  • How to group strings by prefix

    - by namenlos
    I am writing a Winform UI in which the user must select a single customer. (For reasons beyond my control I am limited to a UI that uses dropdown lists, text fields, checkboxes, radiobuttons only -i.e. no fancy special UI controls) The situation There are a lot of customers (a thousand for example) If i put all the customers in a single dropdown there's no way it will be easy for a customer to even see all the customers. Also the it will take too long to retireve all the customers from the DB to populate the dropdown My thought is to have two combo box, the first lists groups of the customers by their last name something like a phone book "Aa-Ac", "Ad-Ade", "Adf-B", when selecting the first combo box, it scope the second one to a managable set customer names (no more than for example 40 names) The question I need a reasonable way of grouping their names such that it will be clear to customer which group contains the name. I.e. given a group of names I need to bucketize then int "Aa-Ac". Comments I don't need to solve the general problem of an immense number of names - we know based on our data that 1000 names is the max our users will encounter. If there are other techniques please do share, but I am interested specifically in an answer to my specific question around how to determine the buckets ("Aa-Ac", etc.)

  • Ruby concatenate strings and add spaces

    - by David Oneill
    I have 4 string variables name, quest, favorite_color, speed that might be empty. I want to concatenate them all together, putting spaces between those that aren't empty. So: name = 'Tim' quest = 'destroy' favorite_color = 'red' speed = 'fast' becomes 'Tim destroy red fast' and name = 'Steve' quest = '' favorite_color = '' speed = 'slow' becomes: 'Steve slow' (Notice: there is only 1 space between 'Steve' and 'slow') How do I do that (preferably in 1 line).

  • Showing HTML comment strings (<!-- -->) in HTML files

    - by Andrei
    Hello all. I'm building a source code search engine, and I'm returning the results on a HTML page (aspx to be exact, but the view logic is in HTML). When someone searches a string, I also return the whole line of code where this string can be found in a file. However, some lines of code come from HTML/aspx files and these lines contain HTML specific comments (). When I try to print this line on the HTML page, it interprets it as a comment and does not show it on the screen....how should I go about solving this so that it actually shows up? Any help would be welcomed. Thanks. edit: err...i see now that firebug could help me with this: <!-- -->

  • Using regexkitlite with strings containing % signs

    - by David Liu
    So I'm using RegexKitLite in my iPhone app, and I'm basically grabbing out a bunch of URLs and names from within a web page. The problem is that whenever it comes across a URL with URL encoded characters like %22 for a double quote or %27 for a single quote, the captured string basically gives me a jumbled overflowed string, containing garbage and even method names. I'm really not doing anything particularly special within the regex, just your basic "startdelimiter(.*)enddelimiter" regex.

  • How can I quote strings in SASS?

    - by Stavros Korokithakis
    I'm using SASS to generate a @font-face mixin, however this: =remotefont(!name, !url) @font-face font-family = !name src = url(!url + ".eot") src = local(!name), url(!url + ".ttf") format("truetype") +remotefont("My font", "/myfont.ttf") becomes this: @font-face { font-family: My font; src: url(/myfont.ttf.eot); src: local(My font), url(/myfont.ttf.ttf) format(truetype); } No matter how much I try, I can't have it quote either "My font" (with "!name") or "truetype" (it removes the quotes). Any ideas on how I can do this?

