• databind a DropDownList control with a list of all sub directories that exist in a particular direct

  - by sushant

  I am wanting to databind a DropDownList control with a list of all sub directories that exist in a particular directory on the server. The directory I want to search is in the root of the application. I am fairly new to programming and I'm not sure where to even start. I found this code on a website: Dim root As String = "C;\" Dim folders() As String = Directory.GetDirectories(root) Dim sb As New StringBuilder(2048) Dim f As String For Each f In folders Dim foldername As String = Path.GetFileName(f) sb.Append("<option>") sb.Append(foldername) sb.Append("</option>") Next Label3.Text = "<select runat=""sever"" id=""folderlist""" & sb.ToString() & "</select>" I guess this is vb. but my tool is in asp, so is their something similar in vbscript so that I can use it.

• A depth (z-index) nightmare.

  - by JCOC611

  The best way to illustrate this question is with...a Fiddle! Before you visit the fiddle, notice there is text behind the grayest element, which is on top of a light gray element that has a border. There is a main wrapping div (root), and two wrapping divs inside (wrap1 and wrap2). The problem here is that I need the content of wrap2 (highlight) to be behind the content of wrap1 (text), but in front of the background of the root. This, however, must not change: The HTML, the elements and wraps should be left untouched. Excluding the order of wrap1 and wrap2 inside root. The highlight div must keep the absolute positioning. Styling highlight with background-color is not an option, the existence of highlight is a must. PS: the italics reference the id's of <div>s in the fiddle example, for whomever was too lazy to visit it.

• python - returns incorrect positive #

  - by tekknolagi

  what i'm trying to do is write a quadratic equation solver but when the solution should be -1, as in quadratic(2, 4, 2) it returns 1 what am i doing wrong? #!/usr/bin/python import math def quadratic(a, b, c): #a = raw_input("What\'s your `a` value?\t") #b = raw_input("What\'s your `b` value?\t") #c = raw_input("What\'s your `c` value?\t") a, b, c = float(a), float(b), float(c) disc = (b*b)-(4*a*c) print "Discriminant is:\n" + str(disc) if disc = 0: root = math.sqrt(disc) top1 = b + root top2 = b - root sol1 = top1/(2*a) sol2 = top2/(2*a) if sol1 != sol2: print "Solution 1:\n" + str(sol1) + "\nSolution 2:\n" + str(sol2) if sol1 == sol2: print "One solution:\n" + str(sol1) else: print "No solution!" EDIT: it returns the following... import mathmodules mathmodules.quadratic(2, 4, 2) Discriminant is: 0.0 One solution: 1.0

• ASP.NET/IIS: Tell IIS do not check for file existence

  - by AgileMeansDoAsLittleAsPossible

  In my Global.asax.cs, I have: routes.MapRoute("AssetCss", "css/{*path}", new { controller = "Asset", action = "Index" }); I also have this in a view: <link href="/css/Root/index.css" rel="stylesheet" type="text/css" /> The problem is that the AssetController does not invoke Index when /css/Root/index.css is requested. This is because a file actually exists at the path /css/Root/index.css. If I recall correctly, there's a checkbox setting in IIS that basically says "Do not check that a file actually exists at the request path [instead, let the RouteTable handle it]." (At least there is in IIS 6.) Is there something I can put in my Web.config that sets this IIS setting to true? How do I tell IIS to let my MVC routes handle the path even if a file exists at the path?

• Should every class have its own namespace?

  - by thehouse

  Something that has been troubling me for a while: The current wisdom is that types should be kept in a namespace that only contains functions which are part of the type's non-member interface (see C++ Coding Standards Sutter and Alexandrescu or here) to prevent ADL pulling in unrelated definitions. Does this imply that all classes must have a namespace of their own? If we assume that a class may be augmented in the future by the addition of non-member functions, then it can never be safe to put two types in the same namespace as either one of them may introduce non-member functions that could interfere with the other. The reason I ask is that namespaces are becoming cumbersome for me. I'm writing a header-only library and I find myself using classes names such as project::component::class_name::class_name. Their implementations call helper functions but as these can't be in the same namespace they also have to be fully qualified!

• Which entities should be Aggregate Roots?

  - by MylesRip

  If Book aggregates Chapter which in turn aggregates Page, then what should be the aggregate root? One possibility might be: Book is an aggregate root with Chapter as a leaf and Chapter is an aggregate with Page as a leaf. In this scenario, Chapter is a leaf in one aggregate and a root in another. Is this okay? Would it make sense in this scenario to have two repositories, one for Book and another for Chapter? If so, then couldn't the Chapter repository be used to circumvent the fact that access to Chapter should only happen via Book? What would be the best way to handle a situation like this?

• How to know if a std::list has been modified

  - by Nick

  I have this class: class C { public: C* parent; std::list<C> children; }; I can use this class in this way for example: C root; C child; root.children.push_back(child); // or other method of std::list (es: push_front, insert, ...) // Here child.parent is root // How can I set the parent of child? I want to do this work internally to my class without losing the functionality of std::list, is it possible?

• How to detect if breaking an edge will make a graph disjoint?

  - by the_graph_guy

  I have a graph that starts off with a single, root node. Nodes are added one by one to the graph. At node creation time, they have to be linked either to the root node, or to another node, by a single edge. Edges can also be created and deleted (one by one, between any two nodes). Nodes can be deleted one at a time. Node and edge creation, deletion operations can happen in any arbitrary order. OK, so here's my question: When an edge is deleted, is it possible do determine, in constant time (i.e. with an O(1) algorithm), if doing this will divide the graph into two disjoint subgraphs? If it will, then which side of the edge will the root node belong? I'm willing to maintain, within reasonable limits, any additional data structure that can facilitate the derivation of this information. Maybe it is not possible to do it in O(1), if so any pointers to literature will be appreciated.

