  • Add new item to UITableView and Core Data as data source?

    - by David.Chu.ca
    I have trouble to add new item to my table view with core data. Here is the brief logic in my codes. In my ViewController class, I have a button to trigle the edit mode: - (void) toggleEditing { UITableView *tv = (UITableView *)self.view; if (isEdit) // class level flag for editing { self.newEntity = [NSEntityDescription insertNewObjectForEntityName:@"entity1" inManagedObjectContext:managedObjectContext]; NSArray *insertIndexPaths = [NSArray arrayWithObjects: [NSInextPath indexPathForRow:0 inSection:0], nil]; // empty at beginning so hard code numbers here. [tv insertRowsAtIndexPaths:insertIndexPaths withRowAnimation:UITableViewRowAnimationFade]; [self.tableView setEditing:YES animated:YES]; // enable editing mode } else { ...} } In this block of codes, I added a new item to my current managed object context first, and then I added a new row to my tv. I think that both the number of objects in my data source or context and the number of rows in my table view should be 1. However, I got an exception in the event of tabView:numberOfRowsInSection: Invalid update: invalid number of rows in section 0. The number of rows contained in an existing section after the update (0) must be equal to the number of rows contained in that section before the update (0), plus or minus the number of rows inserted or deleted from that section (1 inserted, 0 deleted). The exception was raised right after the delegate event: - (NSInteger) tableView:(UITableView *) tableView numberOfRawsInSection:(NSInteger) section { // fetchedResultsController is class member var NSFetchedResultsController id <NSFechedResultsSectionInfo> sectionInfo = [[fetchedResultsController sections] objectAtIndex: section]; NSInteger rows = [sectionInfo numberOfObjects]; return rows; } In debug mode, I found that the rows was still 0 and the event invoked after the the even of toggleEditing. It looks like that sectionInfo obtained from fetchedResultsController did not include the new entity object inserted. Not sure if I miss anything or steps? I am not sure how it works: to get the fetcedResultsController notified or reflect the change when a new entity is inserted into the current managed object context?

  • Editing Django's admin index <div id='module'> tag

    - by zen
    I am new to the Django framework. On Django's admin index page I'd like to get rid of the "s" at the end of my model names. Example: <div class="module"> <table summary="Models available in the my application."> <caption><a href="" class="section">My application</a></caption> <tr> <th scope="row"><a href="model/">Model**s**</a></th> <td><a href="model/add/" class="addlink">Add</a></td> <td><a href="model/" class="changelink">Change</a></td> </tr> </table> </div> I know of a way to do this but I am really looking for the file I should edit. Where is it and what exactly should I do? I can't seem to pinpoint where it is coming from.

  • Account Lockout with pam_tally2 in RHEL6

    - by Aaron Copley
    I am using pam_tally2 to lockout accounts after 3 failed logins per policy, however, the connecting user does not receive the error indicating pam_tally2's action. (Via SSH.) I expect to see on the 4th attempt: Account locked due to 3 failed logins No combination of required or requisite or the order in the file seems to help. This is under Red Hat 6, and I am using /etc/pam.d/password-auth. The lockout does work as expected but the user does not receive the error described above. This causes a lot of confusion and frustration as they have no way of knowing why authentication fails when they are sure they are using the correct password. Implementation follows NSA's Guide to the Secure Conguration of Red Hat Enterprise Linux 5. (pg.45) It's my understanding that that only thing changed in PAM is that /etc/pam.d/sshd now includes /etc/pam.d/password-auth instead of system-auth. If locking out accounts after a number of incorrect login attempts is required by your security policy, implement use of pam_tally2.so. To enforce password lockout, add the following to /etc/pam.d/system-auth. First, add to the top of the auth lines: auth required pam_tally2.so deny=5 onerr=fail unlock_time=900 Second, add to the top of the account lines: account required pam_tally2.so EDIT: I get the error message by resetting pam_tally2 during one of the login attempts. user@localhost's password: (bad password) Permission denied, please try again. user@localhost's password: (bad password) Permission denied, please try again. (reset pam_tally2 from another shell) user@localhost's password: (good password) Account locked due to ... Account locked due to ... Last login: ... [user@localhost ~]$

