• Cisco 800 series won't forward port

  - by sam

  Hello ServerFault, I am trying to forward port 444 from my cisco router to my Web Server (192.168.0.2).

• List of dict in Python

  - by plalex

  Hi everybody, I've got a list of dict in Python: dico_cfg = {'name': entry_name, 'ip': entry_ip, 'vendor': combo_vendor, 'stream': combo_stream} self.list_cfg.append(dico_cfg) I append to my list a lot of dict in the same way. Now I would like to delete one dict and only one dict in this list? What is the best way to proceed? I've try with the index of the list, but when I remove a dict from the list, the index is modify, so after some random remove my index doesn't correspond anymore to the dict I want to remove in my list. I hope that is clear. Maybe I can add an "id" row in my dict, so I can ask to remove more preciously the dict I want. I'll ask to remove the dict where id is equal to the id's dict I want to remove. How can I do that? I hope I'm enough clear. Sorry but I'm a newbie in Python.

• Set selection in Dashcode List Controller

  - by wpearse

  I have a list controller in my Dashcode project, it pulls its data from a dynamic source. After my list controller has loaded its data I'd like to set it's selected index to 0 - so that information for the first item in the list is shown. I can't for the life of me figure out how to do this. I've tried: function load() { dashcode.setupParts(); var list = document.getElementById("itemsList"); //list.setSelectionIndexes(0); // nope //list.selectedIndex = 0; // nope }

• Using the sharepoint stsadm import command fails when list exists

  - by 78lro

  When using the stsadm -o import command in sharepoint I am getting an error relating to a list already existing, the import then seems to fail. Should it not handle this scenario of a list already existing on the destination server? I then used the UI to delete the existing list and ran the import again. It then seemed to fail at the same point saying the list exists. In the UI the list appears but when I click it, it reports that the list does not exist - almost as if it's stuck in a half created state, unable to be deleted or created by the import. Any suggestions greatly appreciated.

• java casting a list

  - by dcp

  Let's say I had: protected void performLogic(List<Object> docs) { ... } In the code where I'm going to be calling this method, I have a List<String> list. I want to call performLogic, passing this list. But it won't work because the lists are 2 different types: public void execute() { List<String> docs = new ArrayList<String>(); performLogin(docs); // won't work } I tried casting to List<Object> also, but that won't work either. So is the only way to do this is to make a new ArrayList of Object and just add the values and then pass it? Just seems cumbersome. I wondered if there was a better way to do it. Thanks.

• Search algorithm for a sorted double linked list

  - by SalamiArmi

  As a learning excercise, I've just had an attempt at implementing my own 'merge sort' algorithm. I did this on an std::list, which apparently already had the functions sort() and merge() built in. However, I'm planning on moving this over to a linked list of my own making, so the implementation is not particuarly important. The problem lies with the fact that a std::list doesnt have facilities for accessing random nodes, only accessing the front/back and stepping through. I was originally planning on somehow performing a simple binary search through this list, and finding my answer in a few steps. The fact that there are already built in functions in an std::list for performing these kinds of ordering leads me to believe that there is an equally easy way to access the list in the way I want. Anyway, thanks for your help in advance!

• Copy a linked list

  - by emkrish

  typedef struct Node { int data; Node *next; Node *other; }; Node *pHead; pHead is a singly linked list. The next field points to the next element in the list. The other field may point to any other element (could be one of the previous nodes or one of the nodes ahead) in the list or NULL. How does one write a copy function that duplicates the linked list and its connectivity? None of the elements (next and other) in the new list should point to any element in the old list.

• Create a mirrored linked list in Java

  - by glacier89

  Linked-List: Mirror Consider the following private class for a node of a singly-linked list of integers: private class Node{ public int value; public Node next; } A wrapper-class, called, ListImpl, contains a pointer, called start to the first node of a linked list of Node. Write an instance-method for ListImpl with the signature: public void mirror(); That makes a reversed copy of the linked-list pointed to by start and appends that copy to the end of the list. So, for example the list: start 1 2 3 after a call to mirror, becomes: start 1 2 3 3 2 1 Note: in your answer you do not need to dene the rest of the class for ListImpl just the mirror method.

• Traverse list to add elements, C#.

