  • Using NSThread to solve waiting for image from URL on the iPhone

    - by james.ingham
    So I have the following code in a method which I want to set a UIImageView image to that of one from an online source: [NSThread detachNewThreadSelector:@selector(loadImage) toTarget:self withObject:nil]; Then in the method called by the thread I have this: - (void) loadImage { NSURL *url = [NSURL URLWithString:logoPath]; // logoPath is an NSString with path details NSData *data = [NSData dataWithContentsOfURL:url]; logoImage.image = [UIImage imageWithData:data]; } This works great however I get many warnings within the Debugger Console along the lines of: 2010-05-10 14:30:14.052 ProjectTitle[2930:633f] * _NSAutoreleaseNoPool(): Object 0x169d30 of class NSHTTPURLResponse autoreleased with no pool in place - just leaking This occurs many times each time I call the new thread and then eventually, under no pattern, after calling a few of these threads I get the classic 'EXC_BAD_ACCESS' run-time error. I understand that this is happening because I'm not retaining the object but how can I solve this with the code in 'loadImage' shown above? Thanks

  • changing the serialization procedure for a graph of objects (.net framework)

    - by pierusch
    Hello I'm developing a scientific application using .net framework. The application depends heavily upon a large data structure (a tree like structure) that has been serialized using a standard binaryformatter object. The graph structure looks like this: <serializable()>Public class BigObjet inherits list(of smallObject) end class <serializable()>public class smallObject inherits list(of otherSmallerObjects) end class ... The binaryFormatter object does a nice job but it's not optimized at all and the entire data structure reaches around 100Mb on my filesystem. Deserialization works too but it's pretty slow (around 30seconds on my quad core). I've found a nice .dll on codeproject (see "optimizing serialization...") so I wrote a modified version of the classes above overriding the default serialization/deserialization procedure reaching very good results. The problem is this: I can't lose the data previosly serialized with the old version and I'd like to be able to use the new serialization/deserialization method. I have some ideas but I'm pretty sure someone will be able to give me a proper and better advice ! use an "helper" graph of objects who takes care of the entire serialization/deserialization procedure reading data from the old format and converting them into the classes I nedd. This could work but the binaryformatter "needs" to know the types being serialized so........ :( modify the "old" graph to include a modified version of serialization procedure...so I'll be able to deserialize old file and save them with the new format......this doesn't sound too good imho. well any help will be higly highly appreciated :)

  • get pure text form odt file in console

    - by naugtur
    I am looking for a small linux tool that would be able to extract text from odt file. It just needs to be human-readable and it can have problems with complicated objects etc. It's almost a duplicate of this question but I need it to be small and have no dependencies on OpenOffice or X server I remember having a 1MB MS-DOS program that could render .doc files quite readibly (with some weird markup getting through from time to time), so i expect it to be possible in the linux world too ;)

  • How to convert Xml files to Text Files 2

    - by John
    Hi all, I have around 8000 xml files that needs to be converted into text files. The text file must contain title, description and keywords of the xml file without the tags and removing other elements and attributes as well. In other words, i need to create 8000 text files containing the title,description and keywords of the xml file. I need codings for this to be done systematically. Any help would be greatly appreciated. Thanks in advance. Hey all thank you all so so much with your replies. Here's a sample of what my xml looks like: <?xml version="1.0"?> <metadata> <identifier>43productionsNightatthegraveyard</identifier> <title>Night at the graveyard</title> <collection>opensource_movies</collection> <mediatype>movies</mediatype> <resource>movies</resource> <upload_application appid="ccPublisher" version="2.2.1"/> <uploader>[email protected]</uploader> <description>una noche en el cementerio (terror)</description> <license>http://creativecommons.org/licenses/by-nc/3.0/</license> <title>Night at the graveyard</title> <format>Video</format> <adder>[email protected]</adder> <licenseurl>http://creativecommons.org/licenses/by-nc/3.0/</licenseurl> <year>2007</year> <keywords>Night,at,the,graveyard,43,productions</keywords> <holder>43 productions</holder> <publicdate>2007-04-11 19:52:28</publicdate> </metadata> And this would be the output: una noche en el cementerio (terror) Night at the graveyard Night,at,the,graveyard,43,productions This need to be saved with the same name but in text format. Thanks all so much if any more suggestions would be much appreciated.

