• Remove margin between rows of overflowing inline elements

  - by Ian

  I'm creating a tile-based game and am using block rendering to update a large list of tiles. I'm attempting to do this in the most simple manner, so I've been trying to work with HTML's default layouts. Right now I'm creating 'inline-blocks', omitting whitespace between the elements to avoid horizontal spaces in between them but when the blocks overflow and create a new line there is some vertical margining in which I do not know how to remove. Example to make this a bit clearer: http://jsfiddle.net/mLa93/13/ (Pretty much I just need to remove the spacing between the block rows while retaining the simple markup.)

• calling a service layer method to my presentation layer

  - by Josepth Vodary

  Ok I feel really dumb asking this but I seem to be missing something really simple here. I have the following code in a class in my service layer - public Items getItems(String category, float amount, String color, String type) The code reads from a database and returns the results - I plan on placing it in a jframe. Nice and simple. But no matter how I call it from the jframe I get errors in eclipse that the code is wrong - either that their are illegal modifiers or such. So obviously I am calling it completely wrong, so my stupid question is how do you call that method into a jframe? For example - if I try to call it this way: public Items getItems(); I get told that getItems is an illegal parameter. If I call this.. Items getItems(); I am told its undefined

• Upload Image to Facebook Objective-C

  - by boopyman

  I'm currently trying to upload an image from my Mac application to Facebook. To do this, I'd like for the user to simply input his username and password, and to click a button. The only issue is, Facebook doesn't actually have an API for the Mac, it only has one for iOS. This shouldn't be a problem, except for the fact that to login, you must use a web view, something I'm not to keen on doing, since I'd like the interface to be two simple text fields. I've also looked into PHFacebook, a class I found online, but it also seems to utilize an NSWebView. I'm wondering if there's a security issue when you use text fields; indeed, it's slightly strange no available API offers this function ! So, to conclude, is it possible, or is there an API, that lets you upload an image and lets you provide the user's credentials through simple NSStrings?

• Entity Framework with SQL Server 2000 (APPLY Operator) issue

  - by How Lun

  Hello, I have a simple Linq query below: var seq = (from n in GetObjects() select n.SomeKey) .Distinct() .Count(); This query works find with SQL Server 2005 and above. But, this start to give headache when I hooked the EF to SQL Server 2000. Because EF is using APPLY operator which only SQL Server 2005 and above can be supported. I do not know why the hell EF is using APPLy operator instead of sub queries. My current work around is: var seq = (from n in GetObjects() select n.SomeKey) .Distinct() .ToList() .Count(); But, I can forsee more problems to come. The above query is just a simple one. Did anyone come across such issue? And how you guys work around it? Or is there a way to force EF not to use APPLY operator? Any help will be very much appreciated. How Lun.

• Please help me with this Ruby code

  - by Bragaadeesh

  Hi, I am new to Ruby and I know that I am not using the simple and powerful methods available within it. I made my code work but it has to be simple not this huge (especially I feel I am very bad at loop variables) i = 0 j = 0 loop_count = ((to_date-from_date)/(60*60*24)).to_i#diff b/w two dates in days loop_count.times do 48.times do event = Icalendar::Event.new status = get_availability_on_date_and_hour(@templates, @availabilities, from_date+j.days, i).downcase if(status != 'unavailable') #Initialize start and end dates in DateTime's civil format bias_date_time = DateTime.civil(from_date.year, from_date.month, from_date.day) event.dtstart = bias_date_time + j.day + (i/2).to_i.hour + (i%2*30).to_i.minutes event.dtend = event.dtstart + 30.minutes event.summary = status.upcase cal.add_event(event) end i += 1 end i = 0 j += 1 end

• "public" or "private" attribute in Python ? What is the best way ?

  - by SeyZ

  Hi ! In Python, I have the following example class : class Foo: self._attr = 0 @property def attr(self): return self._attr @attr.setter def attr(self, value): self._attr = value @attr.deleter def attr(self): del self._attr As you can see, I have a simple "private" attribute "_attr" and a property to access it. There is a lot of codes to declare a simple private attribute and I think that it's not respecting the "KISS" philosophy to declare all attributes like that. So, why not declare all my attributes as public attributes if I don't need a particular getter/setter/deleter ? My answer will be : Because the principle of encapsulation (OOP) says otherwise! What is the best way ? Thanks !

