I was trying the multi-language chat bot in bot framework. https://github.com/Microsoft/BotBuilder-Samples/tree/master/samples/csharp_dotnetcore/17.multilingual-bot.
I was successful in translating ordinary message with no attachment. But I'm having a problem with attachment like herocard or suggestedcard.
var reply = stepContext.Context.Activity.CreateReply();
var card = new HeroCard();
card.Buttons = new List<CardAction>()
{
new CardAction() { Title = "1. All lights are green.", Type = ActionTypes.ImBack, Value = "All lights are green." },
new CardAction() { Title = "2. DSL light is OFF/Red/Blinking Green.", Type = ActionTypes.ImBack, Value = "DSL light is OFF/Red/Blinking Green." },
new CardAction() { Title = "3. Internet light is OFF/Red/Amber or blinking red and green.", Type = ActionTypes.ImBack, Value = "Internet light is OFF/Red/Amber or blinking red and green." },
new CardAction() { Title = "4. Power light is OFF/Red/Amber or blinking.", Type = ActionTypes.ImBack, Value = "Power light is OFF/Red/Amber or blinking." },
};
reply.Attachments = new List<Attachment>() { card.ToAttachment() };
reply.AttachmentLayout = AttachmentLayoutTypes.List;
var options = new PromptOptions()
{
Prompt = reply,
};
await stepContext.Context.SendActivityAsync(reply, cancellationToken);
Thanks!
You need to check if there are any attachments. I have some middleware that sets the speak on message and use the following code:
if (string.IsNullOrEmpty(message.Text))
{
if (message.Attachments[0].Content is HeroCard attachment)
{
message.Speak = TextToSpeechHelper.ConvertTextToSpeechText(attachment.Text);
}
}
else
{
message.Speak = TextToSpeechHelper.ConvertTextToSpeechText(message.Text);
}
You'd have to adjust it to set the text and translate.
Below is a full example of what my middleware is. Keep in mind this middleware sets the speak to the text and sets the input hint.
public class TextToSpeechMiddleware : IMiddleware
{
private readonly IEnumerable<string> ignoreList;
public TextToSpeechMiddleware(string speakIgnore)
{
ignoreList = GetSpeakIgnore(speakIgnore);
}
public Task OnTurnAsync(ITurnContext turnContext, NextDelegate next, CancellationToken cancellationToken = default(CancellationToken))
{
turnContext.OnSendActivities(OnSendActivities);
turnContext.OnUpdateActivity(OnUpdateActivity);
return next(cancellationToken);
}
private static IEnumerable<string> GetSpeakIgnore(string value)
{
string[] ignoreList = value.Split(';');
return ignoreList.Select(i => i.Trim())
.Where(i => !string.IsNullOrEmpty(i));
}
private Task<ResourceResponse> OnUpdateActivity(ITurnContext turnContext, Activity activity, Func<Task<ResourceResponse>> next)
{
ConvertTextToSpeech(activity);
return next();
}
private Task<ResourceResponse[]> OnSendActivities(ITurnContext turnContext, List<Activity> activities, Func<Task<ResourceResponse[]>> next)
{
foreach (Activity currentActivity in activities.Where(a => a.Type == ActivityTypes.Message))
{
ConvertTextToSpeech(currentActivity);
}
return next();
}
private void ConvertTextToSpeech(Activity message)
{
Activity initialMessage = message;
try
{
if (message.Type == ActivityTypes.Message)
{
bool ignoredSpeak = false;
if (string.IsNullOrEmpty(message.Speak))
{
if (string.IsNullOrEmpty(message.Text))
{
if (message.Attachments[0].Content is HeroCard attachment)
{
message.Speak = TextToSpeechHelper.ConvertTextToSpeechText(attachment.Text);
}
}
else
{
message.Speak = TextToSpeechHelper.ConvertTextToSpeechText(message.Text);
}
message.Speak = message.Speak.Trim();
if (ignoreList.Where(i => message.Speak.ToLower().StartsWith(i.ToLower())).Count() != 0)
{
message.Speak = null;
ignoredSpeak = true;
}
}
else if (string.IsNullOrWhiteSpace(message.Speak))
{
message.Speak = " ";
}
if ((!string.IsNullOrEmpty(message.Speak) && (message.Speak.EndsWith("?") || message.Speak.StartsWith("Is this correct?")))
|| (!string.IsNullOrEmpty(message.Text) && message.Text.EndsWith("?"))
|| ignoredSpeak)
{
message.InputHint = InputHints.ExpectingInput;
}
// IOs won't work with expecting input
if (message.Recipient.Name.EndsWith(":ios"))
{
message.InputHint = InputHints.AcceptingInput;
}
}
// Logic needed to increase speech speed.
// if (!string.IsNullOrEmpty(message.Speak))
// {
// message.Speak = #"<speak version='1.0' " + "xmlns='http://www.w3.org/2001/10/synthesis' xml:lang='en-GB'><prosody rate=\"1.5\">" + message.Speak + "</prosody></speak>";
// }
}
catch (Exception)

I'm working on an application based on .NET Framework 4.8. I'm using Microsoft Batching API. The below are code snippets

NCTB: I noticed that after opening the dialog to scan the QR CODE the ReceiveDetections method get called frequently and the scanned value comes in detections parameter .which is normal and it supposed to do so.But the problem is after a successful scan it should not call anymore.
I encountered a “date” issue with Bot in TEAMS, The date value cannot render at LeaveRequest() properly. However, the same bot works fine in Bot Emulator.
Following is my sample code. How to fix (or workaround) this issue?
Select a date from date picker and submit
System does not render the first field value.

};
card.Body.Add(fromDate);
AdaptiveTextInput toDate = new AdaptiveTextInput()
{

Placeholder = "To Date",
Value = DateTime.Today.ToUniversalTime().ToString("u")
};
card.Body.Add(toDate);
card.Actions.Add(new AdaptiveSubmitAction()

});

Thanks for reaching out!! This is a known issue. We have a bug on this and we are working on getting this fixed.
working on QnAMaker. The bot responses well with both Text and HeroCard responses on the Emulator and the WebChat. However, it is not sending the formatted HeroCard via my channel(Skype). I have rebuilt the application using build.cmd. Restarted the Azure services. Still no help.

i've translated the quickblox's sample app for Xamarin forms in Xamarin iOS and Android native.
Everything works "except" that the retrieving of the message fails.
I send the message from one client, and the event is catched from the other chat occupant:

}
long story short the sdk receive the message but apparently fail to parse the body message. fire the handler but if empty don't call the privateChatManager.MessageReceived.
could anyone help please?
Thank you
