{ Important: Methods and properties of objects in VCL can only be used in a
method called using Synchronize, for example,
Synchronize(UpdateCaption);
and UpdateCaption could look like,
procedure TiaRotateTimer.UpdateCaption;
begin
Form1.Caption := 'Updated in a thread';
end; }
{ TiaRotateTimer }
procedure TiaRotateTimer.Execute;
begin
repeat
sleep(Dtime);
sendmessage(Handle1,CM_ROTATEDON,0,0);
until terminated;
{ Place thread code here }
