  • Edited

I folks,

   I developed a desktop-based Application. When Application runs automatically login. whenever I get message 2nd message onwards. every time the application opened any other people sent me the message I can't get properly. this problem comes once I opened an application.

for ex: 

1. User1 -----> User2 -- message not comes

2. User1 -----> User2 -- message Received

3. User1 -----> User2 -- message Received

 I get the second message onwards. First Message did not get it. How to Fix this?

    Hi,

    I notice several pb in the code snippet provided ...

    1) You call twice InitializeComponent() (in App() method and in InitializeSDK())

    2) Create main SDK objects (Contacts, Conversations, InstantMessaing, etc ...) before to use login method

    3) Define events (ConnectionStateChanged, MessageReceived , etc ...) also before to use login method

    4) As described in the documentation here you need to received event InitializationPerformed from Application object before to use any feature of the SDK

    Once all thess problems has been corrected, do you still have the same trouble ?

    already done what you tell...

    1) InitializeComponent must be done in App() - not after.

    2) rainbowContacts objects (and others) is created twice and still after login

    3) events are still created after login

    4) InitializationPerformed  event is not managed ...

    So you did  very few updates ...

    Most of the code I am used from https://github.com/Rainbow-CPaaS/Rainbow-CSharp-SDK-Samples/blob/master/Windows_NetFwk/InstantMessaging/InstantMessaging.cs

    Hi,

    I have updated the InstantMessaging sample with an option to allow auto-logon when the application sample is started (previously you must have connected successfully with a valid account / password since we get info from the cache to get credentials)

    There is no problem to receive the first incoming message (and all others).

    Regards,
    Christophe

    Rainbow C# SDK is built as a .Net Standard library. So it's compatible with any superior layer of .Net including WPF.

    As example a full mobile application (for Android and IOS) is available in Xamarin Forms using this SDK without any trouble. I use this mobile Application every day on my own Android device for my work.

    I spent already a lot of time with your question ... It would have been better to clearly describe it from the start.

    And again, your latest code snippet shows a lot of your misunderstanding in coding in C #. I really think the problem is more here than in the SDK.
