• How to pushviewcontroller to a viewcontroller stored in a tabbaritem?

  - by Jann

  First of all I know this is a long question. REST ASSURED I have tried to figure it out on my own (see: StackOverflow #2609318). This is driving me BATTY! After trying and failing to implement my own EDIT feature in the standard moreNavigationController, I have decided to re-implement my own MORE feature. I did the following: Add a HOME view controller which I init with: initWithRootViewController Add 3 other default tabs with: ResortsListViewController *resortsListViewController; resortsListViewController = [[ResortsListViewController alloc] initWithNibName:@"ResortsListView" bundle:nil]; resortsListViewController.title = [categoriesDictionary objectForKey:@"category_name"]; resortsListViewController.tabBarItem.image = [UIImage imageNamed:@"whatever.png"]; resortsListViewController.navigationItem.title=@"whatever title"; localNavigationController = [[UINavigationController alloc] initWithRootViewController:resortsListViewController]; localNavigationController.navigationBar.barStyle = UIBarStyleBlack; [localControllersArray addObject:localNavigationController]; [localNavigationController release]; [resortsListViewController release]; Those work when i add them to the tabbar. (ie: click on them and it goes to the view controller) Then I add my own MORE view controller to the tabbar: MoreViewController *moreViewController; moreViewController = [[MoreViewController alloc] initWithNibName:@"MoreView" bundle:nil]; moreViewController.title = @"More"; moreViewController.tabBarItem.image = [UIImage imageNamed:@"more.png"]; moreViewController.navigationItem.title=@"More Categories"; localNavigationController = [[UINavigationController alloc] initWithRootViewController:moreViewController]; localNavigationController.navigationBar.barStyle = UIBarStyleBlack; [localControllersArray addObject:localNavigationController]; [localNavigationController release]; [moreViewController release]; Then tabBarController.viewControllers = localControllersArray; tabBarController.moreNavigationController.navigationBar.barStyle = UIBarStyleBlack; tabBarController.customizableViewControllers = [NSArray arrayWithObjects:nil]; tabBarController.delegate = self; That creates the necessary linkages. Okay, so far all is well. I get a HOME tab, 3 category tabs and a customized MORE tab -- which all work. in the MORE tab view controller I implement a simple table view that displays all the other tabs I have in rows. SINCE I want to be able to switch them in and out of the tabbar I created them JUST like i did the resortslistviewcontroller above (ie: as view controllers in an array). When I pull them out to display the title in the tableview (so the user can go to that "view") i simply do the following: // [myGizmoClass CategoryArray] holds the array of view controller tab bar items that are NOT shown on the main screen. - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { ... etc... UIViewController *Uivc = [[myGizmoClass plusCategoryArray] objectAtIndex:indexPath.row]; cell.textLabel.text = [Uivc title]; cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator; } THIS is where it falls through: - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { MyGizmoClass *myGizmoClass= [MyGizmoClass sharedManager]; UIViewController *tbi = [[myGizmoClass plusCategoryArray] objectAtIndex:indexPath.row]; NSLog(@"%@\n",[[tbi navigationItem ]title]); [self.navigationController pushViewController:tbi animated:YES]; } This is the error i get ("ATMs" is the title for the clicked tableview cell so i know the Uivc title is pulling the correct title and therefore the correct "objectatindex": 2010-04-09 11:25:48.222 MouseAddict[47485:207] ATMs 2010-04-09 11:25:48.222 MouseAddict[47485:207] * Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Pushing a navigation controller is not supported' BIG QUESTION: How do i make the associated VIEW of the UIViewController *tbi show and get pushed into view? I am GUESSING that the UIViewController is the correct class for this tbl .. i am not sure. BUT i just wanna get the view so i can push it onto the stack. Can someone plz help?

