  • php slideshow sample

    - by serhio
    I try to do a simple image slideshow in php (just cycle images, no links, no other effects). after some googling I found the following in net: <HTML> <HEAD> <TITLE>Php Slideshow</TITLE> <script language="javascript"> var speed = 4000; // time picture is displayed var delay = 3; // time it takes to blend to the next picture x = new Array; var y = 0; <?php $tel=0; $tst='.jpg'; $p= "./images"; $d = dir($p); $first = NULL; while (false !== ($entry = $d->read())) { if (stristr ($entry, $tst)) { $entry = $d->path."/".$entry; print ("x[$tel]='$entry';\n"); if ($first == NULL) { $first = $entry; } $tel++; } } $d->close(); ?> function show() { document.all.pic.filters.blendTrans.Apply(); document.all.pic.src = x[y++]; document.all.pic.filters.blendTrans.Play(delay); if (y > x.length - 1) y = 0; } function timeF() { setTimeout(show, speed); } </script> </HEAD> <BODY > <!-- add html code here --> <?php print ("<IMG src='$first' id='pic' onload='timeF()' style='filter:blendTrans()' >"); ?> <!-- add html code here --> </BODY> </HTML> but it displays only the first image from the cycle. Do I something wrong? the resulting HTML page is: <HTML> <HEAD> <TITLE>Php Slideshow</TITLE> <script language="javascript"> var speed = 4000; // time picture is displayed var delay = 3; // time it takes to blend to the next picture x = new Array; var y = 0; x[0]='./images/under_construction.jpg'; x[1]='./images/BuildingBanner.jpg'; x[2]='./images/littleLift.jpg'; x[3]='./images/msfp_smbus1_01.jpg'; x[4]='./images/escalator.jpg'; function show() { document.all.pic.filters.blendTrans.Apply(); document.all.pic.src = x[y++]; document.all.pic.filters.blendTrans.Play(delay); if (y > x.length - 1) y = 0; } function timeF() { setTimeout(show, speed); } </script> </HEAD> <BODY > <!-- add html code here --> <IMG src='./images/under_construction.jpg' id='pic' onload='timeF()' style='filter:blendTrans()' ><!-- add html code here --> </BODY> </HTML>

  • Odd nested dictionary behavior in python

    - by adept
    Im new two python and am trying to grow a dictionary of dictionaries. I have done this in php and perl but python is behaving very differently. Im sure it makes sense to those more familiar with python. Here is my code: colnames = ['name','dob','id']; tablehashcopy = {}; tablehashcopy = dict.fromkeys(colnames,{}); tablehashcopy['name']['hi'] = 0; print(tablehashcopy); Output: {'dob': {'hi': 0}, 'name': {'hi': 0}, 'id': {'hi': 0}} The problem arises from the 2nd to last statement(i put the print in for convenience). I expected to find that one element has been added to the 'name' dictionary with the key 'hi' and the value 0. But this key,value pair has been added to EVERY sub-dictionary. Why? I have tested this on my ubuntu machine in both python 2.6 and python 3.1 the behaviour is the same.

  • Map only certain parts of the class to a database using SQLAlchemy?

    - by Az
    When mapping an object using SQLAlchemy, is there a way to only map certain elements of a class to a database, or does it have to be a 1:1 mapping? Example: class User(object): def __init__(self, name, username, password, year_of_birth): self.name = name self.username = username self.password = password self.year_of_birth = year_of_birth Say, for whatever reason, I only wish to map the name, username and password to the database and leave out the year_of_birth. Is that possible and will this create problems? Edit - 25/03/2010 Additionally, say I want to map username and year_of_birth to a separate database. Will this database and the one above still be connected (via username)?

  • Should I learn VB.NET or C#?

