quick question, I've been looking for a simple logging tool for AS3 projects (I do not want any Flex dependencies) and my impression so far has been that there is no actively developed project.
What I need is basic logging, and adapters to allow me to send logging to file (using AIR and a LocalConnection maybe) and maybe send to html div etc.
Anyone have any opinions on a simple, light weight project?
We have recently started a project called AS3Commons that contains an early implementation of an AS3 Logging framework. We're aiming to provide a Logging abstraction API that allows you to plug in adapters for other logging frameworks. We also have a built-in logger that logs using trace.
It's usage is similar to other logging frameworks.
private static var logger:ILogger = LoggerFactory.getLogger("com.domain.Class");
Check it at http://code.google.com/p/as3-commons/
Any feedback is appreciated.
This is the best as3 logger by far!!!!

There is a standard Logging API in AS3. You can set it up to log to different targets. For instance, if you're using AIR, you could get it to log to a file using the FileTarget in as3corelib.
Setting up:
var logFile:File = File.applicationStorageDirectory.resolvePath("logs/logfile.log");
var logTarget:FileTarget = new FileTarget(logFile);
logTarget.filters = ["path.to.Class"];
logTarget.level = LogEventLevel.ALL;
logTarget.includeDate = true;
logTarget.includeTime = true;
logTarget.includeCategory = true;
logTarget.includeLevel = true;
Log.addTarget(logTarget);
Logging:
var log:ILogger = Log.getLogger("path.to.Class");
log.info("testing the logging...");
I'm always surprised at the number of people who haven't heard of Arthropod. It does everything you described and more. Including password encrypted connections. Arthropod is also set up in a way that it is very easy to make quick edits to the class for your specific needs.
I've got a Flash-friendly logging project going. It's nothing big (yet?) but it's light and handy. It does (optionally) take advantage of Arthropod (a great project) but you can pretty easily shoot the output anywhere you like. It works similarly to the Flex framework so if you are familiar with that then the transition would be painless.
You can read about the project and download the goods here.
MonsterDebugger has more options than it sounds like you're looking for. But it is small and has some very handy features. Including instance inspection, editing properties, calling methods remotely from the air console, and browsing/editing the display tree.

They made a game so you could learn the debugger, its great.
I found the best solution for me is combining as3commons-logging with Arthropod, like so:
LOGGER_FACTORY.setup = new SimpleTargetSetup(mergeTargets(new TraceTarget(), new ArthropodTarget()));
Then, if you have a client who is having issues but can't tail the flashlog, they can just fire up Arhtropod. Awesome!

I want to use WinRT API for WiFi Direct from Windows 10 SDK in Win32 Console Application. I know about C++/CX (and even made some progress going that way), but still want to make it work without this extension.
My problem is that I can't activate IWifiDirectDevice interface (from ABI::Windows::Devices::WiFiDirect) to access IWifiDirectDeviceStatics that provides an GetDeviceSelector method.
HStringReference strDevice(RuntimeClass_Windows_Devices_WiFiDirect_WiFiDirectDevice);
ComPtr<IInspectable> insp;
hr = RoActivateInstance(strDevice.Get(), insp.GetAddressOf());
This code ends up with E_NOTIMPL as a result. In Microsoft's example they used factories for activation, but ABI::Windows::Devices::WiFiDirect namespace has no factories.
Worth mentioning that IWifiDirectAdvertisementPublisher works just fine when activated the way I wrote before.
So how to activate IWifiDirectDevice from WRL?
Windows.Devices.WiFiDirect.WiFiDirectDevice is not an activatable class. You can see that by looking at windows.devices.wifidirect.idl.
