arguments
Why can’t I pass constant arrays as arguments?
Short answer: You need to make use of a compound literal. Something like arrayfn( (double[]) {1.0, 2.0, 3.0} ); should do the job. Some explanation Coming to the part, why arrayfn({1.0, 2.0, 3.0}); did not work, because, without the syntax for compound literals, {1.0, 2.0, 3.0} is a brace enclosed initializer list. It does not … Read more
Pass arguments to running application
I have figured it out, so awesome thanks for the person who posted the http://social.msdn.microsoft.com/Forums/en-US/csharpgeneral/thread/a5bcfc8a-bf69-4bbc-923d-f30f9ecf5f64 link, this is exactly what I was looking for! Here’s a the full solution: static class Program { [STAThread] static void Main(params string[] Arguments) { SingleInstanceApplication.Run(new ControlPanel(), NewInstanceHandler); } public static void NewInstanceHandler(object sender, StartupNextInstanceEventArgs e) { string imageLocation = … Read more
build argument lists containing whitespace
[*] There are (at least) two ways to do this: Use an array and expand it using “${array[@]}”: bar() { local i=0 args=() for arg in “$@” do args[$i]=”prefix $arg” ((++i)) done foo “${args[@]}” } So, what have we learned? “${array[@]}” is to ${array[*]} what “$@” is to $*. Or if you do not want … Read more
Skip some arguments in a C++ function?
Not directly, but you might be able to do something with std::bind: int func(int arg1 = 0, int arg2 = 0, int arg3 = 0); // elsewhere… using std::bind; using std::placeholders::_1; auto f = bind(func, 0, _1, 0); int result = f(3); // Call func(0, 3, 0); The downside is of course that you are … Read more
Specifying arguments with spaces for running a python script
where “argument 1” is a single argument. You’ve basically answered your own question there, “argument 1” is indeed a single argument. In other words, you need to quote it, something like one of: python testProgram.py “argument 1” ‘argument 2′ This isn’t actually a Python issue however, it depends on the shell that you’re using to … Read more
Argument type for Qt signal and slot, does const reference qualifiers matters?
Qt checks a normalized signature, meaning Normalization reduces whitespace to a minimum, moves ‘const’ to the front where appropriate, removes ‘const’ from value types and replaces const references with values.
How to pass arguments into event listener function in flex/actionscript?
A function called by a listener can only have one argument, which is the event triggering it. listener:Function — The listener function that processes the event. This function must accept an Event object as its only parameter and must return nothing, as this example shows: function(evt:Event):void Source You can get around this by having the … Read more
Calling superclass constructors in python with different arguments
Other answers suggested adding self to the first parameter. But usually invocations of __init__ in parent classes are made by super. Consider this example: class A(object): def __init__(self, x): print(‘__init__ is called in A’) self.x = x class B(object): def __init__(self, *args, **kwargs): print(‘__init__ is called in B’) super(B, self).__init__(*args, **kwargs) class AB(B, A): def … Read more
method in class cannot be applied to given types
generateNumbers() expects a parameter and you aren’t passing one in! generateNumbers() also returns after it has set the first random number – seems to be some confusion about what it is trying to do.
