• How to change type of information for a Title column in SharePoint MOSS 2007 List?

  - by Ruba

  I created a calendar in SharePoint MOSS 2007 that is connected to my Outlook. I added a custom column “Person” to this list and the type of information in this column is: Person or Group. In SharePoint I can hide Title column and in Calendar View show this Person field as Month View Title. So I can see on the calendar who is working that day. Problem is in Outlook. It seems like Outlook doesn’t know a thing about custom fields. In Outlook I can see only Title and few other fields. I could rename Title field to Person, but I can’t change type of information that it contains. By default it is text field and no way to change it to Person or Group. If I could change those “default” column types, then I think my problem would be solved. I know it is possible. I created a custom list, but this list has also those “sticky” Title, Created By and Modified By columns that can’t be changed or removed. Maybe I have to create a custom list with some other program or code? Please help! Thanks in advance!

• My Core Animation block isn't working as I'd expect

  - by Alex Reynolds

  I have a UIView called activityView, which contains two subviews activityIndicator and cancelOperationsButton. These views are embedded in a XIB and wired up to my view controller. I have two methods that deal with activating (showing) and deactivating (hiding) these two subviews: - (void) enableActivityIndicator { [activityIndicator startAnimating]; [cancelOperationsButton setHidden:NO]; } - (void) disableActivityIndicator { [activityIndicator stopAnimating]; [cancelOperationsButton setHidden:YES]; } By themselves, these two methods work fine. To give this a bit of polish, I'd like to add an animation that fades these subviews in and out: - (void) enableActivityIndicator { [activityIndicator startAnimating]; [cancelOperationsButton setHidden:NO]; [UIView beginAnimations:@"fadeIn" context:nil]; [UIView setAnimationDelay:0.0f]; [UIView setAnimationDuration:1.0f]; [UIView setAnimationCurve:UIViewAnimationCurveEaseIn]; activityView.alpha = 1.0f; [UIView commitAnimations]; } - (void) disableActivityIndicator { [UIView beginAnimations:@"fadeOut" context:nil]; [UIView setAnimationDelay:0.0f]; [UIView setAnimationDuration:1.0f]; [UIView setAnimationCurve:UIViewAnimationCurveEaseOut]; activityView.alpha = 0.0f; [UIView commitAnimations]; [activityIndicator stopAnimating]; [cancelOperationsButton setHidden:YES]; } But the animations are not working — the subviews just show up or disappear without the parent view's alpha property having an effect on transparency. How should I write these methods to get the fade-in, fade-out effect I am after?

• rapid application developement tools for very basic GUI apps

  - by Jurij

  I know there are many RAD platforms out there. Infact there are so many that I'm having a hard time finding out which one fits me best. What I want is a RAD tool that would allow me to define a database data model (make DB tables) and then create (view and edit) forms for the various tables. Data input, updating and various queries should be easy and GUI should generate automatically. I'd like to add some additional functionality by coding (such as various complex calculations on the data). I'm a programmer so I'm willing to learn to use a more complete, full-blown RAD solution if you can point me to it (NetBeans and RubyOnRails being the two such frameworks that I'd would probably be high on the list). I'm currently doing Windows Forms logistics apps in .NET. I've actually developed a very crude and basic version of what I need, but I just know that there are solutions out there that are much better and I'd benefit by knowing how to use them. So in short, the basic requirements: * database based data storage (SQLite if possible) * very automated GUI creation * desktop based (as in: not a web app) * extendable by coding * used for creating simple data entry, view & query apps. So basically something like Oracle Forms or DotNetMushroom Rapid Application Developer. But for .NET and SQLite if possible.

• Two-way data binding of controls in a user control inside a FormView

  - by Sandor Drieënhuizen

  I'm trying to perform two-way data binding on the controls in my user control, which is hosted inside a FormView template. FormView: <asp:ObjectDataSource runat="server" ID="ObjectDataSource" TypeName="WebApplication1.Data" SelectMethod="GetItem" UpdateMethod="UpdateItem"> </asp:ObjectDataSource> <asp:FormView runat="server" ID="FormView"> <ItemTemplate> <uc:WebUserControl1 runat="server"></uc:WebUserControl1> </ItemTemplate> <EditItemTemplate> <uc:WebUserControl1 runat="server"></uc:WebUserControl1> </EditItemTemplate> </asp:FormView> User control: <%@ Control Language="C#" ... %> <asp:TextBox runat="server" ID="TitleTextBox" Text='<%# Bind("Title") %>'> </asp:TextBox> The binding works fine when the FormView is in View mode but when I switch to Edit mode, upon calling UpdateItem on the FormView, the bindings are lost. I know this because the FormView tries to call an update method on the ObjectDataSource that does not have an argument called 'Title'. I tried to solve this by implementing IBindableTemplate to load the controls that are inside my user control, directly into the templates (just like I had entered them declaratively like in the code above). However, when calling UpdateItem in edit mode, the container that gets passed into the ExtractValues method of the template, does not contain the TextBox anymore. It did in view mode! I have found some questions on SO that relate to this problem but they are rather dated and don't provide straight forward answers. How do you think I could solve this problem? It seems to be such a simple requirement but apparently it's more like opening a can of worms...

