• Automate Google Chrome extension installation

  - by gtaborga

  Hi everyone, I am working on creating a Google Chrome extension. We have it included in an automated build system and since it is constantly being worked on we need a solution to be able to package the extension as a .crx file which according to http://code.google.com/chrome/extensions/packaging.html can easily be scripted. My question is after packaging the extension is there a known method either through the command-line or some other programmatic way, to install the newly packaged extension in an automated manner? If someone knows how or has any reference material that I can be pointed towards I would greatly appreciate any help that is offered. Thank you.

• [C#] Is variable assignment and reading atomic operation (threading)

  - by AStrangerGuy

  I was unable to find any reference to this in the documentations... Is assigning to a double (or any other simple type, including boolean) an atomic operation viewed from the perspective of threads? double value = 0; public void First() { while(true) { value = (new Random()).NextDouble(); } } public void Second() { while(true) { Console.WriteLine(value); } } In this code sample, first method is called in one thread, and the second in another. Can the second method get a messed up value if it gets its execution during assignment to the variable in another thread? I don't care if I recieve the old value, it's only important to receive a valid value (not one where 2 out of 8 bytes are set). I know it's a stupid question, but I want to be sure, cause I don't know how CLR actually sets the variables. Thanks

• networkActivityIndicatorVisible on iOS 4

  - by user365660

  Hi, I just downloaded xcode 3.2.3 (seperate directory installation) and ios 4 to my iphone. I'm having a problem with networkActivityIndicatorVisible. This works on 3.1.3, both phone and simulator. My code is (void)viewWillAppear:(BOOL)animated { [super viewWillAppear:animated]; UIApplication* app2 = [UIApplication sharedApplication]; app2.networkActivityIndicatorVisible = YES; [self loadSources]; // Loads data in table view app2.networkActivityIndicatorVisible = NO; } I get the same effect in the simulator and on the phone both with ios 4.o The networkActivity indicator becomes visible for a fraction of a second and then invisible and this is done after loading the data for the tableView. Has something changed with this? Teo

• Using PDF in iPad

  - by RVN

  Has Anyone tried using PDF in iPad Application, using CGPDf functions. I have used this in iPhone and it works perfectly , but when i use the same code in iPad , the Page are Shrunk in size, after a try outs i set the Scale as follows CGContextScaleCTM(context,1.85, -1.80); This time the it fits the screen perfectly , but that was just a trial and error , why does it not fit the screen as in iPhone, i have set the view size correctly too. Anyone having a clue about it please let me know. and also this is my drawRect method where i am drawing the PDF page void drawRect:(CGRect)rect{ UIGraphicsBeginPDFPage(); CGContextRef context = UIGraphicsGetCurrentContext(); CGPDFPageRef page = CGPDFDocumentGetPage(pdf, pageNumber); CGContextSaveGState(context); CGContextTranslateCTM(context, 1.0, self.frame.size.height); CGContextScaleCTM(context,1.0, -1.0); CGContextDrawPDFPage(context, page); CGContextRestoreGState(context); } Thanks

• Popover with embedded navigation controller doesn't respect size on back nav

  - by quixoto

  I have a UIPopoverController hosting a UINavigationController, which contains a small hierarchy of view controllers. I followed the docs and for each view controller, I set the view's popover-context size like so: [self setContentSizeForViewInPopover:CGSizeMake(320, 500)]; (size different for each controller) This works as expected as I navigate forward in the hierarchy-- the popover automatically animates size changes to correspond to the pushed controller. However, when I navigate "Back" through the view stack via the navigation bar's Back button, the popover doesn't change size-- it remains as large as the deepest view reached. This seems broken to me; I'd expect the popover to respect the sizes that are set up as it pops through the view stack. Am I missing something? Thanks.

