• What if any free video player for windows can I set a custom frame buffer for streaming over the wifi?

  - by user268883

  I currently use DAUM PLayer (Pot Player) but I have problems streaming video to my laptop unless it is plugged into the network. An easy fix (so I thought) would be to find a player were I could adjust the cache / buffer so say 5 mins+ is read to the local Hdrive and then played from there... I can not work out how to do this in any player I have VLC, MPCHC and DAUM installed. All I want to do is increase the file buffer so X amount of the networkfile is copied to the local drive and then played... so all stuttering is stopped? How do I do this?

• How to create a column containing a string of stars to inidcate levels of a factor in a data frame i

  - by PaulHurleyuk

  (second question today - must be a bad day) I have a dataframe with various columns, inculding a concentration column (numeric), a flag highlighting invalid results (boolean) and a description of the problem (character) dput(df) structure(list(x = c(1, 2, 3, 4, 5, 6, 7, 8, 9, 10), rawconc = c(77.4, 52.6, 86.5, 44.5, 167, 16.2, 59.3, 123, 1.95, 181), reason = structure(c(NA, NA, 2L, NA, NA, NA, 2L, 1L, NA, NA), .Label = c("Fails Acceptance Criteria", "Poor Injection"), class = "factor"), flag = c("False", "False", "True", "False", "False", "False", "True", "True", "False", "False" )), .Names = c("x", "rawconc", "reason", "flag"), row.names = c(NA, -10L), class = "data.frame") I can create a column with the numeric level of the reason column df$level<-as.numeric(df$reason) df x rawconc reason flag level 1 1 77.40 <NA> False NA 2 2 52.60 <NA> False NA 3 3 86.50 Poor Injection True 2 4 4 44.50 <NA> False NA 5 5 167.00 <NA> False NA 6 6 16.20 <NA> False NA 7 7 59.30 Poor Injection True 2 8 8 123.00 Fails Acceptance Criteria True 1 9 9 1.95 <NA> False NA 10 10 181.00 <NA> False NA and here's what I want to do to create a column with 'level' many stars, but it fails df$stars<-paste(rep("*",df$level)sep="",collapse="") Error: unexpected symbol in "df$stars<-paste(rep("*",df$level)sep" df$stars<-paste(rep("*",df$level),sep="",collapse="") Error in rep("*", df$level) : invalid 'times' argument rep("*",df$level) Error in rep("*", df$level) : invalid 'times' argument df$stars<-paste(rep("*",pmax(df$level,0,na.rm=TRUE)),sep="",collapse="") Error in rep("*", pmax(df$level, 0, na.rm = TRUE)) : invalid 'times' argument It seems that rep needs to be fed one value at a time. I feel that this should be possible (and my gut says 'use lapply' but my apply fu is v. poor) ANy one want to try ?

• C# debugging issue: No symbols are loaded for any call stack frame.

  - by Ciaran Bruen

  Hi - I'm trying to step into a method referenced in an external dll from a C# web service dll. I'm developing the web service code and can step into it from my Winforms app. The dll I'm trying to step into from the web service was developed by someone else, and I have the dll and pdb files. When I try to step into it I'm getting the message below: 'No symbols are loaded for any call stack frame. The source code cannot be displayed'. Here is my project setup: .NET 3.5, VS 2008 Professional, IIS 7 running on Vista Ultimate Winforms app WF1.exe, referencing web service dll WS1.dll, in 1 solution on my machine Database access dll DA1.dll compiled by another developer, referenced by WS1.dll DA1.dll and DA1.pdb files located in root directory of WS1 web service project WS1 web service compiled and published to my local IIS, DA1.dll and DA1.pdb files get copied to the IIS WS1 bin directory So far so good and everything works to a point. I break and step into WF1.exe then break and step into a method on WS1.dll no problems. However when I try to step into a method on DA1.dll the error occurs. Any help appreciated. Cheers, Ciaran

• How to scroll the horizontal scrollbar in an iFrame from the parent frame?

