  • Outputting variable values in x86?

    - by Airjoe
    Hello All- I'm working on a homework assignment in x86 and it isn't working as I expect (surprise surprise!). I'd like to be able to output values of variables in x86 functions to ensure that the values are what I expect them to be. Is there a simple way to do this, or is it very complex? For what it's worth, the x86 functions are being used by a C file and compiled with gcc, so if that makes it simpler that is how I'm going about it. Thanks for the help.

  • JSF 2.0 Problem (faces-config)

    - by Sarang
    Hello everybody, We have faces-config.xml in JSF 1.0 where we entry about managed-beans, dependencies & navigations etc. I was developing a sample project using JSF 2.0. But, as I don't know annotation, I need to include face-config.xml externally. Please, provide the solution for it, as in JSF 2.0 we don't need to include it. What is reason behind it ? How do we set a bean as managed-bean. What is annotation ? How is it used ? Thanking you.

  • Did Delphi ever get a for each loop?

    - by Ryan
    Hello, I've read that Delphi was supposed to get a for each loop in Delphi 9. Did this functionality ever make it into the language? My Delphi 2009 IDE doesn't seem to recognize the for each syntax. Here's my code: procedure ProcessDirectory(p_Directory, p_Output : string); var files : TStringList; filePath : string; begin files := GetSubfiles(p_Directory); try for (filePath in files.Strings) do begin // do something end; finally files.Free; end; end;

  • How do I write my own desktop sharing application in java ?

    - by nomemory
    Hello I want write my own desktop sharing application in Java. The application should have some very default features: Capture screen; Allow a remote connected user to click / edit fields. I was thinking to use Java Robot class for mouse movements / key pressing. The problem is i don't know what screen capture strategy to use. Should I make sequentially screen captures (on the hosting computer) every second, and send those captures with UDP via network, so that the clients can intercept the data-grams ? Isn't this a little overkill for the network ? What other strategies are available ? (Except trying an already existing app). PS: If necessary I can even write native code using JNI (still that's the last thing I planning to do).

  • Out-Of-Memory while doing Core Data migration

    - by Kamchatka
    Hello, I'm migrating a CoreData model between two versions of an application. I was storing binary data as blobs in the previous version and I want to take them out of the blobs for performance. My issue is that during the migration it seems that Core Data loads everything into memory which leads to Low Memory Warnings and then to my app being killed. Apple documentation suggests the following : http://developer.apple.com/library/mac/documentation/Cocoa/Conceptual/CoreDataVersioning/Articles/vmCustomizingTheProcess.html#//apple_ref/doc/uid/TP40005510-SW9 However, it seems to rely on the fact that the large objects are applied different mapping. In my case, all the objects are basically the same and the same mapping has to be applied to each of them. I don't see in this case how I could apply their technique. How should I handle a migration with very large objects ?

  • Class variable defined at @implementation rather than @interface?

    - by bitcruncher
    Hello. I'm new to Objective-C, but I am curious about something that I haven't really seen addressed anywhere else. Could anyone tell me what is the difference between a private variable that is declared at the @interface block versus a variable that is declared within the @implementation block outside of the class methods, i.e: @interface Someclass : NSObject { NSString *forExample; } @end vs. @implementation Someclass NSString *anotherExample; -(void)methodsAndSuch {} @end It seems both variables ( forExample, anotherExample ) are equally accessible throughout the class and I can't really find a difference in their behaviour. Is the second form also called an instance variable?

    Hello, The title says it all, really. I'm trying to get an array of (9) numbers squared then printed but I keep coming back with only one result - the number of numbers in the array squared- obviously not what I want. Thanks for any help. Ok, here is my terrible code so far.

  • Where to start with C#

    - by RobertPitt
    Hello fellow programmers. Im a pretty experienced programmer in PHP and mainly web languages but today i have decided i want to start to learn a new language! Im only 21 and I feel as I will never make it in the programming industry without a great set of languages under my belt, So i decided to have a look at C#. The reason I have chosen C# is because some C programmers have told me that C# is the best language to learn for desktop applications. I think i need to get started with the Syntax / Structure of C#, What Development Environment to use, and other things that i might face along my new journey. I hope somebody can guide me Thanks.

  • How to detect when UITextField become empty

    - by Jakub
    Hello, I would like to perform a certain action when UITextField becomes empty (user deletes everything one sign after another or uses the clear option). I thought about using two methods - (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string; and - (BOOL)textFieldShouldClear:(UITextField *)textField; from UITextFieldDelegate I'm not sure how to detect the situation when the text field becomes empty? I tried with: if ([textField.text length] == 0) but it does't work as the fisrt of the above methods is called before the sign is deleted from the text field. Any ideas?

  • How to get top 3 frequencies in MySQL?

    - by Amenhotep
    Hello, In MySQL I have a table called "meanings" with three columns: "person" (int), "word" (byte, 16 possible values) "meaning" (byte, 26 possible values). A person assigns one or more meanings to each word: person word meaning ------------------- 1 1 4 1 2 19 1 2 7 <-- second meaning for word 2 1 3 5 ... 1 16 2 Then another person, and so on. There will be thousands of persons. I need to find for each of the 16 words the top three meanings (with their frequencies). Something like: word 1: meaning 5 (35% of people), meaning 19 (22% of people), meaning 2 (13% of people) word 2: meaning 8 (57%), meaning 1 (18%), meaning 22 (7%) ... Is it possible to solve this with a single MySQL query? (If this problem is a classic one and has been answered elsewhere, I would appreciate if you could give me a link to the solution.) Thank you very much, ve

    Hello, I am interested in writing an email sniffer that saves all emails sent via web based clients to hd, but I can't work out how to do this. How can I catch HTTPS mail before it is encrypted? I would really appriciate some useful info. I cannot find anything information on the web. There's a program called HTTP Analyzer V5 that does the exact thing I want to make. How should I start? If I make a packet sniffer, it's useless because all data is encrypted. Is there any other option?

