I am trying to build a control that the user can use to send feedback to developer. I am using email as a delivery method and I leverage sendgrid email service for this. Now I want to know the users email address so I can respond back to the user's concern. I am not sure how to get the user's email in window 10. Any help or pointers please?
I would strongly recommend to use the sharing approach that has been introduced with Windows 8 - instead of writing and maintaining your own mail functionality and trying to access additional user data.
Have a look at the existing and built in e-mail functionalities. They make use of the user's connected mail accounts and the mail app. This way you don't need to worry about handling the message transmission or anything but rather hand the information over to the mail client. This way you also know how to reply back.
And as a bonus, the user can still access their message via the Sent Mails folder :)
There is a specific class for that, the EmailMessageClass (https://msdn.microsoft.com/en-us/library/windows/apps/windows.applicationmodel.email.emailmessage.aspx?cs-save-lang=1&cs-lang=csharp#code-snippet-1) as well as a dedicated guide with code example.

Essentially you can prepopulate the Mail fields with necessary app information where applicable. The user gets to choose which accounts he wants to send the mail from, but it will open in the mail client.
I want to try to send SMS to a cellphone in Austria. I have set up a free trial Twilio account to do so. however, my Twilio account seems not to be capable of doing so. but I think it should be possible to send SMS with the trial account?
This is a screenshot of my Twilio number where you can see that it's not capable of messaging:
this is the exception i get when running my python-code which tries to send the SMS:
twilio.rest.exceptions.TwilioRestException: HTTP 400 error: 21606: The From phone number +43720881723 is not a valid, SMS-capable inbound phone number or short code for your account.
any idea on how I can get this running? in other words: how can I activate SMS-capability for my free Twilio account? if this is possible, what are the limitations, i.e., how many free SMS messages can I send?
thanks!
To send SMS with trial twilio account TEST ACCOUNT SID and TEST AUTHTOKEN which is placed inside Phone Number > Tools > Test Credentials rather than ACCOUNT SID and AUTHTOKEN given by Console Dashboard > Account Summary.
Because ACCOUNT SID and AUTHTOKEN is bind after you buy the twilio number and TEST ACCOUNT SID and TEST AUTHTOKEN is bind with +15005550006.
If you received this error while trying to authenticate with your Test Credentials, you probably tried to send a message with a From number from your live account. The only number that can be used to send successful messages with your Test Credentials is +15005550006
If you use this number +15005550006 along with your 'demo' twilio sid and token, this will show you the success (no error) but it actually not sending you any sms/ text.
Go to this page https://www.twilio.com/console/sms/getting-started/build and set a phone number like "+133438*****". Twilio will auto provide you a number like (334) 384-**** and by clicking the buttons you need to generate the phone number as like "+133438*****". Once you successful, try to use your 'live' sid and token number within the API. But before integrating the same, you can fire a SMS in your own phone number from this page https://www.twilio.com/console/sms/getting-started/build.
Otherwise, the API error message will show you that - [HTTP 400] *Unable to create record: The 'From' number +1*********** is not a valid phone number, shortcode, or alphanumeric sender ID.
Your number is not capable (configure) for SMS sending. Go to your account and enable SMS capability. After that you will see a green check mark with text
"https://demo.twilio.com/welcome/sms/reply/" instead of Messaging". Similar to below screenshot
I got this error when I was using test Account SID and test Auth Token along with a regular number. Then I changed the Account SID and Auth Token to the regular ones and it worked as expected, i.e. allowed me to send SMS to a verified phone number.
If your number is sms capable and still you are getting the 21606 error, then check 'Active Numbers' tab under 'Manage Numbers'. It should show your number '+43720881723' as an active number.
I had found two errors in this regard, the problem is in the evaluation account and its limitations, but I found a way around it, within the rules of twilio.
Access this page and follow the instructions: https://www.twilio.com/console/sms/get-setup
Write down the number he gives you, this will be your new number, paste it in your application, it will solve your problem, but you still need to do one last thing, you need to check the number you want to send the message to, access this page:
https://www.twilio.com/console/phone-numbers/verified
After you do this, you can try to send the message again, if it fails, the problem must be elsewhere, as it worked for me.
To send SMS with trial Twilio account, test ACCOUNT SID and test AUTHTOKEN which can be found at
Phone Number > Tools > Test Credentials rather than ACCOUNT SID and AUTHTOKEN given by Console Dashboard > Account Summary.
In my case, upgraded my Twilio account and copied the US Florida phone number as it is (9549386330) and got
"is not a valid, SMS-capable inbound phone number or short code for your account"
I only needed to put "1" in front of 19549386330 and it worked.
so check the country code of your phone number as well.
I need my application to send an e-mail to me directly without using the EmailComposeTask.
I also don't want to use a webservice for that.
Is there any open-source framework I could use?
There is currently not a way to send email w/o user input unless you want to send some information to a service and have the service send the email
I want to have a mobile number validate for my site not just string validations ..what i need is to actually validate the mobile number with the same user exists..
one option i know is to send a pin to that mobile number & ask user to put that pin on form submit to validate ...so are there any ready to use services for this to use it on my website or what i have to do for this ...
Also tell if you know any other options available
You could use http://www.twilio.com/ to call the number and have the person respond (press 1 for ok, 0 for not ok) to your call.
But note that calling the number would work if the number was either a land-line or mobile. If you want to make sure that the number is mobile, then SMS is a good idea.
Twilio has an SMS api too.
you can use this service that give you web service that you can use to validate mobile number in any country http://www.data-8.co.uk/integr8/services/mobile_validation.aspx#Demo
Some push agregattors have APIs for HLR-look up, then you could know if number is right and it is active or off, etc.
If it's not super important that someone can fake their confirmation, then you could look at some of the headers received from the network operator containing the user's number: Can a mobile web application access the devices phone number?
help out a noob with a simple web development question??
I want to create a Contact-Me form on my website, but I'd like it to not go through the email client that's installed on the user's machine, in case they're at a public terminal. I don't mind if the email comes from "me" to "me", as long as nobody can use it to spam me! Is there a way to get it to safely use the SMTP server it uses when I myself send an email? (This is a Yahoo-hosted website, and I have a Yahoo email account associated with it.)
Sure. You want a simple contact form that posts to some .php/.asp/.whatever script. That script should be able to use the SMTP server from your host (Yahoo!). You may end up sending from a different email than your personal #yahoo.com one, but just look up the info for your host.
I Googled "yahoo hosting send email" and the first result looks very relevant: http://help.yahoo.com/l/us/yahoo/smallbusiness/webhosting/php/php-17.html
As for wanting to stop spam from coming in through the form, just implement a captcha. I'd recommend using reCAPTCHA - it's free and has sample code that you can basically just plug in.
