• Help! Obj-C/Iphone programming: extracting string from html text and reading off line by line

  - by royden

  hihi, I have this html text response from a particular website: <tr><td valign="top"><img src="/icons/image2.gif" alt="[IMG]"></td><td><a href="crsdsdfs2221.jpg">crash-2221.jpg</a></td><td align="right">14-Jun-2010 14:29 Notice for every line, there is this href=".__", which is an image file with random name and random format. I would like to extract that string within the inverted commas out so that i can append it into a URL path and download the image. I've been looking through this documentation from apple: http://developer.apple.com/mac/library/documentation/cocoa/conceptual/strings/Articles/SearchingStrings.html#//apple_ref/doc/uid/20000149-CJBBGBAI on String programming but couldn't find one that fits my bill. Also after reading it, what code can I use to ensure that I will be reading the next line the next time my function is called( because I want to download the next picture). Hope some kind soul can help me out, thanks!

• How to get image from relative URL in C#, the image cannot be in the project

  - by red-X

  I have a project where I'm loading relative image Uri's from an xml file. I'm loading the image like this: if (child.Name == "photo" && child.Attributes["href"] != null && File.Exists(child.Attributes["href"].Value)) { Image image = new Image(); image.Source = new BitmapImage(new Uri(child.Attributes["href"].Value, UriKind.RelativeOrAbsolute)); images.Add(image); } Where the "child" object is an XmlNode which could looks like this <photo name="info" href="Resources\Content\test.png"/> During debug it seemd images is filled with actual images but when I want to see them in any way it shows nothing. Weird thing is when I include the images in my project it does work, I however dont want to do that since my point for using an xml file is so that it would be lost since you'd have to rebuild the program anyway after a change.

• Auto pointer for unsigned char array?

  - by Gianluca

  I'd need a class like std::auto_ptr for an array of unsigned char*, allocated with new[]. But auto_ptr only calls delete and not delete[], so i can't use it. I also need to have a function which creates and returns the array. I came out with my own implementation within a class ArrayDeleter, which i use like in this example: #include <Utils/ArrayDeleter.hxx> typedef Utils::ArrayDeleter<unsigned char> Bytes; void f() { // Create array with new unsigned char* xBytes = new unsigned char[10]; // pass array to constructor of ArrayDeleter and // wrap it into auto_ptr return std::auto_ptr<Bytes>(new Bytes(xBytes)); } ... // usage of return value { auto_ptr<Bytes> xBytes(f()); }// unsigned char* is destroyed with delete[] in destructor of ArrayDeleter Is there a more elegant way to solve this? (Even using another "popular" library)

• Absolute link to PDF - Executable File?

  - by tony noriega

  We have a mass emailing tool (.net based) that we developed in house. html editor. and sends via html and text formats. within the body we have an absolute URL path to a PDF on our server. some of our subscribers are stating that when they click on the link they get a message box that the file is an executable file and whether they should run it or not... why would that happen... and only to a certain group?

• SSRS mysterious extra pages

  I have two reports that are setup with the same page dimensions- A4 portrait, with page margins of 1cm. When I run the reports seperately and print them they both come out as expected: fitting into the width constraint of the page. However, when I include one report as a subreport in the other and then run and print the "master" report I start to experience problems. Even though both reports appear I get extra blank pages appearing every other page in the output. I'm sure I'm missing a simple trick - probably with the page sizes of the two reports but I can't figure it out - any pointers? I don't mind changing the setup of the subreport as it will never be run as a seperate eport in the wild, I only included that step to prove that it did indeed fit within the page!

• Objective C: Why is this code leaking?

