  • Differences between matrix implementation in C

    - by tempy
    I created two 2D arrays (matrix) in C in two different ways. I don't understand the difference between the way they're represented in the memory, and the reason why I can't refer to them in the same way: scanf("%d", &intMatrix1[i][j]); //can't refer as &intMatrix1[(i * lines)+j]) scanf("%d", &intMatrix2[(i * lines)+j]); //can't refer as &intMatrix2[i][j]) What is the difference between the ways these two arrays are implemented and why do I have to refer to them differently? How do I refer to an element in each of the arrays in the same way (?????? in my printMatrix function)? int main() { int **intMatrix1; int *intMatrix2; int i, j, lines, columns; lines = 3; columns = 2; /************************* intMatrix1 ****************************/ intMatrix1 = (int **)malloc(lines * sizeof(int *)); for (i = 0; i < lines; ++i) intMatrix1[i] = (int *)malloc(columns * sizeof(int)); for (i = 0; i < lines; ++i) { for (j = 0; j < columns; ++j) { printf("Type a number for intMatrix1[%d][%d]\t", i, j); scanf("%d", &intMatrix1[i][j]); } } /************************* intMatrix2 ****************************/ intMatrix2 = (int *)malloc(lines * columns * sizeof(int)); for (i = 0; i < lines; ++i) { for (j = 0; j < columns; ++j) { printf("Type a number for intMatrix2[%d][%d]\t", i, j); scanf("%d", &intMatrix2[(i * lines)+j]); } } /************** printing intMatrix1 & intMatrix2 ****************/ printf("intMatrix1:\n\n"); printMatrix(*intMatrix1, lines, columns); printf("intMatrix2:\n\n"); printMatrix(intMatrix2, lines, columns); } /************************* printMatrix ****************************/ void printMatrix(int *ptArray, int h, int w) { int i, j; printf("Printing matrix...\n\n\n"); for (i = 0; i < h; ++i) for (j = 0; j < w; ++j) printf("array[%d][%d] ==============> %d\n, i, j, ??????); }

  • Python tkInter text entry validation

    - by meade
    I'm trying to validate the entry of text using Python/tkInter def validate_text(): return False text = Entry(textframe, validate="focusout", validatecommand=validate_text) where validate_text is the function - I've tried always returning False and always returning True and there's no difference in the outcome..? Is there a set of arguments in the function that I need to include? Edit - changed from NONE to focusout...still not working

  • Should I use my models in a library?

    - by Piers
    I've got my auth library in codeigniter which accesses the database to check to see if the email/password combination is correct. If I'm sticking to the MVC practice, should I move the function that interacts with the database to my model, or is it best practice to leave it where it is so I can use it in the future? Doesn't make much difference to me, other than the fact I'd have to re-write the library and create the function in my model, but if that's the way it should be then so be it.

  • what is the point of return in ruby?

    - by Sam
    What is the difference between return and just putting a variable such as the following: return def write_code(number_of_errors) if number_of_errors > 1 mood = "WTF" else mood = "No Problem" end mood end no return def write_code(number_of_errors) if number_of_errors > 1 mood = "WTF" else mood = puts "No Problem" end return mood end

  • Django: FloatField or DecimalFied for Currency ?

    - by Hellnar
    I am curious which one would be better fitting as a currency field ? I will do simple operations such as taking difference, the percentage between old and new prices. I plan to keep two digits after the zero (ie 10.50) and majority of the time if these digits are zero, I will be hiding these numbers and display it as "10"

    I'm experitmenting with the Twitter API (OAuth). I have a test bed that can tweet from my dev box, but fails in production. I get a status code of 424 returned when trying to tweet.

  • add more than 30 days with Calendar's add() method in Java

    - by Haes
    Hi, I'm not quite sure what field to use when adding more than 30 days to a Java Calendar object. Is there any difference in between Calendar.DAY_OF_MONTH and Calendar.DAY_OF_YEAR? Example: GregorianCalendar d = new GregorianCalendar(); d.add(Calendar.DAY_OF_YEAR, 90); vs GregorianCalendar d = new GregorianCalendar(); d.add(Calendar.DAY_OF_MONTH, 90); Thanks.

  • Why is my number being rounded incorrectly?

