A ReaderWriterLock should do the trick, unless a Mutex is something you wanted to avoid.

I need some Help in flash with actionscript 2, im having some troubles making the screen follow the instance name "player" without using a vcam, i don't want to use a vcam because they just seem to bug out on me a lot, any reply would be awesome thanks!

[QUOTE=noctune9;25685244]In C#, I'm having a List with a lot of objects on. I have several threads iterating over the list, but I occasionally need to remove objects from the list, preferably in another thread. Can I in any way make it thread safe for multiple threads to iterate over and occasionally remove elements?

Or should I use a database? MSSQL would be the obvious choice for C#, but I'd like it to be as cross-compatible as possible, so is MySQL a good alternative for C#?[/QUOTE]
MySQL works well with C#, there's a connector on the MySQL Website. (.NET lib)

[JLea]

very dumb math question, I'm trying to get a value based on the players speed, and apply that to another value

on the value I have 0 to 1, and the speed is 0 to 200. So if the player is at 100 (half speed), the value is 0.5.

[quote] float speed = player->GetLocalVelocity().Length2D(); //between 0 and 200

float amount = 0.0 += ///WHAT GOES HERE?

viewmodel->SetPoseParameter("move_x", amount); //this is the final value (between 0 and 1 )[/quote]

[B]edit:[/B] ugh, I just have to divide it by the maximum. fuck my stupid brain

[ShaunOfTheLive]

I'm not exactly sure of your question, but do you want

float amount = float(speed) / 200

?

[b]edit:[/b] actually you don't even have to cast to float, speed is a float, I'm an idiot too (or I've been working in PHP too long)

[JLea]

yeah, I just realised that :v:

I'm using C# and MySQL on a production site, works fine.

You might also want to look into DbLinq, which provides Linq to MySQL.

In a CSharp class ("BaseClass") I've overloaded the <<= operator like this:
[csharp]public static BaseClass operator <<( BaseClass me, SomeClass you )
{
// shit happens
return me;
}[/csharp]
So I can do:
[csharp]BaseClass a = new BaseClass();
a <<= bluh;[/csharp]
But if I have a class that extends "BaseClass", when I try:
[csharp]ExtendingClass b = new ExtendingClass();
b <<= bluh;[/csharp]
I get an illegal implicit conversion from "BaseClass" to "ExtendingClass" because the overloaded operator returns a BaseClass! How can I let classes which extend BaseClass use the <<= operator?

They're not inheriting it because it's a static member, probably. It would've helped if you gave us the exact error, but that seems like it.

[QUOTE=gparent;25700734]They're not inheriting it because it's a static member, probably. It would've helped if you gave us the exact error, but that seems like it.[/QUOTE]

It is picking it up and trying to use the overload due to the error. Since the overload returns a BaseClass, and it is trying to directly assign that to the ExtendingClass instance, I get an illegal implicit conversion error.

I'm now using += but still the same issue.

[editline]28th October 2010[/editline]

I don't want to have to re-overload it for every extending class.

Still, it helps when you point out the exact error (Error code!) I did misread that though. Never overloaded operators in C# cause I've never had to, so can't help too much.

It's a compiler error (won't let me compile until it is resolved), can't see the error code anywhere.

[editline]28th October 2010[/editline]

For now I've had to make a special handler class which handles the +=, using:
[csharp]a.Handler += bluh;[/csharp]

Looks nicer in context:
[csharp]loops[ 2 ].Effects += new Echo( this ){ Fade = 0.9, Delay = 0.25 };[/csharp]

You can only overload left shift in C# if the second operand is an int, same for right shift too.

[Robert64]

[QUOTE=raBBish;25702025]You can only overload left shift in C# if the second operand is an int, same for right shift too.[/QUOTE]

I realized that, hence why I use += now.
But that wasn't the cause of the original problem.

[QUOTE=raBBish;25702025]You can only overload left shift in C# if the second operand is an int, same for right shift too.[/QUOTE]

That's weird, I wonder why it doesn't want to allow creation of operators like the stream-in and stream-out of C++.