  - by Johnny Grass

  I'm trying to implement a method similar to what mytunescontroller uses to check if it has been added to the app's login items. This code compiles without warnings but if I run the leaks performance tool I get the following leaks: Leaked Object # Address Size Responsible Library Responsible Frame NSURL 7 < multiple > 448 LaunchServices LSSharedFileListItemGetFSRef NSCFString 6 < multiple > 432 LaunchServices LSSharedFileListItemGetFSRef Here is the responsible culprit: - (BOOL)isAppStartingOnLogin { LSSharedFileListRef loginListRef = LSSharedFileListCreate(NULL, kLSSharedFileListSessionLoginItems, NULL); if (loginListRef) { NSArray *loginItemsArray = (NSArray *)LSSharedFileListCopySnapshot(loginListRef, NULL); NSURL *itemURL; for (id itemRef in loginItemsArray) { if (LSSharedFileListItemResolve((LSSharedFileListItemRef)itemRef, 0, (CFURLRef *) &itemURL, NULL) == noErr) { if ([[itemURL path] hasPrefix:[[NSBundle mainBundle] bundlePath]]) { [loginItemsArray release]; CFRelease(loginListRef); return YES; } } } [loginItemsArray release]; CFRelease(loginListRef); } return NO; }

• Newbie question about file formatting in Python

  - by user568041

  I'm writing a simple program in Python 2.7 using pycURL library to submit file contents to pastebin. Here's the code of the program: #!/usr/bin/env python2 import pycurl, os def send(file): print "Sending file to pastebin...." curl = pycurl.Curl() curl.setopt(pycurl.URL, "http://pastebin.com/api_public.php") curl.setopt(pycurl.POST, True) curl.setopt(pycurl.POSTFIELDS, "paste_code=%s" % file) curl.setopt(pycurl.NOPROGRESS, True) curl.perform() def main(): content = raw_input("Provide the FULL path to the file: ") open = file(content, 'r') send(open.readlines()) return 0 main() The output pastebin looks like standard Python list: ['string\n', 'line of text\n', ...] etc. Is there any way I could format it so it looks better and it's actually human-readable? Also, I would be very happy if someone could tell me how to use multiple data inputs in POSTFIELDS. Pastebin API uses paste_code as its main data input, but it can use optional things like paste_name that sets the name of the upload or paste_private that sets it private.

• Building 16 bit os - character array not working

  - by brainbarshan

  Hi. I am building a 16 bit operating system. But character array does not seem to work. Here is my example kernel code: asm(".code16gcc\n"); void putchar(char); int main() { char *str = "hello"; putchar('A'); if(str[0]== 'h') putchar('h'); return 0; } void putchar(char val) { asm("movb %0, %%al\n" "movb $0x0E, %%ah\n" "int $0x10\n" : :"m"(val) ) ; } It prints: A that means putchar function is working properly but if(str[0]== 'h') putchar('h'); is not working. I am compiling it by: gcc -fno-toplevel-reorder -nostdinc -fno-builtin -I./include -c -o ./bin/kernel.o ./source/kernel.c ld -Ttext=0x9000 -o ./bin/kernel.bin ./bin/kernel.o -e 0x0 What should I do?

• Generate "Finder.h" for a SIMBL plugin

  - by user1204395

  I'm trying to create a SIMBL plugin for Finder to add icon overlay over some files. I have this code: @implementation NSObject (FAIconOverlay) - (void)FAIconOverlay_TIconAndTextCell_drawIconWithFrame:(struct CGRect)arg1 { [self FAIconOverlay_TIconAndTextCell_drawIconWithFrame:arg1]; if (![self respondsToSelector:@selector(node)]) { return; } NSLog(@"%@", [[[NSClassFromString(@"FINode") nodeWithFENode:[(TNodeIconAndNameCell *)self node]] fullPath] lastPathComponent]); // Draw the icon overlay } - (void)FAIconOverlay_TDesktopIcon_drawIconInContext:(struct CGContext *)arg1 { [self FAIconOverlay_TDesktopIcon_drawIconInContext:arg1]; } @end I can draw the icon overlay but, when I try to get the path of the file I get a "Use of undeclared identifier TNodeIconAndNameCell". Looking this link < How to Write OS X Finder plugin I see that is neccessary to generate a Finder.h file... My question is: How to generate this file?? I tried running "class-dump -H Finder.app" but I get too more compiling errors Thank you very much!

