I am trying to create a SecondaryTile using a JPG that I extracted to temporary storage (). When I create a URI from this file I get an error from the constructor of the SecondaryTile class. The error message I get is very helpful, it says "Incorrect parameter".
I have tried passing in a URI to the filename like this:
new Uri("file://C:/Users/{username}/AppData/Local/Packages/{myAppPAckage}/TempState/{filename}.jpg");
I have also tried ms-appx even though I don't think that is the right way given my file is stored in temporary app storage.
new Uri("ms-appx:///C:/Users/{username}/AppData/Local/Packages/{myAppPAckage}/TempState/{filename}.jpg");
Using ms-appx:/// as the prefix allows the tile to be pinned without error but the image does not display.
The file system path that I am getting is obtained from ApplicationData.Current.TemporaryFolder.
I found this documentation that provided the uri prefix for the folder I am using to source the image.
new Uri("ms-appdata:///temp/{filename}.jpg");
Unfortunately, this also gives the Incorrect parameter error.
How do I use an image file that is stored in App Temporary Storage?
I needed to use ApplicationData.Current.LocalFolder and the prefix "ms-appdata:///Local".

I am attempting to determine if a folder is empty.
My current method involves using a GetMeta shape and running the following to set a Boolean.
#greater(length(activity('Is Staging Folder Empty').output.childItems), 0)
This works great when files are present.
When the folder is empty (a state I want to test for) I get
"The required Blob is missing".
Can I trap this condition?
What alternatives are there to determine if a folder is empty?
I have reproduced the above and got same error.
This error occurs when the folder is empty, and the source is a Blob storage. You can see it is working fine for me when the Source is ADLS.
for sample I have used set variable.
inside false of if.
if folder is empty:
Can I trap this condition?
What alternatives are there to determine if a folder is empty?
One alternative can be to use ADLS instead of Blob storage as source.
(or)
You can do like below, if you want to avoid this error with Blob storage as source. Give an if activity for the failure of Get Meta and check the error in the expression.
#startswith(string(activity('Get Metadata1').error.message), 'The required Blob is missing')
In True activities (required error and folder is empty) I have used set variable for demo.
In False activities (If any other error apart from the above occurs) use Fail activity to fail the pipeline.
Fail Message: #string(activity('Get Metadata1').error.message)
For success of Get Meta activity, there is no need to check the count of child Items because Get Meta data fails if the folder is empty. So, on success Go with your activities flow.
An alternative would be
Blob:
Dataset :
where test is the container and test is the folder inside the container which I am trying to scan (Which ideally doesnt exist as seen above)
Use get meta data activity to check if the folder exists :
If false, exit else count for the files
I have an issue with text files that are save to a blob storage and then iterated through using a logic app. The files come from a very old (but unfortunately very important) system. Access to it is highly restricted, so I have zero control over how the files are created.
They are uploaded to our blob storage without any suffix and with ANSI encoding. If I view their file contents through the Azure portal I can see that non-standard characters (in this case åäö) are corrupted :
[corrupted chars][1]
I assume this is because Azure assumes UTF-8 encoding? The problem occurs when I use a logic app to iterate through the blobs, then getting the file contents and placing them in a string variable. As far as I understood it, Azure logic apps should automatically convert the encoding to UTF-8, but this doesn't seem to happen, since the characters åäö in the string variable are still garbled.
The data from the string variable is used as input data for an Azure function that needs to be able to see the åäö characters properly. Manually converting the files to UTF-8 before uploading them solves the issue, but this is not practical, since this data flow is supposed to be automated.
The file contents are extracted like so:
[file contents to variable][2]
Infer content makes no difference, neither does renaming the files with a proper .txt suffix.

I have come up with an AppleScript, to monitor my VPN connection from VPN Tracker. So far I got the code working, meaning it shows the correct state as text. I created two PNG files, which I converted into Base64 and would like to use those as the status output, instead of just having text. The reason for the Base64 conversion of the images is, so I can share the script with others, without needing to share the actual images as well and expect the user to put them somewhere on his Mac.
I am however unsure of how to decode those Base64 strings in AppleScript, so it shows the actual image in the end.
This is the code I have so far (with the text output)
set conn_state to "" as string
if application "VPN Tracker 365" is running then
tell application "VPN Tracker 365"
try
if name of groups contains "group_name" then
set conn_state to state of connection of group ("group_name") as string
if conn_state = "On" then
return "VPN active"
else
return "VPN inactive"
end if
end if
on error
return "An error occured"
end try
end tell
end if
I did do some research on the internet but could not find anything that would help me, solve this problem, or I was maybe not using the right search terms.
Any help would be much appreciated. Thanks in advance
"The reason for the Base64 conversion of the images is, so I can share the script with others, without needing to share the actual images as well and expect the user to put them somewhere on his Mac."
Consider taking a different approach. The following solution will enable the image(s) to be bundled within your Applescript and avoid having to Base64 encode/decode them:
Save your AppleScript as an "Application" format via the AppleScript Editor.
Locate your resultant application via the "Finder"
Click on it while pressing the ctrl key.
Via the context menu choose "Show Package Contents".
