I'm working on a windows universal app. I want to show the user an image. The image is located in a subfolder within my assets folder, in both the phone and the windows folder.
I'm trying to put the image in a variable in a class that is in the shared folder. I am continously getting uri exceptions.
My code looks like this:
Uri uri = new Uri("/Assets/Image/avatar_anonymous.png");
chat_profilepicture_Bitmap = new BitmapImage(uri);
I've tried different urls, with and without capitals, the entire path "C://blablabla", and many more. Nothing seems to be working. I have also tried: pack://application:,,,/ which was suggested by multiple stackoverflow threads. But no luck there.
I'm thinking the problem lies in the image being in another project, is there a way to get around this? Or if this isn't the problem, what am I doing wrong?
Try this
Uri uri = new Uri("ms-appx:///Assets/Image/avatar_anonymous.png");
Hope this helps
In Windows Universal App, You can use Image Resource with ms-appx or ms-appdata.
ms-appx means using resource in App Package
ms-appdata menas using resource in floder of local, temp or roam.
So the uri can be written like this:
new Uri("ms-appx:///Assets/Image/avatar_anonymous.png", UriKind.Absolute);
or
new Uri("ms-appdata:///LocalFolderName/demo.png", UriKind.Absolute);

I am building a website and along the way I used imgur to store the image that i was using in it but I decided to created a folder in my app to store them.
Since I'm not using imgur anymore, i needed to change my path to find the image and that's where the problem appeared, I can't find the image.
The structure looks like that:
webapp_folder
|_node_modules
|_image_folder
|_public_folder
|_views
|_partials_folder
|_main.js
|_app.js
|_package.json
In main.js, I use one of the image in image_folder and the path to the image looks like: src="../image_folder/image.png" but that's where I got the 404 error.
I've tried putting the image in the same folder that the main.js so the path would look like src="image.png" but still getting this error.
So i guess it's not a path's problem but I've no idea what it could be.
Hope I could make it clear!
I'm using node.js and express.
You need to make routes to the assets.
app.use(express.static('image_folder')
Whenever you are using an asset there are multiple ways to include that in your project.
In your case, whenever an image is loaded it is actually loaded by the browser using network calls from client side. Not server side. So client side code doesn't have access to internal paths (for ex: /usr/local/ kinda paths). Whenever they fetch something it is relative to the host, maybe in your case localhost so, fetching /image.png is fetching localhost/image.png but your app doesn't have route to those image files. So, we make routes for all the assets which is done by express.static
Another way is you can actually require the image. So, bundlers (with proper config) make some public folder and put the assets to that folder. react/vue apps by default do this.
What is the correct way to display a HTML file downloaded and saved in the file system? I am able to download and save the html page in the .cn1 folder on Simulator but it doesn't display. I tested using the Page.html sample file found in the old Kitchen Sink demo.
Also, how can I use hardcoded paths like file:///storage/emulated/0/Folder/Page.html instead? I have tried but nothing appears in common folders in the phone e.g. the Android folder. Below is what I have done so far!
`Form fm_brw = new Form();`
`fm_brw.setLayout(new BorderLayout());`
`FileSystemStorage fs = FileSystemStorage.getInstance();`
`fs.mkdir(fs.getAppHomePath() + "SampleFolder");`
`Util.downloadUrlToFile("http://somesite.com/Page.html", fs.getAppHomePath() + "SampleFolder/Page.html", true);`
`BrowserComponent browser = new BrowserComponent();`
`browser.setURL(fs.getAppHomePath() + "SampleFolder/Page.html);`
`fm_brw.addComponent(BorderLayout.CENTER, browser);`
`fm_brw.show();`
You can't hardcode paths on phones as those differ even on the same phone for new installs to keep app isolation.
Your approach is correct but I'm assuming the html refers to images and other resources which are now unavailable so the process of downloading an HTML file for offline viewing is more complex as you would need to download all the resources then edit the HTML source to reference local files instead of server files.
#Shai Almog - Happy 2018 and please accept my apologies for the delayed reply. I figured out the reason for the webpage not diplaying... apparently, you have to add the "file://" when setting the url i.e. browser.setURL("file://"+str_homePath+str_filePath);
If this is not by your design then I can file an RFE.
I'm getting an error when I try to create a directory (i.e. snapshots) in my wp8 app but I don't understand why it works fine when in my emulator and when I transfer my app directly from my laptop onto my phone but when it's coming from the wp8 store, it generates the following error:
System.UnauthorizedAccessException: Access to the path 'Snapshots\' is denied.
I don't know if this is ok to do but everywhere I deal with files, I don't bother specifying a path but just a folder as I assume that it will go into the "app path\". Is this not the case?
