• Why does my computer run slowly and freeze sometimes?

  - by Brae

  EDIT I disabled sound in the BIOS, rebooted and it hung. I removed the (previously) faulty HDD, rebooted and it hung. I have managed to get my Realtek audio manager open again after its mysterious disappearance. Subsequently my microphone is now working again, to fix it I had to uninstall audio drivers, disable audio in BIOS, install audio drivers, enable audio in BIOS. Access via network (with faulty HDD in) seems to not be triggering hangs at the moment. I think with the sound problem fixed it might play a little nicer, but I think its still going to hang. If it does, then I'm fairly sure its been narrowed down to the mobo. EDIT Pretty convinced my motherboard is the culprit, because nothing else seems to have any obvious problems (bar the hard drive, which the PC still hangs without it being plugged in) So thank you all for helping, once I get more rep ill up a few of the answers. My PC is doing some weird things... Sometimes when I open up a program, lets say Adobe Photoshop, it will load everything normally, nice and quick no problems and I can use it fine. Other times its a little odd, and it loads the program as if it's only using half of the CPU. It's pretty obvious when it does it, normally the loading screen skims past, but when it does this weird load you see it slowly tick though each thing, and the program itself becomes incredibly slow. Even Google Chrome does it sometimes. Yet when I exit and reopen the program without doing anything else, it typically opens fine without lagging. I think this problem is probably a symptom of something bigger, because of other problems I'm having. Random hangs; no matter what I have open or what I'm doing. My PC will sort of freeze up for a few seconds. If music is playing it will either loop the last second or two, or it will buzz. This only lasts for a few seconds then it returns to normal without having to restart. During this time all programs lock up and freeze, and the mouse and keyboard are useless. I am also having a weird issue with my audio jacks, without touching my PC at all, sometimes I will see a popup saying that I have unplugged something or plugged something in, neither of which has actually happened. Pretty sure this is cause by the motherboard. I recently had a 'Pink Screen of Death' (yes pink) which pointed to my audio drivers. The lockups seem to happen with some consistency when someone is accessing my shared files via my home LAN. Which leads me to believe either one of my hard drives is acting up or more likely the controller. One of my drives had a bit of a crash before, I used Spinrite and managed to recover my stuff and now the drive appears to be working okay. This is possibly adding to the problems. My best guess is something has gone wrong with my motherboard, possibly a power issue or a chip has died, I really don't know. So what I would like to know is: Have I have missed some obvious diagnostic to help figure out what it is, or should I just bite the bullet and assume its my motherboard acting up and buy a new system? dxdiag[64-bit] - http://pastebin.com/G30kb2TL PSOD (minidump) - http://pastebin.com/aZsv0H56 HWiNFO64 (system info / specs) - http://pastebin.com/X6h3K8g6

• Vista 64-bit, DISK BOOT FAILURE

  - by weka

  So I have this Acer Aspire AX3200-U3600A with Windows Vista (64-bit). Every night I turn it off and turn it back on in the morning. Around three weeks ago, I did a fresh factory reimage. Good as new. Then around two days ago, when I turned it on, I noticed it was running extremly slow. As in, it would often freeze up while I had multiple applications open when it usually never froze up. So I decided to restart my computer. Big mistake. My computer froze right after I clicked shut-down. I waited a while. Nothing. Waited some minutes. Nope. I decided to shut it down by pressing the power button. Here is where the problems begin. When I turned it back on, I saw the Windows logo and loading bar and then it loaded to black. I turned it off again forcefully by power button and then once more... then I got: AMD Data Change... Update New Data to DMI! then later the screen clears and I get: AHCI Option ROM BIOS Revision: 01.05.92 Date: 02-19-2008 Copyright (c) 2006-2008 Phoenix Technologies, LTD Port 01: Reset Port Error!! Port 02: then the screen clears again but this time, this loads from the bottom: Nvidia Boot Agent 249.0542 (copyright stuff... blah blah) PXE-E61: Media test failure, check cable. PXE-M0F: Exiting Nvidia Boot Agent DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER. So I try to go into Safe Mode. Well, first of all it doesn't load as fast. After it loads disk.sys from windows/drivers, it will wait a while (2-3 mins) THEN load. However it loads the Acer eRecovery Management Tool. I have three options: Reset computer to factory default, Restore computer from user's backup, or Exit. However, the top two options are gray and disabled where as the Exit is in blue and definitely clickable. So obviously safe mode is not there... A strong thing to note: In the beginning when all of this started, I did a Boot Windows Normal from pressing f8 and I got to my desktop! It logged me in. I could see the icons on my files. However my desktop was extremely slow as in when I clicked on the Start menu, it would wait a while, then load up the menu with JUST the gradient, no text or icons... so as you can see... it saw my HDD? Also, before anyone says, I have NO USB plugged in. My mouse and keyboard are not USB inputs, I assure you. And this came without a recovery CD AND when I went in BIOS, to change the BOOT ORDER, I did NOT see a CD-ROM option. And when I tried pressing ALT+F10 to get into Acer eRecovery Management, the top two options were disabled as well. But sometimes on start-up, I get: Windows has encountered a problem communicating with a device connected to your computer. This error can be caused by unplugging a removable storage device such as an external USB drive while the device is in use, or by faulty hardware such as a hard drive or CD-ROM drive that is failing. Make sure any removeable storage is properly connected and then restart your computer. If you continue to receive this error message, contact the hardware manufacturer. Status: 0xc00000e9 Info: An unexpected I/O error has occured. Then I tried Last Known Good Configuration Settings, that gives me a BSOD. What should I do/

• Hard drive after PCB swap strange stuff

  - by ramyy

  I’ve done a PCB swap to my HDD. The HDD model is: WD6400AAKS-00A7B2. The original PCB PN matches the new one (first three letter groups), though the cache mismatches (16MB original, 8MB new). The Hardware store that made the swap told me it was hard to do the swap, they have done firmware adaptation. I can see that this firmware version does not match the original, (01.03B01 original, 05.04E05 new). Still I can see that the serial number and model of the drive is correct, the hard drive appeared normal in the BIOS, all the partitions show and everything appears normal. I have encountered three things though, I have left the drive non operated for 2-3 weeks after the swap to avoid corrupting the data or anything else the new PCB might cause, until I buy a new drive and backup the data. I got a drive, and when I powered the old drive manually (I have a laptop, I use a normal desktop power supply and a USB/SATA connector), I heard the motor start and I could hear ticking as if the motor’s somehow struggling to start, and then the motor sound starts again then the ticking, and so on.. I tried powering again it happened again. The third time it started normally and I could see everything normally. I took the chance and copied all the data over to the new drive. When I was done, I powered off the drive (after more than 25 hours of continuous operation), tried to power it up again and it did so normally, and so are the times I powered it up later; but I got very suspicious now. What could be the problem here? And what happened new, it used to power normally after the swap directly? The second thing that happened is that I found size differences with some files; some include movies, songs, (.iso) files for games, and programs. I could find the size is the same, but size on disk is a little more on the new drive for these files. . I’ve tried some of those files (with size differences) they worked fine. They are not too much but still make you suspicious of the integrity of the data copied; one cannot try if all files are working for about (580 GB) worth of data. I tried copying these files on the same partition they exist of the old drive; they are the same in size as when copied to the new drive (allocation unit size not the issue). I took an image of a partition (sector by sector including empty ones) and when I explore it, these file sizes are equal to the original (old drive); I copy them anywhere else their size on disk, increases, i.e becomes equal to the ones I copy from the old drive itself anywhere. Why the size difference and can one trust the integrity of the data?? The third thing is that when I connect my new external USB HDD, the partitions of the old HDD unmount and then mount again. Connected are: (USB mouse + Old HDD) then external HDD. Why that happens?? Considering the following: I compared the SMART reports from after the swap directly and after the copying, no error readings or reallocated sectors where reported. Here they are: http://www.image-share.com/ijpg-1939-219.html I later ran both WD data life guard tests and they came out passed. I’m worried for this drive since I must be sure the data is fine and safe on the new one, and I will consider it backup for the new one, since you can’t trust anything anymore. I hope you can forgive me for the length of the post, but couldn’t ignore any of the details, this hard drive contains very important data to me and I have to deal with the situation with great care.

