• "An access violation (Segmentation Fault) raised in your program."

  - by Mark

  My C++ program compiles and works up until I call this function from main(): int uword(){fstream infile("numbers.txt"); fstream exfile("wordlist.txt"); string numb[numoflines]; string lines[numoflines]; number = 1; line = 1; for(int i=0;!infile.eof();++i) { getline (infile,number); numb[i] = number; getline (exfile,line); lines[i] = line; } infile.close(); exfile.close(); string yourword; Something here causes it to crash, in the debug it pops up with "An access violation (Segmentation Fault) raised in your program."

• Sometimes my dropdowns/datepickers will stop functioning?

  - by BlargINC

  Q: Where should I check to track this down? Issue: Opening a view model in my application sometimes makes dropdowns/datepickers nonfunctional. ie. dropdown won't drop and the datepicker calendar won't come up I suspect a binding issue but don't see one. Dropdowns have normal things like strings, numbers. One drop has a list of mini views. Datepickers are bound to nullable dates set in the constructor of the viewmodel. Note: These same things work in other viewmodels/views. I can paste code, I'm just not sure what code is relevant here.

  - by user187580

  Hello I have some data in the format of C222 = 50 C1234P687 = 'some text' C123YYY = 'text' C444 = 89 C345 = 3 C122P687 = 'some text' C122YYY = 'text' .... .... so basically 3 different forms "C" number = value, example - C444 = 89 "C" number "P" number = value, example - C123P687 = 'some text' "C" number "YYY" = value Only number is of variable length on the left side of (=) sign. Values vary. I want to store the data in db as INSERT INTO datatable c_id = "number after C" p_id = "number after P" // if it exists for a line of data value = 'value' yyy = 'value' Any ideas how to retrieve these numbers? Thanks

• How do I filter or retain duplicates in Perl?

  - by manu

  I have one text string which is having some duplicate characters (FFGGHHJKL). These can be made unique by using the positive lookahead: $ perl -pe 's/(.)(?=.*?\1)//g'] For example, with "FFEEDDCCGG", the output is "FEDCG". My question is how to make it work on the numbers (Ex. 212 212 43 43 5689 6689 5689 71 81 === output should be 212 43 5689 6689 71 81) ? Also if we want to have only duplicate records to be given as the output from a file having n rows 212 212 43 43 5689 6689 5689 71 81 66 66 67 68 69 69 69 71 71 52 .. Output: 212 212 43 43 5689 5689 66 66 69 69 69 71 71 How can I do this?

• Exception for java Swing application?

  - by Rich Fluckiger

  For some reason this is locking up the java application. Did I handle the exception correctly? private void submitButtonActionPerformed(java.awt.event.ActionEvent evt) { double amount, interest,rateCalc, a, b, c, payment; int years, months; while (true){ try{ amount = Double.valueOf(loanAmount.getText()); interest = Double.valueOf(interestRate.getText()); years = Integer.valueOf(loanYears.getText()); rateCalc = (interest/12); months = (years*12); a = Math.pow((1+rateCalc),months); b = (a*rateCalc); c = (a-1); payment = (amount *(b/c)); monthlyPayment.setText("Mortgage Payment $ = " + payment); } catch (NumberFormatException nfe){ javax.swing.JOptionPane.showMessageDialog(null, "Please enter numbers and not letters"); return; } } } monthlyPayment returns to the java app.

• Will Sytem.currentTimeMillis always return a value >= previous calls?

  - by 1984isnotamanual

  http://java.sun.com/j2se/1.4.2/docs/api/java/lang/System.html#currentTimeMillis() says: Returns the current time in milliseconds. Note that while the unit of time of the return value is a millisecond, the granularity of the value depends on the underlying operating system and may be larger. For example, many operating systems measure time in units of tens of milliseconds. It is not clear to me if I am guaranteed that this code will always print ever increasing (or the same) numbers. while (1) { System.out.println(System.currentTimeMillis() ); }

• Remove the period and everything after it using jQuery

  - by veryserious

  Is there a way to remove the period and everything after it using jQuery? The numbers following the period vary in length, so it's not as simple as finding the length. For example: <span class="changethis">505.234</span> <span class="changethis">23.93</span> Thanks for your help! P.S. (bonus) If there is a way to round up if it's x.5 or higher that would be awesome. Not essential though.