• web-development: how do you usually handle the "under costruction" page"?

  - by Patrick

  hi, I was wondering what's the best way to switch a website to a temporary "under costruction" page and switch it back to the new version. For example, in a website, my customer decided to switch from Joomla to Drupal and I had to create a subfolder for the new CMS, and then move all the content to the root folder. 1) Moving all the content back to the root folder always create some problems with file permissions, links, etc... 2) Creating a rewrite rule in .htaccess or forward with php is not a solution because another url is shown including the top folder. 3) Many host services do not allow to change the root directory, so this is not an option since I don't have access to apache config file. Thanks

• GNU General Public License (v2): can a company use the licensed software for free?

  - by EOL

  When a library is released under the GPL v2, can a company use it internally for free? If they develop software based on it, do they have to release it under the GPL, even if they don't distribute it? Can they make money by using (not distributing) internally developed software that links to the GPL'ed library, without any compensation for the author? I am looking for a software license that only allows non-commercial uses (copy, modify, link to); the resulting derived programs must also be free for non-commercial uses. Is there any software license that does this for non-commercial uses, and prevents any commercial use (including using the software in order to make money)? It looks like the Creative Commons licenses are flexible enough to do something close to that, but I've read against using them for software. What do you think?

• Why would SQL be very slow when doing updates?

  - by ooo

  Suddenly doing updates into a few tables have gotten 10 times slower than they used to be. What are some good recommendations to determine root cause and optimization? Could it be that indexing certain columns are causing updates to be slow? Any other recommendations? I guess more important than guesses would be help on the process of identifying the root cause or metrics around performance. Is there anything in Fluent NHibernate that you can use to help identify the root cause of performance issues?

• Contents of a node in Nokogiri

  - by Styggentorsken

  Is there a way to select all the contents of a node in Nokogiri? <root> <element>this is <hi>the content</hi> of my æøå element</element> </root> The result of getting the content of /root/element should be this is <hi>the content</hi> of my æøå element Edit: It seems like the solution is simply to use myElement.inner_html(). The problem I had was in fact that I was relying on an old version of libxml2, which escaped all the special characters.

• building treeview

  - by DJPlayer

  I'm dynamically building a treeview given numerous stored procedures. the structure goes like this: OwnerRPColl.Search2() For Each root As OWNER_RP In OwnerRPColl Dim nd_Root As New TreeNode nd_Root = TreeView1.Nodes.Add(root.OWNER_RP_BUSNS_NAME) bldg.ID = root.ID bldgColl.Search(bldg.ID) For Each firstChild As BLDG In bldgColl Dim nd_lvl_One As New TreeNode With nd_lvl_One .Text = firstChild.BLDG_NAME_1 .Tag = firstChild.ID End With problem being is that I need to have labels for these.. meaning the first level of the treeview needs to say "users" when expanded displays users. Each of these users can have a building. The world building needs to be the example option, which then displays the building.. essentially I need a slick way to add the word in for the expanding level (instead of the value in the collection).

• selecting all text within a div on a single left click with javascript

  - by tstyle

  I have a simple non-clickable link within a div that looks like this: It's meant to be a sharable link that the user can copy paste into other things. For usability purposes, I want a single left click anywhere within the div to select the entire link: I don't know much about, javascript/web programming, so I've tried the following: <div id="share_link" onClick="select_all('share_link')"><%= request.url %></div> and this javascript <script type="text/javascript"> function select_all(id) { document.getElementById(id).focus(); } </script> This doesn't work. I'd like to know what's the simplest thing I should do to achieve what I want. I thought about changing the div to a text input or the text within to be a link, but ideally the content within should be read-only, non-editable, and non-clickable

• algorithm to find the three majority elements in an array

  - by Qiang Li

  Let's say there are three elements in a non-sorted array all of which appear more than one-fourth times of the total number of elements. What is the most efficient way to find these elements? Both for non-online and online versions of this question. Thank you! Edit The non-online version I was referring to is: this array is specified in full. The online version means the array elements are coming one at a time. I require the space in addition to time complexity to be tight. disclaimer: THIS IS NOT HOMEWORK! I consider this as research-level question.

• Why does this Bash regex match return an Exit Status of "2"?

  - by PreservedMoose

  I'm writing a Bash script that needs to scan for the existence of non-ASCII characters in filenames. I'm using the POSIX bracket regex syntax to match the non-ASCII characters, but for some reason, when I test for the match in an if/then statement, the test always returns an Exit Status of 2, and never matches my test string. Here's the code in question: FILEREQ_SOURCEFILE="Filename–WithNonAScII-Charàcters-05sec_23.98.mov" REGEX_MATCH_NONASCII="[^[:ascii:]]" if [[ $FILEREQ_SOURCEFILE =~ $REGEX_MATCH_NONASCII ]]; then echo "Exit Status: $?" echo "Matched!" else echo "Exit Status: $?" echo "No Match" fi This code always returns: Exit Status: 2 No Match I've read and re-read the bash-hackers.org explanation of how regex matching works, as well as this previous question on SO regarding matching non-ASCII characters, but for the life of me, I can't get this to work. What am I missing here?

• Path Inclusion/Global variable not working?

However I still come up with: Undefined variable db. Anything you guys are seeing I'm not? Thanks! Let me know if more details are needed.