    - by izb
    This feels like the kind of code that only fails in-situ, but I will attempt to adapt it into a code snippet that represents what I'm seeing. float f = myFloat * myConstInt; /* Where myFloat==13.45, and myConstInt==20 */ int i = (int)f; int i2 = (int)(myFloat * myConstInt); After stepping through the code, i==269, and i2==268. What's going on here to account for the difference?

  • Managed DirectX as a starting point

    - by numerical25
    I know the difference between manage and unmanaged DirectX. My question is if I decided to do managed directX as a starting point, would it help me to better understand unmanaged DirectX. Honestly, the only thing I see different about the 2 is how you initiate and access resources. Matrix Math is Matrix no matter what so If I learn it in managed, then I should be fine in unmanaged

  • [r] Converting unix seconds in milliseconds to POSIXct/POSIXlt

    - by signalseeker
    Why do I see a difference when I convert a unix timestamp to datetime object in R? > as.POSIXlt(1268736919, origin="1970-01-01", tz="America/New_York") [1] "2010-03-16 06:55:19 EDT" > as.POSIXct(1268736919, origin="1970-01-01", tz="America/New_York") [1] "2010-03-16 11:55:19 EDT" The result from POSIXlt is actually correct. Also, is there a way to do this conversion without specifying the origin? Thanks

  • Does UserId data type affect FormsAuthentication.SetAuthCookie(UserId.ToString(), false)?

    - by FreshCode
    Does the original data type of the username string in a call to FormsAuthentication.SetAuthCookie(...) make any difference with regards to security or code maintainability? As I understand it, the cookie is encrypted and used to identify a user on each request. I'm curious whether it should affect the design of the primary key on my Users table in my database, eg. Guid vs int or a unique username string.

  • Is it bad to explicitly compare against boolean constants e.g. if (b == false) in Java?

    - by polygenelubricants
    Is it bad to write: if (b == false) //... while (b != true) //... Is it always better to instead write: if (!b) //... while (!b) //... Presumably there is no difference in performance (or is there?), but how do you weigh the explicitness, the conciseness, the clarity, the readability, etc between the two? Note: the variable name b is just used as an example, ala foo and bar.

  • Equivalent of System.Windows.Forms.Cursor in Web Application

    - by Vishwa
    Hi I have a code in windows application now i am trying to implement in web Application but it is showimg that it ths no cursor class (System.Windows.Forms.Cursor )so..wat is the equivalent in web application. Here is my code private void btnGo_Click(System.Object sender, System.EventArgs e) { this.Cursor = Cursors.WaitCursor; Application.DoEvents(); // Load the images. Bitmap bm1 = (Bitmap) (Image.FromFile(txtFile1.Text)); Bitmap bm2 = (Bitmap) (Image.FromFile(txtFile2.Text)); // Make a difference image. int wid = Math.Min(bm1.Width, bm2.Width); int hgt = Math.Min(bm1.Height, bm2.Height); Bitmap bm3 = new Bitmap(wid, hgt); // Create the difference image. bool are_identical = true; int r1; int g1; int b1; int r2; int g2; int b2; int r3; int g3; int b3; Color eq_color = Color.White; Color ne_color = Color.Transparent; for (int x = 0; x <= wid - 1; x++) { for (int y = 0; y <= hgt - 1; y++) { if (bm1.GetPixel(x, y).Equals(bm2.GetPixel(x, y))) { bm3.SetPixel(x, y, eq_color); } else { bm1.SetPixel(x, y, ne_color); are_identical = false; } } } // Display the result. picResult.Image = bm1; Bitmap Logo = new Bitmap(picResult.Image); Logo.MakeTransparent(Logo.GetPixel(1, 1)); picResult.Image = (Image)Logo; this.Cursor = Cursors.Default; if ((bm1.Width != bm2.Width) || (bm1.Height != bm2.Height)) { are_identical = false; } if (are_identical) { MessageBox.Show("The images are identical"); } else { MessageBox.Show("The images are different"); } //bm1.Dispose() // bm2.Dispose() }

  • Read Excel 2007 file (.xlsx) in C#

    - by Safiullah
    My code was quite sufficient for reading xls file in C# (using Microsoft.Jet.Oledb.4.0) but when I tried to read Office 2007 (xlsx) file, it didn't work. I searched and found that it could be read using Microsoft.ACE.Oledb.12, I tried and it worked. Can anyone tell me the difference between the two ? and why xlsx file can not be read using Microsoft.Jet.Oledb.4.0 Provider.

