• Excel 2003 - ADDRESS() function issues

  - by hairdresser-101

  I finally thought I had found a way to acutally use excel productively but the code that I followed does not appear to work. I'm thinking that the code is very limited and can't do what I want but I thought I'd ask to confirm - maybe it is my function that is the problem. I want to calculate the sum of a row of values for the previous month based on how many days we are into this month (i.e. It is the 20th of April so I want to sum the first 20 days of March to compare against.) =SUM(G4:ADDRESS(ROW(),7+$BR$3,4)) I basically want to SUM(G4:AA4) and have used the address function to return the cell reference AA4 by taking G4 and adding 20 to the column count. ADDRESS(ROW(),7+$BR$3,4) This successfully returns AA7 as expected HOWEVER, when I try to use the returning value in the SUM() function it throws an error... Am I not able to use this reference in my calculation?

• Compare range of ip addresses with start and end ip address in MySQL

  - by Maarten

  I have a MySQL table where I store IP ranges. It is setup in the way that I have the start address stored as a long, and the end address (and an id and some other data). Now I have users adding ranges by inputting a start and end ip address, and I would like to check if the new range is not already (partially) in the database. I know I can do a between query, but that doesn't seem to work with 2 different columns, and I also cannot figure out how to pass a range to compare it. Doing it in a loop in PHP is a possibility, but would with a range of e.g. 132.0.0.0-199.0.0.0 be quite a big amount of queries..

• Sort List C# in arbitrary order

  - by Jasper

  I have a C# List I.E. List<Food> x = new List<Food> () ; This list is populated with this class Public class Food { public string id { get; set; } public string idUser { get; set; } public string idType { get; set; } //idType could be Fruit , Meat , Vegetable , Candy public string location { get; set; } } Now i have this unsorted List<Food> list ; which has I.E. 15 elements. There are 8 Vegetable Types , 3 Fruit Types , 1 Meat Types , 1 Candy Types I would sort this so that to have a list ordered in this way : 1° : Food.idType Fruit 2° : Food.idType Vegetables 3° : Food.idType Meat 4° : Food.idType Candy 5° : Food.idType Fruit 6° : Food.idType Vegetables 7° : Food.idType Fruit //Becouse there isnt more Meat so i insert the //next one which is Candy but also this type is empty //so i start from begin : Fruit 8° : Food.idType Vegetables 9° : Food.idType Vegetables // For the same reason of 7° 10 ° Food.idType Vegetables ...... .... .... 15 : Food.idType Vegetables I cant find a rule to do this. Is there a linq or List.Sort instruction which help me to order the list in this way? Update i changed the return value of idType and now return int type instead string so 1=Vegetable , 2=Fruit , 3=Candy 4=Meat

• Linked list example using threads

  - by Carl_1789

  I have read the following code of using CRITICAL_SECTION when working with multiple threads to grow a linked list. what would be the main() part which uses two threads to add to linked list? #include <windows.h> typedef struct _Node { struct _Node *next; int data; } Node; typedef struct _List { Node *head; CRITICAL_SECTION critical_sec; } List; List *CreateList() { List *pList = (List*)malloc(sizeof(pList)); pList->head = NULL; InitializeCriticalSection(&pList->critical_sec); return pList; } void AddHead(List *pList, Node *node) { EnterCriticalSection(&pList->critical_sec); node->next = pList->head; pList->head = node; LeaveCriticalSection(&pList->critical_sec); } void Insert(List *pList, Node *afterNode, Node *newNode) { EnterCriticalSection(&pList->critical_sec); if (afterNode == NULL) { AddHead(pList, newNode); } else { newNode->next = afterNode->next; afterNode->next = newNode; } LeaveCriticalSection(&pList->critical_sec); } Node *Next(List *pList, Node *node) { Node* next; EnterCriticalSection(&pList->critical_sec); next = node->next; LeaveCriticalSection(&pList->critical_sec); return next; }

• Implementing list position locator in C++?

