• Fonts in a multi-platform environment

  - by Stephen Burke

  What is the best way to deal with fonts in a multi-platform distributed system? If I want to use a common font across all systems to show to the user, what's the best way to do this. From the little I've been reading each platform looks to have fonts that are of the same family (ie serif, sans-serif) but with different names. CSS looks to have the functionality baked in where it will make the best selection it can of font on the users machine. Is there similar functionality either in system libraries or external libraries for Windows & Linux. I'm using C++ mainly? Can someone point me in the right direction for documentation as well? Thanks

• Problem with multi-table MySQL query

  - by mahle

  I have 3 tables. Here is the relevant information needed for each. items prod_id order_id item_qty orders order_id order_date order_status acct_id accounts acct_id is_wholesale items is linked to order by the order_id and orders is linked to accounts via acct_id I need to sum item_qty for all items where prod_id=464 and the order stats is not 5 and where the is_wholesale is 0 and the order_date is between two dates. Im struggling with this and would appreciate any help. Here is what I have but it's not working correctly: SELECT SUM(items.item_qty) as qty FROM items LEFT JOIN orders ON orders.order_id = items.order_id LEFT JOIN accounts on orders.acct_id = accounts.acct_id WHERE items.prod_id =451 AND orders.order_date >= '$from_date' AND orders.order_date <= '$to_date' AND orders.order_status <>5 AND accounts.is_wholesale=0; Again, any help would be greatly appreciated!

• About Attributes member of LUID_AND_ATTRIBUTES used in TOKEN_PRIVILEGES structure

  - by Astaroth

  MSDN article, Enabling and Disabling Privileges in C++, provided the a code example to show how to enable or disable a privilege in an access token. I quote the part in questioned: tp.PrivilegeCount = 1; tp.Privileges[0].Luid = luid; if (bEnablePrivilege) tp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED; else tp.Privileges[0].Attributes = 0; What is the meaning of zero value for Attributes member? According to the documentation of TOKEN_PRIVILEGES structure, the attributes of a privilege can be a combination of the following values: SE_PRIVILEGE_ENABLED  (it is 0x00000002L in WinNT.h) SE_PRIVILEGE_ENABLED_BY_DEFAULT  (it is 0x00000001L in WinNT.h) SE_PRIVILEGE_REMOVED  (it is 0x00000004L in WinNT.h) SE_PRIVILEGE_USED_FOR_ACCESS  (it is 0x80000000L in WinNT.h) So, we don't see any valid constant with a value of zero. I guess, the zero is equal to SE_PRIVILEGE_REMOVED. Anybody here could explain what the zero value really does?

• Drawing a waveform in C#

  - by user488792

  Hi! I want to be able to display a WaveForm in C#, along with some simple features such as zooming and selection. I already have the data as a short[] of amplitude values. However, I am an amateur when it comes to hardcoding GUI. I have already found a possible helper class WaveFormClass that may help me achieve this but as a backup, I want to learn how to manually do it. So may I ask for some methods and possibly some links that will help? Thanks!

• 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.

• Many-to-Many Relationship (with properties) in Google App Engine for Java

  - by rvandervort

  I understand from the official documentation on unowned relationships that the app must use sets of Key objects on either side of the relationship. This makes perfect sense. Coming from many years of RDBM-style programming, though, I'm pretty confused about how I can model properties of that relationship itself. For example, if I have entities Category and Entry in my many-to-many relationship and would like to persist a dateAdded property, or some other data that are only relevant when both sides of the relationship are known. I suppose it would be possible to create a third class : CategoryEntry that links the two, but this seems like a kludge. What is the proposed way to model this kind of situation ?

• Handling orientation changes yourself

  - by synic

  From the documentation regarding the android:configChanges='orientation' attribute of the activity tag in the manifest: Note: Using this attribute should be avoided and used only as a last-resort. Please read Handling Runtime Changes for more information about how to properly handle a restart due to a configuration change. Why does it say this? In the case of threads and networking requests via a service API library, a request could be made with a reference to the original Activity, and then an orientation change could occur, leaving the thread pointing to the old Activity. While this can be fixed, it's tedious and ugly compared to just handling the configuration changes yourself. Why should it be avoided?

• Good Notification Plugin For Jquery?

  - by chobo2

  Hi I am looking at pines notify(http://pines.sourceforge.net/pnotify/) and it looks good but it seems to have little actual documentation so I am wondering is there anything more established and worked on out there? Like I don't want to spend time trying to figure out how to use pines and then find out it is missing some feature that I needed a few months later that I needed to change to a different plugin. This happened to me with tablesorter 2.0 I was using it then I needed the filtering but theirs kinda sucked so I found datatables what had such a bigger api and developed more. So I am wondering if there is something like datatables(in terms of development and features) just for notifications instead.

• PHP memcached: getDelayed & getMulti - how to use?

  - by Industrial

  Hi everybody, I have thought a bit recently about how to use getDelayed and getMulti in a PHP application, and their difference. From reading the documentation about getDelayed: "The method does not wait for response and returns right away. When you are ready to collect the items, call either Memcached::fetch or Memcached::fetchAll." So obviously there's a need to call fetchAll before having the keys available, unlike getMulti. But when is the actual memcached call being done? At fetchAll or when getDelayed is run?