• Hibernate / MySQL Bulk insert problem

  - by Marty Pitt

  I'm having trouble getting Hibernate to perform a bulk insert on MySQL. I'm using Hibernate 3.3 and MySQL 5.1 At a high level, this is what's happening: @Transactional public Set<Long> doUpdate(Project project, IRepository externalSource) { List<IEntity> entities = externalSource.loadEntites(); buildEntities(entities, project); persistEntities(project); } public void persistEntities(Project project) { projectDAO.update(project); } This results in n log entries (1 for every row) as follows: Hibernate: insert into ProjectEntity (name, parent_id, path, project_id, state, type) values (?, ?, ?, ?, ?, ?) I'd like to see this get batched, so the update is more performant. It's possible that this routine could result in tens-of-thousands of rows generated, and a db trip per row is a killer. Why isn't this getting batched? (It's my understanding that batch inserts are supposed to be default where appropriate by hibernate).

• How to inline string.h function on linux?

  - by tz1

  I want to optimize some code such that all the functions in string.h will be inlined. I'm on x86_64. I've tried -O3, -minline-all-stringops and when I do "nm a.out" it shows it is calling the glibc version. Checking with gcc -S, I see the calls. What am I missing? There are dozens of #ifdef _SOME_SETTING_ in string.h, and bits/string3.h shows the inline version, but I don't know how to get there. for example: $ cat test.c include main() { char *a, b; strcpy(b,a); } / When compiled with: gcc -minline-all-stringops -O6 -I. -S -o test.S test.c .file "test.c" .text .p2align 4,,15 .globl main .type main, @function main: .LFB12: .cfi_startproc subq $8, %rsp .cfi_def_cfa_offset 16 xorl %esi, %esi xorl %edi, %edi call strcpy addq $8, %rsp .cfi_def_cfa_offset 8 ret .cfi_endproc .LFE12: .size main, .-main .ident "GCC: (GNU) 4.5.1 20100924 (Red Hat 4.5.1-4)" .section .note.GNU-stack,"",@progbits */

• Training new employees on undocumented code

  - by glowcoder

  Our company has a large codebase (2500+ classes/interfaces in just the core alone, many more in other projects) for our flagship software product. We've never really hired more than one developer at a time, so we don't have a real training process. We're going to be bringing in 2-5 more developers now, and probably more in the near future (to put things into perspective, we have 7 right now.) Obviously, we would like to get these guys up to speed as soon as possible. The catch - almost all of our classes (95%+) are completely undocumented. No javadoc, no design docs, basically completely undocumented. What strategies can we employ to bring the new developers up to speed? I'd like to consider situations that include the existing code getting documented, but it's possible management won't allow for the time to get that done, so I also must consider situations where that won't happen. Has anyone been there before? What worked well for you? Thanks!

• Javascript code in ASP.NET MVC Partial Views (ASCX) or not?

  - by Alex

  Is there a "best practice" for placing Javascript code when you have many partial views and JS code that's specific to them? I feel like I'm creating a maintenance nightmare by having many partial views and then a bunch of independent Javascript files for them which need to be synced up when there is a partial view change. It appears, for maintenance purposes, better to me to put the JS code with the partial view. But then I'm violating generally accepted practices that all JS code should be at the bottom of the page and not mixed in, and also I'd end up with multiple references to the same JS file (as I'd include a reference in each ASCX for intellisense purposes). Does anyone have a better idea? Thank you!

• 'SHA1' is deprecated: first deprecated in OS X 10.7?

  - by sukhvir

  So I was trying to compile a code which has a SHA1 function .. I included following header: #include <openssl/sha.h> And I got the following error while compiling: test.c:9:5: error: 'SHA1' is deprecated: first deprecated in OS X 10.7 [-Werror,-Wdeprecated-declarations] SHA1(msg, strlen(msg), hs); ^ But man pages still have the descriptions for that function. Can anyone suggest any other header for a similar function ( MD5 or SHA1 )? PS - also do I need to link any libraries while compiling using gcc?

• Maven. What to do with "homeless" jars?

  - by Jake

  I have some proprietary.jar that I need to include in my project, but I don't wish to install it to the local repository. What I did initially was to put the jar into version control in my project's lib/ folder, and then specify the Maven dependency as: <!-- LOCAL DEPENDENCY --> <dependency> <groupId>topsecret</groupId> <artifactId>proprietary</artifactId> <version>0.0.1</version> <scope>system</scope> <systemPath>${basedir}/lib/java/proprietary.jar</systemPath> </dependency> However, this becomes a big problem when my project becomes someone else's dependency. Maven will not be able to validate this POM because the path is not absolute. What is the best way to overcome this problem?

