• Limit number of concurrent user logins in Windows Server 2008 Active Directory

  - by smhnaji

  Is there the possibility to limit Active Directory users' max concurrent login sessions? I've read many articles and discussions about the solution, but none of them seem to be working. Many had suggested UserLogin script that doesn't work in Windows Server 2008. Some other suggested CConnect that is not good enough. It's also very complicated. Some others have introduced UserLock that should be paid for. It's wondering that Windows Server 2003 DOES have the feature (wile as a third-party), but Windows Server 2008 doesn't have! One of the articles I've read: http://www.edugeek.net/forums/windows-server-2008-r2/61216-multiple-logins.html

• Change AccountName/LoginName for a SharePoint User (SPUser)

  - by Rohit Gupta

  Consider the following: We have an account named MYDOMAIN\eholz. This accounts Active Directory Login Name changes to MYDOMAIN\eburrell Now this user was a active user in a Sharepoint 2010 team Site, and had a userProfile using the Account name MYDOMAIN\eholz. Since the AD LoginName changed to eburrell hence we need to update the Sharepoint User (SPUser object) as well update the userprofile to reflect the new account name. To update the Sharepoint User LoginName we can run the following stsadm command on the Server: STSADM –o migrateuser –oldlogin MYDOMAIN\eholz –newlogin MYDOMAIN\eburrell –ignoresidhistory However to update the Sharepoint 2010 UserProfile, i first tried running a Incremental/Full Synchronization using the User Profile Synchronization service… this did not work. To enable me to update the AccountName field (which is a read only field) of the UserProfile, I had to first delete the User Profile for MYDOMAIN\eholz and then run a FULL Synchronization using the User Profile Synchronization service which synchronizes the Sharepoint User Profiles with the AD profiles. Update: if you just run the STSADM –o migrateuser command… the profile also gets updated automatically. so all you need is to run the stsadm –o migrate user command and you dont need to delete and recreate the User Profile

• Best Way to Handle Meta Information in a SQL Database

  - by danielhanly.com

  I've got a database where I want to store user information and user_meta information. The reason behind setting it up in this way was because the user_meta side may change over time and I would like to do this without disrupting the master user table. If possible, I would like some advice on how to best set up this meta data table. I can either set it as below: +----+---------+----------+--------------------+ | id | user_id | key | value | +----+---------+----------+--------------------+ | 1 | 1 | email | [email protected] | | 2 | 1 | name | user name | | 3 | 1 | address | test address | ... Or, I can set it as below: +----+---------+--------------------+--------------------+--------------+ | id | user_id | email | name | address | +----+---------+--------------------+--------------------+--------------+ | 1 | 1 | [email protected] | user name | test address | Obviously, the top verison is more flexible, but the bottom version is space saving and perhaps more efficient, returning all the data as a single record. Which is the best way to go about this? Or, am I going about this completely wrong and there's another way I've not thought of?

• Java List with Objects - find and replace (delete) entry if Object with certain attribute already ex

  - by Sophomore

  Hi there I've been working all day and I somehow can't get this probably easy task figured out - probably a lack of coffee... I have a synchronizedList where some Objects are being stored. Those objects have a field which is something like an ID. These objects carry information about a user and his current state (simplified). The point is, that I only want one object for each user. So when the state of this user changes, I'd like to remove the "old" entry and store a new one in the List. protected static class Objects{ ... long time; Object ID; ... } ... if (Objects.contains(ID)) { Objects.remove(ID); Objects.add(newObject); } else { Objects.add(newObject); } Obviously this is not the way to go but should illustrate what I'm looking for... Maybe the data structure is not the best for this purpose but any help is welcome!

