应用单片机的时候，经常会遇到需要短时间延时的情况。需要的延时时间很短，一般都是几十到几百微妙(uS)。有时候还需要很高的精度，比如用单片机驱动DS18B20的时候，误差容许的范围在十几uS以内，不然很容易出错。这种情况下，用计时器往往有点小题大做。而在极端的情况下，计时器甚至已经全部派上了别的用途。这时就需要我们另想别的办法了。

In c++ risks is a reference to a variable which exists i.e. one 2nd name for the same variable. This program is broken up into functions.露the function hand constitutes the entrance point of the program, firstly there is the function message which uS affiche hello , and the second function produced 露procedure affich_calcul, one declared the prototype and one it definite after one made the call has this function.

This control is another extension to the now standard and widely uSed ListView control. I have included some of the more common features: shaded columns, column sorting (with data type), but the real addition is the FILTERBAR features of the header. This implementation eliminates all of the work of dealing with the filter messages and item filtering by incorporating it into the control. This could have been implemented as delegates, but we create controls to do the work for uS, don t we? I would like to thank Carlos H. Perez since a lot of the implementation came from examples he set with his ListViewEx control.