• Hard drive write speed - finding a lighter antivirus?

  - by Shingetsu

  I recently have been getting a lot of system lag here (for example, the mouse and the display in general take about 15 seconds to react in the worst cases). After a lot of monitoring the resources, I found that the problem mainly happens when too much Disk I/O is being done. Three culprits have been identified: My browser had the highest write I/O with 35,000,000 I/O Write Bytes. Steam had the highest read I/O (when IDLE!!!) with 106,000,000 I/O Read Bytes. My antivirus (in both cases I will soon mention) was the runner up in both cases with: 30,000,000ish write and 80,000,000ish read. The first AV I had was Avast! which I had liked on my previous system. After noticing it taking so much I/O I switched to Panda (supposing it wouldn't use TOO much during idle phase). However it only used a bit less I/O. Just a lot less memory and cpu and somewhat more network. My browser at the moment is Maxthon 3 (which I like a lot). Before this I was running chrome which had similar data and much higher cpu when running in the background was enabled. I'm not going to be running steam all the time and there aren't many alternatives to it. I like my browser very much, but I AM willing to switch if there's an obvious problem (I'm in programming, however I'm not a very good sysadmin, especially not when it comes to windows). Finally, my system almost stops lagging when I turn off the antivirus (and preferably steam) (some remains but once in every 5-6 hours for a few seconds so it isn't a big problem). My question (has a few parts): Is it possible to configure steam to lower it's I/O usage? (and maybe network while we're at it?) Which antivirus (very preferably free) uses lowest I/O while idle (I leave PC alone during active scans so that isn't a problem). Is there an obvious problem with my current browser and, if so, is there a way to fix it or should I switch and, if so, to what? (P.S. I've been on FFox for some time too). Info on system: Windows 7 (32 bit T_T, I am getting a new one in a few months but I want to keep using system during that time though). Hard Drive (main) is a Raid0. (Also have an external 1TB one which contains steam (and steam alone). As such it doesn't get used by much anything other than steam and isn't a very large problem. However steam still uses some I/O of registry) CPU: Intel(R) Core(TM)2 CPU [email protected] RAM: 6GB (3.25GB usable) (this and CPU have little effect as shown in next section) Additional info: Memory usage during problematic times: 44% CPU usage during problematic times: 35% Page File: main drive: system managed. 1TB drive: none. The current system I'm using is about 6 years old and is mainly a place holder while I await the new one in a few months. Final words: this is my 1st post on Super User (this question wouldn't feel right on Stack Overflow where I usually stay). If it doesn't have it's place here please tell me. If anything is wrong with it, same. Edit Technically I'm looking for a live thread detection program with minimal IO usage. I already have good active scan capability: Kaspersky (the free scanner uses the paid database) and MalwareBytes. Edit 2 Noticed another one, it seems that windows media player has been using stuff even when off! Turning it off and restarting now. If the problem is fixed I'll tell you guys. The reason I didn't notice it before was because I didn't have resource manager in front of me at the MOMENT of the problem. Now I did and it was at the very top of the list!

• Monitor randomly shutting down, computer accepting no input, need to restart to get working

  - by Sebastian Lamerichs

  First off, spec list: OS: Windows 7 Ultimate 64-bit SP1 CPU: i7-4820k @ 3.7GHz (stock) GPU: Two 3GB Radeon HD 7970s @ 1.05GHz Mobo: AsRock X79 Extreme6 HDD: 2TB Seagate Barracuda 7200rpm RAM: 16GB quad-channel Kingston 1600MHz PSU: Antec HCG 900W Monitors: Acer S220HQL 1920x1080 + ViewSonic VA2251 1920x1080. Plugged into different GPUs. My problem is that, on a daily-ish basis, my monitors will turn off and not turn back on. My computer will still be running, GPU/CPU/case fans all still going, but the monitors will not turn back on. Additionally, it seems to cease all network activity. It doesn't seem to log any errors at all. I've verified that this is not a monitor issue, as when I press the num/caps/scroll lock buttons on my keyboard, the lights don't change, so the computer is clearly not accepting input. I have noticed a few other people on the internet with this problem, and some have claimed that it was solved by disabling PCI-Express Link State Power Management, but the issue still occurs for me after this. Whilst my CPU and GPUs both run at 100% 24/7, the temperatures are certainly not at dangerous levels, with the CPU averaging 65°C and the GPUs at 70°C and 78°C average. All components are brand new. I have tried forcing MSI Afterburner to start when Windows starts and to force a constant voltage, as this fixed the issue for a few days for another user, but he reported back saying that it had stopped working properly again, so I'm not putting too much faith in this working. Many people have said to adjust display sleep mode settings, but this will clearly not work, as the keyboard lights would still work if the monitors were the issue. The closest I can get to a log file for this issue is the following Folding@Home logs: 14:45:21:WU01:FS00:0x17:Completed 1120000 out of 2000000 steps (56%) 14:46:43:WU00:FS01:0x17:Completed 480000 out of 2000000 steps (24%) 14:46:49:WU01:FS00:0x17:Completed 1140000 out of 2000000 steps (57%) 14:48:30:WU01:FS00:0x17:Completed 1160000 out of 2000000 steps (58%) 14:49:55:WU01:FS00:0x17:Completed 1180000 out of 2000000 steps (59%) As you can see, the second GPU (FS01) stops computation approximately three and a half minutes before the issue occurs (it should be completing 1% every 80-120 seconds), and the first GPU (FS00) continues for a few minutes more before the logs just end. As far as I can tell, the computer has a network failure at the time the first GPU stops working, the latest IRC message I received from this time was at 14:47:58. That being said, there could have just not been any messages between then and 14:50:00, so I'm going to be connecting a laptop to the same bouncer to double-check if it happens again. The GPUs functioned perfectly well in another computer for a significant period of time, so I'm fairly confident that they aren't the issue, which means that this is being caused by either software or the motherboard, or possibly RAM. I really hope it's software. I heard from a forum board that there was a patch from Microsoft that fixed this problem, but "I've forgot which KB it was or the google search terms I used to find the patch, LOL.", so that's not much help. Haven't seen it mentioned by anyone else on about a dozen threads about this issue either. The computer is plugged in via a surge-protected power board, and I've run several other computers and pieces of hardware through it with no issues, so that is not the cause. I have just set the hard disk to never turn off, although I don't believe that that will solve the issue. Strangely, this has only happened when I'm not at the computer (which is actually a minority of the time). Until today it had only happened when I had not been actively using the computer for 6 hours, but today it happened within 10-30 minutes of me last using the computer actively. I have enabled file logging from MSI Afterburner, so hopefully this will shed some light on the issue, but I'm not too optimistic. I've heard that it could be a motherboard problem, but I figured I should ask around before RMAing it. Any help?

