  • Compiled code spreadsheet-like cell management? (auto-updating)

    - by proGrammar
    Okay so I am fully aware how spreadsheets manage cells, they build dependency graphs where when one cell changes it tells all the other cells that are dependent on it that it changed. So they can from there update. How they update I think involves either re-evaluating the formulas stored as strings, or re-evaluating the abstract syntax tree which I think is stored differently and might be faster. Something like that. What I'm looking to do is manage a few variables in my code so I don't have to update them in the correct way, which would be a nightmare. But I also want it much faster than spreadsheets. And since I'm not looking for any functionality as great as are in these spreadsheets, I just figured from that thought point that there has to be a way to have a very fast implementation of this functionality. Especially since I don't have to modify cells after compiling unless that would be an option. I'm very new to programming so I have no idea. One example might be to have a code-generator that generates code that does this for me. But I have no clue what the generated code would look like. Specifically, how exactly would variables inform others that they need to update, and what do those variables do to update? I'm looking for any kind of ideas. Programming is not my job but nonetheless I was hoping to have some kind of system like this that would greatly help me with some stuff. Of course I have been programming plenty lately so I can still program. I just don't have the full scope on things. I'm looking for any kind of ideas, thank you very much in advance! Also, please help me with the tags. I know C# and Java mainly and I'm hoping to implement this in either of those languages and I'm hoping this can stay in those tags. Forcing this into some kind of spreadsheet tag wouldn't be accurate.

  • how to merge multiple url/path into multidimensional array ?

    - by KelNoReem
    I have array like this: $path = array ( [0] => site\projects\terrace_and_balcony\mexico.jpg [1] => site\projects\terrace_and_balcony\new_york.jpg [2] => site\projects\terrace_and_balcony\berlin.jpg [3] => site\projects\terrace_and_balcony\Kentucky.jpg [4] => site\projects\terrace_and_balcony\Utah.jpg [5] => site\projects\terrace_and_balcony\Hawaii.jpg [6] => site\projects\private_gardens\mexico.jpg [7] => site\projects\private_gardens\new_york.jpg [8] => site\projects\private_gardens\berlin.jpg [9] => site\projects\private_gardens\Kentucky.jpg [10] => site\projects\private_gardens\Utah.jpg [11] => site\projects\private_gardens\Hawaii.jpg ) How to convert it to that: $path11 = array ( "site"=>array ( "projects"=>array ( "terrace_and_balcony"=>array ( "mexico.jpg", "new_york.jpg", "berlin.jpg", "Kentucky.jpg", "Utah.jpg", "Hawaii.jpg" ), "private_gardens"=>array ( "mexico.jpg", "new_york.jpg", "berlin.jpg", "Kentucky.jpg", "Utah.jpg", "Hawaii.jpg" ) ) ) );

  • In C, is it possible do free only an array first ou last position?

    - by user354959
    Hi there! I've an array, but I don't need its first (or last) position. So I point a new variable to the rest of the array, but I should free the array first/last position. For instance: p = read_csv_file(); q = p + 1; // I don't need the first CSV file field // Here I'd like to free only the first position of p return q; Otherwise I've to memcpy the array to other variable, excluding the first position, and then free the original array. Like this: p = read_csv_file(); q = (int*) malloc(sizeof(int) * (SOME_SIZE - 1)); memcpy(q, p+1, sizeof(int) * (SOME_SIZE - 1)); free(p); return q; But then I'll have the overhead of copying all the array. Is this possible to only free a single position of an array?

  • Can I use array_push on a SESSION array in php?

    - by zeckdude
    I have an array that I want on multiple pages, so I made it a SESSION array. I want to add a series of names and then on another page, I want to be able to use a foreach loop to echo out all the names in that array. This is the session: $_SESSION['names'] I want to add a series of names to that array using array_push like this: array_push($_SESSION['names'],$name); I am getting this error: array_push() [function.array-push]: First argument should be an array Can I use array_push to put multiple values into that array? Or perhaps there is a better, more efficient way of doing what I am trying to achieve?

