  • iPhone -trouble with a loading data from webservice into a tableview

    - by medampudi
    I am using a Window based application and then loading up my initial navigationview based controller. After loading it if the user is not registered/ does not have a credentials present then it takes the user to a login view controller . loginViewController *sampleView = [[loginViewController alloc] initWithNibName:@"loginViewController" bundle:nil]; [self.navigationController presentModalViewController:sampleView animated:YES]; [sampleView release]; then right after that i try to load the table with data that i get from a webservice using asiHTTP .. for this question lets say it takes 3 seconds time to get the data and then deserialize it . now... my question is it works out okey in the later runs as I store the username and password in a seure location... but in the first instance.... i am not able to get the data to laod to the tableview... I have tried a lot of things... 1. Initially the data fetch methods was in a diffrent methods.. so i thought that might be the problem as then moved it the same place as the tbleviewController(navigationController) 2. I event put in the Reload data at the end of the functionality for the data parsing and deserialization... nothing happens. 3. i did not understand the concept of @property and alll.... 4. The screen is black screen with nothing displayed on it for a good 5 seconds in the consecutive launches of the app.... so could we have something like a MBPorgressHUD implemented for the same. could any one please help for these scenarios and guidance as to what paths to take from here...

  • ApplicationDelegate is not doing its own job here ! Can anyone help me??

    - by ahmet732
    (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { MaSystemGuiAppDelegate *appDelegate = (MaSystemGuiAppDelegate *)[[UIApplication sharedApplication] delegate]; appDelegate.deneme = [tableData objectAtIndex:indexPath.row] ; NSLog(@"my row", appDelegate.deneme); // THIS IS NOT PRINTING NSLog(@"my row = %@", [tableData objectAtIndex:indexPath.row]); //THIS IS PRINTING THE VALUE ON CONSOLE NSInteger row = [indexPath row]; if(self.searchDetailViewController == nil){ SearchDetailViewController *asearchDetail = [[SearchDetailViewController alloc] initWithNibName:@"SearchDetailView" bundle:nil]; self.searchDetailViewController = asearchDetail; [asearchDetail release]; } searchDetailViewController.title = [NSString stringWithFormat:@"%@", [searchArray objectAtIndex:row]]; MaSystemGuiAppDelegate *delegate = [[UIApplication sharedApplication] delegate]; [delegate.searchNavController pushViewController:searchDetailViewController animated:YES]; } "deneme" is a NMUtableArray is identified in MaSystemGuiAppDelegate.h (I identified it as a variable and put its property there) and I wrote "deneme= [[NSMutableArray alloc]init]; in applicationDidFinishLaunching method in MaSystemGuiAppDelegate.m. In the code above, [tableData objectAtIndex:indexPath.row] is retrieving the one of the value touched on tableview. When I put that value in deneme (as u noticed in the code) it is printing nothing. What am i missing? (I imported MaSystemGuiAppDelegate.h)

  • folder structure in a mercurial repo?

    - by ajsie
    I have just switched from svn to mercurial and have read some tutorials about it. I've still got some confusions that i hope you could help me to sort out. I wonder if I have understood the folder structure in a mercurial repo right. In a svn repo I usually have these folders: svn: branches (branches/chat, branches/new_login etc) tags (version1.0, version2.0 etc) sandbox trunk Should a branch actually be another clone of the original/central repo in mercurial? it seemed like that when I read the manual. And a tag is just a named identifier, but you should clone the original/central repo whenever you want to create a tag? How about the sandbox? should that be another clone too? So basically you just have in a repo all the folders/files that you would have in the trunk folder? mercurial: central repo: projects folders/files (not in any parentfolder) tag repo: cloned from central repo at a given moment for release (version1.0, version2.0 etc) branch repo: cloned from central repo for adding features (chat, new_login etc) sandbox repo: experimental repo (could be pushed to central repo, or just deleted) is this correct?