• Animate button on MouseOver and MouseDown

  - by haagel

  I'm making my own ControlTemplate for a standard Button in WPF. I want to change the background of my button when the user hovers over the button with the mouse, but also when the user presses the button (to yet another color). This seems like a common behavior, but I can't get it to work. My template consists of a Border with an Image inside. It is the background color (a gradient really) of the Border that I want to animate. I have triggers in my template that activates animations (storyboards). The MouseOver/Out works just fine. My problem occurs when I press the button. The Press animation runs as it should, and so does the Release animation. But after this the MouseOut will never run. The button gets stuck in the MouseOver state. What am I doing wrong? <ControlTemplate TargetType="{x:Type Button}"> <ControlTemplate.Resources> <Storyboard x:Key="MouseOverAnimation"> <ColorAnimation Storyboard.TargetName="ButtonBorderGradientStop1" Storyboard.TargetProperty="Color" To="#ffefefff" Duration="0:0:0.2" /> <ColorAnimation Storyboard.TargetName="ButtonBorderGradientStop2" Storyboard.TargetProperty="Color" To="#ffc7c7ff" Duration="0:0:0.2" /> </Storyboard> <Storyboard x:Key="MouseOutAnimation"> <ColorAnimation Storyboard.TargetName="ButtonBorderGradientStop1" Storyboard.TargetProperty="Color" To="#ffeeeeee" Duration="0:0:0.2" /> <ColorAnimation Storyboard.TargetName="ButtonBorderGradientStop2" Storyboard.TargetProperty="Color" To="#ffcccccc" Duration="0:0:0.2" /> </Storyboard> <Storyboard x:Key="MouseDownAnimation"> <ColorAnimation Storyboard.TargetName="ButtonBorderGradientStop1" Storyboard.TargetProperty="Color" To="#ffc7c7ff" Duration="0:0:0.1" /> <ColorAnimation Storyboard.TargetName="ButtonBorderGradientStop2" Storyboard.TargetProperty="Color" To="#ff9a9aff" Duration="0:0:0.1" /> </Storyboard> <Storyboard x:Key="MouseUpAnimation"> <ColorAnimation Storyboard.TargetName="ButtonBorderGradientStop1" Storyboard.TargetProperty="Color" To="#ffefefff" Duration="0:0:0.1" /> <ColorAnimation Storyboard.TargetName="ButtonBorderGradientStop2" Storyboard.TargetProperty="Color" To="#ffc7c7ff" Duration="0:0:0.1" /> </Storyboard> </ControlTemplate.Resources> <Border x:Name="ButtonBorder" CornerRadius="0" BorderBrush="#55aaaaaa" BorderThickness="1" Width="23" Height="22"> <Border.Background> <LinearGradientBrush StartPoint="0,0" EndPoint="0,1"> <GradientBrush.GradientStops> <GradientStop x:Name="ButtonBorderGradientStop1" Color="#ffeeeeee" Offset="0.0" /> <GradientStop x:Name="ButtonBorderGradientStop2" Color="#ffcccccc" Offset="1.0" /> </GradientBrush.GradientStops> </LinearGradientBrush> </Border.Background> <Image x:Name="ButtonIcon" Source="icons/searchicon_bw.png" Width="16" Height="16" /> </Border> <ControlTemplate.Triggers> <Trigger Property="IsMouseOver" Value="True"> <Trigger.EnterActions> <BeginStoryboard Storyboard="{StaticResource MouseOverAnimation}" /> </Trigger.EnterActions> <Trigger.ExitActions> <BeginStoryboard Storyboard="{StaticResource MouseOutAnimation}" /> </Trigger.ExitActions> </Trigger> <Trigger Property="IsPressed" Value="True"> <Trigger.EnterActions> <BeginStoryboard Storyboard="{StaticResource MouseDownAnimation}" /> </Trigger.EnterActions> <Trigger.ExitActions> <BeginStoryboard Storyboard="{StaticResource MouseUpAnimation}" /> </Trigger.ExitActions> </Trigger> </ControlTemplate.Triggers> </ControlTemplate>

• Passing integer lists in a sql query, best practices

  - by Artiom Chilaru

  I'm currently looking at ways to pass lists of integers in a SQL query, and try to decide which of them is best in which situation, what are the benefots of each, and what are the pitfalls, what should be avoided :) Right now I know of 3 ways that we currently use in our application. 1) Table valued parameter: Create a new Table Valued Parameter in sql server: CREATE TYPE [dbo].[TVP_INT] AS TABLE( [ID] [int] NOT NULL ) Then run the query against it: using (var conn = new SqlConnection(DataContext.GetDefaultConnectionString)) { var comm = conn.CreateCommand(); comm.CommandType = CommandType.Text; comm.CommandText = @" UPDATE DA SET [tsLastImportAttempt] = CURRENT_TIMESTAMP FROM [Account] DA JOIN @values IDs ON DA.ID = IDs.ID"; comm.Parameters.Add(new SqlParameter("values", downloadResults.Select(d => d.ID).ToDataTable()) { TypeName = "TVP_INT" }); conn.Open(); comm.ExecuteScalar(); } The major disadvantages of this method is the fact that Linq doesn't support table valued params (if you create an SP with a TVP param, linq won't be able to run it) :( 2) Convert the list to Binary and use it in Linq! This is a bit better.. Create an SP, and you can run it within linq :) To do this, the SP will have an IMAGE parameter, and we'll be using a user defined function (udf) to convert this to a table.. We currently have implementations of this function written in C++ and in assembly, both have pretty much the same performance :) Basically, each integer is represented by 4 bytes, and passed to the SP. In .NET we have an extension method that convers an IEnumerable to a byte array The extension method: public static Byte[] ToBinary(this IEnumerable intList) { return ToBinaryEnum(intList).ToArray(); } private static IEnumerable<Byte> ToBinaryEnum(IEnumerable<Int32> intList) { IEnumerator<Int32> marker = intList.GetEnumerator(); while (marker.MoveNext()) { Byte[] result = BitConverter.GetBytes(marker.Current); Array.Reverse(result); foreach (byte b in result) yield return b; } } The SP: CREATE PROCEDURE [Accounts-UpdateImportAttempts] @values IMAGE AS BEGIN UPDATE DA SET [tsLastImportAttempt] = CURRENT_TIMESTAMP FROM [Account] DA JOIN dbo.udfIntegerArray(@values, 4) IDs ON DA.ID = IDs.Value4 END And we can use it by running the SP directly, or in any linq query we need using (var db = new DataContext()) { db.Accounts_UpdateImportAttempts(downloadResults.Select(d => d.ID).ToBinary()); // or var accounts = db.Accounts .Where(a => db.udfIntegerArray(downloadResults.Select(d => d.ID).ToBinary(), 4) .Select(i => i.Value4) .Contains(a.ID)); } This method has the benefit of using compiled queries in linq (which will have the same sql definition, and query plan, so will also be cached), and can be used in SPs as well. Both these methods are theoretically unlimited, so you can pass millions of ints at a time :) 3) The simple linq .Contains() It's a more simple approach, and is perfect in simple scenarios. But is of course limited by this. using (var db = new DataContext()) { var accounts = db.Accounts .Where(a => downloadResults.Select(d => d.ID).Contains(a.ID)); } The biggest drawback of this method is that each integer in the downloadResults variable will be passed as a separate int.. In this case, the query is limited by sql (max allowed parameters in a sql query, which is a couple of thousand, if I remember right). So I'd like to ask.. What do you think is the best of these, and what other methods and approaches have I missed?