  - by Mohammad

  Is there any cross browser way to scroll the horizontal scroll bar of an IFrame with super wide content with Javascript inside the parent frame. Also I need it to be attached to the mouse wheel event. This is what I have so far, it's a bit copy and paste at the moment and doesn't work unfortunately. //var myIframe = document.getElementById('iframeWithWideContent'); //myIframe.onload = function (myIframe) { var mouseWheelEvt = function (e){ var event = e || window.event; if (document.body.doScroll){ document.body.doScroll(event.wheelDelta>0?"left":"right"); }else if ((event.wheelDelta || event.detail) > 0){ document.body.scrollLeft -= 10; }else{ document.body.scrollLeft += 10; } return false; } if ("onmousewheel" in document.body){ document.body.onmousewheel = mouseWheelEvt; }else{ document.body.addEventListener("DOMMouseScroll", mouseWheelEvt); } //}? I probably should uncomment that code, replace document.body with myIframe though I wouldn't know what I'm doing wrong. Demo on JSBIN link fixed Any help from you JavaScript Lords would be very appreciated. Thank you!

• Can Content script set value of a text box within HTML frame? using Google Chrome extensions..

  - by devdreamers

  Hi all, I was working on a very simple extension, where on clicking extension icon, a webpage is opened in a new tab, the webpage has HTML frames, within which lies a textbox. I want to set a value for the same. The webpage which opens has: <HTML> <FRAMESET rows="15%, *" border="0"> <FRAME src="./files/abc.htm" id="abc_frame" name="abc_frame" onload="abcLoad()" scrolling="NO"> </FRAMESET> </HTML> and abc.htm has: <div align="center" valign="bottom" style="font-size: 1em;"> <form onSubmit="javascript:navigate(this);return false;"> <label for="loc">Loc</label>: <input type="text" size="50" id="loc" value="http://google.com"/> <input name="go" type="submit" value="Go" id="loc_go" onclick='navigate(this); return false;'/> </form> </div> how can I replace current textbox value with, say http://yahoo.com ? I guess, Content Script in Chrome extensions is required, but not sure, how/what should be it's code/content. Please guide/help. Thanks a lot. Appreciate it.

• Problem creating calculations 'engine' in two class java calculator

  - by tokee

  i have hit a brick wall whilst attempting to create a two class java calculator but have been unsuccessful so far in getting it working. i have the code for an interface which works and displays ok but creating a seperate class 'CalcEngine' to do the actual calculations has proven to be beyond me. I'd appreciate it if someone could kick start things for me and create a class calcEngine which works with the interface class and allows input when from single button i.e. if one is pressed on the calc then 1 displays onscreen. please note i'm not asking someone to do the whole thing for me as i want to learn and i'm confident i can do the rest including addition subtraction etc. once i get over the obstacle of getting the two classes to communicate. any and all assistance would be very much appreciated. Please see the calcInterface class code below - import java.awt.*; import javax.swing.*; import javax.swing.border.*; import java.awt.event.*; /** *A Class that operates as the framework for a calculator. *No calculations are performed in this section */ public class CalcFrame implements ActionListener { private CalcEngine calc; private JFrame frame; private JTextField display; private JLabel status; /** * Constructor for objects of class GridLayoutExample */ public CalcFrame() { makeFrame(); //calc = engine; } /** * This allows you to quit the calculator. */ // Alows the class to quit. private void quit() { System.exit(0); } // Calls the dialog frame with the information about the project. private void showAbout() { JOptionPane.showMessageDialog(frame, "Group Project", "About Calculator Group Project", JOptionPane.INFORMATION_MESSAGE); } private void makeFrame() { frame = new JFrame("Group Project Calculator"); makeMenuBar(frame); JPanel contentPane = (JPanel)frame.getContentPane(); contentPane.setLayout(new BorderLayout(8, 8)); contentPane.setBorder(new EmptyBorder( 10, 10, 10, 10)); /** * Insert a text field */ display = new JTextField(); contentPane.add(display, BorderLayout.NORTH); //Container contentPane = frame.getContentPane(); contentPane.setLayout(new GridLayout(4, 4)); JPanel buttonPanel = new JPanel(new GridLayout(4, 4)); contentPane.add(new JButton("1")); contentPane.add(new JButton("2")); contentPane.add(new JButton("3")); contentPane.add(new JButton("4")); contentPane.add(new JButton("5")); contentPane.add(new JButton("6")); contentPane.add(new JButton("7")); contentPane.add(new JButton("8")); contentPane.add(new JButton("9")); contentPane.add(new JButton("0")); contentPane.add(new JButton("+")); contentPane.add(new JButton("-")); contentPane.add(new JButton("/")); contentPane.add(new JButton("*")); contentPane.add(new JButton("=")); contentPane.add(new JButton("C")); contentPane.add(buttonPanel, BorderLayout.CENTER); //status = new JLabel(calc.getAuthor()); //contentPane.add(status, BorderLayout.SOUTH); frame.pack(); frame.setVisible(true); } /** * Create the main frame's menu bar. * The frame that the menu bar should be added to. */ private void makeMenuBar(JFrame frame) { final int SHORTCUT_MASK = Toolkit.getDefaultToolkit().getMenuShortcutKeyMask(); JMenuBar menubar = new JMenuBar(); frame.setJMenuBar(menubar); JMenu menu; JMenuItem item; // create the File menu menu = new JMenu("File"); menubar.add(menu); // create the Quit menu with a shortcut "Q" key. item = new JMenuItem("Quit"); item.setAccelerator(KeyStroke.getKeyStroke(KeyEvent.VK_Q, SHORTCUT_MASK)); item.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { quit(); } }); menu.add(item); // Adds an about menu. menu = new JMenu("About"); menubar.add(menu); // Displays item = new JMenuItem("Calculator Project"); item.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { showAbout(); } }); menu.add(item); } /** * An interface action has been performed. * Find out what it was and handle it. * @param event The event that has occured. */ public void actionPerformed(ActionEvent event) { String command = event.getActionCommand(); if(command.equals("0") || command.equals("1") || command.equals("2") || command.equals("3") || command.equals("4") || command.equals("5") || command.equals("6") || command.equals("7") || command.equals("8") || command.equals("9")) { int number = Integer.parseInt(command); calc.numberPressed(number); } else if(command.equals("+")) { calc.plus(); } else if(command.equals("-")) { calc.minus(); } else if(command.equals("=")) { calc.equals(); } else if(command.equals("C")) { calc.clear(); } else if(command.equals("?")) { } // else unknown command. redisplay(); } /** * Update the interface display to show the current value of the * calculator. */ private void redisplay() { display.setText("" + calc.getDisplayValue()); } /** * Toggle the info display in the calculator's status area between the * author and version information. */ }

