  • Chartfx new chart object not initialized?

    - by Roy
    When I create a new chart object via: ChartFX.WebForms.Chart theChart = new ChartFX.WebForms.Chart(); When I took a look immediately the row after creation via breakpoint in Visual Studio 2005 I noticed there are 3 rows in the newly created chart that have data. Is this a bug? or do I need to call a specific function? Shouldn't the data table for the chart be initialized to all 0's?

  • Packing differently sized chunks of data into multiple bins

    - by knizz
    EDIT: It seems like this problem is called "Cutting stock problem" I need an algorithm that gives me the (space-)optimal arrangement of chunks in bins. One way would be put the bigger chunks in first. But see how that algorithm fails in this example: Chunks Bins ----------------------------- AAA BBB CC DD ( ) ( ) Algorithm Result ----------------------------- biggest first (AAABBB ) (CC ) optimal (AAACCDD) (BBB) "Biggest first" can't fit in DD. Maybe it helps to build a table like this: Size 1: --- Size 2: CC, DD Size 3: AAA, BBB Size 4: CCDD Size 5: AAACC, AAADD, BBBCC, BBBDD Size 6: AAABBB Size 7: AAACCDD, BBBCCDD Size 8: AAABBBCC, AAABBBDD Size 10: AAABBBCCDD

  • Setting the AccountController in ASP.NET MVC 1.0 Template Not to Connect to SQL Server Express

    - by Maxim Z.
    I'm writing a website in ASP.NET MVC, using the ASP.NET MVC 1.0 template that was added to VS2008 for me by the ASP.NET MVC installer. The template automatically adds an AccountController, but its account methods tie into a SQL Server Express entity. I don't have Express installed here. How can I reconfigure it to use my SQL Server 2008 database and to store user info in some columns in a User table I've already created?

  • I need to unset the state of the jQuery .toggle(odd,even)

    - by Forkrul Assail
    Hi I have items in a table cell that gets toggled on and off. An external button accepts a click and submits the selected cell values via ajax. The problem is that I want to reset the toggle state for the selected cells. I can easily unset the highlighting, but then need a double click to trigger the correct toggle. Can the .toggle(odd, even) be reset or cycled via an external call? Thanks

  • Updating UISearchDisplayController with Core Data results using GCD

    - by Brian Halpin
    I'm having trouble displaying the results from Core Data in my UISearchDisplayController when I implement GCD. Without it, it works, but obviously blocks the UI. In my SearchTableViewController I have the following two methods: - (BOOL)searchDisplayController:(UISearchDisplayController *)controller shouldReloadTableForSearchString:(NSString *)searchString { // Tell the table data source to reload when text changes [self filterContentForSearchText:searchString]; // Return YES to cause the search result table view to be reloaded. return YES; } // Update the filtered array based on the search text -(void)filterContentForSearchText:(NSString*)searchText { // Remove all objects from the filtered search array [self.filteredLocationsArray removeAllObjects]; NSPredicate *predicate = [CoreDataMaster predicateForLocationUsingSearchText:@"Limerick"]; CoreDataMaster *coreDataMaster = [[CoreDataMaster alloc] init]; // Filter the array using NSPredicate self.filteredLocationsArray = [NSMutableArray arrayWithArray: [coreDataMaster fetchResultsFromCoreDataEntity:@"City" UsingPredicate:predicate]]; } You can probably guess that my problem is with returning the array from [coreDataMaster fetchResultsFromCoreDataEntity]. Below is the method: - (NSArray *)fetchResultsFromCoreDataEntity:(NSString *)entity UsingPredicate:(NSPredicate *)predicate { NSMutableArray *fetchedResults = [[NSMutableArray alloc] init]; dispatch_queue_t coreDataQueue = dispatch_queue_create("com.coredata.queue", DISPATCH_QUEUE_SERIAL); dispatch_async(coreDataQueue, ^{ NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init]; NSEntityDescription *entityDescription = [NSEntityDescription entityForName:entity inManagedObjectContext:self.managedObjectContext]; NSSortDescriptor *nameSort = [[NSSortDescriptor alloc] initWithKey:@"name" ascending:YES]; NSArray *sortDescriptors = [NSArray arrayWithObjects:nameSort, nil]; [fetchRequest setEntity:entityDescription]; [fetchRequest setSortDescriptors:sortDescriptors]; // Check if predicate is set if (predicate) { [fetchRequest setPredicate:predicate]; } NSError *error = nil; NSArray *fetchedManagedObjects = [self.managedObjectContext executeFetchRequest:fetchRequest error:&error]; for (City *city in fetchedManagedObjects) { [fetchedResults addObject:city]; } NSDictionary *userInfo = [NSDictionary dictionaryWithObject:[NSArray arrayWithArray:fetchedResults] forKey:@"results"]; [[NSNotificationCenter defaultCenter] postNotificationName:@"fetchResultsComplete" object:nil userInfo:userInfo]; }); return [NSArray arrayWithArray:fetchedResults]; } So the thread hasn't finished executing by the time it returns the results to self.filteredLocationsArray. I've tried added a NSNotification which passes the NSDictionary to this method: - (void)updateSearchResults:(NSNotification *)notification { NSDictionary *userInfo = notification.userInfo; NSArray *array = [userInfo objectForKey:@"results"]; self.filteredLocationsArray = [NSMutableArray arrayWithArray:array]; [self.tableView reloadData]; } I've also tried refreshing the searchViewController like [self.searchDisplayController.searchResultsTableView reloadData]; but to no avail. I'd really appreciate it if someone could point me in the right direction and show me where I might be going wrong. Thanks

