  • How to change input button image using CSS?

    - by Baltimark
    So, I can create an input button with an image using <INPUT type="image" src="/images/Btn.PNG" value=""> But, I can't get the same behavior using CSS. for instance, i've tried <INPUT type="image" class="myButton" value=""> where "myButton" is defined in the css file as .myButton{ background:url(/images/Btn.PNG) no-repeat; cursor:pointer; width: 200px; height: 100px; border: none; } If that's all I wanted to do, I could use the original style, but I want to change the button's appearance on hover (using a myButton:hover class). I know the links are good because I've been able to load them for a background image for other parts of the page (just as a check). I found examples on the web of how to do it using javascript, but I'm looking for a css solution. I'm using Firefox 3.0.3 if that makes a difference. Thanks

  • how to combine changes tracked from several documents

    - by Jessica
    I tried to search the solution in internet, but found nothing, is there anyone who can help me? For my application, there is one document (Microsoft word), and this document is reviewed by several people in the "Track changes" mode, so the input to my application is the original document and the reviewed documents with changes (like insert/delete/comments). By this link , I know how to extract all the changes from the reviewed documents. what i want is to combine all the changes from all the reviewed documents into ONE document, and make all the changes "accepted", so the output of my application is one modified Microsoft document with all the changes (delete/insert/comment) accepted. My problem is that I don't know how to combine the changes from several documents into one single document. Anyone has an idea how to do this? Thank you very much in advance.

  • iPhone switching views without first view being reset

    - by user298261
    Heya! I'm making a role-playing game, and I want to have a Map View and a Battle Screen. With the possibility of other screens as well. I thought the best way to achieve this was to use multiple NIB files. When I prototyped this by have one view that creates content, switches to the next view, and then back, the content on the original view was reset. How do I make it so that the first view doesn't reset the data each time it's loaded? Thanks!

  • How do I add an SVN remote to a Git repository?

    - by Tom
    Hello! I recently used git-svn to clone an SVN repository, for the purposes of maintaining my own branch of an open-source project. I'm also working with others on this branch, so we use a shared Git repository to help with the collaboration. A colleague wishes to fetch new revisions from the original SVN repository. How might he accomplish this? I can simply run "git svn fetch" on my local machine, but seeing that my colleague has cloned from the shared Git repository, his local branch lacks the necessary SVN metadata for fetching. Thanks!

  • Exposing a "dumbed-down", read-only instance of a Model in GAE

    - by Blixt
    Does anyone know a clever way, in Google App Engine, to return a wrapped Model instance that only exposes a few of the original properties, and does not allow saving the instance back to the datastore? I'm not looking for ways of actually enforcing these rules, obviously it'll still be possible to change the instance by digging through its __dict__ etc. I just want a way to avoid accidental exposure/changing of data. My initial thought was to do this (I want to do this for a public version of a User model): class ReadOnlyUser(db.Model): display_name = db.StringProperty() @classmethod def kind(cls): return 'User' def put(self): raise SomeError() Unfortunately, GAE maps the kind to a class early on, so if I do ReadOnlyUser.get_by_id(1) I will actually get a User instance back, not a ReadOnlyUser instance.

  • How Proxy server works with tcp/http connections?

    - by Vivek
    Since I am a beginner in the world of internet/networking, I always mess up with these kinds of doubts in my head while programming ;) .. My doubts are, While working behind a proxy, how my requests and responses work? Means my request headers and data will first reach to Proxy server- then proxy server sends it(same headers and data) to corresponding server. And server responses to it with a response header and body to the proxy server-then proxy server sends it to my computer. Wright? While using websockets we are upgrading our http connection to tcp. At this time what is happening @ Proxy server? Does the proxyserver also upgrades its connection to plain TCP? After opening such TCP connections, does the proxy server able to track/log those socket messsages? And most importantly, Is the proxy server transparent or acting like an original server infront of a client? Thanks for any answers or helpful links in advance.

  • git squash and preserve last commit's timestamp

    - by Crend King
    Consider I have commits ... -- A -- B -- C If I use git rebase -i to squash all three commits into one, we could pick A squash B squash C I see the resulted commit A has its original timestamp. How could make it inherit the timestamp of commit C (the last one)? What I can think of is git commit --amend --date=<new_time>, but I need to remember the timestamp of commit C before squash or from reflog. I find the timestamp of the latest timestamp is more reasonable, because it show when do I actually finish the work that are in the commits. Thanks.

  • How to feed an xml database with tags obtained thru html forms ?

