Hi,

I need to retrieve conversation messages from a particular contact, I have used GetMessagesFromConversation and GetMessagesFromContactId, both are not return any messages ie, count=0 in their message list.

This is the code which I used to retrieve messages:

Rainbow.Contacts contacts = myApp.GetContacts();
String contactID = "xxxxxxxxx"; // Your contact id
contacts.GetContactFromContactIdFromServer(contactID, callback1 =>
{
if (callback1.Result.Success)
{
Contact contact = callback1.Data; // Contact found
Rainbow.Conversations conversations = myApp.GetConversations();
conversations.GetConversationFromContactId(contactID, callback2 =>
{
if (callback2.Result.Success)
{
Conversation convObj = callback2.Data; // List of conversations
Rainbow.InstantMessaging imMsglist = myApp.GetInstantMessaging();
imMsglist.GetMessagesFromConversation(convObj, 3, callback3 =>
{
if (callback2.Result.Success)
{
}
else
{

}
});
}
else
{
// Exception occurs
Exception e = callback2.Result.ExceptionError;

}
});
}
else
{
// Exception occurs
Exception e = callback1.Result.ExceptionError;

}
});

  Hi,

  In the code snippet provided, there is a mistake after this:

  imMsglist.GetMessagesFromConversation(convObj, 3, callback3 =>

  {

  if (callback3.Result.Success) {  // Here you use callbakc2 instead
  

  ...

  }

  }

  );

  Hope this helps,
  Regards.
  Christophe

  Have you tried this example:

  https://github.com/Rainbow-CPaaS/Rainbow-CSharp-SDK-Samples/tree/master/InstantMessaging

  Using this sample with your accounts do you have still the pb ?

  Hi Sathya,

  Do you have still your problem ?
  Do you reproduce it with the sample coming from the SDK ?

  Thanks,
  Regards.

  Hi Christophe,

  Yes, I have this problem. When I debug this code, the debugger never came inside GetMessagesFromConversation code even in else portion as well.

  imMsglist.GetMessagesFromConversation(convObj, 3, callback3 =>{

  if (callback2.Result.Success)
  {
  }
  else
  {

  }

  }

  Hi,

  Again in your code snippet there is an error ... (callback2 used instead of callback3 ...)

  Do you check the pb with the sample provide in the SDK ?

  Could you share your code ? So I could try to reproduce the pb.

  Thx

  Hi Cristophe,

    I copied that lines from previous post.

    Here below I put my sample code,

  ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
  Rainbow.Application myApp = new Rainbow.Application();
  myApp.SetApplicationInfo(ConfigurationManager.AppSettings["AppId"].ToString(), ConfigurationManager.AppSettings["AppSecretKey"].ToString());
  myApp.SetHostInfo(ConfigurationManager.AppSettings["Hostname"].ToString());
  
  myApp.Login("username", "password", callback =>
  {
  if (callback.Result.Success)
  {
  Rainbow.Contacts contacts = myApp.GetContacts();
  String contactID = "xxxxxx"; // Your contact id
  contacts.GetContactFromContactIdFromServer(contactID, callback1 =>
  {
  if (callback1.Result.Success)
  {
  Contact contact = callback1.Data; // Contact found
  Rainbow.Conversations conversations = myApp.GetConversations();
  conversations.GetConversationFromContactId(contactID, callback2 =>
  {
  if (callback2.Result.Success)
  {
  Conversation convObj = callback2.Data; // List of conversations
  Rainbow.InstantMessaging imMsglist = myApp.GetInstantMessaging();
  imMsglist.GetMessagesFromContactId(contactID, 3, callback3 =>
  {
  if (callback3.Result.Success)
  {
  }
  else
  {

  }
  });
  }
  else
  {
  if (callback2.Result.Type == SdkError.SdkErrorType.IncorrectUse)
  {
  // Bad parameters used
  string errMsg = callback2.Result.IncorrectUseError.ErrorMsg;
  }
  else
  {
  // Exception occurs
  Exception e = callback2.Result.ExceptionError;
  }
  }
  });
  }
  else
  {
  if (callback1.Result.Type == SdkError.SdkErrorType.IncorrectUse)
  {
  // Bad parameters used
  string errMsg = callback1.Result.IncorrectUseError.ErrorMsg;
  }
  else
  {
  // Exception occurs
  Exception e = callback1.Result.ExceptionError;
  }
  }
  });
  }
  else
  {
  // A pb occurs
  if (callback.Result.Type == SdkError.SdkErrorType.IncorrectUse)
  {
  // Bad parameter(s) used
  string errMsg = callback.Result.IncorrectUseError.ErrorMsg;
  }
  else
  {
  // Exception occurs
  Exception e = callback.Result.ExceptionError;
  }
  }
  });

  Hi Sathya,

  1) When you login you need to wait the event "ConnectionStateChanged" with a value equal to ConnectionState.Connected before to continue any action

  Cf. https://hub.openrainbow.com/#/documentation/doc/sdk/csharp/api/Rainbow#Rainbow.Application.ConnectionStateChanged

  2) You can get messages only wih a contact in your roster. So after

  Rainbow.Contacts contacts = myApp.GetContacts();

  // One you connection state is Connected
  contacts.GetAllContacts(...)
  String contactID = "xxxxxx"; // Your contact id
  contacts.GetContactFromContactId(contactID) => Must return a non null Contact object

  
  3) As suggested could you first use the SDK Sample with your accountID to check if you retrieve well your messages.

  Regards,
  Christophe
