• T-SQL stored procedure to return google style "suggested" search results

  - by stephen776

  Ok, using SQL Server 2008. On my web page I have a textbox with jQuery-UI AutoComplete hooked up. Now I need a stored procedure to search across all columns of a single table(or multiple joined tables I suppose) for a search string coming from the textbox/autocomplete AJAX call, and return "suggested" search strings. I am using the AdventureWorks db for testing(Products table) So for example, the product table has columns for product name and product number(among others) and I want to return suggested search strings based on user input where they may enter a product name and/or a product number. I have it working across a single column which was simple. Any ideas?

• What is a good measure of strength of a link and influence of a node?

  - by Legend

  In the context of social networks, what is a good measure of strength of a link between two nodes? I am currently thinking that the following should give me what I want: For two nodes A and B: Strength(A,B) = (neighbors(A) intersection neighbors(B))/neighbors(A) where neighbors(X) gives the total number of nodes directly connected to X and the intersection operation above gives the number of nodes that are connected to both A and B. Of course, Strength(A,B) != Strength(B,A). Now knowing this, is there a good way to determine the influence of a node? I was initially using the Degree Centrality of a node to determine its "influence" but I somehow think its not a good idea because just because a node has a lot of outgoing links does not mean anything. Those links should be powerful as well. In that case, maybe using an aggregate of the strengths of each node connected to this node is a good idea to estimate its influence? I'm a little confused. Does anyone have any suggestions?

• Dynamically add rows to listbox

  - by Ivan S

  I have a list box that displays information off of a column of a dataset. I would like the number of rows displayed to be all the rows that are in the dataset (the number of datasets in the rows vary). I'm figuring it has something to do with ListBox.Rows = Dataset.Tables[0].Rows.Count; But it seems to just always default to 4 even when it is only 2. This is what I have in my aspx.cs file. pirateBox.DataTextField = Pirateship.Tables[0].Columns["displayName"].ToString(); pirateBox.DataValueField = pirateship.Tables[0].Columns["PKID"].ToString(); pirateBox.DataSource = pirateship.Tables[0]; pirateBox.DataBind(); pirateBox.Rows = pirateship.Tables[0].Rows.Count; I've been trying a few things and this is what I have so far in .aspx <asp:ListBox ID="pirateBox" runat="server" Rows="1"></asp:ListBox>

• ActionScript display zero value

  - by bwong

  It seems the number Datatype handles zeros and nulls the same. I need to display a zero value on the screen, but AS displays nothing. When it's saved, the value is saved as a zero, and therefore shows up zero on the screen. Is there a way to display the zero value using a new object? public class myObject{ private var numVar:Number } My AS file: var temp:MyObject temp.numVar = 0; When I debug, temp.numVar contains a value of 0, but does not show anything on the UI. If this object is then saved to the DB, and then displayed to the UI, it shows a 0. My question is - how do I get temp.numVar to display 0 before persistenting it to the DB?

• Automatically taking screenshots of program window

  - by Sergey Kornilov

  I'm looking for a software that combines macro recording with screenshot taking capabilities. We have a software manual with a number of screenshots. When new version of software is released we need to update most of screenshots and we have to do it manually. Now we started translating manual to several languages and number of screenshots to take have increased ten fold. We'd like to automate this process. There will be a recorded macro or something that clicks button within our software and takes screenshots of the program window. Better yet, we can specify the name of each screenshot individually though it's less important. Does such a thing exist?

• PHP no wait sem_acquire?

  - by SerEnder

  Not a specific code question, but more of a general coding question. I'm trying to use a semaphore in a work project to limit the number of users that can access certain processes at a concurrent time. From my understanding the following: $iKey = ftock($sSomeFileLocation,'sOneCharacterString'); //Generate the key if($sem_id = sem_get($iKey){ //1 user allowed if(sem_acquire($sem_id)){ //Do the limited process here sem_release($sem_id); } } The problem that I see here is that if there is already one user who has the semaphore key, then the next user just waits until the first user is done rather than just faulting out. Anyone know of a way that if the max_acquire number has been reached, sem_acquire (or similar) will just return false? Thanks

  Heading Is there a way to map an arbitrary string to a HEX COLOR code. I tried to compute the HEX number for string using string hashcode. Now I need to convert this hex number to six digits which are in HEX color code range. Any suggestions ? String [] programs = {"XYZ", "TEST1", "TEST2", "TEST3", "SDFSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSS"}; for(int i = 0; i < programs.length; i++) { System.out.println( programs[i] + " -- " + Integer.toHexString(programs[i].hashCode())); }

• Find all those columns which have only null values, in a MySQL table

  - by Robin v. G.

  The situation is as follows: I have a substantial number of tables, with each a substantial number of columns. I need to deal with this old and to-be-deprecated database for a new system, and I'm looking for a way to eliminate all columns that have - apparently - never been in use. I wanna do this by filtering out all columns that have a value on any given row, leaving me with a set of columns where the value is NULL in all rows. Of course I could manually sort every column descending, but that'd take too long as I'm dealing with loads of tables and columns. I estimate it to be 400 tables with up to 50 (!) columns per table. Is there any way I can get this information from the information_schema? EDIT: Here's an example: column_a column_b column_c column_d NULL NULL NULL 1 NULL 1 NULL 1 NULL 1 NULL NULL NULL NULL NULL NULL The output should be 'column_a' and 'column_c', for being the only columns without any filled in values.

