I need to see the navigation flow between my pages in wechat miniprogram. I have searched the net and have not seen how I can see the pages that are in the stack.
My question is:
Is it possible to debug the page stack in wechat miniprogram from the IDE?
Use the method of "getCurrentPages()" when you need.
When the page stack change, the return data of method will not change.You must use it again to get the lastest data.
Otherwise, you can use the parameter of "debug" in "app.json".
With opening it, when the page stack change you can see it in the console tool.

I m developing a Single Page Application (SPA). So, I use to refresh the page's HTML's content dynamically using Ajax requests.
I'd like to register to the DoubleClick for Publishers program, but I m wondering if my SPA is able to integrate advertising due to its dynamic content loaded without refreshing the page.
I saw this link: https://support.google.com/dfp_sb/answer/3058726
So I assume it's ok. But I'd like to be certain before starting using DFP. Could someone confirm please?
Then, sometimes I m using external html pages that I still load using Ajax. Should I consider writing the advertising banners JavaScript inside these external views, or directly inside the master page of my app?
Last question: How can I manage users having an adblocker software installed? Am I allowed to detect the presence of an adblocker software using JavaScript and then execute some specific code for this kind of users?
I'm working in a SPA and working with DFP successfully. Here is my feedback to your questions:
So I assume it's ok. But I'd like to be certain before starting using
DFP. Could someone confirm please?
Yes, you can refresh the banners using the method you are refering in the link you shared
Then, sometimes I m using external html pages that I still load using
Ajax. Should I consider writing the advertising banners JavaScript
inside these external views, or directly inside the master page of my
app?
To load them externally will bring you to lower performance results. You can control everything from the main page and you will have better results.
Last question: How can I manage users having an adblocker software
installed? Am I allowed to detect the presence of an adblocker
software using JavaScript and then execute some specific code for this
kind of users?
This is something I have not started to work on it but you can detect (like forbes.com is doing on it website) and there are also projects on dealing with this.
In my endeavour to gain use of the Youtube API I am required to follow the procedure defined here.
In this link there exists a Prerequisites section that states:
Register your application with Google so that it can submit API
requests.
This takes me here which is a page Titled: "Registering your Application". This page contains instructions stating:
To register a new application, do the following:
Enter the Google Cloud Console https: //cloud.google.com/console [hit my link limit LOL]
Select a project, or create a new one.
In the sidebar on the left, select APIs & auth. In the list of APIs, make sure the status is ON for the YouTube Data API v3.
In the sidebar on the left, select Registered apps.
I have done all of the above. I have also clicked on the project taking me to another page. I am however, unable to register the application.
My question to you is "Where do I find the "Registered apps" because it's not in the sidebar on the left.
Google even provide a video on the instructional page stepping you through it. Unfortunately the video appears to be for an older site.
I am running Firefox 25.0.1. and it doesn't work for me so any guidance would be appreciated.
Instead of Registered Apps, in new version you'll go Credentials under API's and Auth and create your keys there.
I tried everything to help you out but i couldn't find "Registered Apps" too. Have you ever tried "Credentials" ? I think it works for the same way.
They don't care much about updates i guess. That's why they did not renew the instructions and the video..
I keep reading that an ASP.NET based web site should have custom errors enabled in the web.config because exceptions will show a stack trace.
I may have a faulty memory (currently don't have access to an ASP.NET website under development), but I thought as long as Compilation debug="false" in the web.config file, then the stack trace will not be displayed.
Is my understanding correct about the debug flag and display of the stack trace? If so, then even if custom errors are not enabled, then won't the only message displayed to remote users for an exception be a the non-descriptive message:
"The page cannot be displayed because an internal server error has occurred."
If so then wouldn't it be OK, from a security perspective, to not display a custom error page for the exception?
No, a stack trace will still be shown even if the debug flag is off, but it will not have line numbers for each call in the stack.
The non-descriptive message is what the browser usually shows instead of the actual error message from the server, unless you change the configuration. Anyone wanting to expose information by causing error messages would know how to do this.
Displaying the stack trace isn't a security risk in itself, but it does expose some information that could potentially make it easier to hack the site. A hacker might for example get a clue as to what's done to sanitase the input and find a way around it.
Custom error messages should almost always be prefered over the default error thrown. It gracefully sends your user to a location where they can keep browsing your site without having to go back and try again.