  • How to convert between different currencies?

    - by sil3nt
    Hey there, this is part of a question i got in class, im at the final stretch but this has become a major problem. In it im given a certain value which is called the "gold value" and it is 40.5, this value changes in input. and i have these constants const int RUBIES_PER_DIAMOND = 5; // relative values. * const int EMERALDS_PER_RUBY = 2; const int GOLDS_PER_EMERALDS = 5; const int SILVERS_PER_GOLD = 4; const int COPPERS_PER_SILVER = 5; const int DIAMOND_VALUE = 50; // gold values. * const int RUBY_VALUE = 10; const int EMERALD_VALUE = 5; const float SILVER_VALUE = 0.25; const float COPPER_VALUE = 0.05; which means that basically for every diamond there are 5 rubies, and for every ruby there are 2 emeralds. So on and so forth. and the "gold value" for every diamond for example is 50 (diamond value = 50) this is how much one diamond is worth in golds. my problem is converting 40.5 into these diamonds and ruby values. I know the answer is 4rubies and 2silvers but how do i write the algorithm for this so that it gives the best estimate for every goldvalue that comes along?? please help!, im at my wits end

  • Changing background image on accordion change - jQuery Ui

    - by Coughlin
    I am using this code: $('.ui-accordion').bind('accordionchange', function(event, ui) { $(this).next().next().css({'background-image':'images/green-bg.jpg'}); //ui.newHeader // jQuery object, activated header //ui.oldHeader // jQuery object, previous header // ui.newContent // jQuery object, activated content // ui.oldContent // jQuery object, previous content }); To try to change the background image of the PREVIOUS header after it changes. I see that the jquery docs supply the object for oldHeader, but I am trying to change the CSS of that element. Any ideas how I would do that? So You go to the next one it goes green, then the current one is going to be red. Thanks, Ryan

  • Getting true video Height/Width from ASF videos

    - by David
    I am trying to convert an ASF video with FFMPEG using an interface called mediahandler. The issue is, the metadata on the ASF video appears to be corrupt. It states that the video is 640x240, and 4:3 aspect ratio. The aspect ratio is correct, but obviously the resolution is not. This causes the converter to incorrectly scale the video, because it uses the resolution to determine the original aspect ratio. I am able to get the aspect ratio metadata, but I'm not sure this solves the issue, because I would think that if the resolution could be incorrect, then so could the aspect ratio metadata. So, is there any way to get the actual height/width? It appears that players like VLC have no issue with this. How do I do such a thing w/ FFMPEG?

    I'm converting from C# this LINQ expression. However, it does not seem to work. C# return (from w in fishSticks group w by w.FishQty into g orderby g.Key descending select g).First().First(); VB Return (From w In fishSticks Group w By w.FishQty Into g() Order By g.Key Descending Select g).First().First() Visual Studio turns g into g() itself and then gives me this error: Definition of method 'g' is not accessible in this context.

  • Background Image w/Quartz Drawing

    - by James
    I'm using Quartz to do some basic drawing. I recently decided I wanted a background image for my app. So I went into my XIB file and added a UIImageView and set the background, looks good. However, when I run it, the Z-Index of the image is above my drawing. I googled a bit and found that you can do Layout Send to Back in IB...but that option is grayed out to me when I have my UIImageView selected. Is there an easy way to move this UIImageView permanently to the background? Is there perhaps an alternate method to doing this that I should consider? Thanks

  • Compatible types and structures in C

    - by Oli Charlesworth
    I have the following code: int main(void) { struct { int x; } a, b; struct { int x; } c; struct { int x; } *p; b = a; /* OK */ c = a; /* Doesn't work */ p = &a; /* Doesn't work */ return 0; } which fails to compile under GCC (3.4.6), with the following error: test.c:8: error: incompatible types in assignment test.c:9: warning: assignment from incompatible pointer type Now, from what I understand (admittedly from the C99 standard), is that a and c should be compatible types, as they fulfill all the criteria in section 6.2.7, paragraph 1. I've tried compiling with std=c99, to no avail. Presumably my interpretation of the standard is wrong?

