• Javascript Grid that can handle sections in a table

  - by user335410

  I am making an ASP.NET MVC application that lets a user design a questionnaire that other users can fill out. Now, questionnaires, rather than just having a list of questions, often have sections or subsections that could have headings and not the other columns that an ordinary row (a question) would have. I want a JS Grid that can handle sections and subsections elegantly. I tried using JQGrid, but there the options I have are limited to a "Grid as Subgrid" structure. The appearance becomes quite complex and unlike a questionnaire. Is there a Javascript Grid or a JQuery plugin that can handle this? I can write my own HTML table as long as the JS app will format the table and will add some user-friendliness to the table.

• Random List of millions of elements in Python Efficiently

  - by eWizardII

  Hello, I have read this answer potentially as the best way to randomize a list of strings in Python. I'm just wondering then if that's the most efficient way to do it because I have a list of about 30 million elements via the following code: import json from sets import Set from random import shuffle a = [] for i in range(0,193): json_data = open("C:/Twitter/user/user_" + str(i) + ".json") data = json.load(json_data) for j in range(0,len(data)): a.append(data[j]['su']) new = list(Set(a)) print "Cleaned length is: " + str(len(new)) ## Take Cleaned List and Randomize it for Analysis shuffle(new) If there is a more efficient way to do it, I'd greatly appreciate any advice on how to do it. Thanks,

• Best practices for handling string in VC++?

  - by Hiren Gujarati

  As I am new to Visual C++, there are so many types for handling string. When I use some type and go ahead with coding but on next step, there are in-build functions that use other types & it always require to convert one type of string to other. I found so many blogs but so confused when see so many answers & try but some are working & some are not. Please give your answer or links that gives ultimate solution for handling different types of strings in visual c++.

• Large tables of static data with DBGhost

  - by Paulo Manuel Santos

  We are thinking of restructuring our database development and deployment processes by using DBGhost, we want to move away from the central development database and bring the database to the source control. One of the problems we have is a big table with static data (containing translated language strings), it has close to 200K rows. I know that our best solution is to move these stings into resource files, but until we implement that, will DbGhost be able to maintain all this static data and generate our development and deployment databases in a short time? And if not is there a good alternative to filling up this table whenever we need to?

• Read a file address from a txt file using netbeans c

  - by Yadira Suazo

  Hi everybody. I`m having problems reading a file address from a txt file. The information seems to be corrupted when I watch it in the debugger. The code is FILE *parch; const char * vectorparch[50]; //array with 50 file paths parch = fopen("/home/irmay/NetBeansProjects/neurona/patrones/patrones.txt", "r"); for(j=0;j<50;j++){ fread ( vectorparch, sizeof ( char ), 50, parch ); propagar(vectorparch[j]); } fclose(parch); The file with paths has 50 strings is like this: "/home/irmay/NetBeansProjects/neurona/patrones/10_0.txt","/home/..." The function propagar is declared void propagar (const char * arch1) Thank you.

• WPF - Correct Syntax for Using Coverter with Current Binding

  - by Andy T

  Hi, I have a collection of hex strings that represent colours and I am binding a combobox's ItemsSource to that collection. The combobox items are templated to have a filled rectangle with the relevant colour. I therefore need to use a converter to convert the hex value to a string. Easy enough. However, Blend is telling me that this syntax is incorrect in my XAML: Fill="{Binding, Converter={StaticResource StringToBrush}}" Apparently, I can't use a converter against plain old 'Binding'. Blend says that something like this is syntactically correct: Fill="{Binding Value, Converter={StaticResource StringToBrush}}" ...However that obviously doesn't work. I'm not quite au fait with binding syntax yet, so obviously I'm getting it wrong. Can anyone advise the correct syntax to achieve what I'm trying to do (convert my bound String using the coverter StringToBrush)? Thanks in advance! AT

• How Do I Remove The First 4 Characters From A String If It Matches A Pattern In Ruby

