  • How to approach local database management via Flex/Air App

    - by Damon
    I am planning on using Flash Builder 4/Flex to write an AIR application which is primarily based around recording, storing and analyzing data. I'll be creating charts etc that need to update in almost real time. It's essential to me that the application be able to function without an internet connection so I need a local database of some variety, but I would also eventually like to build in online synchronization of the data where either database can be update each other based on newer information. Moreover, some type of encryption would definitely be welcome, and speed is a large concern With all that in mind, what is my best approach to try and avoid headaches down the road?

  • What should I consider when deploying a new web farm?

    - by tsilb
    My web app has been chugging along just great in Production for years with one App server and one Web server. Now we're moving to a multi-server environment with 2 App and 3 Web servers. I have enough time to make changes before the go-live. As a Developer, what considerations should I take into account from coding, deployment, and architectural/ecosystem management perspectives? Already on my list: Remove tight-coupling between servers Applicable files (i.e. downloadables) stored in IMAGE fields in SQL instead of files on app server Deployment: Take out node out of the farm at a time

  • How can we avoid packet missing in UDP Flex?

    - by Naveen kumar
    Hi all, I'm trying to send large files using UDP Adobe air to CPP. While transferring large files some packets are missing. How can I retrieve the missing packets data? I'm first of all connecting client(air) with server(cpp) using tcp. After connection establishment I'm starting file transfer. I am planning to get the file missing data using tcp and then resending the missing packets using tcp. Can anybody tell me how can i come to know which packets are missing while transferring. Thank you.

  • Edit PDF files dynamically from Flash or Flex

    - by TandemAdam
    I am planning to do a CD-ROM in either Flash or Flex, possibly using the Adobe AIR runtime. This CD interactive will have a bunch of forms on it for the user to fill out. After they fill in a form, they will have the option of saving or printing a PDF that is based on there information. I am trying to find a way of editing the content of the PDF in Flash, so when the user fills out the form, the application will fill in the PDF with there details from the form fields. Is this is possible? It would be great if there was some way of having template PDFs (either on the CD as there own files, or in a Flash library), then flash could come along and fill in the specific fields inside the PDF. Can Adobe AIR help me in any way here?

  • NSURLConnection request seems to disappear into thin air

    - by ibergmark
    Hi Everybody! I'm having trouble with a NSURLConnection request. My app calls a routine called sayHello to identify a user's device. This code works fine for all devices I've tested it on, but for some devices the request just seems to disappear into thin air with no errors or popups on the device. One specific device that fails is an iPod Touch 2G running OS 3.1.3. The app start's fine and doesn't crash, and none of my error popup messages are displayed. I just can't understand why my server never receives the request since the call to initWithRequest returns a pointer. Any help is much appreciated. Thanks. Here's the relevant header info: @interface Globals : NSObject { UserItem *userData; NSURLConnection *urlConnection; NSString *imageCacheLocation; NSOperationQueue *opQueue; } Here's the implementation of sayHello: - (void)sayHello:(BOOL)updateVisits; { NSString *updString; if (updateVisits) updString = @"Y"; else updString = @"N"; NSDictionary *dataDict = [[NSDictionary alloc] initWithObjectsAndKeys: [[UIDevice currentDevice] uniqueIdentifier], @"id", kProgVersion, @"pv", @"1", @"pr", userData.tagID, @"tg", updString, @"uv", nil]; NSString *urlString = [[NSString alloc] initWithString:kHelloURL]; urlConnection = [self localPOST:dataDict toUrl:urlString delegate:self]; [dataDict release]; [urlString release]; } - (NSURLConnection *)localPOST:(NSDictionary *)dictionary toUrl:(NSString *)urlString delegate:(id)delegate { NSString *myBounds = [[NSString alloc] initWithString:@"0xKmYbOuNdArY"]; NSMutableData *myPostData = [[NSMutableData alloc] initWithCapacity:10]; NSArray *formKeys = [dictionary allKeys]; for (int i = 0; i < [formKeys count]; i++) { [myPostData appendData:[[NSString stringWithFormat:@"--%@\n", myBounds] dataUsingEncoding:NSUTF8StringEncoding]]; [myPostData appendData:[[NSString stringWithFormat: @"Content-Disposition: form-data; name=\"%@\"\n\n%@\n", [formKeys objectAtIndex:i], [dictionary valueForKey:[formKeys objectAtIndex:i]]] dataUsingEncoding:NSUTF8StringEncoding]]; } [myPostData appendData:[[NSString stringWithFormat:@"--%@--\n", myBounds] dataUsingEncoding:NSUTF8StringEncoding]]; NSURL *myURL = [[NSURL alloc] initWithString:urlString]; NSMutableURLRequest *myRequest = [[NSMutableURLRequest alloc] initWithURL:myURL cachePolicy:NSURLRequestReloadIgnoringCacheData timeoutInterval:30]; NSString *myContent = [[NSString alloc] initWithFormat: @"multipart/form-data; boundary=%@", myBounds]; [myRequest setValue:myContent forHTTPHeaderField:@"Content-Type"]; [myRequest setHTTPMethod:@"POST"]; [myRequest setHTTPBody:myPostData]; NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:myRequest delegate:delegate]; if (!connection) { [[Globals sharedGlobals] showAlertWithTitle: NSLocalizedString( @"Connection failed", @"alert title - connection failed") message: NSLocalizedString( @"Could not open a connection.", @"alert message - connection failed")]; } [myBounds release]; [myPostData release]; [myURL release]; [myRequest release]; [myContent release]; return connection; } - (void)handleNetworkError:(NSError *)error { if (networkErrorAlert) return; networkErrorAlert = YES; [[Globals sharedGlobals] showAlertWithTitle: NSLocalizedString( @"Network error", @"alert title - network error") message: [NSString stringWithFormat: NSLocalizedString( @"This app needs a network connection to function properly.", @"alert message - network error")] otherButtons:nil delegate:self]; } - (void) connectionDidFinishLoading:(NSURLConnection *)connection { [urlConnection release]; urlConnection = nil; } - (void) connection:(NSURLConnection *)connection didFailWithError:(NSError *)error { [self handleNetworkError:error]; [urlConnection release]; urlConnection = nil; }