  • Winforms connection strings from App.config

    - by Geo Ego
    I have a Winforms app that I am developing in C# that will serve as a frontend for a SQL Server 2005 database. I rolled the executable out to a test machine and ran it. It worked perfectly fine on the test machine up until the last round of changes that I made. However, now on the test machine, it throws the following exception immediately upon opening: System.NullReferenceException: Object reference not set to an instance of an object. at PSRD_Specs_Database_Administrat.mainMenu.mainMenu_Load(Object sender, EventArgs e) at System.Windows.Forms.Form.OnLoad(EventArgs e) at System.Windows.Forms.Form.OnCreateControl() at System.Windows.Forms.Control.CreateControl(Boolean fIgnoreVisible) at System.Windows.Forms.Control.CreateControl() at System.Windows.Forms.Control.WmShowWindow(Message& m) at System.Windows.Forms.Control.WndProc(Message& m) at System.Windows.Forms.ScrollableControl.WndProc(Message& m) at System.Windows.Forms.ContainerControl.WndProc(Message& m) at System.Windows.Forms.Form.WmShowWindow(Message& m) at System.Windows.Forms.Form.WndProc(Message& m) at System.Windows.Forms.Control.ControlNativeWindow.OnMessage(Message& m) at System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m) at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam) The only thing that I changed in this version that pertains to mainMenu_Load is the way that the connection string to the database is called. Previously, I had set a string with the connection string on every form that I needed to call it from, like: string conString = "Data Source = SHAREPOINT;Trusted_Connection = yes;" + "database = CustomerDatabase;connection timeout = 15"; As my app grew and I added forms to it, I decided to add an App.config to the project. I defined the connection string in it: <connectionStrings> <add name="conString" providerName="System.Data.SqlClient" connectionString="Data Source = SHAREPOINT;Trusted_Connection = yes;database = CustomerDatabase;connection timeout = 15" /> </connectionStrings> I then created a static string that would return the conString: public static string GetConnectionString(string conName) { string strReturn = string.Empty; if (!(string.IsNullOrEmpty(conName))) { strReturn = ConfigurationManager.ConnectionStrings[conName].ConnectionString; } else { strReturn = ConfigurationManager.ConnectionStrings["conString"].ConnectionString; } return strReturn; } I removed the conString variable and now call the connection string like so: PublicMethods.GetConnectionString("conString").ToString() It appears that this is giving me the error. I changed these instances to directly call the connection string from App.config without using GetConnectionString. For instance, in a SQLConnection: using (SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["conString"].ConnectionString)) This also threw the exception. However, when I went back to using the conString variable on each form, I had no issues. What I don't understand is why all three methods work fine on my development machine, while using the App.config directly or via the static string I created throw exceptions.

  • Selecting arbitrary strings with Zend DB Select?

    - by wizzard
    I am using the fluent interface to create a Zend DB Select object/query. As part of the query, I would like to select an arbitrary string, like "SELECT 'foo' AS 'type' FROM ...". foo is not a column, it's just a string literal. When I select an arbitrary number, the query works as expected. When I change it to a string, Zend tries to treat foo as a column, and throws an error: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'l.foo' in 'field list' I have tried wrapping the string in Zend_Db_Expr in various ways such as: $select->columns(array('type' => new Zend_Db_Expr('foo'))); That stops Zend from adding the correlation name, but it still treats it as a column: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'foo' in 'field list' I feel like I must be missing something obvious here. How do I tell Zend to stop treating this as a column?

  • Insert unicode strings into CleverCSS

    - by Brian M. Hunt
    How can one insert a Unicode string CSS into CleverCSS? In particular, how could one produce the following CSS using CleverCSS: li:after { content: "\00BB \0020"; } I've figured out CleverCSS's parsing rules, but suffice that the permutations I've thought sensible have failed, for example: li: content: "\\00BB \\0020" // becomes content: 'BB 0' EDIT: My other examples and the rest of my post weren't saved. Suffice that I had a longer list of examples that also failed, as did my closing which was something like: I'd be grateful for any thoughts and input. Brian

  • Separating Strings from a CSV File in SSIS 2008

    - by David Stein
    I have data which resembles the following: "D.STEIN","DS","01","ALTRES","TTTTTTFFTT" "D.STEIN","DS","01","APCASH","TTTTTTFFTT" "D.STEIN","DS","01","APINH","TTTTTTFFTT" "D.STEIN","DS","01","APINV","TTTTTTFFTT" "D.STEIN","DS","01","APMISC","TTTTTTFFTT" "D.STEIN","DS","01","APPCHK","TTTTTTFFTT" "D.STEIN","DS","01","APWLNK","TTTTTTFFTT" "D.STEIN","DS","01","ARCOM","TTTTTTFFTT" "D.STEIN","DS","01","ARINV","TTTTTTFFTT" I need to break out the final string into separate columns for import into a SQL Table, one letter into each field. Therefore, "TTTTTTFFTT" will be broken out into 10 separate fields each with a single bit value. I've used a Flat File Source Editor to load the data. How do I accomplish the split?

  • Adding lengths of strings together in Ruby

    - by ppreyer
    I'm trying to write a program that takes the length of my first, middle, and last names individually and then adds the total amount of letters up in the end. My answer keeps on being 666 instead of 18. Here is the code I have written: puts 'What is your first name?' firstName = gets.chomp realFirstName = firstName.length.to_i puts 'What is your middle name?' middleName = gets.chomp realMiddleName = middleName.length.to_i puts 'What is your last name?' lastName = gets.chomp realLastName = lastName.length.to_i puts 'Did you know there are ' + realFirstName.to_s + realMiddleName.to_s + realLastName.to_s + ' letters in your name?' Just wondering where I went wrong.