• Finding a integer number after a beginning t=

  - by user2966696

  I have a string like this: 33 00 4b 46 ff ff 03 10 30 t=25562 I am only interested in the five digits at the very end after the t= How can I get this numbers with a regular expression out of it? I tried grep t=..... but I also got all characters including the t= in the beginning, which I would like to drop? After finding that five digit number, I would like to divide this by 1000. So in the above mentioned case the number 25.562. Is this possible with grep and regular expressions? Thanks for your help.

• Dividing n-bit binary integers

  - by Julian

  Was wondering if anyone could help me with creating a pseudocode for how to go about dividing n-bit binary integers. Here is what I'm thinking could possibly work right now, could someone correct this if I'm wrong: divide (x,y) if x=0: return (0,0) //(quotient, remainder) (q,r) = divide(floor(x/2), y) q=2q, r=2r if x is odd: r = r+1 if r >= y: r = r-y, q = q+1 return (q,r) Would you guys say that this general pseudocode algorithm would accomplish the intended task of dividing n-bit numbers or am I missing something in my psuedocode before I start coding up something that's wrong?

• Can the Browser 'Forward' Button be Set from HTML?

  - by John C

  Example: At the bottom of the StackOver Questions page are a bunch of page numbers (1,2,3...), enclosed in a set of prev and next buttons. Clicking next repeatedly will bring me to, say page 5, at which point I will have: The page's prev button will be set to 'http://stackoverflow.com/questions?page=4' The Back button on my Browser will have the same value. The page's next button will be set to 'http://stackoverflow.com/questions?page=6' The Forward button on my Browser - won't be set to anything. Obviously, if I hit the Back button on the Browser, then Forward will have a value, pointing to the URL for page 5 - but not otherwise. Is there any way, from HTML (plus Javascript), to set the value of the Browser's Forward button? Or is this one of those things that HTML is simply forbidden to do?

• Limited recursion in C?

  - by function

  I ran this program and it output ... 65088 65089 65090 and then it stopped. Windows 7 said a.exe stopped working. Here is the code: #include <stdio.h> void go(void); main() { go(); } void go(void) { static int i = 0; printf("%d\n", i++); go(); } I think this program should keep on printing numbers indefinitely due to recursion, but it stops at 65090! The C code is compiled with gcc. Any ideas?

• PHP: Remove all fcn not acting as expected, Code Inside

  - by Josh K

  I made this simple function (remove all $elem from $array): function remall($array, $elem) { for($i=0; $i < count($array); $i++) if($array[$i] == $elem) unset($array[$i]); $newarray = array_values($array); return $newarray; } But it isn't working perfectly, here are some inputs and outputs $u = array(1, 7, 2, 7, 3, 7, 4, 7, 5, 7, 6, 7); $r = remall($u, 7); Output of $r: 12345767 $n = array(7, 7, 1, 7, 3, 4, 6, 7, 2, 3, 1, -3, 10, 11, 7, 7, 7, 2, 7); $r = remall($n, 7); Output of $r: 1346231-30117727 Notice how there are still 7s in my outputs. Also, My function will only be removing numbers from an array. Let me know if you spot something, thanks.

• Some pro regular expressions help needed here

  - by Camran

  I need a special regular expression, have no experience in them whatsoever so I am turning to you guys on this one: I need to validate a classifieds title field so it doesn't have any special characters in it, almost. Only letters and numbers should be allowed, and also the swedish three letters å, ä, ö, and also not case sensitive. Besides the above, these should also be allowed: The "&" sign. Parenthesis sign "()" Mathematical signs "-", "+", "%", "/", "*" Dollar and Euro signs Accent sign or whatever it's called, for example in "coupé" the apostrophe above the "e". Double quote and singel quote signs. The comma "," and point "." signs Thanks