    - by Ravi
    Background I have decided to do my graduation project (yet to start) in .NET. Regarding it, I am bit confused about: what language should I learn: VB.NET or C#? What I have learnt from those who know it that both VB.NET and C# have: The same concepts VB.NET is simpler as it is more like English statements but also C# is simple too if you already know C (Which I do know) Question So considering some factors, e.g. career point of view, newness, challenging and beneficial, etc., what language should I choose? Please help me out. And clearly do justify your answer (whatever reason you have.) References (Extra) A little information about what project I am doing: It is a database file system. Technologies I'll be using are SQL Server, WPF, etc. I just love the concept of Database file system.So those who want to know more about Database file system, here are the links DBFS (This one is really good.Serves as primary reference for me) Towards A Single Folder Filesystem stackoverflow-What is a database file system? UPDATE1 : After some really good explained answers (actually all are good at their place), I have finally decided to go with C# for myself. Thank you all. Still, you are requested to put your opinion (Once it is reopened,of course) UPDATE2 : Question reopened and made community wiki.Thank you all.

  • SAP related testing

    - by mgj
    Dear all, One notion that has been prevalent mostly as rumours for many aspiring programmers is that the testing phase of the SDLC(Software Development Life Cycle) is not that challenging and interesting as one's job as a tester after a period of time becomes monotonous because a person does the same thing repeatedly over and over again. Thats why many have this complexion of looking for a developers job rather than that of testers. Don't testers have a space for themselves in software companies to grow..? Please feel free to express your views for or against this. How true is that, could you please give e.g.'s of instances( need not be practical, even theoretical would suffice) which actually contradict this statement wrt a tester's career specifically wrt the SAP domain. E.g.'s from other domains are also welcome. This question is not meant to hurt someone's feelings who is in the testing domain. Its just that for e.g. in my case I want to know what actually would be the challenge's a tester could also face in real life situations.Something that would make their job also interesting and fun-filled. I myself am pro-testing and also interested in pursuing testing as a profession in a sw co, just curious to know more about it so...:) Thanks..:)

  • How do I get an overview and a methodology for programming in Python

    - by Peter Nielsen
    I've started to learn Python and programming from scratch. I have not programmed before so it's a new experience. I do seem to grasp most of the concepts, from variables to definitions and modules. I still need to learn a lot more about what the different libraries and modules do and also I lack knowledge on OOP and classes in Python. I see people who just program in Python like that's all they have ever done and I am still just coming to grips with it. Is there a way, some tools, a logical methodology that would give me an overview or a good hold of how to handle programming problems ? For instance, I'm trying to create a parser which we need at the office . I also need to create a spider that would collect links from various websites. Is there a formidable way of studying the various modules to see what is needed ? Or is it just nose to the grind stone and understand what the documentation says ? Sorry for the lengthy question..

  • One Line 'If' or 'For'...

    - by aTory
    Every so often on here I see someone's code and what looks to be a 'one-liner', that being a one line statement that performs in the standard way a traditional 'if' statement or 'for' loop works. I've googled around and can't really find what kind of ones you can perform? Can anyone advise and preferably give some examples? For example, could I do this in one line: example = "example" if "exam" in example: print "yes!" Or: for a in someList: list.append(splitColon.split(a))

  • Windows disassembler: looking for a tool...

    - by SigTerm
    Hello. I'm looking for a (preferably free) tool that can produce "proper" disassembly listing from a (non-.NET) windows PE file (*.exe or *.dll). Important requirement: it should be possible to run the listing through a windows assembler (nasm, masm or whatever) and get working exe again (not necessarily identical to original one, but it should behave in the same way). Intended usage is adding new subroutines into existing code, when source is not available. Ideally, tool should be able to detect function/segment boundaries, API calls, and generate proper labels for jumps (I can live without labels for loops/jumps, though, but function boundary detection would be nice), and keep program resources/segments in place. I'm already aware of IdaPRO(not free), OllyDBG (useful for in-place hacking, doesn't generate disassembly listing, AFAIK), ndisasm (output isn't suitable for assembler), dumpbin (useful, but AFAIK, output isn't suitable for assembler) and "proxy dll" technique. Ideas? Or maybe there is a book/tutorial that explains some kind of alternative approach?

