  • SQL Stored Procedure fired from C# Code-Behind not working on UPDATE

    - by CSSHell
    I have a stored procedure called from a C# code-behind. The code fires but the update command does not get performed. The stored procedure, if run directly, works. I think I am having a brain fart. Please help. :) CODEBEHIND protected void btnAbout_Click(object sender, EventArgs e) { SqlConnection myConnection = new SqlConnection(strConnection); SqlCommand myCommand = new SqlCommand("spUpdateCMSAbout", myConnection); myConnection.Open(); myCommand.CommandType = CommandType.StoredProcedure; myCommand.Parameters.Add("@AboutText", SqlDbType.NVarChar, -1).Value = txtAbout.Text.ToString(); myCommand.ExecuteNonQuery(); myConnection.Close(); } STORED PROCEDURE ALTER PROCEDURE fstage.spUpdateCMSAbout ( @AboutText nvarchar(max) ) AS BEGIN SET NOCOUNT ON; UPDATE fstage.staticCMS SET About = @AboutText; END HTML <asp:Button ID="btnAbout" runat="server" Text="Save" CausesValidation="False" onclick="btnAbout_Click" UseSubmitBehavior="False" /> C# .NET 4.0

  • C#, Generic Lists and Inheritance

    - by Andy
    I have a class called Foo that defines a list of objects of type A: class Foo { List<A> Items = new List<A>(); } I have a class called Bar that can save and load lists of objects of type B: class Bar { void Save(List<B> ComplexItems); List<B> Load(); } B is a child of A. Foo, Bar, A and B are in a library and the user can create children of any of the classes. What I would like to do is something like the following: Foo MyFoo = new Foo(); Bar MyBar = new Bar(); MyFoo.Items = MyBar.Load(); MyBar.Save(MyFoo.Items); Obviously this won't work. Is there a clever way to do this that avoids creating intermediate lists? thanks, Andy

  • How to test that action uses argument?

    - by Caster Troy
    I am supposed to be using test-driven development but in this particular case, as I am having trouble, I implemented the action method first. It looks like this: public ViewResult Index(int pageNumber = 1) { var posts = repository.All(); var model = new PagedList<Post>(posts, pageNumber, PageSize); return View(model); } Both the repository and the PagedList<> have been tested already. Now I want to verify that when the action is given a page number that the page number is actually considered. private Mock<IPostsRepository> repository; private HomeController controller; [Test] public void Index_Doohickey() { var actual = controller.Index(2); // .. How do I test that the controller actually uses the page number here? }

  • Using jQuery, how do I way attach a string array as a http parameter to a http request?

    - by predhme
    I have a spring controller with a request mapping as follows @RequestMapping("/downloadSelected") public void downloadSelected(@RequestParam String[] ids) { // retrieve the file and write it to the http response outputstream } I have an html table of objects which for every row has a checkbox with the id of the object as the value. When they submit, I have a jQuery callback to serialize all ids. I want to stick those ids into an http request parameter called, "ids" so that I can grab them easily. I figured I could do the following var ids = $("#downloadall").serializeArray(); Then I would need to take each of the ids and add them to a request param called ids. But is there a "standard" way to do this? Like using jQuery?

  • C# - Why can't I enforce derived classes to have parameterless constructors?

    - by FrisbeeBen
    I am trying to do the following: public class foo<T> where T : bar, new { _t = new T(); private T _t; } public abstract class bar { public abstract void someMethod(); // Some implementation } public class baz : bar { public overide someMethod(){//Implementation} } And I am attempting to use it as follows: foo<baz> fooObject = new foo<baz>(); And I get an error explaining that 'T' must be a non-abstract type with a public parameterless constructor in order to use it as parameter 'T' in the generic type or method. I fully understand why this must be, and also understand that I could pass a pre-initialized object of type 'T' in as a constructor argument to avoid having to 'new' it, but is there any way around this? any way to enforce classes that derive from 'bar' to supply parameterless constructors?

  • NULL In a Class Destructor

    - by Hyper-DarkStar
    Simple question; Is it pointless to set a pointer( which allocates heap memory ) to NULL in the destructor? class SampleClass { public: SampleClass( int Init = 0 ) { Value = new int( Init ); } ~SampleClass( void ) { delete Value; Value = NULL; // Is this pointless? } int *Value; }; While on the subject of classes, when should I use the explicit keyword? Thanks.

  • Is there any way to pass an anonymous array as an argument in C++?

    - by Jeremy Friesner
    Hi all, I'd like to be able to declare an array as a function argument in C++, as shown in the example code below (which doesn't compile). Is there any way to do this (other than declaring the array separately beforehand)? #include <stdio.h> static void PrintArray(int arrayLen, const int * array) { for (int i=0; i<arrayLen; i++) printf("%i -> %i\n", i, array[i]); } int main(int, char **) { PrintArray(5, {5,6,7,8,9} ); // doesn't compile return 0; }

  • Prevent Java from parsing the command line parameters

    - by User1
    Would like to make anapplication in Java that will not automatically parse parameters used on the command-line. Currently, java requires public static void main(string[]) as the entry point signature. I would like just a single string that I parse myself. Can this be done at all? Here's an example: java MyProgram.class Hello World I would want it to give me Hello World without requiring quotes around that string. I would even settle for java giving me the entire java MyProgram.class Hello World. I'm thinking this is something beyond Java and has more to do with the shell.

  • @property, ok in this situation?