  - by jfrazier

  I am writing a basic Graph API in C++ (I know libraries already exist, but I am doing it for the practice/experience). The structure is basically that of an adjacency list representation. So there are Vertex objects and Edge objects, and the Graph class contains: list<Vertex *> vertexList list<Edge *> edgeList Each Edge object has two Vertex* members representing its endpoints, and each Vertex object has a list of Edge* members representing the edges incident to the Vertex. All this is quite standard, but here is my problem. I want to be able to implement deletion of Edges and Vertices in constant time, so for example each Vertex object should have a Locator member that points to the position of its Vertex* in the vertexList. The way I first implemented this was by saving a list::iterator, as follows: vertexList.push_back(v); v->locator = --vertexList.end(); Then if I need to delete this vertex later, then rather than searching the whole vertexList for its pointer, I can call: vertexList.erase(v->locator); This works fine at first, but it seems that if enough changes (deletions) are made to the list, the iterators will become out-of-date and I get all sorts of iterator errors at runtime. This seems strange for a linked list, because it doesn't seem like you should ever need to re-allocate the remaining members of the list after deletions, but maybe the STL does this to optimize by keeping memory somewhat contiguous? In any case, I would appreciate it if anyone has any insight as to why this happens. Is there a standard way in C++ to implement a locator that will keep track of an element's position in a list without becoming obsolete? Much thanks, Jeff

• how do I best create a set of list classes to match my business objects

  - by ken-forslund

  I'm a bit fuzzy on the best way to solve the problem of needing a list for each of my business objects that implements some overridden functions. Here's the setup: I have a baseObject that sets up database, and has its proper Dispose() method All my other business objects inherit from it, and if necessary, override Dispose() Some of these classes also contain arrays (lists) of other objects. So I create a class that holds a List of these. I'm aware I could just use the generic List, but that doesn't let me add extra features like Dispose() so it will loop through and clean up. So if I had objects called User, Project and Schedule, I would create UserList, ProjectList, ScheduleList. In the past, I have simply had these inherit from List< with the appropriate class named and then written the pile of common functions I wanted it to have, like Dispose(). this meant I would verify by hand, that each of these List classes had the same set of methods. Some of these classes had pretty simple versions of these methods that could have been inherited from a base list class. I could write an interface, to force me to ensure that each of my List classes has the same functions, but interfaces don't let me write common base functions that SOME of the lists might override. I had tried to write a baseObjectList that inherited from List, and then make my other Lists inherit from that, but there are issues with that (which is really why I came here). One of which was trying to use the Find() method with a predicate. I've simplified the problem down to just a discussion of Dispose() method on the list that loops through and disposes its contents, but in reality, I have several other common functions that I want all my lists to have. What's the best practice to solve this organizational matter?

• How to put data from List<string []> to dataGridView

  - by Kirill

  Try to put some data from List to dataGridView, but have some problem with it. Currently have method, that return me required List - please see picture below code public List<string[]> ReadFromFileBooks() { List<string> myIdCollection = new List<string>(); List<string[]> resultColl = new List<string[]>(); if (chooise == "all") { if (File.Exists(filePath)) { using (FileStream fs = new FileStream(filePath, FileMode.Open, FileAccess.Read)) { StreamReader sr = new StreamReader(fs); string[] line = sr.ReadToEnd().Split(new string[] { Environment.NewLine }, StringSplitOptions.RemoveEmptyEntries); foreach (string l in line) { string[] result = l.Split(','); foreach (string element in result) { myIdCollection.Add(element); } resultColl.Add(new string[] { myIdCollection[0], myIdCollection[1], myIdCollection[2], myIdCollection[3] }); myIdCollection.Clear(); } sr.Close(); return resultColl; } } .... this return to me required data in requred form (like list from arrays). After this, try to move it to the dataGridView, that already have 4 columns with names (because i'm sure, that no than 4 colums required) - please see pic below Try to put data in to dataGridView using next code private void radioButtonViewAll_CheckedChanged(object sender, EventArgs e) { TxtLibrary myList = new TxtLibrary(filePathBooks); myList.chooise = "all"; //myList.ReadFromFileBooks(); DataTable table = new DataTable(); foreach (var array in myList.ReadFromFileBooks()) { table.Rows.Add(array); } dataGridViewLibrary.DataSource = table; } But as result got error - "required more rows that exist in dataGridVIew", but accordint to what I'm see (pic above) q-ty of rows (4) equal q-ty of arrays element in List (4). Try to check result by putting additional temp variables - but it's ok - please see pic below Where I'm wrong? Maybe i use dataGridView not in correct way?

• Where to find a list of bad passwords?