  • Autonumber with Entity Framework

    - by dcompiled
    I want to loop through a collection of objects and add them all to a table. The destination table has an auto-increment field. If I add a single object there is no problem. If I add two objects both with the primary key of zero, the entity framework fails. I can manually specify primary keys but the whole point of trying the EF was to make life easier not more complicated. Here is the code and the exception received follows. foreach (Contact contact in contacts) { Instructor instructor = InstructorFromContact(contact); context.AddToInstructors(instructor); } try { context.SaveChanges(); } catch (Exception ex) { Console.WriteLine(ex.ToString()); } System.InvalidOperationException: The changes to the database were committed successfully, but an error occurred while updating the object context. The ObjectContext might be in an inconsistent state. Inner exception message: AcceptChanges cannot continue because the object's key values conflict with another object in the ObjectStateManager. Make sure that the key values are unique before calling AcceptChanges. at System.Data.Objects.ObjectContext.SaveChanges(SaveOptions options) at System.Data.Objects.ObjectContext.SaveChanges() at DataMigration.Program.CopyInstructors() in C:\Projects\DataMigration\Program.cs:line 52

  • ActiveSync devices causing accounts to lockout

    - by Abdullah
    When a user changes his account password for whatever reason (read: expired), and the old password is stored in his mobile device connected through EAS. This will cause his account almost immediately - as it should according to the lockout policy defined in the AD. It was easy to figure out that part. The hard part is keeping it from happening. I looked everywhere. Nothing. Basically there are four parts to the puzzle: the EAS device, the TMG (ISA) server, the EAS protocol and finally the AD. None of them have a way to stop the EAS device from failing to authenticate. So I figured I'll have to come up with a clever workaround. And the only thing I could come up with is to create a group for all EAS users and exclude them from the lockout policy, which obviously defeats the whole purpose of the policy, or to educate the users to update their devices with the new passwords, which is impossible. The question: Can you think of any other way to prevent EAS from locking out the accounts? Environment: Mostly iOS devices all through EAS. TMG 2010. Exchange 2007. AD 2008 R2.

  • HTML Agility Pack Screen Scraping XPATH isn't returning data

    - by Matthias Welsh
    I'm attempting to write a screen scraper for Digikey that will allow our company to keep accurate track of pricing, part availability and product replacements when a part is discontinued. There seems to be a discrepancy between the XPATH that I'm seeing in Chrome Devtools as well as Firebug on Firefox and what my C# program is seeing. The code I'm currently using is pretty quick and dirty... //This function retrieves data from the digikey private static List<string> ExtractProductInfo(HtmlDocument doc) { List<HtmlNode> m_unparsedProductInfoNodes = new List<HtmlNode>(); List<string> m_unparsedProductInfo = new List<string>(); //Base Node for part info string m_baseNode = @"//html[1]/body[1]/div[2]"; //Write part info to list m_unparsedProductInfoNodes.Add(doc.DocumentNode.SelectSingleNode(m_baseNode + @"/table[1]/tr[1]/td[1]/table[1]/tr[1]/td[1]")); //More lines of similar form will go here for more info //this retrieves digikey PN foreach(HtmlNode node in m_unparsedProductInfoNodes) { m_unparsedProductInfo.Add(node.InnerText); } return m_unparsedProductInfo; } Although the path I'm using appears to be "correct" I keep getting NULL when I look at the list "m_unparsedProductInfoNodes" Any idea what's going on here? I'll also add that if I do a "SelectNodes" on the baseNode it only returns a div... not sure what that indicates but it doesn't seem right.

  • ASP.NET AJAX Toolkit - CalendarExtender is reset on Postback

    - by user70192
    Hello, I have an ASP.NET page that has two input elements: A TextBox that is ReadOnly. This TextBox is the TargetControl of a CalendarExtender A DropDownList with AutoPostBack=true Here is the code: <table border="0" cellpadding="0" cellspacing="0"> <tr><td colspan="2">Date:</td></tr> <tr><td colspan="2"> <asp:TextBox ID="dateTextBox" runat="server" ReadOnly="true" /> <ajax:CalendarExtender ID="datePicker" runat="server" Format="MM/dd/yyyy" OnLoad="datePicker_Load" TargetControlID="dateTextBox" /> </td></tr> <tr><td colspan="2">Select an Option:</td></tr> <tr> <td>Name:&nbsp;</td> <td><asp:DropDownList ID="optionsDropDownList" runat="server" AutoPostBack="true" OnLoad="optionsDropDownList_Load" OnSelectedIndexChanged="optionsDropDownList_SelectedIndexChanged" DataTextField="Name" DataValueField="ID" /> </td></tr> <tr><td><asp:Button ID="saveButton" runat="server" Text="Save" OnClick="saveButton_Click" /></td></tr> </table> When the DropDownList posts back, the date selected by the user with the datePicker is reset to the current date. In addition, if I look at the Text property of dateTextBox, it is equal to string.Empty. How do I preserve the date that the user selected on a PostBack?