  • Modularity in Flex

    - by Fernando
    I'm working on a pretty big application for Flex/Air. We are using GraniteDS and Tide to interact with the model from our Java EE server. I've been reading about modularization and Modules in Flex. The application has already been built, and I'm figuring a way out to re-design some classes and parts. From what I've read so far, I understand a Module is a different swf which can be dynamically load. Most of the tutorials/documentation are oriented to Flash "programmers" who are using Flex or Air instead of real developers, so that makes online resources harder to get. What I can't understand - yet - is how to encapsulate ActionScript classes or MXML views under this module. I've separated some of the code into libraries. For example, the generated code from Granite is in a "server" library. But I would like to separate parts of the logic with its Moderators, Controllers and Views. Are modules the way to go? Is there a "modules for dummies" or "head first Flex Modules for programmers" like tutorial in order to get a better perspective in order to build my architecture? When to choose libraries and when to choose modules? I'm using Flex 3.5, and a migration to Flex 4 is way far into the future, so no Flex 4 answers please, thanks!

  • how to keep a nativewindow on top

    - by Freddy Rios
    I need to keep a NativeWindow I am creating on top of the main window of the application. Currently I am using alwaysInFront = true, which is not limited to the windows in the application. I can successfully synchronize the minimize/restore/move/resize actions, so the top window behaves appropriately in those cases. Even though using this option has the drawback that if I alt-tab to other application the window goes on top of the other application. Because of the above I am trying to get it to work without using the alwaysInFront. I have tried using orderInFrontOf and orderToFront, which gets it in place but when I click an area in the main window the top one becomes hidden i.e. air makes it the top one. I have tried capturing activate/deactivate events but it only happens on the first click, so on the second click the top window becomes hidden again. I also tried making the top window active when the main one becomes active, but that causes the main one to loose focus and I can't click on anything. Ps. I am doing this to improve the behavior of a HTMLOverlay I am using - see http://stackoverflow.com/questions/1044927/flex-air-htmlloader-blank-pop-up-window-when-flash-content-is-loaded/1077738#1077738

  • iPhone static library Clang/LLVM error: non_lazy_symbol_pointers

    - by Bekenn
    After several hours of experimentation, I've managed to reduce the problem to the following example (C++): extern "C" void foo(); struct test { ~test() { } }; void doTest() { test t; // 1 foo(); // 2 } This is being compiled for iOS devices in XCode 4.2, using the provided Clang compiler (Apple LLVM compiler 3.0) and the iOS 5.0 SDK. The project is configured as a Cocoa Touch Static Library, and "Enable Linking With Shared Libraries" is set to No because I'm building an AIR native extension. The function foo is defined in another external library. (In my actual project, this would be any of the C API functions defined by Adobe for use in AIR native extensions.) When attempting to compile this code, I get back the error: FATAL:incompatible feature used: section type non_lazy_symbol_pointers (must specify "-dynamic" to be used) clang: error: assembler command failed with exit code 1 (use -v to see invocation) The error goes away if I comment out either of the lines marked 1 or 2 above, or if I change the build setting "Enable Linking With Shared Libraries" to Yes. (However, if I change the build setting, then I get multiple ld warning: unexpected srelocation type 9 warnings when linking the library into the final project, and the application crashes when running on the device.) The build error also goes away if I remove the destructor from test. So: Is this a bug in Clang? Am I missing some all-important and undocumented build setting? The interaction between an externally-provided function and a struct with a destructor is very peculiar, to say the least.