  - by Steve Morgan

  I need to implement a 'stop list' to prevent users selecting common passwords in a new online service. Can anyone point me to such a list online anywhere? Edited: Note that I'm only trying to eliminate the most common passwords, not an exhaustive dictionary. And, of course, this complements a reasonably strong password policy (length, use of non-alpha characters, etc.) Thanks.

• Global menu not showing in Ubuntu 12.10 with Unity

  - by William

  I am on Ubuntu 12.10 with Unity shell. I am not quite sure what happened, but today I noticed that the menubar (containing 'File, Edit, etc...') is not appearing on the panel as it used to (i.e. the global application menu), but on the application window under the title bar. The only application that still uses global menu is Chromium. Any ideas what settings may have changed? Also, when I right click on the desktop and select "Change Desktop Background", System Settings opens, instead of the "Appearance" settings. Apparently, here is a related question, with no answer: Global menu and HUD suddenly broken EDIT: I noticed this behavior on three of my computers after an update (I do not remember exactly which packages were updated). Now when I try to run apt-get upgrade, I get: The following packages have been kept back: gnome-control-center gnome-control-center-data I guess something is going on with updates. Any info would be appreciated.

• jquery Ajax sortable list stops being sortable when Ajax call updates the list html

  Hi, I am using jquery 1.4.2 and trying to achieve the following: 1 - function call that sends a value to a php page to add/remove an item 2 - returns html list of the items 3 - list should still be sortable 4 - save (serialise list) onclick My full WIP is located here [http://www.chittak.co.uk/test4/index_nw3.php][1] I tried to delegate from the level above the UL but I could get this to work $("#construnctionstage").delegate('ul li', 'click', function(){ The initial list is sortable, when you click add/remove the ajax function returns a new list with the a number of items, BUT I am doing something wrong as the alert message continues to work while the list is no longer sortable. $(document).ready(function(){ $('ul').delegate('li', 'click', function(){ alert('You clicked on an li element!'); /*$("#test-list").sortable({ handle : '.handle', update : function () { var order = $('#test-list').sortable('serialize'); $("#info").load("process-sortable.php?"+order); } });*/ }).sortable({ handle : '.handle', update : function () { var order = $('#test-list').sortable('serialize'); $("#info").load("process-sortable.php?"+order); } }); }); <div id="construnctionstage"> <ul id="test-list"> <li id="listItem_1">

• Passing a non-iterable to list.extend ()

  - by JS

  Hello, I am creating a public method to allow callers to write values to a device, call it write_vals() for example. Since these values will by typed live, I would like to simplify the user's life by allowing them type in either a list or a single value, depending on how many values they need to write. For example: write_to_device([1,2,3]) or write_to_device(1) My function would like to work with a flat list, so I tried to be clever and code something like this: input_list = [] input_list.extend( input_val ) This works swimmingly when the user inputs a list, but fails miserably when the user inputs a single integer: TypeError: 'int' object is not iterable Using list.append() would create a nested list when a list was passed in, which would be an additional hassle to flatten. Checking the type of the object passed in seems clumsy and non-pythonic and wishing that list.extend() would accept non-iterables has gotten me nowhere. So has trying a variety of other coding methods. Suggestions (coding-related only, please) would be greatly appreciated.

• Converting non-generic List type to Generic List type in Java 1.5

  - by Shaun F

  I have a List that is guaranteed to contain just one type object. This is created by some underlying code in a library that I cannot update. I want to create a List<ObjectType> based on the incoming List object so that my calling code is talking to List<ObjectType>. What's the best way to convert the List (or any other object collection) to a List<ObjectType>.

• How to combine elements of a list

  - by Addie

  I'm working in c#. I have a sorted List of structures. The structure has a DateTime object which stores month and year and an integer which stores a value. The list is sorted by date. I need to traverse the list and combine it so that I only have one instance of the structure per date. For example: My initial list would look like this: { (Apr10, 3), (Apr10, 2), (Apr10, -3), (May10, 1), (May10, 1), (May10, -3), (Jun10, 3) } The resulting list should look like this: { (Apr10, 2), (May10, -1), (Jun10, 3) } I'm looking for a simple / efficient solution. The struct is: class CurrentTrade { public DateTime date; public int dwBuy; } The list is: private List<CurrentTrade> FillList