• How to use .DefaultListCellRenderer

  - by loddn

  First, i'm new at Java-programming and my native lang is not english, but still i hope to get some help from you all. What I try to do is a simple java-interface with a jComboBox and a jList. I want to poplate to jComboBox with Object-names and when the user select one of the names get the object-id which i will use to populate the jList. It's probably simple but i have bin stuck with this problem all day. private void loadComboBox() { biz.Object object = new biz.Object(); try { ArrayList<biz.Object> arrayOfObjects= object.getAllObjects();// ArrayList of objects for (biz.Object o:arrayOfObjects) { if (o != null) cbm.addElement(o); //`toString-method } cb.setModel(cbm); //JComboBox

• Using a database/index sequential file independently of the Unix distribution

  - by Helper Method

  What I'm planning to do is a) parse a file for some lines matching a regular expression b) store the match in some sort of database / file so I don't have to do the parsing again and again c) call another program passing the matches as arguments While I can imagine how to do a) and c), I'm a little bit unsure about b). The matches are of the form key:attribute1:attribute2:attribute3 where attribute 2 may be optional. I'm thinking of storing the results in a simple database but the problem is the database needs to available on a number of Unix platform for the program to work. Are there any (simple) databases which can be found on any Unix platforms? Or should I use some sort of index-sequential file?

• Send files between python and C#

  - by SuitUp

  Hi, i would like to know, what is the best way to send files between python and C# and vice versa. I have my own protocol which work on socket level, and i can send string and numbers in both ways. Loops works too. With this i can send pretty much anything, like package of users id, if it is simple data. But soon i will start sending whole files, maybe xml or executables. Simple server with files is no an option because i want sending files from client too. I was thinking about serialization but i don't know it is the best solution, but if it is i will love some tips from stackoverflow community.

• Downloading game assests to SD card on Android

  - by hgpc

  I'm developing an Android game that has to download some assets to the SD card to keep the size of the app as small as possible. I was thinking of using an uncompressed zip file to bundle all the assets. A requirement from the client is to protect these assets as much as possible. Being part of the apk is considered enough protection, but if I do this the apk size will be enormous. If I just put a zip bundle in the SD card, then anyone can unzip it and explore its contents. Is there a simple way to do this without retorting to horrid DRM? Obviously if someone really wants to check the resources of an Android game, they can. I'm just looking for a simple solution to avoid making this very easy.

• Robust Way of Selecting All Text in Textbox

  - by Emil

  I'm trying to have the content of the an HTML textbox be selected fully onFocus. I know the simple solution of putting a onfocus="this.select()" on the component but this is not a good solution because if a user double clicks into the area the selection is lost and in browsers like chrome it is rarely working like it should and just reverts into input form. I have searched on Google for a little while and can't find a good solution, most suggestions are of this simple solution. What I would like it is that the selection inside the textbox not change once selected and if possible the user should not be able to edit the content of the textbox, for example if you have used AdSense when you grab code from AdSense the selection never changes and your unable to alter the code in the textbox. Any solutions would be appreciated.

• Why can't i call Contains method from my array?

  - by xbnevan

  Arrrg!I am running into what i feel is a dumb issue with a simple script i'm writing in powershell. I am invoking a sql command that is calling a stored proc, with the results i put it a array. The results look something like this: Status ProcessStartTime ProcessEndTime ------ ---------------- -------------- Expired May 22 2010 8:31PM May 22 2010 8:32PM What i'm trying to do is if($s.Contains("Expired")) , report failed. Simple...? :( Problem i'm running into is it looks like Contains method is not being loaded as i get an error like this: Method invocation failed because [System.Object[]] doesn't contain a method named 'Contains'. At line:1 char:12 + $s.Contains <<<< ("Expired") + CategoryInfo : InvalidOperation: (Contains:String) [], RuntimeException + FullyQualifiedErrorId : MethodNotFound So, what can i do to stop powershell from unrolling it to string? Actual ps script below - $s = @(Invoke-Sqlcmd -Query "USE DB GO exec Monitor_TEST_ps 'EXPORT_RUN',NULL,20 " ` -ServerInstance "testdb002\testdb_002") if ($s.Contains("Expired")) { Write-Host "Expired found, FAIL." } else { Write-Host "Not found, OK." }

• I created a Python egg!!! Now... what do I do with it?

