  • Variable might not have been initialized error

    - by David
    When i try to compile this: public static Rand searchCount (int[] x) { int a ; int b ; ... for (int l= 0; l<x.length; l++) { if (x[l] == 0) a++ ; else if (x[l] == 1) b++ ; } ... } I get these errors: Rand.java:72: variable a might not have been initialized a++ ; ^ Rand.java:74: variable b might not have been initialized b++ ; ^ 2 errors it seems to me that i initialized them at the top of the method. Whats going wrong?

  • How do I deliver mail for wildcard addresses to a particular user/alias/program?

    - by David M
    I need to configure sendmail so that mail delivered for wildcard addresses is accepted for delivery and then delivered to a user, alias, or directly to a script. I can rewrite the envelope/headers any number of ways, but I don't know how to accept the wildcard address when it's provided in RCPT TO: Everything I've tried so far winds up with a 550 user unknown error. So here's a specific example: I want to be able to handle any address that consists of a series of digits followed by a dot followed by a word, then pipe that to a script. If the headers get rewritten, that's OK, but I need the envelope to contain the actual Delivered-To address. Here's the sort of SMTP session I need: 220 blah.foo.com ESMTP server ready; Thu, 22 Apr 2010 20:41:08 -0700 (PDT) HELO blort.foo.com 250 blah.foo.com Hello blort.foo.com [10.1.2.3], pleased to meet you MAIL FROM: <[email protected]> 250 2.1.0 <[email protected]>... Sender ok RCPT TO: <[email protected]> 250 2.1.5 <[email protected]>... Recipient ok I tried some stuff with regex maps, but I never got past 550 user unknown.

  • Resolving Assemblies, the fuzzy way

    - by David Rutten
    Here's the setup: A pure DotNET class library is loaded by an unmanaged desktop application. The Class Library acts as a plugin. This plugin loads little baby plugins of its own (all DotNET Class Libraries), and it does so by reading the dll into memory as a byte-stream, then Assembly asm = Assembly.Load(COFF_Image); The problem arises when those little baby plugins have references to other dlls. Since they are loaded via the memory rather than directly from the disk, the framework often cannot find these referenced assemblies and is thus incapable of loading them. I can add an AssemblyResolver handler to my project and I can see these referenced assemblies drop past. I have a reasonably good idea about where to find these referenced assemblies on the disk, but how can I make sure that the Assmebly I load is the correct one? In short, how do I reliably go from the System.ResolveEventArgs.Name field to a dll file path, presuming I have a list of all the folders where this dll could be hiding)?

  • Helping managers and customers understand SOA

    - by David
    I frequently hear Service-Oriented Architecture (SOA) being tossed around as a buzzword among non-technical customers or program managers with little concern or understanding for what it actually entails (example: "Can I buy a SOA?"). There's also a lot of misinformation about SOA (example: "Only web apps can use SOA") and a general lack of understanding for its capabilities (example: "SOA can make your make all of your data work together"). What are some key facts that you, as someone who understand the technical side of SOA, use to educate program managers on the appropriate use and understanding of SOA? What's the best way to set the record straight with non-technical folks?

  • GetAcceptExSockaddrs returns garbage! Does anyone know why?