  • A specific string format with a number and character together represeting a certain item

    - by sil3nt
    Hello there, I have a string which looks like this "a 3e,6s,1d,3g,22r,7c 3g,5r,9c 19.3", how do I go through it and extract the integers and assign them to its corresponding letter variable?. (i have integer variables d,r,e,g,s and c). The first letter in the string represents a function, "3e,6s,1d,3g,22r,7c" and "3g,5r,9c" are two separate containers . And the last decimal value represents a number which needs to be broken down into those variable numbers. my problem is extracting those integers with the letters after it and assigning them into there corresponding letter. and any number with a negative sign or a space in between the number and the letter is invalid. How on earth do i do this?

  • PayPal IPN & ASP.NET MVC

    - by Wayne
    Hello - I have a strange problem that somebody can hopefully help me with. For a while now I have been using PayPal's IPN service for our website. In order to test it I have a port opened up on our firewall pointing to my machine. This has been working great with no problems at all. I recently upgraded to the RTM release of ASP.NET MVC and now things are not working. I can navigate to my IPN handler from the outside world so I know it's not my connection or a firewall issue. It simply refuses to recieve any PayPal IPN messages. I am puzzled why the page can be accessed yet the PayPal IPN server wont connect to it. I realize there could be a 1000 different reasons for this, but I am hoping somebody out there can point me in the right direction!

  • Sharing user controls acrros multiple websites

    - by Jasper
    Hello, I am currently working on a project which involves three different websites with a lot of common functionality. At the moment the common functionality is placed in a different website full of user controls. The problem is sharing the user controls across the multiple websites. Looking around on SO and other websites, the only solution seems the be using virtual directories. As this is a workable solution (we us this at the moment) it doesn't seem as a "clean" solution. Which "best practices" exist on sharing common functionality (including the GUI/HTML) between different site? Is it (for example) possible to create a single Web Application project and deploy subdirectories (each with their own web.config) to different production environments?

    Hello, I am totally a novice in Multi-Core Programming, but I do know how to program C++. Now, I am looking around for Multi-Core Programming library. I just want to give it a try, just for fun, and right now, I found 3 APIs, but I am not sure which one should I stick with. Right now, I see Boost's MPI, OpenMP and TBB. For anyone who have experienced with any of these 3 API (or any other API), could you please tell me the difference between these? Are there any factor to consider, like AMD or Intel architecture?

  • Wordpress: Sort posts by meta value after AFTER querying from database

    - by Joseph Carrington
    Hello, I am pulling posts from my database by using Wordpress' WP_Query object like so: $shows_query = new WP_Query("category_name=shows&meta_key=band&meta_value=$artist_id"); I have another meta value I would like to sort the posts by, however. The meta key is 'date'. The WP_Query object can no work with multiple meta_keys, so this does not work: $shows_query = new WP_Query("category_name=shows&meta_key=band&meta_value=$artist_id&meta_key=date&orderby=meta_value&order=DESC"); So now I have to figure out a way to sort the posts in $shows_query['posts'] by one of their meta_values, which are not even IN their array. Any other, more sensible approach would also be appreciated.

  • T-SQL: How to use GROUP BY and getting the value which excesses 60%?

    - by Torben H.
    Hello, sorry for the bad title, I don't know how to describe my problem. I have the following table: | ItemID | Date | ------------------------- | 1 | 01.01.10 | | 1 | 03.01.10 | | 1 | 05.01.10 | | 1 | 06.01.10 | | 1 | 10.01.10 | | 2 | 05.01.10 | | 2 | 10.01.10 | | 2 | 20.01.10 | Now I want to GROUP BY ItemID and for the date I want to get the value, which excesses 60%. What I mean is, that for item 1 I've five rows, so each have a percentage of 20% and for item 2 I've three row, so each have a percentage of 33,33%. So for item 1 I need the 3rd and for item 2 the 2nd value, so that the result looks like that. | ItemID | Date | ------------------------- | 1 | 06.01.10 | | 2 | 10.01.10 | Is there a easy way so get this data? Maybe using OVER? Thank you Torben

  • Fibonacci using SBN in OISC in Machine Language

    - by velociraptor
    Hello, I want to generate fibonacci series using SBN in an OISC architecture. My initial approach is to implement it in assembly language first and then convert it to machine language. The first steps involve storing 0 and 1 in 2 registers and then subtract 1 from 0 and repeatedly subtract 1 in the consequent steps. Everytime it will generate a negative number and since its negative, it branches off and fetches the absolute value finding instruction. Is my approach correct? My confusion in the meaning of OISC. Correct me if i'm wrong, if i perform a subtraction and then an absolute value finding, it means that that i'm using 2 instructions everytime. or is it that in the OISC processor both these instructions are done at the sametime which would mean that my approach is correct. Please help. thank you all