• How to clear wxpython frame content when dragging a panel?

  - by aF

  Hello, I have 3 panels and I want to make drags on them. The problem is that when I do a drag on one this happens: How can I refresh the frame to happear its color when the panel is no longer there? This is the code that I have to make the drag: def onMouseMove(self, event): (self.pointWidth, self.pointHeight) = event.GetPosition() (self.width, self.height) = self.GetSizeTuple() if (self.pointWidth>100 and self.pointWidth<(self.width-100) and self.pointHeight < 15) or self.parent.dragging: self.SetCursor(wx.StockCursor(wx.CURSOR_SIZING)) """implement dragging""" if not event.Dragging(): self.w = 0 self.h = 0 return self.CaptureMouse() if self.w == 0 and self.h == 0: (self.w, self.h) = event.GetPosition() else: (posw, posh) = event.GetPosition() displacement = self.h - posh self.SetPosition( self.GetPosition() - (0, displacement)) else: self.SetCursor(wx.StockCursor(wx.CURSOR_ARROW)) def onDraggingDown(self, event): if self.pointWidth>100 and self.pointWidth<(self.width-100) and self.pointHeight < 15: self.parent.dragging = 1 self.SetCursor(wx.StockCursor(wx.CURSOR_ARROW)) self.SetBackgroundColour('BLUE') self.parent.SetTransparent(220) self.Refresh() def onDraggingUp(self, event): self.parent.dragging = 0 self.parent.SetTransparent(255) self.SetCursor(wx.StockCursor(wx.CURSOR_ARROW)) and this are the binds for this events: self.Bind(wx.EVT_MOTION, self.onMouseMove) self.Bind(wx.EVT_LEFT_DOWN, self.onDraggingDown) self.Bind(wx.EVT_LEFT_UP, self.onDraggingUp) With this, if I click on the top of the panel, and move down or up, the panel position changes (I drag the panel) to the position of the mouse.

• AS3 How do I stop sound and video when clicking a menu button to go to another frame?

