structure

问题 Hi I’m currently working on a project for a videocoacher program for recording and replaying video, as well as showing delayed real-time video, and tracking placement via color. The software is running on linux , on a 4 core odroid, and initially I started to make it multi threaded with threads implemented as a part of each new class. Each of these threads taking care of their own gui elements. I’ve later found out that I need to show all gui elements/video in the main/gui thread. Earlier I

问题 How can i keep the structure like this, if the tickValue is static? public float GetMoneyPerSec() { float tick = 0; foreach (UpgradeManager item in items) { tick += item.tickValue; } return tick; } 回答1: This error means your UpgradeManager looks as follows public class UpgradeManager { public static float tickValue; } remove the static keyword and it will work in the context you have in your question. If you want to use it in a static context you need to access it as follows, but then you can

问题 Closed . This question needs details or clarity. It is not currently accepting answers. Want to improve this question? Add details and clarify the problem by editing this post. Closed 5 years ago . I've been stuck on this topic for awhile now, so any guidance would be appreciated. Here's the setup: User A is following user B, but not user C. User B reshares a post from user C. The reshared post now shows up in user A's feed as the original post from user C and reshared by user B. Really

问题 It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form.

I am working on a CMS currently and it's going to have a fair amount of user input and I am starting to think about all the separate PHP scripts I am going to have. Is that normal? Can I shrink all these files

问题 In a code I accidentally used list* Head = malloc(sizeof(list*)); instead of the correct list* Head = malloc(sizeof(list)); to create a new list type node but it worked just fine later on. So my question is why did it work properly? 回答1: The idea here is, malloc() has no idea (type/size) or relation to the variable to which the return value is going to be assigned. It takes the input argument, allocates memory of the requested size and returns a pointer to the memory block, that's it. So, in

问题 So I came across this: mysite/ manage.py mysite/ __init__.py settings.py urls.py wsgi.py and this: root --+---> child1 +---> child2 --+--> subchild1 | +--> subchild2 +---> child3 and was wondering what tool(editor packages/bundle etc) does one use in order to outline and edit such structures easily/programmatically. PS: My preference is towards emacs but for the sake of completeness I will appreciate if other editors/tools were included in the answer. 回答1: The second example is clearly more

问题 Can anyone please tell me what is the problem with this code? There is no issue in the compilation of this code but after compilation when I enter the data of Array of Objects of structure, the data is not entered after one loop. #include<stdio.h> struct process{ char name; int arv; int burst; }p[10]; int sort(struct process p[],int n){ int i,j; struct process t; for(i=0;i<n;i++){ for(j=0;j<n-1-i;j++){ if(p[j].arv>p[j+1].arv){ p[j]=t; p[j]=p[j+1]; p[j+1]=t; } } } return 0; } int main(){ int i

问题 I have a question in initializing my structure array inside a structure array. for example if I have a code as below: #include <stdio.h> int main() { typedef struct { int a; int b; int c; } FIRST_T; typedef struct { int x; int y; int z; FIRST_T *p; } SECOND_T; FIRST_T p1[]={{1,2,3},{3,4,5},{6,7,8}}; FIRST_T p2[]={{4,5,6},{7,8,9}}; SECOND_T my_second[]= { {1,2,3,p1}, {4,5,6,p2} }; } if I have to initialize my first array in second array intialization part itself, then how would I write my

问题 I am traying to cast a pointer to a generic structure (blittable). It all seems fine when I am doing with non-generic structures => then I am able to use Marshal.PtrToStructure(...) but that function does not receive generic structures (Why ?) So I wrote the following: public static object ReadValue<T>(IntPtr ptr) where T : struct { var dm = new DynamicMethod("$", typeof(T), Type.EmptyTypes); ILGenerator il = dm.GetILGenerator(); il.Emit(OpCodes.Ldc_I4, ptr.ToInt32()); il.Emit(OpCodes.Ldobj,

问题 First of all, I am not aiming for a specific development answer, but rather a development approach. The problem that I am having, is I have a client with a enormous amount of articles in PDFs, about 150 articles in fifty pdfs per year for the last 20 years. All of these PDFs are compiled from Quark express, from people with macs (if that info matters). Every time a new pdf magazine is created, the web-development team copy and pastes (!) each article into a form on the internet (!), incl.
