  • C# to Java Conversion: What is a [DefaultProperty("value")]?

    - by Shiftbit
    I do not understand how the DefaultProperty Metadata tag work or what it signifies. I've read the MSDN and went through the sample but I find it confusing. DefaultPropertyAttribute Class I've read a few blogs and they seem to refer to the indexers. I'm not sure why you would want metadata for your properties? I am coming from a Java background, perhaps a Java analogy would help. [DefaultProperty("Value")] public abstract class FOO<T> : ANY, IBAR<T> { public FOO() { } public FOO(T value) { this.Value = value; } public virtual T Value { get; set; } }

  • Best way to globally set every control's ValidationGroup property in an asp.net?

    - by Steve Flook
    I have a User Control with form items that is re-used considerably throughout a large web application, and up until this point the validation summary upon an invalid form submission is being handled by the .aspx that consumes the User Control. Now I need to set the ValidationGroup property at runtime for each of my form items controls (textboxes, lists, validators, etc). Rather than do it manually by setting each control I'm interested in iterating through all the controls in the User Control, detecting if that control has a ValidationGroup property, and setting it's value that way. Something like this: For Each ctrl As System.Web.UI.Control In Me.Controls ' so now what is the proper way to detect if this control has the ValidationGroup property Next Code sample in vb.net or c# works for me. Many thanks!

  • Display fraction with numerator/denominator with empty fields for users to enter text

    - by Anil
    Hi all I have a scenario in which I need to design online keyboard with buttons implementing different mathematical functions in ASP.NET. For example 1) A button called "Fraction" Onclicking= should display A numerator and a denominator separated by '-' with empty fields. Just as we write fractions manually. Now when the user clicks on this button the cursor should focus on numerator displaying 'the division line' and then by pressing 'Down' arrow key(on computr keyboard) should focus on denominator allowing users to enter both fields. Keeping it simple the user should be able to toggle between numerator and denominator. Please help me with some sample code. I have got no idea. Thanks in advance

  • How to input test data using the DecisionTree module in python?

    - by lifera1n
    On the Python DescisionTree module homepage (DecisionTree-1.6.1), they give a piece of example code. Here it is: dt = DecisionTree( training_datafile = "training.dat", debug1 = 1 ) dt.get_training_data() dt.show_training_data() root_node = dt.construct_decision_tree_classifier() root_node.display_decision_tree(" ") test_sample = ['exercising=>never', 'smoking=>heavy', 'fatIntake=>heavy', 'videoAddiction=>heavy'] classification = dt.classify(root_node, test_sample) print "Classification: ", classification My question is: How can I specify sample data (test_sample here) from variables? On the project homepage, it says: "You classify new data by first constructing a new data vector:" I have searched around but have been unable to find out what a data vector is or the answer to my question. Any help would be appreciated!

  • @Resource annotated member not injected - bad code or bug?

    - by Brabster
    I am using an @Resource annotation in a class instantiated in a ServletContextListener's contextInitialized(...) method, but the member is always null. Here's my sample code. Listener: public void contextInitialized(ServletContextEvent sce) { System.err.println("In contextInitialised"); new ResourceListenerTargetTest().executeMe(); } ResourceListenerTargetTest: @Resource(name="MyJDBCResource") private DataSource source; public void executeMe() { /*try { InitialContext ictx = new InitialContext(); source = (DataSource)ictx.lookup("java:comp/env/MyJDBCResource"); } catch (NamingException e) { e.printStackTrace(); }*/ System.err.println("source is " + source); } If I switch the comments and run the manual resource lookup, it works fine. Should the @Resource annotation work like this, when used in a contextInitalized method? Appserver is WAS 7.0.0.5, if it should work then I guess it's a bug? Can anyone confirm?

  • How can I calculate the sum of all positive integers less than n? [closed]

    - by Adrian Godong
    I have the following function: f(n) = f(n - 1) + (n - 1) f(0) = 0 n >= 0 I have n declared on column A, and need the result of f(n) on column B. I'm trying to find the Excel formula equivalent for this function. Sample Result: A | B --+-- 0 | 0 or: A | B --+-- 1 | 0 or: A | B --+-- 4 | 6 but never: A | B --+-- 0 | 0 1 | 0 2 | 1 ... The biggest problem is, I can't simulate the value of f(n - 1). So referencing the previous row like the above example is invalid. I'm almost sure the answer is trivial, I just can't find it.

  • How do you delete a core data entry from the detail view?