• Sub-classing TreeView in C# WinForms for mouse over tool tips

  - by Matt

  Ok, this is a weird one. The expected behaviour for a TreeView control is that, if ShowNodeToolTips is set to false, then, when a label for a tree node exceeds the width of the control (or, more accurately, it's right hand edge is past the right hand edge of the client area), then a tooltip is shown above the node showing the full item's text. I'd like to disable that, because the above semantic doesn't always work, depending on what the treeview is contained within. So I have rolled my own, and got the tooltips to work (and line up better than the default one!) - but I would like to be able to disable the 'default' behaviour for situations where it would work natively. So, can anyone point me in the right direction as to which message to post to the TreeView in order to disable that behaviour? I have looked at the windows control reference, but couldn't find anything that looked like it might be the one. Thanks Matt

• Debugging FLEX/AS3 memory leaks

  - by Scott Evernden

  I have a pretty big Flex & Papervision3D application that creates and destroys objects continually. It also loads and unloads SWF resource files too. While it's running the SWF slowly consumes memory til about 2GB when it croaks the player. Obviously I am pretty sure I let go of reference to instances I no longer want with expectation the GC will do its job. But I am having a heck of a time figuring out where the problem lies. I've tried using the profiler and its options for capturing memory snapshots, etc - but my problem remains evasive. I think there are known problems using debug Flash player also? But I get no joy using the release version either. How do you go about tracking down memory leak problems using FLEX/AS3 ? What are some strategies, tricks, or tools you have used to locate consumption

• Classic ASP METADATA Tags Not Working - MDAC 2.8/WDAC 6.0 on a Windows 2008 Box Running IIS 7

  - by ajdams

  What I am trying to do is simple. I have some Classic ASP with include headers like the following referencing MDAC 2.5: METADATA TYPE="TypeLib" NAME="Microsoft ActiveX Data Objects 2.5 Library" UUID="{00000205-0000-0010-8000-00AA006D2EA4}" VERSION="2.5" Now I am trying to call this same include file on a Windows 2008 box with IIS 7 using MDAC 2.8 with this: METADATA TYPE="typelib" NAME="Microsoft ActiveX Data Objects 2.8 Library" UUID="{2A75196C-D9EB-4129-B803-931327F72D5C}" VERSION="2.8" My question is, why does this not work anymore? Has the tag reference changed? I ran MDAC checker and everything is installed correctly. What am I missing? I am running on a Windows 2008 box with IIS 7. Thanks in advance!

• Loose coupling of COM in C# or How to avoid COMException 0x80040154

  - by user283318

  I have a .Net 2 C# application I am developing which uses a VB 6 generated COM DLL. The VB DLL is updated frequently any my application crashes with a System.Runtime.InteropServices.COMException (0x80040154). The part of the COM DLL I use does not change but the version (and CLSID) will. The "Specific Version" option for the reference is false. The WrapperTool is tlbimp. How do I tell my application not to worry about changes in the DLL? Is there any way of checking just the functions I am using?

• How to refactor large projects in visual studio

  - by Aaron

  I always run into a problem where my projects in Visual Studio (2008) become huge monstrosities and everything is generally thrown into a Web Application project. I know from checking out some open source stuff that they tend to have multiple projects within a solution, each with their own responsibilities. Does anyone have any advice for how to refactor this out? What should be in a separate project vs. part of the web project? Can you point me to any reference materials on the subject, or is it just something you become accustomed to with time?

• Recommendations on resolving a cs1705 error

  - by Scott A. Lawrence

  I'm upgrading a number of solutions from Visual Studio 2008 to Visual Studio 2010RC. In the process of doing this, I've encountered two instances of compiler error cs1705, one for System.Core and another for System.Data.Linq. In each case, an assembly compiled earlier has a reference to the .NET 4.0 version of these system assemblies, while the web project I'm trying to compile only has references to the .NET 3.5 version of them. Adding .NET 4.0 versions of System.Core and System.Data.Linq to the web project doesn't resolve the error. Removing the .NET 3.5 versions of the assemblies so that only the .NET 4.0 versions remain results in even more errors. Any recommendations on how to resolve this error would be greatly appreciated.

