  • Filling data in FormView from different tables

    - by wacky_coder
    Hi, I am using a FormView in an online quiz page for displaying the questions and RadioButtons (for answers) http://stackoverflow.com/questions/2438219/online-quiz-using-asp-dot-net Now, I need to pick the questions according to a TestID and a particular Set of that Test. The testid and the set_number would be passed using Session variables. I'm having 3 testIDs and 3 Sets per TestID and, thus, am using 9 tables to store the Questions, the Options and the correct answer. I need help on how to set the FormView so that it extracts the questions from a particular table only. Do I need to use a StoredProcedure ? If yes, how? PS: If I use only one table to store all the questions from each Set and for each TestID, I can do that, but I'd prefer using separate tables.

  • Efficient algorithm to find first available name

    - by Avrahamshuk
    I have an array containing names of items. I want to give the user the option to create items without specifying their name, so my program will have to supply a unique default name, like "Item 1". The challenge is that the name has to be unique so i have to check all the array for that default name, and if there is an item with the same name i have to change the name to be "Item 2" and so on until i find an available name. The obvious solution will be something like that: String name; for (int i = 0 , name = "Item " + i ; !isAvailable(name) ; i++); My problem with that algorithm is that it runs at O(N^2). I wonder if there is a known (or new) more efficient algorithm to solve this case. In other words my question is this: Is there any algorithm that finds the first greater-than-zero number that dose NOT exist in a given array, and runs at less that N^2? Thanks!

  • Load SWF data without loading sound, then load sound later

    - by Jon Sandness
    So, hypothetical situation here: I have an SWF that's 30MB. Sound files (music) make up 25MB, art and other things make up the remaining 5MB. Would it be possible for me to load the 5MB of necessary art and other things first to allow the user to operate the app, then after that's all loaded and they are operating the app, load the remaining 25MB of sound files in the background? UPDATE: Loading SWF externally is not an option.

  • PHP Doctrine: Custom nested set?

    - by ropstah
    Is it possible to have nested set capabilities in this somewhat custom setup? Consider these 4 tables: Object: (oid, name) contains: [1, 'Licence'] and [2, 'Exemption'] Licence: (lid, name) Exemption: (eid, name) Cost: (oid, oid_ref, cost_oid, cost_oid_ref) For: P = Licence with lid [1] R = Exemption with eid [2] i can say "object P is a parent to object R" if the following Cost record exists: [oid: 2 oid_ref: 2 cost_oid: 1 cost_oid_ref: 1] I understand that this creates somesort of 'conditional foreign key' relation which I need to define in code. Is it possible to have the nested set loaded with these conditions?

  • Problems in getting data from CFStreamCreatePairWithSocketToHost

    - by gkedmi
    Hi I'm building an iPhoe app with a socket to a PC app , I need to get an image from this PC app. It's my first time using "CFStreamCreatePairWithSocketToHost".After I establish the socket with "NSOperation" I call CFStreamClientContext streamContext = {0, self, NULL, NULL, NULL}; BOOL success = CFReadStreamSetClient(myReadStream, kMyNetworkEvents,MyStreamCallBack,&streamContext); CFReadStreamScheduleWithRunLoop(myReadStream, CFRunLoopGetCurrent(), kCFRunLoopDefaultMode); then I call CFWriteStreamWrite(myWriteStream, &writeBuffer, 3); // Open read stream. if (!CFReadStreamOpen(myReadStream)) { // Notify error } . . . while(!cancelled && !finished) { SInt32 result = CFRunLoopRunInMode(kCFRunLoopDefaultMode, 0.25, NO); if (result == kCFRunLoopRunStopped || result == kCFRunLoopRunFinished) { break; } if (([NSDate timeIntervalSinceReferenceDate] - _lastRead) MyConnectionTimeout) { // Call timed out cancelled = YES; break; } // Also handle stream status CFStreamStatus status = CFReadStreamGetStatus(myReadStream); } and then when I get "kCFStreamEventHasBytesAvailable" I use while (CFReadStreamHasBytesAvailable(myReadStream)) { CFReadStreamRead(myReadStream, readBuffer, 1000); //and buffer the the bytes } It's unpredictable , sometimes I get the whole picture , sometime I got just part of it , and I can't understand what make the different. can someone has an idea what is wrong here? thanks

  • How does a hash table work?

    - by Arec Barrwin
    I'm looking for an explanation of how a hashtable works - in plain English for a simpleton like me! For example I know it takes the key, calculates the hash (how?) and then performs some kind of modulo to work out where it lies in the array that the value is stored, but that's where my knowledge stops. Could anyone clarify the process. Edit: I'm not looking specifically about how hashcodes are calculated, but a general overview of how a hashtable works.

  • how to work with strings and integers as bit strings in python?

