I am making an alerting application in Windows 10 using XAML and C#. I am using WNS to do my push notification. I have written a function that is triggered when I receive a notification within the app. Here is my code:
private async void Channel_PushNotificationReceived(PushNotificationChannel sender, PushNotificationReceivedEventArgs e)
{
e.Cancel = true;
string jsonPayload = "{\"user_id\":\"" + CommonVariables.AuthenticateUserResponseDetails.user.id + "\"}";
HttpClient client = new HttpClient();
string postUrl = CommonVariables.SERVER + CommonVariables.Get_Alert;
HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Post, postUrl);
//encrypt tase
EDecrypt encrypt = new EDecrypt();
jsonPayload = encrypt.AES_Encrypt(jsonPayload, CommonVariables.EncryptionKey);
request.Content = new StreamContent(new MemoryStream(System.Text.Encoding.UTF8.GetBytes(jsonPayload)));
var result = await client.SendAsync(request);
string response = string.Empty;
response = await result.Content.ReadAsStringAsync();
EDecrypt edecrypt = new EDecrypt();
response = edecrypt.AES_Decrypt(response, CommonVariables.EncryptionKey);
response = response.Replace("\"", "");
await Dispatcher.RunAsync(CoreDispatcherPriority.High, () =>
{
messageBox(CommonVariables.AuthenticateUserResponseDetails.user.name + " Please attend " + response + " Theatre");
});
ConfirmSeen();
}
When I receive a notification however the message box appears twice. I have tried putting the message box code outside the Dispatcher but the app errors. What have I done wrong?
