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)

SafeNativeMethods.SHAutoComplete(new HandleRef(this, this.childEdit.Handle), flags);
}
else if (this.stringSource != null)
{
this.stringSource.RefreshList(this.GetStringsForAutoComplete(this.AutoCompleteCustomSource));
}
else
{
this.stringSource = new StringSource(this.GetStringsForAutoComplete(this.AutoCompleteCustomSource));
if (!this.stringSource.Bind(new HandleRef(this, this.childEdit.Handle), (int) this.AutoCompleteMode))
{
throw new ArgumentException(SR.GetString( "AutoCompleteFailure "));
}
}
}
}