    - by Manuel
    Hello! I'm developing a Genetic Algorithm in python were chromosomes are composed of strings and integers. To apply the genetic operations, I want to convert these groups of integers and strings into bit strings. For example, if one chromosome is: ["Hello", 4, "anotherString"] I'd like it to become something like: 0100100100101001010011110011 (this is not actual translation). So... How can I do this? Chromosomes will contain the same amount of strings and integers, but this numbers can vary from one algorithm run to another. To be clear, what I want to obtain is the bit representation of each element in the chromosome concatenated. If you think this would not be the best way to apply genetic operators (such as mutation and simple crossover) just tell me! I'm open to new ideas. Thanks a lot! Manuel

  • Dynamic Typed Table/Model in J2EE?

    - by Viele
    Hi, Usually with J2EE when we create Model, we define the fields and types of fields through XML or annotation before compilation time. Is there a way to change those in runtime? or better, is it possible to create a new Model based on the user's input during the runtime? such that the number of columns and types of fields are dynamic (determined at runtime)? Help is much appreciated. Thank you.

  • Passing data to a non-static listBox, by calling function from another class

    - by Andrew A
    I have a simple forms program that I have been fighting with for a while now. I simply want to be able to call a method from a different class file (when a certain step is triggered in the code in that class file) in order to insert a string in the listBox. Here is my main method, pretty standard: class Program { [STAThread] static void Main(string[] args) { Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); Application.Run(new MainForm()); } } Here is the function which resides in my MainForm.cs file, which I can call just fine from that class file (via 'TextToBox(myString);'): public partial class MainForm : Form { ... // Function to output results to main Listbox window public void TextToBox(string aString) { // Place messages in Main Display list box window this.listBox1.Items.Insert(0, aString); } ... } But my problem is when I am in another class and I want to call 'TextToBox(myString);'. If I create another object reference of the MainForm, the code compiles fine but nothing will show up in the listBox. How do I do this? I cannot simply make TextToBox() static. I know I must create the object reference but I can't figure out how to reference the ORIGINAL MainForm, the one that was created in the Main method. Thanks in advance...

  • Sql Server Maintenance Plan Tasks & Completion

    - by Ben
    Hi All, I have a maintenance plan that looks like this... Client 1 Import Data (Success) -> Process Data (Success) -> Post Process (Completion) -> Next Client Client 2 Import Data (Success) -> Process Data (Success) -> Post Process (Completion) -> Next Client Client N ... Import Data and Process Data are calling jobs and Post Process is an Execute Sql task. If Import Data or Process Data Fail, it goes to the next client Import Data... Both Import Data and Process Data are jobs that contain SSIS packages that are using the built-in SQL logging provider. My expectation with the configuration as it stands is: Client 1 Import Data Runs: Failure - Client 2 Import Data | Success Process Data Process Data Runs: Failure - Client 2 Import Data | Success Post Process Post Process Runs: Completion - Success or Failure - Next Client Import Data This isn't what I'm seeing in my logs though... I see several Client Import Data SSIS log entries, then several Post Process log entries, then back to Client Import Data! Arg!! What am I doing wrong? I didn't think the "success" piece of Client 1 Import Data would kick off until it... well... succeeded aka finished! The logs seem to indicate otherwise though... I really need these tasks to be consecutive not concurrent. Is this possible? Thanks!

  • Neural Network: Handling unavailable inputs (missing or incomplete data)

    - by Mike
    Hopefully the last NN question you'll get from me this weekend, but here goes :) Is there a way to handle an input that you "don't always know"... so it doesn't affect the weightings somehow? Soo... if I ask someone if they are male or female and they would not like to answer, is there a way to disregard this input? Perhaps by placing it squarely in the centre? (assuming 1,0 inputs at 0.5?) Thanks

  • Avoid the collapsing effect on TreeView after updating data

    - by Manolete
    I have a TreeView used to display events. It works great, however every time new events are coming in and populating the tree collapse the tree again to the original position. That is very annoying when the refresh time is less than 1 second and it does not allow the user to interact with the items of the tree. Is there any way to avoid this behaviour? <TreeView Margin="1" BorderThickness="0" Name="eventsTree" ItemsSource="{Binding EventAlertContainers}" Background="#00000000" ScrollViewer.VerticalScrollBarVisibility="Auto" FontSize="14" VirtualizingStackPanel.IsVirtualizing="True"> <TreeView.Resources> <HierarchicalDataTemplate DataType="{x:Type C:EventAlertContainer}" ItemsSource="{Binding EventAlerts}"> <StackPanel Orientation="Horizontal"> <Image Width="20" Height="20" Margin="3,0" Source="Resources\Process_info_32.png" /> <TextBlock FontWeight="Bold" FontSize="16" Text="{Binding Description}" /> </StackPanel> </HierarchicalDataTemplate> <HierarchicalDataTemplate DataType="{x:Type C:EventAlert}" ItemsSource="{Binding Events}"> <StackPanel Orientation="Horizontal"> <Image Width="20" Height="20" Margin="0,0" Source="Resources\clock2_32.jpg" /> <TextBlock FontWeight="DemiBold" FontSize="14" Text="{Binding Name}" /> </StackPanel> </HierarchicalDataTemplate> <HierarchicalDataTemplate DataType="{x:Type C:Event}"> <StackPanel Orientation="Horizontal"> <Image Width="20" Height="20" Margin="0,0" Source="Resources\Task_32.png" /> <StackPanel Orientation="Vertical"> <TextBlock FontSize="12" Text="{Binding Name}" /> </StackPanel> </StackPanel> </HierarchicalDataTemplate> </TreeView.Resources> </TreeView>