• How do I use UIImagePickerController just to display the camera and not take a picture?

  - by Thomas

  Hello All: I'd like to know how to open the camera inside of a pre-defined frame (not the entire screen). When the view loads, I have a box, and inside it, I want to display what the camera sees. I don't want to snap a picture, just basically use the camera as a viewfinder. I have searched this site and have not yet found what I'm looking for. Please help. Thanks! Thomas Update 1: Here is what I have tried so far. 1.) I added UIImageView to my xib. 2.) Connect the following outlet to the UIImageView in IB IBOutlet UIImageView *cameraWindow; 3.) I put the following code in viewWillAppear -(void)viewWillAppear:(BOOL)animated { [super viewWillAppear:animated]; UIImagePickerController *picker = [[UIImagePickerController alloc] init]; picker.delegate = self; picker.sourceType = UIImagePickerControllerSourceTypeCamera; [self presentModalViewController:picker animated:YES]; NSLog(@"viewWillAppear ran"); } But this method does not run, as evident by the absence of NSLog statement from my console. Please help! Thanks, Thomas Update 2: OK I got it to run by putting the code in viewDidLoad but my camera still doesn't show up...any suggestions? Anyone....? I've been reading the UIImagePickerController class reference, but am kinda unsure how to make sense of it. I'm still learning iPhone, so it's a bit of a struggle. Please help! - (void)viewDidLoad { [super viewDidLoad]; // Create a bool variable "camera" and call isSourceTypeAvailable to see if camera exists on device BOOL camera = [UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]; // If there is a camera, then display the world throught the viewfinder if(camera) { UIImagePickerController *picker = [[UIImagePickerController alloc] init]; // Since I'm not actually taking a picture, is a delegate function necessary? picker.delegate = self; picker.sourceType = UIImagePickerControllerSourceTypeCamera; [self presentModalViewController:picker animated:YES]; NSLog(@"Camera is available"); } // Otherwise, do nothing. else NSLog(@"No camera available"); } Thanks! Thomas Update 3: A-HA! Found this on the Apple Class Reference. Discussion The delegate receives notifications when the user picks an image or movie, or exits the picker interface. The delegate also decides when to dismiss the picker interface, so you must provide a delegate to use a picker. If this property is nil, the picker is dismissed immediately if you try to show it. Gonna play around with the delegate now. Then I'm going to read on wtf a delegate is. Backwards? Whatever :-p Update 4: The two delegate functions for the class are – imagePickerController:didFinishPickingMediaWithInfo: – imagePickerControllerDidCancel: and since I don't actually want to pick an image or give the user the option to cancel, I am just defining the methods. They should never run though....I think.

• Why are these divs not aligned and space between?

  Why isnt everything aligned? No yellow should be visible and no orange should be visible except for the right side and bottom left where theres space for another image. Basically my images are pretty much aligned to the center (i have other pics not in this example which is easier to see). However in this case when i have 150px height image the 150 width seems start lower.

