flex3 autoupdater error - apache-flex

Dear all, I am working on flex3 and want to update my application by flex3 autoupdate. When my installed application runs, my checkUpdate function calls the autoUpdater code. It starts but when it reaches to 100%, it shows this error: "There was an error downloading the update. Error# 16824"
My mxml code is here http://tinypaste.com/92138b and server xml code is here http://tinypaste.com/e3792
Please guide me.
Many Thanks

Google is your friend for this one; it looks like you forgot to update the application descriptor version number in the updated version on the interweb.

I was unable to see your code as our work router blocks tinypaste. That said, however, I can tell you that air updates done via the ApplicationUpdater class are all based upon the updater xml file that you create/copy-out-there, and the xml file used for the compiler that sets the filename, version, application ID, etc. (most of which is used for the exe-compiler/exe-wrapper that facilitates the "bridge" between the OS and your compiled actionscript code). This link, might help: dezeloper.wordpress.com.
All-in-all keep debugging. The ApplicationUpdater class is one that was relatively well-written and is pretty self-explainable... once you get past this bug, there are a couple more that might be a sync-the-xml-text pain-in-the-butt. For example... I can tell you that in AIR 1.0 (and this may still be true in recent releases) if you made a change to your application xml file, and you're compiling from eclipse/flexBuilder/flashBuilder, you had to "project > clean" for those xml options to get picked up.
Best of luck,
Jeremy

Qt Application throws an Access violation exception during startup

I have a Qt Application that works in Debug mode without any problems. Since two days I'm trying to make it work in Release mode. After some Project property modification I managed to compile without errors. But unfortunalty the application crashes before even reaching the main method.
That's my environment:
MS VS 2010
Qt 4.8.4
Qwt 6.0.0
I don't know if this is relevant, but I also installed the Qt plugin for VS and used Qt Designer to create my GUI.
As I said in Debug mode there is no problem. Starting the release version from the Visual Studio produces the following error:
Unhandled exception at 0x77c415de in Application.exe: 0xC0000005: Access violation reading location 0x0000000c.
The last function I can "debug" is the the "WinMain" method called inside the method "__declspec(noinline) int __tmainCRTStartup", which is located in crtexe.c (honestly I have no idea what this is). The call stack looks like this:
ntdll.dll!77c415de()
[Frames below may be incorrect and/or missing, no symbols loaded for ntdll.dll]
ntdll.dll!77c415de()
ntdll.dll!77c3014e()
msvcr100.dll!718f0269()
msvcr100.dll!718f233b()
msvcr100.dll!718f233b()
msvcr100.dll!718f233b()
QtCore4.dll!5b2cfc49()
QtGui4.dll!57bf54ea()
Application.exe!__tmainCRTStartup() Line 547 + 0x1c bytes C
kernel32.dll!754633aa()
ntdll.dll!77c59ef2()
ntdll.dll!77c59ec5()
In the moment I'm totaly lost with this problem. No idea what to try further...
I've tried to reduce the program and commented out the complete main function. But the result was the same behaviour. As I said the error occurs even before the main function is called. I also turned off all optimization and recompiled... didn't changed anything.
What completly puzzles me, is the fact that it "works" when I call "Application.exe" from the command prompt (ok it also crashes but much later during execution). Weird, isn't it? What is the difference between starting from command prompt and starting from Visual Studio application?
AnatolyS and npiau thanks for you tips. Meanwhile I continued digging in my code. More or less I started from the very beginning and finally got the place the error occurs. I suppose npiau is right, it has nothing to do with Qt.
It's still (for me) a strange problem. I posted it in a new thread (because it has little to do with this thread): C++ Creation of a Singleton object in initializer list causes an Access Violation (only Release Mode)
The problem is not in QT but in your source code. "0xC0000005: Access violation reading location 0x0000000c" means that you try to access a wrong memory location.
Check out your arrays, ans pointers.

Runtime error but project compiles fine - Imports/using missing

I am very confused right now. I have VS2008 at my job right now and I have a weird behavior that I have been searching for a while now.
When I compile the project, it works fine, but in runtime I have an error saying object not defined or something like that. The problem is that the imports/using is missing in my class but why does it compile?
In fact, I want to be able to see that error when compiling not when running the webapp.
REEDITED: Here is an example. Lets say i want to use a typed list, I am declaring my object list(of int) for example without having added my imports (system.collection.generic) in the class. then I compile, it works and then I run it, it fails because of the imports missing. is this normal behavior or not?
REREEDITED: I just noticed that the DLL of all my references were not copied in my bin folders even though all of them are set to "Copy local = true". Is it possible that it has to do with our shared directory (all external dlls) being on a network drive (\server\shared). I am really out of ideas on this issue....
problem was because we were having the classes in the app_data folder
The answer to the current question - why you are getting this error - is that ASP.NET does not show many errors at compile-time. You will need to manually go through the application to verify that all pages work correctly. This is very common with ASP.NET development, due to the nature of the environment.
If you post the real errors (probably should be as another SO question), we can perhaps help you with them.
Remove all the dll, etc from bin...
rebuild the whole solution then run
It should run fine...

