  • Regex to Strip Special Characters

    - by Neil
    I am trying to use regex.replace to strip out unwanted characters, but I need to account for spaces: string asdf = "doésn't work?"; string regie = @"([{}\(\)\^$&._%#!@=<>:;,~`'\’ \*\?\/\+\|\[\\\\]|\]|\-)"; Response.Write(Regex.Replace(asdf,regie,"").Replace(" ","-")); returns doésntwork instead of doésnt-work Ideas? Thanks!

  • Eclipse IDE's Hello World Cheatsheet seems to have a mistake

    - by Sean
    Hey guys, Just a warning: I'm completely new to Java and am trying to teach myself Android programming. I installed the Eclipse IDE today and tried to walk through the first Java Hello World "cheat sheet," and it didn't work! I was really quite surprised. When it asked me to select the checkbox to create the main() method, there wasn't anything on-screen that looked like a checkbox with "main()" or "method" next to it, so I guessed that maybe what they meant was the "Modifiers" radio button. So I left that checked for "public." It didn't compile and I got red X's next to every folder in my Package Explorer. Has anybody else had this problem? Thanks!

  • Authentication problem with Wufoo

    - by fudgey
    I set up a Wufoo form with admin only portions that will only show up if I am logged in. I read through the Wufoo API documentation and I can get the authenication to work, but when I try to access the form after I authenticate, it says I need to authenticate. This is what I have so far (subdomain, api key & form id changed) <?php error_reporting(E_ALL); ini_set('display_errors', 1); $curl1 = curl_init('http://fishbowl.wufoo.com/api/v3/users.xml'); curl_setopt($curl1, CURLOPT_RETURNTRANSFER, 1); curl_setopt($curl1, CURLOPT_USERPWD, 'AOI6-LFKL-VM1Q-IEX9:footastic'); curl_setopt($curl1, CURLOPT_HTTPAUTH, CURLAUTH_ANY); curl_setopt($curl1, CURLOPT_SSL_VERIFYPEER, false); curl_setopt($curl1, CURLOPT_FOLLOWLOCATION, false); curl_setopt($curl1, CURLOPT_USERAGENT, 'Wufoo Sample Code'); $response = curl_exec($curl1); $resultStatus = curl_getinfo($curl1); if($resultStatus['http_code'] == 200) { echo 'success!<br>'; } else { echo 'Call Failed '.print_r($resultStatus); } $curl2 = curl_init("http://fishbowl.wufoo.com/api/v3/forms/w7x1p5/entries.json"); curl_setopt($curl2, CURLOPT_HEADER, 0); curl_setopt($curl2, CURLOPT_RETURNTRANSFER, 1); $response = curl_exec($curl2); curl_close ($curl2); echo $response; curl_close($curl1); ?> It doesn't matter if I close $curl1 before or after I call $curl2, I get the same message on my screen: success! You must authenticate to get at the goodies. and I know the api, subdomain and form id are all correct. And one last bonus question... can I do all of this using Ajax instead? - the page I will be displaying the form on will already be limited to admin access, so exposing the API shouldn't matter.

  • Why is my simple recusive method for this game always off by 1?