    - by Sam
    I am working with an app similar to apple's core data recipes sample code. I want to be able to delete the entry from the detail view, much like apple's contacts app. The code below is deleting the 1st entry and not the selected entry. Not sure what I am doing wrong. NSIndexPath *indexPath = [myTableView indexPathForSelectedRow]; NSManagedObjectContext *context = [fetchedResultsController managedObjectContext]; [context deleteObject:[fetchedResultsController objectAtIndexPath:indexPath]]; [myTableView reloadData];

  • Is it possible to disable the iPhone's automatic hyperlinks?

    - by mririgo
    We send out a notification email whenever we have "phishing" emails reported to us. In these emails, we include a copy-paste of the text inside the original phishing email as a sample of what is reported to us. Our code strips all hyperlinks out of the email via PHP, but still includes (in plain text) the link. When users receive this email in their client (Thunderbird, Outlook, Horde/IMP, etc), the hyperlink is removed. However, the iPhone likes to take web addresses in plain text and automatically turn them into hyperlinks. Is there any possible way to stop this action from happening via a HTML tag or by using PHP to replace certain parts of the hyperlink?

  • What is the best way to detect Copy (Ctrl+C) event in an IWpfTextView?

    - by Nick U
    I am trying to detect a copy event in the text view and I have been researching the best way to do this. Is it to possibly hook into the StandardCommand Copy event somehow and detect it that way? Or is it possible to use the KeyProcessor(and simply detect Ctrl+C keypresses)? My extension is currently implementing the IWpfTextViewCreationListener; is there a way to somehow get access to the KeyProcessor or StandardCommand from the IWpfTextView that the listener is passing to me? If so, can you post a code sample that demonstrates this? Thanks, Nick

  • How to select the most recent set of dated records from a mysql table

    - by Ken
    I am storing the response to various rpc calls in a mysql table with the following fields: Table: rpc_responses timestamp (date) method (varchar) id (varchar) response (mediumtext) PRIMARY KEY(timestamp,method,id) What is the best method of selecting the most recent responses for all existing combinations of method and id? For each date there can only be one response for a given method/id. Not all call combinations are necessarily present for a given date. There are dozens of methods, thousands of ids and at least 356 different dates Sample data: timestamp method id response 2009-01-10 getThud 16 "....." 2009-01-10 getFoo 12 "....." 2009-01-10 getBar 12 "....." 2009-01-11 getFoo 12 "....." 2009-01-11 getBar 16 "....." Desired result: 2009-01-10 getThud 16 "....." 2009-01-10 getBar 12 "....." 2009-01-11 getFoo 12 "....." 2009-01-11 getBar 16 "....." (I don't think this is the same question - it won't give me the most recent response)

  • How to column-ify an output from a certain program?

    - by mbaitoff
    I have a program that generates and outputs a sequence of simple sample math homework tasks, like: 1 + 1 = ... 3 + 3 = ... 2 + 5 = ... 3 + 7 = ... 4 + 2 = ... a sequence can be quite long, and I'd like to save space when this sequence is printed by converting it as follows: 1 + 1 = ... 3 + 7 = ... 3 + 3 = ... 4 + 2 = ... 2 + 5 = ... that is, wrapping the lines into the two or more columns. I was expecting the column linux utility to do the job using the -c N option witn N=2, however, it still outputs the lines in one column whatever the N is. How would I do the column-ifying of the sequence of lines?

  • copy the item with the metadata that user just added to a folder called "NativeFiles". this folder i

    - by James
    I need to copy the item that user just added (for example. myresume.doc or financial.xls) with the metadata (doc lib obtains the columns from content type, ct obtains the columns from site colum) and copy the item with metadata in a folder called "NativeFile". Every doc library has this folder. I know itemadded can be used but then I heard itemadded fires before user have a chance to complete the metadata for the item they just added. What are my options? (new to sp, so some sample code would greatly help. or some good link similar to this issue) Sharepoint 2007, itemadded or itemadding or itemupdating or itemupdated....

  • debugfs_create_file doesn't create file

    - by bala1486
    Hello, I am trying to create a debugfs file using the debugfs_create_file(...). I have written a sample code for this. static int __init mmapexample_module_init(void) { file1 = debugfs_create_file("mmap_example", 0644, NULL, NULL, &my_fops)\ ; printk(KERN_ALERT "Hello, World\n"); if(file1==NULL) { printk(KERN_ALERT "Error occured\n"); } if(file1==-ENODEV) { printk(KERN_ALERT "ENODEV occured\n"); } return 0; } When i ran insmod i could get the Hello, World message but no the error message. So i think the debugfs_create_file worked fine. However i couldn't find any file in /sys/kernel/debug. The folder is there but it is empty. Can anyone help me with this? Thank you... Thanks, Bala

  • How can I make a core-plot graph on the phone that doesn't auto-expand to fill the whole superview

    - by Robb
    I'm pretty sure I saw an example where the graph wasn't filling the whole iPhone screen, but I can't get that to happen in my app, nor in the Core-Plot Test app from Switch On The Code. I've added a subview to the original CPLayerHostingView in the sample, then changed the classes – original back to UIView, new subview to CPLayerHostingView, and I've reconnected the File's owner's view outlet to the new subview. When I create a graph with: graph = [[CPXYGraph alloc] initWithFrame: theSubviewOutlet.bounds]; … and step through the first stages of building up the layers the bounds are accurate (i.e. the same as in the .xib) however, when all the initialization is done, and the graph shows up, it fills the whole superview. Am I missing something obvious?