  • Finding the width of a directed acyclic graph... with only the ability to find parents

    - by Platinum Azure
    Hi guys, I'm trying to find the width of a directed acyclic graph... as represented by an arbitrarily ordered list of nodes, without even an adjacency list. The graph/list is for a parallel GNU Make-like workflow manager that uses files as its criteria for execution order. Each node has a list of source files and target files. We have a hash table in place so that, given a file name, the node which produces it can be determined. In this way, we can figure out a node's parents by examining the nodes which generate each of its source files using this table. That is the ONLY ability I have at this point, without changing the code severely. The code has been in public use for a while, and the last thing we want to do is to change the structure significantly and have a bad release. And no, we don't have time to test rigorously (I am in an academic environment). Ideally we're hoping we can do this without doing anything more dangerous than adding fields to the node. I'll be posting a community-wiki answer outlining my current approach and its flaws. If anyone wants to edit that, or use it as a starting point, feel free. If there's anything I can do to clarify things, I can answer questions or post code if needed. Thanks! EDIT: For anyone who cares, this will be in C. Yes, I know my pseudocode is in some horribly botched Python look-alike. I'm sort of hoping the language doesn't really matter.

  • Model class for NSDictionary information with Lazy Loading

    - by samfu_1
    My application utilizes approx. 50+ .plists that are used as NSDictionaries. Several of my view controllers need access to the properties of the dictionaries, so instead of writing duplicate code to retrieve the .plist, convert the values to a dictionary, etc, each time I need the info, I thought a model class to hold the data and supply information would be appropriate. The application isn't very large, but it does handle a good deal of data. I'm not as skilled in writing model classes that conform to the MVC paradigm, and I'm looking for some strategies for this implementation that also supports lazy loading.. This model class should serve to supply data to any view controller that needs it and perform operations on the data (such as adding entries to dictionaries) when requested by the controller functions currently planned: returning the count on any dictionary adding one or more dictionaries together Currently, I have this method for supporting the count lookup for any dictionary. Would this be an example of lazy loading? -(NSInteger)countForDictionary: (NSString *)nameOfDictionary { NSBundle *bundle = [NSBundle mainBundle]; NSString *plistPath = [bundle pathForResource: nameOfDictionary ofType: @"plist"]; //load plist into dictionary NSMutableDictionary *dictionary = [[NSMutableDictionary alloc] initWithContentsOfFile: plistPath]; NSInteger count = [dictionary count] [dictionary release]; [return count] }

  • Stopping work from one thread using another thread

    - by 113483626144458436514
    Not sure if my title is worded well, but whatever :) I have two threads: the main thread with the work that needs to be done, and a worker thread that contains a form with a progress bar and a cancel button. In normal code, it would be the other way around, but I can't do that in this case. When the user clicks the cancel button, a prompt is displayed asking if he wants to really cancel the work. The problem is that work continues on the main thread. I can get the main thread to stop work and such, but I would like for it to stop doing work when he clicks "Yes" on the prompt. Example: // Main thread work starts here t1 = new Thread(new ThreadStart(progressForm_Start)); t1.Start(); // Working for (i = 0; i <= 10000; i++) { semaphore.WaitOne(); if (pBar.Running) bgworker_ProgressChanged(i); semaphore.Release(); if (pBar.IsCancelled) break; } t1.Abort(); // Main thread work ends here // Start progress bar form in another thread void progressForm_Start() { pBar.Status("Starting"); pBar.ShowDialog(); } I could theoretically include a prompt in the cancelWatch() function, but then I would have to do that everywhere I'm implementing this class.

  • Correct way to switch between UIView with ARC. My way leads to memory leaks :( (iOS)

    - by Andrei Golubev
    i use xcode 4.4 with ARC on.. I have dynamically created UIViews in the ViewController.m: UIView*myviews[10]; Then in the - (void)viewDidLoad function i fill each of it with pictures i need myviews[viewIndex] = [[UIView alloc]initWithFrame:myrec]; UIImage *testImg; UIImageView * testImgView; testImg = [UIImage imageNamed:[NSString stringWithFormat:@"imgarray%d.png", viewIndex]; testImgView.image = testImg; viewindex++; So all seems to be fine, when i want to jump from one view to another i do with two buttons next: [self.view addSubview:views[viewIndex]]; CATransition *animation = [CATransition animation]; [animation setDelegate:self]; [animation setDuration:1.0f]; [animation setType:@"rippleEffect"]; [animation setSubtype:kCATransitionFromTop]; //[animation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]]; [self.view.layer addAnimation:animation forKey:@"transitionViewAnimation"]; Nothing seems to be bad, but the memory consumption grows with huge speed when i switch between views.. and then i get low memory warning or sometimes application will just crash. I have tried to use UIViewController array and was switching between the controllers: nothing changes, the memory low warning is what i end up with.. Maybe i need to clean the memory somehow? But how? ARC does not allow to use release and so on.. last what i have tried (sorry, maybe not very professional) before to add new subview is this NSArray *viewsToRemove = [self.view subviews]; for (UIView *views in viewsToRemove) { [views removeFromSuperview]; } But this does not help either.. Please don't judge too strong, i am still new to iOS and Objective-c..