  • how to handle a array of objects in a session

    - by Robert
    Hello, In the project I'm working on I have got a list List<Item> with objects that Is saved in a session. Session.Add("SessionName", List); In the Controller I build a viewModel with the data from this session var arrayList = (List<Item>)Session["SessionName"]; var arrayListItems= new List<CartItem>(); foreach (var item in arrayList) { var listItem = new Item { Amount = item.Amount, Variant= item.variant, Id = item.Id }; arrayListItems.Add(listItem); } var viewModel = new DetailViewModel { itemList = arrayListItems } and in my View I loop trough the list of Items and make a form for all of them to be able to remove the item. <table> <%foreach (var Item in Model.itemList) { %> <% using (Html.BeginForm()) { %> <tr> <td><%=Html.Hidden(Settings.Prefix + ".VariantId", Item .Variant.Id)%> <td> <%=Html.TextBox(Settings.Prefix + ".Amount", Item.Amount)%></td> <td> <%=Html.Encode(Item.Amount)%> </td> <td> <input type="submit" value="Remove" /> </td> </tr> <% } %> <% } %> </table> When the post from the submit button is handeld the item is removed from the array and post back exactly the same viewModel (with 1 item less in the itemList). return View("view.ascx", viewModel); When the post is handled and the view has reloaded the value's of the html.Hidden and Html.Textbox are the value's of the removed item. The value of the html.Encode is the correct value. When i reload the page the correct values are in the fields. Both times i build the viewModel the exact same way. I cant find the cause or solution of this error. I would be very happy with any help to solve this problem Thanx in advance for any tips or help

    I have a small database with tables containing a small amount of data which I need to copy into memory. Currently I am using: insertcommand.CommandText = "SELECT sql FROM sqlite_master WHERE sql NOT NULL;"; To pull all the table schema from the file database, however I'm not really sure how to proceed with creating these tables in the new memory database, and copying all the relevant data across. In short, how do I copy an SQLite database from file to memory using C# and System.Data.SQLite?

  • Find Specific Rows

    - by H07R0D
    I'm trying to build a rather specific query to find a set of user_ids based on topics they have registered to. Unfortunately it's not possible to refactor the tables so I have to go with what I've got. Single table with user_id and registration_id I need to find all user_ids that have a registration_id of (4 OR 5) AND NOT 1 Each row is a single user_id/registration_id combination. My SQL skills aren't the best, so I'm really scratching my brain. Any help would be greatly appreciated.

  • What to name 2 methods with same signatures

    - by coffeeaddict
    Initially I had a method in our DL that would take in the object it's updating like so: internal void UpdateCash(Cash Cash) { using (OurCustomDbConnection conn = CreateConnection("UpdateCash")) { conn.CommandText = @"update Cash set captureID = @captureID, ac_code = @acCode, captureDate = @captureDate, errmsg = @errorMessage, isDebit = @isDebit, SourceInfoID = @sourceInfoID, PayPalTransactionInfoID = @payPalTransactionInfoID, CreditCardTransactionInfoID = @CreditCardTransactionInfoID where id = @cashID"; conn.AddParam("@captureID", cash.CaptureID); conn.AddParam("@acCode", cash.ActionCode); conn.AddParam("@captureDate", cash.CaptureDate); conn.AddParam("@errorMessage", cash.ErrorMessage); conn.AddParam("@isDebit", cyberCash.IsDebit); conn.AddParam("@PayPalTransactionInfoID", cash.PayPalTransactionInfoID); conn.AddParam("@CreditCardTransactionInfoID", cash.CreditCardTransactionInfoID); conn.AddParam("@sourceInfoID", cash.SourceInfoID); conn.AddParam("@cashID", cash.Id); conn.ExecuteNonQuery(); } } My boss felt that creating an object every time just to update one or two fields is overkill. But I had a couple places in code using this. He recommended using just UpdateCash and sending in the ID for CAsh and field I want to update. Well the problem is I have 2 places in code using my original method. And those 2 places are updating 2 completely different fields in the Cash table. Before I was just able to get the existing Cash record and shove it into a Cash object, then update the properties I wanted to be updated in the DB, then send back the cash object to my method above. I need some advice on what to do here. I have 2 methods and they have the same signature. I'm not quite sure what to rename these because both are updating 2 completely different fields in the Cash table: internal void UpdateCash(int cashID, int paypalCaptureID) { using (OurCustomDbConnection conn = CreateConnection("UpdateCash")) { conn.CommandText = @"update Cash set CaptureID = @paypalCaptureID where id = @cashID"; conn.AddParam("@captureID", paypalCaptureID); conn.ExecuteNonQuery(); } } internal void UpdateCash(int cashID, int PayPalTransactionInfoID) { using (OurCustomDbConnection conn = CreateConnection("UpdateCash")) { conn.CommandText = @"update Cash set PaymentSourceID = @PayPalTransactionInfoID where id = @cashID"; conn.AddParam("@PayPalTransactionInfoID", PayPalTransactionInfoID); conn.ExecuteNonQuery(); } } So I thought hmm, maybe change the names to these so that they are now unique and somewhat explain what field its updating: UpdateCashOrderID UpdateCashTransactionInfoID ok but that's not really very good names. And I can't go too generic, for example: UpdateCashTransaction(int cashID, paypalTransactionID) What if we have different types of transactionIDs that the cash record holds besides just the paypalTransactionInfoID? such as the creditCardInfoID? Then what? Transaction doesn't tell me what kind. And furthermore what if you're updating 2 fields so you have 2 params next to the cashID param: UpdateCashTransaction(int cashID, paypalTransactionID, someOtherFieldIWantToUpdate) see my frustration? what's the best way to handle this is my boss doesn't like my first route?

