On the other hand, you can, however, make a pseudo-relative element, by creating a zero-width, zero-height, relatively positioned element, essentially solely for the purpose of creating a reference point for position, and an absolutely positioned element within that: Hi there, I'm 100px offset from where I ought to be, from the top and left. 回答2: Add a margin equal to the pixels that

The control flow looks much more like "traditional" programming instead of "web" programming. Is that a correct impression? I know it's about Web programming but it's does not looks like it from the programmers side. It looks much more than driving "desktop" applications. Does this clarify the question a bit? 回答1: Your impression is correct. Seaside is designed for what I call a tree-like control flow, as desktop GUI apps have. Comparing

I need to check a flag for each of the tasks and run the task if it is set, if not skip and go to the next one. Each of the these task executes a stored proc. So i can check in the proc and "Return" if not set. I was looking for a "SSIS" solution if any. TIA PS 回答1: Between your control flow tasks, click on the arrow and choose Edit. When you do this, you get a dialog that allows you to check the "constraint" (success, completion or failure) of

The message payload after the HTTP Connector is a org.glassfish.grizzly.utils.BufferInputStream. What is the best way to transform this to a type where I can use a component such as a 'Splitter' or 'Expression' (using XPath) to split/route it? The 'Object to XML' doesn't seem to work and the splitter doesn't work when the payload is a String (i.e. using Object to String after HTTP). I would rather not write a custom Java transformer if there are

题目 题意： 每一个机器有一个物品最大工作数量，还有一个对什么物品进行加工，加工后的物品是什么样。给你无限多个初始都是000....的机器，你需要找出来经过这些机器操作后最多有多少成功的机器(111.....) 题解： st是网络流起始点，en是终止点 首先肯定是要拆点的，因为题目上给出的是每一个机器的最大加工数量。这是对于机器本身，所以拆点之后i->start和i->last这条边的容量就是机器的最大加工数量 这个题的话建图很清晰，只要它要加工的原始物品是000...类型的，它就可以和st建一条边，容量无限大。如果加工后的物品是111...这种类型的，那么就可以让这个i->last和en建一条边，容量都是无限大 之后的话如果某个机器加工后的产品可以作为某个机器的原料，那就让他们之间连一条容量无限大的边。这里要注意，当某个机器接受的原料某个部件为2，那这个位置有没有部件都可以连边 例：1机器原料为1 2 1，那么1 0 1和1 1 1的产品他都可以接收 因为题目要求最后要输出那两个机器之间有流量，所以只要跑完最大流之后一个一个点的去检查。发现这个点和其他点之间有流量，那就出输出它(具体看代码) 代码： 1 #include <cstdio> 2 #include <algorithm> 3 #include <iostream> 4 #include <cstring> 5
