As far as i know, i can youse Actions (http://blog.botframework.com/2016/05/13/BotFramework.buttons/) to create inline keyboards in Telegram and other messages.
But what about Custom Keyboards (https://core.telegram.org/bots#keyboards)? How can i add them using Bot Framework?
I read about ChannelData (http://docs.botframework.com/connector/custom-channeldata/#custom-telegram-messages), but i didnt get, how can i pass JSON to CreateReplyMessage method.
Use CreateReplyMessage to create a Message object:
var replyMessage = incomingMessage.CreateReplyMessage("Yo, I heard you.");
Then set the ChannelData
replyMessage.ChannelData = {custom Telegram JSON}
For Bot Framework v4:
{
var reply = context.Context.Activity.CreateReply(messageText);
if (BotDialogHelpers.ExtractMessengerFromDialogContext(context) == BotDialogHelpers.Messengers.Telegram)
{
GenerateReplyMarkupForTelegram(reply);
}
await context.Context.SendActivityAsync(reply, token);
}

I'm trying to send an HTTP request from .NET Core 3.1 REST API to another API but below Exception keep appeared Although I'm already added the Authentication Key :
The request was missing an Authentication Key. Please, refer to section "Authentication"
here is my code :
public class AppService
{
private readonly IHttpClientFactory _clientFactory;
string key = "key=llllll ......";
string webAPIKey = "......";
string Id = "......";
public AppService(IHttpClientFactory clientFactory) {
_clientFactory = clientFactory;
}
public async Task<string> sendBroadCastNotification()
{
Data _data = new Data();
_data.title = "test data Ttile";
_data.detail = "test data detail";
Notification _notification = new Notification();
_notification.title = "test notification Ttile";
_notification.body = "test notification body";
MyNotification NotifcationData = new MyNotification {
data=_data,
notification=_notification,
to= "/topics/all"
};
try {
var client = _clientFactory.CreateClient();
client.DefaultRequestHeaders.Add("project_id", Id );
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Authorization", key);
StringContent bodyOfRequest = new StringContent(System.Text.Json.JsonSerializer.Serialize(NotifcationData ), Encoding.UTF8, "application/json");
using var httpResponse =
await client.PostAsync("https://.......", bodyOfRequest);
var result = httpResponse.Content.ReadAsStringAsync().Result;
return result;
}
catch (Exception ex)
{
throw new System.ArgumentException(ex.Message.ToString(), "original");
}
//return null;
}
}
I found the answer here in this link:
I add the key by using the below line:
client.DefaultRequestHeaders.TryAddWithoutValidation("Authorization", key);
the below way that I was trying to add the authorization header wasn't understandable as an authorization header :
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Authorization", key);
I can save a picture in iOS and Android but I can't find a way to save an image in UWP. Any ideas?
Thank you in advance.
I can't find a way to save an image in UWP
No, we can't extract the image data from an Xamarin ImageSource object.
There is StreamImagesourceHandler class implementation in UWP, see here
public sealed class StreamImageSourceHandler : IImageSourceHandler
{
public async Task<Windows.UI.Xaml.Media.ImageSource> LoadImageAsync(ImageSource imagesource, CancellationToken cancellationToken = new CancellationToken())
{
BitmapImage bitmapimage = null;
//Omitted
return bitmapimage;
}
}
So we need to extract data from BitmapImage.
Actually the BitmapImage class is inherited from ImageSource class, while we can't extract the image data from ImageSource, for the reason, please see these two questions:
Convert ImageSource to WriteableBitmap in Metro Windows 8
How save BitmapImage WinRT
The solution here is to use different way for Windows Runtime(W/WP8.1 & UWP) app, extracting image data from System.IO.Stream class is supported in UWP.
We can use DependencyService to access native platform features, firstly, create an interface in PCL:
public interface ISaveImage
{
void SavePictureToDisk(ImageSource imgSrc, string Id, bool OverwriteIfExist = false);
void SavePictureToDiskWINRT(System.IO.Stream imgStream, string Id, bool OverwriteIfExist = false);
}
In the code behind of Xamarin page:
var memoryStream = new MemoryStream(Convert.FromBase64String("iVBOxxxxxxxxxxMVEX/uQOAuwPzUxxxxxxxxxxxx="));
ImageSource imgsource = ImageSource.FromStream(() => memoryStream);
if (Device.OS == TargetPlatform.Windows|| Device.OS == TargetPlatform.WinPhone)
DependencyService.Get<ISaveImage>().SavePictureToDiskWINRT(memoryStream, "1");
else
DependencyService.Get<ISaveImage>().SavePictureToDisk(imgsource, "1");
Implement the interface in UWP platform:
using Xamarin.Forms;
using WorkingWithImages.WinUniversal;
using System.IO;
using System;
using Windows.Storage.Streams;
[assembly: Xamarin.Forms.Dependency(typeof(SaveImageImplementation))]
namespace WorkingWithImages.WinUniversal
{
public class SaveImageImplementation : ISaveImage
{
public SaveImageImplementation() { }
public void SavePictureToDisk(ImageSource imgSrc, string Id, bool OverwriteIfExist = false)
{
throw new NotImplementedException();
}
public async void SavePictureToDiskWINRT(Stream imgStream, string Id, bool OverwriteIfExist = false)
{
var inStream = imgStream.AsRandomAccessStream();
var fileBytes = new byte[inStream.Size];
using (DataReader reader = new DataReader(inStream))
{
await reader.LoadAsync((uint)inStream.Size);
reader.ReadBytes(fileBytes);
}
var file = await Windows.Storage.ApplicationData.Current.LocalFolder.CreateFileAsync(Id+".jpg", Windows.Storage.CreationCollisionOption.ReplaceExisting);
using (var fs = await file.OpenAsync(Windows.Storage.FileAccessMode.ReadWrite))
{
var outStream = fs.GetOutputStreamAt(0);
var dataWriter = new DataWriter(outStream);
dataWriter.WriteBytes(fileBytes);
await dataWriter.StoreAsync();
dataWriter.DetachStream();
await outStream.FlushAsync();
outStream.Dispose();
fs.Dispose();
}
}
}
}
Please check my completed demo in here
About UWP File storage guidance, please see Create, write, and read a file
maybe someone needs a solution for iOS and Android (below). Meanwhile I'm waiting an idea for UWP.

