• PHP automaticly parses my string?

  - by PlagueEditor

  Some Background info: My web application stores some XML in a Text column of the MySQL database. This XML represents a transaction for the application. The problem occurs when I'm testing my library. Within PHP, I have a string: $s="<flist><transaction amount=\"10\" type=\"income\">Initial Amount</transaction></flist>"; However, whenever I echo or consecrate this string, it turns into "Initial Amount". Am I missing a feature of PHP? How can I fix this? Wow! As I'm creating this post, StackOverflow is transforming that XML into $s=Initial Amount as well... Please help... Thank-you for your time as this completely perplexes me.

• The glutKeyboardFunc does not react to key presses immediately

  - by Nibirue

  I have a function glutKeyboardFunc(keyboard), where keyboard has: void keyboard(unsigned char key, int x, int y){ float alpha = 1.0; switch(key){ case 'c': glClearColor(1,0,0,alpha); printf("success"); break; } } This is a summary of the function; it works properly, but only once some other action has occurred. For instance, the printf statement reports success immediately on keystroke 'c', but the background color does not become active until I click somewhere else on the canvas. I want all keystrokes to have an immediate effect.

• What are the requirements to consider someone as a Software Engineer? Is it just a job title? [close

  - by mike

  I am employed as a Software Engineer with a background in C# and .NET. I am trying to interface with an web API. I asked for help because I didn't know to connect to it or handle the results. Someone told me that I shouldn't consider myself a Software Engineer because I didn't know to how to do it. They said the API was well documented, required no authentication, and returned XML that I could easily parse. They said the documentation should be enough to figure out how to use the API. Isn't having a job title of Software Engineer the only consideration for being a Software Engineer?

• Creating an OpenGL texture with alpha using NSBitmapImageRep

  - by BROK3N S0UL

  I am loading a PNG using: theImage = [NSBitmapImageRep imageRepWithContentsOfFile:imagePath]; from which I can successfully create a gl texture and render correctly without any transparency. However, when I switch blending on using: glEnable(GL_BLEND); glBlendFunc(GL_SRC_ALPHA, GL_ONE); The texture renders with the correct transparent background, but the image colours are incorrect. I have tried several options in the blend function, GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA, GL_ONE, GL_DST_ALPHA, etc. I was taught maybe I need to reorder the bits in the image data, maybe the channels have been mixed up, but I would not expect it to render correctly when blending is off in that case. Alternatively, I could use libPNG I guess, but I would like to try using a NSBitmapImageRep if it is possible.

• Put Raphael (SVG) canvas behind other divisions to make them clickable?

  - by Kerry

  I am using Raphael to create lines between divisions in an organization chart (or flow chart), but I need to be able to actually click on the divisions and content behind it. If I could make the canvas be behind the other elements, kind of like a background image, that would be idea. Is this possible? UPDATE: I found a solution. Raphael makes an SVG canvas that is absolutely positioned in my case. Absolute positions act as layers, and so to be on top of that layer, my content had to be absolutely positioned as well. If someone else has a better solution, I would be happy to hear it, though this is working fine.

• Is there a way to determine the current Outlook activity level?

  - by dlittau

  I am working on an Outlook 2007 Add-in in C# (VS2008) and we want to send some background email items only when Outlook is not busy doing something else. Is there a .net way to see if Outlook is busy doing other things (perhaps due to other add-ins or the like taking up CPU cycles)? Alternately, is there a way to send emails such that they never appear in the Outbox? We need a method that would not require any additional software be installed. Thanks for any input.

• Rails: Thread won't affect database unless joined to main Thread

  - by hatboysam

  I have a background operation I would like to occur every 20 seconds in Rails given that some condition is true. It kicked off when a certain controller route is hit, and it looks like this def startProcess argId = self.id t = Thread.new do while (Argument.isRunning(argId)) do Argument.update(argId) Argument.markVotes(argId) puts "Thread ran" sleep 20 end end end However, this code does absolutely nothing to my database unless I call "t.join" in which case my whole server is blocked for a long time (but it works). Why can't the read commit ActiveRecords without being joined to the main thread? The thread calls methods that look something like def sample model = Model.new() model.save() end but the models are not saved to the DB unless the thread is joined to the main thread. Why is this? I have been banging my head about this for hours.