  • Knowing which annotation is selected and accessing properties of it.

    - by kevin Mendoza
    So far my program can display a database of custom annotation views. Eventually I want my program to be able to display extra information after a button on the annotation bubble is clicked. Each element in the database has a unique entry Number, so I thought it would be a good idea to add this entry number as a property of the custom annotation. The problem I am having is that after the button is clicked and the program switches to a new view I am unable to retrieve the entry number of the annotation I selected. Below is the code that assigns the entry Number property to the annotation: for (id mine in mines) { workingCoordinate.latitude = [[mine latitudeInitial] doubleValue]; workingCoordinate.longitude = [[mine longitudeInitial] doubleValue]; iProspectAnnotation *tempMine = [[iProspectAnnotation alloc] initWithCoordinate:workingCoordinate]; [tempMine setTitle:[mine mineName]]; [tempMine setAnnotationEntryNumber:[mine entryNumber]]; } [mines dealloc]; When the button on an annotation is selected, this is the code that initializes the new view: - (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control { mineInformationController *controller = [[mineInformationController alloc] initWithNibName:@"mineInformationController" bundle:nil]; controller.modalTransitionStyle = UIModalTransitionStyleCrossDissolve; [self presentModalViewController:controller animated:YES]; [controller release]; } and lastly is my attempt at retrieving the entryNumber property from the new view so that I can compare it to the mines database and retrieve more information on the array element. iProspectFresno_LiteAppDelegate *appDelegate = (iProspectFresno_LiteAppDelegate *)[[UIApplication sharedApplication] delegate]; NSMutableArray* mines = [[NSMutableArray alloc] initWithArray:(NSMutableArray *)appDelegate.mines]; for(id mine in mines) { if ([[mine entryNumber] isEqualToNumber: /*the entry Number of the selected annotation*/]) { /* display the information in the mine object */ } } So how do I access this entry number property in this new view controller?

  • Sql Server problems reading columns with a foreigh key

    - by illdev
    I have a weird situation, where simple queries seem to never finish for instance SELECT top 100 ArticleID FROM Article WHERE ProductGroupID=379114 returns immediately SELECT top 1000 ArticleID FROM Article WHERE ProductGroupID=379114 never returns SELECT ArticleID FROM Article WHERE ProductGroupID=379114 never returns SELECT top 1000 ArticleID FROM Article returns immediately by 'returning' I mean 'in query analyzer the green check mark appears and it says "Query executed successfully"'. I sometimes get the rows painted to the grid in qa, but still the query goes on waiting for my client to time out - 'sometimes': SELECT ProductGroupID AS Product23_1_, ArticleID AS ArticleID1_, ArticleID AS ArticleID18_0_, Inventory_Name AS Inventory3_18_0_, Inventory_UnitOfMeasure AS Inventory4_18_0_, BusinessKey AS Business5_18_0_, Name AS Name18_0_, ServesPeople AS ServesPe7_18_0_, InStock AS InStock18_0_, Description AS Descript9_18_0_, Description2 AS Descrip10_18_0_, TechnicalData AS Technic11_18_0_, IsDiscontinued AS IsDisco12_18_0_, Release AS Release18_0_, Classifications AS Classif14_18_0_, DistributorName AS Distrib15_18_0_, DistributorProductCode AS Distrib16_18_0_, Options AS Options18_0_, IsPromoted AS IsPromoted18_0_, IsBulkyFreight AS IsBulky19_18_0_, IsBackOrderOnly AS IsBackO20_18_0_, Price AS Price18_0_, Weight AS Weight18_0_, ProductGroupID AS Product23_18_0_, ConversationID AS Convers24_18_0_, DistributorID AS Distrib25_18_0_, type AS Type18_0_ FROM Article AS articles0_ WHERE (IsDiscontinued = '0') AND (ProductGroupID = 379121) shows this behavior.