public async void SaveImage(ImageSource imgSrc, string id, bool overwriteIfExist = false)
{
var renderer = new StreamImagesourceHandler();
var photo = await renderer.LoadImageAsync(imgSrc);
string jpgFilename = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Personal), id + ".jpg");
if (File.Exists(jpgFilename))
{
File.Delete(jpgFilename);
}
NSData imgData = photo.AsJPEG();
NSError err;

{
Console.WriteLine("saved as " + jpgFilename);
}
else

Good to know, when iOS saves an image as jpg, the image header says png.

How can I get channel messages from telegram channels with TLSharp?
The following links haven't helped me:
How can I get messages from a Telegram channel with the Telegram API
How to obtain all messages from my channel in telegram?
You can use this code
public async Task GatherChannelHistory(string channelName, int offset = 0, int maxId = -1, int limit = 50)
{
_resultMessages.Clear();
await _client.ConnectAsync();
var dialogs = (TLDialogsSlice)await _client.GetUserDialogsAsync();
var chat = dialogs.Chats.ToList()
.OfType<TLChannel>()
.FirstOrDefault(c => c.Title == channelName);
if (chat.AccessHash != null)
{
var tlAbsMessages =
await _client.GetHistoryAsync(
new TLInputPeerChannel {ChannelId= chat.Id, AccessHash = chat.AccessHash.Value}, offset,
maxId, limit);
var tlChannelMessages = (TLChannelMessages) tlAbsMessages;
for (var index = 0; index < tlChannelMessages.Messages.Count-1; index++)
{
var tlAbsMessage = tlChannelMessages.Messages.ToList()[index];
var message = (TLMessage) tlAbsMessage;
//Now you have the message and you can do what you need with it
//the code below is an example of messages classification
if (message.media == null)
{
_resultMessages.Add(new ChannelMessage()
{
Id = message.id,
ChannelId = chat.id,
Content = message.message,
Type = EnChannelMessage.Message,
Views = message.views,
});
}
else
{
switch (message.media.GetType().ToString())
{
case "TeleSharp.TL.TLMessageMediaPhoto":
var tLMessageMediaPhoto = (TLMessageMediaPhoto)message.media;
_resultMessages.Add(new ChannelMessage()
{
Id = message.id,
ChannelId = chat.id,
Content = tLMessageMediaPhoto.caption,
Type = EnChannelMessage.MediaPhoto,
Views = message.views ?? 0,
});
break;
case "TeleSharp.TL.TLMessageMediaDocument":
var tLMessageMediaDocument = (TLMessageMediaDocument)message.media;
_resultMessages.Add(new ChannelMessage()
{
Id = message.id,
ChannelId = chat.id,
Content = tLMessageMediaDocument.caption,
Type = EnChannelMessage.MediaDocument,
Views = message.views ?? 0,
});
break;
case "TeleSharp.TL.TLMessageMediaWebPage":
var tLMessageMediaWebPage = (TLMessageMediaWebPage)message.media;
string url = string.Empty;
if (tLMessageMediaWebPage.webpage.GetType().ToString() != "TeleSharp.TL.TLWebPageEmpty")
{
var webPage = (TLWebPage) tLMessageMediaWebPage.webpage;
url = webPage.url;
}
_resultMessages.Add(new ChannelMessage
{
Id = message.id,
ChannelId = chat.id,
Content = message.message + #" : " + url,
Type = EnChannelMessage.WebPage,
Views = message.views ?? 0,
});
break;
}
}
}
}
}
To get channel messages you simply need to be receiving channel updates.
As at TL-schema-52 you could request:
channels.getDialogs#a9d3d249 offset:int limit:int = messages.Dialogs;
however this has been dropped in TL-schema-53.
I'm guessing you can try one of the other channel.* functions,
I have not tried yet on TL-schema-53
What version of the TL-schema is your TLSharp using?
You could simply implement the relevant functions if they are not yet implemented in your TLSharp version