    - by FrankTheTank
    I'm attempting to create a text-based version of this game: http://www.cse.nd.edu/java/SameGame.html Here is the code I have so far: #include <iostream> #include <vector> #include <ctime> class Clickomania { public: Clickomania(); std::vector<std::vector<int> > board; int move(int, int); bool isSolved(); void print(); void pushDown(); bool isValid(); }; Clickomania::Clickomania() : board(12, std::vector<int>(8,0)) { srand((unsigned)time(0)); for(int i = 0; i < 12; i++) { for(int j = 0; j < 8; j++) { int color = (rand() % 3) + 1; board[i][j] = color; } } } void Clickomania::pushDown() { for(int i = 0; i < 8; i++) { for(int j = 0; j < 12; j++) { if (board[j][i] == 0) { for(int k = j; k > 0; k--) { board[k][i] = board[k-1][i]; } board[0][i] = 0; } } } } int Clickomania::move(int row, int col) { bool match = false; int totalMatches = 0; if (row > 12 || row < 0 || col > 8 || col < 0) { return 0; } int currentColor = board[row][col]; board[row][col] = 0; if ((row + 1) < 12) { if (board[row+1][col] == currentColor) { match = true; totalMatches++; totalMatches += move(row+1, col); } } if ((row - 1) >= 0) { if (board[row-1][col] == currentColor) { match = true; totalMatches++; totalMatches += move(row-1, col); } } if ((col + 1) < 8) { if (board[row][col+1] == currentColor) { match = true; totalMatches++; totalMatches += move(row, col+1); } } if ((col - 1) >= 0) { if (board[row][col-1] == currentColor) { match = true; totalMatches++; totalMatches += move(row, col-1); } } return totalMatches; } void Clickomania::print() { for(int i = 0; i < 12; i++) { for(int j = 0; j < 8; j++) { std::cout << board[i][j]; } std::cout << "\n"; } } int main() { Clickomania game; game.print(); int row; int col; std::cout << "Enter row: "; std::cin >> row; std::cout << "Enter col: "; std::cin >> col; int numDestroyed = game.move(row,col); game.print(); std::cout << "Destroyed: " << numDestroyed << "\n"; } The method that is giving me trouble is my "move" method. This method, given a pair of coordinates, should delete all the squares at that coordinate with the same number and likewise with all the squares with the same number connected to it. If you play the link I gave above you'll see how the deletion works on a click. int Clickomania::move(int row, int col) { bool match = false; int totalMatches = 0; if (row > 12 || row < 0 || col > 8 || col < 0) { return 0; } int currentColor = board[row][col]; board[row][col] = 0; if ((row + 1) < 12) { if (board[row+1][col] == currentColor) { match = true; totalMatches++; totalMatches += move(row+1, col); } } if ((row - 1) >= 0) { if (board[row-1][col] == currentColor) { match = true; totalMatches++; totalMatches += move(row-1, col); } } if ((col + 1) < 8) { if (board[row][col+1] == currentColor) { match = true; totalMatches++; totalMatches += move(row, col+1); } } if ((col - 1) >= 0) { if (board[row][col-1] == currentColor) { match = true; totalMatches++; totalMatches += move(row, col-1); } } return totalMatches; } My move() method above works fine, as in, it will delete the appropriate "blocks" and replace them with zeros. However, the number of destroyed (value returned) is always one off (too small). I believe this is because the first call of move() isn't being counted but I don't know how to differentiate between the first call or subsequent calls in that recursive method. How can I modify my move() method so it returns the correct number of destroyed blocks?

  • Boolean 'NOT' in T-SQL not working on 'bit' datatype?

    - by Joannes Vermorel
    Trying to perform a single boolean NOT operation, it appears that under MS SQL Server 2005, the following block does not work DECLARE @MyBoolean bit; SET @MyBoolean = 0; SET @MyBoolean = NOT @MyBoolean; SELECT @MyBoolean; Instead, I am getting more successful with DECLARE @MyBoolean bit; SET @MyBoolean = 0; SET @MyBoolean = 1 - @MyBoolean; SELECT @MyBoolean; Yet, this looks a bit a twisted way to express something as simple as a negation. Am I missing something?

  • how to extract elements from a list in python ?

