logic

问题 I am working on a logic of correcting width, height and angle of page(image). Point r1,r2,r3 are on correct image and Point d1,d2,d3 are corresponding points on current image. I have tried multiple approach and have landed on this. public System.Drawing.Bitmap CorrectFileDimentionsV2(System.Drawing.Bitmap bitmap, PagePoints pagePoints) { BitmapHelper bitmapHelper = new BitmapHelper(); var bitmapImage = bitmapHelper.Bitmap2BitmapImage(bitmap); DrawingVisual MyPath = new DrawingVisual(); using

问题 I'm trying to write a function that'll convert an integer to a string like this, but I can't figure out the logic... :( 1 = a 5 = e 27 = aa 28 = ab etc... Can anyone help? I'm really niffed that I can't wrap my head around how to write this... :( 回答1: Long list of them here: /* * Convert an integer to a string of uppercase letters (A-Z, AA-ZZ, AAA-ZZZ, etc.) */ function num2alpha($n) { for($r = ""; $n >= 0; $n = intval($n / 26) - 1) $r = chr($n%26 + 0x41) . $r; return $r; } /* * Convert a

问题 I trying to do some logic if my inputed form email matches one found in the database. How do I make the comparison if the findBy’Field” returns the whole collection instead of just the field I want to compare to? I'd think it should be done without using a foreach loop as that would kinda defeat the purpose of using my findBy method. An Example: $formEmail = $form->get('email')->getData(); existingEmail = $em->getRepository(‘UserBundle:User’)->findOneByEmail($formEmail); // or existingEmail =

问题 I need to publish the stats from my CPU, Memory and other things that are stored in a collection. The things is it need to publish only the 10 last seconds from now. I join a picture to help the understanding of this: And I coded a function but the problem is that it doesn't remove the infos that are 11sec,12sec... older than now. Meteor.publish('dockerStats', function readInfosDockerStats(timeLimitSecond) { console.log(moment(new Date()).subtract(timeLimitSecond, 'second').toDate()) return

问题 I have the following function where i hard code if conditions like 'AssignedTo','ClaimStatusId','ClaimTypeId' . So, the strCondition string has any of the values like 'AssignedTo','ClaimStatusId','ClaimTypeId' , then it will be redirected to corresponding if conditions function ChangeIDToString(strCondition,id) { if (strCondition.indexOf("AssignedTo") > -1) return GetUserName(id) else if (strCondition.indexOf("ClaimStatusId") > -1) return GetClaimStatus(id) else if (strCondition.indexOf(

问题 I'm trying to create a database to manage autobus data CREATE TABLE Company( Company_Name VARCHAR(12), Tel INT, PRIMARY KEY(Company_Name) ); CREATE TABLE Line( ID_Line VARCHAR(3), NCompany_Name VARCHAR(12), Desc TEXT, PRIMARY KEY(ID_Line, Company_Name), FOREIGN KEY (Company_Name) REFERENCES Company(Company_Name) ); CREATE TABLE Stop( ID_Stop VARCHAR(3), geoLat FLOAT(10,6), geoLong FLOAT(10,6), PRIMARY KEY(ID_Stop) ); CREATE TABLE Make( ID_Stop VARCHAR(3), ID_Line VARCHAR(3), Hour TIME,

问题 One of my exercises requires me to write a recursive method in which a list is given, and it returns the same list with only every other element on it. for example : List {"a", "b", "c"} would return List{"a","c"} I am writing in scala, and I understand that it has built in library but I am not supposed to use those. I can only use if/else, helper methods,and patterns. How could I parse thru a list using head and tail only? so far I have this: def removeLetter(list:List[String]):List[String]

问题 Using: SQL Server 2008 R2 My goal is to take a given integer (n) and select every permutation of integers with n bits in 2 columns, as below. Given: n=4 Output: ColA ColB 0 0 0 0 0 0 0 0 1 0 1 0 1 0 1 1 2 0 2 0 2 1 2 0 3 0 3 0 3 1 3 1 ... 14 1 14 1 14 1 14 0 15 1 15 1 15 1 15 1 The output does not , repeat does NOT, need to be ordered, which may or may not make this easier. I do, however, need to be able to set n to any integer... but for the sake of runtime, let's say it'll be under 10.

问题 I am new to database design and I'm trying to get into the best practices early. So far everywhere I look their seems to be an agreement that you "Create the table names at the start of development, and insert your data, do not use variables for table names. Well I was looking to make an asset management system and I can't get past what seems like a design flaw. This software would be very similar to "quickbase" if you're familiar. Here is the scenario. User can create accounts, each account
