It doesn't appear that I can provide both HTML content and file content in the DataRequestedEvent handler.
If I provide HTML content (via args.Request.Data.SetHtmlFormat(xxx)) and file (via args.Request.Data.SetStorageItems(xxx)) the Share charm says "There's nothing to share".
Anyone got any ideas or is this by design?
var htmlExample = "<p>Here is our store logo: <img src='images/logo.png'>.</p>";
var htmlFormat = Windows.ApplicationModel.DataTransfer.HtmlFormatHelper.createHtmlFormat(htmlExample);
request.data.setHtmlFormat(htmlFormat);
full exemple here http://msdn.microsoft.com/en-us/library/windows/apps/windows.applicationmodel.datatransfer.datapackage.sethtmlformat
If time for generating the content is more that 200ms share charm says "There's nothing to share".
You can avoid this problem with DataProvider.
args.Request.Data.SetDataProvider(StandardDataFormats.Html,
new DataProviderHandler(this.OnDeferredHTMLRequestedHandler));
args.request.Data.SetDataProvider(StandardDataFormats.StorageItems,
new DataProviderHandler(this.OnDeferredStorageItemsRequestedHandler));

I'm writing a vscode extension where I'm hoping to squeeze more dynamic functionality out of markdown preview. Effectively the problem I'm trying to solve is:
In markdown preview, there's a checkbox
When user clicks the checkbox in markdown preview, send a message/event to the vscode extension runtime
Vscode extension can listen for this message/event and store the action in local storage
Checkbox state is saved - and subsequent renders of the markdown preview can use this action
Ideally, I'd like to do this while keeping the default markdown preview security (https://code.visualstudio.com/Docs/languages/markdown#_strict). After all, I don't need the extension to or markdown preview script to talk to a remote server - I just want them to be able to talk to one another.
Problem as code
To write the problem as sudo code, I want my markdown preview script to contain something like:
const button = ... // get button element
button.addEventListener('click', () => {
... /*
* Send a message to the vscode extension. Something like:
* `vscode.postMessage('vscode.my-extension.preview-action' + value)`
* (which I can't get to work, I'll discuss why)
*/
});
where then my extension can listen for messages like 'vscode.my-extension.preview-action'.
What I've Tried Already
I have tried acquireVsCodeApi() but because the markdown extension already does that, I can't do it again in the subsequent loaded script. I've also tried registering a uri handler but as far as I can try out the preview script still needs to fetch to that uri, which is still blocked by the default markdown security settings.
Perhaps markdown preview scripts are not the place to do this kind of thing, but I just wanted to leverage as much as possible that's already there with the vscode markdown extension. I want to supplement markdown but not replace it, the functionality I want to add is just icing on markdown documentation.
I've read https://code.visualstudio.com/api/extension-guides/markdown-extension#adding-advanced-functionality-with-scripts and it doesn't tell me much about markdown extension scripts capabilities and limitations.
Thanks to #LexLi I looked at some of the source code in the markdown extension and was able to come up with an ugly hack to make this work in preview scripts. Markdown allows normal clicks. And vscode extensions can handle normal clicks. I've paraphrased the code so there could be small syntax errors.
In the extension I did this:
vscode.window.registerUriHandler({
handleUri(uri: vscode.Uri): vscode.ProviderResult<void> {
console.log(`EXTENSION GOT URL: ${uri.toString()}`);
},
});
Then I made sure my extension/preview script put this in the document
<!-- in the preview script I place a button like this -->
<!-- it even works with hidden :) so I can do more app customization -->
<a
hidden
id="my-extension-messager"
href="vscode://publisher-id.my-extension"
>
cant see me but I'm there
</a>
Then my preview script I can even set href before faking a click:
const aMessager = document.querySelector("#my-extension-messager");
console.log('client is setting attribute and clicking...')
aMessager.setAttribute('href', 'vscode://publisher-id.my-extension?action=do-something');
aMessager.click();
console.log('client clicked');
Logs I saw (trimmed/tweaked from my particular extension to match the contrived example):
client is setting attribute and clicking...
client clicked
[Extension Host] EXTENSION GOT URL: vscode://publisher-id.my-extension?action%3Ddo-something
It's a hack but I can do a lot with this. Within the URL I can encode data back to the extension and kind of pass whatever I want (as long as data is relatively small).
In my application i am binding several properties to a custom user control, and everything works fine, except the images are not showing. For binding i have used the following codes:
Categories.Add(new Models.Category { Name = "Pizza", Count= 4, ImageUri = new Uri("Images/pizza.png", UriKind.Relative) });
I have also tried with different urikinds but the images are never showing.
what could go wrong? The images are in my solutions Images folder.
Use the ms-appx URI scheme:
ImageUri = new Uri("ms-appx:///Images/pizza.png");
Take care to really write ///.
Also make sure that the Build Action of the image file is set to Content, as pointed out in the other answer. Setting Copy to Output Directory does however not seem to be necessary.
Be sure you set the properties of the image so that it is available during runtime. Sometimes if employing Design Time data in Blend, you will see the images in Design Time, but then nothing during run time. The reason is that the images were never deployed with the rest of the solution. Be sure the Build Action on each image is set to Content and I usually set the Copy to Output Directory to Copy if Newer.
