GetActiveWindow()isthread-specific.Youhavenoactivewindowsinyourworkerthread.

WhynotaddaCHhhhView*membertoyourMyClassclass(passitinintheconstructor):

classMyClass
{
CHhhhView*pView;
public:
MyClass(CHhhhView*view){pView=view;}
};

voidCHhhhView::OnButton1()
{
//TODO:Addyourcontrolnotificationhandlercodehere
MyClass*objMyClass=newMyClass(this);
AfxBeginThread(MyThreadProc,objMyClass);
}

NowyoucanusepViewinMyClassinsteadof((CMDIFrameWnd*)AfxGetMainWnd()->GetActiveWindow()).