You will need to use the static methods, e.g.:
HStringReference strDevice(RuntimeClass_Windows_Devices_WiFiDirect_WiFiDirectDevice);
ComPtr<IWiFiDirectDeviceStatics> wiFiDirectDeviceStatics;
hr = Windows::Foundation::GetActivationFactory(
strDevice.Get(),
&wiFiDirectDeviceStatics);
ComPtr<IWiFiDirectDevice> wiFiDirectDevice;
ComPtr<IAsyncOperation<WiFiDirectDevice*>> asyncOperation;
hr = wiFiDirectDeviceStatics->FromIdAsync(deviceId.Get(), &asyncOperation);
Consider taking a look at the Wi-Fi Direct sample.
I'm researching the possibility of using cocos2d-js by embedding it as a view inside an existing iOS app. In order to make this work, I'm going to need 2-way communication between cocos2d and the surrounding application.
After some initial investigation, I have determined that it is possible to call in to cocos using ScriptingCore:
ScriptingCore* sc = ScriptingCore::getInstance();
jsval outVal;
sc->evalString("function()", &outVal);
My question, then, is around doing the reverse. It is possible to (e.g. in response to user input) call back out of cocos2d-js to C++? Ideally, there would be a way to register a callback with ScriptingCore which could be invoked from JavaScript.
I believe it can be done, but I have not tried myself, nor can I find a good and concise example.
All I can do is point you at SuperSuraccoon's Bluetooth example and it's git page, which apparently does both ways communication between C++ and JS code.
Love this framework thus far.
That said, hit my first roadblock. I have created an MvvmCross-based library (actually a few libraries) that performs login services that will be used across multiple cross-platform applications of the same family. What I can't quite figure out is how to plug these login libraries into my other applications (which will also be using MvvmCross). I want to be able to re-use the same ViewModels and Views across these apps.
Assume that I've read and watched a lot of slodge's videos. :) Which are very good.
I think MvvmCross with two core libraries was about the closest thing to what I'm trying to do, which is just smash MvvmCross projects together and make it all magically work. But going by that post, which had some inconsistencies in the code samples, I've been unable to get this working.
There are 2 methods in Setup which tell mvvmcross where to look for Views and ViewModels. If you override these then the system should find your views and view models.
protected virtual Assembly[] GetViewAssemblies()
{
var assembly = GetType().Assembly;
return new[] {assembly};
}
protected virtual Assembly[] GetViewModelAssemblies()
{
var app = Mvx.Resolve<IMvxApplication>();
var assembly = app.GetType().Assembly;
return new[] {assembly};
}
Beyond this, the only additions to this that I'm aware of are that you might need:
to give wp some extra help in finding the xaml urls for any views which are in additional assemblies - by default mvx only looks for the xaml uri in /views, not in any other folder in any other assembly. One way to provide the xaml urls is to add a MvxPhoneViewAttribute within the View's c# file, another is to override the MvxPhoneViewsContainer to make it provide custom urls.
to adjust some of the android project settings in order to get resources shared from libraries to main project (although this functionality has gotten much better within xamarin.android this year.
My problem is every time after changing the Liferay portal-properties (and this is frequent especially at beginning of a new portal project) I need to restart the whole portal.
Some properties I can set over hook and these values will be changed after redeployment. Also that must be possible to change most portal properties at run time.
However, do you know some approach to reflect changes in portal-ext.properties without restarting Liferay portal?
As stoldark mentioned, this is not possible in a production environment at all. Since portal.properties's properties are loaded at portal start-up.
But for development you can use a tool like JRebel, some steps to configure it here. The only issue you would get with this tool is that it is paid ;-).
I know it is a very old thread but it may be helpful for someone who is looking for some type of work around
As we know there is no straight forward way for this but I did this by using java reflection and class loader.
Liferay Version : 6.x
//Loading the PropsUtil class by using PortalClassLoader
Class<?> prospsUtilClass = PortalClassLoaderUtil.getClassLoader().loadClass("com.liferay.portal.util.PropsUtil");
//getting the reload method of PropsUtil class
Method reloadMethod = prospsUtilClass.getMethod("reload", null);
//Invoking the static reload method
reloadMethod.invoke(null, null);
Reload method (re)loads the portal-ext properties to the portal so we can use new properties without restarting Liferay server.
