I'm trying to create a Media programmatically in Umbraco 7.4.1 but when I try to use MediaType.File I'm getting the error
No PropertyType exists with the supplied alias: umbracoWidth
But when I change it to MediaType.Image its' saving and working properly. When I try to view the CMS it is indeed the mediaType File doesn't have a property of width. So I'm not sure why upon executing the media.SetValue("umbracoFile", filename, stream); it's trying to look for a property of umbracoWidth even though I was using MediaType.File
Below is how I define my code
string[] filePaths = Directory.GetFiles(AppDomain.CurrentDomain.BaseDirectory + "uploads");
foreach (string filePath in filePaths)
{
using (Stream stream = System.IO.File.OpenRead(filePath))
{
string filename = Path.GetFileName(filePath);
IMedia media = Services.MediaService.CreateMedia(filename, Constants.System.Root, Constants.Conventions.MediaTypes.File);
media.SetValue("umbracoFile", filename, stream);
Services.MediaService.Save(media);
}
}
But if I change the code from Constants.Conventions.MediaTypes.File to Constants.Conventions.MediaTypes.Image it's working correctly but the problem is the media type is not correct. Specially if i'm uploading a video or PDF file. Though it was successfully able to create a new media but the type will be wrong since it's specified as Image. I want to know how to solve the issue when using mediatype File
You need to switch manually the media type when uploading.
Eg. check on the file extension if it is gif/jpeg/jpg, the change to Image, otherwise use File.
Internally in Umbraco they use this code to know if the file is an image (or not):
/// <summary>
/// Gets a value indicating whether the file extension corresponds to an image.
/// </summary>
/// <param name="extension">The file extension.</param>
/// <returns>A value indicating whether the file extension corresponds to an image.</returns>
public bool IsImageFile(string extension)
{
if (extension == null) return false;
extension = extension.TrimStart('.');
return UmbracoConfig.For.UmbracoSettings().Content.ImageFileTypes.InvariantContains(extension);
}
This is the source from the snippet above

In my VSIX project this error is shown on the line:
(AdapterService as IVsEditorAdaptersFactoryService).SetDataBuffer(textLines, projBuffer as IProjectionBuffer);
where textLines is created using CreateInstance method of my package
Type textLinesType = typeof(IVsTextLines);
Guid riid = textLinesType.GUID;
Guid clsid = typeof(VsTextBufferClass).GUID;
IVsTextLines textLines = (_package as Package).CreateInstance(ref clsid, ref riid, textLinesType) as IVsTextLines;
What actually is DocumentTextBuffer property and how do I set it on a newly instantiated IVsTextLines?
What I am trying to do is create a IVsTextLines to pass it as a buffer to IVsCodeWindow.
I changed the initialization of textLines to
textLines = AdapterService.CreateVsTextBufferAdapter(serviceProvider as IOleServiceProvider,
(contentTypeRegistry as IContentTypeRegistryService).GetContentType("csharp")) as IVsTextLines;
and then have used the IVsTextBuffer.InitializeContent method to initialize the Document and Data text buffer to a single space character. After that I was able to successfully use the SetBuffer method.
I am still haven't finalized my extension, so I am not sure how relevant Document Buffer's content is.
We are using Tapestry 5.4-beta-4. My problem is:
I need to keep files with locale data in an external location and under different file name then tapestry usual app.properties or pageName_locale.properties. Those files pool messages that should be then used on all pages as required (so no tapestry usual one_page-one_message_file). The files are retrieved and loaded into tapestry during application startup. Currently i am doing it like this:
#Contribute(ComponentMessagesSource.class)
public void contributeComponentMessagesSource(OrderedConfiguration<Resource> configuration, List<String> localeFiles, List<String> languages) {
for(String language: languages){
for(String fileName : localeFiles){
String localeFileName = fileName + "_" + language + ".properties";
Resource resource = new Resource(localeFileName );
configuration.add(localeFileName, resource, "before:AppCatalog");
}
}
}
The above code works in that the message object injected into pages is populated with all the messages. Unfortunatly these are only the messages that are in the default ( first on the tapestry.supported-locales list) locale. This never changes.
We want the locale to be set to the browser locale, send to the service in the header. This works for those messages passed to tapestry in the traditional way (through app.properties) but not for those set in the above code. Actually, if the browser language changes, the Messages object changes too but only those keys that were in the app.properties are assigned new values. Keys that were from external files always have the default values.
My guess is that tapestry doesn't know which keys from Messages object it should refresh (the keys from external files ale not beeing linked to any page).
Is there some way that this could be solved with us keeping the current file structure?
I think the problem is that you add the language (locale) to the file name that you contribute to ComponentMessagesSource.
For example if you contribute
example_de.properties
Tapestry tries to load
example_de_<locale>.properties
If that file does not exist, it will fall back to the original file (i.e. example_de.properties).
Instead you should contribute
example.properties
and Tapestry will add the language to the file name automatically (see MessagesSourceImpl.findBundleProperties() for actual implementation).
