wow, VS2010 sounds way too complicated

Okay, after some messing around with winsock, I think I have a better understanding :D.

Anyways, is it find to do something like

                for (int i = 0; i < size; )
                {
                    len = Tcp.Client.Receive(buff, i, size-i, SocketFlags.None);
                    i += len;
                }

Basically it keeps calling receive until the entire chunk is received.

Sending streams with priorities is working :D

[QUOTE=high;23229974]So then why doesn't it block when I call send with a 50mb buffer. But it does when I call send with a 1 byte buffer after the 50mb?[/QUOTE]
Look at the documentation of send()'s return value. It doesn't necessarily send (copy into the kernel buffer) all the bytes you asked it to; the return value tells you how many bytes it accepted, and any excess will need to be passed to another send() call later.

If you try to send() 50 megabytes, it can't accept all that at once, but it accepts as much as it can, filling the kernel's send buffer. Then when you send() again immediately afterward, the buffer is full so it blocks.

It sends the entire 50mb though.

[Wyzard]

What value does send() return?

[Blade]

[QUOTE=Wyzard;23241706]What value does send() return?[/QUOTE]

send returns the 50mb and the recv on the server returns 50mb. And no it is not localhost.

[Wyzard]

Dunno then. It's within the bounds of how send() is specified to behave, but it's not what I would've expected. Are you sure the first send() call isn't blocking? How are you determining that?

[Blade]

I have it output how much it sent after the call using the return value.

[Wyzard]

I mean how you're determining whether send() blocked or not. That's not something a process can normally determine about itself, afaik.

[PvtCupcakes]

Edit: Solved it. So don't bother thinking about it. Solution at the bottom.

I've never done enums in C++, and I'm not sure how too use them properly.

I'm doing a Qt application, and Qt's enums are used like Qt::Monday, but it's part of an enum named DayOfWeek and is part of the Qt Namespace.

I tried something similar like:
[cpp]
namespace KJ
{
enum OptionKeys_String
{
FOO
};

enum OptionKeys_Bool
{
BAR
};

enum OptionKeys_Int
{
BAZ
};
};
[/cpp]

And if I try to use it as a function paramter like:
[cpp]
fooFunction(KJ::BAR);
[/cpp]

I get this error:

error: expected primary-expression before ')' token

But if I do:
[cpp]
fooFunction(KJ::OptionKeys_Bool::BAR);
[/cpp]

I get:

error: 'KJ::OptionKeys_Bool' is not a class or namespace

Somehow I've never worked with namespaces or enums in C++. :v:
I don't use C++ much, and I've just never had a need for a namespace.

[editline]10:47PM[/editline]

The fooFunction is declared this way:
[cpp]
static bool fooFunction(KJ::OptionsKey_Bool o);
[/cpp]

[editline]10:50PM[/editline]

Oh fuck it. I had an extraneous , left over when I called the function so it ended up like fooFunction(KJ::BAR,); And I didn't even notice. :colbert:

There's a timer (game_Timer) and a statusstrip (stats_StatusStrip)

Basically, a timer fills it with a letter every 800ms, and typing this letter should make it disappear. Of course, the letter does not disappears.

stats.Update(true);
}
else

// You missed. No update, no points.

// Update the labels.

What is wrong with it ?[/QUOTE]

Any idea ?

[editline]04:03PM[/editline]

letters_ListBox.Items.RemoveAt(index number); does not works. I'm guessing that's more a problem with my ListBox. I'll try by converting it to UTF (ConvertToUTF32).

Float precision might be the problem. Try checking x>0 instead of x==0.1

Just me being annoying :v:

Use y += 0.1 instead of y = y + 0.1
And you can replace your if statements with x *= -1

[NovembrDobby]

or x = -x;

[backwardspy]

or x = x - (x * 2)

I got some simple questions, I'm still learning Java, and I am reading HeadFirst Java (great book). But I still have some questions I'd like to get answered.. By people.

This method must return a result of type String

Above is the message I get for this line of code:

public String CheckYourself(String guessnumbers)

It is for a simple guessing game. I don't quite understand it, is all.

Next question:

I guy on FP let me have some pseudo-code for his abandoned ASCII Hero. Uh, how would I apply this to Java?

for i = 1 to 5
  if (fret[i] == 1 AND array[i][tick] == 0) OR (fret[i] == 0 AND  array[i][tick] == 1) then
     return 0
  endif
next
return 1

[quote]basically it checks if any of the one frets is not matching the current tick, and if so returns a 0. If everything's alright it return 1.[/quote]

You've declared the function CheckYourself with a return type of String - which means it is expected to return a String value.

[/QUOTE]
Expanding on the above answer, you're declared your function as a String type, meaning it'll return a string.
But, you have "return 0" and "return 1". 0 and 1 are integers, not strings