Turning DEBUGGING off in your web.Config is VERY important and goes beyond just not showing the line numbers and stack trace... it also tells the compiler to build in release mode which optimizes performance dramatically. As soon as your app goes to production, all debugging should be disabled.
I want to go live with my site.
...but I need help with a security violation I am incurring.
I've seen various threads on this forum regarding a crossdomain.xml file to include and link to, but I don't get it... no matter what I try I still end up with the same result. You'll note below that it is not recommended to use crossdomain hacks.
FWIW, this only happens when I export a release build... I can load the php data w/out an issue in my debug/developing phase locally in Flex.
What gives? When I make a PHP based request for data I always get this error popping up:
Error #2044: Unhandled securityError:.
text=Error #2048: Security sandbox
violation:
http://alubow.com/jml_testing/viewable/alubow_project.swf
cannot load data from
http://www.alubow.com/jml_testing/foldergrab.php?ipath=assets/bitmap/portrait_thumbs/&tpath=assets/bitmap/portrait_imgs/.
at utils.php::DirectoryReader() at
alubow_project/newScroller() at
alubow_project/mainClickOut()
Is there code I need to add to get this to work? Do I need to configure the server I am using?
I will need to go live with this site soon and these errors I am getting both locally and serverside (via a browser) are unacceptable.
COULD THIS BE A PROBLEM WITH THE FLASH PLAYER I HAVE INSTALLED?
I have the debugger version of flash player 10.

The problem is with the www prefix. I guess you are trying to load a page with out the www subdomain and the URL you are looking for does have that prefix.
Now, what you need to do is one of the following:
change the request url
add both www.yourdomain.com And yourdomain.com to the crossdomain.xml
call the url dymanicaly. this is the best solution but needs some more work. you can get it done using ExternalInterface and connection to JS here. OR you can use the BrowserManager.
Enjoy!
It may be because your app is requesting from www.alubow.com when hosted from alubow.com, which triggers a request for http://www.alubow.com/crossdomain.xml, which doesn't exist. You could refer to your app as www.alubow.com/jml_testing/viewable/alubow_project.swf and avoid the error.
Alternately, you could add a crossdomain.xml file to www.alubow.com.
I know this is weird but for local files loaded through the flash player you probably just need to hit this page. Look near the top right for something that looks like an example image. It's actually a Flex application. Click successive tabs until you read the Global Security Settings panel (currently 3rd from the left, with an image of a globe and padlock). Select the "Edit locations" menu, and choose "Add location". You can then add your swf or your folder of swf's into the whitelist and they'll be able to access outside resources magically.
I am building a Flex Application that calls a .aspx page on the same webserver which builds a PDF report using SQL Reporting Services. When the report is built it prompts the user to open or save the PDF.
We are trying to find a way to display a Progress Bar to let the user know that the report they requested is being built, and then destroy the Progress Bar once the report is finished being built.
I've tried opening a new window using JavaScript and trying to catch when the window closes, as well as trying XMLHTTPRequest, but nothing to seems to work.
Does anyone have any suggestions?
There are 2 options:
Use the FileReference class in Flex to programmatically invoke your aspx file. You will be able to track the progress of the call from within Flex by listening to its events. But the users can only save the PDF, not open it.
Have an intermediate HTML page that displays a loading icon and then refresh itself to your PDF generating ASPX page. Encode your aspx url along with parameters etc and set it as a parameter to this intermediate page so it knows what to load.
If you don't have control over the page to be able to put JavaScript on it to hit a URL (or call back to the parent/opener), then you might consider whipping up an aspx page of your own to host a ReportViewer control, and display the report inside of that. This would require you to create a .NET website with a page and a web.config - you wouldn't need to do more than make it receive any parameters your report needs, and it would be do-able via inline-to-the-aspx code as opposed to requiring in-depth .NET knowledge.
Or, you could hit the SS-RS API and render the report directly. Here, you'd craft a URL with parameters for the report on the SS-RS API site to accept. I think, though I don't know for sure, that the SS-RS UI uses the API itself behind the scenes. By default the API is hosted in a site called "reportserver" - you might sniff HTTP traffic while the report is being rendered to get you started with the URL that you'd need to hit.
Another option not mentioned here is to create a .Net webservice, add it to your flex project and when it hits the result handler you know the file is created at that point.