• Wordpress sidebar border

  - by Crays

  Hi, i would like to add an image that acts like a border after every list in the sidebar. I knew it has something to do with this #sidebar h2 { border-bottom: 1px solid #d6d6d6; } since i tried that code and a border appeared. But what i wanted is a picture, i could do that with in the posts with: .TitleBorder { background: url(images/border.png) repeat-x; height: 3px; width: 615px; } and <div class="TitleBorder"></div> but in sidebar, i can't do that. Any help?

• Android: how to convert whole ImageView to Bitmap?

  - by yosh

  I have my application that is displaying images with different ratio, resized inside (centerInside) imageView. What I need is to create bitmap from the ImageView including the background (black in this case). So for example I have device screen 320x480, full screen imageView with image resized to 280x480. How could I get 320x480 bitmap from it? On top of this imageview I have some logos or buttons that I don't want to include to bitmap, they're like on top layer. All I need is bitmap with image and black border from some sides.

• Most optimal way to detect if black (or any color pixels) exist in an image file?

  - by Zando

  What's the best and most flexible algorithm to detect any black (or colored pixel) in a given image file? Say I'm given an image file that could, say, have a blue background. And any non blue pixel, including a white pixel, is counted as a "mark". The function returns true if there are X number of pixels that deviate from each other at a certain threshold. I thought it'd be fastest to just simply iterate through every pixel and see if its color matches the last. But if it's the case that pixel (0,0) is deviant, and every other pixel is the same color (and I want to allow at least a couple deviated pixels before considering an image to be "marked), this won't work or be terribly efficient.

• Help constructing query - Compare columns and replace numbers

  - by Tommy

  I have a feeling that this query is pretty easy to construct, I just can't figure it out. I want to replace all numbers in table X column C, with numbers in table Z column A, where numbers from table X column C matches numbers in table Z column B. I hope that makes sense. Perhaps a little background information will make it clearer. I've converted from one CMS to another, and the module I used to convert mapped the ids to the new database. Table X column A is the new id's. Table X column B is the old id's. Table Z is the table for an image gallery that I migrated, and column C contains the id's of the images owners. Can anyone crack this nut?

• Large amount of constants in Java

  - by Lars D

  I need to include about 1 MByte of data in a Java application, for very fast and easy access in the rest of the source code. My main background is not Java, so my initial idea was to convert the data directly to Java source code, defining 1MByte of constant arrays, classes (instead of C++ struct) etc., something like this: public final/immutable/const MyClass MyList[] = { { 23012, 22, "Hamburger"} , { 28375, 123, "Kieler"} }; However, it seems that Java does not support such constructs. Is this correct? If yes, what is the best solution to this problem?

• Java sockets: can I write a TCP server with one thread?

  - by hmp

  From what I read about Java NIO and non-blocking [Server]SocketChannels, it should be possible to write a TCP server that sustains several connections using only one thread - I'd make a Selector that waits for all relevant channels in the server's loop. Is that right, or am I missing some important detail? What problems can I encounter? (Background: The TCP communication would be for a small multiplayer game, so max. 10-20 simultaneous connections. Messages will be sent about every few seconds.)

• networkstream always empty!

  - by ALEX

  hey I'm writing on an Server-Client program but when my client sends something, it never reaches my server! I'm sending like this: public void Send(string s) { char[] chars = s.ToCharArray(); byte[] bytes = chars.CharToByte(); nstream.Write(bytes, 0, bytes.Length); nstream.Flush(); } and Receiving in a background thread like this void CheckIncoming(object dd) { RecievedDelegate d = (RecievedDelegate)dd; try { while (true) { List<byte> bytelist = new List<byte>(); System.Threading.Thread.Sleep(1000); int ssss; ssss = nstream.ReadByte(); if (ssss > 1) { System.Diagnostics.Debugger.Break(); } if (bytelist.Count != 0) { d.Invoke(bytelist.ToArray()); } } } catch (Exception exp) { MSGBOX("ERROR:\n" + exp.Message); } } the ssss int is never 1 whats happening here???