  • Hibernate @Transactional not starting transaction

    - by rhinds
    I have a web app using Hibernate, and I am attempting to persist some data, but it is failing to persist within a Transaction despite using the @Transactional annotation. My service class is as follows: @Service("profileService") public class ProfileService { private EntityManager entityManager; @Autowired private AccountService accountService; @Autowired private ProfileDAOImpl profileDao; @PersistenceContext public void setEntityManager(EntityManager em) { this.entityManager = em; } @Transactional public void addConnectionToAccount(SocialConnection sc) { entityManager.persist(sc); } } The addConnectionToAccount() method is being called from another Spring bean in a normal method, and the ProfileService class is currently being injected there: public class HibernateConnectionRepository implements ConnectionRepository { @Inject private ProfileService profileService; @Override @Transactional public void addConnection(SocialConnection sc) { try { profileService.addConnectionToAccount(accountId, sc); } catch (Exception e) { e.printStackTrace(); } } I tried putting the @Transactional annotation on the calling method in the vain hope that it might make a difference but nothing. Previously I have experienced problems like this its been because the object being persisted does not satisfy table restrictions (such as non-nullable columns as null) or because the method is being called from within the same class and the calling method is not Transactional, but neither of those are the case here.. Any ideas? it just fails silently, the logs are as follows: 2012-03-26 22:25:04,702 [http-bio-8085-exec-9] DEBUG com.mchange.v2.resourcepool.BasicResourcePool - trace com.mchange.v2.resourcepool.BasicResourcePool@1bc25c8 [managed: 3, unused: 2, excluded: 0] (e.g. com.mchange.v2.c3p0.impl.NewPooledConnection@e5b006) 2012-03-26 22:25:04,710 [http-bio-8085-exec-9] DEBUG org.hibernate.SQL - select SEQ_COUNT from SEQUENCE where SEQ_NAME = 'PO_SEQ' for update 2012-03-26 22:25:04,711 [http-bio-8085-exec-9] DEBUG org.hibernate.SQL - update SEQUENCE set SEQ_COUNT = ? where SEQ_COUNT = ? and SEQ_NAME = 'PO_SEQ' 2012-03-26 22:25:04,723 [http-bio-8085-exec-9] DEBUG com.mchange.v2.resourcepool.BasicResourcePool - trace com.mchange.v2.resourcepool.BasicResourcePool@1bc25c8 [managed: 3, unused: 2, excluded: 0] (e.g. com.mchange.v2.c3p0.impl.NewPooledConnection@e5b006) 2012-03-26 22:25:04,723 [http-bio-8085-exec-9] DEBUG org.hibernate.event.internal.AbstractSaveEventListener - Generated identifier: 2200, using strategy: org.hibernate.id.MultipleHiLoPerTableGenerator UPDATE Also wanted to mention that the HibernateConnectionRepository bean is not annotated and is actually being configured in an @Configuration class (if this makes any difference? not used @Configuration classes much). The method to create the bean is as follows: @Bean @Scope(value = "request", proxyMode = ScopedProxyMode.INTERFACES) public ConnectionRepository connectionRepository() { Authentication authentication = SecurityContextHolder.getContext().getAuthentication(); if (authentication == null) { throw new IllegalStateException("Unable to get a ConnectionRepository: no user signed in"); } ApplicationUser user = (ApplicationUser) authentication.getPrincipal(); return usersConnectionRepository().createConnectionRepository(String.valueOf(user.getAccountId())); } The bean is scoped to the logged in user, but may also be created multiple times for each user..