    - by Stefano Borini
    I feel suddenly uneasy of not being able to perform this operation easily. It could be that I'm tired, or that there's really no way (google didn't help), but... if you have a list in python, and want to extract element at indices say 1, 2 and 5 into a new list, how do you do ? This is how I did it, but I'm not very satisfied >>> a [10, 11, 12, 13, 14, 15] >>> [x[1] for x in enumerate(a) if x[0] in [1,2,5]] [11, 12, 15] any better way ? more in general, given a tuple with indices, how to use this tuple to extract the corresponding elements from a list, eventually with duplication (e.g. tuple (1,1,2,1,5) produces [11,11,12,11,15] )

  • Optimizing if-else /switch-case with string options

    - by cc
    What modification would bring to this piece of code? In the last lines, should I use more if-else structures, instead of "if-if-if" if (action.equals("opt1")) { //something } else { if (action.equals("opt2")) { //something } else { if ((action.equals("opt3")) || (action.equals("opt4"))) { //something } if (action.equals("opt5")) { //something } if (action.equals("opt6")) { //something } } } Later Edit: This is Java. I don't think that switch-case structure will work with Strings. Later Edit 2: A switch works with the byte, short, char, and int primitive data types. It also works with enumerated types (discussed in Classes and Inheritance) and a few special classes that "wrap" certain primitive types: Character, Byte, Short, and Integer (discussed in Simple Data Objects ).

  • Place the business logic in Java Beans?

    - by Lirik
    I was reading this page and I found the following statement: MVC in Java Server Pages Now that we have a convenient architucture to separate the view, how can we leverage that? Java Server Pages (JSP) becomes more interesting because the HTML content can be separated from the Java business objects. JSP can also make use of Java Beans. The business logic could be placed inside Java Beans. If the design is architected correctly, a Web Designer could work with HTML on the JSP site without interfering with the Java developer. Interestingly in my textbook I pulled the following quote: In the MVC architecture... the original request is always handled by a servlet. The servlet invokes the business logic and data access code and creates beans to represent the results (that’s the model). Then, the servlet decides which Java Server Page is appropriate to present those particular results and forwards the request there (the JSP is the view). The servlet decides what business logic code applies and which JSP should present the results (the servlet is the controller). The two statements seem slightly contradicting. What is the best way to use beans: should we place business logic in them or should we only place results in them? Are there ways in which beans are inadequate for representing a model?

  • Throw of a die in Java

    The throw of a die is a popular program in Java, public class Die { /* This program simulates rolling a die */ public static void main(String[] args) { int die; // The number on the die. die = (int)(Math.random()*6 + 1); System.out.println (die); } // end main() } // end class What I wish to do is make it repeat, 500 times. I have not been able to put this program into a loop of 500. I usually program in Python, thus I guess my Java has rusted ! Any help is most welcome !

  • Using EclipseLink

    - by Ross Peoples
    I am still new to Java and Eclipse and I'm trying to get my application to connect to a database. I think I want to use EclipseLink, but all of the documentation on the matter assumes you already know everything there is to know about everything. I keep getting linked back to this tutorial: http://www.vogella.de/articles/JavaPersistenceAPI/article.html But it's basically useless because it doesn't tell you HOW to do anything. For the Installation section, it tells you to download EclipseLink and gives you a link to the download page, but doesn't tell you what to do with it after you download. The download page doesn't either. I used the "Install new software" option in Eclipse to install EclipseLink into Eclipse, but it gave me like 4 different options, none of which are explained anywhere. It gave me options JPA, MOXy, SDO, etc, but I don't know which one I need. I just installed them all. Everything on the web assumes you are already a Java guru and things that are second nature to Java devs are never explained, so it's very frustrating for someone trying to learn. So how do I install and USE EclipseLink in my project and what do I need to do to connect it to a Microsoft SQL server? Again, I am new to all of this so I have no clue what to do. Thanks for the help.

  • Python unit-testing with nose: Making sequential tests

    - by cool-RR
    I am just learning how to do unit-testing. I'm on Python / nose / Wing IDE. (The project that I'm writing tests for is a simulations framework, and among other things it lets you run simulations both synchronously and asynchronously, and the results of the simulation should be the same in both.) The thing is, I want some of my tests to use simulation results that were created in other tests. For example, synchronous_test calculates a certain simulation in synchronous mode, but then I want to calculate it in asynchronous mode, and check that the results came out the same. How do I structure this? Do I put them all in one test function, or make a separate asynchronous_test? Do I pass these objects from one test function to another? Also, keep in mind that all these tests will run through a test generator, so I can do the tests for each of the simulation packages included with my program.