  • Sql Query - Limiting query results

    - by Gublooo
    I am quite certain we cannot use the LIMIT clause for what I want to do - so wanted to find if there are any other ways we can accomplish this. I have a table which captures which user visited which store. Every time a user visits a store, a row is inserted into this table. Some of the fields are shopping_id (primary key) store_id user_id Now what I want is - for a given set of stores, find the top 5 users who have visited the store max number of times. I can do this 1 store at a time as: select store_id,user_id,count(1) as visits from shopping where store_id = 60 group by user_id,store_id order by visits desc Limit 5 This will give me the 5 users who have visited store_id=60 the max times What I want to do is provide a list of 10 store_ids and for each store fetch the 5 users who have visited that store max times select store_id,user_id,count(1) as visits from shopping where store_id in (60,61,62,63,64,65,66) group by user_id,store_id order by visits desc Limit 5 This will not work as the Limit at the end will return only 5 rows rather than 5 rows for each store. Any ideas on how I can achieve this. I can always write a loop and pass 1 store at a time but wanted to know if there is a better way

  • Problem with cascade delete using Entity Framework and System.Data.SQLite

    - by jamone
    I have a SQLite DB that is set up so when I delete a Person the delete is cascaded. This works fine when I manually delete a Person (all records that reference the PersonID are deleted). But when I use Entity Framework to delete the Person I get an error: System.InvalidOperationException: The operation failed: The relationship could not be changed because one or more of the foreign-key properties is non-nullable. When a change is made to a relationship, the related foreign-key property is set to a null value. If the foreign-key does not support null values, a new relationship must be defined, the foreign-key property must be assigned another non-null value, or the unrelated object must be deleted. I don't understand why this is occurring. My trigger is set to clean up all related objects before deleting the object it was told to delete. When I go into the model editor and check the properties of the relationship it shows no action for the OnDelete property. Why isn't this set correctly by pulling it from the DB? If I change this value to Cascade everything works properly, but I would rather not rely on this manual change because what if I refresh my model from the DB and it looses that. Here's the relivent SQL for my tables. CREATE TABLE [SomeTable] ( [SomeTableID] INTEGER NOT NULL PRIMARY KEY AUTOINCREMENT, [PersonID] INTEGER NOT NULL REFERENCES [Person](PersonID) ON DELETE CASCADE ) CREATE TABLE [Person] ( [PersonID] INTEGER NOT NULL PRIMARY KEY AUTOINCREMENT )

  • SSTP BPDU with bad TLV and macflap -- info please

    Hi All, I'm slowly locking down the network I've inherited and mac-flapping has been a problem in the past with customers doing all kinds of crazy things. Thats changing but I am now encountering this error: Dec 30 18:31:31 10.50.1.50 1565: 001567: Dec 30 18:31:30: %SW_MATM-4-MACFLAP_NOTIF: Host xxxx.xxxx.f681 in vlan 1 is flapping between port Gi0/5 and port Gi0/48 Dec 30 18:43:28 10.50.1.50 1566: 001568: Dec 30 18:43:26: %SPANTREE-2-RECV_BAD_TLV: Received SSTP BPDU with bad TLV on GigabitEthernet0/5 VLAN1.

What else could be going on with these messages ... the bad TLV is a new one for me. Any ideas? Thank you and Happy New Year to you all!!

  • "If not exists" fails on SQL CE

    - by Mark Evans
    Hi I've got an unexpected problem. I'm making a script to update the schema on a SQL CE database. This won't run: if not exists ( Select column_name from information_schema.columns where column_name = 'TempTestField' and table_name = 'Inventory_Master_File' ) Alter table Inventory_Master_File add TempTestField nvarchar(10) null I think this is because I'm using stuff that isn't supported in SQL CE. Anyone know how to do this? I've tried rearranging the script and can't get anything to work. I tried "alter table ... where not exists ...". Note that the "select" part runs fine and also the "alter" part. The problem is "if not exists". I know there are some other postings regarding problems like this using SQL CE but I couldn't find an answer to this particular problem. Cheers Mark UPDATE: I've spent over an hour looking for a solution. I've found many postings asking for help with similar problems but I've still got no idea how to fix it. I really don't want to do this in C# code. I need to do this in a SQL script. I can't believe something this basic is causing so much difficulty :(

  • spring-mvc binding arraylist in form

    - by Mike
    In my controller I added an ArrayList to my model with the attribute name "users". Now I looked around and this is the method I found (including a question here): <form:form action="../user/edit" method="post" modelAttribute="users"> <table> <c:forEach var="user" items="${users}" varStatus="counter"> <tr> <td> <form:input path="users[${counter.index}].age"/> </td> <td><button type="submit" name="updateId" id="Update" value="${user.id}">Update</button></td> </tr> </c:forEach> </table> </form:form> But when I load the JSP page I get: .springframework.beans.NotReadablePropertyException: Invalid property 'projects[0]' of bean class [java.util.ArrayList]: Bean property 'users[0]' is not readable or has an invalid getter method: Does the return type of the getter match the parameter type of the setter? So apparantely this isn't the way to go, but in that case how do I bind an arraylist so I can edit the values?