  I've finally figured out how to create a Python egg and gotten it to work. Now... what do I do with it? How do I use it? How do I ensure that everything was correctly included? (Simple steps please... not just redirection to another site. I've googled, but it's confusing me, and I was hoping someone could explain it in a couple of simple bullet points or sentences.)

• Waiting for ServerSocket accept() to put socket into "listen" mode

  - by inazaruk

  I need a simple client-server communication in order to implement unit-test. My steps: Create server thread Wait for server thread to put server socket into listen mode ( serverSocket.accept() ) Create client Make some request, verify responses Basically, I have a problem with step #2. I can't find a way to signal me when server socket is put to "listen" state. An asynchronous call to "accept" will do in this case, but java doesn't support this (it seems to support only asynchronous channels and those are incompatible with "accept()" method according to documentation). Of cause I can put a simple "sleep", but that is not really a solution for production code. So, to summarize, I need to detect when ServerSocket has been put into listen mode without using sleeps and/or polling.

• Download File from Web C++ (with winsock?)

  - by Lienau

  I need to download files/read strings from a specified url in C++. I've done some research with this, cURL seems to be the most popular method. Also, I've used it before in PHP. The problem with cURL is that the lib is huge, and my file has to be small. I think you can do it with winsock, but I can't find any simple examples. If you have a simple winsock example, a light cURL/Something else, or anything that could get the job done. I would greatly appreciated. Also, I need this to work with native C++.

• Can I distort a bitmap image in Flash?

  - by drpepper

  Hi, what I would like to do is to take a loaded GIF file as a Bitmap, and then distort it by stretching and shrinking parts of it, so it would look like it got squished up against the screen. I'm pretty sure that there's no easy way in Flash to go beyond scaling and shearing, but I wonder if there might be some simple techniques to accomplish this kind of effect. By the way, I've also thought of pre-deforming the images in GIMP and saving them there, but I can't find a simple way to do it without learning their scripting language. Thanks for your help!

• C# - Saving a DataGridView to file and loading

  - by Rekar

  Hello, To start off, what I have is a simple Winforms app, with just a save and load button, and with a datagridview control to hold data. What I am looking to do is input some data into the control, hit the save button, and it save all the data to a file locally on the computer, and when I hit load, it loads the file and populates the control appropriately, keeping all rows, columns, and data the same as when saved. Although it sounds fairly simple to me, I cant seem to figure a good way to save and load the data. Can I get a few pointers or examples to get myself started? Thank you.

• The best way to store username and password without a database

  - by Mokuchan

  Hello everyone, I want to build a simple single user login "library" in PHP, but I'm facing the following dilemma: how should I store username and password if I'm not using a database? A simple plain text file could be easily read and then the password could be easily decripted so that's not an option. If I create a php file with just <?php $Username= "username"; $Password= "password"; ?> then no one should be able to read it and I could simply include this file where I need it, but I'm not really sure you can't find a better way to do this! So what's, in your opinion, the best solution to this problem (and why)? Thanks

• Low-overhead way to access the memory space of a traced process?

  - by vovick

  Hello all. I'm looking for an efficient way to access(for both read and write operations) the memory space of my ptraced child process. The size of blocks being accessed may vary from several bytes up to several megabytes in size, so using the ptrace call with PTRACE_PEEKDATA and PTRACE_POKEDATA which read only one word at a time and switch context every time they're called seems like a pointless waste of resources. The only one alternative solution I could find, though, was the /proc/<pid>/mem file, but it has long since been made read only. Is there any other (relatively simple) way to do that job? The ideal solution would be to somehow share the address space of my child process with its parent and then use the simple memcpy call to copy data I need in both directions, but I have no clues how to do it and where to begin. Any ideas?