This has also been asked in Liferay forums:
https://www.liferay.com/community/forums/-/message_boards/message/800954
But I am afraid that most properties are only read once during portal startup.
Usually, the use of a properties file as in this case has this drawback.
There's even an issue open at Liferay about this, but is still unresolved:
http://issues.liferay.com/browse/LEP-5579
If you create a hook to override portal properties, you will be able to change properties with just deploying the hook without restarting the Portal.
Be aware that you cannot modify all properties with a hook. For a list of the ones that you can modify, check out: https://docs.liferay.com/portal/6.2/definitions/.
I've just searched for reloading portal-ext.properties and landed here.
Ok - not a feature in Liferay.
So I'll use an old trick I like:
place custom properties in (liferay-tomcat-home)/conf/filename.properties
reload them whenever you want by
Properties customProperties = new Properties();
customProperties.load(new FileInputStream(new File(System.getProperty("catalina.base"), "conf/filename.properties")));
I must confess I haven't tried this in a Liferay-Portlet-Environment, but this system property ("catalina.base") should be available in this context, at least by using some Liferay-Helper-Class.
Some of the Liferay classes read their properties when initialising static field constants. E.g.:
public static final boolean ENABLED = GetterUtil.getBoolean(
PropsUtil.get(DynamicCSSFilter.class.getName()));
Basically, it is possible to reload the properties (eg via script in control-panel), but all those static constants will remain.
I'm using the WkHtmlToXSharp wrapper library in my project to generate PDF file from HTML.
I was using this library a lot of times in different PCs and, suddenly, I came across the following problem:
System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.
at WkHtmlToXSharp.WkHtmlToPdfConverter.wkhtmltopdf_convert(IntPtr converter)
at WkHtmlToXSharp.WkHtmlToPdfConverter.Convert(String inputHtml)
at WkHtmlToXSharp.WkHtmlToPdfConverter.Convert()
at WkHtmlToXSharp.MultiplexingConverter.b_8()
--- End of inner exception stack trace ---
at Sanford.Threading.DelegateQueue.EndInvoke(IAsyncResult result)
at Sanford.Threading.DelegateQueue.Invoke(Delegate method, Object[] args)
at WkHtmlToXSharp.MultiplexingConverter.Convert()
This seems to be a common problem with this library (I've found some feedback on the web about it - however no fix was provided). BTW, in my case it happens somewhat randomly. I was not experiencing this problem in other dev machines. I wonder if somebody has a fix for it. I also wonder if this is a problem with the wrapper library, if with the WkHtmlToPDF library itself.
Any suggestion? I'm also open to use another converter, as long as it is free and stable and, if possible, without spawning a new process. It must work properly and stable in all Windows versions and do a decent job converting (the HTML to be converted is fixed - contains a few pics and tables and basic CSS).
I would suggest an alternate route: simply use wkhtmltopdf.exe directly, building your own wrapper. They are not very complicated if you have control of the input and then you know exactly how to update it and how the options work. I've never encountered with that problem when using wkhtmltopdf directly (on Win7, Win server 2008 r2, Ubuntu and CentOS). They do spawn process for every conversion though.
For an example, check out the Derp class in another answer of mine regarding wkhtmltopdf. Or try something like the untested code below (your true code will be more complicated, this is just a demo/POC).
var pi = new ProcessStartInfo(#"c:\wkhtmltopdf\wkhtmltopdf.exe");
pi.CreateNoWindow = true;
pi.UseShellExecute = false;
pi.WorkingDirectory = #"c:\wkhtmltopdf\";
pi.Arguments = "http://www.google.com gogl.pdf";
using (var process = Process.Start(pi))
{
process.WaitForExit(99999);
Debug.WriteLine(process.ExitCode);
}