  • What is array portability?

    - by bobo
    From this page: http://www.doctrine-project.org/documentation/manual/1_2/en/working-with-models#dealing-with-relations:creating-related-records You can see that it says $obj['property']; is the recommended way of referring to an object's property in Doctrine for array portability purposes. I never heard about this term before and google did not come up with useful result. What is that?

  • Changing array values in a VBA dictionary

    - by Pawan Jain
    Hi I have a piece of code that does not seem to do what it is expected to do. VBA Arrays are mutable by all means, but it seems that when they are stored into a Dictionary as values of some keys, they are not mutable anymore. Any ideas? Sub foo() Dim mydict As New Dictionary mydict.Add "A", Array(1, 2, 3) MsgBox mydict("A")(1) ' The above shows 2, which is fine mydict("A")(1) = 34 MsgBox mydict("A")(1) ' The above also shows 2, which is not fine End Sub

    Hi all, I have an associative array in awk that gets populated like this... chr_count[$3]++ When I try to print my chr_counts I use this: for (i in chr_count) { print i,":",chr_count[i]; } But not surprisingly, the order of i is not sorted in any way.

  • Creating array with constant

    - by wrongusername
    I was working on a program in Netbeans on Linux using a gcc compiler when, upon switching to Visual C++ on Windows 7, the code failed to compile as Visual C++ says it expected constant expression on several lines. On Netbeans, I simply did something similar to char name[fullName.size()];, while on Visual C++, I tried, among other things, const int position = fullName.size(); char Name[position]; How can I create a constant to use for the array?

  • vb.net one dimensional string array manipulation difficulty

    - by Luay
    Hi, I am having some problems with manipulating a one dimensional string array in vb.net and would like your assistance please. My objective is to get 4 variables (if possible) from a file path. these variables are: myCountry, myCity, myStreet, Filename. All declared as string. The file location is also declared as string. so I have: Dim filePath As String to illustrate my problem and what I am trying to do I have the following examples: 1- C:\my\location\is\UK\Birmingham\Summer Road\this house.txt. In this example myCountry would be= UK. myCity= Birmingham. myStreet=Summer Road. Filename=this house.txt 2- C:\my Location\is\France\Lyon\that house.txt. here myCountry=France. myCity=Lyon. There is no street. Filename=that house.txt 3- C:\my Location is\Germany\the other house.txt Here myCountry=Germany. No city. No street. Filename=the other house.txt What I am trying to say is I have no idea before hand about the lenght of the string or the position of the variables I want. I also don't know if I am going to find/get a city or street name in the path. However I do now that i will get myCountry and it will be one of 5 options: UK, France, Germany, Spain, Italy. To tackle my problem, the first thing I did was Dim pathArr() As String = filePath.Split("\") to get the FileName I did: FileName = pathArr.Last To get myCountry I did: If filePath.Contains("UK") Then myCountry = "UK" ElseIf filePath.Contains("France") Then myCountry = "France" ElseIf filePath.Contains("Germany") Then myCountry = "Germany" ElseIf filePath.Contains("Spain") Then myCountry = "Spain" ElseIf filePath.Contains("Italy") Then myCountry = "Italy" End If in trying to figure out myCity and myStreet (and whether they exist in the string in the first place) I started with: Dim ind As Integer = Array.IndexOf(pathArr, myCountry) to get the index of the myCountry string. I thought I could make my way from there but I am stuck and don't know what to do next. Any help will be appreciated. Thanks

  • weird array syntax

    - by dnagirl
    I'm trying to figure how a function I've been given works -- or rather doesn't work. The problematic areas include array notation like this: $small[$end[$i]{0}] I think the idea is to append "0" to the value of $end[$i] and use that for the index of $small. But it doesn't work in PHP5.3. Is this a deprecated syntax and is it trying to do what I think it is?

I tried and all i got was the scrambling but there were always doubles :s
