I'm tring to get the profile picture from People App. I used
Windows.ApplicationModel.Contacts.Contact contact = new Contact();
I got Thumbnail from propety contact.Thumbnail.
I need to convert this Thumbnail to StorageFile. Could you please give inputs to solve this issue?
And, while using the following code:
IRandomAccessStreamWithContentType stream = awaitcontactInfo.Thumbnail.OpenReadAsync();
if(stream != null && stream.Size > 0)
{
//
}
Sometimes I'm getting RPC Server is unavailable Exception. Sometimes the streamSize is Zero.
You are creating new instance of Contact class. You don't have to do that to pick contact from people. You should use ContactPicker.
var contactPicker = new Windows.ApplicationModel.Contacts.ContactPicker();
contactPicker.CommitButtonText = "Select";
ContactInformation contact = await contactPicker.PickSingleContactAsync();
if (contact != null)
{
IRandomAccessStreamWithContentType stream = await contact.GetThumbnailAsync();
if (stream != null && stream.Size > 0)
{
var file = await ApplicationData.Current.TemporaryFolder.CreateFileAsync("MyContactThumb.png", CreationCollisionOption.GenerateUniqueName);
// You can also use FileSavePicker to save file in user defined location.
Windows.Storage.Streams.Buffer MyBuffer = new Windows.Storage.Streams.Buffer(Convert.ToUInt32(stream.Size));
IBuffer iBuf = await stream.ReadAsync(MyBuffer, MyBuffer.Capacity, InputStreamOptions.None);
await FileIO.WriteBufferAsync(file, iBuf);
}
}

I am trying to send image to the API, I have multiple local storage image path which is stored in local
database sqlite and I have to upload these image on one click. in the
local database. replace _mediaFile = await CrossMedia.Current.TakePhotoAsync
with _mediaFile = Image_Path_From_Database
The datatobesync it contain multiple local storage image path from local dat
conn = await DependencyService.Get().GetConnection();
List datatobesync = new List();
datatobesync = (from c in conn.Table<CDCInfo>()
where c.SyncStatus == 0 && c.UserName == Settings.Username
select new CDCInfo
{
PhotoPath = c.PhotoPath,
}
I have a string image path but I am not sure about how
to use this
Using MediaPlugin for opening a gallery or camera. After selecting the
picture I set that picture to _mediafile and added to the content and send it to the API.
Detail Here
these lines of code gets image from the gallery or camra (using MediaPlugin) in a
mediaFile and send it to the API
private MediaFile _mediaFile;
_mediaFile = await CrossMedia.Current.TakePhotoAsync(new Plugin.Media.Abstractions.
StoreCameraMediaOptions
{
Directory = "Sample",
Name = "test.jpg",
AllowCropping = true,
PhotoSize = PhotoSize.Medium
});
var content = new MultipartFormDataContent();
content.Add(new StreamContent(_mediaFile.GetStream()),"\"Files\"", $"\"{_mediaFile.path}\"");
var httpClnt = new HttpClient();
result = await httpClnt.PostAsync(Urle, content);
How can I add image to the content using database path and send it to the API without using MediaPlugin.
I am trying to do something like
foreach (var item in datatobesync)
{
try
{
HttpClient client = new HttpClient();
MultipartFormDataContent content = new
MultipartFormDataContent();
content.Add(new
StreamContent("Here I want to user item.PhotoPath Image path from the database".GetStream()),"\"Files\"",
$"\"{item.PhotoPath}\"");
var httpClnt = new HttpClient();
result = await httpClnt.PostAsync(Urle, content);
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}
}
I dont know how to use image path at this line
content.Add(new StreamContent(How_to_User_ImagePath_Her.GetStream()),"\"Files\"",
$"\"{item.PhotoPath}\"");
How to get GetStram() of image path

I am trying to read a file in my Windows 8 Store App. Here is a fragment of code I use to achieve this:
if(file != null)
{
var stream = await file.OpenAsync(FileAccessMode.Read);
var size = stream.Size;
using(var inputStream = stream.GetInputStreamAt(0))
{
DataReader dataReader = new DataReader(inputStream);
uint numbytes = await dataReader.LoadAsync((uint)size);
string text = dataReader.ReadString(numbytes);
}
}
However, an exeption is thrown at line:
string text = dataReader.ReadString(numbytes);
Exeption message:
No mapping for the Unicode character exists in the target multi-byte code page.
How do I get by this?
I managed to read file correctly using similar approach to suggested by duDE:
if(file != null)
{
IBuffer buffer = await FileIO.ReadBufferAsync(file);
DataReader reader = DataReader.FromBuffer(buffer);
byte[] fileContent = new byte[reader.UnconsumedBufferLength];
reader.ReadBytes(fileContent);
string text = Encoding.UTF8.GetString(fileContent, 0, fileContent.Length);
}
Can somebody please elaborate, why my initial approach didn't work?