  • CALayer Border is appearing above subview (Z-order related, I think)

    - by kurisukun
    I have searched but could not find the reason for this behavior. I have a UIButton whose image I am setting. Here is how the button should appear. Note that this is just a photoshop of the intended button design: Essentially, it is a square custom UIButton with a white border and a little surrounding shadow. In the upper right corner, there is a "X" mark, that will be added programmatically as a subview. Here is the screenshot of the button within the actual app. At this point, I have only added a shadow and the X mark as a subview: How, when I try to add the white border, here is what it looks like: It seems that the white border is appearing above the X mark sublayer. I don't know why. Here is the code that I am using: // selectedPhotoButton is the UIButton with UIImage set earlier // At this point, I am adding in the shadow [selectedPhotoButton layer] setShadowColor:[[UIColor lightGrayColor] CGColor]]; [[selectedPhotoButton layer] setShadowOffset: CGSizeMake(1.0f, 1.0f)]; [[selectedPhotoButton layer] setShadowRadius:0.5f]; [[selectedPhotoButton layer] setShadowOpacity:1.0f]; // Now add the white border [[selectedPhotoButton layer] setBorderColor:[[UIColor whiteColor] CGColor]]; [[selectedPhotoButton layer] setBorderWidth:2.0]; // Now add the X mark subview UIImage *deleteImage = [UIImage imageNamed:@"nocheck_photo.png"]; UIImageView *deleteMark = [[UIImageView alloc] initWithFrame:CGRectMake(53, -5, 27, 27)]; deleteMark.contentMode = UIViewContentModeScaleAspectFit; [deleteMark setImage:deleteImage]; [selectedPhotoButton addSubview:deleteMark]; [deleteMark release]; I don't understand why the border is appearing above the deleteMark subview. Is there any way to get the intended effect? Thank you!

  • Mulltiple configurations in Qt

    - by user360607
    Hi all! I'm new to Qt Creator and I have several questions regarding multiple build configurations. A side note: I have the QtCreator 1.3.1 installed on my Linux machine. I need to have two configurations in my Qt Creator project. The thing is that these aren't simply debug and release but are based on the target architecture - x86 or x64. I came across http://stackoverflow.com/questions/2259192/building-multiple-targets-in-qt-qmake and from that I went trying something like: Conf_x86 { TARGET = MyApp_x86 } Conf_x64 { TARGET = MyApp_x64 } This way however I don't seems to be able to use the Qt Creator IDE to build each of these separately (Build All, Rebuild All, etc. options from the IDE menu). Is there a way to achieve this - may be even show Conf_x86 and Conf_x64 as new build configurations in Qt Creator? One other thing the Qt I have is 64 bit so by default the target built using Qt Creator IDE will also be 64 bit. I noticed that the effective qmake call in the build step includes the following option '-spec linux-g++-64'. I also noticed that should I add '-spec linux-g++-32' in 'Additional arguments' it would override '-spec linux-g++-64' and the resulting target will be 32 bit. How can I achieve this by simply editing the contents of the .pro file? I saw that all these changes are initially saved in the .pro.user file but does doesn't suit me at all. I need to be able to make these configurations from the .pro file if possible. Any help will be appreciated. 10x in advance!

  • How do I resize table view after resizing it's footer?

    - by Pedro
    I have a UITableView with header & footer added with code following the pattern shown in Apple's recipes example so the code for the footer is... if (tableFooterView == nil) { [[NSBundle mainBundle] loadNibNamed:@"DetailFooterView" owner:self options:nil]; self.tableView.tableFooterView = tableFooterView; } The footer NIB contains nothing more than a UITextView & I set text & resize with... CGSize size = [footerText sizeWithFont:[footerTextView font] constrainedToSize:CGSizeMake(304.0, 500.0)]; CGRect frame = CGRectMake(8.0, 0.0, size.width, size.height + 24.0); footerTextView.frame = frame; footerTextView.text = footerText; [tableFooterView sizeToFit]; That all works however I can't get the UITableView to resize around the resized footer. If I set the original size of the footer for any possible text I have a big whitespace in most cases. If I set it smaller then I can push the view up to see the whole text but it bounces back on release. I've tried [[self view] sizeToFit]; but that doesn't work. Can anyone fill me in? Cheers & TIA, Pedro :)

  • How do I Order on common attribute of two models in the DB?

    - by Will
    If i have two tables Books, CDs with corresponding models. I want to display to the user a list of books and CDs. I also want to be able to sort this list on common attributes (release date, genre, price, etc.). I also have basic filtering on the common attributes. The list will be large so I will be using pagination in manage the load. items = [] items << CD.all(:limit => 20, :page => params[:page], :order => "genre ASC") items << Book.all(:limit => 20, :page => params[:page], :order => "genre ASC") re_sort(items,"genre ASC") Right now I am doing two queries concatenating them and then sorting them. This is very inefficient. Also this breaks down when I use paging and filtering. If I am on page 2 of how do I know what page of each table individual table I am really on? There is no way to determine this information without getting all items from each table. I have though that if I create a new Class called items that has a one to one relationship with either a Book or CD and do something like Item.all(:limit => 20, :page => params[:page], :include => [:books, :cds], :order => "genre ASC") However this gives back an ambiguous error. So can only be refined as Item.all(:limit => 20, :page => params[:page], :include => [:books, :cds], :order => "books.genre ASC") And does not interleave the books and CDs in a way that I want. Any suggestions.