• How to intercept UIScrollView contentOffset changes from UITableView subclass?

  - by mystify

  Actually, a UITableView is a UIScrollView (inherits from that). Now, I made a UITableView subclass and added this line of code to it: - (void)scrollViewDidScroll:(UIScrollView *)scrollView { NSLog(@"contentOffset: %@", NSStringFromCGPoint(self.contentOffset)); } For some reason this is never called when I scroll the table view. But since UITableView has a delegate property on it's own, I assume that it must implement UIScrollViewDelegate protocol and is the delegate for the scroll view itself. Isn't it? How could I intercept scroll position changes? I want to read them only. Probably I couldn't set them with contentOffset, right?

• How do I replace a modal view controller?

  - by Theory

  I'm using a modal view controller to allow a user to select an address book entry and email address. The ABPeoplePickerNavigationController object is displayed via presentModalViewController:animated: [self presentModalViewController:picker animated:YES]; What I want to do is keep the modal dialog up, but when the user selects the email address, it should cross-fade to a different controller that displays a message composition window. I've tried various approaches in peoplePickerNavigationController:shouldContinueAfterSelectingPerson:property:identifier: to dismiss the picker and set my custom composition controller as the modal view. I can do it any number of ways, but never does it fade smoothly from the picker to the composition controller -- unless I make the composition controller a modal dialog of the picker, in which case the picker re-appears when I dismiss the composition controller. I don't want that, either. There must be some way to smoothly replace one controller and its view with another controller and its view, all within the context of a modal dialog, and preferably with a cross fade. Suggestions greatly appreciated.

• Import AppleScript methods in another AppleScript?

  - by DASKAjA

  Is there a way to use defined AppleScript methods in other AppleScripts which reference the original AppleScript with something similar to import (f.e. in PHP)? I wrote a methode to set Skype status and mood-text: on setSkypeStatus(status, mood_text) tell application "System Events" set skypeRunning to count (every process whose name is "Skype") if skypeRunning > 0 then --only set status if skype is running tell application "Skype" set myStatus to "SET USERSTATUS " & status set myMood to "SET PROFILE MOOD_TEXT " & mood_text send command myStatus script name "AppleScript" send command myMood script name "AppleScript" return skypeRunning end tell else return skypeRunning end if end tell end setSkypeStatus now I'm searching for something like import skype_methods.scpt. Is there such a functionality. I can't something related with Google.

• New Facebook FQL table vs. Grap API

  - by PanosJee

  Hello everyone I just read the new User fql table fields at http://developers.facebook.com/docs/reference/fql/user As I can see a lot of the fields have been deprecated such as work_history or books and movies. It is quite essential for my app to get all those fields for my user's friends in a single fql query. If i am not wrong the only way to do this is to get those extra fields using the Graph API by requesting them seperately for every friend of my user. Is there any way to do it in a more efficient way without so many calls? Can I subscribe to real time updates for the request fields for my user's friends (i do not care about the logged in user data)? Thank you a lot

• ipad SplitView Orientation in DetailView

  - by nishantcm

  I am using this code in the DetailView.m of a splitview app. Now the orientation changes occur only when the device is rotated. The detection does not take place when the app is launched. I also get this warning warning: 'RootViewController' may not respond to '-adjustViewsForOrientation:' What change do I need to make the app adjust the orientation code when the app is launched. (void) willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration { [self adjustViewsForOrientation:toInterfaceOrientation]; } (void) adjustViewsForOrientation:(UIInterfaceOrientation)orientation { if (orientation == UIInterfaceOrientationLandscapeLeft || orientation == UIInterfaceOrientationLandscapeRight) { detailDescriptionLabel.center = CGPointMake(235.0f, 42.0f); bigthumbImageView.center = CGPointMake(355.0f, 70.0f); } else if (orientation == UIInterfaceOrientationPortrait || orientation == UIInterfaceOrientationPortraitUpsideDown) { detailDescriptionLabel.center = CGPointMake(160.0f, 52.0f); bigthumbImageView.center = CGPointMake(275.0f, 80.0f); } }

• Updating multiple Sprites - AS3 performance best practices

  - by dani

  Within the container "BubbleContainer" I have multiple "Bubble sprites". Each bubble's graphics object (a circle) is updated on a timer event. Let's say I have 50 Bubble sprites and each circle's radius should be updated with a mathematical formula. How do I organize this logic? How do I update all Bubble sprites within the BubbleContainer? (should I call a bubble.update() function or make a temporary reference to the graphics object?) Where do I put the Math logic? (as static functions?)