  • MVC Entity Framework Model not returning correct data

    - by quagland
    Hi, Run into a strange problem while writing an ASP.NET MVC site. I have a view in my SQL Server database that returns a few date ranges. The view works fine when running the query in SSMS. When the view data is returned by the Entity Framework Model, It returns the correct number of rows but some of the rows are duplicated. Here is an example of what I have done: SQL Server code: CREATE TABLE [dbo].[A]( [ID] [int] NOT NULL, [PhID] [int] NULL, [FromDate] [datetime] NULL, [ToDate] [datetime] NULL, CONSTRAINT [PK_A] PRIMARY KEY CLUSTERED ([ID] ASC)) ON [PRIMARY] go CREATE TABLE [dbo].[B]( [PhID] [int] NOT NULL, [FromDate] [datetime] NULL, [ToDate] [datetime] NULL, CONSTRAINT [PK_B] PRIMARY KEY CLUSTERED ( [PhID] ASC )) ON [PRIMARY] go CREATE VIEW C as SELECT A.ID, CASE WHEN A.PhID IS NULL THEN A.FromDate ELSE B.FromDate END AS FromDate, CASE WHEN A.PhID IS NULL THEN A.ToDate ELSE B.ToDate END AS ToDate FROM A LEFT OUTER JOIN B ON A.PhID = B.PhID go INSERT INTO B (PhID, FromDate, ToDate) VALUES (100, '20100615', '20100715') INSERT INTO A (ID, PhID, FromDate, ToDate) VALUES (1, NULL, '20100101', '20100201') INSERT INTO A (ID, PhID, FromDate, ToDate) VALUES (1, 100, '20100615', '20100715') INSERT INTO B (PhID, FromDate, ToDate) VALUES (101, '20101201', '20101231') INSERT INTO A (ID, PhID, FromDate, ToDate) VALUES (2, NULL, '20100801', '20100901') INSERT INTO A (ID, PhID, FromDate, ToDate) VALUES (2, 101, '20101201', '20101231') So now, if you select all from C, you get 4 separate date ranges In the Entity Framework Model (which I call 'Core'), the view 'C' is added. in MVC Controller: public class HomeController : Controller { public ActionResult Index() { CoreEntities db = new CoreEntities(); var clist = from c in db.C select c; return View(clist.ToList()); } } in MVC View: @model List<RM.Models.C> @{ foreach (RM.Models.C c in Model) { @String.Format("{0:dd-MMM-yyyy}", c.FromDate) <span>-</span> @String.Format("{0:dd-MMM-yyyy}", c.ToDate) <br /> } } When I run all this, it outputs this: 01-Jan-2010 - 01-Feb-2010 01-Jan-2010 - 01-Feb-2010 01-Aug-2010 - 01-Sep-2010 01-Aug-2010 - 01-Sep-2010 When it should do this (this is what the view returns): 01-Jan-2010 - 01-Feb-2010 15-Jun-2010 - 15-Jul-2010 01-Aug-2010 - 01-Sep-2010 01-Dec-2010 - 31-Dec-2010 Also, I've run the SQL profiler over it and according to that, the query being executed is: SELECT [Extent1].[ID] AS [ID], [Extent1].[FromDate] AS [FromDate], [Extent1].[ToDate] AS [ToDate] FROM (SELECT [C].[ID] AS [ID], [C].[FromDate] AS [FromDate], [C].[ToDate] AS [ToDate] FROM [dbo].[C] AS [C]) AS [Extent1] Which returns the correct data So it seems that the entity framework is doing something to the data in the meantime. To me, everything looks fine! Have I missed something? Cheers, Ben