• How to select a rectangle from List<Rectangle[]> with Linq

  - by dboarman

  I have a list of DrawObject[]. Each DrawObject has a Rectangle property. Here is my event: List<Canvas.DrawObject[]> matrix; void Control_MouseMove ( object sender, MouseEventArgs e ) { IEnumerable<Canvas.DrawObject> tile = Enumerable.Range( 0, matrix.Capacity - 1) .Where(row => Enumerable.Range(0, matrix[row].Length -1) .Where(column => this[column, row].Rectangle.Contains(e.Location))) .????; } I am not sure exactly what my final select command should be in place of the "????". Also, I was getting an error: cannot convert IEnumerable to bool. I've read several questions about performing a linq query on a list of arrays, but I can't quite get what is going wrong with this. Any help? Edit Apologies for not being clear in my intentions with the implementation. I intend to select the DrawObject that currently contains the mouse location.

• Finding the index of a list item in jQuery

  - by Tim Piele

  I have an unordered list of eight items. On page load the first five <li> have default thumbnail images in them and the 6th one has a 1px by 1px placeholder image with the ID of $('#last'). When a user inserts a new image it replaces the 'src' of $('#last') with their new image. It's not the most efficient way but it works. <ul> <li><img src="img1.png" /></li> <li><img src="img2.png" /></li> <li><img src="img3.png" /></li> <li><img src="img4.png" /></li> <li><img src="img5.png" /></li> <li><img src="1px.png" id="last"/></li> <li></li> <li></li> </ul> When the user adds a new image the ID of $('#last') is removed and I use each() to find the next empty <li> and insert the 1px by 1px image in it, with an ID of $('#last') so it is ready for the next image upload. At this point I need to get the index() of the <li> that now has the 1px by 1px image in it, whose ID is $('#last'), so that I can store the index in the session, so when a user comes back to the page the $('#last') ID is still set and ready to accept another image. How do I get the index of the <li> with that image in it, since it was set after page load? Is there a way to use delegate() or on() to get it? i.e. how do I get the index of an element that was set after page load?

• How to Object Array to List

  - by Peter Black

  (C#) I have 2 classes. 1 is called Employee. The other is my "main". I am trying to take a list and assign each value in list to an array of Employee object. //Inside "Main" class int counter = NameList.Count; Employee[] employee = new Employee[counter]; for (int i = 0; i <= counter; i++) { employee[i].Name = NameList[i]; employee[i].EmpNumber = EmpNumList[i]; employee[i].DateOfHire = DOHList[i]; employee[i].Salary = SalaryList[i]; employee[i].JobDescription = JobDescList[i]; employee[i].Department = DeptList[i]; } This returns the error: An unhandled exception of type 'System.NullReferenceException' occurred in Pgm4.exe Additional information: Object reference not set to an instance of an object. I think this means that I am not calling the list properly. Any help would be much appreciated. Thank you.

• How to access the element of a list/vector that passed by reference in C++

  - by bsoundra

  Hi all, The problem is passing lists/vectors by reference int main(){ list<int> arr; //Adding few ints here to arr func1(&arr); return 0; } void func1(list<int> * arr){ // How Can I print the values here ? //I tried all the below , but it is erroring out. cout<<arr[0]; // error cout<<*arr[0];// error cout<<(*arr)[0];//error //How do I modify the value at the index 0 ? func2(arr);// Since it is already a pointer, I am passing just the address } void func2(list<int> *arr){ //How do I print and modify the values here ? I believe it should be the same as above but // just in case. } Is the vectors any different from the lists ? Thanks in advance. Any links where these things are explained elaborately will be of great help. Thanks again.