Try this instead of string text = dataReader.ReadString(numbytes):
dataReader.ReadBytes(stream);
string text = Convert.ToBase64String(stream);
If, like me, this was the top result when search for the same error regarding UWP, see the below:
The code I had which was throwing the error (no mapping for the unicode character exists..):
var storageFile = await Windows.Storage.AccessCache.StorageApplicationPermissions.FutureAccessList.GetFileAsync(fileToken);
using (var stream = await storageFile.OpenAsync(FileAccessMode.Read))
{
using (var dataReader = new DataReader(stream))
{
await dataReader.LoadAsync((uint)stream.Size);
var json = dataReader.ReadString((uint)stream.Size);
return JsonConvert.DeserializeObject<T>(json);
}
}
What I changed it to so that it works correctly
var storageFile = await Windows.Storage.AccessCache.StorageApplicationPermissions.FutureAccessList.GetFileAsync(fileToken);
using (var stream = await storageFile.OpenAsync(FileAccessMode.Read))
{
T data = default(T);
using (StreamReader astream = new StreamReader(stream.AsStreamForRead()))
using (JsonTextReader reader = new JsonTextReader(astream))
{
JsonSerializer serializer = new JsonSerializer();
data = (T)serializer.Deserialize(reader, typeof(T));
}
return data;
}
Ok, so I am writing a service to recieve file uploads from an iPhone application through phonegap. They send me a file and I am trying to grab the actual file without saving it to any type of file system. Currently this is what I have
[HttpPost]
public string processRequest()
{
string ext = "Entered";
Request.Content.ReadAsMultipartAsync<MultipartMemoryStreamProvider>(new MultipartMemoryStreamProvider()).ContinueWith((tsk) =>
{
ext = "Request";
MultipartMemoryStreamProvider prvdr = tsk.Result;
foreach (HttpContent ctnt in prvdr.Contents)
{
ext = "Foreach";
// You would get hold of the inner memory stream here
Stream stream = ctnt.ReadAsStreamAsync().Result;
if (stream == null)
{
ext = "Null Stream";
}
Image img = Image.FromStream(stream);
if (ImageFormat.Jpeg.Equals(img.RawFormat))
{
ext = "jpeg";
}
else if (ImageFormat.Png.Equals(img.RawFormat))
{
ext = "Png";
}
else if (ImageFormat.Gif.Equals(img.RawFormat))
{
ext = "Gif";
}
// do something witht his stream now
}
});
return ext;
}
I have put various responses in there so I can see where the function is getting to. Right now it always returns "Entered" which means its not even reading the content of the request, the end game is for me to grab the file object, convert it into an image and then to base 64. Any direction would be appreciated. Remember I want to do this without any file system so no solutions that involve mapping a path to a server folder.
Ok so a little update, I have edited my code according to my first response and at least it attempts to execute now but it just gets infinitely stuck inside the code. This happens during the ReadAsMultipartAsync function
[HttpPost]
public string processRequest()
{
string ext = "Entered";
Request.Content.ReadAsMultipartAsync(new MultipartMemoryStreamProvider()).ContinueWith((tsk) =>
{
ext = "Request";
MultipartMemoryStreamProvider prvdr = tsk.Result;
foreach (HttpContent ctnt in prvdr.Contents)
{
ext = "Foreach";
// You would get hold of the inner memory stream here
Stream stream = ctnt.ReadAsStreamAsync().Result;
if (stream == null)
{
ext = "Null Stream";
}
Image img = Image.FromStream(stream);
if (ImageFormat.Jpeg.Equals(img.RawFormat))
{
ext = "jpeg";
}
else if (ImageFormat.Png.Equals(img.RawFormat))
{
ext = "Png";
}
else if (ImageFormat.Gif.Equals(img.RawFormat))
{
ext = "Gif";
}
// do something witht his stream now
}
}).Wait();
return ext;
}
The block inside ContinueWith also runs asynchronously (if you look at the signature for ContinueWith, you'll see that it returns a Task as well). So, with the above code, essentially you're returning before any of that has a chance to execute.
Try doing:
Request.Content.ReadAsMultipartAsync().ContinueWith(...).Wait();
Also, not sure you need to go to the trouble of doing Request.Content.ReadAsMultipartAsync<MultipartMemoryStreamProvider>(new MultipartMemoryStreamProvider()); I believe Request.Content.ReadAsMultipartAsync() should suffice.
Hope that helps!
I am using TweetSharp in a Windows Phone project and no matter what I do, I can't post a tweet with media.
I am getting the exception 195: Missing or invalid parameter.
I read that usually this can be a cause of invalid data, like the stream that I provide is invalid.
I have tried other way but nothing works , I get the same exception ...
The sharing code, simplified is like this:
MediaLibrary library = new MediaLibrary();
var picture = library.Pictures[0];
var options = new SendTweetWithMediaOptions
{
Images = new Dictionary<string, Stream> { { picture.Name, picture.GetImage() } },
Status = TweetTextBox.Text,
};
AutentificateTwitterService().SendTweetWithMedia(options, (status, response) =>
_dispatcher.BeginInvoke(() =>
{
DonePosting();
if (response.StatusCode == HttpStatusCode.OK)
{
_lastPostId = status.Id;
}
else
{
MessageBox.Show(String.Format(
"There was an error sending image to Twitter{0}{1}",
Environment.NewLine,
response.Error));
}
}));
I tried sharing with linqtotwitter and worked but TweetSharp is more appropriate for my project.
Finally after some time I've found the problem to this and I am sure to other more WP and SendTweetWithMediaOptions related problems.
The thing is that if you dig into SendTweetWithMedia the way it is now you will get to TwitterService.cs where WithHammock will be called, is just the images are not passed as parrameters, so they get lost right there :)
I did fix this passing the parameters and adding
private void WithHammock<T>(WebMethod method, Action<T, TwitterResponse> action, string path, IDictionary<string, Stream> files, params object[] segments) where T : class
{
var url = ResolveUrlSegments(path, segments.ToList());
var request = PrepareHammockQuery(url);
request.Method = method;
request.QueryHandling = QueryHandling.AppendToParameters;
foreach (var file in files)
{
request.AddFile("media[]", file.Key, file.Value);
}
WithHammockImpl(request, action);
}
I will try and see if I can Pull this so that everyone else can have this fix.
Hope this helps.