    - by David
    Hello, I'm trying to write a quick/dirty echoserver in Delphi, but I notice that GetAcceptExSockaddrs seems to be writing to only the first 4 bytes of the structure I pass it. USES SysUtils; TYPE BOOL = LongBool; DWORD = Cardinal; LPDWORD = ^DWORD; short = SmallInt; ushort = Word; uint16 = Word; uint = Cardinal; ulong = Cardinal; SOCKET = uint; PVOID = Pointer; _HANDLE = DWORD; _in_addr = packed record s_addr : ulong; end; _sockaddr_in = packed record sin_family : short; sin_port : uint16; sin_addr : _in_addr; sin_zero : array[0..7] of Char; end; P_sockaddr_in = ^_sockaddr_in; _Overlapped = packed record Internal : Int64; Offset : Int64; hEvent : _HANDLE; end; LP_Overlapped = ^_Overlapped; IMPORTS function _AcceptEx (sListenSocket, sAcceptSocket : SOCKET; lpOutputBuffer : PVOID; dwReceiveDataLength, dwLocalAddressLength, dwRemoteAddressLength : DWORD; lpdwBytesReceived : LPDWORD; lpOverlapped : LP_OVERLAPPED) : BOOL; stdcall; external MSWinsock name 'AcceptEx'; procedure _GetAcceptExSockaddrs (lpOutputBuffer : PVOID; dwReceiveDataLength, dwLocalAddressLength, dwRemoteAddressLength : DWORD; LocalSockaddr : P_Sockaddr_in; LocalSockaddrLength : LPINT; RemoteSockaddr : P_Sockaddr_in; RemoteSockaddrLength : LPINT); stdcall; external MSWinsock name 'GetAcceptExSockaddrs'; CONST BufDataSize = 8192; BufAddrSize = SizeOf (_sockaddr_in) + 16; VAR ListenSock, AcceptSock : SOCKET; Addr, LocalAddr, RemoteAddr : _sockaddr_in; LocalAddrSize, RemoteAddrSize : INT; Buf : array[1..BufDataSize + BufAddrSize * 2] of Byte; BytesReceived : DWORD; Ov : _Overlapped; BEGIN //WSAStartup, create listen socket, bind to port 1066 on any interface, listen //Create event for overlapped (autoreset, initally not signalled) //Create accept socket if _AcceptEx (ListenSock, AcceptSock, @Buf, BufDataSize, BufAddrSize, BufAddrSize, @BytesReceived, @Ov) then WinCheck ('SetEvent', _SetEvent (Ov.hEvent)) else if GetLastError <> ERROR_IO_PENDING then WinCheck ('AcceptEx', GetLastError); {do WaitForMultipleObjects} _GetAcceptExSockaddrs (@Buf, BufDataSize, BufAddrSize, BufAddrSize, @LocalAddr, @LocalAddrSize, @RemoteAddr, @RemoteAddrSize); So if I run this, connect to it with Telnet (on same computer, connecting to localhost) and then type a key, WaitForMultipleObjects will unblock and GetAcceptExSockaddrs will run. But the result is garbage! RemoteAddr.sin_family = -13894 RemoteAddr.sin_port = 64 and the rest is zeroes. What gives? Thanks in advance!

  • Luntbuild + svn - set tagging directory using variables

    - by David Belanger
    Hi, I'm using Luntbuild with Subversion and would like to have our svn tagging environment specific (dev, testing, etc.) and I'm wondering if there's a way to use a variable in the VCS Adapters section. I'm looking for something like this: Directory for tags: tags/Builds/${env}/Service Where ${env} is a variable I can set in the Luntbuild builders section or elsewhere. Does anyone know if what I'm wanting is possible? Thanks.

  • How do I make an iframe 100% height of a containing div in Firefox?

    - by David
    I'm having some trouble figuring out how to extend an iframe to 100% of it's container element in Firefox and IE (it works fine in Chrome). From searching around, it makes sense that there has to be a width specified on the containing div (and possibly body and html as well). However, I have done that, and the iframe is still not extending. Do all of the parent divs have to have a specified width and position for this to work, or just the containing parent? Any fix for this would be greatly appreciated! Here's what I have: <!DOCTYPE html> <html> <head> <style> html, body {margin:0; padding:0; height:100%} #container {width: 1000px; min-height: 550px; position: relative} #smallContainer {position:relative} /*no width specified*/ #iframeContainer {height: 100%; position: relative} #iframe {height: 100%; width: 100%; display: block} </style> </head> <body> <div id="container"> <div id="smallContainer"> <div id="iframeContainer"> <iframe id="iframe" src="foo.com"></iframe> </div> </div> </div> </body> </html>

  • iPhone Application: force landscape mode, strange behaviour...?

    - by David Lawson
    This is a method I use to switch display views, based on a string passed (for example you could pass MainMenuViewController to switch views to a new instance of that class): - (void)displayView:(NSString *)newView { NSLog(@"%@", newView); [[currentView view] removeFromSuperview]; [currentView release]; UIViewController *newView = [[NSClassFromString(newView) alloc] init]; [[newView view] setFrame:CGRectMake(0, 0, 320, 460)]; [self setCurrentView:newView]; [[self view] addSubview:[currentView view]]; } I have my application forced into landscape view (.plist and -shouldRotate), but if you look in the code: [[newView view] setFrame:CGRectMake(0, 0, 320, 460)]; I have to set the frame of the newView to a portrait frame for the view to be displayed correctly - otherwise, for example, a button on the new view can only be pressed in certain parts of the screen (rectangle up the top), unresponsive anywhere else. Even though in all my NIB files they are set to landscape.

  • How do I secure a .NET Web Service for use by an iPhone application?