  • How can you start a process from asp.net without interfering with the website?

    - by Sem Dendoncker
    Hi, We have an asp.net application that is able to create .air files. To do this we use the following code: System.Diagnostics.Process process = new System.Diagnostics.Process(); //process.StartInfo.FileName = strBatchFile; if (File.Exists(@"C:\Program Files\Java\jre6\bin\java.exe")) { process.StartInfo.FileName = @"C:\Program Files\Java\jre6\bin\java.exe"; } else { process.StartInfo.FileName = @"C:\Program Files (x86)\Java\jre6\bin\java.exe"; } process.StartInfo.Arguments = GetArguments(); process.StartInfo.RedirectStandardOutput = true; process.StartInfo.RedirectStandardError = true; process.StartInfo.UseShellExecute = false; process.PriorityClass = ProcessPriorityClass.Idle; process.Start(); string strOutput = process.StandardOutput.ReadToEnd(); string strError = process.StandardError.ReadToEnd(); HttpContext.Current.Response.Write(strOutput + "<p>" + strError + "</p>"); process.WaitForExit(); Well the problem now is that sometimes the cpu of the server is reaching 100% causing the application to run very slow and even lose sessions (we think this is the problem). Is there any other solution on how to generate air files or run an external process without interfering with the asp.net application? Cheers, M.

  • Cross-platform HTML application options

    - by Charles
    I'd like to develop a stand-alone desktop application targeting Windows (XP through 7) and Mac (Tiger through Snow Leopard), and if possible iPhone and Android. In order to make it all work with as much common code as possible (and because it's the only thing I'm good at), I'd like to handle the main logic with HTML and JS. Using Adobe AIR is a possibility. And I think I can do this with various application wrappers, using .NET for Windows XP, Objective C for iPhone, Java for Android and native "widget" platform support for Mac and Windows Vista & 7 (though I'd like to keep the widget in the foreground, so the Mac dashboard isn't ideal). Does anyone have any suggestions on where to start? The two sticking points are: I'll certainly need some form of persistent storage (cookies perhaps) to keep state between sessions I'll also probably need access to remote data files, so if I use AJAX and the hosting HTML file resides on the device, it will need to be able to do cross-domain requests. I've done this on the iPhone without any problems, but I'd be surprised if this were possible on other platforms. For me, Android and iPhone will be the easiest to handle, and it looks like I can use Adobe AIR to handle the rest. But I wanted to know if there are any other alternatives. Does anyone have any suggesions?

  • Embedding binary video data in a swf file

    - by aaaidan
    Is it possible to play video from data that has been embedded in a swf at compile time (with the [Embed] metatag)? The "Import Video-Embed" feature provided by Flash CS3 etc. is not acceptable because it has many severe limitations (including sound synchronization issues, a maximum number of frames, and other caveats) I'm interested in being able to bundle flv video data in a swf (along with other assets), which will be played by an AIR application. I don't think it can be done. Anyone disagree?

  • How can I have an mx:Window automatically resize to its content?

    - by Troy Gilbert
    I'm creating windows in a Flex application (AIR) using the mx:Window component. I'd like the window to be automatically sized to its content (because it will be dynamic), in the same way that an mx:Panel or mx:Box would be. I've customized components before, so I'm somewhat familiar with the UIComponent lifecycle, but I'm not quite sure how best to do the logic for auto-sizing a container. If it makes it easier, I'm not expecting that the window auto-size to its content at any time, thought that would be a bonus!

  • Smallest executable for Windows

    - by Andrew Warren
    Hi I need to create a very simple GUI application for Windows(open a file, do some changes based on user input, upload the file to an intranet server). The client company has the latest release versions of Java SE, .NET and Adobe AIR installed on all their machines. And their #1 requirement is to have the smallest possible package for xcopy deployment. So which of the 3 listed platforms should I use? Another option of course is a native exe. Thanks, Andrew

  • Creating custom taskbar icon in Flex application

    - by steve_c
    I'm trying to create custom icons for my taskbar/desktop icons in my Flex WindowedApplication. So far, I've edited my -app.xml file to include the following: icons/t_16.png icons/t_32.png icons/t_48.png icons/t_128.png When the application is run, however, the default flex/air icon is still showing. I have my systemChrome set to standard, and transparent to false, not that they have any relevance to this. Any ideas?