• Ruby page loading very very slowly - how should I speed it up?

  - by Elliot

  Hey guys, I'm going to try and describe the code in my view, without actually posting all the garbage: It has a standard shell (header, footer etc. in the layout) this is also where the sub navigation exists which is based on a loop (to find the amount of options) - on this page, we have 6 subnav links. Then in the index view, we have a 3rd level nav - with 3 links that use javascript to link/hide divs on the page. This means each of those original 6 options, all have their own 3'rd level nav, with each of their own 3 div pages. These three pages/divs have the input form for creating a record in rails, and then the other 2 pages show the records in different assortments. ALL of this code lives on one page (aside from the shell). The original sub nav uses a javascript tab solution, to browse through all of it... (this means its about 6 divs, which all contain 4 divs of function - so about 24 heavy divs). Loading it seems to take forever, although after loaded its extremely fast (obviously). My big question, is how should I attack this? I don't know ajax - although I imagine it'd be a good solution for loading the tabs when clicked. Thanks! Elliot

• Verifying existence of name and password in NSUserDefaults to Skip a login/Screen

  - by Michael Robinson

  I have a Tabbar/Tableview App that modally loads a Login/Signup view when the app loads, I have set up a Root.plist in a settings bundle for the name and password and have successfully retrieved the items. I want to be able to do two things: 1) Do a test to see if the NSUserDefault Strings are empty and if so load the Login/Signup view. 2) If the strings are available then use the string contents to login to my Webservice. Thanks in advance. Here is my LoginViewController .m : @synthesize usernameField; @synthesize passwordField; @synthesize loginButton; @synthesize loginIndicator; @synthesize usernameLabel; @synthesize passwordLabel; -(void)refreshFields { NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; usernameLabel.text = [defaults objectForKey:kUsernameKey]; passwordLabel.text = [defaults objectForKey:kPasswordKey]; } - (void)viewDidAppear:(BOOL)animated { [self refreshFields]; [super viewDidAppear:animated]; } - (void)viewDidLoad { [super viewDidLoad]; [self refreshFields]; [self.navigationController setNavigationBarHidden:YES animated:NO]; } - (IBAction) login: (id) sender { { NSString *post =[NSString stringWithFormat:@"username=%@&password=%@",usernameField.text, passwordField.text]; NSString *hostStr = @"http:~iphone_login.php?"; hostStr = [hostStr stringByAppendingString:post]; NSData *dataURL = [NSData dataWithContentsOfURL: [ NSURL URLWithString: hostStr ]]; NSString *serverOutput = [[NSString alloc] initWithData:dataURL encoding: NSASCIIStringEncoding]; NSLog(@"Site: %@",hostStr); NSLog(@"Site: %@",serverOutput); if([serverOutput isEqualToString:@"Yes"]){ UIAlertView *alertsuccess = [[UIAlertView alloc] initWithTitle:@"Congrats" message:@"You are authorized " delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil, nil]; [alertsuccess show]; [alertsuccess release];

• How to make a server.transfer() with a Response.AddHeader("refresh", "seconds") and not get a 404 er

  - by Unlimited071

  Hi all, so this is the scenario: I have a base class for all login-controlled pages: public class SessionControlledPage : Page { protected virtual void Page_Load(Object sender, EventArgs e) { Response.AddHeader("Refresh", Convert.ToString(Session.Timeout * 60 + 5)); if (Session.IsNewSession) { Response.Redirect("~/login.aspx"); } } } And a regularpage.aspx page that inherints from the base class: public partial class RegularPage : SessionControlledPage { override protected void Page_Load(Object sender, EventArgs e) { base.Page_Load(sender, e); Server.Transfer("~/otherpage.aspx"); } } Now let's say the original URL was http://localhost/regularpage.aspx and that Session.Timeout = 5. The problem appears when the refresh happens after the transfer takes place. I'm getting a 404 Not Found error and the URL changes for http://localhost/305. Notice that 5 * 60 + 5 = 305. Do you know why is this happening? got a solution? PD: I use transfer because I need to access some properties of regularpage.aspx on otherpage.aspx, maybe you could provide another solution for this too.