• EXTJS 3.2.1 EditorGridPanel - ComboBox with jsonstore

  - by Yoong Kim

  Hi, I am using EXTJS with an editorgridpanel and I am trying to to insert a combobox, populated with JsonStore. Here is a snapshot of my code: THE STORE: kmxgz.ordercmpappro.prototype.getCmpapproStore = function(my_url) { var myStore = new Ext.data.Store({ proxy: new Ext.data.HttpProxy({ url: my_url , method: 'POST' }) , reader: new Ext.data.JsonReader({ root: 'rows', totalProperty: 'total', id: 'list_cmpappro_id', fields: [ {name: 'list_cmpappro_id', mapping: 'list_cmpappro_id'} , {name: 'list_cmpappro_name', mapping: 'list_cmpappro_name'} ] }) , autoLoad: true , id: 'cmpapproStore' , listeners: { load: function(store, records, options){ //store is loaded, now you can work with it's records, etc. console.info('store load, arguments:', arguments); console.info('Store count = ', store.getCount()); } } }); return myStore; }; THE COMBO: kmxgz.ordercmpappro.prototype.getCmpapproCombo = function(my_store) { var myCombo = new Ext.form.ComboBox({ typeAhead: true, lazyRender:false, forceSelection: true, allowBlank: true, editable: true, selectOnFocus: true, id: 'cmpapproCombo', triggerAction: 'all', fieldLabel: 'CMP Appro', valueField: 'list_cmpappro_id', displayField: 'list_cmpappro_name', hiddenName: 'cmpappro_id', valueNotFoundText: 'Value not found.', mode: 'local', store: my_store, emptyText: 'Select a CMP Appro', loadingText: 'Veuillez patienter ...', listeners: { // 'change' will be fired when the value has changed and the user exits the ComboBox via tab, click, etc. // The 'newValue' and 'oldValue' params will be from the field specified in the 'valueField' config above. change: function(combo, newValue, oldValue){ console.log("Old Value: " + oldValue); console.log("New Value: " + newValue); }, // 'select' will be fired as soon as an item in the ComboBox is selected with mouse, keyboard. select: function(combo, record, index){ console.log(record.data.name); console.log(index); } } }); return myCombo; }; The combobox is inserted in an editorgridpanel. There's a renderer like this: Ext.util.Format.comboRenderer = function(combo){ return function(value, metadata, record){ alert(combo.store.getCount()); <== always 0!! var record = combo.findRecord(combo.valueField || combo.displayField, value); return record ? record.get(combo.displayField) : combo.valueNotFoundText; } }; When the grid is displayed the first time, instead of have the displayField, I have : "Value not found." And I have the alert : 0 (alert(combo.store.getCount())) from the renderer. But I can see in the console that the data have been correctly loaded! Even if I try to reload the store from the renderer (combo.store.load();), I still have the alert (0)! But when I select the combo to change the value, I can see the data and when I change the value, I can see the displayFiel! I don't understand what's the problem? Since now several days, I already tried all the solutions I found...but still nothing! Any advice is welcome! Yoong

• jquery ui draggable elements not 'draggable' outside of scrolling div

  - by Stu

  hello all, i am super stumped. i have many elements (floating href tags) in a div with a set height/width, with scroll set to "overflow: auto" in the css. this is the structure of the divs: <div id="tagFun_div_main"> <div id="tf_div_tagsReturn"> <!-- all the draggable elements go in here, the parent div scolls --> </div> <div id=" tf_div_tagsDrop"> <div id="tf_dropBox"></div> </div></div> the parent div's, 'tf_div_tagsReturn' and 'tf_div_tagsDrop' will ultimately float next to each other. here is the jquery which is run after all of the 'draggable' elements have been created with class name 'tag_cell', : $(function() { $(".tag_cell").draggable({ revert: 'invalid', scroll: false, containment: '#tagFun_div_main' }); $("#tf_dropBox").droppable({ accept: '.tag_cell', hoverClass: 'tf_dropBox_hover', activeClass: 'tf_dropBox_active', drop: function(event, ui) { GLOBAL_ary_tf_tags.push(ui.draggable.html()); tagFun_reload(); } }); }); as i stated above, the draggable elements are draggable within div 'tf_div_tagsReturn', but they do not visually drag outside of that parent div. worthy to note, if i am dragging one of the draggable elements, and move the mouse over the droppable div, with id 'tf_dropBox', then the hoverclass is fired, i just can't see the draggable element any more. thank you very much for any advice on helping me find a solution. this is my first run at using jquery, so hopefully i am just missing something super obvious. i've been reading the documentation and searching forums thus far to no prevail :( thank you for your time. UPDATE: many thanks to Jabes88 for providing the solution which allowed me to achieve the functionality i was looking for, here is what my jquery ended up looking like, feel free to critique it, as i am new to jquery. $(function() { $(".tag_cell").draggable({ revert: 'invalid', scroll: false, containment: '#tagFun_div_main', helper: 'clone', start : function() { this.style.display="none"; }, stop: function() { this.style.display=""; } }); $(".tf_dropBox").droppable({ accept: '.tag_cell', hoverClass: 'tf_dropBox_hover', activeClass: 'tf_dropBox_active', drop: function(event, ui) { GLOBAL_ary_tf_tags.push(ui.draggable.html()); tagFun_reload(); } }); });

• WPF Combobox: Autocomplete

  - by user279244

  Hi, I have implemented a Autocomplete enabled Combobox in WPF. It is like below... private void cbxSession_Loaded(object sender, RoutedEventArgs e) { cbxSession.ApplyTemplate(); TextBox textBox = cbxSession.Template.FindName("PART_EditableTextBox", cbxSession) as TextBox; textBox.IsReadOnly = false; if (textBox != null) { textBox.KeyUp += new KeyEventHandler(textBox_KeyUp); textBox.KeyUp += delegate { ///open the drop down and start filtering based on what the user types into the combobox cbxSession.IsDropDownOpen = true; cbxSession.Items.Filter += a => { if (a.ToString().ToUpper().Contains(textBox.Text.ToUpper())) return true; else return false; }; }; } } void textBox_KeyUp(object sender, KeyEventArgs e) { if ((e.Key == System.Windows.Input.Key.Up) || (e.Key == System.Windows.Input.Key.Down)) { e.Handled = true; } else if (e.Key == System.Windows.Input.Key.Enter) { e.Handled = true; cbxSession.IsDropDownOpen = false; } } void textBox_KeyDown(object sender, KeyEventArgs e) { cbxSession.SelectionChanged -= cbxSession_SelectionChanged; if (e.Key == System.Windows.Input.Key.Enter) { e.Handled = true; cbxSession.SelectionChanged += cbxSession_SelectionChanged; } if ((e.Key == System.Windows.Input.Key.Up) || (e.Key == System.Windows.Input.Key.Down)) { e.Handled = true; } } private void cbxSession_DropDownClosed(object sender, EventArgs e) { if (cbxSession.Text != "") { TextBox textBox = cbxSession.Template.FindName("PART_EditableTextBox", cbxSession) as TextBox; if (!cbxSession.Items.Contains(textBox.Text)) { textBox.Text = cbxSession.Text; } } } private void cbxSession_DropDownOpened(object sender, EventArgs e) { cbxSession.Items.Filter += a => { return true; }; } <ComboBox x:Name="cbxSession" Width="260" Canvas.Top="5" Canvas.Left="79" Height="25" Visibility="Visible" SelectionChanged="cbxSession_SelectionChanged" MaxDropDownHeight="200" IsTextSearchEnabled="False" IsEditable="True" IsReadOnly="True" Loaded="cbxSession_Loaded" DropDownClosed="cbxSession_DropDownClosed" StaysOpenOnEdit="True" DropDownOpened="cbxSession_DropDownOpened"> <ComboBox.ItemsPanel> <ItemsPanelTemplate> <VirtualizingStackPanel IsVirtualizing="True" IsItemsHost="True"/> </ItemsPanelTemplate> </ComboBox.ItemsPanel> </ComboBox> But, the problem I am facing is... When I try searching, the first character goes missing. And this happens only once. Secondly, When I am using Arrow buttons to the filtered items, the ComboboxSelectionChanged event is fired. Is there any way to make it fire only on the click of 'Enter'

• WPF CommandParameter is NULL first time CanExecute is called

  - by Jonas Follesø

  I have run into an issue with WPF and Commands that are bound to a Button inside the DataTemplate of an ItemsControl. The scenario is quite straight forward. The ItemsControl is bound to a list of objects, and I want to be able to remove each object in the list by clicking a Button. The Button executes a Command, and the Command takes care of the deletion. The CommandParameter is bound to the Object I want to delete. That way I know what the user clicked. A user should only be able to delete their "own" objects - so I need to do some checks in the "CanExecute" call of the Command to verify that the user has the right permissions. The problem is that the parameter passed to CanExecute is NULL the first time it's called - so I can't run the logic to enable/disable the command. However, if I make it allways enabled, and then click the button to execute the command, the CommandParameter is passed in correctly. So that means that the binding against the CommandParameter is working. The XAML for the ItemsControl and the DataTemplate looks like this: <ItemsControl x:Name="commentsList" ItemsSource="{Binding Path=SharedDataItemPM.Comments}" Width="Auto" Height="Auto"> <ItemsControl.ItemTemplate> <DataTemplate> <StackPanel Orientation="Horizontal"> <Button Content="Delete" FontSize="10" Command="{Binding Path=DataContext.DeleteCommentCommand, ElementName=commentsList}" CommandParameter="{Binding}" /> </StackPanel> </DataTemplate> </ItemsControl.ItemTemplate> </ItemsControl> So as you can see I have a list of Comments objects. I want the CommandParameter of the DeleteCommentCommand to be bound to the Command object. So I guess my question is: have anyone experienced this problem before? CanExecute gets called on my Command, but the parameter is always NULL the first time - why is that? Update: I was able to narrow the problem down a little. I added an empty Debug ValueConverter so that I could output a message when the CommandParameter is data bound. Turns out the problem is that the CanExecute method is executed before the CommandParameter is bound to the button. I have tried to set the CommandParameter before the Command (like suggested) - but it still doesn't work. Any tips on how to control it. Update2: Is there any way to detect when the binding is "done", so that I can force re-evaluation of the command? Also - is it a problem that I have multiple Buttons (one for each item in the ItemsControl) that bind to the same instance of a Command-object? Update3: I have uploaded a reproduction of the bug to my SkyDrive: http://cid-1a08c11c407c0d8e.skydrive.live.com/self.aspx/Code%20samples/CommandParameterBinding.zip