• Block filters using fragment shaders

  - by Nils

  I was following this tutorial using Apple's OpenGL Shader Builder (tool similar to Nvidia's fx composer, but simpler). I could easily apply the filters, but I don't understand if they worked correct (and if so how can I improve the output). For example the blur filter: OpenGL itself does some image processing on the textures, so if they are displayed in a higher resolution than the original image, they are blurred already by OpenGL. Second the blurred part is brighter then the part not processed, I think this does not make sense, since it just takes pixels from the direct neighborhood. This is defined by float step_w = (1.0/width); Which I don't quite understand: The pixels are indexed using floating point values?? Edit: I forgot to attach the exact code I used: Fragment Shader // Originally taken from: http://www.ozone3d.net/tutorials/image_filtering_p2.php#part_2 #define KERNEL_SIZE 9 float kernel[KERNEL_SIZE]; uniform sampler2D colorMap; uniform float width; uniform float height; float step_w = (1.0/width); float step_h = (1.0/height); // float step_w = 20.0; // float step_h = 20.0; vec2 offset[KERNEL_SIZE]; void main(void) { int i = 0; vec4 sum = vec4(0.0); offset[0] = vec2(-step_w, -step_h); // south west offset[1] = vec2(0.0, -step_h); // south offset[2] = vec2(step_w, -step_h); // south east offset[3] = vec2(-step_w, 0.0); // west offset[4] = vec2(0.0, 0.0); // center offset[5] = vec2(step_w, 0.0); // east offset[6] = vec2(-step_w, step_h); // north west offset[7] = vec2(0.0, step_h); // north offset[8] = vec2(step_w, step_h); // north east // Gaussian kernel // 1 2 1 // 2 4 2 // 1 2 1 kernel[0] = 1.0; kernel[1] = 2.0; kernel[2] = 1.0; kernel[3] = 2.0; kernel[4] = 4.0; kernel[5] = 2.0; kernel[6] = 1.0; kernel[7] = 2.0; kernel[8] = 1.0; // TODO make grayscale first // Laplacian Filter // 0 1 0 // 1 -4 1 // 0 1 0 /* kernel[0] = 0.0; kernel[1] = 1.0; kernel[2] = 0.0; kernel[3] = 1.0; kernel[4] = -4.0; kernel[5] = 1.0; kernel[6] = 0.0; kernel[7] = 2.0; kernel[8] = 0.0; */ // Mean Filter // 1 1 1 // 1 1 1 // 1 1 1 /* kernel[0] = 1.0; kernel[1] = 1.0; kernel[2] = 1.0; kernel[3] = 1.0; kernel[4] = 1.0; kernel[5] = 1.0; kernel[6] = 1.0; kernel[7] = 1.0; kernel[8] = 1.0; */ if(gl_TexCoord[0].s<0.5) { // For every pixel sample the neighbor pixels and sum up for( i=0; i<KERNEL_SIZE; i++ ) { // select the pixel with the concerning offset vec4 tmp = texture2D(colorMap, gl_TexCoord[0].st + offset[i]); sum += tmp * kernel[i]; } sum /= 16.0; } else if( gl_TexCoord[0].s>0.51 ) { sum = texture2D(colorMap, gl_TexCoord[0].xy); } else // Draw a red line { sum = vec4(1.0, 0.0, 0.0, 1.0); } gl_FragColor = sum; } Vertex Shader void main(void) { gl_TexCoord[0] = gl_MultiTexCoord0; gl_Position = ftransform(); }

• Dynamic Scoped Resources in WPF/XAML?

  - by firoso

  I have 2 Xaml files, one containing a DataTemplate which has a resource definition for an Image brush, and the other containing a content control which presents this DataTemplate. The data template is bound to a view model class. Everything seems to work EXCEPT the ImageBrush resource, which just shows up white... Any ideas?

• Ruby Rails Mongrel Sever failing to serve OXS1.6

  - by Mark V

  Hi there I'm fairly new to Rails and the Mac, and doing my first deploy... I'm trying to set up my rails app on a brand new Apple mini-server running OXS1.6 (Snow Leopard). It is currently running fine on my new iMac i7 (same OS). I start mongrel with this command: mongrel_rails start -e production -p 3000 -d -a 127.0.0.1 --debug And it starts giving this output in the log/mongrel.log ** Daemonized, any open files are closed. Look at log/mongrel.pid and log/mongrel.log for info. ** Starting Mongrel listening at 127.0.0.1:3000 ** Installing debugging prefixed filters. Look in log/mongrel_debug for the files. ** Starting Rails with production environment... /Library/Ruby/Gems/1.8/gems/rails-2.3.5/lib/rails/gem_dependency.rb:119:Warning: Gem::Dependency#version_requirements is deprecated and will be removed on or after August 2010.