  - by Addie

  I have a list of objects. Each object has an integer quantity and a DateTime variable which contains a month and year value. I'd like to traverse the list and pad the list by adding missing months (with quantity 0) so that all consecutive months are represented in the list. What would be the best way to accomplish this? Example: Original List { Jan10, 3 }, { Feb10, 4 }, { Apr10, 2 }, { May10, 2 }, { Aug10, 3 }, { Sep10, -3 }, { Oct10, 6 }, { Nov10, 3 }, { Dec10, 7 }, { Feb11, 3 } New List { Jan10, 3 }, { Feb10, 4 }, {Mar10, 0}, { Apr10, 2 }, { May10, 2 }, { Jun10, 0 }, { Jul10, 0 } { Aug10, 3 }, { Sep10, -3 }, { Oct10, 6 }, { Nov10, 3 }, { Dec10, 7 }, { Jan11, 0 }, { Feb11, 3 }

• defining < operator for map of list iterators

  - by Adrian

  I'd like to use iterators from an STL list as keys in a map. For example: using namespace std; list<int> l; map<list<int>::const_iterator, int> t; int main(int argv, char * argc) { l.push_back(1); t[l.begin()] = 5; } However, list iterators do not have a comparison operator defined (in contrast to random access iterators), so compiling the above code results in an error: /usr/include/c++/4.2.1/bits/stl_function.h:227: error: no match for ‘operator<’ in ‘__x < __y’ If the list is changed to a vector, a map of vector const_iterators compiles fine. What is the appropriate way to define the operator < for list::const_iterator?

• Extract item in a list if Contains returns true

  - by Matt

  I have two lists A and B, at the beginning of my program, they are both filled with information from a database (List A = List B). My program runs, List A is used and modified, List B is left alone. After a while I reload List B with new information from the database, and then do a check with that against List A. foreach (CPlayer player in ListA) if (ListB.Contains(player)) ----- Firstly, the object player is created from a class, its main identifier is player.Name. If the Name is the same, but the other variables are different, would the .Contains still return true? Class CPlayer( public CPlayer (string name) _Name = name At the ---- I need to use the item from ListB that causes the .Contains to return true, how do I do that?

• Fill a list from JSP in Spring

  - by Javi

  Hello, I have something like this in my Spring Application: public class Book{ public Book(){ sheets = new LinkedList<Sheet>(); } protected List<Sheet> sheets; //getter and setter } I add several Sheets to the sheet list and I print a form in a JSP like this: <form:form modelAttribute="book" action="${dest_url}" method="POST"> <c:forEach items="${mybook.sheets}" var="sheet" varStatus="status"> <form:hidden path="sheet[${status.count -1}].header"/> <form:hidden path="sheet[${status.count -1}].footer"/> <form:hidden path="sheet[${status.count -1}].operador"/> <form:hidden path="sheet[${status.count -1}].number"/> <form:hidden path="sheet[${status.count -1}].lines"/> </c:forEach> ... </form:form> I need to get back this list in the controller when the form is submitted. So in my controller I have a method with a parameter like this: public String myMethod (@ModelAttribute("book") Book book, Model model){ ... } The problem is that it doesn't fill the sheets list unless in the constructor of Book I add as much Sheet's as I want to get. The problem is that I don't know in advance the number of Sheets the book is going to have. I think the problem is that in my method it instantiates Book which has a list of sheets with 0 elements. When it tries to access to sheets[0] the list is empty and it doen't add a Sheet. I've tried to create a getter method for the list with an index parameter (so it can create the element if it doesn't exists in the list like in Struts framework) like this one: public Sheet getSheets(int index){ if(sheets.size() <= index){ Sheet sheet = new Sheet(); sheets.add(index, sheet); } Sheet sheetToReturn = sheets.get(index); if(sheetToReturn == null){ sheetToReturn = new Sheet(); sheets.add(index, sheetToReturn); } return sheetToReturn; } but with this method the JSP doesn't work because sheets has an invalid getter. What's the proper way of filling a list when you don't know the number of items in advanced? Thanks

• C#: Put member variables into a list.