• python matrices - list index out of range

  - by user1888493

  I am writing a function, that takes a matrix as input, such as the one below. Then the it returns the matrix' inverse, where all the 1s are changed to 0s and all the 0s changed to 1s, while keeping the diagonal from top left to bottom right 0s. An example input: g1 = [[0, 1, 1, 0], [1, 0, 0, 1], [1, 0, 0, 1], [0, 1, 1, 0]] the function should output this: g1 = [[0, 0, 0, 1], [0, 0, 1, 0], [0, 1, 0, 0], [1, 0, 0, 0]] When I run the program, it raises a list index out of range error. I'm sure this happens, because the loops I have set up are trying to access values that do not exist. But how do I allow an input of unknown row and column size? I only know how to do this with a single list, but a list of lists? Following you see the transforming function, but not the test function that calls it: def inverse_graph(graph): # take in graph # change all zeros to ones and ones to zeros r, c = 0, 0 # row, column equal zero while (graph[r][c] == 0 or graph[r][c] == 1): # while the current row has a value. while (graph[r][c] == 0 or graph[r][c] == 1): # while the current column has a value if (graph[r][c] == 0): graph[r][c] = 1 elif (graph[r][c] == 1): graph[r][c] = 0 c+=1 c=0 r+=1 c=0 r=0 # sets diagonal to zeros while (g1[r][c] == 0 or g1[r][c] == 1): g1[r][c]=0 c+=1 r+=1 return graph

• Meaning of NEXT in Linked List creation in perl

  - by seleniumnewbie

  So I am trying to learn Linked Lists using Perl. I am reading "Mastering Algorithms with Perl" by Job Orwant. In the book he explains how to create a linked list I understand most of it, but I just simply fail to understand the command/index/key NEXT in the second last line of the code snippet. $list=undef; $tail=\$list; foreach (1..5){ my $node = [undef, $_ * $_]; $$tail = $node; $tail = \${$node->[NEXT]}; # The NEXT on this line? } What is he trying to do there? Isn $node a scalar, which stores the address of the unnamed array. Also even if we are de-referencing $node, should we not refer to the individual elements by an index number example (0,1). If we do use "NEXT" as a key, is $node a reference to a hash? I am very confused. Something in plain English will be highly appreciated.

• looping array inside list in c#

  - by 3yoon af

  I have a list of array that contains multiple arrays. each array has 2 index .. First, I want to loop the list. Then i want to loop the array inside the list .. How can i do that ? I try to use this way, but it doesn't work ! foreach (string[] s in ArrangList1) { int freq1 = int.Parse(s[1]); foreach (string[] s1 in ArrangList) { int freq2 = int.Parse(s1[1]); if (freq1 < freq2) { backup = s; index1 = ArrangList1.IndexOf(s); index2 = ArrangList.IndexOf(s1); ArrangList[index1] = s1; ArrangList[index2] = s; } backup = null; } } it give me error in line 4.. I try to do the loop using other way .. but i don't know how to continue ! for (int i = 0; i < ArrangList1.Count; i++) { for (int j = 0; j < ArrangList1[i].Length; j++) { ArrangList1[i][1]; } } I use C# language .. Can someone help me, please?

• Python & Pygame: Updating all elements in a list under a loop during iteration

  - by Unit978

  i am working on a program in Python and using Pygame. this is what the basic code looks like: while 1: screen.blit(background, (0,0)) for event in pygame.event.get(): if event.type == QUIT: pygame.quit() sys.exit() if event.type == KEYDOWN and event.key == K_c: circle_create = True circle_list.append(Circle()) if event.type == MOUSEBUTTONDOWN and circle_create == True: if clicks == 0: circle_list[i].center() clicks += 1 if event.type == MOUSEMOTION and clicks == 1 and circle_create == True: circle_list[i].stretch() these if statements are under the while loop not the for loop since they dont require input from the user if circle_create == True: circle_list[i].draw_circle() if clicks == 2: clicks = 0 i += 1 circle_create = False pygame.display.update() what i want to do is have the object's function of draw_circle() to be constantly updated by the loop so that the drawn circle is shown for all objects in the list, but since the list is iterated it updates the new object added and the objects already appended are not updated. The program, works, it draws the circles upon user input but the update problem is the only issue i need to solve. Is there any possible way to have all elements in the list of objects being updated by the while loop? i have tried for many days and i have not been able to find a good solution. any ideas are appreciated. Thanks

• How to implement a Linked List in Java?