    - by blaise1
    Hello! Not a programmer, I begin with xml, html forms and xslt on Mac. I plan to use a form to post short texts in a xhtml page and invite end users to add some annotations to the said text. The users would select a specific part of the text posted and each annotation would stand for one specific chain of characters. My goal is to consolidate the tags obtained from various user's annotations to one xml "knowledge base" containing the original text with all the revision indicators. Then I plan to use xslt sheets to product various reports based on the tags obtained. my two questions are : 1- am I dreaming ? Is it really possible to do that with xml, xforms, xslt without using java, php, ajax or other seasoned programmer's tools ? 2- What should be my focus for further explorations aiming in that direction ? Which schema, events, sequences should I study ? Je vous remercie à l'avance, Please excuse my English. Blaise

  • checksum error with building an HTTP packet(but over TCP, like syn/ack its ok)

    - by Hila
    I am building a NAT program,I change each packet that comes from our internal subnet, change it's source IP address by libnet functions.( catch the packet with libpcap, put it sniff structures and build the new packet with libnet) I am trying to build an http packet. When I look on wireshark, I see that the new packet that I have built is exectly like the original packet(the only diffrent is that I changed the src port and ip), but there is a checksum error, So the server don't do anything with the packet that I have sent to him, beacuse the cheksum field is wrong. When I send a tcp packet(like syn or ack), the checksum is ok, and the server respons. Is anyone knows what can cause this problem? the new checksum in other packets is calculated as it should be.. but in the HTTP packet it doesn't..

  • Entity Framework 5 upgrade from 4

    - by user1714591
    I'm having an issue with the Where clause in a search, in my original version EF4 I could add a Where clause with 2 parameters, the where clause (string predicate) and a ObjectParameter list such as var query = context.entities.Where(WhereClause.ToString(), Params.ToArray()); since my upgrade to EF5 I don't seem to have that option am I missing something? This was originally used to build dynamic where clause such as "it.entity_id = @entity_id" then holding the variable value in the ObjectParameter. I'm hoping I don't have to rewrite all the searches that have been built out this way, so any assistance would be greatly appreciated. Cheers

  • Licensing Scripts

    - by Mr.K
    Hi, I've had my first nightmare client recently who was messing me around with payment for a project. So... I've come to an agreement with another client to use some of the sites scripting to build a site for them. But, now the original client wants their site too. I have made a deal to licence the reused parts of the site (some jQuery scripts and a dynamic flash gallery) rather than me signing over full copyright. However, I haven't got a clue how to do this. Can anyone point me in the right direction to read up on this? Thanks

  • PHP to C# and Vice versa

    - by Daniel Sh.
    I'm in this project: A web page that's gonna be used by the front-end company people to query and update data from a SQL DB. I'm working with visual studio and the code behind (C#) is almost done, so the interactions between SQL and C# and ok. My original idea was to work with ASP.NET which is familiar to me, but that's not gonna be possible. I have to switch to PHP. So, today is my first day learning PHP, checking http://php.net/manual/en/index.php and a lot of things seem quite similar to ASP.NET so I guess it won't be that hard. Anyways, some questions popped up quite fast as I wanted to script something else than a "hello world" . Is there an easy way to get/send C# variables from my class using a php page? I've read soemthing about using XML in order to do so, but still I'm scratching my head, is there another, easier, way to do this?

  • How to create a function and pass in variable length argument list?

    - by Jian Lin
    We can create a function p in the following code: var p = function() { }; if (typeof(console) != 'undefined' && console.log) { p = function() { console.log(arguments); }; } but the arguments are passed like an array to console.log, instead of passed one by one as in console.log(arguments[0], arguments[1], arguments[2], ... Is there a way to expand the arguments and pass to console.log like the way above? Note that if the original code were var p = function() { }; if (typeof(console) != 'undefined' && console.log) { p = console.log; } then it works well on Firefox and IE 8 but not on Chrome.

  • Large number of tables and Hibernate memory consumption

    - by Vedran
    I'm working on a large ERP project which has database model with about 2100 tables. With "only" 500 tables mapped with Hibernate, application deployed on the web server takes about 3GB of working memory. Is there any way to reduce Hibernate's metamodel memory footprint when using that many tables in one persistence unit? Or should I just give up on ORMs and go with plain old JDBC (or even jOOQ)? Right now I'm using Hibernate 4.1.8, Spring 3.1.3, JBoss AS 7.1 and working with MSSQL database. Edit: JavaMelody memory histogram output - with 2000 generated test tables that are a bit smaller in scope from the original db model (hence 'only' 1.3GB of spent memory)

  • One-way flight trip problem.

    - by psihodelia
    You are going on a one-way indirect flight trip that includes billions transfers. You are not stopping twice in the same airport. You have 1 ticket for each part of your trip. Each ticket contains src and dst airport. All the tickets you have are randomly sorted. You forgot the original departure airport (very first src) and your destination (last dst). Design an algorithm to reconstruct your trip with minimum big-O complexity.

  • Is there any "modern" text editor with command-line?

