Given the following sample array, how can I find all permutations of times available such that the amountNeeded is satisfied? In others words the follow array should produce the following: Available on 2008-05-14 from 08:00 to 08:10 using resource 10 and 13 Available on 2008-05-14 from 08:10 to 08:20 using resource 10 and 13 pri...
I recently ran across some 3rd party C# code which does the following: public int RecvByteDataFromPrinter(ref byte[] byteData) { byte[] recvdata = new byte[1024]; ///...fills recvdata array... byteData = recvdata; return SUCCESS; } What does the line "byteData = recvdata" actually do in this case? It appears tha...

Hi, I am pulling data out of an old-school ActiveX in the form of arrays of doubles. I don't initially know the final number of samples I will actually retrieve. What is the most efficient way to concatenate these arrays together in C# as I pull them out of the system? ...
Okay i am working on someone elses code. They do alot of this: char description[256]; description[0]=0; I know this would put a \0 in the first spot of the character array. But is this even a safe way to erase a string? Also visual studio keeps reporting memory leaks, and i've pretty much tied this done to the strings that are used. ...
I've written a Korn Shell script that sets an array the following way: set -A fruits Apple Orange Banana Strawberry but when I'm trying to run it from within cron, it raises the following error: Your "cron" job on myhost /myScript.sh produced the following output: myScript.sh: -A: bad option(s) I've tried many crontab syntax vari...
( can't believe this hasn't been asked in SO yet... ) How can I remove duplicate values from an array in PHP? ...
How can I remove duplicate values from a multi-dimensional array in PHP? Example array: Array ( [0] => Array ( [0] => abc [1] => def ) [1] => Array ( [0] => ghi [1] => jkl ) [2] => Array ( [0] => mno [1] => pql ) [3] => Array ( [0] => abc [1] => def ) [4] => Array ...
How can I initialize an const / static array of structs as clearly as possible? class SomeClass { struct MyStruct { public string label; public int id; }; const MyStruct[] MyArray = { {"a", 1} {"b", 5} {"q", 29} }; }; ...
I'm trying to transform each element of a numpy array into an array itself (say, to interpret a greyscale image as a color image). In other words: >>> my_ar = numpy.array((0,5,10)) [0, 5, 10] >>> transformed = my_fun(my_ar) # In reality, my_fun() would do something more useful array([ [ 0, 0, 0], [ 5, 10, 15], [10,...
I have a simple function in which an array is declared with size depending on the parameter which is int. void f(int n){ char a[n]; }; int main() { return 0; } This piece of code compiles fine on GNU C++, but not on MSVC 2005. I get the following compilation errors: .\main.cpp(4) : error C2057: e...
Is it advisable to use arrays in Javascript using tens of thousands of indexes? I have a database which contains a table of static data, meaning that it will never change. In this case would it be advisable to convert this table to a javascript array and look the info up in there when needed? Is this bad practice? The table in question...
I have an object that implements ArrayAccess, Iterator and Countable. That produces a nigh-perfect array masking. I can access it with offsets ($object[foo]), I can throw it into a foreach-loop, and many other things. But what I can't do is give it to the native array iterator functions (next(), reset(), current(), key()), even though I...
I have a SUM array formula that has multiple nested IF statements, making it very inefficient. My formula spans over 500 rows, but here is a simple version of it: {=SUM(IF(IF(A1:A5>A7:A11,A1:A5,A7:A11)-A13:A17>0, IF(A1:A5>A7:A11,A1:A5,A7:A11)-A13:A17,0))} As you can see, the first half of the formula checks where the array is greater t...
I ran into this bug where an element of an array, if its index is the string "0", is inaccessible. It's not a bug with unserialize, either, as this occurred in my code without invoking it. $arr = unserialize('a:1:{s:1:"0";i:5;}'); var_dump($arr["0"]); //should be 5, but is NULL var_dump($arr[0]); //maybe this would work? no. NULL ...
I had this question earlier and it was concluded it was a bug in 5.2.5. Well, it's still broken in 5.2.6, at least for me: Please let me know if it is broken or works for you: $obj = new stdClass(); $obj->{"foo"} = "bar"; $obj->{"0"} = "zero"; $arr = (array)$obj; //foo -- bar //0 -- {error: undefined index} foreach ($arr as $key=>...
Hello, I am a bit new to Perl, but here is what I want to do: my @array2d; while(<FILE>){ push(@array2d[$i], $_); } It doesn't compile since @array2d[$i] is not an array but a scalar value. How sould I declare @array2d as an array of array? Of course, I have no idea of how many rows I have. ...
I'm generating titles out of a few other fields, and want the "right" way to do: Me.Title.Value = Join(Array([Conference], [Speaker], partstr), " - ") Except any of [conference], [speaker] or partstr might be null, and I don't want the extra "-"'s. Are there any functions that'll make this job straightforward? ...
I'm a little lost (still working with Ron Jeffries's book). Here's a simple class: public class Model{ private String[] lines; public void myMethod(){ String[] newLines = new String[lines.length + 2]; for (i = 0, i <= lines.length, i++) { newLines[i] = lines[i]; } } } I have another cla...