  - by David

  Hi all Assuming I have a method which accepts an IList or similar thing as a parameter: public void JiggleMyList(IList<string> list)... Is there an easy way that I can pass in string members of a list of objects? I mean, if for example, I have a list of Person objects which expose a string property called FullName, is there a quick way to stuff the FullNames of all the Person objects into the method parameter, or do I have to create a new List and iterate through the Person objects: List<string> fullNames = new List<string>; foreach (Person person in people) { fullNames.Add(person.FullName); } JiggleMyList(fullNames); I come across this all the time, and it would be nice if there was a shortcut. Many thanks David

• Wondering about a way to conserve memory in C# using List<> with structs

  - by Michael Ryan

  I'm not even sure how I should phrase this question. I'm passing some CustomStruct objects as parameters to a class method, and storing them in a List. What I'm wondering is if it's possible and more efficient to add multiple references to a particular instance of a CustomStruct if a equivalent instance it found. This is a dummy/example struct: public struct CustomStruct { readonly int _x; readonly int _y; readonly int _w; readonly int _h; readonly Enum _e; } Using the below method, you can pass one, two, or three CustomStruct objects as parameters. In the final method (that takes three parameters), it may be the case that the 3rd and possibly the 2nd will have the same value as the first. List<CustomStruct> _list; public void AddBackground(CustomStruct normal) { AddBackground(normal, normal, normal); } public void AddBackground(CustomStruct normal, CustomStruct hover) { AddBackground(normal, hover, hover); } public void AddBackground(CustomStruct normal, CustomStruct hover, CustomStruct active) { _list = new List<CustomStruct>(3); _list.Add(normal); _list.Add(hover); _list.Add(active); } As the method stands now, I believe it will create new instances of CustomStruct objects, and then adds a reference of each to the List. It is my understanding that if I instead check for equality between normal and hover and (if equal) insert normal again in place of hover, when the method completes, hover will lose all references and eventually be garbage collected, whereas normal will have two references in the List. The same could be done for active. That would be better, right? The CustomStruct is a ValueType, and therefore one instance would remain on the Stack, and the three List references would just point to it. The overall List size is determined not by the object Type is contains, but by its Capacity. By eliminating the "duplicate" CustomStuct objects, you allow them to be cleaned up. When the CustomStruct objects are passed to these methods, new instances are created each time. When the structs are added to the List, is another copy made? For example, if i pass just one CustomStruct, AddBackground(normal) creates a copy of the original variable, and then passes it three times to Addbackground(normal, hover, active). In this method, three copies are made of the original copy. When the three local variables are added to the List using Add(), are additional copies created inside Add(), and does that defeat the purpose of any equality checks as previously mentioned? Am I missing anything here?

I am using the following code: GridView1.DataSource = myList.GetQ(); GrdiView1.DataBind(); myList.GetQ() returns a List which is an array of "Question". When I set the column DataField to "!" I get the object Question. My question is how can I get the objects property? I tried "!.Ordinal" does not work. I was reading this post for reference, here, any help is greatly appreciated, thanks.

• linked list elements gone?

  - by Hristo

  I create a linked list dynamically and initialize the first node in main(), and I add to the list every time I spawn a worker process. Before the worker process exits, I print the list. Also, I print the list inside my sigchld signal handler. in main(): head = NULL; tail = NULL; // linked list to keep track of worker process dll_node_t *node; node = (dll_node_t *) malloc(sizeof(dll_node_t)); // initialize list, allocate memory append_node(node); node->pid = mainPID; // the first node is the MAIN process node->type = MAIN; in a fork()'d process: // add to list dll_node_t *node; node = (dll_node_t *) malloc(sizeof(dll_node_t)); append_node(node); node->pid = mmapFileWorkerStats->childPID; node->workerFileName = mmapFileWorkerStats->workerFileName; node->type = WORK; functions: void append_node(dll_node_t *nodeToAppend) { /* * append param node to end of list */ // if the list is empty if (head == NULL) { // create the first/head node head = nodeToAppend; nodeToAppend->prev = NULL; } else { tail->next = nodeToAppend; nodeToAppend->prev = tail; } // fix the tail to point to the new node tail = nodeToAppend; nodeToAppend->next = NULL; } finally... the signal handler: void chld_signalHandler() { dll_node_t *temp1 = head; while (temp1 != NULL) { printf("2. node's pid: %d\n", temp1->pid); temp1 = temp1->next; } int termChildPID = waitpid(-1, NULL, WNOHANG); dll_node_t *temp = head; while (temp != NULL) { if (temp->pid == termChildPID) { printf("found process: %d\n", temp->pid); } temp = temp->next; } return; } Is it true that upon the worker process exiting, the SIGCHLD signal handler is triggered? If so, that would mean that after I print the tree before exiting, the next thing I do is in the signal handler which is print the tree... which would mean i would print the tree twice? But the tree isn't the same. The node I add in the worker process doesn't exist when I print in the signal handler or at the very end of main(). Any idea why? Thanks, Hristo

