Are your threads worker threads and you want to update data in a dialog created by your main thread?

What is the value of lpParam, i.e. does it point to a properly created dialog? Also what is the exact detail of the assertion?

LpParam contain Recorded buffer Value and it will do processing in thread

Call UpdateData only from the same thread that created the dialog and its controls (the GUI thread), not from any worker threads. If you want to update your dialog regularly, either use a timer (SetTimer[^]/CWnd::SetTimer[^]) or send/post (SendMessage[^]/PostMessage[^]) messages towards your dialog from the worker thread. Also, if sending/posting messages, try using the handles of the windows you are trying to send/post messages to rather then handing the pointers to any CWnd-descendants (like CDialog) over to the thread and calling its methods.
