file works fine for the same code compiled under net1.0.
Am I doing something wrong, or has my mind finally cracked?
I'm going to sit in the corner and cry until someone helps me.

I am currently prototyping an application that will support plugin extensibility.
I figured this would be easiest achieved by allowing assemblies to be dumped in the application's directory and then having my application enumerate all the classes in those assemblies that support the IMyPlugin interface.
So far so good.
The problem I am having is in the instantiation of those IMyPlugin supporting classes.
None of these classes have a parameterless constructor because they must be provied with at least an identifying GUID when they are instantiated. I thought the following code would allow me to create one of these objects using the Activator.CreateInstance(a,t,p()) method.
However, I am having a hickup ... I get an exception at the Activator.CreateInstance line
"[System.MissingMethodException] Constructor on type MyDemo.Plugins.BasicPlugin not found"
Here is the code ...
---------------------------------
Namespace MyDemo.Plugins
Public Class BasicPlugin
Implements IPlugin
Public Sub New(ByVal guid As System.Guid)
MyBase.New(guid )
End Sub
...
End Class
End Namespace
... And in another class this function tried to instantiate it ...
Public Function NewPlugin(ByVal pluginAssembly As String, ByVal pluginType As String) As IMyPlugin
' These are the parameters to pass to the tasklet constructor.
Dim constructorArgs As Object() = New Object() {_GUID}
' Instantiate the tasklet class.
Dim myDynamicallyLoadedPlugin As Object = Activator.CreateInstance(pluginAssembly, pluginType, constructorArgs).Unwrap()
' Cast the tasklet object to a Task type.
Return CType(myDynamicallyLoadedPlugin , IMyPlugIn)
End Function
---------------------------------
I would really appreciate any suggestions that help me resolve this. In the meantime I have added a static "factory" method to the BasicPlugIn class that creates returns a new BasicPlugIn object, but this is not as ellegant and I am feeling quite defeated.
TIA

I am looking for suggestions on how to do something described below:
- a web service that will be called by a web application about 200,000 times in a 15-minutes interval.
- Each call will generate a string of data that needed to be recorded to the central database.
Someone suggested to me:
- the data generated by each call should temporary be sitting in memory.
- A timer should wake up periodically to push the data to a queue, before the memory is too full.
- The queue will write the data to the central database at a daily scheduled time.
I would like to get some idea of what technique / technology that I can use to implement those suggestion., and to make the web service efficient.
I am new to .NET and MS technology. I hope that someone can just point me to some directions and will be very much appreicate.
Thanks.

200,000 times in 15 minute intervals? Are you sure you really need to use a webservice for that? That is 200,000 HTTP requests and responses. Plus all the SOAP packaging, serialisation of the data, deserialisation, authenticating... At the least I know one IIS box is not going to come anywhere near handling that. You could optimise the data factory to hell and back but it is the IIS and webservice part that will tank.
Why does it have to be 200,000 transactions? Can you not send more data with fewer transactions?
I just think that no amount of in-memory storage, "queuing of memory" etc. ideas will help. The database could handle the writes easily enough, but not IIS.
Maybe you can explain what you are trying to do and we can come up with a better architecture and set of technologies for this

Actually 200,000/15 minutes is the total hits in the peak time of the day for a farm of 6-7 servers.
We are a brokeage firm that offers on-line quotes to clients. We would like to log the usage.

That is better. Also I misunderstood you originally, I thought you meant every 15 minutes you get 200,000 requests. Not 200,000 per 15 minutes

Ok. Well if I think of anything I will post.

What if you use a message queue through, say, MTS; the webservice creates a message on the queue, then forgets about it. You could create a service somewhere else that listens for messages on the queue and processes them accordingly.

I feel you can use the MSMQ of Microsoft.. to log into it.. (From the webservice)..Now write a bunch of message handlers..(exes /windows service) that keep pulling out messages from the queue and write into DB..
This might work.