  • MVC Checkbox List

  • Error using Dynamic Data Filtering: missing datasource

    - by sebastiaan
    I am trying to use the ASP.NET Dynamic Data Filtering project, but I'm running into a problem during the configuration. I'm following the instructions on the author's blog, and everything works like described. Then it tells me to change the datasource using the designer view. I am told to select the "GridDataSource" in the "Configure data source" wizard. This option is not there though. I get all of the classes in my project, including the DataContext that was generated by Linq. When I choose "Show only DataContext objects", the dropdown ("Choose your context object:") is completely empty. When I turn of the checkbox and choose my DataContext class, I get asked which table I want and all that. But, as the whole purpose of a Dynamic Data site is NOT to use one single table, that's not much help. So I've looked at the instructions again and copied the resulting datasource from the example: <asp:DynamicLinqDataSource ID="GridDataSource" runat="server" EnableDelete="True" EnableUpdate="True"></asp:DynamicLinqDataSource> Which is exactly what I had, without the "WhereParameters" nodes in there. Now, when I run the list page however, I get an exception about a missing datasource from the filtering component. Of course when I remove the DynamicFilterRepeater, it works again. This is the meat of the exception: [InvalidOperationException: Missing DataSource] Catalyst.Web.DynamicData.DynamicFilterRepeater.GetTable() in D:\Catalyst\Projects\DynamicData\Project\Trunk\DynamicData\DynamicData\DynamicFilterRepeater.cs:74 Catalyst.Web.DynamicData.DynamicFilterRepeater.GetFilters() in D:\Catalyst\Projects\DynamicData\Project\Trunk\DynamicData\DynamicData\DynamicFilterRepeater.cs:81 Catalyst.Web.DynamicData.DynamicFilterRepeater.OnInit(EventArgs e) in D:\Catalyst\Projects\DynamicData\Project\Trunk\DynamicData\DynamicData\DynamicFilterRepeater.cs:106 How do I make the DynamicFilterRepeater recognize my datasource?

  • LINQ to Entity, using a SQL LIKE operator

    - by Mario
    I have a LINQ to ENTITY query that pulls from a table, but I need to be able to create a "fuzzy" type search. So I need to add a where clause that searches by lastname IF they add the criteria in the search box (Textbox, CAN be blank --- in which case it pulls EVERYTHING). Here is what I have so far: var query = from mem in context.Member orderby mem.LastName, mem.FirstName select new { FirstName = mem.FirstName, LastName = mem.LastName, }; That will pull everything out of the Member table that is in the Entity object. Then I have an addition to the logic: sLastName = formCollection["FuzzyLastName"].ToString(); if (!String.IsNullOrEmpty(sLastName)) query = query.Where(ln => ln.LastName.Contains(sLastName)); The problem is when the search button is pressed, nothing is returned (0 results). I have run the query against the SQL Server that I expect to happen here and it returns 6 results. This is the query I expect: SELECT mem.LastName, mem.FirstName FROM Members mem WHERE mem.LastName = 'xxx' (when xxx is entered into the textbox) Anyone see anything wrong with this?

  • Unicode Collations problem ?