  - by Jennifer Heidelberg

  Hello, I have a problem with my slideshow script. I have embedding a flash video file into my website with this slideshow called monoslideshow, and everything seems to work perfectly. Trouble is, when I am clicking on another menu button that should jump to another frame, it still keeps playing the video and sound while displaying the new menu data. So I will probably need some code that stops the video instantly, when another menu button is clicked. But how do I write it and where do I put it? Here is my actionscript for the video file to show: var loaderSlide:Loader = new Loader(); var monoslideshow:Object; loaderSlide.contentLoaderInfo.addEventListener(Event.COMPLETE, onLoadComplete); addChild(loaderSlide); loaderSlide.load(new URLRequest("monoslideshow.swf")); function onLoadComplete(event:Event):void { monoslideshow = event.target.content; monoslideshow.showLogo = false; monoslideshow.setViewport(new Rectangle(730, 20, 700, 660)); var xml:XML = <album title="TITLE" itemPath="photography/makingoff/" thumbnailPath="thumbnails/"> <contents> <video source="VIDEO.flv" /> </contents> </album> monoslideshow.loadXML(xml); } It would be great to get a solution to this problem, otherwise my website will be kinda messy ;) THANK YOU!!

• Moving x,y position of all array objects every frame in actionscript 3?

  - by Dylan Gallardo

  I have my code setup so that I have an movieclip in my library a class called "block" being duplicated multiple times and added into an array like this: function makeblock(e:Event){ newblock=new block; newblock.x=10; newblock.y=10; addChild(newblock); myarray[counter] = newblock; //adds a newblock object into array counter += 1; } Then I have a loop with a currently primitive way of handling my problem: stage.addEventListener(Event.ENTER_FRAME, gameloop); function gameloop(evt:Event):void { if (moveright==true){ myarray[0].x += 5; myarray[1].x += 5; myarray[2].x += 5 -(and so on)- My question is how can I change x,y values every frame for new objects duplicated into the array, along with the previous ones that were added. Of course with a more elegant way than writing it out myself... array[0].x += 5, array[1], array[2], array[3] etc. Ideally I would like this to go up to 500 or more array objects for one array so obviously I don't want to be writing it out individually haha, I also need it to be consistent with performance so using a for loop or something to loop through the whole array and move each x += 5 wouldn't work would it? Anyway, if anyone has any ideas that'd be great!

• Bluetooth DUN Tethering fails

  - by tacone

  I have an HTC Desire HD, with Android Froyo (2.2) and PDANet installed. I am using Ubuntu 10.10. I cannot tether it over Bluetooth either with Network Manager or BlueMan. (note, I installed Blueman only after failing with NetWork manager, and I even tried the last version from the PPA). With both my device is discovered, paired, setup. But connecting always fail. Network manager says it cannot get the details of my device Blueman says Connection Refused (111) Here are some relevant entries from syslog.

• Recommendations on developing a WPF application without using MVVM or similar

  - by Metro Smurf

  We were building out the next version of an in-house thick-client application using WPF/Prism (Composite Application Library). As we were nearly done with the client our team was put under new management and shortly thereafter: We were then directed to drop the Prism framework to keep things simple. This includes not using any type of Inversion of Control. We were directed to build out the WPF application without using MVVM or similar; and more along the lines of a traditional WinForm application. The idea is that if a developer sees a control in Visual Studio’s designer view, then (s)he should be able to click on the control and see exactly what it's doing without having to traverse through a view-model (or similar). We have now been tasked with building out the WPF application using one primary Window, use a Frame Control to contain the content, and use a Ribbon outside of the frame for the menu items. Reason we were provided to use Frame Control: a. We will show a view in the Frame with a Page (not a user control) and then load the page in the Frame. b. When a new view is to be shown in the Frame, the current view (Page) will be closed/disposed and the new view (Page) will take its place in the Frame. c. When a developer looks at the Page in design view, (s)he will be able to click on any control and see exactly what is being done. Given the restrictions of 1 and 2 above, we’d like to present another method of building out the application that: Can be presented as an alternative to using the “Frame Methodology” (item 3 above) but still provides the same type of functionality. Does not use MVVM (see #1 and #2 above). Provided the direction we’ve been given, any suggestions as to an alternative we can present? I’d request that the responses be kept on the professional level and thank you in advance.