• discrepancy in google analytics pageview totals when tracking subdomains

  - by frabjousB

  We are using the old urchin.js and are tracking 2 subdomains under the same profile. We have a “track subdomains” advanced filter defined (as per http://www.google.com/support/googleanalytics/bin/answer.py?hl=en&answer=55524) as well as 2 segments for presenting data in the reports: hostname matches exactly subdomain1.domain-name.com and hostname matches exactly subdomain2.domain-name.com When I apply these segments to our Top Content Overview report, the All Visits total for PageViews does not correspond to the # of visits reported for each subdomain. For example: All Visits = 53 subdomain1 = 24 subdomain2 = 32 Is there any reason as to why we would be seeing this discrepancy in numbers?

• C# massive insertion into data structures

  - by Seabass

  In C#, you can do the following: List registers = new List { 1, 2, 3, 4 }; This will produce a list with 1, 2, 3, and 4 in the list. Suppose that I am given a list from some function and I want to insert a bunch of numbers like the following: List register = somewhere(); register.Add(1); register.Add(2); register.Add(3); register.Add(4); Is there a cleaner way of doing this like the snippet above?

• Create ordering in a MySQL table without using a number (because then it's hard to put something in

  - by user347256

  I have a long list of items (say, a few million items) in a mysql table, let's call it mytable and it has the field mytable.itemid. The items are given an order, and can be re=ordered by the user by drag and drop. If I add a field called mytable.order and just put numbers in them, it creates problems: what if I want to move an item between 2 other items? Then all the order fields have to be updated? That seems like a nightmare. Is there a (scalable) way to add order to a table that is different from just giving every item a number, order by that, and do loads of SQL queries everytime the order is changed?

• Finding Most Recent Order for a Particular Item

  - by visitor

  I'm trying to write a SQL Query for DB2 Version 8 which retrieves the most recent order of a specific part for a list of users. The query receives a parameter which contains a list of customerId numbers and the partId number. For example, Order Table OrderID PartID CustomerID OrderTime I initially wanted to try: Select * from Order where OrderId = ( Select orderId from Order where partId = #requestedPartId# and customerId = #customerId# Order by orderTime desc fetch first 1 rows only ); The problem with the above query is that it only works for a single user and my query needs to include multiple users. Does anyone have a suggestion about how I could expand the above query to work for multiple users? If I remove my "fetch first 1 rows only," then it will return all rows instead of the most recent. I also tried using Max(OrderTime), but I couldn't find a way to return the OrderId from the sub-select. Thanks! Note: DB2 Version 8 does not support the SQL "TOP" function.

• Replacing characters in Ruby string according to some rule

  - by Kyle Kaitan

  In Ruby, I have a string of identical characters -- let's say they're all exclamation points, as in !!!!. I would like to replace the characters at certain indices with '*' if the integer corresponding to that index meets some criteria. For example, let's say I want to replace all the characters whose indices are even numbers and are greater than 3. In the string !!!!!!!! (8 characters long), that results in !!!!*!*! (indices 4 and 6 have been replaced). What's the most compact way to do this?

• Optimizing Solr for Sorting

  - by devinfoley

  I'm using Solr for a realtime search index. My dataset is about 60M large documents. Instead of sorting by relevance, I need to sort by time. Currently I'm using the sort flag in the query to sort by time. This works fine for specific searches, but when searches return large numbers of results, Solr has to take all of the resulting documents and sort them by time before returning. This is slow, and there has to be a better way. What is the better way?

• How to set AssemblyInfo.cs based on the tfs project build number?

  - by Ahok Rudraraju

  The project is hosted on a tfs server and I need to access the build number which I assume is automatically generated when ever you build a project. I need to retrieve that build number and display it on the web pages so that QAs and testing people know exactly which build they are working on. I found how to create customize build numbers in the following link: http://msdn.microsoft.com/en-us/library/aa395241(v=vs.100).aspx but it dose not solve my problem as I do not have access to the build definition file. I am looking for some kind of post deployment task which can access the build number or may be generate one and probably write it down to a file, from where I can read it. I don't know if that makes any sense as this is my first time working on .Net