• Modifying UINavigation Bar Buttons in SubViews

  - by james

  I'm having trouble trying to modify the navigation bar in the subview portion of my application. self.navigationItem.rightBarButtonItem = [[[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(add_Clicked:)] autorelease]; I have no issues modifying the navigation bar in any of my UIViewControllers classes. The simplified application class outline is as such: AppDelegate - UIViewControllerA (has a left and a right navigationBarButton) - Subview is displayed when a SegmentControl is selected. (Within the subview, I'm trying to modify the right NavigationBarButton that is displayed) [self.view addSubview:newControllerName.view]; Methods I have attempted: Trying to set self.navigationItem.rightBarButtonItem within my subview to a new UIBarButtonItem. Creating a pointer to UIViewControllerA within my AppDelegate. The UIViewControllerA contains a function setNavButton I wrote to set the rightBarButtonItem to a button. Then I am referencing the AppDelegate's reference to UIViewControllerA and attempting to call setNavButton. I included a NSLog call to see if that function is being called and it is executing but the NavigationBar isn't being modified. I'm trying to avoid having to push a UIViewController after the SegmentControl is clicked in UIViewControllerA so that I can simulate the SegmentControl as tabs. I'm not getting any errors during compile or run time. Anyone have any ideas?

• Why can't I initialize a class through a setter?

  - by Rob emenaker

  If I have a custom class called Tires: #import <Foundation/Foundation.h> @interface Tires : NSObject { @private NSString *brand; int size; } @property (nonatomic,copy) NSString *brand; @property int size; - (id)init; - (void)dealloc; @end ============================================= #import "Tires.h" @implementation Tires @synthesize brand, size; - (id)init { if (self = [super init]) { [self setBrand:[[NSString alloc] initWithString:@""]]; [self setSize:0]; } return self; } - (void)dealloc { [super dealloc]; [brand release]; } @end And I synthesize a setter and getter in my View Controller: #import <UIKit/UIKit.h> #import "Tires.h" @interface testViewController : UIViewController { Tires *frontLeft, *frontRight, *backleft, *backRight; } @property (nonatomic,copy) Tires *frontLeft, *frontRight, *backleft, *backRight; @end ==================================== #import "testViewController.h" @implementation testViewController @synthesize frontLeft, frontRight, backleft, backRight; - (void)viewDidLoad { [super viewDidLoad]; [self setFrontLeft:[[Tires alloc] init]]; } - (void)dealloc { [super dealloc]; } @end It dies after [self setFrontLeft:[[Tires alloc] init]] comes back. It compiles just fine and when I run the debugger it actually gets all the way through the init method on Tires, but once it comes back it just dies and the view never appears. However if I change the viewDidLoad method to: - (void)viewDidLoad { [super viewDidLoad]; frontLeft = [[Tires alloc] init]; } It works just fine. I could just ditch the setter and access the frontLeft variable directly, but I was under the impression I should use setters and getters as much as possible and logically it seems like the setFrontLeft method should work. This brings up an additional question that my coworkers keep asking in these regards (we are all new to Objective-C); why use a setter and getter at all if you are in the same class as those setters and getters.

• Appending data to NSFetchedResultsController during find or create loop

  - by Justin Williams

  I have a table view that is managed by an NSFetchedResultsController. I am having an issue with a find-or-create operation, however. When the user hits the bottom of my table view, I am querying my server for another batch of content. If it doesn't exist in the local cache, we create it and store it. If it does exist, however, I want to append that data to the fetched results controller and display it. I can't quite figure that part out. Here's what I'm doing thus far: Passing the returned array of values from my server to an NSOperation to process. In the operation, create a new managed object context to work with. In the operation, I iterate through the array and execute a fetch request to see if the object exists (based on its server id). If the object doesn't exist, we create it and insert it into the operations' managed object context. After the iteration completes, we save the managed object context, which triggers a merge notification on my main thread. At this point, any objects that weren't locally cached in my Core Data store before will appear, but the ones that previously existed do not come along for the ride. I feel like it's something simple I'm missing, and could use a nudge in the right direction.

