  • How to draw mixed-formatted text with .Net 2.0

    - by Baldewin
    Hi, is there a way to draw mixed-formatted text in .Net 2.0? I'm looking for something similar to System.Drawing.Graphics.DrawString() My problem with this method is that it allows only one format style for the whole text. But I need to draw text that has different format styles (e.g. a part of the text shall be underlined, another part bold and so on). Thanks a lot! Oliver

  • Difference between Resume and Goto in error handling block

    - by Rich Oliver
    I understand that in the following example a Resume statement should be used instead of a Goto statement. Sub Method() On Error Goto ErrorHandler ... CleanUp: ... Exit Function ErrorHandler: Log error etc Err.Clear 'Is this line actually necessary?' Resume CleanUp 'SHOULD USE THIS' Goto CleanUp 'SHOULD NOT USE THIS' End Sub My question is what difference is there in the execution of the two?

  • DataContractSerializer and XSLT

    - by Russ Clark
    I've got a simple Employee class that I'm trying to serialize to an XDocument and then use XSLT to transform the document to a page that displays both the properties (Name and ID) from the Employee class, and an html form with 2 radio buttons (Approve and Reject) and a submit button. Here is the Employee class: [Serializable, DataContract(Namespace="XSLT_MVC.Controllers/")] public class Employee { [DataMember] public string Name { get; set; } [DataMember] public int ID { get; set; } public Employee() { } public Employee(string name, int id) { Name = name; ID = id; } public XDocument GetDoc() { XDocument doc = new XDocument(); var serializer = new DataContractSerializer(typeof(Employee)); using (var writer = doc.CreateWriter()) { serializer.WriteObject(writer, this); writer.Close(); } return doc; } } And here is the XSLT file: <?xml version="1.0" encoding="utf-8"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" > <xsl:output method="html" indent="yes"/> <xsl:template match="/"> <html> <body> <xsl:value-of select="Employee/Name"/> <br /> <xsl:value-of select="Employee/ID"/> <br /> <form method="post" action="/Home/ProcessRequest?id={Employee/ID}"> <input id="Action" name="Action" type="radio" value="Approved"></input> Approved <br /> <input id="Action" name="Action" type="radio" value="Rejected"></input> Rejected <br /> <input type="submit" value="Submit"></input> </form> </body> </html> </xsl:template> </xsl:stylesheet> When I run this, all I get is the html form with the 2 radio buttons and the submit button, but not the properties from the Employee class. I saw a separate StackOverflow post that said I need to change the <xsl:template match="/"> to match on the namespace of my Employee class like this: <xsl:template match="/XSLT_MVC.Controllers">, but when I do that, now all I get are the Employee properties, and not the html form with the 2 radio buttons and the submit button. Does anyone know what needs to be done so that my transform will select and display both the Employee properties and the html form?

  • ASP.NET LINQ to SQL SubmitChanges() doesn't update the database

    - by Alex
    In my 2nd ASP.NET MVC project I'm facing a very weird problem: when I call the SubmitChanges method of the DataContext class, nothing updates in the database. It's weird because everything works fine with my first project. I'm using a remote database created in Sql Server Management Studio, I tried doing some queries there and in Visual Studio 2010 (where I have the connection to the database), they all work. Where might the problem be hidden?

  • Where about should my main class be created in a project?

    - by Dan
    The problem is where a class should be created in my code. An example is I have a UI class and a main logic class that controls other objects. Should the main logic class create the UI object, or should the UI object create the instance of the main logic class? An explanation of which method is best and why would be ideal. Thanks.

  • implementing java interface with scala class - type issue

    - by paintcan
    Why on earth won't this compile? Scala 2.8.0RC3: Java public interface X { void logClick(long ts, int cId, String s, double c); } Scala class Y extends X { def logClick(ts: Long, cId: Int,sid: java.lang.String,c: Double) : Unit = { ... } } Error class Y needs to be abstract, since method logClick in trait X of type (ts: Long,cId: Int,s: java.lang.String,c: Double)Unit is not defined

  • How to bridge git to ClearCase?