  • Formatting data for printing automatically

    - by 0bytes
    I have a requirement to retrieve data, format it to mimic an old request format we've used for years and then send it via IP address to any of a number of printers. Gathering the data and selecting the printer is no problem. I need to format the output for the printer and I'm just not sure what's best. The requirement is that the end users not have any interaction with the print request that's generated; only the intended recipients of the request job will know of the printed (& in a future release e-mailed) request. We also a requirement for a future update that we will have to incorporate into this solution an option to change the config in the DB so that each recipient site can choose printing or e-mail notification so I expect that I'll need to keep the control in a console app or webservice. I have the data and I can send it to the printers or generate an HTML-formatted e-mail easily; I just need to format it for the autoprinting. I don't think SSRS will help because I don't know of a way to designate a printer when running a report. Thanks for all help & suggestions.

  • Dealing with Expression Blend's lack of support for C++/CLI projects

    - by Brian Ensink
    I have a WPF C# project that references a C++/CLI mixed mode project. I'm having trouble using the WPF project in Expression Blend 3. I'm new to Blend so perhaps this is obvious, but it won't display the xaml designer properly until it builds the project. In my case it complains that my custom commands are not "recognized or accessible" and the solution is to build the project in Blend. But I can't build the project because it references a C++/CLI mixed mode project which Blend won't load. The WPF project is pure C# it just happens to reference a C++/CLI mixed mode project but I'm not asking Blend to do anything with the mixed-mode assembly. How can I work around this problem? Edit: I was able to get it to build by removing the reference to the C++/CLI mixed mode project and replacing it with a reference to the actual assembly. However this is not ideal because in my past experience Visual Studio will not always be able to resolve the reference when switching between release and debug configurations.

  • Array passing between classes, gone?

    - by Kenneth
    Hey guys . i have two classes, SelectionScreenTable & GraphView. In the SelectionScreenTable class .h, i declared a NSMutableArray called usagedatas NSMutableArray *usagedatas; } @property (nonatomic, retain) NSMutableArray *usagedatas; In the SelectionScreenTable class.m i remembered to @synthesize. Later on, while processing my methods, i did a NSLog(@"usagedatas count:%i",usagedatas.count); to check whether it has value and it returned 1. so yeah its good up to this point. And in the -(void) dealloc , i remembered to released it . [usagedatas release]; So now comes ME trying to use it in another class. In GraphView.m i imported the "SelectionScreenTable.h". in the -(void)viewDidLoad i did SelectionScreenTable *UD = [SelectionScreenTable alloc]; NSLog(@"GraphView UD.usagedataas.count = :%i",UD.usagedatas.count); it returned 0. Any idea guys?

  • drawRect gets called on UIView subclass but not on UIViewController

    - by HotFudgeSunday
    My code is working so far but I had to create a Class for the UIView. This is a bit inconvenient because I need to interact with the ViewController too. BTW, I did try [self setNeedsDisplay] on the ViewDidLoad of the UIViewController subclass file but it didn't work. Here's the code, which works on UIView Subclass but doesn't get called on a UIViewController one: - (void)drawRect:(CGRect)rect { UIColor *currentColor = [UIColor redColor]; CGContextRef context = UIGraphicsGetCurrentContext(); someNum = 1; CGContextBeginPath(context); CGContextMoveToPoint(context, 30, 40); [self addDotImageX:30 andY:40]; CGContextSetLineWidth(context, 2); CGContextSetStrokeColorWithColor(context, currentColor.CGColor); CGContextStrokePath(context); } Any ideas on what to try? BTW, this is a TabBar App. I know those can somehow block the calls to drawRect. The Tabs where created programatically, not through a Nib. Eg: NSMutableArray *listOfViewControllers = [[NSMutableArray alloc] init]; UIViewController *vc; vc = [[Education alloc] init]; vc.title = @"Education"; [listOfViewControllers addObject:vc]; vc.tabBarItem.image = [UIImage imageNamed:@"info.png"]; [vc release]; I would appreciate any ideas. I've been through the answers on this site related to setNeedsDisplay not calling drawRect and haven't found an answer for my particular case. Thanks.

