Does anyone know of a flash projector 'project' or 'framework' that uses a new flashPlayer for each window?
We've used mProjector, which works well to a point, but I'm very disappointed in the fileIO patterns they use. It is very buggy with regard to reading and writing files.
mdm zinc uses multiple windows, but it is all sits on one flashPlayer 'session'. The same applies for AIR. It is great, but there isn't a way to make each window run on a seperate flashPlayer... extreme number crunching on one window will lock up all other windows.
Thank you in advance. --jeremy
edit - Just to clarify my needs (since I'm adding a little bounty), the app is an ERP application, built on Flex 3.x, and the size and scope of the project == huge.
tl;dr -- I need an exe wrapper (for windows), similar to AIR, that can have multiple windows, running each window on a seperate flashPlayer instance, and when a window is closed, it blows-away that flashPlayer instance / stage / etc.
How about a DotNet application to handle the wrapper? It can spawn windows each with it's own instance of the Flash Player (ActiveX dll) running in it.
I'm Sorry I found this too late to help you, but hopefully this saves someone else some work.
You can use SWF Studio to do this.
What you do is create a stub EXE that takes command line parameters to tell it which SWF to load. The parameter tells the EXE which SWF to load from its internal collection of files added to the SWF studio Files Tab. Whenever you need to open a new "window" you just execute your own EXE again and pass it the name of the SWF to use.
SWF Studio's App.sendData commands allows you to send data between youe various windows with very little effort so your separate applications can easily behave like they are all parts of a single application.

i am working on sample applications using QT on Mac and i found out problem with one of its API. I want to run process so i am using following function
QProcess::startDetached();
And i am passing program(location of exe )and argument list as parameter now problem is that if the application is allready running then the this will create another process and runs it where as when i cross cheked with Windows its behavior is different in the sense that it does not start application which is allready running. can anyone help me how to fix the issue??
I think, it depends on the application properties. On window you can open multiple Doc files but cannot open Window Media player in two different (new) window.
So, First try opening a new application while its running. If its success, then it should work with QProcess .
Problem background:
I have a Qt/QML Symbian application targeting Qt 4.7.4, that requires a QML Camera component. The current state of Camera component has a serious performance bug, where once initialized, in order to overlay the camera view on the screen, it forces the whole application to "raster" graphics system. Even when the camera element is closed and destroyed the application remains in raster graphics system, and the whole app takes a large performance hit, rendering it almost unusable (scrolling lists, navigating through pages... ). The problem is gone only after the application is closed and restarted again, which is not really helpful.
As it appears this will not be resolved any time soon (it is marked as resolved only for some small subset of devices, which I doubt as I have a fairly high-end symbian device that suffers the same bug), I have to look into alternatives and workarounds.
One plausible workaround idea I have is to create a separate application, one whose only job is to capture the required image, process it and then closes. Currently I can do this by externally calling the native device camera application, but this is not a viable production solution. The main application would then start this second external application and wait for the result.
The question: is this possible with Qt creator? Packaging two different applications, and deploying them with a single deployment unit, such that the user does not have a complicated installation procedure?
I would have liked to solve this problem with QtCreator a few months ago but I failed. I managed to package two different applications into a single sis file by studying the pkg file format and creating a pkg file containing both applications.
It is worth examining the pkg files generated by QMake for each application and studying the pkg file format.
It is possible to get QMake to generate the desired pkg file. See the documentation of variable DEPLOYMENT, especially the part where pkg_postrules is discussed.
You can add your signed SIS file to another package with this line in PKG:
#"sub.sis",(0x20000002)
I have to make an application that will do the following:
Open a video file embedded in the application
Open some pdf files, preferably embedded in the application, but if it will have to open externally, it's no problem.
Work in fullscreen on the user computer, with a minimum resolution of 1024x768. I'm thinking about a resolution of 1024x768, centered on a black background.
I was thinking of using Flash, but I don't have much experience, so if there is another easier IDE that creates a Flash application, I would prefer that.