• iPhone UIButton addTarget:action:forControlEvents: not working

  - by Aaron Vegh

  I see there are similar problems posted here, but none of the solutions work for me. Here goes: I have a UIButton instance inside a UIView frame, which is positioned within another UIView frame, which is positioned in the main window UIView. To wit: UIWindow --> UIView (searchView) --> UISearchBar (findField) --> UIView (prevButtonView) --> UIButton (prevButton) --> UIView (nextButtonView) --> UIButton (nextButton) So far, so good: everything is laid out as I want it. However, the buttons aren't accepting user input of any kind. I am using the UIButton method addTarget:action:forControlEvents: and to give you an idea of what I'm doing, here's my code for nextButton: nextButton = [UIButton buttonWithType:UIButtonTypeCustom]; [nextButton setImage:[UIImage imageNamed:@"find_next_on.png"] forState:UIControlStateNormal]; [nextButton setImage:[UIImage imageNamed:@"find_next_off.png"] forState:UIControlStateDisabled]; [nextButton setImage:[UIImage imageNamed:@"find_next_off.png"] forState:UIControlStateHighlighted]; [nextButton addTarget:self action:@selector(nextResult:) forControlEvents:UIControlEventTouchUpInside]; The method nextResult: never gets called, the state of the button doesn't change on touching, and there's not a damned thing I've been able to do to get it working. I assume that there's an issue with all these layers of views: maybe something is sitting on top of my button, but I'm not sure what it could be. In the interest of information overload, I found a bit of code that would print out all my view info. This is what I get for my entire view hierarchy: UIWindow {{0, 0}, {320, 480}} UILayoutContainerView {{0, 0}, {320, 480}} UINavigationTransitionView {{0, 0}, {320, 480}} UIViewControllerWrapperView {{0, 64}, {320, 416}} UIView {{0, 0}, {320, 416}} UIWebView {{0, 44}, {320, 416}} UIScroller {{0, 0}, {320, 416}} UIImageView {{0, 0}, {54, 54}} UIImageView {{0, 0}, {54, 54}} UIImageView {{0, 0}, {54, 54}} UIImageView {{0, 0}, {54, 54}} UIImageView {{-14.5, 14.5}, {30, 1}} UIImageView {{-14.5, 14.5}, {30, 1}} UIImageView {{0, 0}, {1, 30}} UIImageView {{0, 0}, {1, 30}} UIImageView {{0, 430}, {320, 30}} UIImageView {{0, 0}, {320, 30}} UIWebDocumentView {{0, 0}, {320, 21291}} UIView {{0, 0}, {320, 44}} UISearchBar {{10, 8}, {240, 30}} UISearchBarBackground {{0, 0}, {240, 30}} UISearchBarTextField {{5, -2}, {230, 31}} UITextFieldBorderView {{0, 0}, {230, 31}} UIPushButton {{205, 6}, {19, 19}} UIImageView {{10, 8}, {15, 15}} UILabel {{30, 7}, {163, 18}} UIView {{290, 15}, {23, 23}} UIButton {{0, 0}, {0, 0}} UIImageView {{-12, -12}, {23, 23}} UIView {{260, 15}, {23, 23}} UIButton {{0, 0}, {0, 0}} UIImageView {{-12, -12}, {23, 23}} UINavigationBar {{0, 20}, {320, 44}} UINavigationButton {{267, 7}, {48, 30}} UIImageView {{0, 0}, {48, 30}} UIButtonLabel {{11, 7}, {26, 15}} UINavigationItemView {{79, 8}, {180, 27}} UINavigationItemButtonView {{5, 7}, {66, 30}} MBProgressHUD {{0, 0}, {320, 480}} UIActivityIndicatorView {{141, 206}, {37, 37}} UILabel {{117, 247}, {86, 27}} The relevant part is noted above the UINavigationBar section. Anyone have any suggestions? I'm all out. Thanks for reading. Aaron.

• WPF - Overlapping Custom Tabs in a TabControl and ZIndex

  - by Rachel

  Problem I have a custom tab control using Chrome-shaped tabs that binds to a ViewModel. Because of the shape, the edges overlap a bit. I have a function that sets the tabItem's ZIndex on TabControl_SelectionChanged which works fine for selecting tabs, and dragging/dropping tabs, however when I Add or Close a tab via a Relay Command I am getting unusual results. Does anyone have any ideas? Default View http://i193.photobucket.com/albums/z197/Lady53461/tabs_default.jpg Removing Tabs http:/i193.photobucket.com/albums/z197/Lady53461/tabs_removing.jpg Adding 2 or more Tabs in a row http:/i193.photobucket.com/albums/z197/Lady53461/tabs_adding.jpg Code to set ZIndex private void PrimaryTabControl_SelectionChanged(object sender, SelectionChangedEventArgs e) { if (e.Source is TabControl) { TabControl tabControl = sender as TabControl; ItemContainerGenerator icg = tabControl.ItemContainerGenerator; if (icg.Status == System.Windows.Controls.Primitives.GeneratorStatus.ContainersGenerated) { foreach (object o in tabControl.Items) { UIElement tabItem = icg.ContainerFromItem(o) as UIElement; Panel.SetZIndex(tabItem, (o == tabControl.SelectedItem ? 100 : 90 - tabControl.Items.IndexOf(o))); } } } } By using breakpoints I can see that it is correctly setting the ZIndex to what I want it to, however the layout is not displaying the changes. I know some of the changes are in effect because if none of them were working then the tab edges would be reversed (the right tabs would be drawn on top of the left ones). Clicking a tab will correctly set the zindex of all tabs (including the one that should be drawn on top) and dragging/dropping them to rearrange them also renders correctly (which removes and reinserts the tab item). The only difference I can think of is I am using the MVVM design pattern and the buttons that Add/Close tabs are relay commands. Does anyone have any idea why this is happening and how I can fix it?? p.s. I did try setting a ZIndex in my ViewModel and binding to it, however the same thing happens when adding/removing tabs via the relay command. EDIT: Being a new user I couldn't post images and could only post 1 link. Images just show a picture of what the tags render as after each scenario. Adding more then 1 at a time will not reset the zindex of other recently-added tabs so they go behind the tab on the Right, and closing tabs does not correctly render the ZIndex of the SelectedTab that replaces it and it shows up behind the tab on its right.

