how to make outer while loop runs slower than the inner one

Question

hello... i need help with making my outer whileloop runs slower than the inner while loop...

to make them that both runs at the same moment, i have used continue method...

but when i compile, the inner loop runs with the same rate as outer one...i have used thread.sleep(1000) for outer loop and thread.sleep(1) for inner loop... when i compile, the innner loop goes each second instead of each milisecond.. my continue make the inner loop dependent on outer loop... appreciate any help...

the codes are:

while (t == true)
{
try {
cd.TimeTick();//tick time
lblTime.Text = cd.GetTime();//put time
Thread.Sleep(1000); //delay with one second
Application.DoEvents();
while (tLu == true)
{
try {
cdLu.TimeTick();//tick time
lblLunch.Text = cdLu.GetTime();//put time
Thread.Sleep(1); //delay with one milisecond
Application.DoEvents();
throw new Exception();
}
catch (Exception)
{
throw new Continue();
}
}