  • Safe image uploading with PHP

    - by directedition
    I want my site to have a feature for users to upload images, but I want to do it safely. Namely, I want to strip the EXIF data and any malicious code that could be in their image. I was thinking of a way to do this involving direct manipulation of the file, but it struck me, would it make more sense to just convert the image they provide to BMP and then convert that back to the original format? It would suffer a generational loss, but I believe that would meet my project's requirements. BMP doesn't contain EXIF, does it? And the reprocessing should strip any malicious content.

  • Convert MSAccess Project Management Application to PHP/MySQL: Which Methodology?

    - by zzapper
    I've got to convert a not terribly complicated bespoke project management system from MsAccess Application to PHP/MySQL. I've been programming for donkey's years but embarrassingly know practically nothing about modern methodologies. So the old 'learning curve' versus 'improved efficiency' conundrum rears its ugly head once again. Although I've Googled up some stuff I don't want to prejudice your suggestions, where would you start, I'm at your mercy?

  • Avoid incompatible pointer warning when dealing with double-indirection

    - by fnawothnig
    Assuming this program: #include <stdio.h> #include <string.h> static void ring_pool_alloc(void **p, size_t n) { static unsigned char pool[256], i = 0; *p = &pool[i]; i += n; } int main(void) { char *str; ring_pool_alloc(&str, 7); strcpy(str, "foobar"); printf("%s\n", str); return 0; } ... is it possible to somehow avoid the GCC warning test.c:12: warning: passing argument 1 of ‘ring_pool_alloc’ from incompatible pointer type test.c:4: note: expected ‘void **’ but argument is of type ‘char **’ ... without casting to (void**) (or simply disabling the compatibility checks)? Because I would very much like to keep compatibility warnings regarding indirection-level...

  • Preloading CSS Background Images

    - by Peanuts
    Hello guys, I have a hidden contact form which is deployed clicking on a button. Its fields are set as CSS background images, and they always appears a bit later than the div that have been toggled. I was using this snippet in the <head> section, but with no luck (after I cleared the cache) : <script type="text/javascript"> $(document).ready(function() { pic = new Image(); pic2 = new Image(); pic3 = new Image(); pic.src="<?php bloginfo('template_directory'); ?>/images/inputs/input1.png"; pic2.src="<?php bloginfo('template_directory'); ?>/images/inputs/input2.png"; pic3.src="<?php bloginfo('template_directory'); ?>/images/inputs/input3.png"; }); </script> I'm using jQuery as my library, and it would be cool if I could use it as well for arranging this issue. Thanks for your thoughs.

  • Implementing "View as HTML" for Word and PDF documents on an intranet

    I am looking for a way to implement "View as HTML" (as seen in e.g. GMail) for Microsoft Office and Adobe PDF documents stored in an intranet. Can anyone recommend approaches for this? The intranet consists of multiple .NET sites, so I would prefer a .NET library (one that doesn't launch MS Word on the server) for this capability, but any kind of arrangement is welcome.

  • Creating Thumbnails with CFImage Aborting Because of Server Load?

    - by nephilite
    I am uploading in image via a form and I want to, in addition to saving the image, save a variety of thumbnails in both png and jpg format. To do this I am using the code below. The initial image uploads fine but then, after spinning for a moment I get an error of: "Request aborted due to heavy system load." (from my host crystaltech), and none of the thumbnails have made it through. I've tried it with even just one resize (and no converts) and it still fails. What am I doing wrong? This issue is somewhat urgent....Thanks! ` <cffile action="upload" destination="#Application.filePath#Icons\#app#Icon.png" filefield="Icon" nameconflict="overwrite"> <cfimage source="#Application.filePath#Icons\#app#Icon.png" action="resize" width="50%" height="50%" destination="#Application.filePath#Icons\#app#Icon_Half.png" overwrite="yes"> <cfimage source="#Application.filePath#Icons\#app#Icon.png" action="resize" width="25%" height="25%" destination="#Application.filePath#Icons\#app#Icon_Quarter.png" overwrite="yes"> <cfimage source="#Application.filePath#Icons\#app#Icon.png" action="convert" destination="#Application.filePath#Icons\#app#Icon.jpg"> <cfimage source="#Application.filePath#Icons\#app#Icon_Half.png" action="convert" destination="#Application.filePath#Icons\#app#Icon_Half.jpg"> <cfimage source="#Application.filePath#Icons\#app#Icon_Quarter.png" action="convert" destination="#Application.filePath#Icons\#app#Icon_Quarter.jpg"> `
