Assign a variable in your worker thread (when it is created) something like:

// Created thread;

// I do it this way so I can use any window I want for messages.
// Assume this sets a variable in the thread object called m_pUIWnd of type
CWnd *
pThreadObject ->SetUIWnd(this);

From worker thread:

m_pUIWnd->SendMessage(MYMESSAGE,pMyWordData,pMyLongPointer;
// The pMyLongPointer could point to the data you want to have added in the
control

I apologize, can you give me an example?

This is how I've created a thread..

void CvcatTransmit::OnTransmitStart()
{
        thread = (CThread *)AfxBeginThread(RUNTIME_CLASS(CThread),
                                        THREAD_PRIORITY_NORMAL,
                                        0, //stacksize
                                        CREATE_SUSPENDED);
        thread->SetMe = true;
        thread->ResumeThread();
}

CThread is a class that inherits CWinThread.
Now, in my thread I need to be able to update my edit boxes which
reside in the CvcatTransmit class.

this is what I've tried:

inside of Thread.h

CEdit * MyBox;

then inside OnTransmitStart()

thread->MyBox = &vcatBox;

and it fails to work.. any other ideas?