• ClickOnce and mageUI adding custom file folder problems

  - by Leszek Wachowicz

  What I do: Publishing .Net 3.5 application via VS, or msbuild (whatever), and now I need to insert to the published application separate directory (Modules - not added as a reference to the project - our project architecture does not allow this). So I'm copying the folder to published location then runs mageUI.exe select the application manifest and then the problems starts. As I press the populate button it's adding also hidden directory? So I remove the directory, after I want to save the manifest file I get the "Warning MSB3110: Assembly 'NAME.Shell.application.deploy' has mismatched identity 'NAME.Shell.application', expected file name: 'NAME.Shell.application.application'". Did you have the same problems, according to http://smartclient.codeplex.com/Project/Download/FileDownload.aspx?DownloadId=5060 it should be easy as 1-2-3 but it's not.

• Good embedded database solution (like SQLite) for .Net

  - by vfilby

  I am looking for file based storage solutions that I can use with a .Net project. THey need to have a sql-like interface for storing and retrieving data. They need to have relatively little overhead and must not require any additional components installed by the end user. I am hopping for a .dll that I can reference and use. Cool points awarded if it is closely tied to an ORM. My current favourite is SQLite, are there any better ones out there that I should know about? I have a (health?) bias against access because I feel it is overcomplicated for what I need, I am open to being convinced otherwise though. PS: "No, there is nothing better than SQLite" is a perfectly good answer.

• How to detect touches on MPMoviePlayerController window and still having the standard playback cont

  - by gkedmi

  Hello I have the MPMoviePlayerController set up to play a movie.I want to detect a touch on the movie for bringing up few buttons.I used the code : // The movie's window is the one that is active UIWindow* moviePlayerWindow = [[UIApplication sharedApplication] keyWindow]; // Now we create an invisible control with the same size as the window UIControl* overlay = [[[UIControl alloc] initWithFrame:moviePlayerWindow.frame]autorelease]; // We want to get notified whenever the overlay control is touched [overlay addTarget:self action:@selector(movieWindowTouched:) forControlEvents:UIControlEventTouchDown]; // Add the overlay to the window's subviews [moviePlayerWindow addSubview:overlay]; but then the play back controllers doesn't appear , I guess because the player window doesn't get the touch.how can I keep the player controllers and still detects touches? thanks

• UIScrollView setZoomScale not working ?

  - by iFloh

  Hi, I am struggeling with my UIScrollview to get it to zoom-in the underlying UIImageView. In my view controller I set - (UIView *)viewForZoomingInScrollView:(UIScrollView *)scrollView { return myImageView; } In the viewDidLoad method I try to set the zoomScale to 2 as follows (note the UIImageView and Image is set in Interface Builder): - (void)viewDidLoad { [super viewDidLoad]; myScrollView.contentSize = CGSizeMake(myImageView.frame.size.width, myImageView.frame.size.height); myScrollView.contentOffset = CGPointMake(941.0, 990.0); myScrollView.minimumZoomScale = 0.1; myScrollView.maximumZoomScale = 10.0; myScrollView.zoomScale = 0.7; myScrollView.clipsToBounds = YES; myScrollView.delegate = self; NSLog(@"zoomScale: %.1f, minZoolScale: %.3f", myScrollView.zoomScale, myScrollView.minimumZoomScale); } I tried a few variations of this, but the NSLog always shows a zoomScale of 1.0. Any ideas where I screw this one up?