So, if anyone knows any Flash component to do this, I'll be very thankful.
Creating a Flash CDROM takes a little bit of care, but from my experience it's well worth it. From your requirements, the Flash IDE is well up to the task. The common requirements are as follows:
Windows / Mac platform
Flash Projector file
Autorun file (For the Windows platform)
Net access or all local
If your client is happy with creating the CDROM just for Windows, there will be very few dramas - but if they want to create a Mac-friendly version, you can do that too and I will explain afterwards.
Your Flash should preferably be an .exe projector file - the reason for this is so that the Windows user can open your app without downloading a Flash player (If the client wants a CDROM, they probably have limited net access, so this is a good thing!)
Within Flash, you can perform all your standard fs commands including full-screen.
You will likely need an Autorun file so that the user sees your application as soon as you put in the CDROM - simply create a file named 'autorun.inf' in notepad and enter the following:
[autorun]
open=yourProjector.exe
Where 'yourProjector.exe' is the name and path of your projector file.
It sounds like you're going to embed your videos and content in the CDROM - this is usually the ideal case, since your client won't receive annoying security messages, but this can also be a bad thing if you want to correct your content later (spotting errors after a thousand CDROMS have been distributed can be a PAIN).
You can serve some of your content online to avoid this, but it would give your user some ugly messages, so as long as you triple-check your content and embed everything, it would be the best scenario.
Now for a Mac, Apple has done away with autorun features years ago - there is a way to turn it on through Quicktime, but this is off by default for almost all Mac users, and turning it on is not recommended because it makes the Mac vulnerable to the 'Hong Kong Virus', one of the few Mac viruses around.
You can make your CDROM mac-friendly by creating a Mac Projector and adding instructions for how to use it by changing the background image of the CDROM window. I haven't had to do it before, but I hear that it's not too difficult.
You can use the Flash Projector. Here is a tutorial to get you started. Now, you won't be able to embed the PDF files but you can open them easily enough using fscommand("exec","foo.pdf")
You can create an Adobe AIR Application; however it won't run off the CD ROM; it'll need to be installed locally.
If creating a projector from Flash Pro doesn't work; look at a tool like Janus or Zinc
I am looking for options to download, Install and run a custom plugin/add-on(an exe or an installer) from my Flash Movie similar to how the connectnow does that?
When we initiate the screen sharing for the first time, connectnow prompts us for mandatory add-in by showing the message "To use this application, you need the Adobe ConnectNow Add-in.Would you like to install it now?". Once we agree, it downloads and installs acaddin.exe at the location %USERPROFILE%\Application Data\Macromedia\Flash Player\www.macromedia.com\bin\acaddin on our local machine. Then automatically launches the acaddin.exe and allows the user to close the browser window from where the acaddin.exe was launched.
From the next time onwards, when we login to connectnow, it launches the exe directly.
In this context:
If I were to load my own exe/add-in from flash, How can I acheive that?
How does connectnow application/flash determine whether an add-in was already installed or not?
Connect, and I assume ConnectNow, use hidden, undocumented, private APIs for much of their functionality.
You will not be able to do this.
The best you can hope for is to pass the location of your executable to the browser as a local URL and let the browser handle it. I assume in most cases the browser will reject its' execution. Can you imagine the potential for abuse of such a feature?
Instead of using a browser based app, you may want to investigate using AIR and Native Process.
I just tried running a program that I've been developing with Qt outside of Qt. I double clicked on the program in /release, resolve all the missing DLLs, and find that my app has awful slow performance compared to when it is launched from within Qt Creator. What might be the reason for this?!
Well, I have never encountered this. Is there any files you are loading in your application which is big enough to make the application load slow? Like reading a big flat file and get the contents out of it. If so, just make sure that the file's contents hasn't changed while you were running through Qt Creator and when you run it outside. It's my guess though. For me, the performances doesn't have much differences in either cases.