  - by nbarraille

  Hello! I am trying to implement a simple HashTable in Java that uses a Linked List for collision resolution, which is pretty easy to do in C, but I don't know how to do it in Java, as you can't use pointers... First, I know that those structures are already implemented in Java, I'm not planning on using it, just training here... So I created an element, which is a string and a pointer to the next Element: public class Element{ private String s; private Element next; public Element(String s){ this.s = s; this.next = null; } public void setNext(Element e){ this.next = e; } public String getString(){ return this.s; } public Element getNext(){ return this.next; } @Override public String toString() { return "[" + s + "] => "; } } Of course, my HashTable has an array of Element to stock the data: public class CustomHashTable { private Element[] data; Here is my problem: For example I want to implement a method that adds an element AT THE END of the linked List (I know it would have been simpler and more efficient to insert the element at the beginning of the list, but again, this is only for training purposes). How do I do that without pointer? Here is my code (which could work if e was a pointer...): public void add(String s){ int index = hash(s) % data.length; System.out.println("Adding at index: " + index); Element e = this.data[index]; while(e != null){ e = e.getNext(); } e = new Element(s); } Thanks!

• Having trouble deleting a node from a linked list

  - by Requiem

  I've been working on this code for my shell that I'm creating and for some reason it isn't working. I'm implementing a watchuser function that watch's a user when an argument is given (args[1]). However, when a second argument (args[2]) of "off" is given, the user should be deleted from the linked list and should no longer be watched. struct userList * goList; goList = userInventory; do{ if (strcmp(userInventory->username, args[1]) == 0){ printf("%s\n", args[1]); printf("%s\n",userInventory->username); struct userList * temp2; temp2 = userInventory->next; if (userInventory->next != NULL){ userInventory->next = temp2->next; userInventory->next->prev = userInventory; } free(temp2); } goList = goList->next; }while (goList != userInventory); My global struct is also as follows: struct userList{ char * username; struct userList * prev; struct userList * next; } For reason, this code won't delete the user node from my linked list. The adding works, but this remove function won't and I'm not sure why. The print statements are there just to make sure it's executing the condition, which it is. If anyone could help me find the reasoning behind my error, I'd greatly appreciate it. Till then, I'll be trying to debug this. Thanks.

• Display problem after deletion in linked list in C

  - by LuckySlevin

  Hi, actually this was another problem but it changed so I decided to open a new question. My code is typedef struct inner_list { int count; char word[100]; inner_list*next; } inner_list; typedef struct outer_list { char word [100]; inner_list * head; int count; outer_list * next; } outer_list; void delnode(outer_list **head,char num[100])//thanks to both Nir Levy and Jeremy P. { outer_list *temp, *m; m=temp=*head; /*FIX #1*/ while(temp!=NULL) { if(strcmp(temp->word,num)==0) { if(temp==*head) { delinner(temp->head); /* FIX#2 */ *head=temp->next; free(temp); return; } else { delinner(temp->head); /* FIX#2 */ m->next=temp->next; free(temp); return; } } else { m=temp; temp= temp->next; } } printf(" ELEMENT %s NOT FOUND ", num); } void delinner(inner_list *head) { /* FIX#2 */ inner_list *temp; temp=head; while(temp!=NULL) { head=temp->next; free(temp); temp=head; } } void delnode2(outer_list *up,inner_list **head,char num[100]) { inner_list *temp2,*temp, *m; outer_list *p; p = up; while(p!=NULL){m=temp=temp2=p->head; while(temp!=NULL) { if(strcmp(temp->word,num)==0) { if(temp==(*head)) { *head=temp->next; free(temp); return; } else { m->next=temp->next; free(temp); return; } } else { m=temp; temp= temp->next; } } p=p->next; } printf(" ELEMENT %s NOT FOUND ", num); } void print_node(outer_list *parent_node) { while(parent_node!=NULL){ printf("%s\t%d\t", parent_node->word, parent_node->count); inner_list *child_node = parent_node->head; printf("list: "); if(child_node ==NULL){printf("BUARADA");} while (child_node != NULL) { printf("%s-%d", child_node->word,child_node->count); child_node = child_node->next; if (child_node != NULL) { printf("->"); } } printf("\n"); parent_node = parent_node->next; } } While deleting an element from outer list I am also trying the delete the same element from inner_list too. For example: - Let's say aaa is an element of outer_list linked list and let's point it with outer_list *p - This aaa can also be in an inner_list linked list too. (it can be in p-head or another innerlist.) Now, the tricky part again. I tried to apply the same rules with outer_list deletion but whenever i delete the head element of inner_list it gives an error. Where is the wrong thing in print_node or delnode2?