• Silverlight animation not smooth

  - by Andrej

  Hi, When trying to animate objects time/frame based in Silverlight (in contrast to using something like DoubleAnimation or Storyboard, which is not suitable e.g. for fast paced games), for example moving a spaceship in a particular direction every frame, the movement is jumpy and not really smooth. The screen even seems to tear. There seems to be no difference between CompositionTarget and DistpatcherTimer. I use the following approach (in pseudocode): Register Handler to Tick-Event of a DispatcherTimer In each Tick: Compute the elapsed time from the last frame in milliseconds Object.X += movementSpeed * ellapsedMilliseconds This should result in a smooth movement, right? But it doesn't. Here is an example (Controls: WASD and Mouse): Silverlight Game. Although the effect I described is not too prevalent in this sample, I can assure you that even moving a single rectangle over a canvas produces a jumpy animation. Does someone have an idea how to minimize this. Are there other approaches to to frame based animation exept using Storyboards/DoubleAnimations which could solve this? Edit: Here a quick and dirty approach, animating a rectangle with minimum code (Controls: A and D) Animation Sample Xaml: <Grid x:Name="LayoutRoot" Background="Black"> <Canvas Width="1000" Height="400" Background="Blue"> <Rectangle x:Name="rect" Width="48" Height="48" Fill="White" Canvas.Top="200" Canvas.Left="0"/> </Canvas> </Grid> C#: private bool isLeft = false; private bool isRight = false; private DispatcherTimer timer = new DispatcherTimer(); private double lastUpdate; public Page() { InitializeComponent(); timer.Interval = TimeSpan.FromMilliseconds(1); timer.Tick += OnTick; lastUpdate = Environment.TickCount; timer.Start(); } private void OnTick(object sender, EventArgs e) { double diff = Environment.TickCount - lastUpdate; double x = Canvas.GetLeft(rect); if (isRight) x += 1 * diff; else if (isLeft) x -= 1 * diff; Canvas.SetLeft(rect, x); lastUpdate = Environment.TickCount; } private void UserControl_KeyDown(object sender, KeyEventArgs e) { if (e.Key == Key.D) isRight = true; if (e.Key == Key.A) isLeft = true; } private void UserControl_KeyUp(object sender, KeyEventArgs e) { if (e.Key == Key.D) isRight = false; if (e.Key == Key.A) isLeft = false; } Thanks!

• WPF storyboard animation issue when using VisualBrush

  - by Flack

  Hey guys, I was playing around with storyboards, a flipping animation, and visual brushes. I have encountered an issue though. Below is the xaml and code-behind of a small sample I quickly put together to try to demonstrate the problem. When you first start the app, you are presented with a red square and two buttons. If you click the "Flip" button, the red square will "flip" over and a blue one will appear. In reality, all that is happening is that the scale of the width of the StackPanel that the red square is in is being decreased until it reaches zero and then the StackPanel where a blue square is, whose width is initially scaled to zero, has its width increased. If you click the "Flip" button a few times, the animation looks ok and smooth. Now, if you hit the "Reflection" button, a reflection of the red/blue buttons is added to their respective StackPanels. Hitting the "Flip" button now will still cause the flip animation but it is no longer a smooth animation. The StackPanels width often does not shrink to zero. The width shrinks somewhat but then just stops before being completely invisible. Then the other StackPanel appears as usual. The only thing that changed was adding the reflection, which is just a VisualBrush. Below is the code. Does anyone have any idea why the animations are different between the two cases (stalling in the second case)? Thanks. <Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xml:lang="en-US" xmlns:d="http://schemas.microsoft.com/expression/blend/2006" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d" x:Class="WpfFlipTest.Window1" x:Name="Window" Title="Window1" Width="214" Height="224"> <Window.Resources> <Storyboard x:Key="sbFlip"> <DoubleAnimationUsingKeyFrames BeginTime="00:00:00" Storyboard.TargetName="redStack" Storyboard.TargetProperty="(UIElement.RenderTransform).(ScaleTransform.ScaleX)"> <SplineDoubleKeyFrame KeyTime="00:00:00.4" Value="0"/> </DoubleAnimationUsingKeyFrames> <DoubleAnimationUsingKeyFrames BeginTime="00:00:00.4" Storyboard.TargetName="blueStack" Storyboard.TargetProperty="(UIElement.RenderTransform).(ScaleTransform.ScaleX)"> <SplineDoubleKeyFrame KeyTime="00:00:00.8" Value="1"/> </DoubleAnimationUsingKeyFrames> </Storyboard> <Storyboard x:Key="sbFlipBack"> <DoubleAnimationUsingKeyFrames BeginTime="00:00:00" Storyboard.TargetName="blueStack" Storyboard.TargetProperty="(UIElement.RenderTransform).(ScaleTransform.ScaleX)"> <SplineDoubleKeyFrame KeyTime="00:00:00.4" Value="0"/> </DoubleAnimationUsingKeyFrames> <DoubleAnimationUsingKeyFrames BeginTime="00:00:00.4" Storyboard.TargetName="redStack" Storyboard.TargetProperty="(UIElement.RenderTransform).(ScaleTransform.ScaleX)"> <SplineDoubleKeyFrame KeyTime="00:00:00.8" Value="1"/> </DoubleAnimationUsingKeyFrames> </Storyboard> </Window.Resources> <Grid x:Name="LayoutRoot" Background="Gray"> <Grid.RowDefinitions> <RowDefinition Height="Auto"/> <RowDefinition Height="Auto"/> </Grid.RowDefinitions> <Grid.ColumnDefinitions> <ColumnDefinition Width="Auto"/> <ColumnDefinition Width="Auto"/> </Grid.ColumnDefinitions> <StackPanel Name="redStack" Grid.Row="0" Grid.Column="0" RenderTransformOrigin="0.5,0.5"> <StackPanel.RenderTransform> <ScaleTransform/> </StackPanel.RenderTransform> <Border Name="redBorder" BorderBrush="Transparent" BorderThickness="4" Width="Auto" Height="Auto"> <Button Margin="0" Name="redButton" Height="75" Background="Red" Width="105" /> </Border> <Border Width="{Binding ElementName=redBorder, Path=ActualWidth}" Height="{Binding ElementName=redBorder, Path=ActualHeight}" Opacity="0.2" BorderBrush="Transparent" BorderThickness="4" Name="redRefelction" Visibility="Collapsed"> <Border.OpacityMask> <LinearGradientBrush StartPoint="0,0" EndPoint="0,1"> <LinearGradientBrush.GradientStops> <GradientStop Offset="0" Color="Black"/> <GradientStop Offset=".6" Color="Transparent"/> </LinearGradientBrush.GradientStops> </LinearGradientBrush> </Border.OpacityMask> <Border.Background> <VisualBrush Visual="{Binding ElementName=redButton}"> <VisualBrush.Transform> <ScaleTransform ScaleX="1" ScaleY="-1" CenterX="52.5" CenterY="37.5" /> </VisualBrush.Transform> </VisualBrush> </Border.Background> </Border> </StackPanel> <StackPanel Name="blueStack" Grid.Row="0" Grid.Column="0" RenderTransformOrigin="0.5,0.5"> <StackPanel.RenderTransform> <ScaleTransform ScaleX="0"/> </StackPanel.RenderTransform> <Border Name="blueBorder" BorderBrush="Transparent" BorderThickness="4" Width="Auto" Height="Auto"> <Button Grid.Row="0" Grid.Column="1" Margin="0" Width="105" Background="Blue" Name="blueButton" Height="75"/> </Border> <Border Width="{Binding ElementName=blueBorder, Path=ActualWidth}" Height="{Binding ElementName=blueBorder, Path=ActualHeight}" Opacity="0.2" BorderBrush="Transparent" BorderThickness="4" Name="blueRefelction" Visibility="Collapsed"> <Border.OpacityMask> <LinearGradientBrush StartPoint="0,0" EndPoint="0,1"> <LinearGradientBrush.GradientStops> <GradientStop Offset="0" Color="Black"/> <GradientStop Offset=".6" Color="Transparent"/> </LinearGradientBrush.GradientStops> </LinearGradientBrush> </Border.OpacityMask> <Border.Background> <VisualBrush Visual="{Binding ElementName=blueButton}"> <VisualBrush.Transform> <ScaleTransform ScaleX="1" ScaleY="-1" CenterX="52.5" CenterY="37.5" /> </VisualBrush.Transform> </VisualBrush> </Border.Background> </Border> </StackPanel> <Button Grid.Row="1" Click="FlipButton_Click" Height="19.45" HorizontalAlignment="Left" VerticalAlignment="Top" Width="76">Flip</Button> <Button Grid.Row="0" Grid.Column="1" Click="ReflectionButton_Click" Height="19.45" HorizontalAlignment="Left" VerticalAlignment="Top" Width="76">Reflection</Button> </Grid> </Window> Here are the button click handlers: using System;