    Hi, i m starting a new project that would basically take input from user and save them to database among about 30 screens, and i would like to find a framework that will allow the maximum number of these features out of the box : .net c#. windows form. unit testing continuous integration logging screens with lists, combo boxes, text boxes, add, delete, save, cancel that are easy to update when you add a property to your classes or a field to your database. auto completion on controls to help user find its way use of an orm like nhibernate easy multithreading and display of wait screens for user easy undo redo tabbed child windows search forms ability to grant access to some functionnalities according to user profiles mvp/mvvm or whatever design patterns either some code generation from database to c# classe or generation of database schema from c# classes some kind of database versioning / upgrade to easily update database when i release patches to application once in production automatic control resizing code metrics analysis some code generator i can use against my entities that would generate some rough form i can rearrange after code documentation generator ... At this point i have 3 options : Build from scratch on top of clr :( Find functionnalities among several open source framework and use them as a stack for infrastucture Find a "software factory" I know its lot but i really would like to use existing code to build upon so i can focus on business rules. What open source tools would u use to achieve these ?

Here's my class: Mymic class: public class MyMic { MediaRecorder recorder2; File file; private Context c; public MyMic(Context context){ this.c=context; } private void stopRecord() throws IOException { recorder2.stop(); recorder2.reset(); recorder2.release(); } private void startRecord() { recorder2= new MediaRecorder(); recorder2.setAudioSource(MediaRecorder.AudioSource.MIC); recorder2.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP); recorder2.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB); recorder2.setOutputFile(file.getPath()); try { recorder2.prepare(); recorder2.start(); } catch (IllegalStateException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } } } my Receiver Class: public class MyReceiver extends BroadcastReceiver { private Context c; private MyMic myMic; @Override public void onReceive(Context context, Intent intent) { this.c=context; myMic = new MyMic(c); if(my condition = true){ myMic.startRecord(); }else myMic.stopRecord(); } } So when I'm calling startRecord() it create a new MediaRecorder but when i instantiate my class a second time i can't retrieve my Object. Can i retrieve my MediaRecorder with his addresse

  • How can I copy files in the middle of a build in Team System?

    - by Dana
    I have two solutions that I want to include in a build. Solution two requires the dll's from solution one to successfully build. Solution two has a Binaries folder where the dll's from solution one need to be copied before building Solution two. I've been trying an AfterBuild Target, hoping that it would copy the items after the first SolutionToBuild, but it doesn't fire then. I'm guessing that it would probably fire after both solutions have compiled, but that's not what I want. <SolutionToBuild Include="$(BuildProjectFolderPath)/../../Main/Framework.sln"> <Targets>AfterCompileFramework</Targets> <Properties></Properties> </SolutionToBuild> <SolutionToBuild Include="$(BuildProjectFolderPath)/../../../Dashboard/Main/Dashboard.sln"> <Targets></Targets> <Properties></Properties> </SolutionToBuild> <ItemGroup> <FrameworkBinaries Include="$(DropLocation)\$(BuildNumber)\Release\Framework.*.dll"/> </ItemGroup> <Message Text="FrameworkBinaries: @(FrameworkBinaries)" Importance="high"/> <Copy SourceFiles="@(FrameworkBinaries)" DestinationFolder="$(BuildProjectFolderPath)/../../../Dashboard/Main/Binaries"/>

  • Timing related crash when unloading a DLL?

    - by fbrereto
    I know I'm reaching for straws here, but this one is a mystery... any pointers or help would be most welcome, so I'm appealing to those more intelligent than I: We have a crash exhibited in our release binaries only. The crash takes place as the binary is bringing itself down and terminating sub-libraries upon which it depends. Its ability to be reproduced is dependent on the machine- some are 100% reliable in reproducing the crash, some don't exhibit the issue at all, and some are in between. The crash is deep within one of the sublibraries, and there is a good likelihood the stack is corrupt by the time the rubble can be brought into a debugger (MSVC 2008 SP1) to be examined. Running the binary under the debugger prevents the bug from happening, as does remote debugging, as does (of all things) connecting to the machine via VNC. We have tried to install the Microsoft Driver Development Kit, and doing so also squelches the bug. What would be the next best place to look? What tools would be best in this circumstance? Does it sound like a race condition, or something else?
