ASP.NET MVC SiteMap provider — How to 'hide' single items in the actual menu

由 一笑奈何 提交于 2019-12-10 03:29:06
问题 I am using the ASP.NET MVC SiteMap provider in a project, and it is working great. I am having a tough time trying to figure out how to hide a menu item however. The menu item I want to hide from displaying in the global navigation is my "Site Map" page. Now I know that there is something called a VisibilityProvider available to me on the mvcSiteMapNode - but I can't seem to figure out how to make it work. 回答1: First, I suggest you read this wiki page: Creating a Custom

问题 I'm playing with the following Javascript + SVG + D3 code. http://bl.ocks.org/1095795 The code is here: https://gist.github.com/1095727 In short, I need unique images for each node (instead of the duplicated smiley face image as it's pulling now), but I'm not savvy enough to make it happen.

Networkx neighbor set not printing

由 夙愿已清 提交于 2019-12-09 18:23:59
问题 I have a little problem with my networkx code. I am trying to find all the neighbors from a node in a graph, but.... neighbor = Graph.neighbors(element) print(neighbor) outputs: <dict_keyiterator object at 0x00764BA0> Instead of all the neighbors I am supposed to get... A friend of mine, who is using an older version of networkx does not get this error, his code is exactly the same and works perfectly. Can anyone help me? Downgrading my networkx is not an option. Edit: This is my complete

How can I make rectangle selection on multiple nodes with graph dracula?

由 生来就可爱ヽ(ⅴ＜●) 提交于 2019-12-09 18:00:54
问题 I am working on some graph visualizations, and I am using the JavaScript library graph Dracula. Now, with this library, when I want to move a node I have to click the node I want to move and move it on the desired place (with drag and drop). But, what I want to do is to select more nodes and move all of them. I can't figure out how to do this, since I am not so experienced in JavaScript programming. So, my question is: How can I select multiple nodes with rectangle selection and move them?

Run multiple elasticsearch nodes as a service on one Ubuntu-Server

由 僤鯓⒐⒋嵵緔 提交于 2019-12-09 13:05:35
问题 I have a server running Ubuntu 14.04 with 220 GB of ram on which I'd like to run elasticsearch. According to the documentation, one node should not have more than 32 GB of RAM, so I guess I have to run several nodes on this one machine in order to make use of all that RAM. I'm considering running 4 nodes with 28 GB of memory for each. How do I set this up as an ubuntu service, so that all of the nodes automatically come back up after a system reboot for example? I guess I have to edit /etc

问题 In npm, how can I run two or more parallel tasks, but waiting for the resource that the first task will create to be available to the second task to use it, and so forth? example (conceptual): npm run task1 & waitfor task1 then task2 & waitFor task3 then task4 ... any ideas? EDIT As an example: Lets say that my first task is starting a webserver, and my second task is consuming data from that web-server every time an event happens. Another example: My first task could be starting webdriver
