发帖数: 2744 | 5 There are two dateTimePickers on a winform, which requires dt2 > dt1;
if dt1 is picked greater than dt2, reset dt1 to dt2-1; but the messagebox
pops
out twice. How to disable the second one? ..EnableEvents seems not working
//The code is as follows.
private void dateTimePicker2_ValueChanged(object sender, EventArgs e)
{
if (this.dateTimePicker1.Value > this.dateTimePicker2.Value)
{
MessageBox.Show("This date should NOT be earlier then " +
this.dateTimeP |

发帖数: 3965 | 6 我有两组数据，包括id 和 日期。他们都是一个id对应多个日期。我想把数据A当base,
left join 数据B，但是条件是，B的日期是在A的日期的前一年内。比如A日期是4/4/
2000，那如果B的日期在4/5/1999 - 4/4/2000,就保留。
A
id dt1

我希望得到C像这样。

发帖数: 16779 | 8 在中国颇有一些cat低的店。 欧美几乎所有店cat都很高。
hilton点基本只适合中国用。
北京dt1万点，用钱要100-150美元。
北京一万点可以换一万吗？用钱买是多少钱一万的酒店啊？我怎么随便搜的一个小镇的
hilton inn都要40000点一晚啊（$109） |

香港入境，航空，陆路，水路盖章颜色不同，如果DT3次就入黑名单！
我有一次虽然有签证，但不想用，陆进水出，被DT1次，后来每次出入都问。 |

发帖数: 4 | 10 Suppose T1,T2...Tn are i.i.d. nonnegative random variable with pdf f(t).
For two fixed positive value a and b, I have to compute the following
probability, could you plz give some suggestins? Thanks.
Pr(T1+T2+...Tn < a, T1
My solution:
Pr(T1+T2+...Tn < a, T1
\int_0^{b} f(t1) \int_0^{b} f(t2) ... \int_0^{a-t1-t2-...-t_{n-1}} f(tn) dtn
dt_{n-1} ...dt1
But it seems impossible to compute the integral. |