It might not work well. ** Mongrel 1.1.5 available at 127.0.0.1:3000 ** Writing PID file to log/mongrel.pid The output is the same on my dev iMac (including the warnings). The difference is that accessing http://127.0.0.1:3000 on my iMac serves up the app's login page. Where as on the mac mini-server accessing the same results in this error 500 text from mongrel: "We're sorry, but something went wrong." It's as if rails is not working. I'm pretty good at figuring things out if I have some log file messages to direct me, but mongrel.log has no error message (the output remains the same as above), and the log/production.log is empty (which makes me think rails has not started?). My gems are all the same versions between machines and so is the app code; and there are no clues I can see in any of the mongrel_debug logs, except that rails.log on the mac mini-server and the iMac are different. After a start and single access, first is the rails.log from the mac mini-server: D, [2010-04-15T13:45:34.870406 #6914] DEBUG -- : TRACING ON Thu Apr 15 13:45:34 +1200 2010 Thu Apr 15 13:46:08 +1200 2010 REQUEST / --- !map:Mongrel::HttpParams SERVER_NAME: 127.0.0.1 HTTP_ACCEPT: application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5 HTTP_CACHE_CONTROL: max-age=0 HTTP_HOST: 127.0.0.1:3000 HTTP_USER_AGENT: Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10_6_0; en-US) AppleWebKit/533.2 (KHTML, like Gecko) Chrome/5.0.342.9 Safari/533.2 REQUEST_PATH: / SERVER_PROTOCOL: HTTP/1.1 HTTP_ACCEPT_LANGUAGE: en-US,en;q=0.8 REMOTE_ADDR: 127.0.0.1 PATH_INFO: / SERVER_SOFTWARE: Mongrel 1.1.5 SCRIPT_NAME: / HTTP_VERSION: HTTP/1.1 REQUEST_URI: / SERVER_PORT: "3000" HTTP_ACCEPT_CHARSET: ISO-8859-1,utf-8;q=0.7,*;q=0.3 REQUEST_METHOD: GET GATEWAY_INTERFACE: CGI/1.2 HTTP_ACCEPT_ENCODING: gzip,deflate,sdch HTTP_CONNECTION: keep-alive While on my iMac it seems the same except for the addition of the HTTP_COOKIE and the HTTP_IF_NONE_MATCH, here is rails.log from my iMac # Logfile created on Thu Apr 15 13:41:42 +1200 2010 by logger.rb/22285 D, [2010-04-15T13:41:42.934088 #2070] DEBUG -- : TRACING ON Thu Apr 15 13:41:42 +1200 2010 Thu Apr 15 13:42:05 +1200 2010 REQUEST / --- !map:Mongrel::HttpParams SERVER_NAME: 127.0.0.1 HTTP_ACCEPT: application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5 HTTP_HOST: 127.0.0.1:3000 HTTP_USER_AGENT: Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10_6_3; en-US) AppleWebKit/533.2 (KHTML, like Gecko) Chrome/5.0.342.9 Safari/533.2 REQUEST_PATH: / SERVER_PROTOCOL: HTTP/1.1 HTTP_IF_NONE_MATCH: "\"216cc63ce3c1f286ef8dd4f18f354f6e\"" HTTP_ACCEPT_LANGUAGE: en-US,en;q=0.8 REMOTE_ADDR: 127.0.0.1 PATH_INFO: / SERVER_SOFTWARE: Mongrel 1.1.5 SCRIPT_NAME: / HTTP_COOKIE: _ServiceApp_session=BAh7DDonY3VzdG9tZXJfbGlzdF9maWx0ZXJfam9iX3N0YXR1c19pZGn6Og9zZXNzaW9uX2lkIiU0ZTk1ZWZjMmViMGU3NjE2YzA0NDc2YTkxYzJlNDZiOToaY3VycmVudF9jdXN0b21lcl9uYW1lIilUSEUgQ1VTVE9NRVIgTkFNRSBORUVEUyBUTyBCRSBMT0FERUQ6EF9jc3JmX3Rva2VuIjFuT1JMUWk0NlZrWlM3c2lUN3BaWCs5NkhRajhxYnFwRnhzVHVTWXEvUWY0PToZam9iX2xpc3RfZmlsdGVyX3RleHQiADogam9iX2xpc3RfZmlsdGVyX2VtcGxveWVlX2lkafo6HmN1c3RvbWVyX2xpc3RfZmlsdGVyX3RleHQiAA%3D%3D--d01bc5d0b457ad524d16cb3402b5dfed9afce83d HTTP_VERSION: HTTP/1.1 REQUEST_URI: / SERVER_PORT: "3000" HTTP_ACCEPT_CHARSET: ISO-8859-1,utf-8;q=0.7,*;q=0.3 REQUEST_METHOD: GET GATEWAY_INTERFACE: CGI/1.2 HTTP_ACCEPT_ENCODING: gzip,deflate,sdch HTTP_CONNECTION: keep-alive Any direction or ideas would be greatly appreciated.

• LLVM JIT segfaults. What am I doing wrong?

  It is probably something basic because I am just starting to learn LLVM..

• WPF Xaml Custom Styling Selected Item Style in a ListBox

  - by John Batdorf

  I have a list box that scrolls images horizontally. I have the following XAML I used blend to create it. It originally had a x:Key on the Style TaregetType line, MSDN said to remove it, as I was getting errors on that. Now I'm getting this error: Error 3 Operation is not valid while ItemsSource is in use. Access and modify elements with ItemsControl.ItemsSource instead.

• creating a tooltip for a line drawn on cartesiandatacanvas in flex

  - by Guru

  I am trying to draw a line on cartesiandatacanvas. While I am able to draw lines easily using the canvas.moveTo and canvas.lineTo methods, I cannot provide a tooltip to the line if I use that functionality. I have tried creating a label(when ever I draw a line) and adding a tooltip to it but since I show the lines in a 10*10 grid both vertical and horizontal there is a overlap and it is confusing. So now I am trying to create a line object that extends shape or UIComponent. I cannot add this object to canvas using the addChild method it does not work. The addDataChild method works but it messes with the positioning of the line. Can someone help with a solution to this. Simply put I want to draw lines on a datacanvas and add tooltips to them. Here is my code for the line object: package model { import flash.display.CapsStyle; import flash.display.JointStyle; import flash.display.LineScaleMode; import mx.core.UIComponent; public class Line extends UIComponent { public var x1:Number; public var x2:Number; public var y1:Number; public var y2:Number; public var color:Number; public function Line(x1:Number, y1:Number, x2:Number, y2:Number,color:Number) { super(); this.graphics.lineStyle(4, color, 1, true, LineScaleMode.NORMAL, CapsStyle.ROUND, JointStyle.MITER, 1 ); this.graphics.moveTo(x1,y1); this.graphics.lineTo(x2,y2); } } } Here is a sample MXML that has a canvas and tries to use the line object above: <?xml version="1.0" encoding="utf-8"?> <mx:WindowedApplication xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" initialize="init()"> <mx:Script> <![CDATA[ import model.Line; import mx.charts.chartClasses.CartesianCanvasValue; private var accidImage:Image = new Image(); public function init():void { var line:Line = new Line(10,10,40,40,0XFF0000); // canvas.addChild(line); *Does not Work* canvas.addDataChild(line,10,10,null,null,null,null); } ]]> </mx:Script> <mx:Panel x="60" y="53" width="517" height="472" layout="absolute"> <mx:PlotChart x="48" y="10" id="plotchart1"> <mx:series> <mx:PlotSeries displayName="Series 1" yField=""/> </mx:series> <mx:annotationElements> <mx:CartesianDataCanvas id="canvas" includeInRanges="true"/> </mx:annotationElements> <mx:verticalAxis> <mx:LinearAxis id="axis11" minimum="0" maximum="100" interval="10" padding="10"/> </mx:verticalAxis> <mx:horizontalAxis> <mx:LinearAxis id="axis21" minimum="0" maximum="100" interval="10" padding="10"/> </mx:horizontalAxis> </mx:PlotChart> <mx:Legend dataProvider="{plotchart1}"/> </mx:Panel> </mx:WindowedApplication>