  • Running an allocation simulation repeatedly breaks after the first run.

    - by Az
    Background I have a bunch of students, their desired projects and the supervisors for the respective projects. I'm running a battery of simulations to see which projects the students end up with, which will allow me to get some useful statistics required for feedback. So, this is essentially a Monte-Carlo simulation where I'm randomising the list of students and then iterating through it, allocating projects until I hit the end of the list. Then the process is repeated again. Note that, within a single session, after each successful allocation of a project the following take place: + the project is set to allocated and cannot be given to another student + the supervisor has a fixed quota of students he can supervise. This is decremented by 1 + Once the quota hits 0, all the projects from that supervisor become blocked and this has the same effect as a project being allocated Code def resetData(): for student in students.itervalues(): student.allocated_project = None for supervisor in supervisors.itervalues(): supervisor.quota = 0 for project in projects.itervalues(): project.allocated = False project.blocked = False The role of resetData() is to "reset" certain bits of the data. For example, when a project is successfully allocated, project.allocated for that project is flipped to True. While that's useful for a single run, for the next run I need to be deallocated. Above I'm iterating through thee three dictionaries - one each for students, projects and supervisors - where the information is stored. The next bit is the "Monte-Carlo" simulation for the allocation algorithm. sesh_id = 1 for trial in range(50): for id in randomiseStudents(1): stud_id = id student = students[id] if not student.preferences: # Ignoring the students who've not entered any preferences for rank in ranks: temp_proj = random.choice(list(student.preferences[rank])) if not (temp_proj.allocated or temp_proj.blocked): alloc_proj = student.allocated_proj_ref = temp_proj.proj_id alloc_proj_rank = student.allocated_rank = rank successActions(temp_proj) temp_alloc = Allocated(sesh_id, stud_id, alloc_proj, alloc_proj_rank) print temp_alloc # Explained break sesh_id += 1 resetData() # Refer to def resetData() above All randomiseStudents(1) does is randomise the order of students. Allocated is a class defined as such: class Allocated(object): def __init__(self, sesh_id, stud_id, alloc_proj, alloc_proj_rank): self.sesh_id = sesh_id self.stud_id = stud_id self.alloc_proj = alloc_proj self.alloc_proj_rank = alloc_proj_rank def __repr__(self): return str(self) def __str__(self): return "%s - Student: %s (Project: %s - Rank: %s)" %(self.sesh_id, self.stud_id, self.alloc_proj, self.alloc_proj_rank) Output and problem Now if I run this I get an output such as this (truncated): 1 - Student: 7720 (Project: 1100241 - Rank: 1) 1 - Student: 7832 (Project: 1100339 - Rank: 1) 1 - Student: 7743 (Project: 1100359 - Rank: 1) 1 - Student: 7820 (Project: 1100261 - Rank: 2) 1 - Student: 7829 (Project: 1100270 - Rank: 1) . . . 1 - Student: 7822 (Project: 1100280 - Rank: 1) 1 - Student: 7792 (Project: 1100141 - Rank: 7) 2 - Student: 7739 (Project: 1100267 - Rank: 1) 3 - Student: 7806 (Project: 1100272 - Rank: 1) . . . 45 - Student: 7806 (Project: 1100272 - Rank: 1) 46 - Student: 7714 (Project: 1100317 - Rank: 1) 47 - Student: 7930 (Project: 1100343 - Rank: 1) 48 - Student: 7757 (Project: 1100358 - Rank: 1) 49 - Student: 7759 (Project: 1100269 - Rank: 1) 50 - Student: 7778 (Project: 1100301 - Rank: 1) Basically, it works perfectly for the first run, but on subsequent runs leading upto the nth run, in this case 50, only a single student-project allocation pair is returned. Thus, the main issue I'm having trouble with is figuring out what is causing this anomalous behaviour especially since the first run works smoothly. Thanks in advance, Az