• Throwing an AggregateException in my own code

  - by Pat

  How should I go about collecting exceptions and putting them into an AggregateException to re-throw? For my specific code, I have a loop and will have zero or more exceptions thrown from a part of the code. I was hoping to just add the new exceptions to the AggregateException as they arise, but the documentation sort of indicates that it should be constructed with all the Exceptions at once (there is no method to add an Exception to the object). And what about creating a new AE every time and just including the previous AE in the list of exceptions? Seems a hokey way to do it. Any better ideas?

• emacs debugger: how can I step-out, step-over ?

  - by Cheeso

  I don't know why I'm having so much trouble groking the documentation for the elisp debugger. I see it has a commands to "step-into" (d). But for the life of me, I cannot see a step-out or step-over. Can anyone help? If I have this in the Backtrace buffer: Debugger entered--returning value: 5047 line-beginning-position() * c-parse-state() * byte-code("...") * c-guess-basic-syntax() c-show-syntactic-information(nil) call-interactively(c-show-syntactic-information) ...where do I put the cursor, and what key do I type, to step out of the parse-state() fn ? by that I mean, run until that fn returns, and then stop in the debugger again.

• QuickTime movie disappearing from Javascript when scrolled offscreen in Firefox?

  - by c-had

  I have a web page I'm creating that uses Javascript to control an embedded QuickTime player. I add the QuickTime movie to the page using the AC_QuickTime.js file from Apple (as described here - http://developer.apple.com/mac/library/documentation/QuickTime/Conceptual/QTScripting_HTML/QTScripting_HTML_Document/ScriptingHTML.html#//apple_ref/doc/uid/TP40001525-2-SW1 ). Everything seems to be working fine - I can call methods on the QuickTime movie and control its playback (as well as get the current timestamp). The problem is that in Firefox, when I scroll down such that the QuickTime player is no longer visible, I get the following error every time I try to call a method on the QuickTime movie: Error calling method on NPObject! This does not occur in Safari. Why is this happening, and is there any way to work around this?

• Embedded quicktime video pause on click how to prevent?

  - by Marek

  I embedded a quicktime video in firefox. It works, but i would like to prevent the users to stop the video by clicking on it with the left mouse button. Reading the apple documentation i didn't find any answear. I came up with a workaround, i just put an almost invisible div over the whole video. The workaround works in firefox for os X, but oddly does not for the same version of firefox in windows. I would appreciate a way, workaround or not, to achive this at least in the windows/firefox environment. Thanks!

• Is this basically what an IOC like NInject does?

  - by mrblah

  Normally I would do this: public class DBFactory { public UserDAO GetUserDao() { return new UserDao(); } } Where UserDao being the concrete implementation of IUserDao. So now my code will be littered with: DBFactory factory = new DBFactory(); IUserDao userDao = factory.GetUserDao(); User user = userDao.GetById(1); Now if I wanted to swap implementaitons, I would have to go to my DBFactory and change my code to call a different implementation. Now if I used NINject, I would bind the specific implementation on application startup, or via a config file. (or bind based on specific parameters etc. etc.). Is that all there is too it? Or is there more? (reason I am asking if I want to know how it will help me here: http://stackoverflow.com/questions/1930328/help-designing-a-order-manager-class)

• How to test if Scala combinator parser matches a string

  - by W.P. McNeill

  I have a Scala combinator parser that handles comma-delimited lists of decimal numbers. object NumberListParser extends RegexParsers { def number: Parser[Double] = """\d+(\.\d*)?""".r ^^ (_.toDouble) def numbers: Parser[List[Double]] = rep1sep(number, ",") def itMatches(s: String): Boolean = parseAll(numbers, s) match { case _: Success[_] => true case _ => false } } The itMatches function returns true when given a string that matches the pattern. For example: NumberListParser.itMatches("12.4,3.141") // returns true NumberListParser.itMatches("bogus") // returns false Is there a more terse way to do this? I couldn't find one in the documentation, but my function sees a bit verbose, so I wonder if I'm overlooking something.

• How do I package an SDK (static lib + xibs) for the iPhone?

  - by twhipple

  I am creating an SDK for a client that includes predefined view controllers. What is the recommended way to package everything (static lib, .xib(s), and .png(s)) for easy use? SDKs that I've used (e.g. Pinch Media) do a good job of just providing a .h and .a file that expose only user accessible functionality and hiding everything else. As I read Apple's documentation, a framework would be ideal but is not permitted on iPhoneOS. Some key requirements: Don't expose source or object internals. Be easy to use & set up. Work on both the device and simulator. Thanks!

• How can I write fast colored output to Console?

  - by Statement

  Hello world! I want to learn if there is another (faster) way to output text to the console application window using C# .net than with the simple Write, BackgroundColor and ForegroundColor methods and properties? I learned that each cell has a background color and a foreground color, and I would like to cache/buffer/write faster than using the mentioned methods. Maybe there is some help using the Out buffer, but I don't know how to encode the colors into the stream, if that is where the color data resides. This is for a retrostyle textbased game I am wanting to implement where I make use of the standard colors and ascii characters for laying out the game. Please help :)

• Silverlight Spring Effect on TextBlock control

  - by CJCraft.com

  Hi, I'd like to create view that if the user clicks on a control, let's say a TextBlock, that the control would spring back and forth in place from where the user clicked. By spring I mean push back and forth like if there were springs behind the TextBlock in each corner. I've seen demos of this type of effect, and for the life of me, I can't come up with the name of the effect to help with searches, or find an example of this. Maybe instead of a TextBlock it would help to image a picture that could be pressed down on, and as if springs were behind it and then would bounce back into place.