  - by James

  I have the following string: "h3. My Title Goes Here" I basically want to remove the first 4 characters from the string so that I just get back: "My Title Goes Here". The thing is I am iterating over an array of strings and not all have the h3. part in front so I can't just ditch the first 4 characters blindly. I have checked the docs and the closest think I could find was chomp, but that only works for the end of a string. Right now I am doing this: "h3. My Title Goes Here".reverse.chomp(" .3h").reverse This gives me my desired output, but there has to be a better way right? I mean I don't want to reverse a string twice for no reason. I am new to programming so I might have missed something obvious, but I didn't see the opposite of chomp anywhere in the docs. Is there another method that will work? Thanks!

• Is it bad practice to use python's getattr extensively?

  - by Wilduck

  I'm creating a shell-like environment. My original method of handleing user input was to use a dictionary mapping commands (strings) to methods of various classes, making use of the fact that functions are first class objects in python. For flexibility's sake (mostly for parsing commands), I'm thinking of changing my setup such that I'm using getattr(command), to grab the method I need and then passing arguments to it at the end of my parser. Another advantage of this approach is not having to update my (currently statically implemented) command dictionary every time I add a new method/command. My question is, will I be taking a hit to the efficiency of my shell? Does it matter how many methods/commands I have? I'm currently looking at 30 some commands, which could eventually double.

• PHP Framework / Library Suggestions for a Backend

  - by frbry

  I am about to start to developing backend site of a php project. Companies and site admins will login to this site and manage their data on the project. My previous admin panel experiences were full of agony and pain. So I want to make sure that I choose correct tools for my purpose. By the way, please note, I'm not looking for scaffolding. There won't be much tables in my database. Instead, there will be complex logic between entities. I want clear seperation of markup and logic code and easy-to-use and standardized user-interface. Thank you.

• saving a records containing a member of type string to a file (Delphi, Windows)

  - by wonderer

  I have a record that looks similar to: type TNote = record Title : string; Note : string; Index : integer; end; Simple. The reason I chose to set the variables as string (as opposed to an array of chars) is that I have no idea how long those strings are going to be. They can be 1 char long, 200 or 2000. Of course when I try to save the record to a type file (file of...) the compiler complains that I have to give a size to string. Is there a way to overcome this? or a way to save those records to an untyped file and still maintain a sort of searchable way? Please do not point me to possible solutions, if you know the solution please post code. Thank you

• Applying a pixel shader effect to a portion of an image

  - by Nick

  I have a ScrollViewer that contains a very large video (16 megapixel @ 10fps) and I want to apply a pixel shader effect to it. Given the size of the images I can't apply the effect directly to the image. So I apply the effect to the ScrollContentPresenter in the control style. Which is great, everything runs nice and fast. However, I'm also rendering annotations inside of the ScrollContentPresenter which I do NOT want effects applied to (but they need to move and scale along with the image). Is there to apply the effect just to the clipped and displayed portion of the image or do I need to build a rather more complex control?

• Is there a web site where I can paste a SQL Insert statement and have it break it out by column?

  - by Scott Whitlock

  I've been working on an application that has no discernable data access layer, so all the SQL statements are just built up as strings and executed. I'm constantly confronted by very long INSERT statements where I'm trying to figure out what value in the VALUES list matches up with what column in the column name list. I was about to create a little helper application where I could paste in an INSERT statement and have it show me a list of values matched up with the column names, just for debugging, and I thought, "someone else has probably done this already." Does anyone know of a web site where I can just paste in an INSERT statement and have it show me a two column table with column names in the first column and values in the second column?

• Store time of the day in SQL

  - by nute

  How would you store a time or time range in SQL? It won't be a datetime because it will just be let's say 4:30PM (not, January 3rd, 4:30pm). Those would be weekly, or daily meetings. The type of queries that I need are of course be for display, but also later will include complex queries such as avoiding conflicts in schedule. I'd rather pick the best datatype for that now. I'm using MS SQL Server Express 2005. Thanks! Nathan

• How can I consume a WSDL (SOAP) web service in Python?