  • Convert string to decimal retaining the exact input format

    - by Brett
    Hi All, I'm sure this is a piece of cake but I'm really struggling with something that seems trivial. I need to check the inputted text of a textbox on the form submit and check to see if it's within a desired range (I've tried a Range Validator but it doesn't work for some reason so I'm trying to do this server-side). What I want to do is: Get the value inputted (eg. 0.02), replace the commas and periods, convert that to a decimal (or double or equivalent) and check to see if it's between 0.10 and 35000.00. Here's what I have so far: string s = txtTransactionValue.Text.Replace(",", string.Empty).Replace(".", string.Empty); decimal transactionValue = Decimal.Parse(s); if (transactionValue >= 0.10M && transactionValue <= 35000.00M) // do something If I pass 0.02 into the above, transactionValue is 2. I want to retain the value as 0.02 (ie. do no format changes to it - 100.00 is 100.00, 999.99 is 999.99) Any ideas? Thanks in advance, Brett

    I just downloaded Scrapy (web crawler) on Windows 32 and have just created a new project folder using the "scrapy-ctl.py startproject dmoz" command in dos. I then proceeded to created the first spider using the command: scrapy-ctl.py genspider myspider myspdier-domain.com but it did not work and returns the error: Error running: scrapy-ctl.py genspider, Cannot find project settings module in python path: scrapy_settings. I know I have the path set right (to python26/scripts), but I am having difficulty figuring out what the problem is. I am new to both scrapy and python so there is a good possibility that I have failled to do something important. Also, I have been using eclipse with the Pydev plugin to edit the code if that might cause some problems.

  • Using a handle to collect output from CreateProcess()

    - by Stef
    Hi I am using CreateProcess() to run an external console application in Windows from my GUI application. I would like to somehow gather the output to know whether there were errors. Now I know I have to do something with hStdOutput, but I fail to understand what. I am new to c++ and an inexperienced programmer and I actually don't know what to do with a handle or how to light a pipe. How do I get the output to some kind of variable (or file)? This is what I have a the moment: void email::run(string path,string cmd){ WCHAR * ppath=new(nothrow) WCHAR[path.length()*2]; memset(ppath,' ',path.length()*2); WCHAR * pcmd= new(nothrow) WCHAR[cmd.length()*2]; memset(pcmd,' ',cmd.length()*2); string tempstr; ToWCHAR(path,ppath); //creates WCHAR from my std::string ToWCHAR(cmd,pcmd); STARTUPINFO info={sizeof(info)}; info.dwFlags = STARTF_USESHOWWINDOW; //hide process PROCESS_INFORMATION processInfo; if (CreateProcess(ppath,pcmd, NULL, NULL, FALSE, 0, NULL, NULL, &info, &processInfo)) { ::WaitForSingleObject(processInfo.hProcess, INFINITE); CloseHandle(processInfo.hProcess); CloseHandle(processInfo.hThread); } delete[](ppath); delete[](pcmd); } This code probably makes any decent programmer scream, but (I shouldn't even say it:) It works ;-) The Question: How do I use hStdOutput to read the output to a file (for instance)?

  • Open Source Utilization Questions: How do you lone wold programmers best take advantage of open sour

    - by Funkyeah
    For Clarity: So you come up with an idea for a new program and want to start hacking, but you also happen to be a one-man army. How do you programming dynamos best find and utilize existing open-source software to give you the highest jumping off point possible when diving into your new project? When you do jump in where the shit do you start from? Any imaginary scenarios would be welcome, e.g. a shitty example might be utilizing a open-source database with an open-source IM client as a starting off point to a make a new client where you could tag and store conversations and query those tags at a later time.
