I am php learner and i am at a crossroad here, i am using simple incrementation to try to get what im asking across. I am certainly not here to start a debate about the pros/cons of referencing, but when it comes to php, ...

It there an easy way to pass all the variables a template file has access to onto a partial when I have output escaping on? I tend to create a template file, then refactor things into a partial at some point and it would seem that there would be an easy way to just pass all the same variables from the template to the partial and be done...
Does anybody know if it is possible to return an associative array as the result of an Oracle function, if so do you have any examples? I have an Oracle package which contains an associative array declaration as defined below: TYPE EVENTPARAM IS TABLE OF NUMBER INDEX BY BINARY_INTEGER; This is then used in a stored procedure ...
All, When we are passing an expression as a parameter, how does the evaluation occur? Here is a small example. This is just a pseudocode kind of example: f (x,y) { y = y+1; x = x+y; } main() { a = 2; b = 2; f(a+b, a) print a; } When accessing variable x in f, does it access the address of the temp variable which c...
I'm very new to C++ and I'm currently learning it. I got a few questions.. What is the differences between void DoSomething(const Foo& foo) and void DoSomething(Foo foo)? If we don't specify & then the instance of Foo will be passed by value ( not reference ). It will be the same as having const + & in argument except no checking at co...
I am trying to pass a coordinate, which is defined as struct with 2 integer parameters (the struct is called coord) the following way: UpdateB({0,0}); where the input argument is of type coord (i.e. in the above statement I am trying to pass a coordinate 0,0). UpdateB is some function. I am getting an error, any ideas what the probl...

Suppose I have a method like this: public void MyCoolMethod(ref bool scannerEnabled) { try { CallDangerousMethod(); } catch (FormatException exp) { try { //Disable scanner before validation. scannerEnabled = false; if (exp.Message == "FormatException") ...
Hi, I actually thought that I had a good idea of how passing values in Java actually work, since that was part of the SCJP cert which I have passed. That was until today, when I at work discovered a method like this: public void toCommand(Stringbuffer buf) { buf.append("blablabla"); } Then the caller of that method used the functi...
Hi, Does php function parameters pass as ponter to object or as copy of object? Its very clear in C++ but in php5 I don't know. Example: <?php $dom=new MyDocumentHTMLDom(); myFun($dom); ?> parameter $dom pass as pointer or as copy? Thanks ...

What my team would like is to be able to select more than one customer at a time to save time; however they want a separate page per customer_name.

Hello all, I have an exam on C++ coming up, and I'm solving a few ones from past years. I have this question in one of them: A function calculates the volume of a prysm. Arguments passed are height, depth and width. Arguments and return value are doubles Depth is optional and should default to 10. Hypothesis 1: All para...
Hi! I'm reading something about overload resolution and I found something that bothers me...In the following code: int const& MaxValue(int const& a, int const& b) { return a > b ? a : b; } void SomeFunction() { short aShort1 = 3; short aShort2 = 1; int const & r2 = MaxValue(aShort1, aShort2); // integral promotion ...

Hi, everyone I want to ask about the passing parameter in objective C on iPhone simulator. Is it possible to pass an parameter (e.g. NSArray) to the delegate method? I wrote a program, when the user press a button, it will call a function called 'pressLoginButton' (user-defined). After complete the function, I have to pass an NSArray ...
Consider the following function template: template<typename T> void Foo(T) { // ... } Pass-by-value semantics make sense if T happens to be an integral type, or at least a type that's cheap to copy. Using pass-by-[const]-reference semantics, on the other hand, makes more sense if T happens to be an expensive type to copy. Let's ass...