• tutorials/books to create a plugin/module/library?

  - by fayer

  i wonder if there are tutorials/books explaining how you create a library/plugin/module for other to implement? libraries/frameworks like solr, doctrine, codeigniter etc. cause it seems that they follow the same pattern. having one "bootstrap" file to load configurations, other classes and so on. i aim to understand the basics, so i can create a such library. cause at the moment i want to code an address book that other can use. just include a bootstrap file and they are ready to use my classes (like Doctrine). recommendations of sources to learn these things of stuff? you experienced guys, how did you learn it? thanks.

• How to concatenate multiple lines of log file into single variable in batch file?

  - by psych

  I have a log file containing a stack trace split over a number of lines. I need to read this file into a batch file and remove all of the lines breaks. As a first step, I tried this: if exist "%log_dir%\Log.log" ( for /F "tokens=*" %%a in ("%log_dir%\Log.log") do @echo %%a ) My expectation was that this would echo out each line of the log file. I was then planning to concatenate these lines together and set that value in a variable. However, this code doesn't do what I would expect. I have tried changing the value of the options for delims and tokens, but the only output I can get is the absolute path to the log file and nothing from the contents of this file. How can I set a variable to be equal to the lines of text in a file with the line breaks removed?

• What is the most efficient way to list all of the files in a directory (including sub-directories)?

  - by prometheus

  I am writing a servlet which will examine a directory on the server (external to the web container), and recursively search for certain files (by certain files, I mean files that are of a certain extension as well as a certain naming convention). Once these files are found, the servlet responds with a long list of all of the found files (including the full path to the files). My problem is that there are so many files and directories that my servlet goes extremely slow. I was wondering if there was a best practice or existing servlet for this type of problem? Would it be more efficient to simply compile the entire list of files and do the filtering via js/jquery on the client side?

• Php code not executing - dies out when trying to refer to member of static class - no error displaye

  - by Ali

  I'm having some problems with this piece of code. I've included a class declaration and trying to create an object of that class but my code dies out. It doesn't seem to be an include issue as all the files are being included even the files called for inclusion within the class file itself. However the object is not created - I tried to put an echo statement in the __construct function but nothing it just doesn't run infact doesn't create the object and the code won't continue from there - plus no error is reported or displayed and I have error reporting set to E_ALL and display errors set to true WHats happening here :( =============EDIT SOrry I checked again the error is prior to teh object creation thing - it dies out when it tries to refer to a constant in a static class like so: $v = Zend_Oauth::REQUEST_SCHEME_HEADER; THis is the class or part of it - it has largely static functions its the Zend Oauth class: class Zend_Oauth { const REQUEST_SCHEME_HEADER = 'header'; const REQUEST_SCHEME_POSTBODY = 'postbody'; const REQUEST_SCHEME_QUERYSTRING = 'querystring'; // continued LIke I said no error is being reported at all :(

• mysql multiple where and inner join query combination

  - by bandhunt

  I'm a little lost as how to run two mysql queries as one(return one result set to be sorted etc). I understand how to do multiple JOINS but need to combine the below which is more than just a multiple join - it would include a multiple where etc. 1st query sql = "SELECT s.id, s.song_name FROM `songs` as s INNER JOIN `artists` as a ON s.artist_id = a.id WHERE ((`a`.id = #{search}))" 2nd query sql = "SELECT s.id, s.song_name FROM `songs` as s INNER JOIN `similarments` as si ON s.artist_id = si.artist_id WHERE ((`si`.similar_id = #{search}))" And then run both queries at once so I can ORDER them etc. Or combine them as one big query (maybe put an OR somewhere)? Thanks!

• Define a class dynamically?

  - by Pekka

  Is there a way to dynamically and conditionally create a class definition in PHP, i.e. if (condition matches) include file containing class definition else class myclass extends ancestor_class { .................... } without eval()? My background is the accepted answer to this question. I am looking for the best way to build a untouchable core library, with user-defined empty classes extending the core library if necessary. I want to create the final class definition "on the fly" if there is no user-defined empty class for a certain ancestor class.