• Offsite data storage for simple app, or a similar supported persistence mechanism?

  - by jdk

  Question Is there a usable facebook entry point to the Data Storage API that facebook lists on their app admin page for developers, or should I consider an alternate mechanism? What alternative mechanisms exist to simply persist my information offsite (away from my server app) without stuffing it into a cookie that's prone to expire? ... Background The facebook Data Store Admin tool is made available in a facebook App's Settings as seen here: (continue reading below) However when I visit the DataStoreAdmin link nothing works (i.e. clicking the buttons to define the data store types and objects does nothing - I have tried different browsers). The Wiki page for Data Store API hasn't been updated recently and the second last update says the beta Data Store was taken offline. It seems odd the link would be readily available and highly visible at the top of the App configuration area if indeed it's defunct. I was hoping some kind of key/value pair solution to remove the data calls from my own server.

• Why are Objective-C instance variables declared in an interface?

  - by Chase

  I'm just getting into Objective-C (Java is my primary OO language). Defining an object's instance variables in the interface instead of the class seems strange. I'm used to an interface being a public API definition with nothing besides method signatures (not counting constants here). Is there some reason that state is defined in an interface (even if it is private) and behaviour is defined in a class. It just seems odd that since objects are state+behavior that the definition would be split into two separate places. Is it a design benefit is some way? A pain in the rear issue that you are just forced to deal with in Objective-C? A non-issue, just different? Any background on why it's done this way? Or can you put object state in a class and I just haven't hit that part in my book yet?

• Why are some strings displayed as garbage when I scroll my read-only multiline Win32 edit control ve

  - by sharptooth

  In my native C+ Win32 GUI application I have a property sheet with two property pages. One of the property pages contains an edit box: EDITTEXT IDC_EDIT_ID,x,y,width,height,ES_MULTILINE | ES_READONLY | NOT WS_BORDER | WS_VSCROLL | WS_HSCROLL | NOT WS_TABSTOP,WS_EX_STATICEDGE I set a multiline text to this edit box. The text has more lines than the edit can fit, so some of the text is clipped and a vertical scroll bar appears. When I scroll up with the mouse the lines that come "from under clip area" are drawn as garbage - it looks like first one line is drawn, then some other line is drawn on the same place without first painting the background. The lines that just move up - ones that were visible before scrolling and remain visible after scrolling are displayed allright. What's the reason and workaround for this behavior?

• How to tell an iphone app user what will happen before opening Facebook login dialogue

  - by docno

  Apps that allow users to log in over a 3rd party authentication provider (e.g. Facebook, Google, Twoitter,...) should open a browser window to let the user authenticate against the provider. That means, at some point, an app is backgrounded and the user interacts with a browser window. Just before the browser opens, it's a recommended pratctice to inform the user about what will happen (see e.g. Getting Started with OAuth 2.0 - O'Reilly), let's say an alert window with something like "you will leave now the XYZ app and a browser window will open where you can enter your credentials safely". My question: How can that be done if I use the facebook SDK for ios? Looking at the SDK, there seem to be no notifications and no designated states that would allow me to detect that the sdk is about to background my app and about to opening either Safari or the Facebook app.

• Is it possible to create a Service that listens for hardware key presses?

  - by VoteBrian

  I'd like to run an Android background service that will act as a keylistener from the home screen or when the phone is asleep. Is this possible? From semi-related examples online, I put together the following service, but get the error, "onKeyDown is undefined for the type Service" public class ServiceName extends Service { @Override public void onCreate() { //Stuff } public IBinder onBind(Intent intent) { //Stuff return null; } @Override public boolean onKeyDown(int keyCode, KeyEvent event) { if(event.getAction() == KeyEvent.ACTION_DOWN) { switch(keyCode) { case KeyEvent.KEYCODE_A: //Stuff return true; case KeyEvent.KEYCODE_B: //Stuff return true; //etc. } } return super.onKeyDown(keyCode, event); } } I realize Android defaults to the search bar when you type from the home screen, but this really is just for a very particular use. I don't really expect to distribute this. Also, it'd be nice to use the camera button to wake the phone.

