• Memory leak using (void) alloc

  - by Rudiger

  I have seen a similar line of code floating about in Apples code: (void)[[URLRequest alloc] initializeRequestWithValues:postBody url:verifySession httpHeader:nil delegate:self]; URLRequest is my own custom class. I didn't write this and I think the guy that did just grabbed it from Apple's example. To me this should leak and when I test it I'm pretty sure it leaks 16 bytes. Would it? I know how to fix it if it does but wasn't sure as it was taken from Apple's code.

• Why touching "d_name" makes calls to readdir() fail?

  - by Sarah Mani

  Hi, I'm trying to write a little helper for Windows which eventually will accept a file extension as an argument and return the number of files of that kind in the current directory. To do so, I'm reading the file entries in the directories and after getting the extension I'd like to convert it to lowercase to compare it with the yet-to-add specified argument. When converting the extension to lowercase I found that touching even a duplicate string of the d_name variable will cause a strange behaviour, like no more calls to readdir are called. Here is the code I'm using right now (the commented code is preliminary) and outputs for a given directory: #include <ctype.h> #include <dirent.h> #include <stdio.h> #include <string.h> char * strrch(char *string, size_t elements, char character) { char *reverse = string + elements; while (--reverse != string) if (*reverse == character) return reverse; return NULL; } void test(char *string) { // Even being a duplicate will make it fail: char *str = strdup(string); printf("Strings: %s %s\n", string, str); *str = 'a'; printf("Strings: %s %s\n", string, str); //unsigned short int i = 0; //for (; str[i] != '\0', str++; i++) // str[i] = tolower((unsigned char) str[i]); //puts(str); } int main(int argc, char **argv) { DIR *directory; struct dirent *element; if (directory = opendir(".")) { while (element = readdir(directory)) test(strrch(element->d_name, element->d_namlen, '.')); closedir(directory); puts(NULL); } else puts("Couldn't open the directory.\n"); } Output without modifying the duplicate (modification and the second printf call commented): Strings: (null) (null) Strings: . . Strings: .exe .exe Strings: .pdf .pdf Strings: .c .c Strings: .ini .ini Strings: .pdf .pdf Strings: .pdf .pdf Strings: .pdf .pdf Strings: .flac .flac Strings: .FLAC .FLAC Strings: .lnk .lnk Strings: .URL .URL Output of the same directory (with the code above, with the 2 printfs): Strings: (null) (null) Is there anything wrong? Is it a compiler issue? I'm using GCC 4.4.3 in Windows (MinGW) right now. Thank you very much for your help. By the way, is there any other way to work with files and directories in a Windows environment not using the POSIX functions?

• Release another user's lock obtained with sp_getapplock on SQL Server

  - by joshperry

  We have a system that uses sp_getapplock to create an exclusive mutex any time someone opens an order in the GUI. This is used to prevent multiple people from making changes to an order simultaneously. Sometimes people will open an order and go home, leaving it open. This effectively blocks anyone from being able to make changes to the order. I then get emails, calls and end up doing a kill <spid> in enterprise manager. Obviously I've gotten sick of this and want to make a quick self-service webform. The main problem I've run into is that kill requires sysadmin privileges, which I do not want to give to the user that the our website runs as. I have tried sp_releaseapplock but this doesn't let you release another user's lock (even when calling it as a sysadmin). So, finally my question; does anyone know of an alternative method to release a lock that was obtained by another user using sp_getapplock?

• VirtualTreeView add roots with Threads

  - by Benjamin Weiss

  I would like to add roots to a VirtualTreeView http://www.delphi-gems.com/index.php/controls/virtual-treeview with a thread like this: function AddRoot ( p : TForm1 ) : Integer; stdcall; begin p.VirtualStringTree1.AddChild(NIL); end; var Dummy : DWORD; i : Integer; begin for i := 0 to 2000 do begin CloseHandle(CreateThread(NIL,0, @ADDROOT, Self,0, Dummy)); end; end; The reason for this is that I want to add all connections from my INDY Server to the TreeView. Indy's onexecute/onconnect get's called as a thread. So if 3+ connections come in at the same time the app crashes due to the TreeView. Same is if a client gets disconnected and I want to delete the Node. I am using Delphi7 and Indy9 Any Idea how to fix that?