• Printing an invisible NSView

  - by Rodger Wilson

  Initially I created a simple program with a custom NSView. I drew a picture (certificate) and printed it! beautiful! Everything worked great! I them moved my custom NSView to an existing application. My hope was that when a user hit print it would print this certificate. Simple enough. I figured a could have a NSView pointer in my controller code. Then at initialization I would populate the pointer. Then when someone wanted to print the certificate it would print. The problem is that all of my drawing code is in the "drawRect" method. This method doesn't get called because this view is never displayed in a window. I have heart that others use non-visible NSView objects just for printing. What do I need to do. I really don't want to show this view to the screen. Rodger

• linq to sql dynamic data modify object before insert and update

  - by Dan Tanner

  I'm using Dynamic Data and LINQ to SQL for some admin pages on a .NET 3.5 web app. All my admin tables a CreatedBy, CreatedDate, UpdatedBy, and UpdatedDate. I'm looking for a way to inject the setting of these properties before the objects are inserted and updated. I've seen an object_inserting hook if you have a linq to sql datasource in the web form, but I'm using dynamic data...is there an easy way to generically set that? And I've also looked at modifying each of the partial classes for my admin objects, but the closest hook I see is to implement the OnValidate method with the Insert action. Any suggestions? TIA.

• seeing C# windows forms project code from F#

  - by Pessimist

  I have a C# Windows Forms project open with some C# code in it. Question: How can I have an F# file that I can write F# code in but still referencing all the C# code I have on Form1.cs (including the GUI). I can successfully do this: - Create a C# Windows Forms project - Create a F# Library project - Reference the F# Library DLL from my C# project - That way I can call F# functions from C# But I still can't see my buttons and textboxes from F# I understand that that is because it's a library and it can't reference System.Windows.Forms So how do I fix this? I don't want it to be a library or this or that, I just want it to be a file that will allow me to write F# code while being able to reference my C# Form and code. I guess you can say I want an F# file that is also a "partial class Form1" so that I can continue writing code for the same Project, but using F# instead. How do I do that?

• Castle Windsor Dynamic Property in XML config

  - by haxelit

  I'm trying to set the DataContext on ApplicationMainWindow which is a WPF window. When I set it up in the XML like so it leaves the DataContext null: <!-- View Models --> <component id="mainwindow.viewmodel" type="ProjectTracking.ApplicationMainViewModel, ProjectTracking" inspectionBehavior="none" lifestyle="transient"> </component> <!-- UI Components --> <component id="mainwindow.view" type="ProjectTracking.ApplicationMainWindow, ProjectTracking" inspectionBehavior="none" lifestyle="transient"> <parameters> <DataContext>${mainwindow.viewmodel}</DataContext> </parameters> </component> But if I do it this way via C# it works. _Kernel.Register( ... Component.For<ApplicationMainWindow>() .DynamicParameters( (k,d) => { d["DataContext"] = k[typeof(ApplicationMainViewModel)]; }) ); I'm instantiating my window like so: Window window = _Kernel[typeof(ApplicationMainWindow)] as Window; When I configure windsor via the xml config it leaves my DataContext NULL, but when I configure it via code it works like a charm. Do I need to use code to pull this off, or should it work via XML config ? Thanks, Raul

• Programatic re-evalutation of MVVM command's "can execute" state

  - by dzs

  Hello! I'm writing a WPF application using the MVVM pattern, based on the following article: WPF Apps With The Model-View-ViewModel Design Pattern I have two buttons on my View with the buttons' "Command" property bound (with data binding) to a given instance of the RelayCommand class (see "Figure 3 The RelayCommand Class" from the article above). The RelayCommand class has support for checking whether the given command can be executed. WPF automatically disables buttons whose command cannot be executed. Each of my commands (in the ViewModel class) start a background operation, and the command cannot be executed again until the background operation is finished. The RelayCommand instances have information whether the background operation is still working or it is finished. My problem is the following: after pressing the any of the buttons, the buttons automaticaly go disabled (which is OK) because the background operation started and the command cannot be executed until it is finished, but after the operation had finished, the buttons don't go enabled automatically because their command's "can be executed" predicate is not automatically reevaluated. The reevaluation can be manually triggered by having the application loose and regain focus (by pressing ALT+TAB). After doing this trick, the buttons get enabled once again. How can I programatically reevaluate the buttons' command's "can execute" state?

• Grouped UITableView Footer Sometimes Hidden On Quick Scroll

  - by jdandrea

  OK, this one is a puzzler. There is one similar post but it's not similar enough to count, so I'm posting this one. :) I've got a grouped UITableView with a header and footer. The footer includes two UIButton views, side-by-side. Nothing major. Now … there is a toggle button in a UIToolbar at the bottom for more/less info in this table view. So I build my index paths to delete/insert with fade row animation, all the usual ingredients, sandwiched between beginUpdates and endUpdates calls on the UITableView … and this works fine! In also happens that my footer can sometimes be pushed off past the bottom of the display. Here's where it gets weird. If I drag my finger up the display, scrolling the view upward, I should see that footer eventually, right? Well … most of the time I do. BUT, if I flick my finger up, for a faster scroll, the footer is missing. Even if you try to tap in that area - no response. However, if I scroll back down again, just to hide that footer (or rather hide the area where the footer would normally be), and then scroll back up, it's there once again! This only happens when inserting rows. If I delete rows, the footer stays put … unless of course it was already hidden and I didn't perform the aforementioned incantation to get it back. :) I am trying to trace through this, but to no avail. I suppose tracing through scroll operations is a bit of a crazy proposition! Perhaps some creative logging … suggestions, anyone? Or is this a known issue in 3.1 where row insert/deletes are concerned? (I don't recall seeing it until 3.1.)

