(VB.NET UWP/WinRT) Twitter Tweet with an Image

Example to post a status update with an associated image/photo (or video).

Chilkat Universal Windows Platform (UWP) / WinRT Downloads

Chilkat for the Universal Windows Platform (UWP)

'  This example requires the Chilkat API to have been previously unlocked.
'  See Global Unlock Sample for sample code.

'  ----------------------------------------------------------------------
'  This initial setup, which involves setting the OAuth1 properties and connecting
'  to api.twitter.com, is only required once at the beginning.  Once connected, the same
'  object instance may be re-used, and if necessary, it will automatically reconnect
'  as needed.

'  Assume we've previously obtained an access token and saved it to a JSON file..
Dim json As New Chilkat.JsonObject
Dim success As Boolean = json.LoadFile("qa_data/tokens/twitter.json")

'  This ends the initial setup...
'  ----------------------------------------------------------------------

Dim tweetContent As String = "This is a test tweet with an image."

'  Send a tweet...
rest.ClearAllQueryParams()
rest.AddQueryParam("status",tweetContent)

'  Add list of media_ids to associate with the Tweet.
'  You may include up to 4 photos or 1 animated GIF or 1 video in a Tweet.
'  The image needs to have been previously uploaded.  The upload response gave us
'  the media ID we'll use to associate this tweet with the image (or video)
'  See Twitter Upload Media for sample code.
'  This example will add just a single image/photo.
rest.AddQueryParam("media_ids","793137045996646400")

Dim response As String = Await rest.FullRequestFormUrlEncodedAsync("POST","/1.1/statuses/update.json")

'  A successful JSON response looks like this:
