I know that the following is case sensitive:
if (StringA == StringB) {
So is there an operator which will compare two strings in an insensitive manner?
Hi,
I'm just wondering if anyone knows the reason why you are not allowed to use interfaces with the implicit or explicit operators?
E.g. this raises compile time error:
public static explicit operator MyPlayer(IPlayer player)
{
...
}
"user-defined conversions to or from an interface are not allowed"
Thanks,
I was doing some basic audio programming in C# using the NAudio package and I came across the following expression and I have no idea what it means, as i've never seen the << operator being used before. So what does << mean?
Please give a quick explaination of this expression.
short sample = (short)((buffer[index + 1] << 8) | buffer[index + 0]);
Usual method of applying mathematics to variables is
a * b
Is it able to calculate and manipulate two operands like this?
a = input('enter a value')
b = input('enter a value')
op = raw_input('enter a operand')
then how do i connect op and two variables a and b?? i know i can compare op to +, -, %, $ and then assign and compute....
but can i do something like a op b ,
how to tell compiler that op is an operator?? any tweaks possible?
What is the instanceof operator in JavaScript?
I saw this in a blog post by John Resig, and didn't understand what does it means in regular JavaScript code (without that library).
i need to use the like operator in a linq query
for this:
timb = time.Timbratures.Include("Anagrafica_Dipendente")
.Where(p => p.Anagrafica_Dipendente.Cognome + " " + p.Anagrafica_Dipendente.Nome like "%ci%");
How can i do?
Which method is faster or more responsive in javascript, if/else or the ternary operator? Is it preferred to use one or the other and if so, for what reasons?
I recently encountered with this question: How to reduce this expression: s73?61:60;.
The hint given was that Instead of using conditional operator we could use a simple comparison which will work fine.
I am not sure but I think it is possible with some GCC extension,although I am unable to figure it out myself.
EDIT:The whole expression is this : s-=s73?61:60
I have a query that prints userid in label1 when username is entered.Works fine; but i want to write query for username and password that prints userid. so how can i write it? i tried writing using 'and' operator but dont seems to work.

where auser.username == userNameString //&& auser.Password =pwdString
select auser.userid).SingleOrDefault();
label1.Text = id.ToString();

Hello all
Can you recommend me on places where i can read and see examples on usage of Lambda operator in c# .
I will really like to see a lot examples on it...
Thanks.
I want to add a Custom rule for avoiding the '==' operator inside a method in a class.
For example in the below method i need to avoid 'str1==str2' with string.Compare(str1, str2,StringComparison.Ordinal);.So I need to check this types of code are appear in any of the method
public void StringTest2()
{
string str1 = "Hello";
string str2 = "HELLO";
if (str1 == str2)
{
}
}
I have dom table

select * from dom where skills like '%C++,C%' i didnt get result

I need to display a piece of HTML only if a variable value appears in a list. I know that Django 1.2 has an 'in' operator. But I am working on a Google App Engine app. Is there a workaround I can use?
Are there some drawbacks of such implementation of copy-constructor?
Foo::Foo(const Foo& i_foo)
{
*this = i_foo;
}
As I remember, it was recommend in some book to call copy constructor from assignment operator and use well-known swap trick, but I don't remember, why...
What is your opinion of using the infix operator hack in production code? Issues:
The effect this will have on speed.
The potential for a clashes with an object with these operators already defined. This seems particularly dangerous with generic code that is intended to handle objects of any type.
It is a shame that this isn't built in - it really does improve readability
I want to find the greater of two numbers without using < > this relational operator.
I tried this
int a,b;
if(a/b==0)
{
b is greater
}
else
{
a is greater
}
but this not working for negative numbers.
Can anybody provide some details on <:< operator in scala.
I think
if(apple <:< fruit) //checks if apple is a subclass of fruit.
Are there any other explanations? I see many definitions in the scala source file.
I am trying to query the google datastore for something like (with pm -- persistanceManager):
String filters = "( field == 'value' || field == 'anotherValue' )";
Query query = pm.newQuery(myType.class, filters);
When I execute - I am getting back: App Engine datastore does not support operator OR.
What's the best approach in people experience for this kind of queries?
Any help appreciated!
I have simple task concerning 'new' operator. I need to create array of 10 chars and then input those chars using 'cin'. Should it look like this ? :
char c = new char[10];
for(int i=0; i < 10; i++)
{
cin >> char[i] >> endl;
}
i like to find the greatest of two nos without using < this relational operator.
i tired this
int a,b;
if(a/b==0)
{
b is greater
}
else
{
a is greater
}
but this not working for negative nos .please help for this
I'm a little confused when I see the output of following code:
$x = "a";
$y = "b";
$x ^= $y;
$y ^= $x;
$x ^= $y;
echo $x; //got b
echo $y; //got a
And I wonder how does the operator ^ work here?Explanations with clarity would be greatly appreciated!
If I have have some overloaded ostream operators, defined for library local objects, is its okay for them to go to std namespace? If I do not declare them in std namespace, then I must use using ns:: operator <<.
As a possible follow-up question, are there any operators which should go to standard or global namespace?