• How do I catch this WPF Bitmap loading exception?

  - by mmr

  I'm developing an application that loads bitmaps off of the web using .NET 3.5 sp1 and C#. The loading code looks like: try { CurrentImage = pics[unChosenPics[index]]; bi = new BitmapImage(CurrentImage.URI); // BitmapImage.UriSource must be in a BeginInit/EndInit block. bi.DownloadCompleted += new EventHandler(bi_DownloadCompleted); AssessmentImage.Source = bi; } catch { System.Console.WriteLine("Something broke during the read!"); } and the code to load on bi_DownloadCompleted is: void bi_DownloadCompleted(object sender, EventArgs e) { try { double dpi = 96; int width = bi.PixelWidth; int height = bi.PixelHeight; int stride = width * 4; // 4 bytes per pixel byte[] pixelData = new byte[stride * height]; bi.CopyPixels(pixelData, stride, 0); BitmapSource bmpSource = BitmapSource.Create(width, height, dpi, dpi, PixelFormats.Bgra32, null, pixelData, stride); AssessmentImage.Source = bmpSource; Loading.Visibility = Visibility.Hidden; AssessmentImage.Visibility = Visibility.Visible; } catch { System.Console.WriteLine("Exception when viewing bitmap."); } } Every so often, an image comes along that breaks the reader. I guess that's to be expected. However, rather than being caught by either of those try/catch blocks, the exception is apparently getting thrown outside of where I can handle it. I could handle it using global WPF exceptions, like this SO question. However, that will seriously mess up the control flow of my program, and I'd like to avoid that if at all possible. I have to do the double source assignment because it appears that many images are lacking in width/height parameters in the places where the microsoft bitmap loader expects them to be. So, the first assignment appears to force the download, and the second assignment gets the dpi/image dimensions happen properly. What can I do to catch and handle this exception? Stack trace: at MS.Internal.HRESULT.Check(Int32 hr) at System.Windows.Media.Imaging.BitmapFrameDecode.get_ColorContexts() at System.Windows.Media.Imaging.BitmapImage.FinalizeCreation() at System.Windows.Media.Imaging.BitmapImage.OnDownloadCompleted(Object sender, EventArgs e) at System.Windows.Media.UniqueEventHelper.InvokeEvents(Object sender, EventArgs args) at System.Windows.Media.Imaging.LateBoundBitmapDecoder.DownloadCallback(Object arg) at System.Windows.Threading.ExceptionWrapper.InternalRealCall(Delegate callback, Object args, Boolean isSingleParameter) at System.Windows.Threading.ExceptionWrapper.TryCatchWhen(Object source, Delegate callback, Object args, Boolean isSingleParameter, Delegate catchHandler) at System.Windows.Threading.DispatcherOperation.InvokeImpl() at System.Threading.ExecutionContext.runTryCode(Object userData) at System.Runtime.CompilerServices.RuntimeHelpers.ExecuteCodeWithGuaranteedCleanup(TryCode code, CleanupCode backoutCode, Object userData) at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state) at System.Windows.Threading.DispatcherOperation.Invoke() at System.Windows.Threading.Dispatcher.ProcessQueue() at System.Windows.Threading.Dispatcher.WndProcHook(IntPtr hwnd, Int32 msg, IntPtr wParam, IntPtr lParam, Boolean& handled) at MS.Win32.HwndWrapper.WndProc(IntPtr hwnd, Int32 msg, IntPtr wParam, IntPtr lParam, Boolean& handled) at MS.Win32.HwndSubclass.DispatcherCallbackOperation(Object o) at System.Windows.Threading.ExceptionWrapper.InternalRealCall(Delegate callback, Object args, Boolean isSingleParameter) at System.Windows.Threading.ExceptionWrapper.TryCatchWhen(Object source, Delegate callback, Object args, Boolean isSingleParameter, Delegate catchHandler) at System.Windows.Threading.Dispatcher.InvokeImpl(DispatcherPriority priority, TimeSpan timeout, Delegate method, Object args, Boolean isSingleParameter) at MS.Win32.HwndSubclass.SubclassWndProc(IntPtr hwnd, Int32 msg, IntPtr wParam, IntPtr lParam) at MS.Win32.UnsafeNativeMethods.DispatchMessage(MSG& msg) at System.Windows.Threading.Dispatcher.TranslateAndDispatchMessage(MSG& msg) at System.Windows.Threading.Dispatcher.PushFrameImpl(DispatcherFrame frame) at System.Windows.Application.RunInternal(Window window) at LensComparison.App.Main() in C:\Users\Mark64\Documents\Visual Studio 2008\Projects\LensComparison\LensComparison\obj\Release\App.g.cs:line 48 at System.AppDomain._nExecuteAssembly(Assembly assembly, String[] args) at Microsoft.VisualStudio.HostingProcess.HostProc.RunUsersAssembly() at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state) at System.Threading.ThreadHelper.ThreadStart()