    - by David A Gibson
    Hello, The title says it all, I have a Web Service written in .NET that provides data for an iPhone application. It will also allow the application make a "reservation." Currently it's all internal to the corporate network but obviously when the iPhone application is published I will need ensure the Web Service is available externally. How would I go about securing the Web Service? There are two aspects I'm looking into: Authentication for accessing the web service Protection for the data being transferred I'm no so bothered about the data being passed back and forth as it will be viewable in the application anyway (which will be free). The key issue for me is preventing users from accessing the Web Service and making reservations themselves. At the moment I am considering encrypting any strings in the XML data passed back and forth so only the client can effectively use the web service sidestepping the need for authentication and providing protection for the data. This is the only model I have seen but I think the overheads on the iPhone and even for the web service make for a poor user experience. Any solutions at all would be most welcome? Thanks

  • How did this get 8?

    - by David
    Here's the code: class qual { public static int fibonacci(int n) { if (n == 0 || n == 1) { return 1; } else { return fibonacci(n-1) + fibonacci(n-2); } } public static void main(String[] arg) { System.out.println(fibonacci(5)); } } The output was 8. The output should be 8 but when I look at this I think it should be 7 ((5-1) +(5-2)). Why was the output 8? I think the reasoning behind getting 8 will make recursion maybe stop being confusing for me.

  • Xcode: view references for a variable?

    - by David.Chu.ca
    I am new to Xcode. I am not sure if there is a way to view a variable's references just like "Find all references" in Visual Studio by right click on a var? For example, in my .h file, I would like to know or view all the references for property isSet: @interface MyInterface { ... BOOL isSet; // view all references to this var? ... }

  • Getting true video Height/Width from ASF videos

    - by David
    I am trying to convert an ASF video with FFMPEG using an interface called mediahandler. The issue is, the metadata on the ASF video appears to be corrupt. It states that the video is 640x240, and 4:3 aspect ratio. The aspect ratio is correct, but obviously the resolution is not. This causes the converter to incorrectly scale the video, because it uses the resolution to determine the original aspect ratio. I am able to get the aspect ratio metadata, but I'm not sure this solves the issue, because I would think that if the resolution could be incorrect, then so could the aspect ratio metadata. So, is there any way to get the actual height/width? It appears that players like VLC have no issue with this. How do I do such a thing w/ FFMPEG?

  • Android: Defined array resource not found ?!

    - by David
    Hi, i have a strange (?) error in my android application. I have defined some arrays in values/arrays.xml the following way: <?xml version="1.0" encoding="utf-8"?> <resources> <array name="perimeter"> <item>10 miles</item> <item>20 miles</item> <item>30 miles</item> </array> <array name="regvalues"> <item>1</item> <item>2</item> <item>3</item> </array> </resources> Now I want to use them in a ListPreference for a PreferenceActivity (defined by an xml file). So i set android:entries="@array/perimeter" android:entryValues="@array/regvalues" for this ListPreference. When I try to use this on my device the app crashes. (NullPointer in Dialog.close()) If I try to use the regvalues-items as Entries for the ListPreference i get a NullPointer in ArrayAdapter.createViewFromResource(int, View, ViewGroup, int) line: 355 So there seems to be sth wrong with the regvalues array. But what ?!? Eclipse shows me no errors at compile time. So everything in the xml-file and java-code is written correctly and there are no typos. Where is the problem?!?

  • PHP / javascript live chat using too much bandwidth

    - by David
    So I am learning about javascript, so I am making a live chat system with PHP and javascript. I have it so the javascript refreshes the log (each message gets logged in a file on the server), and it refreshes every second. Im using firebug to monitor the resource usage, and I see under the net tab each times its updated, and the bytes add up really fast. I know I can change it to update less, but is there a way that when a user on the other end I'm talking to, when the send a message, it gets sent to the server, then an alert gets sent to me saying that the chatlog needs to update somehow. That way it only updates when the log is updated. let me know, thanks

  • Android: Learning the platform, have any app suggestions?

    - by David
    I'm beginning to learn mobile programming on the Android platform. I'm up for working with any particular base SDK. I just want to hear some suggestions from the community about what types of applications I should start with to help learn more advanced interactions with the platform. There are of course the Standard Hello World, calculator, etc. But by now I am bored with all of those. What do you all make when learning a new language?

