Performance of application

hi all,
i have an application that will loop a long amount/complicated code (to avoid lock up, i am currently using "Doevents"). With the large amount code, it make the computer usage to 100%. Now i am planing to using timer to run it to decrease the usage of pc.Could anybody tell me any technique / method can apply to reduce the usage of pc/increase the performance? Windows services or other technique?

any tips are welcome

regards

There are no other techniques than better code and to use DoEvents wisely. There have been many discussions on this but I shall provide you with something better... PROOF!!! Look at the project CPU Usage Release