  • iPhone simple commercial barcode reader via camera

    - by user347635
    Hey all, I've done some iPhone programming (safely midlevel) and now a requirement has come up for us to write a barcode reader that uses the iPhone camera. This is not for shopping or the general public but will be for internal use. My first thought was to simply programatically take a picture, upload it to server, and have a web service or something similar handle the heavy lifting of extracting the numbers out of the bar code. However I recently installed some apps already available on the iPhone that read bar codes, refer you to shopping sites, etc. and they seem to use the video camera to identify barcodes and extract the numbers. Does anyone know how this is being done or could point me to some open source or sample code?

  • Does the "using" directive provide any benefit?

Notice the difference between this sample: using Application.Data; namespace Application.Web { public class SampleClass { public void SampleMethod() { List<Category> categories = CreateCategoriesData(); Category expected = categories[0]; ... ... } } } And this one: namespace Application.Web { public class SampleClass { public void SampleMethod() { List<Data.Category> categories = CreateCategoriesData(); Data.Category expected = categories[0]; ... ... } } }

  • AcceptSecurityContext (Kerberos) returns SEC_E_LOGON_DENIED

    - by Davatuk
    Hi, I am trying to write a simple application that performs Kerberos authentication (no mutual authentication for now). The operating system is Windows server 2003, standard edition. I have setup Active directory and created an SPN using setspn tool. AcquireCredentialsHandle returns SEC_E_OK both on client and on server. InitializeSecurityContext on client side returns SEC_E_OK. AcceptSecurityContext on server side returns SEC_E_LOGON_DENIED. I am sure there's nothing wrong in my code since the same behaviour I see when using the sample application from the following MSDN article: http://msdn.microsoft.com/en-us/magazine/dvdarchive/bb985043.aspx So I guess there is something wrong in my setup. But I can't find out what. Maybe I have missed something in SPN setup? Any help is appreciated. Regards, David.

  • Implications of Fulltext Search over many columns

    - by Alex
    Hello, I have a really wide table which includes separate columns for billing address, shipping address, primary address, names, aliases etc. (I can't normalize this table further, and that's not the question here anyways). I'm implementing SQL Server fulltext search, and I'm wondering whether I should limit the search ability to just the primary fields (primary address and names for example), or if I can extend the search ability across all columns without occurring too much of a performance or memory penalty. I've done some basic testing with 10,000 sample rows and it's quite fast but I don't have much experience with fulltext indexing, especially its dictionary internals, so I don't know if the index is going to grow over time, or if there is anything else to consider. Thoughts?

  • Track Pedestrians

    - by 2vision2
    I am using OpenCV sample code “peopledetect.cpp” to detect and track pedestrians. The code uses HoG for feature extraction and SVM for classification. Please find the reference paper used here. The camera is mounted on the wall at a height of 10 feet and 45 degree down. There is no restriction on the pedestrian movement within the frame. I want to track the detected pedestrians’ movement within the frame. The issue I am facing is pedestrians are detected only in the middle region of the frame as most of the features are not visible as soon as the pedestrian enters the frame region. I want to track each person’s movement in the entire frame region. How to do it? Is tracking required? Can anyone give any reference to blogs/codes?

  • Storing API keys in Android, is obfustication enough?

    - by fredley
    I'm using the Dropbox API. In the sample app, it includes these lines: // Replace this with your consumer key and secret assigned by Dropbox. // Note that this is a really insecure way to do this, and you shouldn't // ship code which contains your key & secret in such an obvious way. // Obfuscation is good. final static private String CONSUMER_KEY = "PUT_YOUR_CONSUMER_KEY_HERE"; final static private String CONSUMER_SECRET = "PUT_YOUR_CONSUMER_SECRET_HERE"; I'm well aware of the mantra 'Secrecy is not Security', and obfuscation really only slightly increases the amount of effort required to extract the keys. I disagree with their statement 'Obfustication is good'. What should I do to protect the keys then? Is obfustication good enough, or should I consider something more elaborate?