  • Efficient way to maintain a sorted list of access counts in Python

    - by David
    Let's say I have a list of objects. (All together now: "I have a list of objects.") In the web application I'm writing, each time a request comes in, I pick out up to one of these objects according to unspecified criteria and use it to handle the request. Basically like this: def handle_request(req): for h in handlers: if h.handles(req): return h return None Assuming the order of the objects in the list is unimportant, I can cut down on unnecessary iterations by keeping the list sorted such that the most frequently used (or perhaps most recently used) objects are at the front. I know this isn't something to be concerned about - it'll make only a miniscule, undetectable difference in the app's execution time - but debugging the rest of the code is driving me crazy and I need a distraction :) so I'm asking out of curiosity: what is the most efficient way to maintain the list in sorted order, descending, by the number of times each handler is chosen? The obvious solution is to make handlers a list of (count, handler) pairs, and each time a handler is chosen, increment the count and resort the list. def handle_request(req): for h in handlers[:]: if h[1].handles(req): h[0] += 1 handlers.sort(reverse=True) return h[1] return None But since there's only ever going to be at most one element out of order, and I know which one it is, it seems like some sort of optimization should be possible. Is there something in the standard library, perhaps, that is especially well-suited to this task? Or some other data structure? (Even if it's not implemented in Python) Or should/could I be doing something completely different?

  • Convert codes to HTML with CSS style

    - by David.Chu.ca
    I normally use VIM to edit my codes and convert them to HTML by using TOhtml command. The only thing I don't like is that the converted HTML does not have css class style definitions. I am not sure if there is tool to convert codes to HTML with css, or I can use additional tool or command to convert HTML HTML with css?

  • How can I determine when an InnoDB table was last changed?

    - by David M
    I've had success in the past storing the (heavily) processed results of a database query in memcached, using the last update time of the underlying tables(s) as part of the cache key. For MyISAM tables, that last changed time is available in SHOW TABLE STATUS. Unfortunately, that's usually NULL for InnoDB tables. In MySQL 4.1, the ctime for an InnoDB in its SHOW TABLE STATUS line was usually its actual last update time, but that doesn't seem to be true for MySQL 5.1. There is a DATETIME field in the table, but it only shows when a row has been modified - it cannot show the deletion time of a row that's not there anymore! So, I really cannot use MAX(update_time). Here's the really tricky part. I have a number of replicas that I do reads from. Can I figure out the state of the table that doesn't rely on when the changes have actually been applied? My conclusion after working on this for a while is that it's not going to be possible to get this information as cheaply as I'd like. I'm probably going to cache data until the time that I expect the table to change (it's updated once a day), and let the query cache help out where it can.

  • Actionscript Enterframe Movement

    - by David
    I am trying to make accelerated movement, but I am running into a problem that, for the life of me, I cannot understand. My class definition: public class Player extends MovieClip { private var stageRef:Stage; private var key:KeyObject; private var acceleration:int = .5; private var curSpeed:int = 0; public function Player(stageRef:Stage) { this.stageRef = stageRef; addEventListener(Event.ENTER_FRAME, enterFrame); key = new KeyObject(stageRef); } public function enterFrame(e:Event) : void { if(key.isDown(key.RIGHT)) { x += 5; } } } This works to move my position in the x direction at a constant rate. However, if I change enterFrame to public function enterFrame(e:Event) : void { if(key.isDown(key.RIGHT)) { x += acceleration; } } No movement occurs. Is there something going on in the event I do not understand? Why is it that I can have x increased by a constant value but not a constant value as defined in a variable in the class? Is it a scope issue?

  • How to set a filter for an estimated maximum price

    - by David
    I cannot figure out how to set an estimated maximum price for a collection of records. What I want to avoid is to simply use SQL MAX, because maybe there are records with exorbitant prices. For example, in the "computers-hardware" category of OLX (http://www.olx.com/computers-hardware-cat-240) the filter for maximum price is estimately set to $1400, but sorting by price, the first items are above $10000 Maybe they calculated the average and then estimated some maximum price... what do you think? And what about the stepping? How would you calculate it?

  • Installed Android on Mac, cannot find SDK

    - by David Matuszek
    Using Mac OS X 10.6.2, Eclipse SDK 3.5.2. I installed the Android plugin, following the instructions at: http://developer.android.com/sdk/eclipse-adt.html In the next section (step #3) it says: For the SDK Location in the main panel, click Browse... and locate your downloaded SDK directory. I cannot find such a directory. When I try some other directory, it says the directory has no 'tools' folder, so I've searched for a 'tools' folder, but none of those found (of 15 or 20) appear to be Android. Where is this directory??? --Dave [email protected]