• Sudden issues reading uncompressed video using opencv

  - by JohnSavage

  I have been using a particular pipeline to process video using opencv to encode uncompressed video (fourcc = 0), and opencv python bindings to then open and work on these files. This has been working fine for me on OpenCV 2.3.1a on Ubuntu 11.10 until just a few days ago. For some reason it currently is only allowing me to read the first frame of a given file the first time I open that file. Further frames are not read, and once I touch the file once with my program, it then cannot even read the first frame. More detail: I created the uncompressed video files as follows: out_video.open(out_vid_name, 0, // FOURCC = 0 means record raw fps, Size(640, 480)) Again, these videos worked fine for me until about a week ago. Now, when I try to open one of these I get the following message (from what I think is ffmpeg): Processing video.avi Using network protocols without global network initialization. Please use avformat_network_init(), this will become mandatory later. [avi @ 0x29251e0] parser not found for codec rawvideo, packets or times may be invalid. It reads and displays the first frame fine, but then fails to read the next frame. Then, when I try to run my code on the same video, the capture still opens with the same message as above. However, it cannot even read the very first frame. Here is the code to open the capture: self.capture = cv2.VideoCapture(filename) if not self.capture.isOpened() print "Error: could not open capture" sys.exit() Again, this part is passed without any issue, but then the break happens at: success, rgb = self.capture.read() if not success: print "error: could not read frame" return False This part breaks at the second frame on the first run of the video file, and then on the first frame on subsequent runs. I really don't know where to even begin debugging this. Please help!

• Adding a UIPickerView over a UITabBarController

  - by Kai

  I'm trying to have a UIPickerView slide from the bottom of the screen (over the top of a tab bar) but can't seem to get it to show up. The actual code for the animation is coming from one of Apple's example code projects (DateCell). I'm calling this code from the first view controller (FirstViewController.m) under the tab bar controller. - (IBAction)showModePicker:(id)sender { if (self.modePicker.superview == nil) { [self.view.window addSubview:self.modePicker]; // size up the picker view to our screen and compute the start/end frame origin for our slide up animation // // compute the start frame CGRect screenRect = [[UIScreen mainScreen] applicationFrame]; CGSize pickerSize = [self.modePicker sizeThatFits:CGSizeZero]; CGRect startRect = CGRectMake(0.0, screenRect.origin.y + screenRect.size.height, pickerSize.width, pickerSize.height); self.modePicker.frame = startRect; // compute the end frame CGRect pickerRect = CGRectMake(0.0, screenRect.origin.y + screenRect.size.height - pickerSize.height, pickerSize.width, pickerSize.height); // start the slide up animation [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:0.3]; // we need to perform some post operations after the animation is complete [UIView setAnimationDelegate:self]; self.modePicker.frame = pickerRect; // shrink the vertical size to make room for the picker CGRect newFrame = self.view.frame; newFrame.size.height -= self.modePicker.frame.size.height; self.view.frame = newFrame; [UIView commitAnimations]; // add the "Done" button to the nav bar self.navigationItem.rightBarButtonItem = self.doneButton; }} Whenever this action fires via a UIBarButtonItem that lives in a UINavigationBar (which is all under the FirstViewController) nothing happens. Can anyone please offer some advice?

• python tkinter gui

  - by Lewis Townsend

  I'm wanting to make a small python program for yearly temperatures. I can get nearly everything working in the standard console but I'm wanting to implement it into a GUI. The program opens a csv file reads it into lists, works out the average, and min & max temps. Then on closing the application will save a summary to a new text file. I am wanting the default start up screen to show All Years. When a button is clicked it just shows that year's data. Here is a what I want it to look like. Pretty simple layout with just the 5 buttons and the out puts for each. I can make up the buttons for the top fine with: Code: class App: def __init__(self, master): frame = Frame(master) frame.pack() self.hi_there = Button(frame, text="All Years", command=self.All) self.hi_there.pack(side=LEFT) self.hi_there = Button(frame, text="2011", command=self.Y1) self.hi_there.pack(side=LEFT) self.hi_there = Button(frame, text="2012", command=self.Y2) self.hi_there.pack(side=LEFT) self.hi_there = Button(frame, text="2013", command=self.Y3) self.hi_there.pack(side=LEFT) self.hi_there = Button(frame, text="Save & Exit", command=self.Exit) self.hi_there.pack(side=LEFT) I'm not sure as to how to make the other elements, such as the title & table. I was going to post the code of the small program but decided not to. Once I have the structure/framework I think I can populate the fields & I might learn better this way. Using Python 2.7.3

