Yes, but that's not entirely what I want. I want a derivable singleton. The base class is a singleton*, and any derived classes must also be singletons.
* Using a loose definition of "singleton", that considers a class with only static members as the zeroth instance.

Hi All,
I have a routine i'm working on that parses a file looking for chunk information. There are various possible chunks and some chunk types (that I have defined as structs) can sometimes occur more than once in any given file.
What is the best solution for having a single collection that can hold all/any of these created structs? Can I define a generic collection like:
List<Object> _wavinfo = new List<Object>();
I've not worked like this before, would be good to know if this is a sound idea or if there is a better method. Would it be better to have a strict definition of the object I know will only be created once and List<T> for the object I know might occur more than once?
I'm basically trying to keep the memory footprint as low as possible.
Cheers,
Jammer

List<object> works fine for that.
But using classes (rather than structs) with a common base class may be somewhat better.

You probably needn't worry about that.

Hi,
Gotca, thanks for that, I started progressing with a List<object>. The problem is the similarity between these chunks is limited to just the ID of each chunk, after that they are all completely different in structure making a base class tiny. Or am I missing the point?

Then stick with the List<object> unless you think someone may put something else in the List.
It kinda depends on what you need to do with the things.

How do I change the text of a window? I read the article regarding Window Tabifier and tried using the code. However, this produced read-only results.
Thanks in advance.

You can use SetWindowText Function[^] You will need some P/Invoke to get it working, I'm sure www.pinvoke.net has some examples.

Yes, the class I used in that application has read only properties. You can however extend it for your needs.

Thanks, I went on pinvoke.net, but what should I set as the value of IntPtr?
Thanks.

You should pass handle of the window for which you want to change text.

I made a pretty easy loop but this loop runs 4 billion times this takes about 90 minutes to complete.
Now i would love to use my dual core and make it go faster!
Now my question how do i do this?
I can divide my loop in 2 and left loop1 do 1-50% and loop2 do 50-100%,
If i run this in 2 threads will that work?
Or do i need some other kind of code?
Also do i need threads or will background workers do?
Thanks!

It depends on what you are trying to accomplish. What operation is happening in the loop?
background workers are threads.

Im changing some bytes in a buffer, then preform a calculation with the buffer.
|
|
|
|

If you're not IO bound (ie the bottleneck is reading from the HD or copying the buffer from ram to cpu cache) splitting it in half and having 2 threads work at once would give a good speedup. If the modification/calculations are trivial though you're probably IO bound not CPU bound.
You know, every time I tried to win a bar-bet about being able to count to 1000 using my fingers I always got punched out when I reached 4....

I don't know if this is even possible, but I am looking for a way to programmatically tell whether a tablet is connected to the network wirelessly or is it connected to the network using a network cable plugged in. All the ways I've found just say whether it's connected or not and doesn't tell how it is connected.
Thanks for any help

System.Net.NetworkInformation.NetworkInterfaceType contains that info. Look in the System.Net.NetworkInformation namespace on how to access that information.

Thanks, that's exactly what I was looking for.

I have created an 'grid' of text boxes 17 (rows) by 20 (columns) within a groupbox.
This is like using a conrtol array in VB6.
I gave each a unique name e.g. txtboxR08C12 (row 8 column 12)
Just prior to adding the control to the group box I added an EventHandler to the textbox.
How can I identify in the EventHandler exactly which of the textboxes (preferably by name). So that I can amend the background colour and the contents to reflect a count (determined elsewhere in my code and stored in an array)

spd69,
The standard event param syntax is:
Event(object sender, EventArgs e);
Sender is the object which has raised the event, so in your case, it would be the textbox.
Regards,
Gareth.