  - by DavidM

  I want to use a WSDL SOAP based web service in Python. I have looked at the Dive Into Python code but the SOAPpy module does not work under Python 2.5. I have tried using suds which works partly, but breaks with certain types (suds.TypeNotFound: Type not found: 'item'). I have also looked at Client but this does not appear to support WSDL. And I have looked at ZSI but it looks very complex. Does anyone have any sample code for it? The WSDL is https://ws.pingdom.com/soap/PingdomAPI.wsdl and works fine with the PHP 5 SOAP client.

• Extract multiple values from one column in MySql

  - by Neil

  I've noticed that MySql has an extensive search capacity, allowing both wildcards and regular expressions. However, I'm in somewhat in a bind since I'm trying to extract multiple values from a single string in my select query. For example, if I had the text "<span>Test</span> this <span>query</span>", perhaps using regular expressions I could find and extract values "Test" or "query", but in my case, I have potentially n such strings to extract. And since I can't define n columns in my select statement, that means I'm stuck. Is there anyway I could have a list of values (ideally separated by commas) of any text contained with span tags? In other words, if I ran this query, I would get "Test,query" as the value of spanlist: select <insert logic here> as spanlist from HtmlPages ...

• How to build the ViewModel in MVVM not to violate the Single Responsibility Principle?

  - by Przemek

  Robert Martin says: "There should never be more than one reason for a class to change". Let's consider the ViewModel class which is bound to a View. It is possible (or even probable) that the ViewModel consists of properties that are not really related to each other. For small views the ViewModel may be quite coherent, but while the application gets more complex the ViewModel will expose data that will be subject to change for different and unrelated reasons. Should we worry about the SRP principle in the case of ViewModel class or not?

• Repeating a List in Scala

  - by Ralph

  I am a Scala noob. I have decided to write a spider solitaire solver as a first exercise to learn the language and functional programming in general. I would like to generate a randomly shuffled deck of cards containing 1, 2, or 4 suits. Here is what I came up with: val numberOfSuits = 1 (List["clubs", "diamonds", "hearts", "spades"].take(numberOfSuits) * 4).take(4) which should return List["clubs", "clubs", "clubs", "clubs"] List["clubs", "diamonds", "clubs", "diamonds"] List["clubs", "diamonds", "hearts", "spades"] depending on the value of numberOfSuits, except there is no List "multiply" operation that I can find. Did I miss it? Is there a better way to generate the complete deck before shuffling? BTW, I plan on using an Enumeration for the suits, but it was easier to type my question with strings. I will take the List generated above and using a for comprehension, iterate over the suits and a similar List of card "ranks" to generate a complete deck.

• Kerning problems when drawing text character by character

  - by shekel

  I'm trying to draw strings character by character to add lighting effects to shapes composed of text. while (i != line.length()) { c = line.substring(i, i + 1); cWidth = g.getFontMetrics().stringWidth(c); g.drawString(c, xx += cWidth, yy); i++; } The problem is, the width of a character isn't the actual distance it's drawn from another character when those two characters are printed as a string. Is there any way to get the correct distance in graphics2d?

• creating an options menu with quit application function

  - by Domen Tomažin

  Hello, I'm writing an application for android and I would like to insert an options menu, that would have only one function and that is to quit an application. My options_menu.xml looks like this (I created a new folder under res called menu - just like the instructions said): Than I added the following code to my java class file: @Override public boolean onCreateOptionsMenu(Menu menu) { MenuInflater inflater = getMenuInflater(); inflater.inflate(R.menu.options_menu, menu); return true; } @Override public boolean onOptionsItemSelected(MenuItem item) { // Handle item selection switch (item.getItemId()) { case R.id.quit: finish(); return true; default: return super.onOptionsItemSelected(item); } I also defined the @string/quit in values - strings.xml file, but it still says that there is an error: C:\Users\Domen\workspace\Lovne Dobe1.1\res\menu\options_menu.xml:3: error: Error: No resource found that matches the given name (at 'title' with value '@string/quit') So if anybody can help I would be very grateful.