• MAAttachedWindow hide

  - by Montecorte

  I had the same problem that The-Kenny at this post but I fixed it adding the windowDidResignKey: method on the MAAttachedWindow.m, but now my problem is that when I click outside the StatusBar item keeps blue background and when I click another time on the status item it goes normally and I have to click a second time on it to show the window. I tried to add a method in the CustomView (the view of the status item) that do the same thing that te mouseDown method: - (void)mouseDown:(NSEvent *)event { NSRect frame = [[self window] frame]; NSPoint pt = NSMakePoint(NSMidX(frame), NSMidY(frame)); NSLog(@"%g,%g",pt.x,pt.y); clicked = !clicked; [controller toggleAttachedWindowAtPoint:pt]; [self setNeedsDisplay:YES];} my method is: - (void)windowDidResignKey { NSLog(@"Resigned"); NSRect frame = [[self window] frame]; NSPoint pt = NSMakePoint(NSMidX(frame), NSMidY(frame)); NSLog(@"%g,%g",pt.x,pt.y); clicked = !clicked; [controller toggleAttachedWindowAtPoint:pt]; [self setNeedsDisplay:YES];} I call this method in the windowDidResignKey that I have defined on MAAttachedWindow.m, but this method dont call correctly the toggleAttachedWindowAtPoint method, I dont know exactly why, it's only called when I click another time over the status item If anybody knows how to do that any help would be fine. Thank you so much :)

• wx_ref and custom wx_object's

  - by Iogann

  Hi! I am developing MDI application with help of wxErlang. I have a parent frame, implemented as wx_object: -module(main_frame). -export([new/0, init/1, handle_call/3, handle_event/2, terminate/2]). -behaviour(wx_object). .... And I have a child frame, implemented as wx_object too: module(child_frame). -export([new/2, init/1, handle_call/3, handle_event/2, terminate/2]). -export([save/1]). -behaviour(wx_object). % some public API method save(Frame) -> wx_object:call(Frame, save). .... I want to call save/1 for an active child frame from the parent frame. There is my code: ActiveChild = wxMDIParentFrame:getActiveChild(Frame), case wx:is_null(ActiveChild) of false - child_frame:save(ActiveChild); _ - ignore end This code fails because ActiveChild is #wx_ref{} with state=[], but wx_object:call/2 needs #wx_ref{} where state is set to the pid of the process which we call. What is the right method to do this? I thought only to store a list of all created child frames with its pids in the parent frame and search the pid in this list, but this is ugly.

• Problem setting dynamic UITableViewCell height

  - by HiveHicks

  I've got a UITableView with two dynamic rows. Each of the rows is a subclass of UITableViewCell and is loaded from nib. As my rows contain dynamic content, I use layoutSubviews to reposition all subviews: - (void)layoutSubviews { [super layoutSubviews]; CGFloat initialHeight = titleLabel.bounds.size.height; CGSize constraintSize = CGSizeMake(titleLabel.bounds.size.width, MAXFLOAT); CGSize size = [titleLabel.text sizeWithFont:titleLabel.font constrainedToSize:constraintSize]; CGFloat delta = size.height - initialHeight; CGRect titleFrame = titleLabel.frame; titleFrame.size.height += delta; titleLabel.frame = titleFrame; locationLabel.frame = CGRectOffset(locationLabel.frame, 0, delta); dayLabel.frame = CGRectOffset(dayLabel.frame, 0, delta); timeLabel.frame = CGRectOffset(timeLabel.frame, 0, delta); } The problem is that I can't find a way to determine the height in table view delegate's tableView:heightForRowAtIndexPath: method. The trick is that I load cell from nib, so just after it's loaded titleLabel.bounds.size.width is 300 px (as in nib), not taking into account type of the device (iPhone/iPad) and current orientation, so it seems impossible to calculate the height without conditional checks for orientation and device type. Any ideas?

