I'm trying to upload photos into Facebook by using MVC3 C#. The code is running successfully but the photos are not uploaded into Facebook. I'm having add ID and App Secret. I tried many ways and for many days I worked hard, but the result is zero. Here is the code of my controller
[HttpPost][HttpGet]
public ActionResult Profile(HttpPostedFileBase file, FacebookOAuthResult facebookOAuthResult) {
dynamic args = new ExpandoObject();
args = new Dictionary<string, object>();
args["message"] = "hi";
args["picture"] = "http://apps.facebook.com/Uploads/photos";
string accesstoken=FacebookWebContext.Current.AccessToken;
FacebookClient fbApp = new FacebookClient(accesstoken);
try {
fbApp.Post("MYAPPID" + "/Photos", args);
} catch (FacebookOAuthException ex) {
//
}
// Verify that the user selected a file
if (file != null && file.ContentLength > 0) {
var path1 = Path.Combine(Server.MapPath("~/Content/uppoads"), file.FileName);
//file.SaveAs(path1);
fbApp.Post("MYAPPID" + "/photos", path1);
}
// redirect back to the index action to show the form once again
return RedirectToAction("Profile");
}
Could anyone help me to find the solution? Thanks in advance.
You are Post the local path of the photo to Facebook, FB doesn't know what it is.
You should post the photo as binary in the Post body.
var media = new Facebook.FacebookMediaObject();
var filebytes = System.IO.File.ReadAllBytes(path1);
media.SetValue(filebytes);
fbApp.Post("248050331932489" + "/photos", media);

I need to check current version of Installed Application and Playstore application version. If it is not same app should navigate to Playstore .
im using xam.Plugin.LatestVersion(2.1.0) To get the latestversion number of application from play console. unfortunately not getting latest version number of application from play store. The below code im using.
private async void ChekAppVersion()
{
try
{
latestVersionNumber = await CrossLatestVersion.Current.GetLatestVersionNumber();
installedVersionNumber = CrossLatestVersion.Current.InstalledVersionNumber;
if (installedVersionNumber != latestVersionNumber)
{
await DisplayAlert("New Version", "There is a new version of this app available. Please update now?", "Ok");
await CrossLatestVersion.Current.OpenAppInStore();
ChekAppVersion();
}
else
{
}
}
catch (Exception ex)
{
}
}
Im getting the installedVersionNumber, but im unable to get the latestVersionNumber(Playstore).
Please help on this.
They have removed the version from div, now it's displayed with js, but data is still there inside a <script> tag. My current fixed code is:
private bool _lockCheckUpdates;
public async Task<bool> CheckNeedUpdate()
{
if (Connectivity.NetworkAccess != NetworkAccess.Internet || _lockCheckUpdates)
return false;
_lockCheckUpdates = true;
try
{
HttpClient myClient = CreateClient();
if (Device.RuntimePlatform == Device.Android)
{
var bundle = "com.todo.app"; //ANDROID BUNDLE NAME HERE
string url = $"https://play.google.com/store/apps/details?id={bundle}&hl=en";
string raw = await myClient.GetStringAsync(new Uri(url));
var doc = new HtmlDocument();
doc.LoadHtml(raw);
var scripts = doc.DocumentNode.Descendants()
.Where(n => n.Name == "script" && n.InnerText.Contains("AF_initDataCallback({key: 'ds:4'"))
.ToArray();
var script = scripts.First().InnerText;
var engine = new Jurassic.ScriptEngine();
var eval = "(function() { var AF_initDataCallback = function(p) { return p.data[1][2][140][0][0][0]; }; return " + script + " })()";
var result = engine.Evaluate(eval);
//var json = JSONObject.Stringify(engine, result); //for debug, check in browser console with JSON.parse(json)
var remote = $"{result}".ToDouble();
var local = App.Version.ToDouble();
return local < remote;
}
else if (Device.RuntimePlatform == Device.iOS)
{
var bundle = "com.todo.app";//iOS BUNDLE NAME HERE
string url = $"http://itunes.apple.com/lookup?bundleId={bundle}";
string raw = await myClient.GetStringAsync(new Uri(url));
var dto = JsonConvert.DeserializeObject<AppStoreRecord>(raw);
double local = App.Version.ToDouble();
if (dto.ResultCount > 0)
{
double remote = dto.Results[0].Version.ToDouble();
return remote > local;
}
}
}
catch (Exception e)
{
Logger.Error("CheckNeedUpdate", e);
}
finally
{
_lockCheckUpdates = false;
}
return false;
}
Using nugets
Jurassic to evaluate the script on page,
HtmlAgilityPack to parse html,
Xamarin.Essentials to check if we are online,
and AppoMobi.Specials for .ToDouble() etc
I hope this could also be useful to fix https://github.com/edsnider/latestversionplugin/issues/43 :)
The plugin you are using no longer works for Android https://github.com/edsnider/latestversionplugin/issues/43
You will need to find a new way to get the desired information.