    - by Bayonian
    (.NET 3.5 SP1, VS 2008, VB.NET, MSSQL Server 2008) I'm writing a small web app to test the Khmer Unicode and Lao Unicode. I have a table that store text in Khmer Unicode with the following structure : [t_id] [int] IDENTITY(1,1) NOT NULL [t_chid] [int] NOT NULL [t_vn] [int] NOT NULL [t_v] [nvarchar](max) NOT NULL I can use Linq to SQL to do CRUD normally. The text display properly on the web page, even though I didn't change the default collation of MSSQL Server 2008. When it comes to search the column [t_v], the page will take a very long time to load and in fact, it loads every row of that column. It never compares with the "key word" criteria that I use for the search. Here's my query for the search : Public Shared Function SearchTestingKhmerTable(ByVal keyword As String) As DataTable Dim db As New BibleDataClassesDataContext() Dim query = From b In db.khmer_books _ From ch In db.khmer_chapters _ From v In db.testing_khmers _ Where v.t_v.Contains(keyword) And ch.kh_book_id = b.kh_b_id And v.t_chid = ch.kh_ch_id _ Select b.kh_b_id, b.kh_b_title, ch.kh_ch_id, ch.kh_ch_number, v.t_id, v.t_vn, v.t_v Dim dtDataTableOne = New DataTable("dtOne") dtDataTableOne.Columns.Add("bid", GetType(Integer)) dtDataTableOne.Columns.Add("btitle", GetType(String)) dtDataTableOne.Columns.Add("chid", GetType(Integer)) dtDataTableOne.Columns.Add("chn", GetType(Integer)) dtDataTableOne.Columns.Add("vid", GetType(Integer)) dtDataTableOne.Columns.Add("vn", GetType(Integer)) dtDataTableOne.Columns.Add("verse", GetType(String)) For Each r In query dtDataTableOne.Rows.Add(New Object() {r.kh_b_id, r.kh_b_title, r.kh_ch_id, r.kh_ch_number, r.t_id, r.t_vn, r.t_v}) Next Return dtDataTableOne End Function Please note that I use the exact same code and database design with Lao Unicode and it works just fine. I get the returned query as expected for the search. I can't figure out what the problem with searching for query in Khmer table.

  • How to prevent duplicate records being inserted with SqlBulkCopy when there is no primary key

    - by kscott
    I receive a daily XML file that contains thousands of records, each being a business transaction that I need to store in an internal database for use in reporting and billing. I was under the impression that each day's file contained only unique records, but have discovered that my definition of unique is not exactly the same as the provider's. The current application that imports this data is a C#.Net 3.5 console application, it does so using SqlBulkCopy into a MS SQL Server 2008 database table where the columns exactly match the structure of the XML records. Each record has just over 100 fields, and there is no natural key in the data, or rather the fields I can come up with making sense as a composite key end up also having to allow nulls. Currently the table has several indexes, but no primary key. Basically the entire row needs to be unique. If one field is different, it is valid enough to be inserted. I looked at creating an MD5 hash of the entire row, inserting that into the database and using a constraint to prevent SqlBulkCopy from inserting the row,but I don't see how to get the MD5 Hash into the BulkCopy operation and I'm not sure if the whole operation would fail and roll back if any one record failed, or if it would continue. The file contains a very large number of records, going row by row in the XML, querying the database for a record that matches all fields, and then deciding to insert is really the only way I can see being able to do this. I was just hoping not to have to rewrite the application entirely, and the bulk copy operation is so much faster. Does anyone know of a way to use SqlBulkCopy while preventing duplicate rows, without a primary key? Or any suggestion for a different way to do this?

  • UISearchBar delegate not called when used as UINavigationBar titleVIew?

    - by phooze
    I have a UITableViewController that I have specified as a UISearchBarDelegate. Up until now, I had programmatically added the UISearchBar to the headerView of the table, and there were no problems. I began to run out of screen real estate, so I decided to kill my normal UINavigationController title (which was text), and added the following code, moving my SearchBar from the table to the UINavigationBar: // (Called in viewDidLoad) // Programmatically make UISearchBar UISearchBar *tmpSearchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0,0,320,45)]; tmpSearchBar.delegate = self; tmpSearchBar.showsCancelButton = YES; tmpSearchBar.autocorrectionType = UITextAutocorrectionTypeNo; tmpSearchBar.autocapitalizationType = UITextAutocapitalizationTypeNone; [self set_searchBar:tmpSearchBar]; [tmpSearchBar release]; self.navigationItem.titleView = [self _searchBar]; This code works as expected - my UINavigationBar is now a UISearchBar. However, my delegate method: /** Only show the cancel button when the keyboard is displayed */ - (void) searchBarDidBeginEditing:(UISearchBar*) lclSearchBar { lclSearchBar.showsCancelButton = YES; } ...is no longer being called. I've breakpointed, and I've confirmed that the UISearchBar's delegate is indeed self, the view controller. Oddly, this delegate method is still called just fine: /** Run the search and resign the keyboard */ - (void) searchBarSearchButtonClicked:(UISearchBar *)lclSearchBar { _deepSearchRan = NO; [self runSearchForString:[[self _searchBar] text] isSlowSearch:NO]; [lclSearchBar resignFirstResponder]; } Any ideas why UINavigationBar is swallowing my delegate calls?? What am I missing?
