  • What does subl do here?

    - by drozzy
    So... I'm compiling into assembler, with gcc -S -O2 -m32: void h(int y){int x; x=y+1; f(y); f(2); } And it gives me the following: .file "sample.c" .text .p2align 4,,15 .globl h .type h, @function h: pushl %ebp movl %esp, %ebp subl $24, %esp movl 8(%ebp), %eax movl %eax, (%esp) call f movl $2, 8(%ebp) leave jmp f .size h, .-h .ident "GCC: (GNU) 4.4.3 20100127 (Red Hat 4.4.3-4)" .section .note.GNU-stack,"",@progbits Now I know what pushl and movel: they store the current frame pointer onto the stack and then set the value of the frame pointer register to the value of the Stack Pointer. But I have no idea what the subl $24, %esp is. Thanks!

  • How do I add artwork to an iTunes track with obj-c AppScript?

    - by demonslayer319
    aTrack is an ITReference* object, value is an NSImage* object, initialized via a URL to a jpeg. [[[[[aTrack artworks] data_] set] to:value] send]; I get the following message in GDB: 2010-03-09 16:59:42.860 Sandbox[2260:a0f] Can't pack object of class NSImage (unsupported type): <NSImage 0x10054a440 Size={0, 0} Reps=( I then tried the following code: NSData *imageData = [[NSData alloc] initWithData:[value TIFFRepresentation]]; [[[[[aTrack artworks] data_] set] to:imageData] send]; and get this message instead 2010-03-09 16:46:09.341 Sandbox[2193:a0f] Can't pack object of class NSConcreteData (unsupported type): <4d4d002a 00000000> In the AppScript documentation, it says that the "data" property of the "artwork" item is a PICTPicture image. How do I convert an NSImage to a PICT? Am I using the AppScript all wrong?

  • What happens when Npgsql connection pool reaches Max

    - by ClearCarbon
    Both the name of the connection string parameter and this blog post - http://fxjr.blogspot.co.uk/2010/04/npgsql-connection-pool-explained.html - lead me to believe that Npgsql wont exceed the MaxPoolSize value set in the connection string. However the docs (http://npgsql.projects.postgresql.org/docs/manual/UserManual.html) say "Max size of connection pool. Pooled connections will be disposed of when returned to the pool if the pool contains more than this number of connections. Default: 20" This suggests that the pool can actually grow larger than MaxPoolSize and it is in fact just a level at which Npgsql starts to aggressively remove connections from the pool as soon as they are returned. I've been searching to try and find an answer but I can find out exactly what happens when you reach MaxPoolSize. Anyone else know? edit: I should add we are using Npgsql 2.0.6.0 due to another dependency being supported only up to that version.

  • Having difficulty add a custom icon to a JFrame

    - by Oliver
    Hi, I have been trying to change the icon in the frame. I have virtually tried everything: The icon is 16x16 which is the right size ....doesn't work I've trying PNG,GIF and JPG formats none of them work. Tried different way of setting the icon....doesn't work. I've tried relative (local paths) e.g. "icon.gif" and absolute paths e.g. "c:\work\java\icon.gif" ...doesn't work Here is my code and see if you can figure it out Thanks Oli import javax.swing.*; public class androidDriver { public static void main(String[] args) throws IOException { JFrame f = new JFrame("Android Data Viewer"); f.setResizable(false); f.setSize(300,300); f.setLocationRelativeTo(null); f.setVisible(true); f.setIconImage(new ImageIcon("androidIcon2.gif").getImage()); } }

  • Packing a file into an ELF executable

    - by Pierre Bourdon
    Hello, I'm currently looking for a way to add data to an already compiled ELF executable, i.e. embedding a file into the executable without recompiling it. I could easily do that by using cat myexe mydata > myexe_with_mydata, but I couldn't access the data from the executable because I don't know the size of the original executable. Does anyone have an idea of how I could implement this ? I thought of adding a section to the executable or using a special marker (0xBADBEEFC0FFEE for example) to detect the beginning of the data in the executable, but I do not know if there is a more beautiful way to do it. Thanks in advance.

  • How can I set the class for a <dt> element in a Zend_Form?

    - by Mallika Iyer
    I'm trying to set the width of the style for a group of < dt elements in a Zend_Form. Is there a way to set a class for a dt element, so the end result would be something like this: <dt id="name-label" class="xyz" > // trying to add the 'class="xyz" <label class="required" for="name">Name:</label> </dt> <dd id="name-element"> <input type="text" maxlength="255" size="30" value="" id="name" name="name"> </dd>

  • While loop in IL - why stloc.0 and ldloc.0?