    - by Bas Bossink
    I've recently used git svn and enjoyed it very much. Now I'm starting a new project at a different customer. At that site the SCM of choice is ClearCase. I haven't found a baked equivalent of git svn for ClearCase. Is there anybody who has tried to use git locally as a front-end to ClearCase using some tricks, configuration or scripting with any measure of success? If so can you please explain the method used?

  • 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

  • Start a thread in a different process in Java

    - by kolm
    Hi there, is it possible to start a new thread in a different process in Java? I mean, I'm running a specific process and main thread, issuing ProcessBuilder for creating a new process. Before start() method is invoked, one must provide the command to be run in another process. Is it possible to start a new thread in newly created process? Thank you in advance for the reply. Best regards.

  • Java: Finding objects in collections.

    - by Jake
    This problem occurs over and over. I have some complicated object, such as a Cat, which has many properties, such as age, favorite cat food, and so forth. A bunch of Cats are stored in a Java Collection, and I need to find all the Cats that are aged 3, or those whose favorite cat food is Whiskas. Surely, I can write a custom method that finds those Cats with a specific property, but this gets cumbersome with many properties; is there some generic way of doing this?

  • Electroserver to Smartfox migration help

    - by Garrt
    I've got several demonstration programs that use Electroserver, but I'd also want to test the same code using Smartfox. What is the most straightforward method to do this kind of migration? I know the types of classes that need to be changed, but since the terminology is slightly different in both libraries, it's difficult to make a smooth transition. Fortunately, the programs are simple and I can probably do a bit of trial and error in replacing each missing class, but is there a better solution? Thanks.

  • Using Interface Builder tags

    - by pat
    I'm using interface builder's tag feature to access some UILabels I'm instantiating in a xib file. Since this a UITextViewCell I want to avoid superfluous method calls, but I want to do it right too. Thus when I do: UILabel *label = (UILabel *)[cell viewWithTag:1]; I'm wondering if I should wrap it up like so: if([[cell viewWithTag:1] isKindOfClass [UITableViewCell class]]) { UILabel *label = (UILabel *)[cell viewWithTag:1]; } Any discussion on this would be appreciated. Thanks

  • How do I change the title of the "back" button on a Navigation Bar

    - by Dale
    Currently the left bar button default value is the title of the view that loaded the current one, in other words the view to be shown when the button is pressed (back button). I want to change the text shown on the button to something else. I tried putting the following line of code in the view controller's viewDidLoad method but it doesn't seem to work. self.navigationItem.leftBarButtonItem.title = @"Log Out"; What should I do? Thanks.

  • Setting processor to 32-bit mode

    - by dboarman-FissureStudios
    It seems that the following is a common method given in many tutorials on switching a processor from 16-bit to 32-bit: mov eax, cr0 ; set bit 0 in CR0-go to pmode or eax, 1 mov cr0, eax Why wouldn't I simply do the following: or cr0, 1 Is there something I'm missing? Possibly the only thing I can think of is that I cannot perform an operation like this on the cr0 register.

  • Ruby on Rails: Can I do a "link_to" to call a create action?

    - by sjsc
    How would I correctly call the create action from a link_to? Here's the create action: def create recipe = Recipe.create(:name => "French fries") redirect_to recipe end For example, I thought something like this might work: <%= link_to "Create a default recipe", recipe_path, :method => :post %> I'm not sure if that's a recommended (or even correct) way to do it. Any idea?

  • Enable UIBarButtonItem if multiple UITextFields are all populated

    I have 3 UITextFields in a grouped UITableView and am trying to figure out the correct logic to only have my 'Save' UIBarButtonItem enabled when none of the UITextFields are empty. I'm currently using the - (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string UITextField delegate method to detect changes to the field character by character, but it is providing inconsistent results. Any ideas?