• Detecting rotation to landscape manually

  - by Thomas Joos

  hi all, I am working on an iPhone application based on UITabBarController and UIViewControllers for each page. The app needs to run in portrait mode only, so every view controller + app delegate goes with this line of code: (BOOL)shouldAutorotateToInterfaceOrientation: (UIInterfaceOrientation)interfaceOrientation { return (interfaceOrientation == UIInterfaceOrientationPortrait); } There is one view controller where I would like to pop up a UIImageView when the iPhone is rotaed to landscapeleft. The design of the image looks landscape, although the width and height are 320x460 ( so its portrait ). How can/should I detect this type of rotation manually, just in this specific view controller, withouth having an auto rotation on the entire view? Thomas UPDATE: Thanks! I added this listener in the viewDidLoad: [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(didRotate:)name:UIDeviceOrientationDidChangeNotification object:nil]; the didRotate looks like this: (void) didRotate:(NSNotification *)notification { UIDeviceOrientation orientation = [[UIDevice currentDevice] orientation]; if (orientation == UIDeviceOrientationLandscapeLeft) { //your code here } }

• UITabBarController With UINavigationController "more" Tab Issue

  - by Medlay

  UITabBarController with UINavigationController "more" tab issue There is a problem with using UINavigationController in UITabBarController. I have a TabBar  with 6 items. Of course, a standart item "more" appears, and there are two UINavigationControllers that didn't fit in a TabBar. The core of the problem is: when I'm working with visible items (a first four), UIViewController can be pushed  in an UINavigationController: [self.navigationController pushViewController:userDataViewController animated:YES]; If you call on in "more" and rearrange items in such way, that a visible UINavigationController gets into "more", when calling on it userDataViewController appears.  This  userDataViewController is the last, which has got in a stack and a Back button leads back to "more", but not to the controllers, that were before a userDataViewController appeared. I understand that in fact a selector pushViewController is called from "more", and it pushes my UINavigationController in a stack, and it's not good. Maybe, someone has faced such problem and could help me to solve it? Thank you forward.

• Timer with random seconds ¿How to update the random seconds?

  - by benLIVE

  I have a timer "tmr_sendCesta" which must be called each x seconds between 1 and 3 seconds. The problem is the timer "tmr_sendCesta" is called only one time, and the random seconds is never updated. I need to call the function "createCesta" each x seconds randomly. Any idea how to do it? function createCesta() cesta = display.newImageRect("cesta.png", 100, 55) cesta.x = -110 cesta.y = screenH - 110 cesta.name = "cesta" physics.addBody( cesta, physicsData:get("cestaSmall")) grupoCesta:insert(cesta) transition.to(cesta, {time = 4000, x = screenW + 110}) end function scene:enterScene( event ) local group = self.view physics.start() Runtime:addEventListener("touch", touchScreen) Runtime:addEventListener( "collision", onCollision ) tmr_sendCesta = timer.performWithDelay((math.random(1000, 3000), randomCesta, 0) end

• Writing a rails validator with integer

  - by user297008

  I was trying to write a validation for Rails to ensure that a price entered on a form was greater than zero. It works…sort of. The problem is that when I run it, val is turned into an integer, so it thinks that .99 is less than .1. What's going on, and how should I fix the code? class Product < ActiveRecord::Base protected def self.validates_greater_than_zero(*attr_names) validates_each(attr_names) do |record, attr, val| record.errors.add(attr, "should be at least 0.01 (current val = #{val.to_f})") if val.nil? || val < 0.01 end end public validates_presence_of :title, :description, :image_url validates_numericality_of :price validates_greater_than_zero :price end

• Drawbacks of WebFormsMVP?

  - by Tony_Henrich

  While ASP.NET MVC seems to be a viable technology praised by a lot of developers, I can't seem to find enough reasons to devote my energy and time for it. The main reason is that I don't find enough .NET jobs asking for it. Companies still use WebForms and it works just fine for them. I am not self employed where I get to choose the technology I like. I would rather use my time improve my skills in SilverLight, JQuery, Javascript, SQL, LINQ.. etc. Even Photoshop! So I got interested in webformsmvp.com. I get to still use WebForms and use better testing methods. Anyone who has experience with it can tell me what they didn't like about it?

• MKMapView not centered on pin

  - by Val Smith

  Hi all, I have an mkmapview that i'm currently adding pins to, but for some reason when I call [mapView setRegion:[detailItem coordinateRegion] animated:YES]; the pin is off-centered (toward the right side of the screen) on the map. Here is the code for [deailItem coordinateRegion]: - (MKCoordinateRegion)coordinateRegion { MKCoordinateRegion region = { {0.0, 0.0 }, { 0.0, 0.0 } }; region.center = self.coordinate; region.span.longitudeDelta = 0.0075f; region.span.latitudeDelta = 0.0075f; return (region); } I'm setting the coordinateRegion's center to the object's x,y coordinate, so why is it off-center on the map? I feel like there's something I'm missing here... ::Val::

• Visual Studio 2008/2010 & SQL Server 2008 on Windows 7 Home Premium

  - by Steve

  Are there any limitations with respect to developing ASP.NET and WPF apps using VS 2008/2010 and SQL Server 2008 on Windows 7 Home Premium? I know you can run IIS 7.5 on Home Premium. I Googled and Binged on Home Premium and VS/SQL Server and couldn't find much. It doesn't look like the features missing from Home Premium, domain joining, xp mode, etc... shouldn't prevent one from running and developing in VS/SQL Server. Update I did discover one limitation w/IIS 7.5 and it applies to all versions of Windows 7 I think. You can't create your own self signed SSL certificate specifying a name other than the machine name. You're stuck with your machine name which isn't that big a deal, but it is a change from previous versions.