#Contribute(ComponentMessagesSource.class)
public void contributeComponentMessagesSource(OrderedConfiguration<Resource> configuration, List<String> localeFiles, List<String> languages) {
for(String language: languages){
for(String fileName : localeFiles){
String localeFileName = fileName + ".properties";
Resource resource = new Resource(localeFileName );
configuration.add(localeFileName, resource, "before:AppCatalog");
}
}
}
I want to move my static content to CDN. But I like (love?) T4MVC and want to keep using it. So ideally I want to just replace in production "http://mysite" to "http://cdnaddress/path". Did somebody try it? Could there be any pitfalls?
Look for ProcessVirtualPathDefault in T4MVC.tt.settings.t4:
// You can change the ProcessVirtualPath method to modify the path that gets returned to the client.
// e.g. you can prepend a domain, or append a query string:
// return "http://localhost" + path + "?foo=bar";
private static string ProcessVirtualPathDefault(string virtualPath) {
// The path that comes in starts with ~/ and must first be made absolute
string path = VirtualPathUtility.ToAbsolute(virtualPath);
// Add your own modifications here before returning the path
return path;
}
You should be able to achieve what you want by tweaking this code.
I have a site where I allow members to upload photos. In the MVC Controller I take the FormCollection as the parameter to the Action. I then read the first file as type HttpPostedFileBase. I use this to generate thumbnails. This all works fine.
In addition to allowing members to upload their own photos, I would like to use the System.Net.WebClient to import photos myself.
I am trying to generalize the method that processes the uploaded photo (file) so that it can take a general Stream object instead of the specific HttpPostedFileBase.
I am trying to base everything off of Stream since the HttpPostedFileBase has an InputStream property that contains the stream of the file and the WebClient has an OpenRead method that returns Stream.
However, by going with Stream over HttpPostedFileBase, it looks like I am loosing ContentType and ContentLength properties which I use for validating the file.
Not having worked with binary stream before, is there a way to get the ContentType and ContentLength from a Stream? Or is there a way to create a HttpPostedFileBase object using the Stream?
You're right to look at it from a raw stream perspective because then you can create one method that handles streams and therefore many scenarios from which they come.
In the file upload scenario, the stream you're acquiring is on a separate property from the content-type. Sometimes magic numbers (also a great source here) can be used to detect the data type by the stream header bytes but this might be overkill since the data is already available to you through other means (i.e. the Content-Type header, or the .ext file extension, etc).
You can measure the byte length of the stream just by virtue of reading it so you don't really need the Content-Length header: the browser just finds it useful to know what size of file to expect in advance.
If your WebClient is accessing a resource URI on the Internet, it will know the file extension like http://www.example.com/image.gif and that can be a good file type identifier.
Since the file info is already available to you, why not open up one more argument on your custom processing method to accept a content type string identifier like:
public static class Custom {
// Works with a stream from any source and a content type string indentifier.
static public void SavePicture(Stream inStream, string contentIdentifer) {
// Parse and recognize contentIdentifer to know the kind of file.
// Read the bytes of the file in the stream (while counting them).
// Write the bytes to wherever the destination is (e.g. disk)
// Example:
long totalBytesSeen = 0L;
byte[] bytes = new byte[1024]; //1K buffer to store bytes.
// Read one chunk of bytes at a time.
do
{
int num = inStream.Read(bytes, 0, 1024); // read up to 1024 bytes
// No bytes read means end of file.
if (num == 0)
break; // good bye
totalBytesSeen += num; //Actual length is accumulating.
/* Can check for "magic number" here, while reading this stream
* in the case the file extension or content-type cannot be trusted.
*/
/* Write logic here to write the byte buffer to
* disk or do what you want with them.
*/
} while (true);
}
}
Some useful filename parsing features are in the IO namespace:
using System.IO;
Use your custom method in the scenarios you mentioned like so:
From an HttpPostedFileBase instance named myPostedFile
Custom.SavePicture(myPostedFile.InputStream, myPostedFile.ContentType);
When using a WebClient instance named webClient1:
var imageFilename = "pic.gif";
var stream = webClient1.DownloadFile("http://www.example.com/images/", imageFilename)
//...
Custom.SavePicture(stream, Path.GetExtension(imageFilename));
Or even when processing a file from disk:
Custom.SavePicture(File.Open(pathToFile), Path.GetExtension(pathToFile));
Call the same custom method for any stream with a content identifer that you can parse and recognize.
i have created a resource file "Resource.resx" in my project and added some values against some keys(string values) now when i try to access the value i get the following error...
Could not find any resources appropriate for the specified culture (or the neutral culture) on disk. baseName: Resource locationInfo: fileName: Resource.resources
im accessing the resource.resx by following code
string key = "Home";
string resourceValue = string.Empty;
string resourceFile = "Resource";//name of my resource file Resource.resx
string filePath =System.AppDomain.CurrentDomain.BaseDirectory.ToString();
ResourceManager resourceManager = ResourceManager.CreateFileBasedResourceManager(resourceFile, filePath, null);
resourceValue = resourceManager.GetString(key);
im using mvc.net...
plz help
Why don't you use the class automatically generated by Visual Studio when you added the Resource.resx file (Resource.Designer.cs). This way you don't need to write all the code you wrote.
// assuming you've added a Home key in the resource file
string resourceValue = Resource.Home;