PR has been made on this plugin... it works again ;-)
I am saving my records using this code:
string path = Android.OS.Environment.ExternalStorageDirectory.AbsolutePath;
public string fileName { get; set; }
fileName = Path.Combine(path, "sample.wav");
if (!recorder.IsRecording)
{
recorder.StopRecordingOnSilence = TimeoutSwitch.IsToggled;
//Start recording
var audioRecordTask = await recorder.StartRecording();
BtnDoneRec.IsEnabled = false;
await audioRecordTask;
RecEditor.IsEnabled = true;
BtnDoneRec.IsEnabled = false;
PlayButton.IsEnabled = true;
var filePath = recorder.GetAudioFilePath();
if (filePath != null)
{
var stream = recorder.GetAudioFileStream();
using (var fileStream = new FileStream(fileName, FileMode.Create, FileAccess.Write))
{
stream.CopyTo(fileStream);
}
}
}
else
{
//stop recording ...
await recorder.StopRecording();
}
I want my record to have a specific name which is labeled with my RecEditor
using (var streamReader = new StreamReader(fileName))
{
File.Move("sample.wav", RecEditor.Text + ".wav");
}
So it will rename "sample.wav" to "RecEditor text.wav" every time I click my save button.
But when I click save, it gives me this record
System.IO.FileNotFoundException: 'Could not find file '/sample.wav'.'
The record is stored in /storage/emulated/0/sample.wav
The sample.wav is created in my device but I don't know why it give me 'Could not find file '/sample.wav'.' error. What am i doing wrong here?
I believe that what you're looking is something like this:
if(File.Exists(fileName))
{
var newFileName = Path.Combine(path, $"{RecEditor.Text}.wav");
File.Move(fileName, newFileName);
}
You don't need to open a new Stream as you are doing. Also, you need to put the full file path not only the file name.
You might want to validate that RecEditor.Text is not empty before using its value for the newfileName
Hope this helps.-
This is a followup to my previous question: Xamarin.Forms App return data to calling App
That works perfectly and I can share images to anywhere, except to Facebook comments. When I click the camera on the content box the app can be selected, I can select the image, Set result and Finish are called, and the app closes and it sends data to Facebook, and then however I then get the error : The image could not be uploaded, try again?
I can't find any fundamental differences between posting to a status or a comment, so I'm guessing it's subtle. Any thoughts on how I can change my intent to post properly?
Adding for completeness:
Bitmap b = null;
string url;
if (!string.IsNullOrEmpty(this.saleItems[i].ImageUrl))
{
url = this.saleItems[i].ImageUrl;
}
else
{
url = await FileHelper.GetLocalFilePathAsync(this.saleItems[i].Id);
}
//download
using (var webClient = new WebClient())
{
var imageBytes = webClient.DownloadData(url);
if (imageBytes != null && imageBytes.Length > 0)
{
b = BitmapFactory.DecodeByteArray(imageBytes, 0, imageBytes.Length);
}
}
//set local path
var tempFilename = "test.png";
var sdCardPath = Android.OS.Environment.ExternalStorageDirectory.AbsolutePath;
var filePath = System.IO.Path.Combine(sdCardPath, tempFilename);
using (var os = new FileStream(filePath, FileMode.Create))
{
b.Compress(Bitmap.CompressFormat.Png, 100, os);
}
b.Dispose();
var imageUri = Android.Net.Uri.Parse($"file://{sdCardPath}/{tempFilename}");
var sharingIntent = new Intent();
sharingIntent.SetAction(Intent.ActionSend);
sharingIntent.SetType("image/*");
sharingIntent.PutExtra(Intent.ExtraText, "some txt content");
sharingIntent.PutExtra(Intent.ExtraStream, imageUri);
sharingIntent.AddFlags(ActivityFlags.GrantReadUriPermission);
//await SaleItemDataService.Instance.BuySaleItemAsync(this.saleItem);
SetResult(Result.Ok, sharingIntent);
Finish();
Use below:
Intent sharingIntent = new Intent();
string imageUri = "file://" + requestedUri;
sharingIntent.SetData(Android.Net.Uri.Parse(imageUri));
I have a custom comment activity which I'm updating in code and this used to work but has started failing recently. It creates the activity but when I try to retrieve it or execute SetStateResponse on it, I get "tk_comment With Id = 9a1686d1-7d9d-e611-80e3-00155d001104 Does Not Exist" - which doesn't make sense as I've just created it! The activity record shows up against the account but I can't click on it there or do anything (Record is unavailable - The requested record was not found or you do not have sufficient permissions to view it.).
