hi. I need to implement some kind table-like data structure that stores info like this in Java: +--------+-------+-----+ | sij | i | j | +--------+-------+-----+ | 45 | 5 | 7 | +--------+-------+-----+ | 33 | 1 | 6 | +--------+-------+-----+ | 31 | 0 | 9 | +--------+-------+-----+ | 12 | 8...
When trying to compile the following code, I am getting a warning that line 18 makes integer from pointer without cast and that 19 and 20 are incompatible types in assignment. I am new to structures in C, and can't seem to figure out what is wrong. #include <stdio.h> struct song { char title[70]; }; struct playlist { stru...
Hi, I want to marshal a structure for use with P/Invoke, but this struct contains a field that is only relevant to my managed code, so I don't want it to be marshaled since it doesn't belong in the native structure. Is it even possible ? I was looking for an attribute similar to NonSerialized for serialization, but it doesn't seem to ex...
Hi, I am working on a project that organizes the structure and hierarchy of departments. I want to view and display the whole structure of the organization visually, but I am stuck. I wanted to know what is the best way to do it in ASP.net 3.5; my goal is to achieve something like this by code and each node is linkable and can have CSS. ...
Write a program to access the function "foo" using the structure structure2. typedef struct { int *a; char (*fptr)(char*); }structure1; typedef struct { int x; structure1 *ptr; }structure2; char foo(char * c) { --- --- --- } ...
I have a structure array containing fields as structure arrays of varying length. For example: 's' is a structure 'data' is a field in 's', and also a structure array itself and length(s(n).data) ~= length(s(m).data) I want to preallocate an array that takes a time stamp from every field s.data.timestamp. Is there a way to do this wi...

I have a function, which has a pointer to some structure as its argument. How can I check within this function, whether all required fields of the structure have been filled before a function call? example: //lib.c void f(X_type *x) { ... } //user.c main(){ X_type object; object.name = "I am X"; object.ID = 1; ... f(X_type &object);...
The ReportInfo is a structure. The structure works fine on one web page but I am trying to use it on another web-page. Here is where I saved the ReportInfo structure to the Session Variable Session["ReportInfo"] = reportInfo; On the other web-page, I re-created the Structure and then assign the session variable to it, like this... r...
I'm working in a team of 2 front-end developers on a web-based late-stage startup project. The site works quite well, but there's a lot of room for improvement code-wise, as the code is quite messy and disorganized. I would like to clean things up gradually by writing tests and carefully refactoring to avoid breaking anything. (Using p...
I have read many posts on this topic; among them and most recently .NET - Convert Generic Collection to Data Table. Unfortunately, all to no avail. I have a generic collection of structures : Private Structure MyStruct Dim sState as String Dim lValue as Long Dim iLayer as Integer End Structure Dim LOStates As New List(Of MyStruct) I...
Hello, I wanted to simulate a railway network where there would be stations, trains and routes connecting each station. So how do you think I should attempt to model this?? I thought of using graphs taking station as vertex and edges as routes. Also since there will be tens of trains and stations and hence hundreds of routes so should I...
Is there a historical reason or something ? I've seen quite a few times something like char foo[256]; or #define BUF_SIZE 1024. Even I do mostly only use 2^n sized buffers, mostly because I think it looks more elegant and that way I don't have to think of a specific number. But I'm not quite sure if that's the reason most people use them...
I know that I can save all my projects files into repository so deployment of new version of software become only using svn export into properly directory. But I have a feeling that it is not right way and for media files I should use some other utilities for deployment like rsync. But it is also a problem with double-side sync = I like...
Possible Duplicate: Why isnt sizeof for a struct equal to the sum of sizeof of each member? Consider the following C code: #include <stdio.h> struct employee { int id; char name[30]; }; int main() { struct employee e1; printf("%d %d %d", sizeof(e1.id), sizeof(e1.name), sizeof(e1)); return(0); } The out...
We get our data from a sensor which records and stores data like hashes. At any time it measures a few stuff like that: {:temperature => 30, :pression => 100, :recorded_at => 14:34:23} {:temperature => 30, :pression => 101, :recorded_at => 14:34:53} {:temperature => 31, :pression => 102, :recorded_at => 14:34:24} {:temperature => 30, :p...
Hi, I created an "address" structure. Each address (xx.yy.zz.mm) consists of an xx, yy, zz and mm element, all of which are ints. Each address also has a "name" element associated with it. I have an array of up to 100 addresses called "network". Here is an example of some elements in network: 186.88.1.21 Tyler 186.88.9.11 Bob 101.21.0...
Hi there.