    - by fuzzygoat
    I am still finding my feet with objective-c and was wondering if its acceptable to use @property on the two objects below. #import <UIKit/UIKit.h> #import <MapKit/MapKit.h> @interface MapViewController : UIViewController <MKMapViewDelegate, CLLocationManagerDelegate> { CLLocationManager *locationManager; IBOutlet MKMapView *googleMapView; } @property(nonatomic, retain) CLLocationManager *locationManager; @property(nonatomic, retain) MKMapView *googleMapView; @end One of my reasons for using them is so that I can use the setters in my viewDidUnload, I seem to be using @property a lot and was just wondering if the use in this situation is acceptable? -(void)viewDidUnload { [self setLocationManager:nil]; [self setGoogleMapView:nil]; [super viewDidUnload]; } much appreciated Gary

  • How to measure how long is a function running?

    - by rhose87
    I want to see how long a function is running. So I added a timer object on my form and I came out with this code: private int counter = 0; //inside button click I have: timer = new Timer(); timer.Tick += new EventHandler(timer_Tick); timer.Start(); Result result = new Result(); result = new GeneticAlgorithms().TabuSearch(parametersTabu, functia); timer.Stop(); and: private void timer_Tick(object sender, EventArgs e) { counter++; btnTabuSearch.Text = counter.ToString(); } But this is not counting anything. Any ideas?

    - by case23
    I using the FileWatcher Class to locate changes on Files in a specific Folder. I managed to detect Changes on Files but not detailed Information. On the WatcherChangeTypes Enumeration Page http://msdn.microsoft.com/en-us/library/t6xf43e0%28v=VS.100%29.aspx they write the Change Type detects the changes include: changes to size, attributes, security settings, last write, and last access time. Is there a way to detect which kind of change happened? Thats the Event handler method i use. private void OnChanged(object source, FileSystemEventArgs e) { Console.WriteLine("File: " + e.FullPath + " Change Type: " + e.ChangeType); } Thank you in advance Case

  • Passing Services to MainViewModel - SHOULD I use a dependency injection container ?

    - by msfanboy
    Hello, I have this code: public partial class App : Application { protected override void OnStartup(StartupEventArgs e) { base.OnStartup(e); var mainVM = new MainViewModel ( new Service1(), ... new Service10(), ); var window = new MainWindow(); window.DataContext = mainVM; window.Show(); } } I pass all my Services instances to the MainViewModel. Within the MainViewModel I spread those services to other ViewModels via constructor parameter passing. Should I use any DI framework for the services in the App class? If yes whats the benefit of resolving the services instead of just creating the instance manually... ?

  • Swing invokeLater never shows up, invokeAndWait throws error. What can I do?

    - by Geo
    I have this code: try { SwingUtilities.invokeAndWait(new Runnable() { public void run() { try { dialog.handleDownload(); } catch (IOException io) { io.printStackTrace(); } } }); } catch(Exception io) { io.printStackTrace(); } in the handleDownload I'm reading an inputstream, calculating a progress bar's value, and setting it to that. So, when I click a button, a new JFrame opens up and does all the stuff I wrote above. If I have the dialog.handleDownload by itself ( in no SwingUtilities method ), it freezes until the operation is finished. If I add it in a invokeLater it's closed very fast ( I can't see anything, and the operation is not finished ). If I add it in a invokeAndWait I get the invokeAndWait cannot be called from the event dispatcher thread error. What should I do?

  • Odd Segue Behaviour - Not Firing

    - by Zak
    So I've noticed some very weird behaviour from my program. Here's a simplified code snippet and then I'll explain what occurs when built and ran. -(void)viewDidLoad { [super viewDidLoad]; ... if (self.sampleBool) { [self performSegueWithIdentifier:@"mySegue" sender:self]; } else { // do stuff } } ... -(IBAction)myMethod:(UITapGestureRecognizer*)sender { ... [self performSegueWithIdentifier:@"mySegue" sender:self]; } The segue triggers via the UITapGestureRecognizer fine - so I know the segue is linked correctly. However, when self.sampleBool is true and performSegueWithIdentifier is called within viewDidLoad, the segue does not fire. Anyone have any guesses? Any help or advice is appreciated. Thanks

  • UIRotationGestureRecognizer changes with CGAffineTransformMakeScale

    - by user523234
    A view is flipped using this: self.transform = CGAffineTransformMakeScale(-1, 1); // self is an UIView To rotate this view: -(void)handleRotate:(UIRotationGestureRecognizer *)recognizer { recognizer.view.transform = CGAffineTransformRotate(recognizer.view.transform, recognizer.rotation); recognizer.rotation = 0; } The issue is that after the view is flipped so is the rotation's direction. Any solution how to fix this? Edit: My current solution is using a boolean and negate the recognizer.rotation value in handleRotate method. But I am still looking for the technical solution.

  • UITableView: Need a liveUpdate (Huge amount of cells)

    - by antihero
    Hey all, I have a UITableView which shows some information. The informations are from a XMLFile. The Xmlfile is pretty big, about 500 entries. I don't want that the user has to wait until the parsing has finished, i want to add cell by cell to the TableView. Here's my code: -(void) onFinishedPartDownload:(id)item { if(odvTableViewDelegateController.odvs == nil) odvTableViewDelegateController.odvs = [NSMutableArray new]; if([odvTableViewDelegateController.odvs count]==0) { genericDelegate.tableView.delegate = odvTableViewDelegateController; genericDelegate.tableView.dataSource = odvTableViewDelegateController; } [odvTableViewDelegateController.odvs addObject:item]; [genericDelegate.tableView reloadData]; } This method is called everytime an item has parsed, but it reloads the tableView all at once at the end. I don't have my expected liveUpdate which i'm searching for. The intervall the method is called is about 0.001 to 0.0025 seconds. Any ideas to fix that? Sebastian