This is the code I'm using. I'd love you to tell me I've made some simple mistake :)
using (_serviceProxy = ServerConnection.GetOrganizationProxy(serverConfig))
{
_serviceProxy.EnableProxyTypes();
try
{
tk_comment comment = new tk_comment();
int maxLength = 190; //subject has a max length of 200 characters
if (subject.Length > maxLength)
{
comment.Subject = subject.Substring(0, maxLength);
comment.Description = subject.Substring(maxLength, subject.Length - maxLength);
}
else
{
comment.Subject = subject;
}
comment.RegardingObjectId = entity.ToEntityReference();
comment.ActualStart = CommentDate;
comment.ActualEnd = CommentDate;
comment.ScheduledStart = CommentDate;
comment.ScheduledEnd = CommentDate;
Guid commentID = _serviceProxy.Create(comment);
try
{
tk_comment aComment = (tk_comment)_serviceProxy.Retrieve(tk_comment.EntityLogicalName, commentID, new ColumnSet(allColumns: true));
}
catch (Exception ex)
{
SingletonLogger.Instance.Error("Always an error here " + ex.Message);
}
Account test = (Account) _serviceProxy.Retrieve(Account.EntityLogicalName, entity.Id, new ColumnSet(allColumns: true));
// tk_comment newComment = (tk_comment)_serviceProxy.Retrieve(tk_comment.EntityLogicalName, commentID, new ColumnSet(allColumns: true));
SetStateRequest request = new SetStateRequest();
request.EntityMoniker = new EntityReference(tk_comment.EntityLogicalName, commentID);
request.State = new OptionSetValue((int) tk_commentState.Completed); //completed
request.Status = new OptionSetValue(2); //completed
SetStateResponse response = (SetStateResponse)_serviceProxy.Execute(request); //always an error here too
}
Appreciate any suggestions
Cheers, Mick
It seems like you don't have proper read permission of this custom activity entity.
OR You need to validate all the permissions of this custom entity.
What is the best way to resize an uploaded image in MVC 6? I'd like to store multiple variants of an image (such as small, large, etc.) to be able to choose which to display later.
Here's my code for the action.
[HttpPost]
public async Task<IActionResult> UploadPhoto()
{
if (Request.Form.Files.Count != 1)
return new HttpStatusCodeResult((int)HttpStatusCode.BadRequest);
IFormFile file = Request.Form.Files[0];
// calculate hash
var sha = System.Security.Cryptography.SHA256.Create();
byte[] hash = sha.ComputeHash(file.OpenReadStream());
// calculate name and patch where to store the file
string extention = ExtentionFromContentType(file.ContentType);
if (String.IsNullOrEmpty(extention))
return HttpBadRequest("File type not supported");
string name = WebEncoders.Base64UrlEncode(hash) + extention;
string path = "uploads/photo/" + name;
// save the file
await file.SaveAsAsync(this.HostingEnvironment.MapPath(path));
}
I would suggest using Image Processor library.
http://imageprocessor.org/imageprocessor/
Then you can just do something along the lines of:
using (var imageFactory = new ImageFactory())
using (var fileStream = new FileStream(path))
{
file.Value.Seek(0, SeekOrigin.Begin);
imageFactory.FixGamma = false;
imageFactory.Load(file.Value)
.Resize(new ResizeLayer(new Size(264, 176)))
.Format(new JpegFormat
{
Quality = 100
})
.Quality(100)
.Save(fileStream);
}
Where file.Value is your file that was uploaded (the stream) (I don't know what it is in MVC, this is code I use in a Nancy project)
