如何取得浏览器的历史记录，读取为字符窜形式
就是读取到以后如何列出来（读取文件夹以后出现的是什么昨天、今天之类的），   如何列出所有浏览过的地址，就像IE   History   Manager（http://www.cleanersoft.com/iehistory/iehistory.htm）作的那样

.net 2.0中的autocomplete正是通过此方法实现的,2.0中实现的原型

private void SetAutoComplete(bool reset, bool recreate)
{
if (base.IsHandleCreated && (this.childEdit != null))
{
if (this.AutoCompleteMode != AutoCompleteMode.None)
{
if ((!this.fromHandleCreate && recreate) && base.IsHandleCreated)
{
