**Description**  
Hi  
I am using latest ZOOM sdk version of v5.0.24433.0616 in Visual studio 2017 C++. I want to change user name after In meeting status. I am currently using ChangeUserName function of IMeetingParticipantsController. But it is returning SDKERR\_INTELNAL\_ERROR.  
What am i doing wrong? Can you please help me?

**Which version?**  
v5.0.24433.0616

**Code which i am using for it**  
ZOOMSDK::IMeetingService\* pMeetingService = SDKInterfaceWrap::GetInst().GetMeetingService();  
ZOOMSDK::IMeetingParticipantsController\* pController = pMeetingService-\>GetMeetingParticipantsController();  
if (pController)  
{  
ZOOM\_SDK\_NAMESPACE::IUserInfo\* puserInfo = getCurrentUserInfo();  
if (puserInfo)  
{  
ZOOMSDK::SDKError error = pController-\>ChangeUserName(puserInfo-\>GetUserID(), displayTitle.c\_str(), false);  
if (error == ZOOM\_SDK\_NAMESPACE::SDKERR\_SUCCESS)  
sendMeetingInfoCommand();  
}  
}

getCurrentUserInfo function is returning my userinfo.

Hi @vaghaninirav10,

Thanks for the post and pardon the late response. Based on the log provided, the request to change the user name was failed but it did not show the root cause. Based on the code snippet, we are able to use the code snippet provided and successfully change user name with our demo app(So we are not able to reproduce this issue with our demo app). Is this happening every time you run this code?

Thanks!

Hi @vaghaninirav10,

Thanks for confirming. Based on the log, it looks like the interface changeUserName function is not called in the main thread. The SDK interfaces need to be called in the main thread. Please have a try.

Thanks!