• How to export and import an user profile from one Quassel core to another?

  - by Zertrin

  I have been using Quassel as my bouncer for IRC for quite a long time now. We (a group of administrators of a small network) have set up a shared Quassel core with many users on the same core. But now I would like to export everything related to my user account from the Quassel database on this core, in order to re-import it later in another Quassel core on my own server. Unfortunately, while a feature for adding users has been implemented into Quassel, nothing is so far provided for either exporting or deleting an user. (if deleting-a-user feature was available, I could have made a copy of the current database, delete all the other users leaving only mine, and use this resulting database on my own server, while leaving the first one untouched on the shared server) Despite extensive research on the Internet on this subject, I've found so far no solution. I have to precise that the backend database for the core has been migrated from the default SQLite backend to a PosgreSQL backend as the database grew sensibly (over 1,5 GB for now). However I'd be glad to hear from any working solution (SQLite or PostgreSQL backend) describing a way to export the data related to a specific user profile and then re-import-it in a new Quasselcore database.

• Handle Union of List in C# with duplicates

  Hi, I am trying to understand how to handle union or merge of two lists that can have duplicates. For example, List1 has { A, B, C} and List2 has { B, C, D }. I tried to use the Union operation and got a new list with values (A, B, C, D}. However, I need the B & C values from the second list, not first one. Is there a way to specify the union method, which duplicate value to use. The code I am using now is var newList = List1.Union<Object>(List2).ToList(); Thanks for any help. Javid

• Probability algorithm: Finding probable correct item in a list (e.g John, John, Jon)

First (and good!) attempt: MostFrequentItem(L).Count / L.Count (e.g. 4/5 or 80% likelihood) But consider the cases: John, John, Jon, Jonny John, John, Jon, Jon I want to consider the likelihood of the correct item being John to be higher in the first list!

• Is there a list of known web crawlers?

  - by J. Pablo Fernández

  I'm trying to get accurate download numbers for some files on a web server. I look at the user agents and some are clearly bots or web crawlers, but many for many I'm not sure, they may or may not be a web crawler and they are causing many downloads so it's important for me to know. Is there somewhere a list of know web crawlers with some documentation like user agent, IPs, behavior, etc? I'm not interested in the official ones, like Google's, Yahoo's, or Microsoft's. Those are generally well behaved and self-indentified.

• Python: Inheritance of a class attribute (list)

  - by Sano98

  Hi everyone, inheriting a class attribute from a super class and later changing the value for the subclass works fine: class Unit(object): value = 10 class Archer(Unit): pass print Unit.value print Archer.value Archer.value = 5 print Unit.value print Archer.value leads to the output: 10 10 10 5 which is just fine: Archer inherits the value from Unit, but when I change Archer's value, Unit's value remains untouched. Now, if the inherited value is a list, the shallow copy effect strikes and the value of the superclass is also affected: class Unit(object): listvalue = [10] class Archer(Unit): pass print Unit.listvalue print Archer.listvalue Archer.listvalue[0] = 5 print Unit.listvalue print Archer.listvalue Output: 10 10 5 5 Is there a way to "deep copy" a list when inheriting it from the super class? Many thanks Sano