2 Questions arising from the problem:
Why does it work with local app and not app downloaded from the store? Are access rights different?
If I'm not allowed to create files directly into the app's folder (no path provided, just a filename i.e. data.xml) or sub-folder (sub-folder only + filename provided i.e. Snapshots\test.jpg), where should I store my data (xml, jpg, etc...)
Thanks.
I found out the hard way that you should not try to write data directly in the root folder of a wp8 app as it is an "install folder". I found this interesting article/pdf from Microsoft Files and Storage in Windows Phone 8. Check out page 7, where it clearly explains the difference between installation and local folder.
The question originally originate trying to figure out why my live tile would not update and there were numerous reasons, so while unrelated to this question, I'll include them anyway as it may help someone in the future.
Folder creation problem: See above. Still can't explain why it works when app is transferred from pc to phone but when coming from the app store, it doesn't. Point is that I was going about it the wrong way and you should not be storing files in the root folder, even in a sub-folder as it can't be created in this location. You should use isolated storage or data storage.
Files still failed to update the live tiles when storing them in StorageFolder (LocalFolder). I then found these 2 articles which clearly state that images used by the Live Tiles should be stored in Isolated Storage but in a specific location i.e. Shared\ShellContent
WP8 Tip: Creating Live Tiles with Dynamic Images
Capturing image from camera and updating live tile
The minute I applied what was suggested i.e. use the specific path and use isolated storage, it sorted all my problems i.e. creating folder, creating file, etc...
Please note that while it states that you should store the file in \Shared\ShellContent, it also highlights that it can be stored in any sub-folders within that folder, so in my case, I've got \Shared\ShellContent\\Snapshots and it work as expected.
Again, if time permits I'll investigate the StorageFolder some more as I'd like to get it to work as it is the recommended method to use with WP8/WP8.1 by Microsoft and Isolated Storage appears to be recommended for WP7.
I hope it will save you some time if you encounter similar problems.
(ActionScript3) Hi, I'm trying to work out why a URLRequest is failing when viewed via a third party website. Ideally any error could be pointed out in the below code, however, I think it's fine as similar things we do work fine.
Next to ideal would be URLRequest error handling, how can I find out WHY the URLRequest is not pulling the information from time.php? Even if it's just output to a textbox on the timeline (everything works fine when done from the testing environment)
Many thanks
Craig
Scenario:
domain.com (Server 1): file.swf uses a URLRequest to load domain.com/time.php?a=b (so the PHP and the SWF are both hosted on the same domain and server)
example.com (Server 2): PHP page embedding file.swf (which in turn URLRequests time.php)
Outcomes:
When you access file.swf directly via browser, it loads the data from time.php just fine
When you view the page file.swf is embedded on, on Server 2 the loading fails
file.swf
var loaderNameHolder;
var loaderNameHolderLoader:URLLoader = new URLLoader();
var loaderNameHolderURLRqst:URLRequest = new URLRequest('http://domain.com/time.php?a=b');
loaderNameHolderLoader.addEventListener(Event.COMPLETE, loaderNameHolderURLFunc);
loaderNameHolderLoader.load(loaderNameHolderURLRqst);
function loaderNameHolderURLFunc(e:Event):void{
loaderNameHolder = loaderNameHolderLoader.data
gotoAndStop(loaderNameHolder);
}
Security
There is a crossdomain XML in place on the domain's root folder, it seems to make no difference (or is not being referenced/used correctly) however as mentioned similar things I do work fine without modifying this XML
It sounds like a security issue, although you say that you have the crossdomain file in place.
Have you checked the http calls with a tool like Charles (http://www.charlesproxy.com/)? This is definitely the best way to debug such a problem.
Thanks for the tips above, they'll be great resources to keep.
The actual issue was that the Requested URL didn't include "www" (I think because the SWF is embedded with the WWW so it was coming from an "outside" domain. I think I need www.domain.com in my own security XML).
Craig
try adding this code
Security.allowDomain("*");
Security.loadPolicyFile("http://domain.com/crossdomain.xml");
and read about crossdomain.xml using links given here: https://stackoverflow.com/a/9728845/2234089
All the walkthroughs I've seen specify either desktop, local files as the initial view when calling browseForOpen.
Is there a way to have the air application remember the last location a file was loaded from and default back there?
If necessary I suppose the path could be written to the local db, but even still, I do not know how to get the filepath of the loaded file.
You can use File.nativePath and File.resolvePath.
A few years later, perhaps, but thought this might help someone in the future.
var file:File = new File();
file.browseForOpen("Open");
This will open the last location.
