Okay big brains here's something that's more of a challenge than a requirement. I am a bit stumped. I usually just need a prod in the right direction, so get your prodding sticks ready. I have a tabcontrol covered in textboxes. I want to perform a check of the contents of all the textboxes during the SelectedIndexChanged event on a list...
In Ruby, what is the most expressive way to map an array in such a way that certain elements are modified and the others left untouched? This is a straight-forward way to do it: old_a = ["a", "b", "c"] # ["a", "b", "c"] new_a = old_a.map { |x| (x=="b" ? x+"!" : x) } # ["a", "b!", "c"] Omitting the "leave-alon...
It's pretty common - especially as you try to make your code become more data-driven - to need to iterate over associated collections. For instance, I just finished writing a piece of code that looks like this: string[] entTypes = {"DOC", "CON", "BAL"}; string[] dateFields = {"DocDate", "ConUserDate", "BalDate"}; Debug.Assert(entTypes....
I would like to know the iteration order for the Array, Dictionary and Object types in AS3, for both the for-each and the for-in loops. Also what factors can change the iteration order of these loop type combinations? For example I presume that using a for-each on an Array type always move from the first element to the last. For-each ca...
Example code: int a[] = new double[]{0, 1, 2, 3}; int result = 0; for (int i : a) result += i; Is the loop guaranteed to iterate across a[0], a[1], a[2], a[3] in that order? I strongly believe the answer is yes, but this page seems to not unambiguously state order. Got a solid reference? ...
hi, i have an object which represents a database table. I want to iterate through this object and print printing each value. What can i use to do this? i want to do this inside my mxml not actionscript for each object attribute i want to create an imput field ...
Say you have a javascript object like this: var data = { Name: 'Property Name', Value: '0' }; You can access the properties by the property name: var name = data.Name; var value = data["Value"]; But is it possible to get these values if you don't know the name of the properties? Does the unordered nature of these properties make it...
#define IMGX 8192 #define IMGY 8192 int red_freq[256]; char img[IMGY][IMGX][3]; main(){ int i, j; long long total; long long redness; for (i = 0; i < 256; i++) red_freq[i] = 0; for (i = 0; i < IMGY; i++) for (j = 0; j < IMGX; j++) red_freq[img[i][j][0]] += 1; total = 0; for (i = 0; i < 256; i++) to...
In Team foundation server I use Iterations / Areas. However when I run queries and select Iteration path as a column it always contains the 'root' iteration i.e. the name of the project. Is there a way how to get rid of it? It takes so much space (I unwisely chose long project name) and adds no extra information. ...
I have the following data that looks like this for example: 34 foo 34 bar 34 qux 62 foo1 62 qux 78 qux These are sorted based on the first column. What I want to do is to process lines that starts with 34, but I also want the file iteration to quit after it finds no more 34s, without having have to scan through whole f...
I need to access the current and previous element in an IQueryable object. If I had an int array, I would do the following: var array = new int[]{0,1,2,3,4}; for(var i = 1; i<array.Length ; i++) { method1(array[i-1], array[i]); } I don't know to do the same with IQueryable, since it does not implement IList. ...
Given multiple (x,y) ordered pairs, I want to compare distances between each one of them. So pretend I have a list of ordered pairs: pairs = [a,b,c,d,e,f] I have a function that takes two ordered pairs and find the distance between them: def distance(a,b): from math import sqrt as sqrt from math import pow as pow d1 = pow...
i have a form and would like to give users the ability to duplicate a group of fields as many times as necessary. With one group it iterates correctly but when I add a second group the "current" variable iterates collectively instead of being unique to each group... i tried changing all of the "current" to "newFieldset.current" but that ...
Okay I have to write a program that accepts 2 or more arguments and searches the second and remaining arguments for a matching argument. for example the output would be: ./a 3 h 4 9 3 3 found or ./a hsi and iash me 34 hsi hsi found So far I have this, and I'm pretty sure I've got a lot of junk in here that is useless in the...
How do I process the elements of a sequence in batches, idiomatically? For example, with the sequence "abcdef" and a batch size of 2, I would like to do something like the following: for x, y in "abcdef": print "%s%s\n" % (x, y) ab cd ef Of course, this doesn't work because it is expecting a single element from the list which its...
I want to make the results of a foreach loop into a string variable I can use later all over (so I don't need to paste the foreach loop everywhere). I have this: foreach($pairs as $d=>$m) { $orderedpairs .= "[".$d."],[".$m."]"+"<br />"; } echo $orderedpairs; If I substitute the assignment operator with "echo", it works fine, so the lo...
The question field is a bit too short to pose my real question. If anyone can recapitulate it better, please feel free. My real question is this: I'm reading a lot of other people's code in C# these days, and I have noticed that one particular form of iteration is widely spread, (see in code). My first question is: Are all these iter...
I want to iterate through records returned from a MySQL database using Perl, but only ten records at a time. The reason is that the server component can only handle 10 items per request. For example: If the query returned 35 records then I have to send the data in 4 requests: Request # # of Records -------- ...
I am learning Ruby and thought of making a Binary->Decimal converter. It gets a binary string and converts to decimal equivalent. Is there a way to keep track of the current iteration step in ruby so that the variable 'x' can be removed? def convert(binary_string) decimal_equivalent = 0 x=0 binary_string.reverse.each_char...
I've been programming in dozens of languages for 20 years but I could never understand how "FOR" work in windows cmd shell batch file, no matter how hard I tried.