• too many threads due to synch communication

  - by MasoudIzzy

  I'm using threads and xmlrpclib in python at the same time. Periodically, I create a bunch of thread to complete a service on a remote server via xmlrpclib. The problem is that, there are times that the remote server doesn't answer. This causes the thread to wait forever for a response which it never gets. Over time, number of threads in this state increases and will reach the maximum number of allowed threads on the system (I'm using fedora). I tried to use socket.setdefaulttimeout(10); but the exception that is created by that will cause the server to defunct. I used it at server side but it seems that it doesn't work :/ Any idea how can I handle this issue?

• How to test a regex password in Python?

  - by jCuga

  Using a regex in Python, how can I verify that a user's password is: At least 8 characters Must be restricted to, though does not specifically require any of: uppercase letters: A-Z lowercase letters: a-z numbers: 0-9 any of the special characters: @#$%^&+= Note, all the letter/number/special chars are optional. I only want to verify that the password is at least 8 chars in length and is restricted to a letter/number/special char. It's up to the user to pick a stronger / weaker password if they so choose. So far what I have is: import re pattern = "^.*(?=.{8,})(?=.*\d)(?=.*[a-z])(?=.*[A-Z])(?=.*[@#$%^&+=]).*$" password = raw_input("Enter string to test: ") result = re.findall(pattern, password) if (result): print "Valid password" else: print "Password not valid"

• Uniforme distance between points

  - by Reonarudo

  Hello, How could I, having a path defined by several points that are not in a uniform distance from each other, redefine along the same path the same number of points but with a uniform distance. I'm trying to do this in Objective-C with NSArrays of CGPoints but so far I haven't had any luck with this. Thank you for any help. EDIT I was wondering if it would help to reduce the number of points, like when detecting if 3 points are collinear we could remove the middle one, but I'm not sure that would help.

• Does the order of conditions in a WHERE clause affect MySQL performance?

  - by Greg

  Say that I have a long, expensive query, packed with conditions, searching a large number of rows. I also have one particular condition, like a company id, that will limit the number of rows that need to be searched considerably, narrowing it down to dozens from hundreds of thousands. Does make any difference to MySQL performance whether I do this: SELECT * FROM clients WHERE (firstname LIKE :foo OR lastname LIKE :foo OR phone LIKE :foo) AND (firstname LIKE :bar OR lastname LIKE :bar OR phone LIKE :bar) AND company = :ugh or this: SELECT * FROM clients WHERE company = :ugh AND (firstname LIKE :foo OR lastname LIKE :foo OR phone LIKE :foo) AND (firstname LIKE :bar OR lastname LIKE :bar OR phone LIKE :bar)

• Deleting Part of An Array in Java to Free Memory on Heap

  - by kate

  I am implementing a dynamic programming algorithm for the knapsack problem in Java. I declare the array and then initialize its size to be [number of objects][capacity of knapsack]. When my number of objects or my capacity gets too large, I get a memory error because I run out of space on the heap. My questions is: If I delete rows from my double array as I go along, will Java free the memory as I delete? Or does Java reserve that memory space for the size of the array I originally created? If it's the latter, is there a way to manually free the memory in Java? Thanks for your Help!

• Javascript Phone Swap

  - by Batfan

  I've been trying to find a way to do this but, have not found many resources that specifically relate to this situation. I need a javascript (can make use of Jquery if need be) to swap phone numbers on a site. 2 numbers would be specified. One would show on the site by default. The script needs to be able to create a cookie and do this by recognizing a value in the URL string. For Example: http://www.site.com/index.html?value= '?value=' would be the value. This URL (with the additional variable) would bring the user to the same site but, the variable in the string would set the cookie and display a different number. The default number would not be displayed again until the cookies were removed. Due to the situation with my server, I cannot make use of PHP ( I know, that would make things alot easier :P ) Any help would be greatly appreciated.

• Using variables within Attributes in C#

  - by tehp

  We have some Well-Attributed DB code, like so: [Display(Name = "Phone Number")] public string Phone { get; set; } Since it is quite generic we'd like to use it again, but with a different string in the Name part of the attribute. Since it's an attribute it seems to want things to be const, so we tried: const string AddressType = "Student "; [Display(Name = AddressType + "Phone Number")] public string Phone { get; set; } This seems to work alright, except that having a const string means we can't overwrite it in any base classes, thereby removing the functionality that we originally were intending to add, and exposing my question: Is there a way to use some sort of variable inside of an attribute so that we can inherit and keep the attribute decorations?

• Ideas on limiting content to single printed page?

  - by James Skidmore

  I have 5-6 text areas that users fill out in a template (a couple of columns, basically a newsletter format). I'm needing to limit their content to one printed page, but I'm having a hard time coming up with practical solutions. The printed format (margin, font size, etc.) will be the same for all users, as it's printed from a central source. I've had a couple of ideas, but all of them seem rather unreliable and difficult to implement: Determine height of content using JavaScript and estimate the number of printed pages from that. The problem with this is that browser font sizes can vary, it's only a rough estimate (pixels to inches), etc. Limit the number of characters. This is problematic because there are various text fields, certain characters (like M) take up more space than others (like I), and line breaks obviously count for much more. What ideas do you all have? I appreciate your help!

• Is C# compiler not reporting all errors at once at each compile?

  - by Joan Venge

  When I am compiling this project, it show like 400+ errors in the Error List window, then I go to error sites, fix some, and the number goes to say 120+ errors, and then after fixing some more, the next compile reports like 400+ again. I can see that different files are coming in in the Error List window, so I am thinking the compiler aborts after a certain number of errors? If so, what's the reason for this? Is it not supposed to gather all the errors that are present in the project even if they are over 10K+?