• Iterator for second to last element in a list

  - by BSchlinker

  I currently have the following for loop: for(list<string>::iterator jt=it->begin(); jt!=it->end()-1; jt++) I have a list of strings which is in a larger list (list<list<string> >). I want to loop through the contents of the innerlist until I get to the 2nd to last element. This is because I have already processed the contents of the final element, and have no reason to process them again. However, using it->end()-1 is invalid -- I cannot use the - operator here. While I could use the -- operator, this would decrement this final iterator on each cycle. I believe a STL list is a doubly linked list, so from my perspective, it should be possible to do this. Advice? Thanks in advance

• Query a List of List of Items in LINQ c#

  - by call me Steve

  I am a bit new to LINQ, here is my problem. I have a List of List of Items I like to get the Items which are present in only one List (and if I could get the List in which they are without re-iterating through the "list of list" that would be great). I am trying without success to use the Aggregate / Except / Group keywords in the Linq query but nothing close to a solution so far.

• Ensuring the contacts in a Distribution List are displayed with both name and email address

  - by hawbsl

  How can I ensure the contacts I add to an Outlook distribution list are displayed with both name and email address? These contacts may not exist in any other address book, just the distribution list. Currently they show up just as an email address (in both columns). Here's roughly the VBA we're using: Do Until RS.EOF //here's where we want to inject RS!FirstName, RS!Surname etc objRecipients.Add RS!Email objRecipients.Resolve RS.MoveNext Loop Set objDistList = contactsFolder.Items.Add("IPM.DistList") objDistList.DLName = "Whatever" objDistList.AddMembers objRecipients objDistList.Save etc

• Merge object from list by comparing one value

  - by Bala

  I have two List of Objects (one is master list and other is error list) and if there is a match of one value when compared two lists then merge all other error list values into mast list value (only one object). Other than iterating is there any other way to compare a value and then merge that object. Object is a Value object with some setters and getters. Appreciate your help. List<OrderVO> masterList; List<OrderVO> errorList; If errorList.OrderVO.getOrderID = masterList.OrderVO.getOrderID then masterList.OrderVO.merge(errorList.OrderVO) or copy all values of masterList.OrderVO.copy(errorList.OrderVO). Hoper this is clear

• Dividing a list in specific number of sublists

  - by Surya

  I want to divide a list in "a specific number of" sublists. That is, for example if I have a list List(34, 11, 23, 1, 9, 83, 5) and the number of sublists expected is 3 then I want List(List(34, 11), List(23, 1), List(9, 83, 5)). How do I go about doing this? I tried grouped but it doesn't seem to be doing what I want. PS: This is not a homework question. Kindly give a direct solution instead of some vague suggestions.

• Printing a list using reflection

  public class Service{ String serviceName; //setter and getter } public class Version{ String VersionID; //setter and getter } public void test(Object list){ //it shd print the obtained list } List< Service list1; //Service is a Bean List< Version list2; //Version is a Bean test(list1); test(list2); Now the test method shd print the obtained list - (i.e) If the list is of type Service ,then serviceName should be printed using its getter. If the list type is Version versionID should be printed. Is it possible to achieve this without using Interface or abstract class?

• Body of email breaks distribution list in exchange?

  - by widgisoft

  Hi, I have a very odd problem that I'm not sure is a programming issue or a server issue :-p. Basically I'm sending an email to an exchange distribution list that includes a PHP stack trace; during certain faults the trace includes really high level information such as the machine's environment variables (during file reads, etc.). I went through a copy of the email line by line until the email sent and it appears the line: [SUDO_COMMAND] => /etc/init.d/httpd restart is the culprit. Adding a string replacement in before the email is sent allows a successful send. What I don't understand is WHY these stream of characters are causing the issue ONLY on the distribution email. If I send the email to myself as well, i.e. "[email protected]; [email protected]", then I get the email fine. Re-ordering the list doesn't make a difference the group never gets the email. Because the individual gets the email and not the group I'm assuming the fault is with exchange and some rogue filtering - I've gone through it with the sysadmins and there's no filtering of any sort on that group... so maybe it's a bug? I can't find anyone else having recorded this specific fault so I figured I'd open it here. For now I'm just not using the distribution list but it'd be nice to eventually find the solution. Many thanks, Chris