  • WPF ClickOnce Bootstrap Dection Failure on One Machine

    - by Dexter Morgan
    Hello Friend, I've decided to use ClickOnce technology to deploy my new WPF application. By and large, ClickOnce works as advertised but I've hit a minor glitch regarding Bootstrapping and framework detection. Some background: - I'm using the standard Visual Studio-generated publish.htm page as my launch page. - The only prerequisite is the .NET Framework 4.0 Client Profile. - All clients using IE 8. - All clients already have the .NET 4.0 Client Profile installed. ClickOnce works as advertised on the vast majority of machines. The VS-generated JScript correctly detects that the framework is installed and presents the user with a Run button. The app launches just fine. I'm getting odd results on one of the machines, however. On the offending machine, the VS-generated JScript tells the user that the prereqs may not be installed -- or rather, it FAILS to detect that the framework is already installed. The "launch" link successfully launches the application but the Run link points to the bootstrapper setup.exe. Why is it failing to detect the framework on this one machine? It occurred to me that framework detection is largely a matter of examining the useragent string that's submitted by the browser. So, what you see below are two UserAgent strings. The first is from a machine where things are working properly. The second is from the offending machine. THIS ONE WORKS: 2011-01-11 15:14:14 W3SVC1 192.168.0.36 GET /publish.htm - 80 - 72.130.187.100 Mozilla/4.0+(compatible;+MSIE+8.0;+Windows+NT+6.0;+Trident/4.0;+SLCC1;+.NET+CLR+2.0.50727;+Media+Center+PC+5.0;+.NET+CLR+3.5.21022;+.NET+CLR+3.5.30729;+.NET+CLR+3.0.30729;+.NET4.0C) 304 0 0 THIS ONE DOESN'T: 2011-01-11 18:49:12 W3SVC1 192.168.0.36 GET /publish.htm - 80 - 76.212.204.169 Mozilla/4.0+(compatible;+MSIE+8.0;+Windows+NT+6.1;+WOW64;+Trident/4.0;+GTB6.6;+SLCC2;+.NET+CLR+2.0.50727;+.NET+CLR+3.5.30729;+.NET+CLR+3.0.30729;+Media+Center+PC+6.0;+.NET4.0C) 200 0 0 The useragent string of both machines clearly states, "hey the .NET 4.0 client profile is installed here" -- yet the second machine seems unable to detect it. I don't know enough about useragent strings to understand why the former works and the latter fails. The only difference as far as I can tell is that the offending machine is running 64bit. But that shouldn't make a difference. Should it? Any ideas? Dexter Morgan

  • Google map - How to escape charaters in the title of a marker in a google map?

    - by Anthony
    Say have this piece of code: var marker = new google.maps.Marker({ position: location, title: 'B&#250;fals', map: map }); This creates a marker as expected but if I hover the mouse over it I don’t see 'Búfals' as I would expect (instead I see the html code). This doesn't make any difference: var marker = new google.maps.Marker({ position: location, title: unescape('B&#250;fals'), map: map }); Any ideas? Thanks.

  • zlib gzgets extremely slow?

    - by monkeyking
    I'm doing stuff related to parsing huge globs of textfiles, and was testing what input method to use. There is not much of a difference using c++ std::ifstreams vs c FILE, According to the documentation of zlib, it supports uncompressed files, and will read the file without decompression. I'm seeing a difference from 12 seconds using non zlib to more than 4 minutes using zlib.h This I've tested doing multiple runs, so its not a disk cache issue. Am I using zlib in some wrong way? thanks #include <zlib.h> #include <cstdio> #include <cstdlib> #include <fstream> #define LENS 1000000 size_t fg(const char *fname){ fprintf(stderr,"\t-> using fgets\n"); FILE *fp =fopen(fname,"r"); size_t nLines =0; char *buffer = new char[LENS]; while(NULL!=fgets(buffer,LENS,fp)) nLines++; fprintf(stderr,"%lu\n",nLines); return nLines; } size_t is(const char *fname){ fprintf(stderr,"\t-> using ifstream\n"); std::ifstream is(fname,std::ios::in); size_t nLines =0; char *buffer = new char[LENS]; while(is. getline(buffer,LENS)) nLines++; fprintf(stderr,"%lu\n",nLines); return nLines; } size_t iz(const char *fname){ fprintf(stderr,"\t-> using zlib\n"); gzFile fp =gzopen(fname,"r"); size_t nLines =0; char *buffer = new char[LENS]; while(0!=gzgets(fp,buffer,LENS)) nLines++; fprintf(stderr,"%lu\n",nLines); return nLines; } int main(int argc,char**argv){ if(atoi(argv[2])==0) fg(argv[1]); if(atoi(argv[2])==1) is(argv[1]); if(atoi(argv[2])==2) iz(argv[1]); }
