if its to much. Im using a control which Ive added labels. Basically I
want update the data every second. Ive rad up on threadind and now
know that I need to use a delegate with my control because it uses a
sepperate thread. I cant work out how to do it though. Heres the code
for my control.

backAmountAvailable3, layPrice1, layAmountAvailable1, layPrice2,
layAmountAvailable2, layPrice3, layAmountAvailable3);
}
}
}
the ... row.DisplayPrices(currency,
backPrice1, backAmountAvailable1, backPrice2, backAmountAvailable2,
backPrice3, backAmountAvailable3, layPrice1, layAmountAvailable1,
layPrice2, layAmountAvailable2, layPrice3, layAmountAvailable3);
is the information thats Iwant to add each second to the control. I
cant work out how to set the delagate up. So far Im thinking in my
control I need to add something like ' public delegate my delegate
void onDisplayPrices(....same signature as diplay prices).
Id really like some help on this. Sorry for so much code.
Regards Robert