  • Easiest Java image processing solution

    - by Daniel Fath
    Here is the deal, in my Java project I have to make a composite document that combines both text and images; So I'm looking for a way to manipulate pictures (rotate, change size, that sort of thing). The API I'm looking for should be clear and easy to learn (preferably with some examples), it should cover the basic transformations I made above - rotate,change size, eventually crop.

  • How to use TDD in a not very "Testy" environment

    - by dbemerlin
    I work in a company where OOP is... well, not fobidden, but at least frowned upon as "too complex". My coworkers write lots of 100+ lines functions and they are usually all in a "funcs.inc.php" or "something.inc.php", if they use any functions at all, often they don't since copy-paste is faster. I would love to start using TDD at least for the code i write but as i have to interface with their code i can't see how to begin. It's not legacy code as they are actively developing it and i don't want to modify their code as i don't want to provoke conflicts. Which approach would you suggest, except for changing the company?

  • Advice needed from PHP/Cake PHP expert

    - by Hiro
    I'm very new to programming (besides SQL and databases), but I ultimately want to master Cake PHP for web development. Now, given how new I am, I'm rather lost as to how I get started. Down the road, I want to use MVC framework so that I help myself be disciplined in the way I build. However, I know basic knowledge of PHP and OOP PHP are required. So my question is this: what are the right steps to mastering Cake PHP? I don't want to skip critical phases of learning before learning to Cake PHP. At the same time, I don't want to spend more time than required learning PHP if I can learn it directly through Cake PHP knowledge. Any advice would be appreciated.

  • Getting a char array from a vector<int>?

    - by Legend
    I am trying to pass a value from C++ to TCL. As I cannot pass pointers without the use of some complicated modules, I was thinking of converting a vector to a char array and then passing this as a null terminated string (which is relatively easy). I have a vector as follows: 12, 32, 42, 84 which I want to convert into something like: "12 32 42 48" The approach I am thinking of is to use an iterator to iterate through the vector and then convert each integer into its string representation and then add it into a char array (which is dynamically created initially by passing the size of the vector). Is this the right way or is there a function that already does this?

  • What process does professional website building follow?

    - by Sivvy
    I've searched for a while, but I can't find anything related on Google or here. Me and some friends were debating starting a company, so I figure it might be good to do a quick pilot project to see how well we can work together. We have a designer who can do HTML, CSS and Flash, enjoys doing art, but doesn't like to do HTML and CSS... And 2 programmers that are willing to do anything. My question is, from an experienced site builder's perspective, what steps do we do - in chronological order - to properly handle a website? Does the designer design the look and feel of the site, then the programmers fill in the gaps with functionality? Or do the programmers create a "mock-up" of the site with most of the functionality, then the designer spices it up? Or is it more of a back-and-forth process? I just want to know how a professional normally handles it.

  • How to learn about Threads, Especially in Java.

    - by Javed Ahamed
    I have always been kind of confused by threads, and my class right now makes heavy use of them. We are using java.util.concurrent but I don't even really get the basics. UpDownLatch, Futures, Executors; these words just fly over my head. Can you guys suggest any resources to help learn what I need from the ground up? Thanks a lot in advance!

  • Using 'load' in octave

    - by lollygagger
    Is there a way to tell the load function to only load until a certain line? I want to read in a data file and assign the numbers to an array, however, I want it to stop after it has created a 200 X 200. Could I also do this with a do-while loop and fgetl? When I try to use fgetl(fid, len) and give it 'len', it does not obey :-/ How can I tell octave to ignore the comment lines in an input file? They are '#' characters, so I figured octave would just automatically ignore them, but not so... Thanks.

What am I doing wrong?