• css problem lining up some icons...

  - by Ronedog

  I'm having a problem lining up some icons and am new enough to css that I'm not exactly sure how to explain this. So I've attached a picture of what the out put is rendering like. I've also included what the css and html code is. Hopefully someone can help point me in the right direction to help fix this. I want the "edit", "archive", "delete" icons to all line up in the right side exactly the same as the first row in the picture. Here is the html: <ul id="nav"> <li>California <div class="portf_edit"> <span> <img src="../images/edit.png"> </span> </div> <div class="portf_archive"> <span> <img src="../images/archive.png"> </span> </div> <div class="portf_delete"> <span> <img src="../images/delete.png"> </span> </div> </li> <li>Hyrum <div class="portf_edit"> <span> <img src="../images/edit.png"> </span> </div> <div class="portf_archive"> <span> <img src="../images/archive.png"> </span> </div> <div class="portf_delete"> <span> <img src="../images/delete.png"> </span> </div> </li> Here is the css: li { list-style-type:none; vertical-align: bottom; list-style-image: none; left:0px; text-align:left; } ul { list-style-type: none; vertical-align: bottom; list-style-image: none; left:0px; } ul#nav{ margin-left:0; padding-left:0px; text-indent:15px; } .portf_edit{ float:right; position: relative; right:50px; display:block; } .portf_archive{ float:right; position: relative; right:-5px; display:block; } .portf_delete{ float:right; position: relative; right: -60px; display:block; } Here's what is being output: Any ideas where to start?

• Implementing ZBar QR Code Reader in UIView

  - by Bobster4300

  I really need help here. I'm pretty new to iOS/Objective-C so sorry if the problem resolution is obvious or if my code is terrible. Be easy on me!! :-) I'm struggling to integrate ZBarSDK for reading QR Codes into an iPad app i'm building. If I use ZBarReaderController (of which there are plenty of tutorials and guides on implementing), it works fine. However I want to make the camera come up in a UIView as opposed to the fullscreen camera. Now I have gotten as far as making the camera view (readerView) come up in the UIView (ZBarReaderView) as expected, but I get an error when it scans a code. The error does not come up until a code is scanned making me believe this is either delegate related or something else. Here's the important parts of my code: (ZBarSDK.h is imported at the PCH file) SignInViewController.h #import <UIKit/UIKit.h> #import <AVFoundation/AVFoundation.h> @class AVCaptureSession, AVCaptureDevice; @interface SignInViewController : UIViewController < ZBarReaderDelegate > { ZBarReaderView *readerView; UITextView *resultText; } @property (nonatomic, retain) UIImagePickerController *imgPicker; @property (strong, nonatomic) IBOutlet UITextView *resultText; @property (strong, nonatomic) IBOutlet ZBarReaderView *readerView; -(IBAction)StartScan:(id) sender; SignInViewController.m #import "SignInViewController.h" @interface SignInViewController () @end @implementation SignInViewController @synthesize resultText, readerView; -(IBAction)StartScan:(id) sender { readerView = [ZBarReaderView new]; readerView.readerDelegate = self; readerView.tracksSymbols = NO; readerView.frame = CGRectMake(30,70,230,230); readerView.torchMode = 0; readerView.device = [self frontFacingCameraIfAvailable]; ZBarImageScanner *scanner = readerView.scanner; [scanner setSymbology: ZBAR_I25 config: ZBAR_CFG_ENABLE to: 0]; [self relocateReaderPopover:[self interfaceOrientation]]; [readerView start]; [self.view addSubview: readerView]; resultText.hidden=NO; } - (void) readerControllerDidFailToRead: (ZBarReaderController*) reader withRetry: (BOOL) retry{ NSLog(@"the image picker failing to read"); } - (void) imagePickerController: (UIImagePickerController*) reader didFinishPickingMediaWithInfo: (NSDictionary*) info { NSLog(@"the image picker is calling successfully %@",info); id<NSFastEnumeration> results = [info objectForKey: ZBarReaderControllerResults]; ZBarSymbol *symbol = nil; NSString *hiddenData; for(symbol in results) hiddenData=[NSString stringWithString:symbol.data]; NSLog(@"the symbols is the following %@",symbol.data); resultText.text=symbol.data; NSLog(@"BARCODE= %@",symbol.data); NSLog(@"SYMBOL : %@",hiddenData); resultText.text=hiddenData; } The error I get when a code is scanned: 2012-12-16 14:28:32.797 QRTestApp[7970:907] -[SignInViewController readerView:didReadSymbols:fromImage:]: unrecognized selector sent to instance 0x1e88b1c0 2012-12-16 14:28:32.799 QRTestApp[7970:907] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[SignInViewController readerView:didReadSymbols:fromImage:]: unrecognized selector sent to instance 0x1e88b1c0' I'm not too worried about what happens with the results just yet, just want to get over this error. Took me ages just to get the camera to come up in the UIView due to severe lack of tutorial or documentation on ZBarReaderView (for beginners anyway). Thanks all.