  • Java, LinkedList of Strings. Insert in alphabetical order

    - by user69514
    I have a simple linked list. The node contains a string (value) and an int (count). In the linkedlist when I insert I need to insert the new Node in alphabetical order. If there is a node with the same value in the list, then I simply increment the count of the node. I think I got my method really screwed up. public void addToList(Node node){ //check if list is empty, if so insert at head if(count == 0 ){ head = node; head.setNext(null); count++; } else{ Node temp = head; for(int i=0; i<count; i++){ //if value is greater, insert after if(node.getItem().getValue().compareTo(temp.getItem().getValue()) > 0){ node.setNext(temp.getNext()); temp.setNext(node); } //if value is equal just increment the counter else if(node.getItem().getValue().compareTo(temp.getItem().getValue()) == 0){ temp.getItem().setCount(temp.getItem().getCount() + 1); } //else insert before else{ node.setNext(temp); } } } }

  • Checking for Repeated Strings in 2d list

    - by Zach Santiago
    i have a program where i have a list of names and classes. i have the list in alphabetical order. now im trying to check if names repeat, add the classes to one single name. im trying to write some code like go through names if name is already in list, add the class to the one name. so an example would be, instead of having 'Anita ','phys 1443', and 'Anita','IE 3312' i would just have 'Anita','PHYS 1443','IE 3312'. How would i go about doing this in a logival way, WITHOUT using any sort of built in functions? i tried comparing indexe's like if list[i][0] == list[i+1][0], append list[i+1][1] to an emptylist. while that almost worked, it would screw up at some points along the way. here is my attempt size = len(c) i = 0 c = [['Anita', 'PHYS 1443'], ['Anita', 'IE 3312'], ['Beihuang', 'PHYS 1443'], ['Chiao-Lin', 'MATH 1426'], ['Chiao-Lin', 'IE 3312'], ['Christopher', 'CSE 1310'], ['Dylan', 'CSE 1320'], ['Edmund', 'PHYS 1443'], ['Ian', 'IE 3301'], ['Ian', 'CSE 1320'], ['Ian', 'PHYS 1443'], ['Isis', 'PHYS 1443'], ['Jonathan', 'MATH 2325'], ['Krishna', 'MATH 2325'], ['Michael', 'IE 3301'], ['Nang', 'MATH 2325'], ['Ram', 'CSE 1320'], ['Taesu', 'CSE 1320'], ["Tre'Shaun", 'IE 3312'], ["Tre'Shaun", 'MATH 2325'], ["Tre'Shaun", 'CSE 1310']] ## Check if any names repeat d.append(c[0][0]) while i < size - 1 : if c[i][0] == c[i+1][0] : d.append(c[i][1]) d.append(c[i+1][1]) else : d.append(c[i+1][0]) d.append(c[i+1][1]) i = i + 1 print d output was. ['Anita', 'PHYS 1443', 'IE 3312', 'Beihuang', 'PHYS 1443', 'Chiao-Lin', 'MATH 1426', 'MATH 1426', 'IE 3312', 'Christopher', 'CSE 1310', 'Dylan', 'CSE 1320', 'Edmund', 'PHYS 1443', 'Ian', 'IE 3301', 'IE 3301', 'CSE 1320', 'CSE 1320', 'PHYS 1443', 'Isis', 'PHYS 1443', 'Jonathan', 'MATH 2325', 'Krishna', 'MATH 2325', 'Michael', 'IE 3301', 'Nang', 'MATH 2325', 'Ram', 'CSE 1320', 'Taesu', 'CSE 1320', "Tre'Shaun", 'IE 3312', 'IE 3312', 'MATH 2325', 'MATH 2325', 'CSE 1310']

  • How to handle HTML Strings in Cocoa Touch

    - by balexandre
    I'm using a RSS Reader and works fine when I tap the UITableViewCell to load the <link> either in a UIWebView or to open Safari on that link. But I really want to learn how to load the Topic content into the application instead showing the entire site or jump to Safari In the RSS feed per each <item> there is a <body> tag (and a <Description> that contains the same but encoded) that contains the topic content, like the image below shows: So, instead of catching the <link> I'm assigning the <body>. Problem is that it does not work correctly :-( for this example I only get the content until the first <br> nothing more. I'm using a NSString as I would use in C#, should I use any other object, is there a better object to use on such data? Should I use an UITextView to load this information (as it has scroll already) or I should use a UIWebView instead? Thank you.
