• Works on debug but not release

  - by user146780

  I have a thread that sets a value to true when it is done. Until then I wait: while(1) { if(done[0] == true) { break; } } This code works just fine in Debug but in Release it stays in the loop forever even though the debugger clearly says that it is true and not false. Why would this not work? Thanks

• Perl, foreach order

  - by Mike

  Does Perl's foreach loop operator require that the list items be presented in order? For example my @a=(1,2,3); foreach my $item (@a) { print $item; } will always print 1 2 3? I suspect so, but I can't find it documented.

• Auto Re-Running of Tests that fail

  - by Tangopop

  I have a set of Selenium/MbUnit Tests that work fine, but tend to take a while to run (over 4 hours) A problem i am finding is that about 1 in 20 test seems to timeout when running. I have confirmed the Selenium GRID is working and the Selenium RC's are all fine, it just seems to be a qwerk of the system. What is really annoying though is that if i run these tests again they will usually pass. What i want to know is if there is a way for me to auto rerun the tests (probably in the code) if a perticular type of exception is caught... I have attempted to put a few lines of code in the catch statement but i know this is a very hacky way of re running the tests. Here is the code: catch (AssertionException e) { if (e.Message() == "TimeOut") //Something similar to this { this.Test(); } else { verificationErrors.AppendLine(browserList[i] + " :: " + e.Message); } } Any suggestions?

• Is there a way to customise messages produced by statements in MS SQL Query Analyzer?

  - by Scott Leis

  If I run a simple query in SQL Query Analyzer, like: SELECT * FROM TableName the Messages pane always produces a message like: (30 row(s) affected) If I run a stored procedure with many statements, the messages are useless because there's no indication of what each one relates to. So firstly: Is there a way to customise the default messages on a per-query basis? E.g. I'd like a specific query to produce a message like: TableName query produced [numRowsAffected] results. replacing [numRowsAffected] with the number that would have appeared in the default message. Secondly, is there a way to suppress the default messages on a per-query basis? E.g. I have a local variable of type TABLE, used in several statements. I don't want any message to appear for statements where I'm just deleting data from that variable before re-using it. I'm seeking solutions that work in SQL Server 8.0.

• fill an array with Int like a Char; C++, cin object

  - by Duknov007

  This is a pretty simple question; first time poster and long time looker. Here is my binary to decimal converter I wrote: #include <iostream> #include <cmath> using namespace std; const int MAX = 6; int conv(int z[MAX], int l[6], int MAX); int main() { int zelda[MAX]; const int d = 6; int link[d]; cout << "Enter a binary number: \n"; int i = 0; while (i < MAX && (cin >> zelda[i]).get()) //input loop { ++i; } cout << conv(zelda, link, MAX); cin.get(); return 0; } int conv(int zelda[MAX], int link[6], int MAX) { int sum = 0; for (int t = 0; t < MAX; t++) { long int h, i; for (int h = 5, i = 0; h >= 0; --h, ++i) if (zelda[t] == 1) link[h] = pow(2.0, i); else link[h] = 0; sum += link[t]; } return sum; } With the way the input loop is being handled, I have to press enter after each input of a number. I haven't added any error correction yet either (and some of my variables are vague), but would like to enter a binary say 111111 instead of 1 enter, 1 enter, 1 enter, etc to fill the array. I am open to any technique and other suggestions. Maybe input it as a string and convert it to an int? I will keep researching. Thanks.

• Print numbers sequentially using printf with filling zeroes

  - by Werner

  Hi, in C++, using printf I want to print a sequence of number, so I get, from a "for" loop; 1 2 ... 9 10 11 and I create files from those numbers. But when I list them using "ls" I get 10 11 1 2 .. so instead of trying to solve the problem using bash, I wonder how could I print; 0001 0002 ... 0009 0010 0011 and so on Thanks

• Github + keep file but dont track changes

  - by Mike

  I have a codeigniter framework thats using github. Within this application I have several files that i will want to have in the repo but not track any changes on.. Example is: i deploy a new installation of this framework to a new client, i want the following files to be downloaded (they have default values 'CHANGEME') and i just have to make changes specific to this client IE(database credentials, email address info, custom css styling). // the production config files i want the files but they need to be updated to specific client needs application/config/production/config.php application/config/production/database.php application/config/production/tank_auth.php // index page, defines the environment (production|development) /index.php // all of the css/js cache (keep the folder but not the contents) /assets/cache/* // production user based styling (color, fonts etc) needs to be updated specific to client needs /assets/frontend/css/user/frontend-user.css currently if i run git clone [email protected]:user123/myRepo.git httpdocs and then i edit the files above, all is great.. until i release a hotfix or patch and run git pull. All of my changes are then overwritten.

• JAR file folder for eclipse projects

  - by Daff

  I'm trying to create a centralized folder (in some kind of a "meta project" in my eclipse workspace) for commonly used JAR files for referenced projects in this workspace. It should work similar to the WEB-INF/lib folder for web projects but also apply to non web projects, and automatically scan and add all jar files in this folder. I tried to create a user library with these jar files and reference them in the project but I still have to add every new jar manually to the user library (and don't know if it is referenced relative of absoulute) and Tomcat (WTP) doesn't seem to take these files (Run As - Run on Server) into its classpath (and I don't want to duplicate the jars and put them into WEB-INF/lib). Any ideas?

• LINQ to SQL .Count takes way to much process time and decreases performances.

  - by soldieraman

  LINQ to SQL .Count takes way to much process time and decreases performances. I am doing a recursive loop and for one child (lets call it parent) I have to check the number of children under it to make a decision if it should be included or not. The Count is too slow 8 ms :( for 120 parent records. Any ideas to make it quicker.