Copy your .png image(s) to the Contents/Resources folder.
Then in your code access the path to the image as follows:
# Get the pathname to where this script resides in the filesyetem.
set pathToMe to (path to me) as text
# Create the full pathname to the image
set pathToPng to pathToMe & "Contents:Resources:img.png" as alias
# Just a demo to illustrate that the image path can be accessed.
tell application "Preview" to open pathToPng
Note: This example code assumes you've copied an image named img.png to the Contents/Resources folder. It firstly obtains the path to wherever your app is located and assigns the images path to the pathToPng variable
Edit:
Or, as #user3439894 kindly mentioned in the comments, simply use the following code to obtain the path to the image(s) directly:
# Create the full pathname to the image
set pathToPng to path to resource "img.png"
# Just a demo to illustrate that the image path can be accessed.
tell application "Preview" to open pathToPng
Note: This utilizes path to resource to obtain the path of the image, and the aforementioned steps 1-3 are still necessary
so I am trying to download an image from firebase storage like this using cloud function
const bucket = storage.bucket("myApp.appspot.com")
const filePath = `eventPoster/${creatorID}/${eventID}.png`
await bucket.file(filePath).download({
destination: tmpFilePath
})
but the problem is, I can't ensure the image is always in the png format, it can also be jpeg or jpg
I will get error like this if I hard code it like that
Error: No such object: myApp.appspot.com/eventPoster/user1/ev123.png
so how to check if a path is valid or not or how to make a code that can work dynamically with other image extension ?
Posting as Community Wiki, because I based part of it in a comment and so other members of the Community can feel free to edit it.
As mentioned in the comments, you can use the method exists(), to check if a specific file exists in your bucket. This way, you will not an issue, in case the file doesn't exist when you are trying to return it. This would be the best way for you to check only for files existing, with the name based in the ids as you are basing your name structure.
Besides that, as clarified in this other post from the Community here, you can restrict the file types in your bucket in case you are using the POST method to upload files, otherwise, you won't be able - which can also, be an alternative. In case you are not using POST, as mentioned as well in this other post, you can try to construct a Cloud Function that will check for the file type before it uploads the file to the bucket, which would make your application only upload specific files.
In case you would like to check on how to upload files to Cloud Storage using Cloud Functions, you can check this tutorial here: How to upload using firebase cloud functions
Unfortunately, these seem to be the only available options right now, but I think they are a good start for you.
Let me know if the information helped you!
You can use the exists method on a file to check if your PNG is present or not. You can also change your code and use the getFiles() method. As you can see, you can put options, and one named "prefix". In your case you can have this
bucket.getFiles({
prefix: "eventPoster/${creatorID}/${eventID}"
}, <callback>);
Here you will list all the file with the prefix: PNG, JPEG and others. make your code smarter to leverage this dynamic answer
Does anyone know how to get the full path of a DirectoryEntry object in a Chrome Packaged App, without any tildes or other shortcuts?
I am writing a Google Chrome Packaged App. My app has a button where a user can choose a directory using chrome.fileSystem API. When the directory choice comes back to my app, it is represented by a DirectoryEntry object, which is defined in the File API. The object looks like this in the console:
DirectoryEntry {
filesystem: DOMFileSystem
fullPath: "/to_read"
isDirectory: true
isFile: false
name: "to_read"
__proto__: DirectoryEntry
}
I am using Windows and the full path of the directory is
C:\Users\David\Desktop\to_read
I would like a function that can return that path or something close. Unfortunately, the closest thing I found is chrome.fileSystem.getDisplayPath, but that returns the following:
~\Desktop\to_read
The return value from getDisplayPath is not useful to me, because I want to get the full name of the directory (including the drive) so I can compare it to some other full directory paths I have.
I tried calling toURL() on the DirectoryEntry and it returned an empty string.
A bit about my project: I want to write an iTunes library synchronizer as a Chrome Packaged App. The iTunes library XML file contains full paths like file://localhost/D:/David/Music/Bob/Bob%20Album/01%20Bob.mp3. The user will give my app access to his music folders, and I want to be able to tell if he gave me access to the right folders.
The only full paths available are those returned by getDisplayPath.
The mediaGalleries API may be a better fit for your project: http://developer.chrome.com/apps/mediaGalleries.html#iTunes.
If you have a full path path/to/the/file.mp3 and you want to load the file directly with tis you can do it but the solution is not perfect. Use the chrome.mediaGalleries API to ask where the user saves his music (in your case), then you can write a loop who check if one of the path repository is equal to a gallery.
For example if you got a file path/to/the/file.mp3 from the xml file and your galleries list looks like ["D", "to", "Videos"], write a function to check if each component of the file's path is a gallery. In this case your code will find "to", so you can launch a second function who use "the/file.mp3".
The second function has to use the given path and find if the gallery contains the right folders and finally the right file (use this example by Google). In the case you're trying to find "the/file.mp3" with the gallery to your loop has to find a directory named "the" then "file.mp3" (write a recursive function), if you find the file open it, otherwise come back to the first function if you haven't check all the galleries or all the path's component.
This is currently (2014-01-10) not a feature of Chrome, but I have suggested it and they are working on it:
