• Visual Studio swapping code between projects?!?!?!?!??!

  - by Tom

  Are there any known issues with visual studio and code being swapped between projects? I had a project running in VS2008 and when i went back to it, the code from another project had been swapped in the Program.cs class. I havent made any mistakes, im not talking about some code- i mean the whole project had been swapped out. Its as if the .proj files or .soln files had been swapped from their project folders??? EDIT Ive restarted laptop, opened the code again and its still showing the wrong code BUT when i execute it, its the right code?!?!?!

• Splitting up input using regular expressions in Java

  - by Joe24

  I am making a program that lets a user input a chemical for example C9H11N02. When they enter that I want to split it up into pieces so I can have it like C9, H11, N, 02. When I have it like this I want to make changes to it so I can make it C10H12N203 and then put it back together. This is what I have done so far. using the regular expression I have used I can extract the integer value, but how would I go about get C10, H11 etc..? System.out.println("Enter Data"); Scanner k = new Scanner( System.in ); String input = k.nextLine(); String reg = "\\s\\s\\s"; String [] data; data = input.split( reg ); int m = Integer.parseInt( data[0] ); int n = Integer.parseInt( data[1] );

• Small questions on data structure

  - by John Graveston

  Hi, I'm trying to search the parent of a node with Kruskal's algorithm. My program works just fine, but I think I have heard of a method to improve the speed of the algorithm by reconstructing the tree while searching for the parent node and connecting it to the parent node. I'm pretty sure that I've heard of this somewhere, maybe in a lecture. Can anyone refresh my memory? And also, given a number of arrays, when searching for the minimum and the maximum value from a certain section of an array, what is the name of the tree that can calculate the minimum/maximum value from the array by making a binary tree that has the minimum/maximum value of each array in O(log N)?

• Notepad++ regular expression find and replace $_REQUEST with $_GET but a more secure

  - by David

  What I am doing is replacing, in a large program, all $_REQUEST['var'] and mysql_escape_string($_REQUEST['var']) with either the 1st or 2nd line below the dotted line. Now, I have figured out this much of the regular expression but I would like to make it simpler. Instead of having to run the top one first then the 2nd one I would like to just run one all together. I tried this but it did not work. (mysql_escape_string\()*$_REQUEST\[\'([^']*)\'\]\)(\)*) So below is what works but again have to do it twice. $_REQUEST\[\'([^']*)\'\] mysql_escape_string\($_REQUEST\[\'([^']*)\'\]\) (isset($_GET['\1'])?mysql_real_escape_string($_GET['\1']):false) (isset($_POST['\1'])?mysql_real_escape_string($_POST['\1']):false) ============================ Update: Yeah, after some research I figured out that Notepad++ does not support most regular expressions. I guess one additional step can not hurt a person. It's just laziness. *NOTE: BUT if anyone wants to try feel free to comment. At least it is just 2 steps and not 20.

• undefined reference to "func" when complied with GCC

  - by hotlemontea

  I implement a link list in two files in linklist.h and linklist.c, and I call some functions defined in linklist.h in main function of main.c. linklist.h is included in both linklist.c and main.c. When I compile this program by GCC with Makefile, the error named "undefined reference to xxx" occurs. I think my Makefile is written correctly as below. So what is the possible reason for this linking error CC=gcc CFLAGS= -g -O2 TARGET=target OBJECTS=main.o linklist.o TARGET: $(OBJECTS) $(CC) $(CFLAGS) $(OBJECTS) -o $(TARGET) clean: rm target $(OBJECTS) main.o:linklist.h linklist.o:linklist.h

• Cross vertion line matching.

  - by BCS

  I'm considering how to do automatic bug tracking and as part of that I'm wondering what is available to match source code line numbers (or more accurate numbers mapped from instruction pointers via something like addr2line) in one version of a program to the same line in another. (Assume everything is in some kind of source control and is available to my code) The simplest approach would be to use a diff tool/lib on the files and do some math on the line number spans, however this has some limitations: It doesn't handle cross file motion. It might not play well with lines that get changed It doesn't look at the information available in the intermediate versions. It provides no way to manually patch up lines when the diff tool gets things wrong. It's kinda clunky Before I start diving into developing something better: What already exists to do this? What features do similar system have that I've not thought of?

• How can I modify the application file of an application that is currently running (on Linux)?

  - by Hach-Que

  I have an application running called AppFS. This application has an ext2 filesystem just attached to the end of the file (it's positioned so that the application binary exists in a 1MB spacing area, followed by the ext2 data). Now I've got FUSE embedded in the program and I've managed to extract the filesystem out of the application data into a temporary file so that FUSE can mount / use it. The problem I have now is writing the temporary file back into the application file. I get "Text file busy" presumably because the application has locked itself and won't let writes occur. Is there a way I can force the file to become unlocked so I can write data to it? (It's important to note that I'm not changing the application binary area - just rewriting the ext2 component.) It needs to be unlocked without requiring root permissions (unlocked by the same user who started the application).

• Need a field / flag / status number for mutliple use ?

  - by Jules

  I want to create a field in my database which will be easy to query. I think if I give a bit of background this will make more sense. My table has listings shown on my website. I run a program which looks at the listings a decides whether to hide them from being shown on the site. I also hide listings manually for various reasons. I want to store these reasons in a field, so more than one reason could be made for hiding. So I need some form of logic to determine which reasons have been used. Can anyone offer me any guidance on what will be future-proof aka new reasons and what will be quick and easy to query upon ?

• looping thru a list of checkboxes and saving the values, not working properly

  - by Erez

  Hello all, I'm having a bit of a problem with this code. The program gives me a list of checkboxes but a user ID. then u user can change his selection and push the save button (id="btnSaveUserIntersts") and i am trying to save in the hidden textbox all the values of the checkboxes that was choosen. The problem is that i am getting all the time the same selections that came form the database and not getting the new selection that the user made. Can any one tell me what am i doing wrong here? $(document).ready( function() { $('#btnSaveUserIntersts').bind( 'click', function() { var strCheckBoxChecked = new String(); $('input[type=checkbox][checked]').each( function() { strCheckBoxChecked += $(this).val(); strCheckBoxChecked += ','; } ); $('#hidUserInterests').val(strCheckBoxChecked); } ); } ); 10x

• Easy Threading in WPF

  - by Sandeep Bansal

  Hi everyone, I've been reading a lot about threading in C#, WPF and Silverlight but can't get it to work. My main problem is I have the _load (_Initialized) action and it has a lot of object creation and along with that I have timers working doing different things, this causes the startup time of the program to be very slow and obviously causes the UI to hang and it isn't a good thing for deploying to a lot of users. My timers change values of labels and textfields but having them do that on another thread is an obvious no go. So can someone give me some examples on how to achieve what I need to do? Thanks

• Bash redirection: save stderr/stdout to different files and still print them out on a console

  - by Alby

  Here is a simple program. class Redirection { public static void main (String args[]){ System.out.println("Hello World_Stdout"); System.err.println("Hello World_Stderr"); } } I want to see the all the outputs on a console, but at the same time I want to store stdout and stderr in different files. I tried the following command, to no avail. $java Redirection 3>&1 2>stderr 1>stdout 1>&3 2>&3 stderr& stdout files have the file size of 0. So basically I want to do what "tee" command does but I also want to capture stderr as well.

• Why can't my C# app create files in Windows 7?

  - by WindyCityEagle

  I have a C# app that creates a settings file for itself to store the current state of certain visual elements. This app works just fine on any machine that isn't running Windows 7, but on those machines we get an error that the settings file can't be created because the user doesn't have permission. Now, I could fix this issue by going to each computer, logging in as the administrator and giving the user read and write access on the program folder for the application that we've installed, but there has to be a better way. It seems like in XP, you got write access on the folders you created by default, but that isn't the case anymore. Is there a setting I need in the setup package to make this work?

