You SHOULD NOT do SetWindowText for a window that belong to other thread. It
may cause a deadlock. in general, other than PostMessage, you should not
mess with other thread's windows.

//the Best solution is 2 use static thread 2 access Dialog Member
Function

// Add These 2 globals in threadmemberfnDlg.h

CWinThread *MemberfnThread;
CThreadmemberfnDlg *Dlgobj = NULL;

//Add Static Member Fn to threadmemberfnDlg.h

pubic:
static UINT DlgMemFnThread( LPVOID nParam );

void CThreadmemberfnDlg::OnStartthread()
{
// Begin Thread
MemberfnThread= AfxBeginThread(DlgMemFnThread, this,
THREAD_PRIORITY_NORMAL, 0, 0, NULL);

}

// Thread Function here
UINT CThreadmemberfnDlg::DlgMemFnThread(LPVOID nParam)
{
Dlgobj = (CThreadmemberfnDlg*) nParam;
Dlgobj ->SetWindowText("Static Thread Works Fine 2 Access Dialog
Member Fn");
//Dlgobj->OnOK()

// using Dlgobj now u can access any Member Fn of Dlg class
return 0;