• WPF, getting two way binding to work on custom control

  - by e28Makaveli

  Two way binding does not work on my custom control with the following internals: public partial class ColorInputControl { public ColorInputControl() { InitializeComponent(); colorPicker.AddHandler(ColorPicker.SelectedColorChangedEvent, new RoutedPropertyChangedEventHandler( SelectedColorChanged));; colorPicker.AddHandler(ColorPicker.CancelEvent, new RoutedPropertyChangedEventHandler(OnCancel)); } public static readonly DependencyProperty SelectedColorProperty = DependencyProperty.Register ("SelectedColor", typeof(Color), typeof(ColorInputControl), new PropertyMetadata(Colors.Transparent, null)); public Color SelectedColor { get { return (Color)GetValue(SelectedColorProperty); //return colorPicker.SelectedColor; } set { SetValue(SelectedColorProperty, value); colorPicker.SelectedColor = value; } } private void SelectedColorChanged(object sender, RoutedPropertyChangedEventArgs<Color> e) { SetValue(SelectedColorProperty, colorPicker.SelectedColor); } } SelectedColor is being bound to a property that fires INotifyPropertyChanged event control when it changes. However, I cannot get two way binding to work. Changes from the UI are pesisted to the data source. However, changes originating from the data source are not reflected on the UI. What did I miss? TIA.

• CGContext problems

  - by Peyman

  Hi I have a CALayer tree hierarchy A B C D where A is the view's root layer (and I create and add B,C and D layers. I am using the same delegate method `- (void) drawLayer:(CALayer *) theLayer inContext:(CGContextRef)context to provide content to each of these layers (implemented through a switch statement in the above method). At initiation A's content is drawn (A.contents) sequentially through these methods `- (void) drawLayer:(CALayer *) theLayer inContext:(CGContextRef)context -(void) drawCircle:(CALayer *) theLayer inContext:(CGContextRef)context where drawCircle does CGContextSaveGState(context); / draws circle and other paths here / CGContextRestoreGState(context); CGImageRef contentImage = CGBitmapContextCreateImage(context); theLayer.contents = (id) contentImage; CGImageRelease(contentImage); (i.e I save the Context, do the drawing, restore the context, make a bitmap of the context, update the layer's contents, in this case A's, then release the contentimage). When the user then clicks somewhere in the circle at touchesEnded:(NSSet*)touches withEvent:(UIEvent*)event delegate method I then try to paint the content of B by (still in touchesEnded:) CGContextRef context = UIGraphicsGetCurrentContext(); [self drawLayer:self.B inContext:context]; [self.B setNeedsDisplay]; the setNeedsDisplay call the delegate - drawLayer:(CALayer *) theLayer inContext:(CGContextRef)context again but this time the switch statement (using a layer flag) calls [self drawCircle:theLayer inContext:context]; with color red. The problem I am facing is that when -drawCircle: inContext: is called I get a long list of CGContext errors, starting with <Error>: CGContextSaveGState: invalid context and ending with CGBitmapContextCreateImage: invalid context I played around with making context the view's ivar and it worked so i am sure the context is the problem but I don't know what. I've tried CGContextFlush but it didn't help. Any help would be appreciated thank you

• Ubuntu One Folder Sync Filter

  - by Andy Barlow

  Hi, I am trying to modify the Ubuntu One File syncing python scripts to not including things like .iso's. I have got as far as finding this file: /usr/share/pyshared/ubuntuone/u1sync/constants.py Inside is this piece of code: import re # the name of the directory u1sync uses to keep metadata about a mirror METADATA_DIR_NAME = u".ubuntuone-sync" # filenames to ignore SPECIAL_FILE_RE = re.compile(".*\\.(" "(u1)?partial|part|" "(u1)?conflict(\\.[0-9]+)?)$") How can I edit this last section (regex?) and make it ignore .iso files??? I'm fairly sure this is the place to put it! Pretty sure this is standard python action :) Any help would be appreciated. Thanks kindly. Andy