  • exc_bad_access on insertNewObjectForEntityForName:inManagedObjectContext

    - by matthewc
    I have a garbage collected Cocoa application built on 10.5 frameworks. In an NSOperation In a loop I am quickly creating hundreds of NSManagedObjects. Frequently the creation of those NSManagedObejcts will crash with a exc_bad_access error. for (offsetCount; offsetCount < [parsedData count]; offsetCount++) { NSManagedObject *child = [NSEntityDescription insertNewObjectForEntityForName:@"Thread" inManagedObjectContext:[self moc]]; Thumbnail *thumb = [Thumbnail insertInManagedObjectContext:[self moc]]; Image *image = [Image insertInManagedObjectContext:[self moc]]; ... } Thumbnail and Image are both subclasses of NSManagedObject generated with mogenerator. insertInManagedObjectContext: looks like NSParameterAssert(moc_); return [NSEntityDescription insertNewObjectForEntityForName:@"Thumbnail" inManagedObjectContext:moc_]; NSParameterAssert(moc_); return [NSEntityDescription insertNewObjectForEntityForName:@"Image" inManagedObjectContext:moc_]; The NSManagedObjectContext returned by [self moc] is created for the NSOperation with NSPersistentStoreCoordinator *coord = [(MyApp_AppDelegate *)[[NSApplication sharedApplication] delegate] persistentStoreCoordinator]; self.moc = [[NSManagedObjectContext alloc] init]; [self.moc setPersistentStoreCoordinator:coord]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(contextDidSave:) name:NSManagedObjectContextDidSaveNotification object:self.moc]; [self.moc setMergePolicy:NSMergeByPropertyObjectTrumpMergePolicy]; [self.moc setUndoManager:nil]; [self.moc setRetainsRegisteredObjects:YES]; moc is defined as (nonatomic, retain) and synthesized.

  • Display additional data while iterating over a Django formset

    - by Jannis
    Hi, I have a list of soccer matches for which I'd like to display forms. The list comes from a remote source. matches = ["A vs. B", "C vs. D", "E vs, F"] matchFormset = formset_factory(MatchForm,extra=len(matches)) formset = MatchFormset() On the template side, I would like to display the formset with the according title (i.e. "A vs. B"). {% for form in formset.forms %} <fieldset> <legend>{{TITLE}}</legend> {{form.team1}} : {{form.team2}} </fieldset> {% endfor %} Now how do I get TITLE to contain the right title for the current form? Or asked in a different way: how do I iterate over matches with the same index as the iteration over formset.forms? Thanks for your input!

  • Strategy for Offline/Online data synchronization

    - by Adi
    My requirement is I have server J2EE web application and client J2EE web application. Sometimes client can go offline. When client comes online he should be able to synchronize changes to and fro. Also I should be able to control which rows/tables need to be synchronized based on some filters/rules. Is there any existing Java frameworks for doing it? If I need to implement on my own, what are the different strategies that you can suggest? One solution in my mind is maintaining sql logs and executing same statements at other side during synchronization. Do you see any problems with this strategy?

  • Microsoft Business Intelligence. Is what I am trying to do possible?

    - by Nai
    Hi guys, I have been charged with the task of analysing the log table of my company's website. This table contains a user's click path throughout the website for a given session. My company is looking to understand/spot trends based on the 'click paths' of our users. In doing so, identify groups of users that take on a certain 'click path' based on age/geography and so on. As you can tell from the title, I am completely new to BI and its capabilities so I was wondering: Are our objectives attainable? How should I go about doing this? I am currently reading books online as well as other e-books I have found. All signs seem to suggest this is possible via sequence clustering. Although the exact implementation and tweaks involved are currently lost on me. Therefore, if anyone has first hand experience in such an undertaking, I would be awesome if you could share it here. Cheers!

  • Where can I find an introduction to using PDO?

    I know my SQL safety isn't up to par. I've read on this site that PHP PDO would be a good first step, and while I did take a look at the PDO Manual it's a bit daunting. Is there somewhere I can find a tutorial on the basics of using PDO rather then straight MySQL calls?