• iPhone: NSAlert Delegate Method Never Called

  - by Marco

  Hello, I have implemented an NSAlert but the delegate method didDissmissWithButton is never called. This code evokes the NSAlert: NSString *title = [NSString stringWithFormat:@"Keine Internetverbindung"]; NSString *alertMessage = [NSString stringWithFormat:@"Es konnte keine Verbindung zu www.sip.de aufgebaut werden!"]; NSString *ok = [NSString stringWithFormat:@"Ok"]; UIAlertView *alert = [[UIAlertView alloc] initWithTitle:title message:alertMessage delegate:self cancelButtonTitle:ok otherButtonTitles:nil]; [alert show]; [alert release]; and this is the NSAlert delegate method: - (void)alertView:(UIAlertView *)alertView didDisMissWithButtonIndex:(NSInteger)buttonIndex{ exit(3); } The method is never called, what is my mistake?

• Why can't I set a custom color-tint for the UINavigationBar?

  - by mobibob

  I want to change the color on the navigation bar and the documentation states not to attempt to change the 'alpha' value. So, how can I set a color that is not the SDK defined values (e.g., [UIColor redColor], brownColor, etc.) if all the constructors provide an alpha value? I tried getting the current alpha value but that did not help. When I use a custom color, it causes the navigation bar to look like an x-ray (a scraggy, black-on-white). [self.navigationController.navigationBar setTintColor: [UIColor brownColor]];

• Send instance method to module

  - by Matchu

  Given the following module, module Foo def bar :baz end end def send_to_foo(method) # ...? end send_to_foo(:bar) # => :baz What code should go in send_to_foo to make the last line work as expected? (send_to_foo is obviously not how I would implement this; it just makes clearer what I'm looking for.) I expected Foo.send(:bar) to work at first, but it makes sense that it doesn't. It would if the method were defined as def self.bar, but that's no fun.

• Tools to create maximum velocity in a .NET dev team

  - by Søren Spelling Lund

  If you were to self-fund a software project which tools, frameworks, components would you employ to ensure maximum productivity for the dev team and that the "real" problem is being worked on. What I'm looking for are low friction tools which get the job done with a minimum of fuss. Tools I'd characterize as such are SVN/TortioseSVN, ReSharper, VS itself. I'm looking for frameworks which solve the problems inherient in all software projects like ORM, logging, UI frameworks/components. An example on the UI side would be ASP.NET MVC vs WebForms vs MonoRail.

• Lightbox for embeddable JavaScript widget? Like Feedback tabs for UserVoice/GetSatisfaction

  - by Eliot Sykes

  There are so many lightboxes to choose from, I'm looking for a very lightweight one to use in an embedded javascript widget that would be used on a number of different web sites. This would work in a similar way to the GetSatisfaction/UserVoice feedback tab. Here are the requirements for the lightbox: Very small javascript download (animation not needed) Self contained, not dependent on any libraries such as jquery, etc. Works in major browsers Lightbox displays HTML content from a given URL Close button (like GetSatisfaction or UserVoice) Dims background Avoids javascript namespace conflicts (or can easily be made to avoid them) CSS styling of lightbox does not interfere with site styling Have you used an existing lightbox scripts for this same purpose with similar requirements? Did you roll your own? Insights welcome! Thanks, Eliot

When you goto the secure page it's acting like I have a self-signed certificate and I don't. I have the host configured like so ServerAdmin [email protected] DocumentRoot "/path/to/site" Servername www.mydomain.com ServerAlias mydomain.com DirectoryIndex index.cfm index.htm SSLEngine on SSLCipherSuite ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP:+eNULL SSLCertificateFile /etc/httpd/path/to/mydomain.com.crt SSLCertificateKeyFile /etc/httpd/path/to/www.mydomain.com.key SSLCertificateChainFile /etc/httpd/path/to/gd_bundle.crt Apache starts with no errors and I can't seem to find anything meaningful in any of the logs. It's got to be something minor but I can't seem to see it. It's an updated Centos/Apache VM. I have worn Google out.