[QUOTE=esalaka;25702787]That's weird, I wonder why it doesn't want to allow creation of operators like the stream-in and stream-out of C++.[/QUOTE]

[quote]Use operator overloading in cases where it is immediately obvious what the result of the operation will be. For example, it makes sense to be able to subtract one Time value from another Time value and get a TimeSpan. However, it is not appropriate to use the or operator to create the union of two database queries, [b]or to use shift to write to a stream[/b].[/quote]

Not that it matters too much now, but generally it starts by "CS" and is very obvious.

I bought the game so I have all of those files, this one has some added features that I'd like but they don't have any compiled binaries with those features included.

[Richy13]

in that case open the .sln and click build in visual studio and tell us what errors you get

Download, install and run CMake like the instructions tell. This will generate you a .sln

Does anyone know where I can find binaries for libev on Windows, or perhaps how I could build it myself?

I'm trying to get Manos de Mono running on Windows, and apparently it requires libev to work.

[a2h]

In C#, I have a method with a whole bunch of lambdas, like so:

[cpp] // Previewing!
menuItem.DropDownItems.Add(Str._(Str.MenuItemBrowser), null,
new EventHandler((sender2, e2) =>
{
CloudAppItem senderItem = (CloudAppItem)((ToolStripMenuItem)sender2).OwnerItem.Tag;
System.Diagnostics.Process.Start(senderItem.Url);
}));
menuItem.DropDownItems.Add(new ToolStripSeparator());

// Convenient URL grabbing
menuItem.DropDownItems.Add(Str._(Str.MenuItemCopyPrimary), null,
new EventHandler((sender2, e2) =>
{
CloudAppItem senderItem = (CloudAppItem)((ToolStripMenuItem)sender2).OwnerItem.Tag;
Clipboard.SetText(senderItem.Url);
}));

// Convenient (re)direct URL grabbing
if (item.ItemType != CloudAppItemType.Bookmark)
{
menuItem.DropDownItems.Add(Str._(Str.MenuItemCopyContent), null,
new EventHandler((sender2, e2) =>
{
CloudAppItem senderItem = (CloudAppItem)((ToolStripMenuItem)sender2).OwnerItem.Tag;
Clipboard.SetText(senderItem.ContentUrl);
}));
}
else
{
menuItem.DropDownItems.Add(Str._(Str.MenuItemCopyRedirect), null,
new EventHandler((sender2, e2) =>
{
CloudAppItem senderItem = (CloudAppItem)((ToolStripMenuItem)sender2).OwnerItem.Tag;
Clipboard.SetText(senderItem.RedirectUrl);
}));
}[/cpp]

Rinse, repeat.

While I can understand what the code does it's not exactly the prettiest thing to look at.

Turb looked at the code and gave me this:

[cpp] void clickyshit(object sender, EventArgs e)
{
CloudAppItem senderItem = (CloudAppItem)((ToolStripMenuItem)sender).OwnerItem.Tag;
System.Diagnostics.Process.Start(senderItem.Url);
}[/cpp]

[cpp] // Previewing!
menuItem.DropDownItems.Add(Str._(Str.MenuItemBrowser), null, clickyshit);
menuItem.DropDownItems.Add(new ToolStripSeparator());

// Convenient URL grabbing
menuItem.DropDownItems.Add(Str._(Str.MenuItemCopyPrimary), null, clickyshit);

// Convenient (re)direct URL grabbing
if (item.ItemType != CloudAppItemType.Bookmark)
menuItem.DropDownItems.Add(Str._(Str.MenuItemCopyContent), null, clickyshit);
else
menuItem.DropDownItems.Add(Str._(Str.MenuItemCopyRedirect), null, clickyshit);[/cpp]

He tells me I can figure it out for myself, and it has to do with sender. Does that mean a switch with things like "case Str._(Str.blahblahblah)"?

[Siemens]

No, when a WinForms control fires an event it does something along the lines of:

[csharp]
if(SomeEvent != null)
SomeEvent(this, /* event args */);
[/csharp]

So you can use the 'sender' parameter to figure out what control fired the event.