• cygwin c sem_init

  - by RileyVanZeeland

  if((sem_init(sem, 1, 1)) == 1) perror("error initiating sem"); If I include this line of code my program simply starts and exits. I just started learning how to use semaphores. I'm using cygwin and when this line is commented out the printf's ABOVE this print to console but when include this, nothing happens. I did the following to get cygserver going- CYGWIN=server ran /bin/cygserver-config ran /usr/sbin/cygserver for the config it said the cygserver is already running And for the sygserver it saids- initailaizing complete failed to created named pipe: is the daemon already running? fatal error on IPC transport: closing down Any ideas?

• Using FILE_FLAG_NO_BUFFERING will return noticeable speed gain?

  - by 9dan

  Recently noticed detail description of FILE_FLAG_NO_BUFFERING flag in MSDN, and read several Google search results about unbuffered I/O in Windows. http://msdn.microsoft.com/en-us/library/aa363858(v=vs.85).aspx I wondering now, is it really important to consider unbuffered option in file I/O programming? Because many programs use plain old C stream I/O or C++ iostream, I didn't gave any attention to FILE_FLAG_NO_BUFFERING flag before. Let's say we are developing photo explorer program like Picasa. If we implement unbuffered I/O, could thumbnail display speed show noticeable difference in ordinary users?

• How do C++ header files work?

  - by PulpFiction

  Hi all. When I include some function from a header file in a C++ program, does the entire header file code get copied to the final executable or only the machine code for the specific function is generated. For example, if I call std::sort from the <algorithm> header in C++, is the machine code generated only for the sort() function or for the entire <algorithm> header file. I think that a similar question exists somewhere on Stack Overflow, but I have tried my best to find it (I glanced over it once, but lost the link). If you can point me to that, it would be wonderful.

• dealing with IO vs pure code in haskell

  - by Drakosha

  I'm writing a shell script (my 1st non-example in haskell) which is supposed to list a directory, get every file size, do some string manipulation (pure code) and then rename some files. I'm not sure what i'm doing wrong, so 2 questions: How should i arrange the code in such program? I have a specific issue, i get the following error, what am i doing wrong? error: Couldn't match expected type [FilePath]' against inferred typeIO [FilePath]' In the second argument of mapM', namelyfileNames' In a stmt of a 'do' expression: files <- (mapM getFileNameAndSize fileNames) In the expression: do { fileNames <- getDirectoryContents; files <- (mapM getFileNameAndSize fileNames); sortBy cmpFilesBySize files } code: getFileNameAndSize fname = do (fname, (withFile fname ReadMode hFileSize)) getFilesWithSizes = do fileNames <- getDirectoryContents files <- (mapM getFileNameAndSize fileNames) sortBy cmpFilesBySize files

• Allocate from buffer in C

  - by Grimless

  I am building a simple particle system and want to use a single array buffer of structs to manage my particles. That said, I can't find a C function that allows me to malloc() and free() from an arbitrary buffer. Here is some pseudocode to show my intent: Particle* particles = (Particle*) malloc( sizeof(Particle) * numParticles ); Particle* firstParticle = <buffer_alloc>( particles ); initialize_particle( firstParticle ); // ... Some more stuff if (firstParticle->life < 0) <buffer_free>( firstParticle ); // @ program's end free(particles); Where <buffer_alloc> and <buffer_free> are functions that allocate and free memory chunks from arbitrary pointers (possibly with additional metadata such as buffer length, etc.). Do such functions exist and/or is there a better way to do this? Thank you!