I am using ASP.NET MVC 6 Web API. In the View I use free-jqgrid.
Let's borrow Oleg's free jqgrid data to demonstrate my purpose. We already have the table shown.
Next I am going to add new Vendor. Please notify that there is primary key id(identity column) in the database. We don't want it displaying in the screen.
In VendorRespository.cs, I add the new Vendor as
public void AddVendor(Vendor item)
{
using (VendorDataContext dataContext = new VendorDataContext())
{
dataContext.Database.Connection.ConnectionString = DBUtility.GetSharedConnectionString(
"http://centralized.admin.test.com");
var newVendor = dataContext.Vendors.Create();
newVendor.Company = item.Company;
newVendor.ContactName = item.ContactName;
newVendor.ContactPhone = item.ContactName;
newVendor.UserName = item.UserName;
newVendor.UserKey = item.UserKey;
newVendor.Active = item.Active;
newVendor.FacilityId =item.FacilityId;
newVendor.ClientID = item.ClientID;
dataContext.SaveChanges();
}
}
My questions:
Not sure the script like?
<script>
API_URL = "/VendorManagement/";
function updateDialog(action) {
return {
url: API_URL
, closeAfterAdd: true
, closeAfterEdit: true
, afterShowForm: function (formId) { }
, modal: true
, onclickSubmit: function (params) {
var list = $("#jqgrid");
var selectedRow = list.getGridParam("selrow");
rowData = list.getRowData(selectedRow);
params.url += rowData.Id;
params.mtype = action;
}
, width: "300"
};
}
jQuery("#jqgrid").jqGrid('navGrid',
{ add: true, edit: true, del: true },
updateDialog('PUT'),
updateDialog('POST'),
updateDialog('DELETE')
);
In the controller, not sure what is the code?
// POST
public HttpResponseMessage PostVendor(Vendor item)
{
_vendorRespository.AddVendor(item);
var response = Request.CreateResponse<Vendor>(HttpStatusCode.Created, item);
string uri = Url.Link("DefaultApi", new { id = item.Id });
response.Headers.Location = new Uri(uri);
return response;
}
My code has many compiling errors such as
'HttpRequest' does not contain a definition for 'CreateResponse' and the best extension method overload 'HttpRequestMessageExtensions.CreateResponse(HttpRequestMessage, HttpStatusCode, Vendor)' requires a receiver of type 'HttpRequestMessage'
Please help me to get rid of the error and inappropriate code.
EDIT:
I borrowed the code snippet from here.
I need add the code such as
[Microsoft.AspNet.Mvc.HttpGet]
public dynamic GetVendorById(int pkey)
{
return null;
}
And
// POST
[System.Web.Http.HttpPost]
public HttpResponseMessage PostVendor(Vendor item)
{
_vendorRespository.AddVendor(item);
var response = Request.CreateResponse<Vendor>(HttpStatusCode.Created, item);
string uri = Url.Link("/VendorManagement/GetVendorById", new { id = item.pkey });
response.Headers.Location = new Uri(uri);
return response;
}
I am trying add a subscriber to a list but I'm struggling to implement it without any example code.
can anybody help me with the example?
Inspired by this video:
MailChimp.NET Tutorial: Create, Edit And Delete List Members - here my test code to add a subscriber to a 'given list'.
The subscriber will receive an email asking to confirm the subscription. After that confirmation the new subscriber
will be listed in mailchimp campaign list.
(used version mailchimp.net wrapper v:3 with newtonsoft.json version 10.0.3) - this worked for me.
private static readonly IMailChimpManager Manager = new MailChimpManager(ApiKey);
public async Task AddSubscriberToCampaignList(string emailAddress, string listName, string fname, string lname)
{
try
{
var listsAwaitable = Manager.Lists.GetAllAsync().ConfigureAwait(false);
var list = listsAwaitable.GetAwaiter().GetResult().FirstOrDefault(l =>
l.Name.Equals(listName, StringComparison.CurrentCultureIgnoreCase));
if (list != null)
{
//the subscriber
var member = new Member
{
EmailAddress = emailAddress,
StatusIfNew = Status.Pending,
EmailType = "html",
TimestampSignup = DateTime.UtcNow.ToString("s"),
};
if (fname != null && lname != null)
{
var subscriberName = new Dictionary<string, object>
{
{"FNAME", fname},
{"LNAME", lname}
};
member.MergeFields = subscriberName;
}
string campaignListKey = list.Id;
await Manager.Members.AddOrUpdateAsync(campaignListKey, member);
}
}
catch (MailChimpException e)
{
throw;
}
