Say I have a struct that looks like this (a POD):
struct Foo
{
int i;
double d;
};
What are the differences between the following two lines:
Foo* f1 = new Foo;
Foo* f2 = new Foo();
Any smart way to convert a float like this:
float f = 711989.98f;
into a decimal (or double) without loosing precision?
I've tried:
decimal d = (decimal)f;
decimal d1 = (decimal)(Math.Round(f,2));
decimal d2 = Convert.ToDecimal(f);

I have made a very simple program in C#. When I double click the compiled exe, it executes and works. When I run the exe from the command prompt, it does absolutely nothing. I have tried executing it from an Administrator command prompt also. I am on Windows 7. This is very frustrating.
The only command the program executes when ran is
SendMessageW(Process.GetCurrentProcess().MainWindowHandle, WM_APPCOMMAND, Process.GetCurrentProcess().MainWindowHandle, (IntPtr)APPCOMMAND_VOLUME_MUTE);
In many books weightx and weighty values are expressed in different ways:
some says 0.0 to 1.0
other says 0 to 100
other say until 1000
I'm a lot confused.
In the API these variables are double types so I think the first is correct but what does it meaning a value of 0.4 or 0.7? are percentage values, point values? relative of what?
int NM_Generator = 1;
//Aray to store thread handles
HANDLE Array_Of_Thread_Handles[1];
//variable to hold handle of North pulse
HANDLE Handle_Of_NM_Generator = 0;
//Create NM_Generator Thread
Handle_Of_NM_Generator = CreateThread( NULL, 0, NMGenerator, &dDifference, 0, NULL);
if ( Handle_Of_NM_Generator == NULL) ExitProcess(NM_Generator);
i want to pass a parameter double value in it how can i do so?
Hi all,
I just wanted to make a quick check,does any of you know of an open source c# code to present wave form (graphically) from a byte array?
Thank you!
Hi,
I'm using ".align 16 \n\t" in some inline ARM assembly that is implementing some loops
to align it on a 16 byte boundary however gcc asm compiler is complaining that alignement
is too large
i want to implement -falign-loops=16 in asm for a particular loop

How to sort a map(?,B) on the values in Java with google collections ordering function, if B is a class, which has a field of type double, which should be used for ordering.
I'm trying to write a regular expression that finds C#-style unescaped strings, such as
string x = @"hello
world";
The problem I'm having is how to write a rule that handles double quotes within the string correctly, like in this example
string x = @"before quote ""junk"" after quote";
This should be an easy one, right?
hello,
I'm writing a client server application, but I don't receive the same bytes at the client side when they are sent from the server side.
At the server side I used .write(bytes[]) method. At the client side, I used .readFully(byte[]) method.
Do you have any idea ?
As I remember there is a magic command line option in Java that turn on writing of operations that are currently executed to console. The output was looked like byte code. I do not mean -verbose, because it prints only class loading, while this option outputs information like memory allocation etc.
Hi All,
I need to convert the IL to c# code.
I have an assembly and I am reading this assembly.
I get MethodBody from MethodInfo and the methodbody has a method GetILAsByteArraY()
which returns a byte array now I want to comvert this IL to C# code.
Please help me out in solving this.
I am new in Prolog. I need to declare a function which looks at a list like
[[1, 0, 0], [1, 0, 0], [1, 0, 0]]
and if the value is 0 returns its address(by considering it as a double array).
I wrote a function basicly in the format:
function(..., X) :-
function(called by other values).
How can I write a function, that returns a value when each times it called(recursively). May I get them (in above question) as alternative X's???
I have a contact page on my site that seems to have been latched on to by a spammer.
The error itself is:
System.IO.EndOfStreamException: Unable to read beyond the end of the stream.
at System.IO.BinaryReader.ReadByte()
at System.Web.UI.ObjectStateFormatter.DeserializeIndexedString(SerializerBinaryReader reader, Byte token)
at System.Web.UI.ObjectStateFormatter.DeserializeValue(SerializerBinaryReader reader)
Google turns up little.
I assume they are submitting an invalid viewstate, but the exception has no line number so im stumped.
Hi I have Map of String values.
I want to cast this value at runtime.
e.g.
Map map = new HashMap();
map.put("key1","101");
map.put("key2","45.40");
Now runtime I know key1 is integer and key2 is double
How can I cast this.
I tried this:
("101").getClass().cast(Integer).
Thanks.
It says:
In general,make searches for an
implicit rule for each target[1], and for
each double-colon rule[2], that has no
commands[3].
This can have two different understanding:
1 or (2 and 3)
(1 or 2) and 3
Which does it mean?
I would like to get the absolute position of an element in relation to the window/root element when it is double clicked. The element's relative position within it's parent is all I can seem to get to, and what I'm trying to get to is the point relative to the window. I've seen solutions of how to get a the point of an element on the screen, but not in the window.
In Bash script, what is the difference between the following snippets?
1) Using single brackets:
if [ "$1" = VALUE ] ; then
# code
fi
2) Using double brackets:
if [[ "$1" = VALUE ]] ; then
# code
fi

i have a string like this
something = "something, something1, "something2, something else", something3"
i need it to be read into a table like this:
field1 = "something"