• how to get rows created with DataTable.NewRow() in C# / ADO.NET 2.0?

  - by matti

  Now I use Select and use a criteria which select only new rows. But is there any kind of GetInsertedRows-method. If I remember correctly there is status for each row so naturally one can loop through them all but that's not elegant. -Cheers -Matti

• Linux signals with extra information parameter

  - by Tester

  I was to have some extra information in the callback to sa_sigaction handler, it does not seems possible. So I was wondering if you could suggest me alternatives. Basic requirements: Function A raises an signal/event with a pointer to a struct Handler function tackles the event. The handler function would only be called on an event and a loop to wait for the event, as in select() , is undesirable. TIA

• Controlling rsync with Python?

  - by Cheesemold

  I've been wanting to write a python script that would run several instances of rsync in sequence for backing up data to a different computer. At the moment I just have this text file with the commands I use and I've just been copy-pasting them into the terminal, and it seems kinda silly. I want to be able to use python to do this for me. I know very vaguely how to use subprocess.popen, but I have no clue how to get python to interact with rsync directly, like for entering my password for me. Can python do that? Something like: if theProccess.proccessResponse == "Password:" : theProccess.respond(string) Or is the best that I can do is just have it, or even a bash script, just run the rsyncs in sequence and have to type my password in over and over again? Thanks in advance.

• Detect session hang and kill it

  - by Jack Juiceson

  Hi all, I have an asp.net page that runs certain algorithm and returns it's output. I was wondering what will happen and how to handle a case where the algorithm due to a bug goes into infinite loop. It will hog the cpu and other sessions will be served very slowly. I would love to have a way to tell IIS, if processing Algo.aspx takes more than 5 seconds, kill it or something like that. Thanks in advance

• Can I stop SQL*Plus from displaying "connected" when I have a "connect" in a script?

  - by René Nyffenegger

  I have a few sql scripts that I need to run via SQL*Plus. These scripts connect several times as different users with a connect user_01/pass_01@db_01. Now, each time the script does such a connect, it confirms the successful connection with a connected. This is distracting and I want to turn it off. I can achieve what I want with a set termout off connect user_01/pass_01@db_01 set termout on Is there a more elegant solution to my problem? Note, it doesn't help to permanently set termout off at the start of the script since I need to know if a command didn't run successfully.

• reading partially from sockets

  - by nomad.alien

  I'm having a little test program that sends a lot of udp packets between client-server-client (ping/pong test). The packets are fixed size on each run(last run is max allowable size of udp packet) I'm filling the packets with random data except for the beginning of each packet that contains the packet number. So I'm only interested to see if I receive all the packets back at the client. I'm using sendto() and recvfrom() and I only read the sizeof(packet_number) (which in this case is an int). What happens to the rest of the data? Does it end up in fairyland (gets discarded)? or does the new packet that arrives gets appended to this "old" data? (using linux)

• Chrome not displaying a div

  - by Kyle Sevenoaks

  Click here to see a simple example of what I want. It's really easy, but for some reason Google won't display the "subTotalCaption2" div. It's part of a foreach loop, if needed I can add other codes. There is nothing else in the rest of the css to mess with this, I have checked about 10 times. See it live at euroworker.no/order (add items to basket) In FF and Chrome. Thanks.

• RSpec leaves record in test database

  - by DMiller

  Whenever I run a user test, RSpec leaves the Fabricated user in the test database after the test has completed, which is messing up my other tests. I will do a rake db:test:prepare, but when I run my tests again, the record is recreated in my database. I have no idea why this is happening. It only happens with user objects. In my spec_helper file I even have: config.use_transactional_fixtures = true Here is an example test that creates a record: it "creates a password reset token for the user" do alice = Fabricate(:user) post :create, email: alice.email expect(assigns(alice.password_reset_token)).to_not eq(nil) end Fabricator: Fabricator(:user) do email { Faker::Internet.email } password 'password' name { Faker::Name.name } end Could this have anything to do with my users model?

• Objective C "do - while" question

  - by Rob

  The example for one of the exercises in the book I am reading shows the following code: #import <Foundation/Foundation.h> int main (int argc, const char * argv[]) { NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init]; int input, reverse, numberOfDigits; reverse = 0; numberOfDigits = 0; NSLog (@"Please input a multi-digit number:"); scanf ("%i", &input); if ( input < 0 ) { input = -input; NSLog (@"Minus"); } do { reverse = reverse * 10 + input % 10; numberOfDigits++; } while (input /= 10); do { switch ( reverse % 10 ) { case 0: NSLog (@"Zero"); break; case 1: NSLog (@"One"); break; case 2: NSLog (@"Two"); break; case 3: NSLog (@"Three"); break; case 4: NSLog (@"Four"); break; case 5: NSLog (@"Five"); break; case 6: NSLog (@"Six"); break; case 7: NSLog (@"Seven"); break; case 8: NSLog (@"Eight"); break; case 9: NSLog (@"Nine"); break; } numberOfDigits--; } while (reverse /= 10); while (numberOfDigits--) { NSLog (@"Zero"); } [pool drain]; return 0; } My question is this, the while statement shows (input /= 10) which, if I understand this correctly basically means (input = input / 10). Now, if that is true, why doesn't the loop just run continuously? I mean, even if you were to divide 0 by 10 then that would still extract a number. If the user was to input "50607", it would first cut off the "7", then the "0", and so on and so on, but why does it exit the loop after removing the "5". Wouldn't the response after the "5" be the same as the "0" between the 5 and the 6 to the program?