• Replacing UISplitViewController. New version isn't added for current orientation, frame size

  - by Justin Williams

  My application has two different modes I am switching between by replacing the two views in a UISplitViewController. This involves instantiating the new views and a new UISplitViewController. I then set the new detail view as the UISplitViewController's delegate. I'm running into an issue where when I replace the view controllers and splitview controller, they are not properly sized or added for the current orientation. For instance, if I have my iPad in UIDeviceOrientationPortraitUpsideDown the view will be upside down when I call addSubview, but will rotate to the proper orientation after a second. In another instance, if I have the device in landscape mode and swap the views, the detail view controller is not fully stretched to the size of the view. If I rotate the device to portrait and back to landscape, its resized properly. The code I'm using to create the new split view and view controllers is as follows. - (void)showNotes { teiphoneAppDelegate *appDelegate = (teiphoneAppDelegate *)[[UIApplication sharedApplication] delegate]; [appDelegate.splitViewController.view removeFromSuperview]; OMSavedScrapsController *notesViewController = [[OMSavedScrapsController alloc] initWithNibName:@"SavedScraps" bundle:nil]; UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:notesViewController]; ComposeViewController *noteDetailViewController = [[ComposeViewController alloc] initWithNibName:@"ComposeView-iPad" bundle:nil]; UISplitViewController *newSplitVC = [[UISplitViewController alloc] init]; newSplitVC.viewControllers = [NSArray arrayWithObjects:navController, noteDetailViewController, nil]; newSplitVC.delegate = noteDetailViewController; appDelegate.splitViewController = newSplitVC; // Fade in the new split view appDelegate.splitViewController.view.alpha = 0.0f; [appDelegate.window addSubview:appDelegate.splitViewController.view]; [appDelegate.window makeKeyAndVisible]; [UIView beginAnimations:nil context:appDelegate.window]; [UIView setAnimationDuration: 0.5f]; [UIView setAnimationCurve: UIViewAnimationCurveEaseInOut]; appDelegate.splitViewController.view.alpha = 1.0f; [UIView commitAnimations]; [notesViewController release]; [navController release]; [noteDetailViewController release]; [newSplitVC release]; } Any suggestions for how to get the new splitview to add for the device's current orientation and frame?

• "EXC_BAD_ACCESS: Unable to restore previously selected frame" Error, Array size?

  - by Job

  Hi there, I have an algorithm for creating the sieve of Eratosthenes and pulling primes from it. It lets you enter a max value for the sieve and the algorithm gives you the primes below that value and stores these in a c-style array. Problem: Everything works fine with values up to 500.000, however when I enter a large value -while running- it gives me the following error message in xcode: Program received signal: “EXC_BAD_ACCESS”. warning: Unable to restore previously selected frame. Data Formatters temporarily unavailable, will re-try after a 'continue'. (Not safe to call dlopen at this time.) My first idea was that I didn't use large enough variables, but as I am using 'unsigned long long int', this should not be the problem. Also the debugger points me to a point in my code where a point in the array get assigned a value. Therefore I wonder is there a maximum limit to an array? If yes: should I use NSArray instead? If no, then what is causing this error based on this information? EDIT: This is what the code looks like (it's not complete, for it fails at the last line posted). I'm using garbage collection. /*--------------------------SET UP--------------------------*/ unsigned long long int upperLimit = 550000; // unsigned long long int sieve[upperLimit]; unsigned long long int primes[upperLimit]; unsigned long long int indexCEX; unsigned long long int primesCounter = 0; // Fill sieve with 2 to upperLimit for(unsigned long long int indexA = 0; indexA < upperLimit-1; ++indexA) { sieve[indexA] = indexA+2; } unsigned long long int prime = 2; /*-------------------------CHECK & FIND----------------------------*/ while(!((prime*prime) > upperLimit)) { //check off all multiples of prime for(unsigned long long int indexB = prime-2; indexB < upperLimit-1; ++indexB) { // Multiple of prime = 0 if(sieve[indexB] != 0) { if(sieve[indexB] % prime == 0) { sieve[indexB] = 0; } } } /*---------------- Search for next prime ---------------*/ // index of current prime + 1 unsigned long long int indexC = prime - 1; while(sieve[indexC] == 0) { ++indexC; } prime = sieve[indexC]; // Store prime in primes[] primes[primesCounter] = prime; // This is where the code fails if upperLimit > 500000 ++primesCounter; indexCEX = indexC + 1; } As you may or may not see, is that I am -very much- a beginner. Any other suggestions are welcome of course :)

• KVM/Libvirt bridged/routed networking not working on newer guest kernels

  - by SharkWipf

  I have a dedicated server running Debian 6, with Libvirt (0.9.11.3) and Qemu-KVM (qemu-kvm-1.0+dfsg-11, Debian). I am having a problem getting bridged/routed networking to work in KVM guests with newer kernels (2.6.38). NATted networking works fine though. Older kernels work perfectly fine as well.