    - by Michael Stum
    I'm trying to understand how a while loop looks in IL. I have written this C# function: static void Brackets() { while (memory[pointer] > 0) { // Snipped body of the while loop, as it's not important } } The IL looks like this: .method private hidebysig static void Brackets() cil managed { // Code size 37 (0x25) .maxstack 2 .locals init ([0] bool CS$4$0000) IL_0000: nop IL_0001: br.s IL_0012 IL_0003: nop // Snipped body of the while loop, as it's not important IL_0011: nop IL_0012: ldsfld uint8[] BFHelloWorldCSharp.Program::memory IL_0017: ldsfld int16 BFHelloWorldCSharp.Program::pointer IL_001c: ldelem.u1 IL_001d: ldc.i4.0 IL_001e: cgt IL_0020: stloc.0 IL_0021: ldloc.0 IL_0022: brtrue.s IL_0003 IL_0024: ret } // end of method Program::Brackets For the most part this is really simple, except for the part after cgt. What I don't understand is the local [0] and the stloc.0/ldloc.0. As far as I see it, cgt pushes the result to the stack, stloc.0 gets the result from the stack into the local variable, ldloc.0 pushes the result to the stack again and brtrue.s reads from the stack. What is the purpose of doing this? Couldn't this be shortened to just cgt followed by brtrue.s?

  • Revision Materals, other than book, for MCTS 70-536 Exam

    - by Damien
    Does anyone have any recommendations on revision materials for the MCTS 70-536 exam other than the monstrosity that is the official book? I am finding it very difficult to absorb the amount of information in the book in such a passive way (i.e just reading) it's not going in. My current approach has been to use the practise tests and make notes on the questions I was unsure about but given the wide varity of questions that could come up I am not sure if this is the correct way to do things. So is there someone with more condensed, bite-size, information to take in. Maybe videos or podcasts? Cheers!

  • glibc backtrace - can't redirect output to file

    - by Jason Antman
    Hi, I'm in the process of debugging a C program (that I didn't write). I have all of the internal debugging tools (a whole bunch of printf's) enabled, and I wrote a small PHP script that uses proc_open() and just grabs both stdout and stderr, and time-coordinates them in one file. At the moment, the binary is dieing with a realloc() error that's caught by glibc, and a glibc backtrace is printed, beginning with: *** glibc detected *** /sbin/rsyslogd: realloc(): invalid next size: 0x00002ace626ac910 *** Here's the thing I don't understand: I've confirmed that the PHP script is catching both stdout and stderr from the binary's process and writing them to the correct files, but this backtrace is still printed to the console. Where is this coming from? Is there some magical output channel other than stdout and stderr? Any ideas on how I go about capturing this backtrace to a file, or sending it out with stderr? Thanks, Jason

  • MFMailComposerViewController doesn't always display attachments

    - by davbryn
    I'm attaching a few files to an email to export from the application I've written, namely a .pdf and a .png. I create these by rendering some view to a context and creating an image and a pdf. I can validate that the files are created properly (I can confirm this by looking in my apps sandbox from Finder, and also by sending the email. I receive the files correctly.) The problem I'm getting is that larger files don't have a preview generated for them within the MFMailComposerViewController view (I simply get a blue icon with a question mark). Is there a limitation on file sizes that can be attached in order for preview to function correctly? With small files it works as expected, but if I try and attach a pdf with the following properties: Pages: 1 Dimensions: 2414 x 1452 Size: 307 KB the file is generated correctly, but displays the question mark icon. If there is no way around that, can I remove the attachment preview altogether? Many thanks, Bryn

  • Java anonymous class efficiency implications

    - by Po
    Is there any difference in efficiency (e.g. execution time, code size, etc.) between these two ways of doing things? Below are contrived examples that create objects and do nothing, but my actual scenarios may be creating new Threads, Listeners, etc. Assume the following pieces of code happen in a loop so that it might make a difference. Using anonymous objects: void doSomething() { for (/* Assume some loop */) { final Object obj1, obj2; // some free variables IWorker anonymousWorker = new IWorker() { doWork() { // do things that refer to obj1 and obj2 } }; } } Defining a class first: void doSomething() { for (/* Assume some loop */) { Object obj1, obj2; IWorker worker = new Worker(obj1, obj2); } } static class Worker implements IWorker { private Object obj1, obj2; public CustomObject(Object obj1, Object obj2) {/* blah blah */} @Override public void doWork() {} }; Thank you :)

  • problem in adding data to an array in Objective-C!!!

    - by anurag
    I am grappling with adding an NSData object to a NSMutable array. The code is executing fine but it is not adding the objects in the array.The code is as follows: NSData * imageData = UIImageJPEGRepresentation(img, 1.0); int i=0; do{ if([[tempArray objectAtIndex:i] isEqual:imageData]) { [tempArray removeObjectAtIndex:i]; } else { [tempArray addObject:imageData]; //NSLog(@"ANURAG %@",[tempArray objectAtIndex:0]); } }while(i<[tempArray count]) ; The NSLog statement shows the object added is null however the value of imageData is not null. I have defined the tempArray as a static memeber of the class in which this code is written. Is it because of the size of the data object as it is the data of an image????