Follow up to this question:
apply downloaded CSS on windows 8 metroUI app
So, yes, Windows says "for security reasons, you cannot navigate to HTML you have downloaded to this location and you cannot run any executable or potentially executable code, such as script or CSS. It is intended for media such as images or videos and the like."
But I really, really want to use that css file from my local storage. Shouldn't I be able to use the execUnsafeLocalFunction method to bypass this restriction like this?:
MSApp.execUnsafeLocalFunction(function () {
el["href"] = "ms-appdata:///local/style.css"
});
It still throws "An app can’t load remote web content in the local context."
I also tried just reading the file with localFolder.getFileAsync and readText, but nothing seems to help. Is there really no way to work around this?
I think I found a way to get the CSS to load.
I tested the code below by adding a css file that sets the body background to red in the local storage folder.
The code reads the contents of the file, creates a style tag in the head and adds the content of the css file to the style.
var url = new Windows.Foundation.Uri(filename);
Windows.Storage.StorageFile.getFileFromApplicationUriAsync(url).then(function (file) {
Windows.Storage.FileIO.readTextAsync(file).then(function(text) {
var style = document.createElement("style");
style.innerText = text;
document.getElementsByTagName("head")[0].appendChild(style);
});
});
I am working in Ektron 8.6.
I am creating a Custom widget for the creation of XLIFF file for a corresponding content in workarea by passing it's Content ID.
I have referred the files in the workarea folder of my ektron website to get the Ektron API's to emulate this functionality(as this is already handled by ektron).I got some inputs form the following file:Workarea\controls\content\localization_uc.ascx.cs and tried the following code:
Localization temp = new Localization();
temp.StartExportContentForTranslation("36,12,50", "1031,1041");
I also tried:
Ektron.Cms.ContentAPI m_refContentApi = new Ektron.Cms.ContentAPI();
Ektron.Cms.BusinessObjects.Localization.L10nManager localizationManager = null;
localizationManager = new Ektron.Cms.BusinessObjects.Localization.L10nManager(m_refContentApi.RequestInformationRef);
localizationManager.StartExportContentForTranslation("30,35", "1078,1052");
localizationManager.StartImportTranslation();
But this code doesn't seems to work.
What i am i doing wrong here?
I found another SO question regarding the same issue.But that loop also is not having a solution to the issue.
Can someone help me in fixing this issue?
I want to implement the Share source contract in my WinRT C# Metro app (Windows Release Preview). My app is storing arbitrary files. Not in the filesystem, but instead I get the data over a WCF service as byte[]. Now I want to share such "files" in my app.
The only possibility I've seen with a standard data format is using the SetStorageItems() method on the DataPackage. Thus I'm facing the challenge to convert the data from my byte array to a StorageFile, which can be shared. I found the StorageFile.CreateStreamedFileAsync() method and wanted to use it in this way:
// filename: string
// fileContent: byte[]
// ... setting DataPackage title and description ...
DataRequestDeferral deferral = args.Request.GetDeferral();
var file = await Windows.Storage.StorageFile.CreateStreamedFileAsync(filename,
async stream => await stream.WriteAsync(fileContent.AsBuffer()), null);
args.Request.Data.SetStorageItems(new List<IStorageItem> { file });
deferral.Complete();
It compiles fine, but it doesn't work as expected. I've tried the sharing with the standard Mail app. The Mail share view opens and I can create a new mail. The file is shown without thumbnail (as expected), but the e-mail can't be sent. It's showing the sending progress for several minutes and then an error occurs: "Couldn't share {filename} with Mail.". The share charm shows "Something went wrong" and "[...] Mail can't share right now. Try again later.".
It works perfectly when I load the StorageFile from the file system: the mail opens and is sent within seconds, no problems here. So either I'm using CreateStreamedFileAsync() wrong or there's a bug in this method, what do you think?
In the callback passed into CreateStreamedFileAsync, you need to actually dispose of the object - that signals to the OS that you are done.
Wrote a complete example here
The Mail app is not a target for sharing files. From http://blogs.msdn.com/b/b8/archive/2012/06/14/building-the-mail-app.aspx: "Mail supports sharing text, links, and pictures."
Remember that there are 2 parts of the Share contract: Share sources and Share targets. As you know, there are many different data formats that can be shared between them, like text, pictures, URIs, and files. The full list of the different data formats that are supported is at http://msdn.microsoft.com/en-us/library/windows/apps/hh771179.aspx.
I recommend that you use the Share Target Sample app to test that your file is being shared properly - share to this and it will display everything that is being shared from your app as a source (and it does accept files for sharing). You can download it from http://code.msdn.microsoft.com/windowsapps/Sharing-Content-Target-App-e2689782. You can also use the Share Source Sample app as an example and leverage code from this app; you can download it from http://code.msdn.microsoft.com/windowsapps/Sharing-Content-Source-App-d9bffd84.
Hope that helps!
Ok, perhaps the preview version of the Mail app doesn't handle the sharing target contract correctly. Using the SDK sample app "Sharing Content Target App" from http://code.msdn.microsoft.com/windowsapps/Sharing-Content-Target-App-e2689782, sharing a StorageItem created in memory with the StorageFile.CreateStreamedFileAsync() method posted above works fine.
Thus, that's the way you should go when you want to share in-memory byte[] arrays. For testing, make sure that the share target app doesn't run in Visual Studio when you want to share data from another app with it. Then the sharing sidebar mysteriously will disappear automatically...