redRefelction.Visibility = Visibility.Collapsed; blueRefelction.Visibility = Visibility.Collapsed; } else { reflection = true; redRefelction.Visibility = Visibility.Visible; blueRefelction.Visibility = Visibility.Visible; } } } } UPDATE: I have been testing this some more to try to find out what is causing the issue I am seeing and I believe I found what is causing the issue. Below I have pasted new xaml and code-behind. The new sample below is very similar to the original sample, with a few minor modifications. The xaml basically consists of two stack panels, each containing two borders. The second border in each stack panel is a visual brush (a reflection of the border above it). Now, when I click the "Flip" button, one stack panel gets its ScaleX reduced to zero, while the second stack panel, whose initial ScaleX is zero, gets its ScaleX increased to 1. This animation gives the illusion of flipping. There are also two textblocks which display the scale factor of each stack panel. I added those to try to diagnose my issue. The issue is (as described in the oringal post) that the flipping animation is not smooth. Every time I hit the flip button, the animation starts but whenever the ScaleX factor gets to around .14 to .16, the animation looks like it stalls and the stack panels never have there ScaleX reduced to zero, so they never totally disappear. Now, the strange thing is that if I change the Width/Height properties of the "frontBorder" and "backBorder" borders defined below to use explict values instead of Auto, such as Width=105 and Height=75 (to match the button in the border) everything works fine. The animation stutters the first two or three times I run it but after that the flips are smooth and flawless. (BTW, when an animation is run for the first time, is there something going on in the background, some sort of initialization, that causes it to be a little slow the first time?) Is it possible that the Auto Width/Height of the borders are causing the issue? I can reproduce it everytime but I am not sure why Auto Width/Height would be a problem. Below is the sample. Thanks for the help. <Window x:Class="FlipTest.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window1" Height="300" Width="300"> <Window.Resources> <Storyboard x:Key="sbFlip"> <DoubleAnimationUsingKeyFrames BeginTime="00:00:00" Storyboard.TargetName="front" Storyboard.TargetProperty="(UIElement.RenderTransform).(ScaleTransform.ScaleX)"> <SplineDoubleKeyFrame KeyTime="00:00:00.5" Value="0"/> </DoubleAnimationUsingKeyFrames> <DoubleAnimationUsingKeyFrames BeginTime="00:00:00.5" Storyboard.TargetName="back" Storyboard.TargetProperty="(UIElement.RenderTransform).(ScaleTransform.ScaleX)"> <SplineDoubleKeyFrame KeyTime="00:00:00.5" Value="1"/> </DoubleAnimationUsingKeyFrames> </Storyboard> <Storyboard x:Key="sbFlipBack"> <DoubleAnimationUsingKeyFrames BeginTime="00:00:00" Storyboard.TargetName="back" Storyboard.TargetProperty="(UIElement.RenderTransform).(ScaleTransform.ScaleX)"> <SplineDoubleKeyFrame KeyTime="00:00:00.5" Value="0"/> </DoubleAnimationUsingKeyFrames> <DoubleAnimationUsingKeyFrames BeginTime="00:00:00.5" Storyboard.TargetName="front" Storyboard.TargetProperty="(UIElement.RenderTransform).(ScaleTransform.ScaleX)"> <SplineDoubleKeyFrame KeyTime="00:00:00.5" Value="1"/> </DoubleAnimationUsingKeyFrames> </Storyboard> </Window.Resources> <Grid x:Name="LayoutRoot" Background="White" ShowGridLines="True"> <Grid.RowDefinitions> <RowDefinition Height="Auto"/> <RowDefinition Height="Auto"/> <RowDefinition Height="Auto"/> <RowDefinition Height="Auto"/> </Grid.RowDefinitions> <Grid.ColumnDefinitions> <ColumnDefinition Width="Auto"/> <ColumnDefinition Width="Auto"/> </Grid.ColumnDefinitions> <StackPanel x:Name="front" RenderTransformOrigin="0.5,0.5"> <StackPanel.RenderTransform> <ScaleTransform/> </StackPanel.RenderTransform> <Border Name="frontBorder" BorderBrush="Yellow" BorderThickness="2" Width="Auto" Height="Auto"> <Button Margin="0" Name="redButton" Height="75" Background="Red" Width="105" Click="FlipButton_Click"/> </Border> <Border Width="{Binding ElementName=frontBorder, Path=ActualWidth}" Height="{Binding ElementName=frontBorder, Path=ActualHeight}" Opacity="0.2" BorderBrush="Transparent"> <Border.OpacityMask> <LinearGradientBrush StartPoint="0,0" EndPoint="0,1"> <LinearGradientBrush.GradientStops> <GradientStop Offset="0" Color="Black"/> <GradientStop Offset=".6" Color="Transparent"/> </LinearGradientBrush.GradientStops> </LinearGradientBrush> </Border.OpacityMask> <Border.Background> <VisualBrush Visual="{Binding ElementName=frontBorder}"> <VisualBrush.Transform> <ScaleTransform ScaleX="1" ScaleY="-1" CenterX="52.5" CenterY="37.5" /> </VisualBrush.Transform> </VisualBrush> </Border.Background> </Border> </StackPanel> <StackPanel x:Name="back" RenderTransformOrigin="0.5,0.5"> <StackPanel.RenderTransform> <ScaleTransform ScaleX="0"/> </StackPanel.RenderTransform> <Border Name="backBorder" BorderBrush="Yellow" BorderThickness="2" Width="Auto" Height="Auto"> <Button Margin="0" Width="105" Background="Blue" Name="blueButton" Height="75" Click="FlipButton_Click"/> </Border> <Border Width="{Binding ElementName=backBorder, Path=ActualWidth}" Height="{Binding ElementName=backBorder, Path=ActualHeight}" Opacity="0.2" BorderBrush="Transparent"> <Border.OpacityMask> <LinearGradientBrush StartPoint="0,0" EndPoint="0,1"> <LinearGradientBrush.GradientStops> <GradientStop Offset="0" Color="Black"/> <GradientStop Offset=".6" Color="Transparent"/> </LinearGradientBrush.GradientStops> </LinearGradientBrush> </Border.OpacityMask> <Border.Background> <VisualBrush Visual="{Binding ElementName=backBorder}"> <VisualBrush.Transform> <ScaleTransform ScaleX="1" ScaleY="-1" CenterX="52.5" CenterY="37.5" /> </VisualBrush.Transform> </VisualBrush> </Border.Background> </Border> </StackPanel> <Button Grid.Row="1" Click="FlipButton_Click" Height="19.45" HorizontalAlignment="Left" VerticalAlignment="Top" Width="76">Flip</Button> <TextBlock Grid.Row="2" Grid.Column="0" Foreground="DarkRed" Height="19.45" HorizontalAlignment="Left" VerticalAlignment="Top" Width="76" Text="{Binding ElementName=front, Path=(UIElement.RenderTransform).(ScaleTransform.ScaleX)}"/> <TextBlock Grid.Row="3" Grid.Column="0" Foreground="DarkBlue" Height="19.45" HorizontalAlignment="Left" VerticalAlignment="Top" Width="76" Text="{Binding ElementName=back, Path=(UIElement.RenderTransform).(ScaleTransform.ScaleX)}"/> </Grid> </Window> Code-behind: using System;