• Database table schema design - varchar(n). Suitable choice of N

  - by morpheous

  Coming from a C background, I may be getting too anal about this and worrying unnecessarily about bits and bytes here. Still, I cant help thinking how the data is actually stored and that if I choose an N which is easily factorizable into a power of 2, the database will be more effecient in how it packs data etc. Using this "logic", I have a string field in a table which is a variable length up to 21 chars. I am tempted to use 32 instead of 21, for the reason given above - however now I am thinking that I am wasting disk space because there will be space allocated for 11 extra chars that are guaranteed to be never used. Since I envisage storing several tens of thousands of rows a day, it all adds up. Question: Mindful of all of the above, Should I declare varchar(21) or varchar(32) and why?

• Sharepoint 2010 - Managed KeyWords

  - by Audioillity

  Hi, Is it possible to import managed keywords into SharePoint 2010? Where are the keywords stored within which database? Background - I'm currently working on a migration from a legacy system into SharePoint 2010. So far everything is going well, and I can even bring across the managed meta data across along with most other data. The process I use was built for SharePoint 2007 to update Lists over SOAP. With a few manual tweaks I've managed to get the metadata to come across. To bring across either managed metadata or managed keywords I need to know the ID for the existing label/keyword. I have this for the Managed Metadata however not for the Managed Keyword. Currently I create a CSV file to be imported for managed metadata before working out the reverent GUID for the source label. Many Thanks Luke

• Go to file in Visual Studio

  - by Effata

  I've recently started a new job working with webdevelopment in .NET. Coming from a php and rails background i've been working mainly in Eclipse and NetBeans, along with some TextMate. I find myself missing a few great keyboard shortcuts and i can't seem to find a Visual Studio equivalent. NetBeans has the awesome "Go To File" and so does Eclipse with this plugin. Eclipse also has the option of quick searching in the open file list with Cmd/Ctrl-E. Is there something like this in Visual Studio? Either build in or via plugin. Or is there some other way of quickly navigating between files that's prefered?

• How to create a MySQL query for time based elements with a 'safe window'?

  - by pj4533

  I am no SQL expert, far from it. I am writing a Rails application, and I am new at that as well. I come from a desktop programming background. My application has a table of data, one of the columns is the time at which the data was logged. I want to create a query with a 'safe window' around EACH row. By that I mean, it returns the first row, then for X minutes (based on the timelogged column) it won't return any data, once X minutes is up, it will return the next row. For example: ID | TimeLogged 1 | 3/5/2010 12:01:01 2 | 3/5/2010 12:01:50 3 | 3/5/2010 12:02:03 4 | 3/5/2010 12:10:30 5 | 3/5/2010 01:30:03 6 | 3/5/2010 01:31:05 With a 'safe window' of 5 minutes I want to create a query to return: 1 | 3/5/2010 12:01:01 4 | 3/5/2010 12:10:30 5 | 3/5/2010 01:30:03 (It skipped the 12:01:50 and 12:02:03 items because they occurred within 5 minutes of the first item.) Another example, with a 'safe window' of 15 minutes I want to return: 1 | 3/5/2010 12:01:01 5 | 3/5/2010 01:30:03 Perhaps I have to just return all data and parse it myself?

• C/C++ enums: Detect when multiple items map to same value

  - by Dan

  Is there a compile-time way to detect / prevent duplicate values within a C/C++ enumeration? The catch is that there are multiple items which are initialized to explicit values. Background: I've inherited some C code such as the following: #define BASE1_VAL (5) #define BASE2_VAL (7) typedef enum { MsgFoo1A = BASE1_VAL, // 5 MsgFoo1B, // 6 MsgFoo1C, // 7 MsgFoo1D, // 8 MsgFoo1E, // 9 MsgFoo2A = BASE2_VAL, // Uh oh! 7 again... MsgFoo2B // Uh oh! 8 again... } FOO; The problem is that as the code grows & as developers add more messages to the MsgFoo1x group, eventually it overruns BASE2_VAL. This code will eventually be migrated to C++, so if there is a C++-only solution (template magic?), that's OK -- but a solution that works with C and C++ is better.