• Python: Elegant way to check if at least one regex in list matches a string

  - by houbysoft

  Hi. I have a list of regexes in python, and a string. Is there an elegant way to check if the at least one regex in the list matches the string? By elegant, I mean something better than simply looping through all of the regexes and checking them against the string and stopping if a match is found. Basically, I had this code: list = ['something','another','thing','hello'] string = 'hi' if string in list: pass # do something else: pass # do something else Now I would like to have some regular expressions in the list, rather than just strings, and I am wondering if there is an elegant solution to check for a match to replace if string in list:. Thanks in advance.

• Most efficient way for a lookup/search in a huge list (python)

  - by user229269

  Hey guys, -- I just parsed a big file and I created a list containing 42.000 strings/words. I want to query [against this list] to check if a given word/string belongs to it. So my question is: What is the most efficient way for such a lookup? A first approach is to sort the list [list.sort()] and then just use the if word in list: print 'word' -- which is really trivial and I am sure there is a better way to do it. My goal is to apply a fast lookup that finds whether a given string is in this list or not. If you have any ideas of another data structure, they are welcome. Yet, I want to avoid for now more sophisticated data-structures like Tries etc. I am interested in hearing ideas (or tricks) about fast lookups or any other python library methods that might do the search faster than the simple 'in'. Thanks in advance!

• Custom cell in list in Flash AS3

  - by Stian Flatby

  I am no expert in Flash, and I need some quick help here, without needing to learn everything from scratch. Short story, I have to make a list where each cell contains an image, two labels, and a button. List/Cell example: img - label - label - button img - label - label - button As a Java-programmer, I have tried to quicly learn the syntax and visualness of Flash and AS3, but with no luck so far. I have fairly understood the basics of movie clips etc. I saw a tutorial on how to add a list, and add some text to it. So I dragged in a list, and in the code went list.addItem({label:"hello"}); , and that worked ofc. So i thought if I double-clicked the MC of the list, i would get to tweak some things. In there I have been wandering around different halls of cell-renderers etc. I have now come to the point that I entered the CellRenderer_skinUp or something, and customized it to my liking. When this was done, I expected i could use list.addItem(); and get an empty "version" of my cell, with the img, labels and the button. But AS3 expects an input in addItem. From my object-oriented view, I am thinking that i have to create an object of the cell i have made, but i have no luck reaching it.. I tried to go var test:CellRenderer = list.listItem; list.addItem(test); ..But with no luck. This is just for funsies, but I really want to make this work, however not so much that I am willing to read up on ALOT of Flash and AS3. I felt that I was closing in on the prize, but the compiler expected a semicolon after the variable (list.addItem({test:something});). Note: If possible, I do NOT want this: list.addItem({image:"src",label:"text",label"text",button:"text"}); Well.. It actually is what I want, but I would really like to custom-draw everything. Does anyone get what I am trying to do, and has any answers for me? Am I approaching this the wrong way? I have searched the interwebs for custom list-cells, but with no luck. Please, any guiding here is appreciated! Sti

• Java List Sorting: Is there a way to keep a list permantly sorted automatically like TreeMap?

  - by david

  In Java you can build up an ArrayList with items and then call: Collections.sort(list, comparator); Is there anyway to pass in the Comparator at the time of List creation like you can do with TreeMap? The goal is to be able add an element to the list and instead of having it automatically appended to the end of the list, the list would keep itself sorted based on the Comparator and insert the new element at the index determined by the Comparator. So basically the list might have to re-sort upon every new element added. Is there anyway to achieve this in this way with the Comparator or by some other similar means? Thanks.

• Prolog: find all numbers of unique digits that can be formed from a list of digits

  - by animo

  The best thing I could come up with so far is this function: numberFromList([X], X) :- digit(X), !. numberFromList(List, N) :- member(X, List), delete(List, X, LX), numberFromList(LX, NX), N is NX * 10 + X. where digit/1 is a function verifying if an atom is a decimal digit. The numberFromList(List, N) finds all the numbers that can be formed with all digits from List. E.g. [2, 3] -> 23, 32. but I want to get this result: [2, 3] -> 2, 3, 23, 32 I spent a lot of hours thinking about this and I suspect you might use something like append(L, _, List) at some point to get lists of lesser length. I would appreciate any contribution.
