Should the thread be spun off in the constructor?
And why have the constructor protected rather than private?
|
|
|
|
|
"protected" is how Microsoft showed the singleton pattern on MSDN
|
|
|
|
|
I bet they didn't seal it though.

A static constructor/method/property cannot access any non-static members in its class; that includes both data members and code members (constructors/methods/properties).
==> make MessageWorker() a static method.

This[^] seems to suggest it isn't; and I wouldn't make the queue neither static nor singleton myself, however it was my attempt to answer the question in general, allowing the OP to get the code to compile.

My original intent in creating the message queue as a singleton was purely for good design. Now I'll rework the class and simply ensure that the class isn't instantiated more than once.

Most often when I create a class, even when I only need one instance of it right away, sooner or later a bigger app will want to have more than one instance, so static and singleton aren't the right approach then. It is very seldom you can be sure you will never want more than one instance of anything.
In your case, whatever you have now, you may end up wanting it all duplicated:another queue, another bunch of threads filling the queue, another backgroundworker emptying the queue. So why build in that restriction in the first place?

I agree with Luc. Singletons are rarely a good design.

I just need a quick answer to this question.
If I have a custom class that implements IDisposable, in my void Dispose(){}; function whats supposed to go in there? Do I null all the resources I am using?
Any help would be appreciated.

There are many good articles at codeproject about the IDisposable pattern. I strongly suggest you read them

Whatever you want; it doesn't need to do anything if there's nothing to do.
I tend to empty collections there.

I think nothing...  Just asked us before starting anything.. .

I think you need to read books on C# before you start. Reading and passing XML data to procedure is pretty easy. Just need basic knowledge on Database types and create XML.
For quick knowledge, you might consider Linq to XML. Its the easiest.

Hi there.
I am a beginner at MVP & one question strikes my mind:
isn't it simpler to create methods in Presenter, such as:
Save()
Start()
Stop()
and possible some events to which some view may subscribe.
instead of events in IView interface:
event SavePressed
event StartPressed
event StopPressed
and some methods which a presenter can call.
In this case Presenter is still separated from View level and capable of unit testing.
But also we eliminate the necessity to create IView interface and Presenter doesn't know anything about IView (explicitly, implicitly perhaps it will have to provide dome events such as StateChanged and so on).
thanks,
Ayrat

1. Put a File Upload control on your aspx page
2. When the user submits the page, save the selected file on the server.
3. In the postback code, create an image that points to the file you saved in step 2.

Hi folks!
I have a Windows CE 5.0 device (Barcodereader with arm cpu) with WiFi.
I use .Net 3.5 on the CE and the PC.
VS2008 is the development environment.
I want to write a small program for CE which will read a barcode and an item count entry and send it to PC where the current (focused) app should receive a string like manual entry with the data.
First idea was remoting
CE does not support it.
Next idea is a WebService which works but I found no way to use SendKeys from within the WebService.
Is anybody out there with a solution or even with a better idea?

You cannot use SendKeys in a WebService. Services run under a different Desktop than what the user can see at the console.
You're CE app should be talking to a WebService that interacts with a database that your app and the normal app that the desktop is using interact with.