• CustomListAdapter Problem in Android? Getting ClassCast Exception? How???

  i want to improve the list view's performance. this is the code for my getView method in my Adapter? public View getView(int arg0, View text_view_name, ViewGroup parent) { try { if (text_view_name == null) { text_view_name = mInflater.inflate( R.layout.bs_content_list_item1, null); text_view_name.setTag(R.id.text1_detail1, text_view_name .findViewById(R.id.text1_detail1)); text_view_name.setTag(R.id.text3_detail1, text_view_name .findViewById(R.id.text3_detail1)); text_view_name.setTag(R.id.eve_img_detail1, text_view_name .findViewById(R.id.eve_img_detail1)); } text1 = (TextView) text_view_name.getTag(R.id.text1_detail1); // text2 = (TextView) text_view_name.getTag(R.id.text2); text3 = (TextView) text_view_name.getTag(R.id.text3_detail1); img = (ImageView) text_view_name.getTag(R.id.eve_img_detail1); text1.setText(VAL1[arg0]); text3.setText(VAL3[arg0]); if (!mBusy) { img_value = new URL(VAL4[arg0]); mIcon11 = BitmapFactory.decodeStream(img_value.openConnection() .getInputStream()); img.setImageBitmap(mIcon11); text_view_name.setTag(R.id.eve_img_detail1, null); } else { img.setImageResource(R.drawable.icon); text_view_name.setTag(R.id.eve_img_detail1, text_view_name .findViewById(R.id.eve_img_detail1)); } } catch (Exception e) { name = "Exception in MultiLine_bar_details1 getView"; Log.v(TAG, name + e); } return text_view_name; } this is the code for scrollstatechanged method: public void onScrollStateChanged(AbsListView view, int scrollState) { switch (scrollState) { case OnScrollListener.SCROLL_STATE_IDLE: try { MultiLine_bar_details1.mBusy = false; int first = view.getFirstVisiblePosition(); int count = view.getCount(); for (int i = 0; i < count; i++) { ImageView t = (ImageView) view.getChildAt(i);// here getting the ClassCastException if (t.getTag(R.id.eve_img_detail1) != null) { MultiLine_bar_details1.img_value = new URL( MultiLine_bar_details1.VAL4[first + i]); MultiLine_bar_details1.mIcon11 = BitmapFactory .decodeStream(MultiLine_bar_details1.img_value .openConnection().getInputStream()); MultiLine_bar_details1.img.setImageBitmap(MultiLine_bar_details1.mIcon11); t.setTag(R.id.eve_img_detail1, null); } } } catch (Exception e) { Log.v(TAG, "Idle" + e); } // mStatus.setText("Idle"); break; case OnScrollListener.SCROLL_STATE_TOUCH_SCROLL: MultiLine_bar_details1.mBusy = true; break; case OnScrollListener.SCROLL_STATE_FLING: MultiLine_bar_details1.mBusy = true; break; } } getting the Exception in Idle state: 05-03 16:47:15.201: VERBOSE/BS_Bars(258): Idlejava.lang.ClassCastException: android.widget.LinearLayout this is very complicated for me to get the output properly. actually i have the listview with custom adapter. that icons makes the listview scroll very slow.i am getting the images for icons from the image urls. upto this(above code) i can improve the scroll performance of my list view. but the image icons are not proper in the corresponding order. its dynamically changing when i scroll the listview.. i refered the commonsware busy coder guide and this blog.

• php slideshow sample

  I try to do a simple image slideshow in php (just cycle images, no links, no other effects). after some googling I found the following in net: <HTML> <HEAD> <TITLE>Php Slideshow</TITLE> <script language="javascript"> var speed = 4000; // time picture is displayed var delay = 3; // time it takes to blend to the next picture x = new Array; var y = 0; <?php $tel=0; $tst='.jpg'; $p= "./images"; $d = dir($p); $first = NULL; while (false !== ($entry = $d->read())) { if (stristr ($entry, $tst)) { $entry = $d->path."/".$entry; print ("x[$tel]='$entry';\n"); if ($first == NULL) { $first = $entry; } $tel++; } } $d->close(); ?> function show() { document.all.pic.filters.blendTrans.Apply(); document.all.pic.src = x[y++]; document.all.pic.filters.blendTrans.Play(delay); if (y > x.length - 1) y = 0; } function timeF() { setTimeout(show, speed); } </script> </HEAD> <BODY > <!-- add html code here --> <?php print ("<IMG src='$first' id='pic' onload='timeF()' style='filter:blendTrans()' >"); ?> <!-- add html code here --> </BODY> </HTML> but it displays only the first image from the cycle.