Flex SDK missing fundamental things

alt text http://img710.imageshack.us/img710/4107/flashbuildershite.jpg
All of a sudden Flash Builder 4 is missing all kinds of fundamental things and is generating incorrect errors. I've had the same issue yesterday, where I fixed it by downloading a new Flex SDK and importing that into FB. I did this again, but this time it fixed nothing.
I don't think it's something I did, like removing critical references from the build path. The errors also appeared on projects I was not working on at the time. It occurs for ActionScript, Flex and Flex Library projects alike.
Update 3: Well, i've singled the problem down to a single piece of code, though a very simple one. I can make a new workspace in FB and things work ok, then screw the workspace up forever by adding this code to a project. All projects will have errors and closing or even removing the faulty project does not change this. Making another new workspace (without the faulty code) makes my projects compile again.
Link: http://www.the3rdage.net/files/2745/Main.as
(i've uploaded the file in case an odd character or encoding error causes the error)
Update 2: I've tried manual compiling with mxmlc, the same errors occur. It appears to be an SDK problem, not Flash Builder.
Update: I find this stack trace in the Flash Builder error log:
!ENTRY com.adobe.flexbuilder.project 4 43 2010-05-11 11:55:47.495

Did you get a chance to list this issue in their bugs list. I have not yet tried Flex 4. did you try to refresh your project and re open your flash builder.
Update:
What about a simple project. I think you are trying to load something which its not able to get.
mxmlc - verify-digests
Try this.
Problems I've had that were somewhat similar, once I had FB running under the wrong version of Java. Another time I had done some edits to the flex-config.xml file in order to make it work with a Maven plugin we had written in house. After that we made the plugin look at a copy of the original xml file, so that problem went away.
hth.
Might i recommend HFCD? The HellFire Compile Daemon is an out of process flex compiler that speeds up compile times immensely, and almost more importantly runs in a separate process from FlashBuidler. I have had some absolutely horrendous errors with Flash Builder due to the complexity and size of our project, where HFCD has helped tremendously here.

Selenium-Flex API sample problem

I'm trying the sample demo of selenium flex API. After following the instructions on the main page for compiling the project with sfpi.swc and taking the generated selben.swf in bin directory and trying to run some test(assertFlexText) using Selenium IDE, I get the following error:
[error] Function getFlexText not found on the External Interface for
the flash object selben
I have tried several other flex tests and got error messages similar to the one mentioned above.
For some reason I believe that the generated selben.swf through the automatic build of project in flex builder is not the desired one, though it didn't indicate any build problem after including sfpi.swc.
Any idea?
I use SeleniumFlex Api and SeleniumIde for my projecy with excellent result BUT using my own version of each of one. Your error maybe is for not include the lib of SeleniumFlexApi in the compile time( -include-libraries "libs\SeleniumFlexAPI.swc" ).
After that u can enable capture and replay with SeleniumIde change the main source (read this post) and use the user-extensions.js (in the SeleniumFlexApi project) with the SeleniumIde user option. Its really easy.
With these change u can capture and replay in firefox (v 3.06 or minor) and after that, if u use java, u can use Flex-UI-Selenium, Flash-Selenium for ur integration test with SeleniumRC.
I hope this information be usefull. I u have any question let me know.

How to debug a WER minidump of an "ngen"ed image

When ngen is executed on a .NET managed application at installation time, and a crash dump is retrieved from Windows Error Reporting for the app, how can you use it to see a stack trace, variables, etc.?
Here's some background related to the question: We have a .NET app that gets ngened at installation. When it crashes due to an unhandled .NET exception, the crash is bucketted in Windows Error Reporting, and from that I was able to download the minidump.mdmp file from winqual.microsoft.com.
I put minidump.mdmp in a folder containing the .dbg files for the build of the app that crashed, and double-clicked minidump.mdmp to open it in a new instance of VS2008 SP1. My stack trace looks like this:
kernel32.dll!RaiseException() + 0x3d bytes
mscorwks.dll!RaiseTheExceptionInternalOnly() + 0x295 bytes
mscorwks.dll!JIT_Throw() + 0x130 bytes
MyApp.ni.exe!000007feee74c84c()
[Frames below may be incorrect and/or missing, no symbols loaded for MyApp.ni.exe]
0000000070000d5e()
MyApp.ni.exe!000007feee611000()
000000000300bf78()
000000000300bf60()
The Modules window indicates that symbols are loaded for the OS and .NET DLLs, but for the application modules, I get this:
MyApp.exe -> No native symbols in symbol file.
MyApp.ni.exe -> No matching binary found.
MyAppsLibrary.ni.dll -> No matching binary found.
The easiest way to debug those dumps is with the Windows Debuggers (Windbg, cdb, or ntsd) and to load the SOS debugger extension (you can search for SOS for more details).
As far as I remember, the NGEN'ed part of thing shouldn't matter for SOS as long as you have the original EXE and the symbols (Since it's your app, I'd expect you have the non ngen'ed exe and symbols).
"Debugging Tools for Windows" (specifically, WinDBG) has limited support for managed apps. Provided with PDBs, you should be able to see the call stack, including source line references. To see variable values, you'll need to use the SOS plugin, which is more difficult that just opening the call stack window.
If you're able to request the clients to run your app again, ask them to run it with the following environment variable set: COMPLUS_ZapDisable=1
This way CLR won't load the native images when running your app and you'll see your usual modules with symbols on the stack.

Is this of any help for you:
Symbol issue when debugging C# code
The guy seems to be able to load some symbols to debug his application from the crash dump, had a problem loading the correct symbols but someone answered his question.
Since this is managed code, you may need to set the _NT_EXECUTABLE_IMAGE_PATH environment variable to point to the folders where your executables live. In this case, you'll need to locate the folder in the NativeImage cache that points to your assemblies. The debugger needs the images in order to load the assembly.