• PyParsing: Is this correct use of setParseAction()?

  - by Rosarch

  I have strings like this: "MSE 2110, 3030, 4102" I would like to output: [("MSE", 2110), ("MSE", 3030), ("MSE", 4102)] This is my way of going about it, although I haven't quite gotten it yet: def makeCourseList(str, location, tokens): print "before: %s" % tokens for index, course_number in enumerate(tokens[1:]): tokens[index + 1] = (tokens[0][0], course_number) print "after: %s" % tokens course = Group(DEPT_CODE + COURSE_NUMBER) # .setResultsName("Course") course_data = (course + ZeroOrMore(Suppress(',') + COURSE_NUMBER)).setParseAction(makeCourseList) This outputs: >>> course.parseString("CS 2110") ([(['CS', 2110], {})], {}) >>> course_data.parseString("CS 2110, 4301, 2123, 1110") before: [['CS', 2110], 4301, 2123, 1110] after: [['CS', 2110], ('CS', 4301), ('CS', 2123), ('CS', 1110)] ([(['CS', 2110], {}), ('CS', 4301), ('CS', 2123), ('CS', 1110)], {}) Is this the right way to do it, or am I totally off? Also, the output of isn't quite correct - I want course_data to emit a list of course symbols that are in the same format as each other. Right now, the first course is different from the others. (It has a {}, whereas the others don't.)

• Why does overflow:hidden not work in a <td>?

  - by mike

  I've got a table cell that I would always like to be a particular width. However, it doesn't work with large strings of unspaced text. Here's a test case: <html><body> <table><tbody><tr> <td style="border: solid green 1px; width:200px; overflow:hidden;"> This_is_a_terrible_example_of_thinking_outside_the_box. </td> </tr></tbody></table> </body></html> How do I get the text to be cut off at the edge of the box, rather than having the box expanded?

• Convert an XML object back into a string in ColdFusion

  - by jpmyob

  In ColdFusion, I can parse a string of XML formatted data into an XML Object using xmlParse(). How can I convert it back into a string? When I tried using toString() it throws an error that "it can't convert complex object to simple objects....", which is ironic because that's what it's supposed to do. I need to use XMLTransform() which requires the first argument to be an xml string. But I also need to use xmlSearch() to get a node to pass into my transform, and xmlSearch returns an xmlObject. So now I need to put that object back into xml string format to pass into xmlTransform.

• Returning from method inside a @synchronized block

  - by Michael Waterfall

  I'd just like to know if it's advised to return from a method within a @synchronized block? For example: - (id)test { @synchronized(self) { if (a) return @"A"; else return @"B"; } } As opposed to: - (id)test { NSString *value; @synchronized(self) { if (a) value = @"A"; else value = @"B"; } return value; } This sample is rather simplistic, but sometimes in a complex method it would make things simpler to be able to return from within a @synchronized block.

• How do I ignore the UTF-8 Byte Order Marker in String comparisons?

  - by Skrud

  I'm having a problem comparing strings in a Unit Test in C# 4.0 using Visual Studio 2010. This same test case works properly in Visual Studio 2008 (with C# 3.5). Here's the relevant code snippet: byte[] rawData = GetData(); string data = Encoding.UTF8.GetString(rawData); Assert.AreEqual("Constant", data, false, CultureInfo.InvariantCulture); While debugging this test, the data string appears to the naked eye to contain exactly the same string as the literal. When I called data.ToCharArray(), I noticed that the first byte of the string data is the value 65279 which is the UTF-8 Byte Order Marker. What I don't understand is why Encoding.UTF8.GetString() keeps this byte around. How do I get Encoding.UTF8.GetString() to not put the Byte Order Marker in the resulting string?