• C++ runtime, display exception message

  - by aaa

  hello. I am using gcc on linux to compile C++ code. There are some exceptions which should not be handled and should close program. However, I would like to be able to display exception string: For example: throw std::runtime_error(" message"); does not display message, only type of error. I would like to display messages as well. Is there way to do it? it is a library, I really do not want to put catch statements and let library user decide. However, right now library user is fortran, which does not allow to handle exceptions. in principle, I can put handlers in wrapper code, but rather not to if there is a way around Thanks

• Get the co-ordinates of a touch event on Android

  - by Joe

  Hi, I'm new to Android, I've followed the hello world tutorial through and have a basic idea of what's going on. I'm particularly interested in the touch screen of my T-Mobile Pulse so just to get me started I want to be able to write the co-ordinates of a tocuh event on the screen, so say the user touched the co-ordinate 5,2 - a textview on the screen would display that. At present I have a simple program that just loads an xml file which contains the textview I intend to write the co-ordinates in. Thank you in advance, I did Google for help and searched stackoverflow but everything I found either went way over my head or wasn't suitable for this. Cheers.

• Date range advanced count calculation in TSQL

  - by cihata87

  I am working on call center project and I have to calculate the call arrivals at the same time between specific time ranges. I have to write a procedure which has parameters StartTime, EndTime and Interval For Example: Start Time: 11:00 End Time: 12:00 Interval: 20 minutes so program should divide the 1-hour time range into 3 parts and each part should count the arrivals which started and finished in this range OR arrivals which started and haven't finished yet Should be like this: 11:00 - 11:20 15 calls at the same time(TimePeaks) 11:20 - 11:40 21 calls ... 11:40 - 12:00 8 calls ... Any suggestions how to calculate them?

• Finding data file location while using Microsoft Test Framework

  - by Nair

  I have been using NUnit and now I am switching to the Microsoft Unit Test frame work. In my test project I have a folder called TestData and I kept all my test input data files there. I want to use that files for my unit testing. In my test code, I am using Application name space and assembly name space but I can not get to the data folder directly until unless I write a code to find and replace some string to point to the data folder. I am sure someone might have run into the same problem, is the solution to change the path through program or is there a API call which will let us get to executing assembly folders? Thanks,

• How do you make long SQL invoked from other code readable?

  - by Artem

  This is a very open question, but I think it can be very beneficial for SQL readability. So you have a Java program, and you are trying to call a monster SQL statement from it, with many subqueries and joins. The starting point for my question is a string constant like this: static string MONSTER_STATEMENT = "SELECT " + " fields" + "WHERE "+ " fieldA = (SELECT a FROM TableC) " + "AND fieldB IN (%s)" + "AND fieldC = %d " + "FROM " " tableA INNER JOIN tableB ON ..."; It later gets filled using String.format and executed. What are you tricks for making this kind of stuff readable? Do you separate your inner joins. Do you indent the SQL itself inside the string? Where do you put the comments? Please share all of the tricks in your arsenal.

• More Poll() ?'s

  - by ultifinitus

  Back again! I've been doing some async socket programming with select() on windows,and it's been working quite well. However it's only scalable up to 1024 clients.Poll() is the way to get around that limitation, and I know it works on both linux and unix. But it doesn't work with a windows system correct? I read about WsaPoll(), does it have the exact same functionality? What libraries would I have to link to in order to use it? Can I increase the socket number safely in windows with FD_SETSIZE? My end program will be on a linux server. However I am testing on a windows system right now. Should I just swap my test machine over to a linux box? (probably going to anyway) Otherwise what would you recommend to use with windows? (sorry for all of the questions, I am doing research on my own, I promise =D)

• Open default browser as standard user (C++)

  - by Disco

  I'm currently using ShellExecute "open" to open a URL in the user's browser, but running into a bit of trouble in Win7 and Vista because the program runs elevated as a service. When ShellExecute opens the browser, it seems to read the "Local Admin" profile instead of the user's. So for example, if the user at the keyboard has Firefox as his default browser, it may open IE (which is the admin's default). I know that the "runas" verb can be used to elevate, but how do you do it the other way around? Is there a way to open a URL in the default browser on a standard user's desktop from a service?