  • Garbage collection of Strings returned from C# method calls in ascx pages

    - by Icarus
    Hi, For a web application developed on ASP.NET, we are finding that for user control files (ascx) we are returning long strings as a result of method calls. These are embedded in the ascx pages using the special tags <% %> When performing memory dump analysis for the application, we find that many of those strings are not being garbage collected. Also, the ascx pages are compiled to temporary DLLs and they are held in memory. Is this responsible for causing the long strings to remain in memory and not be garbage collected ? Note : The strings are larger than 85K in size.

  • How to properly update a feature branch from trunk?

    - by Pavel Radzivilovsky
    SVN book says: ...Another way of thinking about this pattern is that your weekly sync of trunk to branch is analogous to running svn update in a working copy, while the final merge step is analogous to running svn commit from a working copy I find this approach very unpractical in large developments, for several reasons, mostly related to reintegration step. From SVN v1.5, merging is done rev-by-rev. Cherry-picking the areas to be merged would cause us to resolve the trunk-branch conflicts twice (one when merging trunk revisions to the FB, and once more when merging back). Repository size: trunk changes might be significant for a large code base, and copying the differences files (unlike SVN copy) from trunk elsewhere may be a significant overhead. Instead, we do what we call "re-branching". In this case, when a significant chunk of trunk changes is needed, a new feature branch is opened from current trunk, and the merge is always downward (Feature branches - trunk - stable branches). This does not go along SVN book guidelines and developers see it as extra pain. How do you handle this situation?

  • How to use jasper reports to print something only on the first page ?

    - by Harsha
    How to use jasper reports to print something only on the first page. I am using jasper reports for printing invoices and only on the 1st page I need to print the Remit Payment To section with the address following it. Customer address is also present there. The way it is currently designed is that this goes into pageFooter section and we use printWhenExpression(PAGE_NUMBER = 1) so that this only gets printed on the 1st page of the invoice. But the downside of this approach is that the jasper engine reserves the size equivalent of the page footer on all the other pages (1..n) of the invoice. So we are able to use only about 2/3 rd of all pages. Remaining 1/3rd page which is for page footer is blank for all pages except the 1st page. This increases the number of pages. Any ideas for fixing this issue?

  • Grabbing random object from ArrayList is not random.

    - by Isai
    I am creating a method where if you pass in a parameter of type Random, then it will return a random object. Here is basically what I am trying to do: public T choose(Random r) { int randomInt = r.nextInt(randomList.size()); // randomList is just a instance variable return randomList.get(randomInt); } The random list has this the following strings:[2, 2, 2, 1, 1, 1, 1, c, c, c, a, a, a, a] Then I made a driver with the following code for (int i = 0; i < 10; i++) { System.out.print(rndList.choose(rnd)); // rnd is initialized as a static Random variable } However my outputs are not coming out random. I used the debugger and found out that my choose method generates an integer that is relatively low, so it will always print out either 2's or 1's but never c's or a's. I can't figure out why this is happening and help would be greatly appreciated.

  • Why would it be a bad idea to have database connection open between client requests?

    - by AspOnMyNet
    1) Book I’m reading argues that connections shouldn’t be opened between client requests, since they are a finite resource. I realize that max pool size can quickly be reached and thus any further attempts to open a connection will be queued until connection becomes available and for that reason it would be imperative that we release connection as soon as possible. But assuming all request will open connection to the same DB, then I’m not sure how having a connection open between two client requests would be any less efficient than having each request first acquiring a connection from connection pool and later returning that object to connection pool? 2) Book also recommends that when database code is encapsulated in a dedicated data access class, then method M opening a database connection should also close that connection. a) I assume one reason why M should also close it, is because if method M opening the connection doesn’t also close it, but instead this connection object is used inside several methods, then it’s more likely that a programmer will forget to close it. b) Are there any other reasons why a method opening the connection should also close it? thanx

  • Do Blob properties on entities affect query performance?

    - by Jaroslav Záruba
    Hello I'm trying to make my mind on whether to store a binary representation of an entity as its Blob property, or whether I better keep the blobs in some separate 'wrapping' class. Possible impact on memory heap and/or a query execution time are my concerns in the first case, complexity votes against the other one. I know Blobs are not indexed, i.e. index size is not what I'm worrying about. Also I assume for blobs Datastore puts defaultFetchGroup to false, but does it mean that blobs don't make a difference in queries? Regards J. Záruba