• Mac - Flash file not loaded in independent flash player

  - by Mugdha

  Hi, I am working on an independent application to play flash files on Mac. I have already done the same for Linux, and it works flawlessly but on mac for some reason flash is not drawing to my window. It is not throwing any kind of error too. I am using Flash player 10, that would mean that I am using the Core Graphics drawing model. I am able to send mouse events to flash and wrote a sample plugin to check if there was a problem in the context that I was sending, but my sample plugin draws properly to the window. I am getting a call for NPN_InvalidateRect twice and as a response I send an update Event back to flash. I drew a dummy rectangle to check that my context is correct. I have flipped the context to make the origin as top left corner. On doing right click on the debug version of the flash player it shows the following message: "Movie not loaded..." Can anyone give me any idea why is the content not being drawn? I would really appreciate the help, as I have been struggling with it for more than a month now. Here is a small log of the interaction that I have with flash: NPN_UserAgent Called NPN_GetValue Called with variable NPNVWindowNPObject; return NULL NPN_GetValue Called with variable NPNVWindowNPObject; return NULL NPN_GetValue Called with variable NPNVSupportsWindowless; return true NPN_SetValue Called for Variable - NPPVpluginTransparentBool; return true NPN_GetValue Called with variable NPNVsupportsCoreGraphicsBool; return true NPN_SetValue Called for Variable - NPNVpluginDrawingModel NPP_SetWindow (CoreGraphics): 0, window=0xebaa90, context=0xe4c930, window.x:0 window.y:22 window.width:480 window.height:270 NPP_HandleEvent(activateEvent) accepted:0 isActive: 1 NPP_HandleEvent(updateEvt) accepted: 1 NPN_UserAgent Called NPN_GetURLNotify Called with URL - javascript:top.location+"flashplugin_unique" NPN_GetValue Called with variable NPNVWindowNPObject; return NULL NPP_NewStream URL=/Users/mjain/Desktop/clock.swf MIME=application/x-shockwave-flash error=0 NPP_WriteReady responseURL=/Users/mjain/Desktop/clock.swf bytes=268435455 NPN_InvalidateRect Called NPP_Write responseURL=/Users/mjain/Desktop/clock.swf bytes=9925 total-delivered=9925/9925 NPP_WriteReady responseURL=/Users/mjain/Desktop/clock.swf bytes=268435455 NPP_DestroyStream responseURL=/Users/mjain/Desktop/clock.swf error=0 NPP_HandleEvent(updateEvt) accepted: 1 NPN_InvalidateRect Called NPP_HandleEvent(updateEvt) accepted: 1 NPP_NewStream URL=javascript:top.location+"flashplugin_unique" MIME=text/plain error=0 NPP_WriteReady responseURL=javascript:top.location+"flashplugin_unique" bytes=16000 NPN_UserAgent Called NPP_Write responseURL=javascript:top.location+"flashplugin_unique" bytes=52 total-delivered=52/52 NPP_WriteReady responseURL=javascript:top.location+"flashplugin_unique" bytes=16000 NPP_DestroyStream responseURL=javascript:top.location+"flashplugin_unique" error=0 NPP_URLNotify responseURL=javascript:top.location+"flashplugin_unique" reason=0 Thanks Mugdha.

• popView from UITabBarController inside UINavigationController

  - by Manu

  Hi, I'm building an application based on the Utility template from Xcode, to which I have added some more views. My application structure would be as follows: MainView (the app menu) Flip-side view (a calculator) UINavigationController Settings view viewDiDLoad: UITabBarController - Tab1 view (options) - Tab2 view (information text) I can navigate correctly from my MainView to my Flip-side view, which is also the root view of the Navigation Controller. From my Flip-side view, I push a second view of my Navigation Controller (Settings view) that is configured to show an UITabBarController, with two tabs, as soon as it loads (with viewDidLoad). If I remove the UITabBarController, I can return with no problems to my Flip-side view using "popViewController" from my Settings view. The problem comes if I load the UITabBarController in viewDiDLoad in my Settings view... the tabs work perfectly, but I'm not able to return to my Flip-side view (root view of the Navigation Controller) anymore. I CAN return if I use the Navigation Bar of the Navigation Controller, but I want to configure my own buttons and have the Navigation Bar hidden. So far I've tried the following methods: [self.navigationController popViewControllerAnimated:YES]; [self.navigationController popToRootViewControllerAnimated:YES]; [self.navigationController popToViewController:FlipSideViewController animated:YES]; But they don't seem to work. The first two just do nothing (the screen remains as it was), and the third one does not recognize the "FlipsideViewController" (maybe because it's a delegate of the MainViewController?). Is there a way to check what is exactly doing the "back" button of the Navigation Bar if I activate it? Should I be using delegates? Can I call a popViewController method in my Settings view from any of the two Tab views? This is my Flip-side view: - (IBAction)showSettingsView { SettingsViewController *controller = [[SettingsViewController alloc] initWithNibName:@"SettingsView" bundle:nil]; controller.title = @"Settings"; [self.navigationController pushViewController:controller animated:YES]; [controller release]; } This is my Settings view: - (void)viewDidLoad { [super viewDidLoad]; tabBarController = [[UITabBarController alloc] init]; Tab1ViewController* vc1 = [[Tab1ViewController alloc] init]; Tab2ViewController* vc2 = [[Tab2ViewController alloc] init]; NSArray* controllers = [NSArray arrayWithObjects:vc1, vc2, nil]; tabBarController.viewControllers = controllers; [self.view addSubview:tabBarController.view]; } And the method to return in one of the Tab views: - (IBAction)backFromTab1View { [self.navigationController popToViewController:FlipSideViewController animated:YES]; } Thanks very much and sorry if the question is too basic!

• facebook connect for android returns a blank login screen?

  - by jonney

  Hi, i am trying to use the old facebook connect authentication to authenticate my android client to get the necessary session id's and other credentials thats needed to start using the web service of facebook. the issue i am having is that when my android application launces and tries to load the login page for facebook, that very same login page is blank and it only displays the the facebook logo as the title of the screen. No login fields or buttons are visible leaving me nowhere to login and authenticate a user. i have tried two API's one is facebook connect api for android http://code.google.com/p/fbconnect-android/ and the other one is the official android facebook sdk that is recommended to be used instead of the previous one i have just mentioned https://github.com/facebook/facebook-android-sdk/ . please see the image below of how it looks like on my app. Here is code that uses the latest android sdk facebook: /** * Authenticate facebook network */ private void authenticateFacebook() { // TODO: move this away from this activty class into some kind of // helper/wrapper class Log.d(TAG, "Clicked on the facebook"); Facebook facebook = new Facebook(OAUTH_KEY_FACEBOOK_API); facebook.authorize(this, new AuthorizeListener()); } class AuthorizeListener implements DialogListener{ @Override public void onComplete(Bundle values) { // TODO Auto-generated method stub Log.d(TAG, "finished authorizing facebook user"); } @Override public void onFacebookError(FacebookError e) { // TODO Auto-generated method stub } @Override public void onError(DialogError e) { // TODO Auto-generated method stub } @Override public void onCancel() { // TODO Auto-generated method stub } } And a simple example of how to use it: http://developers.facebook.com/docs/guides/mobile/ My code is more or less identical to the above example. edit: i did not catch what logcat was inputing in my first attempted at my code above but their was no exceptions or warnings thrown at the time. just a blank page. i then tried it again and diddnt touch my code and what happens now is that a loading dialogue view pops up and stays their for a few minutes until the facebook windows disapears and the logcat outputs the error below: 11-18 17:26:19.913: DEBUG/Facebook-WebView(783): Webview loading URL: https://www.facebook.com/dialog/oauth?type=user_agent&redirect_uri=fbconnect%3A%2F%2Fsuccess&display=touch&client_id=e??????????????????? 11-18 17:27:01.756: DEBUG/Facebook-authorize(783): Login failed: com.kc.unity.agent.util.oauth.facebook.DialogError: The connection to the server was unsuccessful. 11-18 17:27:01.783: DEBUG/Facebook-WebView(783): Webview loading URL: https://www.facebook.com/dialog/oauth?type=user_agent&redirect_uri=fbconnect%3A%2F%2Fsuccess&display=touch&client_id=??????????????? please note that the client id i have amended for obvious reasons but the rest of the logcat is untouched

• Attaching .swf assets to Flex3 by calling getDefinitionByName()