    - by Pedro Morte Rolo
    A command line in a text editor is a wonderful feature. It allows the user to explore the editor's functionality and learn it's shortcuts in a textual way. It's much faster than using the mouse, and it is much easier to memorise "shortcuts" this way. Emacs and VI provide this, though, emacs and vi are not "modern". By "modern", I mean one that is original built to cope with the modern de-facto standards of selecting, copying, pasting, cutting, undoing, redoing and auto-completing. Cream/vi or EmacsCUE are not valid options, since there are loads of things built over them that conflict with the mentioned stuff. Is there any alternative? (I do not intend to use the "modern" term as derrogatory. I love both Emacs and VI, but I hate their keyboard shortcut baggage.) (please do not advertise Vim and Emacs, that's not answering the question. I am asking for alternatives)

  • Replace token in ANTLR

    - by user1019710
    I want to replace a token using ANTLR. I tried with TokenRewriteStream and replace, but it didn't work. Any suggestions? ANTLRStringStream in = new ANTLRStringStream(source); MyLexer lexer = new MyLexer(in); TokenRewriteStream tokens = new TokenRewriteStream(lexer); for(Object obj : tokens.getTokens()) { CommonToken token = (CommonToken)obj; tokens.replace(token, "replacement"); } The lexer finds all occurences of single-line comments, and i want to replace them in the original source too.

  • Create "duplicate copy" of github repository

    - by user1483934
    I see answers to similar questions and I'm sure I may just not be familiar enough with Git and Github terminology to know if they apply to my question. What I need to do is to clone an existing Github remote repository (a private repo under another person's username that I have contributor access to) and create a new private remote repo under my account. The existing repo user is going to make significant alterations to the repo, delete, and re-push, before they do that they want me to clone and create a duplicate so we can continue working from the repo under my user. I want to preserve the commit history with the repo if possible. I've cloned locally but don't can't seem to figure out how to push it to a new remote that isn't origined to the original user.

  • Cloud sync between iPad/iPhone app

    - by Macatomy
    I have a Core Data app that will end up being an iPhone/iPad universal application. I would like to implement cloud syncing so that an iPhone and an iPad both running the app could share data. I'm planning to use the recently released Dropbox API. Does anyone have any thoughts on the best way to go about doing this? The Dropbox API allows for apps to store files on the cloud. What I was thinking was to original store the database (sqlite) for the app on the cloud and then download that database, but I then realized that using that method would make it painfully difficult to merge changes (rather than replacing the whole database). Any thoughts are appreciated. Thanks.

  • Is there a way to convert code to a string and vice versa in Python?

    - by Dragos Toader
    The original question was: Is there a way to declare macros in Python as they are declared in C: #define OBJWITHSIZE(_x) (sizeof _x)/(sizeof _x[0]) Here's what I'm trying to find out: Is there a way to avoid code duplication in Python? In one part of a program I'm writing, I have a function: def replaceProgramFilesPath(filenameBr): def getProgramFilesPath(): import os return os.environ.get("PROGRAMFILES") + chr(92) return filenameBr.replace("<ProgramFilesPath>",getProgramFilesPath() ) In another part, I've got this code embedded in a string that will later be output to a python file that will itself be run: """ def replaceProgramFilesPath(filenameBr): def getProgramFilesPath(): import os return os.environ.get("PROGRAMFILES") + chr(92) return filenameBr.replace("<ProgramFilesPath>",getProgramFilesPath() ) """ How can I build a "macro" that will avoid this duplication?

  • element height after content change

    - by Neph
    I have a snippet of code that alters the contents of a DIV to match the contents of a textarea and then applies the height change in the DIV to the textarea element. function growTextArea(parameter) { $('div').find("[data-fieldid='1_description']").text($(parameter).val()); // No Works height = $('.hiddenDiv').find("[data-fieldid='1_description']").outerHeight(); alert(height); // Works heightDiv = $('.hiddenDiv').outerHeight(); alert(heightDiv); $(parameter).css('height', $('div').find("[data-fieldid='1_description']").outerHeight()); } The DIV contents change properly, so the search function is working properly, however the search function always returns the original height of the DIV. The function is called by onKeyUp in the textarea. If the .find is swapped out for a .hiddenDiv the height change is reflected properly.

  • MultiOS "Jet Database" for QtC++?

    - by Airjoe
    Hopefully I can articulate this well: I'm porting an application I made years ago from VB6 (I know, I know!) to QtC++. In my original application, one thing I liked was that I didn't need an actual SQL server running, I could just use MS Access .mdb files. I was wondering if something similar exists for QtC++ that will work on multiple OSes- a database stored in a file, pretty much, but that I can still run SQL queries with. Not sure if something like this exists or not, but any help appreciated, thanks!