  - by Alexander Farber

  Hello! Does anybody please know, how could you attach symbols from an .swf file in the Actionscript part of your Flex3 file? I've prepared a simple test case demonstrating my problem. Everything works (there are icons at the 4 buttons, there is a red circle) - except the getDefinitionByName() part. My target is to attach a symbol from library "dynamically" - i.e. depending at the value of the suit variable at the runtime. Thank you, Alex Symbols.as: package { public class Symbols { [Embed('../assets/symbols.swf', symbol='spades')] public static const SPADES:Class; [Embed('../assets/symbols.swf', symbol='clubs')] public static const CLUBS:Class; [Embed('../assets/symbols.swf', symbol='diamonds')] public static const DIAMONDS:Class; [Embed('../assets/symbols.swf', symbol='hearts')] public static const HEARTS:Class; } } TestCase.mxml: <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" creationComplete="onCreationComplete();"> <mx:Script> <![CDATA[ private function onCreationComplete():void { var sprite:Sprite = new Sprite(); var g:Graphics = sprite.graphics; g.lineStyle(1, 0xFF0000); g.beginFill(0xFF0000); g.drawCircle(100, 100, 20); g.endFill(); spriteHolder.addChild(sprite); // XXX stuff below not working, can it be fixed? var suit:String = "SPADES"; var mc:MovieClip = new (getDefinitionByName("Symbols.SPADES") as Class); spriteHolder.addChild(mc); } ]]> </mx:Script> <mx:VBox width="100%"> <mx:Button label="1" icon="{Symbols.SPADES}" /> <mx:Button label="2" icon="{Symbols.CLUBS}" /> <mx:Button label="3" icon="{Symbols.DIAMONDS}" /> <mx:Button label="4" icon="{Symbols.HEARTS}" /> <mx:UIComponent id="spriteHolder" width="200" height="200"/> </mx:VBox> </mx:Application>

• Right-click context menu for Java JTree?

  - by arcanex

  I'm trying to implement pop-up menus in Java JTree. I've sub-classed DefaultTreeCellRenderer (to change node appearance) and DefaultTreeCellEditor (to create Components to attach event listeners to, since apparently the Components that DefaultTreeCellRenderer.getTreeCellRendererComponent() returns can't do it?). I don't really want to "edit" the nodes, just be able to pop-up a menu when a node gets right-clicked, but this is the only way I can think of doing it right now... Below is the code that I have so far-- I'm just trying to figure out how to capture MouseEvents. It sort of works, but badly. What's a better way to accomplish what I'm trying to do here? private class My_TreeCellRenderer extends DefaultTreeCellRenderer { My_TreeCellRenderer() { super (); } public Component getTreeCellRendererComponent(JTree tree, Object value, boolean selected, boolean expanded, boolean leaf, int row, boolean hasFocus) { super.getTreeCellRendererComponent(tree, value, selected, expanded, leaf, row, hasFocus); // set label text and tool tips setText(((My_Object)value).getTreeLabel()); setToolTipText(((My_Object)value).getTreeToolTip()); return this; } } private class My_TreeCellEditor extends DefaultTreeCellEditor { private MouseAdapter ma; My_TreeCellEditor(JTree tree, DefaultTreeCellRenderer renderer) { super (tree, renderer); ma = new MouseAdapter() { public void mousePressed(MouseEvent e) { if (e.isPopupTrigger()) { System.out.println("My Popup"); } } public void mouseReleased(MouseEvent e) { if (e.isPopupTrigger()) { System.out.println("My Popup"); } } }; } public Component getTreeCellEditorComponent(JTree tree, Object value, boolean selected, boolean expanded, boolean leaf, int row) { String src_filename = null; // return non-editing component Component c = renderer.getTreeCellRendererComponent(tree, value, selected, expanded, leaf, row, true); // add mouse listener if it's not listening already MouseListener mouseListeners[] = c.getMouseListeners(); int i; for (i=0; i < mouseListeners.length && mouseListeners[i] != ma; i++); if (i >= mouseListeners.length) c.addMouseListener(ma); return c; } protected boolean canEditImmediately(EventObject event) { if (event instanceof MouseEvent && ((MouseEvent)event).getClickCount() == 1) return true; else return false; } }

• popViewControllerAnimated not working, but back button works

  - by Manu

  Hi, I am creating an application based on the Utility template. The main screen consists of a menu with several buttons, each of which creates a different flip-side view. In one of those flip-side views I also configured a Navigation Controller, which works perfectly as long as I have the NavigationBar activated... I can push the view but I have to use the "back" button to return to my flip-side view, which would be the root of the Navigation Controller. The problem comes if I try to go back using "popViewControllerAnimated", properly configured with a button, instead of the "back" button of the NavigationBar. My application crashes for some reason and I am not able to understand why. I could just use the "back" button in the NavigationBar and forget about the problem, but I would prefer to have my own button in order to go back. My app consists of the following: My APPDelegate.m: - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { MenuViewController *menuController = [[MenuViewController alloc] initWithNibName:@"MenuView" bundle:nil]; self.menuViewController = menuController; [menuController release]; menuViewController.view.frame = [UIScreen mainScreen].applicationFrame; [window addSubview:[menuViewController view]]; [window makeKeyAndVisible]; return YES; } MenuViewController.m starting my flip-side view: - (IBAction)showFuelUpliftView { FuelUpliftViewController *controller = [[FuelUpliftViewController alloc] initWithNibName:@"FuelUpliftView" bundle:nil]; controller.delegate = self; controller.title = @"Fuel Uplift"; UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:controller]; [navController setNavigationBarHidden: NO]; navController.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal; [self presentModalViewController:navController animated:YES]; [navController release]; [controller release]; } FuelUpliftViewController.m, where I push the second view of the NavigationController with a button: - (IBAction)showFuelUplift2View:(id)sender { UIViewController *controller = [[UIViewController alloc] initWithNibName:@"FuelUplift2View" bundle:nil]; controller.title = @"Settings"; [self.navigationController pushViewController:controller animated:YES]; [controller release]; } And finally, my FuelUplift2ViewController.m, where the app crashes when trying to go back: - (IBAction)backFromFuelUplift2View { [self.navigationController popViewControllerAnimated:YES]; } I do not know if all this makes sense, I am currently beginning with my first application and am still learning thanks to the traditional trial an error method. Nevertheless, I cannot see the reason for this problem and would appreciate any help I can get. Thanks very much, Manu

• Using GraphicsServices.h/GSEvent as well as compiling CLI iPhone tools with XCode

  - by Peter Hajas

  I sent this to KennyTM (has all the private framework headers on GitHub) but I figured I'd ask here too just in case someone has some good ideas or any way to help me out. I'm trying to write a command line utility that sends GSEvents to operate the keyboard, touch/drag elements onscreen, and operate hardware buttons (volume, home, sleep, etc.) I grabbed the MouseSupport code and tried to look through it, but I couldn't find the easiest way to send GSEvents. I'm hoping someone here can help me. First, what's the simplest way to declare a GSEvent and send it? I looked at the iPhone development wiki, but the documentation was very vague. I understand that there's a purple event port (?) that I have to send these events to, but I don't understand how to do that. Could someone offer examples for, say, touching at a coordinate, typing a certain key, or pressing a hardware button? Also, do I have to write or do anything special if I want this utility to operate all applications as well as Springboard? I don't know if this is a special case because I want it at the OS level. Ideally, I would SSH into the phone, start the program, and it would send GSEvents that would be handled by whatever application was open. As far as compiling this code, is there any way to do so under XCode? I don't know what sort of project template I should use (if any) and this is throwing me off. I don't need "build and go" support, I'm more than happy to scp the program over to the phone. I understand that compiling the code is also feasible on the phone. I have all of the headers from the SDK on my phone along with iphone-gcc, but when compiling some test programs I still get errors about not finding mach headers and CoreFoundation. Is there an easier way to do this? Lastly, are there other guides or pieces of literature that anyone can point me towards for learning more about this? I'm excited to get into open iPhone development (I have experience with the official SDK, but I want to go deeper). Thanks for any and all help people can offer!

• Voice Recognition Connection problem

  - by user244190

  I,m trying to work through and test a Voice Recognition example based on the VoiceRecognition.java example at http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/app/VoiceRecognition.html but when click on the button to create the activity, I get a dialog that says Connection problem. My Manifest file is using the Internet Permission, and I understand it passes the to the Google Servers. Do I need to do anything else to use this. Code below UPDATE: Ok, I was able to replace my emulator image with one from HTC that appears to come with Google Voice Search, however now when I run from the emulator, i'm getting an Audio Problem message with Speak Again or Cancel buttons. It appears to make it back to the onActivityResult(), but the resultCode is 0.
